(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” (located in the instrument cluster)
starts to flash as soon as the tires lose trac-
tion 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 con-
ditions.
NOTE:
• The “ESC Activation/Malfunction Indicator
Light” and the “ESC OFF Indicator Light”
come on momentarily each time the igni-
tion is turned ON.
• Each time the ignition is turned ON, the
ESC system will be on even if it was turned
off previously.• The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive following the maneuver that
caused the ESC activation.
The “ESC OFF Indicator Light” indi-
cates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
Electronic Roll Mitigation (ERM)
This system 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 vehi-
cle’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 anytime the ESC is in “Full
Off” mode (if equipped). Refer to “Electronic
Stability Control (ESC)” in this section for a
complete explanation of the available ESC
modes.
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 roll overs, 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.

Feedback To The Driver
The instrument cluster has an HDC icon and
the HDC switch has an indicator light, which
offers feedback to the driver about the state
HDC is in.
• The cluster icon and switch indicator light
will illuminate and remain on solid when
HDC is enabled or activated. This is the
normal operating condition for HDC.
• The cluster icon and switch indicator light
will flash for several seconds then extin-
guish when the driver pushes the HDC
switch but enable conditions are not met.
• The cluster icon and switch indicator light
will flash for several seconds then extin-
guish when HDC disables due to excess
speed.
• The cluster icon and switch indicator light
will flash when HDC deactivates due to
overheated brakes. The flashing will stop
and HDC will activate again once the brakes
have cooled sufficiently.WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descend-
ing hills. The driver must remain attentive
to the driving conditions and is responsible
for maintaining a safe vehicle speed.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) — If
Equipped
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the taillights, to detect highway licensable
vehicles (automobiles, trucks, motorcycles,
etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.When the vehicle is started, the BSM warning
light will momentarily illuminate in both out-
side rear view mirrors to let the driver know
that the system is operational. The BSM
system sensors operate when the vehicle is in
any forward gear or REVERSE and enters
stand-by mode when the vehicle is in PARK.
The BSM detection zone covers approxi-
mately one lane width on both sides of the
vehicle 12 ft (3.8 m). The zone length starts
at the outside rear view mirror and extends
approximately 10 ft (3 m) beyond the rear
bumper of the vehicle. The BSM system
monitors the detection zones on both sides of
Rear Detection Zones

using an accurate tire pressure gauge, even
if underinflation has not reached the level
to trigger illumination of the TPMS Warning
Light.
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
System Operation
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the receiver module.
NOTE:
It is particularly important for you to check
the tire pressure in all of the tires on your
vehicle monthly and to maintain the proper
pressure.The TPMS consists of the following compo-
nents:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system
messages, which display in the instrument
cluster
• Tire pressure monitoring telltale light
Tire Pressure Monitoring Low Pressure Warn-
ings
The TPMS Warning Light will illumi-
nate in the instrument cluster and a
chime will sound when tire pressure
is low in one or more of the four active road
tires. In addition, the instrument cluster will
display a "Tire Low" message for a minimum
of five seconds and a graphic showing the
pressure values of each tire with the low tire
pressure values in a different color.
Tire Pressure Monitoring Display
SAFETY
96

Should this occur, you should stop as soon as
possible and inflate the tires with low pres-
sure (those in a different color in the instru-
ment cluster graphic) to the vehicle’s recom-
mended cold placard pressure value. Once
the system receives the updated tire pres-
sures, the system will automatically update,
the pressure values in the graphic display in
the instrument cluster will return to their
original color, and the TPMS Warning Light
will turn off.NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold plac-
ard pressure in order to turn the TPMS Warn-
ing Light off. The vehicle may need to be
driven for up to 10 minutes above 15 mph
(24 km/h) in order for the TPMS to receive
this information.
Service TPMS Warning
When a system fault is detected, the TPMS
Warning Light will flash on and off for 75 sec-
onds and then remain on solid. The system
fault will also sound a chime. In addition, the
instrument cluster will display a "SERVICE
TIRE PRESSURE SYSTEM" message for a
minimum of five seconds and then display
dashes (- -) in place of the pressure value to
indicate which sensor is not being received.
If the ignition is cycled, this sequence will
repeat, providing the system fault still exists.
If the system fault no longer exists, the TPMS
Warning Light will no longer flash, and the
“SERVICE TIRE PRESSURE SYSTEM” mes-sage will no longer display, and a pressure
value will display in place of the dashes. A
system fault can occur due to any of the
following:
• Jamming due to electronic devices or driv-
ing next to facilities emitting the same
radio frequencies as the TPMS sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.
• 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.
Vehicles With Compact Spare or Non-Matching
Full Size Spare
1. The compact spare tire or non-matching
full size does not have a tire pressure
monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the com-
pact spare tire.
2. If you install the compact or non-
matching full size spare tire in place of a
road tire that has a pressure below the
low-pressure warning limit, upon the next
Tire Pressure Monitoring Low Pressure
Warning
97

