ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced EBC system.
This system includes the Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Stability Control (ESC),
Electronic Roll Mitigation (ERM), Hill Start Assist (HSA),
Intersection Collision Assist (ICA), and Traction Control
System (TCS). These systems work together to enhance
both vehicle stability and control in various driving
conditions.
Your vehicle may also be equipped with Dynamic Steering
Torque (DST), Rain Brake Support (RBS), Ready Alert
Braking (RAB), and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking torque
between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent
overslip of the rear wheels to avoid vehicle instability, and
to prevent the rear axle from entering ABS before the
front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
NOTE:
ERM is disabled any time the ESC is in “Full Off” mode (if
equipped). See
Úpage 242 for a complete explanation of
the available ESC modes.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The
capabilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user's safety or the safety of
others.
WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user's safety or the safety of
others.

242SAFETY
Electronic Stability Control (ESC)
ESC enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying
the brake of the appropriate wheel(s) to assist in
counteracting these conditions. Engine power may also be
reduced to help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
 Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the oversteer
or understeer condition.
The ESC Activation/Malfunction Indicator Light located in
the instrument cluster will start to flash as soon as the ESC
system becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when the Traction Control
System (TCS) is active. If the ESC Activation/Malfunction
Indicator Light begins to flash during acceleration, ease up
on the accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the prevailing
road conditions.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
To enter the “Partial Off” mode, momentarily push the ESC
OFF button and the ESC OFF Indicator Light will illuminate.
To turn the ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.
NOTE:For vehicles with multiple partial ESC modes, the push and
release of the button will toggle the ESC modes. Multiple
attempts may be required to return to "ESC On" mode.
WARNING!
 Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capabil -
ities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

SAFETY243
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator Light
in the instrument cluster will come on when the
ignition is placed in the ON/RUN mode. It
should go out with the engine running. If the
ESC Activation/Malfunction Indicator Light comes on
continuously with the engine running, a malfunction has
been detected in the ESC system. If this light remains on
after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as soon as possible to have the problem diagnosed and corrected. The ESC Activation/Malfunction Indicator Light starts to
flash as soon as the tires lose traction and the ESC system
becomes active. The ESC Activation/Malfunction Indicator
Light also flashes when TCS is active. If the ESC
Activation/Malfunction Indicator Light begins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
The ESC OFF Indicator Light indicates the
customer has elected to have the Electronic
Stability Control (ESC) in a reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light and the
ESC OFF Indicator Light come on momentarily each
time the ignition is placed in the ON/RUN mode.
 Each time the ignition is placed in the ON/RUN mode,
the ESC system will be on even if it was turned off previ -
ously.
 The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off-road driving
while in 4WD Low. HDC maintains vehicle
speed while descending hills during various
driving situations. HDC controls vehicle speed
by actively controlling the brakes. HDC Has Three States:

1. Off (feature is not enabled and will not activate).

2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable HDC:
 The driveline is in 4WD Low.
 The vehicle speed is below 5 mph (8 km/h).
 The parking brake is released.
 The driver door is closed.
Activating HDC
Once HDC is enabled it will activate automatically if driven
down a grade of sufficient magnitude. The set speed for
HDC is selectable by the driver, and can be adjusted by
using the gear shift +/-. The following summarizes the
HDC set speeds:
WARNING!
 When in “Partial Off” mode, the TCS functionality of
ESC, except for the limited slip feature described in
the TCS section, has been disabled and the ESC OFF
Indicator Light will be illuminated. When in “Partial
Off” mode, the engine power reduction feature of
TCS is disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
 Trailer Sway Control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.

