WARNING!(Continued)
your vehicle harder to control. You could
have a collision. Have the vehicle checked
immediately.
ELECTRONIC BRAKE
CONTROL SYSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control system (EBC). This
system includes Electronic Brake Force Distri-
bution (EBD), Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Elec-
tronic 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 Hill
Descent Control (HDC).
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 pre-
vent the rear axle from entering ABS before the
front axle.
Brake System Warning LightThe red “Brake System Warning Light” will turn
on when the ignition switch is turned to the ON
position 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 switch is turned to the ON position,
have the light repaired as soon as possible.
Anti-Lock Brake System (ABS)The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The sys-
tem automatically prevents wheel lock, and
enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure
that the ABS is working properly each time the
vehicle is started and driven. During this self-
check, you may hear a slight clicking sound as
well as some related motor noises.
ABS is activated during braking when the sys-
tem detects one or more wheels begins to lock.
Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic
stops may increase the likelihood of ABS acti-
vation(s).
You also may experience the following when
ABS activates:
•The ABS motor noise (it may continue to run
for a short time after the stop).
•The clicking sound of solenoid valves.
•Brake pedal pulsations.

vehicles, people, and objects, and most im-
portantly brake operation to ensure safe
operation of the vehicle under all road con-
ditions. Your complete attention is always
required while driving to maintain safe con-
trol of your vehicle. Failure to follow these
warnings can result in a collision or serious
personal injury.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
WARNING!
•If you use a trailer brake controller with
your trailer, the trailer brakes may be acti-
vated and deactivated with the brake
switch. If so, there may not be enough
brake pressure to hold both the vehicle
and the trailer on a hill when the brake

WARNING!(Continued)
pedal is released. In order to avoid rolling
down an incline while resuming accelera-
tion, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.
•HSA is not a parking brake. Always apply
the parking brake fully when leaving your
vehicle. Also, be certain to leave the trans-
mission in PARK.
•Failure to follow these warnings may
cause the vehicle to roll down the incline
and could collide with another vehicle,
object or person, and cause serious or
fatal injury. Always remember to use the
parking brake while parking on a hill and
that the driver is responsible for braking
the vehicle.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:•For vehicles equipped with the Electronic
Vehicle Information Center (EVIC), refer to
“Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument
Panel” for further information.
•If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Understand-
ing Your Instrument Panel” for further
information.
For vehicles not equipped with the EVIC, per-
form the following steps:
1. Center the steering wheel (front wheels
pointing straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than
one-half turn to the left.
6. Push the “ESC Off” button located in the
lower switch bank below the climate control
190

four times within twenty 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 slighty more than one-half
turn to the right.
8. Turn the ignition switch to the OFF position
and then back to the ON position. 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.
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 drivenaxle is spinning faster than the other, the sys-
tem 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.
Electronic Stability Control (ESC)This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for over-steering or
under-steering of the vehicle by applying the
brake of the appropriate wheel to assist in
counteracting the over-steering or under-
steering condition. Engine power may also be
reduced to help the vehicle maintain the desired
path. ESC uses sensors in the vehicle to deter-
mine 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
over-steer or under-steer condition
•Oversteer - when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.•Understeer - when the vehicle is turning less
than appropriate for the steering wheel
position.
WARNING!
•The Electronic Stability Control (ESC) can-
not 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
hydroplaning. ESC also cannot prevent
collisions resulting from loss of vehicle
control due to inappropriate driver input for
the conditions. Only a safe, attentive, and
skillful driver can prevent collisions.

191

WARNING!(Continued)
•The capabilities of an ESC-equipped ve-
hicle must never be exploited in a reckless
or dangerous manner, which could jeopar-
dize the user’s safety or the safety of
others
•Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle,
and may negatively affect the performance
of the ESC system. Changes to the steer-
ing system, suspension, braking system,
tire type and size or wheel size may ad-
versely affect ESC performance. Improp-
erly inflated and unevenly worn tires may
also degrade ESC performance. Any ve-
hicle modification or poor vehicle mainte-
nance that reduces the effectiveness of the
ESC system can increase the risk of loss
of vehicle control, vehicle rollover, per-
sonal injury and death.ESC Operating Modes
The ESC system has three available operating
modes for four–wheel drive equipped vehicles
and two available operating modes for two–
wheel drive equipped vehicles.
Full On (Four-Wheel Drive Models) Or On
(Two-Wheel Drive Models)
This is the normal operating mode for ESC.
Whenever the vehicle is started, the ESC sys-
tem will be in this “On” mode. This mode should
be used for most driving situations. ESC should
only be turned to “Partial Off” or “ESC Off” for
specific reasons as noted below.
Partial Off (Four-Wheel Drive Models) Or On
(Two-Wheel Drive Models)
This mode is entered by momentarily pushing
the “ESC Off” switch. When in “Partial Off”
mode, the TCS portion of ESC, except for the
“limited slip” feature described in the TCS sec-
tion, has been disabled, and the"ESC OFF
Indicator Light"will be illuminated. All other
stability features of ESC function normally. This
mode is intended to be used if the vehicle is in
deep snow, sand or gravel conditions, and morewheel spin than ESC would normally allow is
required to gain traction.
To turn ESC on again, momentarily push the
“ESC Off” switch. This will restore the normal
“ESC On” mode of operation.
NOTE:
To improve the vehicle’s traction when driv-
ing with snow chains, or starting off in deep
snow, sand or gravel, it may be desirable to
switch to the “Partial Off” mode by pushing
the “ESC Off” switch. Once the situation
requiring ESC to be switched to the “Partial
Off” mode is overcome, turn ESC back on by
momentarily pushing the “ESC Off” switch.
This may be done while the vehicle is in
motion.
WARNING!
When in “Partial Off” mode, the TCS func-
tionality of ESC (except for the limited slip
feature described in the TCS section) has
been disabled and the “ESC Off Indicator
(Continued)
192

