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 vehicles speed
are sufficient to potentially cause wheel lift, it applies the
appropriate brake and may reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers. ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving maneuvers. It
can not prevent wheel lift due to other factors such as
road conditions, leaving the roadway, striking objects
and/or other vehicles.WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user’s safety or the safety of others.

Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP 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, ESP applies the brake of the appropri-
ate 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.
ESP/TCS Indicator Light
TheESP/TCS Indicator Lightlocated in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. TheESP/TCS Indicator Lightalso
flashes when TCS is active. If theESP/TCS Indicator
Lightbegins 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.
292 STARTING AND OPERATING

Partial Off
This mode is entered by momentarily depressing the ESP
OFF switch (located in the center stack lower switch
bank). When in “Partial Off” mode, the TCS portion of
ESP, except for the “limited slip” feature described in the
TCS section, has been disabled and the “ESP/TCS Indi-
cator Light” will be illuminated. All other stability fea-
tures of ESP function normally. This mode is intended to
be used if the vehicle is in deep snow, sand or gravel
conditions and more wheel spin than ESP would nor-
mally allow is required to gain traction. To turn ESP on
again, momentarily depress the ESP OFF switch. This
will restore the normal “ESP ON” mode of operation.

WARNING!
Temporary use spare tires are for emergency use only.
With these tires, do not drive more than 50 mph
(80 km/h). Temporary use spare tires 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.
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.
Do not install more than one compact spare tire/wheel
on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with the
compact spare installed. Damage to the vehicle may
result.
Limited-Use Spare — If Equipped
The limited-use spare tire is for temporary emergency
use on your vehicle. This tire is identified by a limited-
use spare tire warning label located on the limited-use
spare tire and wheel assembly. 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 tire,
replace (or repair) the original tire and reinstall on the
vehicle at the first opportunity.

WARNING!
The limited-use spare tires are for emergency use
only. Installation of this limited-use spare tire affects
vehicle handling. With this tire, do not drive more
than 50 mph (80 km/h). Keep inflated to the cold tire
inflation pressure listed on either your tire placard or
limited-use spare tire and wheel assembly. Replace
(or repair) the original 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 35 mph (55 km/h).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than
35 mph (55 km/h) when you are stuck, and do not let
anyone near a spinning wheel no matter what the
speed.
310 STARTING AND OPERATING

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 sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
an accident resulting in serious injury or death.
Use only the tire and wheel sizes with load ratings
approved for your vehicle.
•Never use a tire with a smaller load index or
capacity 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 an accident.
(Continued)
WARNING! (Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.

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
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide 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 mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the Tire Pressure Moni-
toring Telltale light.
318 STARTING AND OPERATING

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
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 components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale lightThe matching full-size spare wheel and tire assembly (if
equipped) has a tire pressure monitoring sensor. The
matching full-size spare can be used in place of any of the
four road tires. The TPMS will only monitor the pressure
in the full-size spare when it is used in place of a road
tire. Otherwise, a spare with a pressure below the low-
pressure limit will not cause the Tire Pressure Monitoring
Telltale light to illuminate or the chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale light will illu-
minate in the instrument cluster and a chime will
sound when tire pressure is low in one or more of the
four active road tires. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire on
your vehicle, and inflate each tire to the vehicle’s recom-
mended cold placard pressure value. Once the system
receives the updated tire pressures, the system will auto-
matically update and the Tire Pressure Monitoring Telltale

light will turn off. The vehicle may need to be driven for up
to 20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
Check TPMS Warning
When a system fault is detected, the Tire Pressure Moni-
toring Telltale light will flash on and off for 75 seconds
and then remain on solid. The system fault will also
sound a chime. If the ignition key is cycled, this sequence
will repeat, providing the system fault still exists. The
Tire Pressure Monitoring Telltale light will turn off when
the fault condition no longer exists. A system fault can
occur due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:
Vehicles with Full-Size Spare
1. The matching full-size spare wheel and tire assembly
has a tire pressure monitoring sensor that can be moni-
tored by the TPMS.
2. If you install the full-size spare in place of a road tire
that has a pressure below the low-pressure warning limit,
a chime will sound and the TPMS Telltale light will turn
on upon the next ignition key cycle.
3. Driving the vehicle for up to 20 minutes above 15 mph
(25 km/h) will turn off the TPMS Telltale light, as long as
no tire pressure is below the low-pressure warning limit
in any of the four active road tires.
320 STARTING AND OPERATING

NOTE:
Vehicles with Compact Spare
1. The compact spare tire does not 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 spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, a chime will sound and the TPMS Telltale light will
turn on upon the next ignition key cycle.
3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h), the TPMS Telltale light will flash on
and off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPMS Telltale light will flash on and off
for 75 seconds and then remain on solid.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the TPMS
Telltale light will turn off, as long as no tire pressure isbelow 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 (25 km/h) in order for the
TPMS to receive this information.