23_WS_OM_EN_USC_t.book Page 243

246SAFETY
The set speed for SSC is selectable by the driver, and can
be adjusted by using the gear shift +/-. Additionally, the
SSC set speed may be reduced when climbing a grade and
the level of set speed reduction depends on the
magnitude of grade. The following summarizes the SSC
set speeds:
SSC Target Set Speeds
1st = .6 mph (1 km/h)
 2nd = 1.2 mph (2 km/h)
 3rd = 1.8 mph (3 km/h)
 4th = 2.5 mph (4 km/h)
 5th = 3.1 mph (5 km/h)
 6th = 3.7 mph (6 km/h)
 7th = 4.3 mph (7 km/h)
 8th = 5 mph (8 km/h)
 9th = 5.6 mph (9 km/h) – If Equipped
 REVERSE = .6 mph (1 km/h)
 NEUTRAL = 1.2 mph (2 km/h)
 PARK = SSC remains enabled but not active
NOTE:
During SSC the +/- shifter input is used for SSC target
speed selection but will not affect the gear chosen by
the transmission. While actively controlling SSC the
transmission will shift appropriately for the
driver-selected set speed and corresponding driving
conditions.
 SSC performance is influenced by the Select-Terrain
mode. This difference may be notable to the driver and
may be perceived as a varying level of aggressiveness. Driver Override:
The driver may override SSC activation with throttle or
brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:

Driver overrides SSC set speed with throttle or brake
application
 Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h)
 Vehicle is shifted to PARK
Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
 The driver pushes the SSC switch.
 The driveline is shifted out of 4WD Low.
 The parking brake is applied.
 The driver door opens.
 The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
 The vehicle is driven greater than 40 mph (64 km/h)
(SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and the SSC
switch has an LED which offers feedback to the driver
about the state SSC is in.
 The cluster icon and switch light will illuminate and
remain on solid when SSC is enabled or activated. This
is the normal operating condition for SSC. 
The cluster icon and switch light will flash for several
seconds then extinguish when the driver pushes the
SSC switch but enable conditions are not met.
 The cluster icon and switch light will flash for several
seconds then extinguish when SSC disables due to
excess speed.
 The cluster icon and switch light will flash then extin -
guish when SSC deactivates due to overheated brakes.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more engine power to be applied to the wheel that is
not spinning. BLD may remain enabled even if the TCS and
Electronic Stability Control (ESC) are in reduced modes.
WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off-road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.

23_WS_OM_EN_USC_t.book Page 246

SAFETY247
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the appropriate
actions to attempt to stop the sway. TSC will become
active automatically once an excessively swaying trailer is
recognized.
NOTE:TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations
Úpage 178.
When TSC is functioning, the ESC Activation/Malfunction
Indicator Light will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” mode.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM)
BSM system uses two radar sensors, located inside the
rear fascia/bumper, to detect highway licensable vehicles
(automobiles, trucks, motorcycles, etc.) that enter the
blind spot zones from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear.
The BSM detection zone covers approximately one lane in
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the side of the vehicle, near the B-pillar,
and extends approximately 10 ft (3 m) beyond the rear
fascia/bumper of the vehicle. The BSM system monitors
the detection zones on both sides of the vehicle when the
vehicle speed is 7 mph (11 km/h) or higher and will alert
the driver of vehicles in these areas. BSM will alert earlier
on faster-approaching vehicles – up to 33 mph (54 km/h)
difference.
NOTE:The BSM system detection zone DOES NOT change if your
vehicle is towing a trailer. Therefore, visually verify the
adjacent lane is clear for both your vehicle and trailer
before making a lane change. If the trailer or other object
(i.e., bicycle, sports equipment) extends beyond the side of your vehicle, this may result in random false detections
on the trailer, and false chimes when the turn signal is
used
Úpage 197.
The BSM system can become blocked if snow, ice, mud, or
other road contaminations accumulate on the rear fascia/
bumper where the radar sensors are located. The system
may also detect blockage if the vehicle is operated in
areas with extremely low radar returns such as a desert or
parallel to a large elevation drop. If blockage is detected,
a “Blind Spot Temporarily Unavailable, Sensor Blocked”
message will display in the cluster, both mirror lights will
illuminate, and BSM and RCP alerts will not occur. This is
normal operation. The system will automatically recover
and resume function when the condition clears or when
an ignition cycle occurs. To minimize system blockage, do
not block the area of the rear fascia/ bumper where the
radar sensors are located with foreign objects (bumper
stickers, bicycle racks, etc.) and keep it clear of road
contaminations.