WARNING!(Continued)
Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction of
TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is re-
duced. Trailer Sway control (TSC) (if
equipped) is disabled when the ESC system
is in the"Partial Off"mode.
Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or off-
road use when ESC stability features could
inhibit vehicle maneuverability due to trail con-
ditions. This mode is entered by pushing and
holding the “ESC Off” switch for five seconds
when the vehicle is stopped and the engine is
running. After five seconds, the"ESC OFF
Indicator Light"will illuminate and the “ESC
OFF” message will appear in the odometer.
Push and release the Trip Odometer button
located on the instrument cluster to clear this
message.
In this mode, ESC and TCS, except for the
“limited slip” feature described in the TCS sec-tion, are turned off until the vehicle reaches a
speed of 35 mph (56 km/h). At 35 mph
(56 km/h), the system returns to “Partial Off”
mode, as described above. TCS remains off.
When the vehicle speed drops below 30 mph
(48 km/h), the ESC system shuts off. ESC is
deactivated at low vehicle speeds so that it will
not interfere with off-road driving however, ESC
function returns to provide the stability feature
at speeds above 35 mph (56 km/h). The"ESC
OFF Indicator Light"will always be illuminated
when ESC is off.
To turn ESC on again, momentarily push the
“ESC Off” switch. This will restore the “ESC On”
mode of operation.
NOTE:
The “ESC OFF” message will display and an
audible chime will sound when the gear
selector is placed into the PARK position
from any other position, and then moved out
of the PARK position. This will occur even if
the message was previously cleared.
WARNING!
In the"Full Off"mode, the engine torque
reduction and stability features are disabled.
In an emergency evasive maneuver, the
ESC system will not engage to assist in
maintaining stability. “ESC Off” mode is in-
tended for off-highway or off-road use only.
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 igni-
tion switch is cycled to the ON/
RUN position. 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 your authorized
193

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 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 accel-
erator and apply as little throttle as possible. Be
sure to adapt your speed and driving to the
prevailing road conditions.
NOTE:
•The “ESC Off Indicator Light” and the
“ESC Activation/Malfunction Indicator
Light” come on momentarily each time
the ignition switch is placed in the ON/
RUN position.
•Each time the ignition is cycled to the
ON/RUN position, the ESC system will be
ON even if it was cycled off previously,
except for when the vehicle is started
while in 4L Range.•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.
The “ESC OFF Indicator Light” in-
dicates the Electronic Stability
Control (ESC) is partially off or full
off.
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 steer-
ing wheel angle and vehicle’s speed are suffi-
cient 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 preventwheel lift due to other factors, such as road
conditions, leaving the roadway, or striking ob-
jects 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 leav-
ing 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.
194

Run Flat Tires — If EquippedRun Flat tires allow you the capability to drive 50
miles (80 km) at 50 mph (80 km/h) after a rapid
loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A
Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable.
It is not recommended driving a vehicle loaded
at full capacity or to tow a trailer while a tire is in
the run flat mode.
See the tire pressure monitoring section for
more information.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “What To Do In Emergencies”
for further information.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an auto-
matic car wash with a compact or limited-use
temporary spare installed. Damage to the
vehicle may result.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare tire
and wheel equivalent in look and function to the
original equipment tire and wheel found on the
front or rear axle of your vehicle. This spare tire
may be used in the tire rotation for your vehicle.
If your vehicle has this option, refer to an
authorized tire dealer for the recommended tire
rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a compact spare by looking at
the spare tire description on the Tire and Load-
ing Information Placard located on the driver’s
side door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with theletter “T” or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first op-
portunity.
Do not install a wheel cover or attempt to mount
a conventional tire on the compact spare wheel,
since the wheel is designed specifically for the
compact spare tire. Do not install more than one
compact spare tire and wheel on the vehicle at
any given time.
WARNING!
Compact spares are for temporary emer-
gency use only. With these spares, do not
drive more than 50 mph (80 km/h). Tempo-
rary use spares have limited tread life. When
the tread is worn to the tread wear indicators,
the temporary use spare tire needs to be
replaced. Be sure to follow the warnings,
(Continued)
199

