WARNING!(Continued)
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.
ABS is designed to function with the OEM tires. Modifica-
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn on
when the ignition is turned to the ON/RUN mode and
may stay on for as long as four seconds.
If the “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake sys-
tem will continue to operate normally if the “Anti-Lock
Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the benefits of anti-lock brakes. If the “Anti-Lock Brake Warn-
ing Light” does not come on when the ignition is turned to
the ON/RUN mode, have the light repaired as soon as
possible.
Electronic Brake Control System (EBC)
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Electronic Stability
Control (ESC), and Electronic Roll Mitigation (ERM). These
systems work together to enhance both vehicle stability
and control in various driving conditions.
Your vehicle may also be equipped with Ready Alert
Braking (RAB), and Rain Brake Support (RBS).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The sys-
tem 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
5
SAFETY 123

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.
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 capa-
bilities 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.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition is turned to 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 re-
quired. If the “Brake System Warning Light” does not come
on when the ignition is turned to the ON/RUN mode, have
the light repaired as soon as possible.
Electronic Brake Force Distribution (EBD)
This function 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)
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 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.
124 SAFETY

WARNING!(Continued)
Off” mode is only intended for off-highway or
off-road use.
• The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions.
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 turned to the ON 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” (lo-
cated in the instrument cluster) 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.
NOTE:
•
The “ESC Activation/Malfunction Indicator Light” and
the “ESC OFF Indicator Light” come on momentarily
each time the ignition 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 clicking sounds
when it is active. This is normal; the sounds will stop
128 SAFETY

6. Push the “ESC Off” button located in the lower switchbank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Rain Brake Support (RBS)
Rain Brake Support may improve braking performance in
wet conditions. It will periodically apply a small amount of
brake pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers are
in LO or HI speed. When Rain Brake Support is active,
there is no notification to the driver and no driver interac-
tion is required.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to reach
full braking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
monitoring how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.
Traction Control System (TCS)
This system 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 similar 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 torque to be applied to the wheel
that is not spinning. BLD may remain enabled even if TCS
and ESC are in a reduced mode.

SAFETY 131

•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.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. The driver has the respon-
sibility to avoid a collision by controlling the vehicle
via braking and steering. Failure to follow this warn-
ing could lead to serious injury or death.
Turning FCW On Or Off
NOTE: The default status of FCW is on; this allows the
system to warn you of a possible collision with the vehicle
in front of you.
The Forward Collision activation/deactivation is located in
Uconnect Settings underSafety And Driving Assistance.
Forward Collision can be checked or unchecked.
When FCW is selected off, there will be an FCW OFFicon
that appears in the instrument cluster display. Changing the FCW status to off prevents the system from
warning you of a possible collision with the vehicle in front
of you.
NOTE:
The FCW system’s default state is on. The FCW
system state is kept in memory from one ignition cycle to
the next. If the system is turned OFF, it will remain off
when the vehicle is restarted.
Changing FCW Status
The FCW Sensitivity Settings are programmable through
the Uconnect System. Refer to “Uconnect Settings” in
“Multimedia” for further information.
The default status of FCW is the “Far” setting in the “On”
setting. This allows the system to warn you of a possible
collision with the vehicle in front of you when you are
farther away and it applies limited braking. This gives you
the most reaction time to avoid a possible collision.
Changing the FCW status to the “Near” setting, allows the
system to warn you of a possible collision with the vehicle
in front of you when you are much closer. This setting
provides less reaction time than the “Far” setting, which
allows for a more dynamic driving experience.
140 SAFETY

NOTE:
•The system will retain the last setting selected by the
driver after ignition shut down.
• FCW may not react to irrelevant objects such as over-
head objects, ground reflections, objects not in the path
of the vehicle, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.
• FCW will be disabled like ACC, with the unavailable
screens.
Service FCW Warning
If the system turns off, and the instrument cluster display
reads:
• ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
General Information
The following regulatory statement applies to all Radio
Frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and
with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, in- cluding interference that may cause undesired opera-
tion.
NOTE: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
5
SAFETY 141

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 placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
Service Tire Pressure System Warning
If a system fault is detected, the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
instrument cluster will display a Service Tire PressureSystem
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 switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the TPM Telltale Light will no longer flash,
and the Service Tire Pressure System message 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:
• Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
Low Tire Pressure Monitor Display

SAFETY 145

Vehicles With Compact Spare
1. The compact spare tire or non-matching full size doesnot have a tire pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in the compact
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 ignition
key cycle, the “TPMS Telltale 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 and an Inflate to XXmessage.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the instrument cluster will display a “Service
Tire Pressure System” message for five seconds and then
display dashes (- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the
instrument 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 automati-
cally. In addition, the “TPMS Telltale 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 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies 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 (TPM) Sensors. Then, drive the ve-
hicle for 20 minutes above 15 mph (24 km/h). The TPMS
will chime, the Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and then remain
146 SAFETY

on. The instrument cluster will display the “Service Tire
Pressure 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 Tire Pressure 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 TPM
sensors. Then, drive the vehicle for up to 20 minutes above
15 mph (24 km/h). The TPMS will chime, the Tire Pressure
Monitoring System 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 display pressure values in place of the dashes. On the
next ignition cycle theService 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.

SAFETY 147

WARNING!(Continued)
younger, including a child in a rear-facing child
restraint.
• Only use a rear-facing child restraint in the rear seat
of a vehicle with a rear seat.
Seat Belt Systems
Buckle up even though you are an excellent driver, even on
short trips. Someone on the road may be a poor driver and
could cause a collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save lives, and they can
reduce the seriousness of injuries in a collision. Some of the
worst injuries happen when people are thrown from the
vehicle. Seat belts reduce the possibility of ejection and the
risk of injury caused by striking the inside of the vehicle.
Everyone in a motor vehicle should be belted at all times.
Enhanced Seat Belt Use Reminder System (BeltAlert)
Driver and Passenger BeltAlert (if equipped)
BeltAlert is a feature intended to remind the driver
and outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) to buckle their seat belts. The Belt Alert feature is active whenever the
ignition switch is in the START or ON/RUN position.
Initial Indication
If the driver is unbuckled when the ignition switch is first
in the START or ON/RUN position, a chime will signal for
a few seconds. If the driver or outboard front seat passen-
ger (if equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch is first in
the START or ON/RUN position the Seat Belt Reminder
Light will turn on and remain on until both outboard front
seat belts are buckled. The outboard front passenger seat
BeltAlert is not active when an outboard front passenger
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 outboard front seat passenger is unbuck-
led (if equipped with outboard front passenger seat
BeltAlert) (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 Seat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warning sequence
has completed, the Seat Belt Reminder Light will remain on