Sensor Location (Left Side Shown)

WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

250SAFETY
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime mode,
the BSM system will provide a visual alert in the
appropriate side view mirror based on a detected object.
If the turn signal is then activated, and it corresponds to
an alert present on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn signal and
detected object are present on the same side at the same
time, both the visual and audible alerts will be issued. In
addition to the audible alert the radio (if on) will also be
muted.
NOTE:Whenever an audible alert is requested by the BSM
system, the radio is also muted.
When the system is in RCP, the system shall respond with
both visual and audible alerts when a detected object is
present. Whenever an audible alert is requested, the radio
is also muted. Turn/hazard signal status is ignored; the
RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off, there will be no visual
or audible alerts from either the BSM or RCP systems.
NOTE:The BSM system will store the current operating mode
when the vehicle is shut off. Each time the vehicle is
started, the previously stored mode will be recalled and
used.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION
FCW with Mitigation system provides the driver with
audible warnings, visual warnings (within the instrument
cluster display), and may apply a brake jerk to warn the
driver when it detects a potential frontal collision. The
warnings and limited braking are intended to provide the
driver with enough time to react, avoid or mitigate the
potential collision.
NOTE:FCW monitors the information from the forward looking
sensors as well as the Electronic Brake Controller (EBC), to
calculate the probability of a forward collision. When the
system determines that a forward collision is probable, the
driver will be provided with audible and visual warnings
and may provide a brake jerk warning. If the driver does
not take action based upon these progressive warnings,
then the system will provide a limited level of active
braking to help slow the vehicle and mitigate the potential
forward collision. If the driver reacts to the warnings by
braking and the system determines that the driver intends
to avoid the collision by braking but has not applied suffi -
cient brake force, the system will compensate and provide
additional brake force as required.
If a Forward Collision Warning with Mitigation event begins
at a speed below 39 mph (62 km/h), the system may provide the maximum or partial braking to mitigate the
potential forward collision. If the Forward Collision
Warning with Mitigation event stops the vehicle
completely, the system will hold the vehicle at a standstill
for two seconds and then release the brakes.
FCW Message

When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
will be deactivated.
NOTE:
 The minimum speed for FCW activation is 3 mph
(5 km/h).
 The FCW alerts may be triggered on objects other than
vehicles, such as guardrails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality.
 It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within an ignition cycle, the Active Braking portion of
FCW will be deactivated until the next ignition cycle.
 The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low, the FCW
system will be automatically deactivated.

SAFETY255
Lots of snow or ice around the wheels or wheel
housings.
 Using tire chains on the vehicle.
 Using wheels/tires not equipped with TPMS sensors.
NOTE:There is no Tire Pressure Monitoring System sensor in the
spare tire. The TPMS will not be able to monitor the tire
pressure. If you install the spare tire in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the Tire Pressure Moni -
toring System Warning Light will remain on, a chime will
sound, and the instrument cluster display will still display
a pressure value in the different color graphic display and
an “Inflate to XX” message will be displayed. After driving
the vehicle for up to 20 minutes above 15 mph (24 km/h),
the Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain on solid.
In addition, the instrument cluster display will display a
“SERVICE TPM SYSTEM" message for five seconds and
then display dashes (--) in place of the pressure value. For
each subsequent ignition switch cycle, a chime will sound,
the Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain on solid,
and the instrument cluster display will display a "SERVICE
TPM SYSTEM" message for five seconds and then display
dashes (--) in place of the pressure value. Once you repair
or replace the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS will update
automatically.
In addition, the Tire Pressure Monitoring System Warning
Light will turn off and the graphic in the instrument cluster
display will display a new pressure value instead of
dashes (--), as long as no tire pressure is below the low-pressure warning limit in any of the four active road
tires. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can be
deactivated if replacing all four wheel and tire assemblies
(road tires) with wheel and tire assemblies that do not
have TPMS sensors, such as when installing winter wheel
and tire assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring System sensors. Then, drive the
vehicle for 20 minutes above 15 mph (24 km/h). The TPMS will chime, the TPMS Warning Light will flash on and
off for 75 seconds and then remain on. The instrument
cluster will display the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the pressure
values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPMS
sensors. Then, drive the vehicle for up to 20 minutes
above 15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes. On the next ignition cycle the
"SERVICE TPM SYSTEM" message will no longer be
displayed as long as no system fault exists.
Tire Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill
Alert feature in the apps menu of the Uconnect system.
NOTE:
 The Tire Fill Alert system will only support inflating or
deflating one tire at a time. The user is required to wait
until the hazard lights STOP flashing or 26-30 seconds
after the desired pressure is achieved in one wheel
before switching to another.
 The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the system is
in deactivation mode (if equipped).
The system will be activated when the system detects an
increase in tire pressure while filling the tire. The ignition
must be in the ON/RUN mode with the transmission in
PARK.
NOTE:It is not required to have the engine running to enter Tire
Fill Alert mode.
The hazard lights will come on to confirm the vehicle is in
Tire Fill Alert mode. If the hazard lights do not come on
while inflating the tire, the Tire Pressure Monitoring
System sensor may be in an inoperative position,
preventing the TPMS sensor signal from being received. In
this case, the vehicle may need to be moved slightly
forward or backward.

