is working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop)
• The clicking sound of solenoid valves
• Brake pedal pulsations
• A slight drop or fall away of the brake pedal at the end
of the stop
These are all normal characteristics of ABS.WARNING!
• The Anti-Lock Brake System (ABS) contains so-
phisticated electronic equipment that may be sus-
ceptible to interference caused by improperly in-
stalled or high output radio transmitting
equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
• Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
• The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase braking or steering

efficiency beyond that afforded by the condition of
the vehicle brakes and tires or the traction afforded.
• The Anti-Lock Brake System (ABS) cannot prevent
collisions, including those resulting from excessive
speed in turns, following another vehicle too
closely, or hydroplaning.
• The capabilities of an Anti-Lock Brake System
(ABS) equipped vehicle must never be exploited in
a reckless or dangerous manner, that could jeopar-
dize the user’s safety or the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Warning Light
The “Anti-Lock Brake System (ABS) Warning
Light” monitors the Anti-Lock Brake System. The
light will come on when the ignition switch is turned to
the ON position and may stay on for as long as four
seconds.
If the “ABS 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 system will
continue to operate normally if the “Brake Warning
Light” is not on.
If the “ABS Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
388 STARTING AND OPERATING

does not come on when the ignition switch is turned to
the ON position, have the bulb repaired as soon as
possible.
If both the “Brake Warning Light” and the “ABS Warning
Light” remain on, the ABS and EBD systems are not
functioning. Immediate repair to the ABS system is
required.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
driven wheel. 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), 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 activeeven if TCS and ESC are in the “Partial Off” or “Full Off”
modes. Refer to “Electronic Stability Control (ESC)” in
this section for more information.
Brake Assist System (BAS)
This system complements the ABS by optimizing the
vehicle braking capability during emergency braking
maneuvers. This system detects an emergency braking
situation by sensing the rate and amount of brake appli-
cation and then applies optimum pressure to the brakes.
This can help reduce braking distances.
Applying the brakes very quickly results in the best BAS
assistance. To receive the benefits of this system, you
must apply continuous brake pedal pressure during the
stopping sequence. Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.

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 brak-
ing the vehicle.
HSA Off
If you wish to turn off the HSA system, it can be done in
the Uconnect® Settings. Refer toUconnect® Settingsin
Understanding Your Instrument Panel for further infor-
mation.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for oversteering and understeering the vehicle by applying the brake of the appropriate wheel. Engine
power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESC uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESC applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•
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.

Track Mode
Track Mode is intended to be used when driving on a
track. This raises the threshold for ESC activation further
than Sport and also has track tuned TCS to improve
vehicle performance while on a road course type track.
NOTE:
•To enter Sport ESC mode momentarily push the ESC
Off switch, or use the buttons on the Drive modes
pages in the radio. Pushing the ESC offswitch again
with cycle through to Track ESC mode. Pushing the
ESC off button a third time will bring ESC back to
Street Mode.
• To improve the vehicle’s traction when driving with
snow chains, or when starting off in deep snow, sand,
or gravel, it may be desirable to switch to the “Sport
Mode” by momentarily pushing the “ESC Off” switch. Once the situation requiring “Sport Mode” is over-
come, turn the ESC ON again by momentarily pushing
the “ESC Off” switch. This may be done while the
vehicle is in motion.
WARNING!
When in “Sport/Track” mode, the TCS portion of
ESC, except for the limited wheel spin feature de-
scribed in the TCS section, has been disabled and the
“ESC Off Indicator Light” will be illuminated. When
in “Sport/Track” mode, the enhanced vehicle stabil-
ity offered by the ESC system is reduced.
Full Off
This mode is intended for off-highway or off-road use
only and should not be used on any public roadways. In
this mode, all TCS and ESC stability features are turned
OFF. To enter the “Full Off” mode, push and hold the5

“ESC Off” switch for five seconds while the vehicle is
stopped with the engine running. After five seconds, a
chime will sound, theESC OFF Indicator Light will
illuminate, and the “ESC off” message will appear in the
Driver Information Display (DID). Refer to “Driver In-
formation Display (DID)” in “Understanding Your In-
strument Panel” for further information. To turn ESC ON
again, momentarily push the “ESC Off” switch.
NOTE: TheESC off message will display and the
audible chime will sound when the shift lever is moved
into the PARK position from any position other than
PARK and then moved out of the PARK position. This
will occur when the message was previously cleared.WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
stability. ESC Off mode is intended for off-highway
or off-road use only.

worn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
• Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for

The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warn-
ing (Tire Pressure Monitoring [TPM] Telltale Light) illu-
minates, you must increase the tire pressure to the
recommended cold placard pressure in order for the
“TPM Telltale Light” to turn off. The system will auto-
matically update and the “TPM Telltale Light” will turn
off once the system receives the updated tire pressures.
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.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pressure
of 30 psi (207 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 27 psi (186 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 23 psi (158 kPa). This tirepressure is sufficiently low enough to turn ON the “TPM
Telltale Light”. Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 kPa), but the
“TPM Telltale Light” will still be ON. In this situation, the
“TPM Telltale Light” will turn OFF only after the tires are
inflated to the vehicle’s recommended cold placard pres-
sure value.
CAUTION!
•
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration 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