ignition cycle, the TPMS Warning Light
will remain on and a chime will sound. In
addition, the graphic in the instrument
cluster will still display a different color
pressure value.
3. After driving the vehicle for up to 10 min-
utes above 15 mph (24 km/h), the TPMS
Warning Light will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will dis-
play a “Service Tire Pressure System”
message for five seconds and then display
dashes (- -) in place of the pressure value.
4. For each subsequent ignition cycle, a
chime will sound, the TPMS Warning
Light will flash on and off for 75 seconds
and then remain on solid, and the instru-
ment cluster will display a “SERVICE
TIRE PRESSURE SYSTEM” message for
five seconds and then display dashes (- -)
in place of the pressure value.
5. Once you repair or replace the original
road tire and reinstall it on the vehicle in
place of the compact spare or non-
matching full size, the TPMS will update
automatically. In addition, the TPMSWarning Light will turn off and the graphic
in the instrument cluster 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 10 minutes
above 15 mph (24 km/h) in order for the
TPMS to receive this information.
Vehicles With a Full Size Matching Spare
1. If your vehicle is equipped with a match-
ing full-size spare wheel and tire assem-
bly, it has a tire pressure monitoring sen-
sor, and can be monitored by the Tire
Pressure Monitoring System (TPMS)
when swapped with a low pressure road
tire.
2. In the event that the matching full-size
spare tire is swapped with a low pressure
road tire, the next ignition switch cycle
will still show the TPMS Warning Light to
be on, a chime to sound, and the graphic
display will still show the low tire pressure
value in a different color.3. Driving the vehicle for up to 10 minutes
above 15 mph (24 km/h) will turn off the
TPMS Warning Light as long as none of
road tires are below the low pressure
warning threshold.
TPMS Deactivation — If Equipped
The 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 Moni-
toring (TPM) Sensors. Then, drive the vehicle
for 10 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 dis-
play the “SERVICE TIRE PRESSURE SYS-
TEM” message and then display dashes (--)
in place of the pressure values.
SAFETY
98

Beginning with the next ignition cycle, the
TPMS will no longer chime or display the
“SERVICE TIRE PRESSURE SYSTEM” mes-
sage 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 10 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 TIRE
PRESSURE SYSTEM” message and then dis-
play pressure values in place of the dashes.
On the next ignition cycle the "SERVICE TIRE
PRESSURE SYSTEM" message will no longer
be displayed as long as no system fault exists.
OCCUPANT RESTRAINT
SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
Occupant Restraint Systems Features
• Seat Belt Systems
• Supplemental Restraint Systems (SRS) Air
Bags
• Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
Important Safety Precautions
Please pay close attention to the information
in this section. It tells you how to use your
restraint system properly, to keep you and
your passengers as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying
air bag:
1. Children 12 years old and under should
always ride buckled up in the rear seat of
a vehicle with a rear seat.2. A child who is not big enough to wear the
vehicle seat belt properly (Refer to “Child
Restraints” in this section for further in-
formation) must be secured in the appro-
priate child restraint or belt-positioning
booster seat in a rear seating position.
3. If a child from 2 to 12 years old (not in a
rear-facing child restraint) must ride in
the front passenger seat, move the seat asWarning Label On Front Passenger Sun
Visor

Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion, a chime will signal for a few seconds. If
the driver or outboard front seat passenger is
unbuckled when the ignition switch is first in
the START or ON/RUN position, the respec-
tive Seat Belt Reminder Light will turn solid
red and remain red until the seat belt is
buckled. The respective Seat Belt Reminder
Light will turn solid green once the seat belt
is buckled. After the driver and outboard front
seat passenger have buckled their seat belts
all Seat Belt Reminder Lights will turn off.
The outboard front passenger seat BeltAlert
is not active when the outboard front passen-
ger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated
when the vehicle is moving above a specified
vehicle speed range and the driver or out-
board front seat passenger is unbuckled (the
outboard front passenger seat BeltAlert is not
active when the outboard front passenger
seat is unoccupied). The BeltAlert warning
sequence starts by blinking the respectiveSeat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warn-
ing sequence has completed, the Seat Belt
Reminder Light will remain solid red until the
driver and outboard front seat passenger are
buckled. The BeltAlert warning sequence
may repeat based on vehicle speed until the
driver and occupied outboard front seat pas-
senger seat belts are buckled. The driver
should instruct all occupants to buckle their
seat belts.
Change of Status
If the driver or outboard front seat passenger
unbuckles their seat belt while the vehicle is
traveling, the BeltAlert warning sequence will
begin until the seat belts are buckled again.
The outboard front passenger seat BeltAlert
is not active when the outboard front passen-
ger seat is unoccupied. BeltAlert may be
triggered when an animal or other items are
placed on the outboard front passenger seat
or when the seat is folded flat (if equipped). It
is recommended that pets be restrained in
the rear seat (if equipped) in pet harnesses or
pet carriers that are secured by seat belts,
and cargo is properly stowed.Rear Seat BeltAlert (If Equipped)
Rear Seat BeltAlert shows the driver whether
the seat belts in the rear seat are buckled or
unbuckled (if equipped with Rear Seat
BeltAlert). When the ignition switch is in the
START or ON/RUN position, a Seat Belt Re-
minder Light
located in the upper right
corner of the instrument cluster turns on for
each second row seat position (if equipped
with Rear Seat BeltAlert). The Rear BeltAlert
warning sequence is activated when the ve-
hicle is moving above a specified vehicle
speed range.
If a second row seat belt is buckled, the Rear
BeltAlert Reminder light for that seating po-
sition will illuminate solid green. If a rear seat
passenger is not wearing the seat belt, the
BeltAlert warning sequence will start (if
equipped with Rear Seat BeltAlert). The re-
spective Seat Belt Reminder light will illumi-
nate solid red. If the seat belt is not buckled
when the vehicle exceeds a specified speed,
the Rear Seat Belt Reminder light will flash
red and a continuous chime will sound for
approximately 30 seconds if there is no
change of status of the rear seat belt buckles.

children are safer when properly restrained in
the rear seats rather than in the front. (Refer
to “Child Restraints” in this section for fur-
ther information.)