256SAFETY
When Tire Fill Alert mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:
The horn will chirp once to let the user know when to
stop filling the tire, when it reaches recommended
pressure.
 The horn will chirp three times if the tire is overfilled
and will continue to chirp every five seconds if the user
continues to inflate the tire.
 The horn will chirp once again when enough air is let
out to reach proper inflation level.
 The horn will also chirp three times if the tire is then
underinflated and will continue to chirp every five
seconds if the user continues to deflate the tire.
Selectable Tire Fill Alert (STFA) —
If Equipped
The Selectable Tire Fill Alert (STFA) system is an optional
feature that is included as part of the normal Tire Fill Alert
system. The system is designed to allow you to select a
pressure to inflate or deflate the vehicle's front and rear
axle tires to, and to provide feedback while inflating or
deflating the vehicle's tires.
In the Selectable Tire Fill Alert application, which is located
in the apps menu of the Uconnect system, you will be able
to select a pressure setting for both the front and rear axle
tire pressures by scrolling through a pressure range from
greater than or equal to 15 psi to XX psi in 1 psi
increments for each axle setting.
XX = the vehicle's cold placard pressure values for the
front and rear axles as shown on the vehicle placard
pressure label. You may also store pressure values chosen for each axle
in the Uconnect system application as preset pressure
values. Up to two sets of preset pressure values can be
stored in the Uconnect system for the front and rear axle.
Once you select the tire pressures for the front and rear
axles that you want to inflate or deflate to, you can begin
inflating or deflating one tire at a time.
NOTE:The STFA system will only support inflating or deflating one
tire at a time. The user is required to wait until the hazard
lights STOP flashing or 26-30 seconds after the desired
pressure is achieved in one wheel, before switching to
another.
The system will be activated when the TPMS receiver
module detects a change in tire pressure. The ignition
must be in the ON/RUN mode, with the transmission in
PARK. The hazard lights will come on to confirm the
vehicle is in Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire pressure
screen will be displayed in the instrument cluster. If the
hazard lights do not come on while inflating or deflating
the tire, the Tire Pressure Monitoring System sensor may
be in an inoperative position, preventing the TPMS sensor
signal from being received. In this case, the vehicle may
need to be moved slightly forward or backward.
Horn chirps will indicate STFA status as tires are inflated/
deflated. The horn will chirp under the following STFA
states:

1. The horn will chirp once when the selected pressure
is reached to let you know when to stop inflating or
deflating the tire.

2. The horn will chirp three times if the tire is overin -
flated or over-deflated.
3. The horn will chirp once again when enough air is added or removed to reach proper selected pressure
level.

284SAFETY
The seat belts in the passenger seating positions are
equipped with a Switchable Automatic Locking Retractor
(ALR) that is designed to keep the lap portion of the seat
belt tight around the child restraint so that it is not
necessary to use a locking clip. The ALR retractor can be
“switched” into a locked mode by pulling all of the webbing
out of the retractor and then letting the webbing retract
back into the retractor. If it is locked, the ALR will make a
clicking noise while the webbing is pulled back into the
retractor