WARNING!(Continued)
which apply to your spare. Failure to do so
could result in spare tire failure and loss of
vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary emergency
use only. This tire may look like the originally
equipped tire on the front or rear axle of your
vehicle, but it is not. This spare tire may have
limited tread life. When the tread is worn to the
tread wear indicators, the temporary use full size
spare tire needs to be replaced. Since it is not the
same as your original equipment tire, replace (or
repair) the original equipment tire and reinstall on
the vehicle at the first opportunity.
Limited Use Spare — If EquippedThe limited use spare tire is for temporary emer-
gency use only. This tire is identified by a label
located on the limited use spare wheel. This label
contains the driving limitations for this spare. This
tire may look like the original equipped tire on the
front or rear axle of your vehicle, but it is not.
Installation of this limited use spare tire affects
vehicle handling. Since it is not the same as youroriginal equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle
at the first opportunity.
WARNING!
Limited use spares are for emergency use
only. Installation of this limited use spare tire
affects vehicle handling. With this tire, do not
drive more than the speed listed on the limit
use spare wheel. Keep inflated to the cold
tire inflation pressures listed on your Tire and
Loading Information Placard located on the
driver’s side B-Pillar or the rear edge of the
driver’s side door. Replace (or repair) the
original equipment tire at the first opportunity
and reinstall it on your vehicle. Failure to do
so could result in loss of vehicle control.
Tire SpinningWhen stuck in mud, sand, snow, or ice condi-
tions, do not spin your vehicle’s wheels above
30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping.Refer to “Freeing A Stuck Vehicle” in “What To
Do In Emergencies” for further information.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle’s wheels faster than
30 mph (48 km/h) for more than 30 seconds
continuously when you are stuck, and do not
let anyone near a spinning wheel, no matter
what the speed.
Tread Wear IndicatorsTread wear indicators are in the original equip-
ment tires to help you in determining when your
tires should be replaced.
200

you ever replace a wheel, make sure that the
wheel’s specifications match those of the origi-
nal wheels.
It is recommended you contact your authorized
tire dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replace-
ment tires may adversely affect the safety,
handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size or rating other
than that specified for your vehicle. Some
combinations of unapproved tires and
wheels may change suspension dimen-
sions and performance characteristics, re-
sulting in changes to steering, handling,
and braking of your vehicle. This can
cause unpredictable handling and stress
to steering and suspension components.
You could lose control and have a collision
resulting in serious injury or death. Use
(Continued)
WARNING!(Continued)
only the tire and wheel sizes with load
ratings approved for your vehicle.
•Never use a tire with a smaller load index
or capacity, other than what was originally
equipped on your vehicle. Using a tire with
a smaller load index could result in tire
overloading and failure. You could lose
control and have a collision.
•Failure to equip your vehicle with tires
having adequate speed capability can re-
sult in sudden tire failure and loss of ve-
hicle control.
CAUTION!
Replacing original tires with tires of a differ-
ent size may result in false speedometer and
odometer readings.
TIRE CHAINS (TRACTION
DEVICES)
Use of traction devices require sufficient tire-to-
body clearance. Follow these recommenda-
tions to guard against damage.
•Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
•Install on Front Tires.
•A 215/60R17 96H tire with the use of a
traction device that meets the SAE type
"Class S"specification is recommended.
WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can
cause unpredictable handling. You could
lose control and have a collision.
202

CAUTION!
•The TPMS has been optimized for the
original equipment tires and wheels. TPMS
pressures and warning have been estab-
lished for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. Aftermarket
wheels can cause sensor damage.
•Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle
to an authorized dealership to have your
sensor function checked.
•After inspecting or adjusting the tire pres-
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the TPMS sensor.NOTE:
•The TPMS is not intended to replace nor-
mal tire care and maintenance or to pro-
vide warning of a tire failure or condition.
•The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
•Driving on a significantly under-inflated
tire causes the tire to overheat and can
lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper
tire maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure using an accurate tire gauge,
even if under-inflation has not reached
the level to trigger illumination of the Tire
Pressure Monitoring Telltale Light.
•Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.Base System
This is the TPMS warning indicator
located in the instrument cluster.
The 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 regularly and to maintain the proper
pressure.
The TPMS consists of the following compo-
nents:
•Receiver Module.
•Four Tire Pressure Monitoring Sensors.
•Tire Pressure Monitoring Telltale Light.
