BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems loses
normal capability, the remaining system will still func-
tion. However, there will be some loss of overall brak-
ing effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light”.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off), the
brakes will still function. However, the effort required
to brake the vehicle will be much greater than that
required with the power system operating.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with a advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Traction
Control System (TCS), Hill Start Assist (HSA), and
Electronic Stability Control (ESC). All systems work
together to enhance vehicle stability and control in
various driving conditions and are commonly referred
to as ESC.
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer
to modulate hydraulic pressure, to prevent wheel
lock-up and to help avoid skidding on slippery sur-
faces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turn-
ing the ignition Off and On again may reset the ABS if
the fault detected was only momentary.

STARTING AND OPERATING 203

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.
• The BAS cannot prevent collisions, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplan-
ing.
• 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.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system, 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. This feature
remains active even if TCS and ESC are in the Partial
Off mode. Refer to “Electronic Stability Control (ESC)”
in this section for further information.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will
maintain the level of brake pressure the driver applied
for a short period of time after the driver takes his foot
off the brake pedal. If the driver does not apply the
throttle during this short period of time, the system will
release brake pressure and the vehicle will roll down
the hill. The system will release brake pressure in
proportion to the amount of throttle applied as the
vehicle starts to move in the intended direction of
travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•
Vehicle must be stopped.
• Vehicle must be on a 2.5% (manual transmission) or
7% grade or greater (automatic transmission) hill.
5
STARTING AND OPERATING 205

•Gear selection matches vehicle uphill direction (i.e.,
vehicle in NEUTRAL (manual transmission), vehicle
facing uphill is in forward gear; vehicle backing
uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer, when the
system will not activate and slight rolling may
occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be
done using the Customer Programmable Features in the
Uconnect Settings. Refer to “Uconnect Settings” in for
further information.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) system enhances
directional control and stability of the vehicle under
various driving conditions. ESC corrects for oversteer-
ing or understeering of the vehicle by applying the
brake of the appropriate wheel to assist in counteracting the oversteering or understeering condition. Engine
power may also be reduced to help the vehicle maintain
the desired path. 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.
•
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 Off Switch (Automatic Transmission)
206 STARTING AND OPERATING

NOTE:The ESC Off switch is located left of the steering
column (Manual Transmission Only).
WARNING!
• The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from acting on
the vehicle, nor can it increase the traction af-
forded by prevailing road conditions. ESC cannot
prevent all accidents, including those resulting
from excessive speed in turns, driving on very

WARNING! (Continued)
slippery surfaces, or hydroplaning. ESC also can-
not prevent collisions resulting from loss of ve-
hicle control due to inappropriate driver input for
the conditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities 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
characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion 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.
ESC Off Switch (Manual Transmission)
5
STARTING AND OPERATING 207

ESC Operating Modes
The ESC system has two available operating modes.
Full On
This is the normal operating mode for ESC. Whenever
the vehicle is started, the ESC system will be in On
mode. This mode should be used for most driving
situations. ESC should only be turned to Partial Off for
specific reasons as noted below.
Partial Off
This mode is entered by momentarily pushing the ESC
Off switch. This mode is intended to be used if the
vehicle is in deep snow, sand or gravel conditions and
more wheel spin than ESC would normally allow is
required to gain traction.
To turn ESC on again, momentarily pushing the switch
again. This will restore the normal ESC On mode of
operation.NOTE:
To improve the vehicle’s traction when driving
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 switch. Once the situation requir-
ing ESC to be switched to the Partial Off mode is
overcome, turn ESC back on by momentarily pushing
the switch. This may be done while the vehicle is in
motion.
WARNING!
• When in “Partial Off” mode, the TCS functional-
ity of ESC, (except for the limited slip feature
described in the TCS section), has been disabled
and the “ESC Off Indicator Light” will be illumi-
nated. 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.

CAUTION!
Because of the reduced ground clearance, do not
take your vehicle through an automatic 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 recom-
mended 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 Loading Information Placard located on
the driver ’s side door opening or on the sidewall of thetire. Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation. Ex-
ample: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original equip-
ment tire should be repaired (or replaced) and rein-
stalled on your vehicle at the first opportunity.
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 and Collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary 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,
which apply to your spare. Failure to do so could
result in spare tire failure and loss of vehicle control.

Collapsible Spare Tire — If Equipped
The collapsible spare is for temporary emergency use
only. You can identify if your vehicle is equipped with
a collapsible spare by looking at the spare tire descrip-
tion on the Tire and Loading Information Placard
located on the driver ’s side door opening or on the
sidewall of the tire.
Collapsible spare tire description example: 165/80-17
101P.
Since this tire has limited tread life, the original equip-
ment tire should be repaired (or replaced) and rein-
stalled on your vehicle at the first opportunity.
Inflate collapsible tire only after the wheel is properly
installed to the vehicle. Inflate the collapsible tire using
the electric air pump before lowering the vehicle.
Do not install a wheel cover or attempt to mount a
conventional tire on the collapsible spare wheel, since
the wheel is designed specifically for the collapsible
spare tire.
WARNING!
Compact and Collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary 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, 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.

STARTING AND OPERATING 225

Limited Use Spare — If Equipped
The limited use spare tire is for temporary emergency
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 your original 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 Plac-
ard 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 Spinning
When stuck in mud, sand, snow, or ice conditions, 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 gener-
ated 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.
