Electronic Stability Control
In full on mode the TCS system enhances directional
control and stability of the vehicle under various driving
conditions. The ESC corrects for oversteering and under-
steering the vehicle by applying the brake of the appropri-
ate 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.
In full on mode ESC utilizes 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.
WARNING!
The Electronic Stability Control System (ESC) cannot
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 all
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent accidents re-
sulting from loss of vehicle control due to inappropri-
ate driver input for the conditions. Only a safe, atten-
tive, 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.

TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving, and
braking functions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rotation of tires. The
benefits of rotation are especially worthwhile with aggres-
sive tread designs such as those on all season type tires.
Rotation will increase tread life, help to maintain mud,
snow, and wet traction levels, and contribute to a smooth,
quiet ride.
Refer to the “Maintenance Schedule” for the proper main-
tenance interval. Remember, more frequent rotation is
permissible if desired. Also, correct for anything causing
rapid or unusual wear prior to performing the tire rotation.
NOTE:Each wheel on your vehicle contains a tire pressure
sensor. The Tire Pressure Monitor System (TPMS) learns
the location of each sensor though system programming.
Although not required, the manufacturer recommends
reprogramming the TPMS after rotating the tires so that the
system can relearn each sensor ’s location. See your autho-
rized dealer for system reprogramming. The front and rear tires are different sizes and cannot be
used in place of each other. Rotate the tires “side-to-side”
as shown in the diagram.
DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established by the
National Highway Traffic Safety Administration. The specific
grade rating assigned by the tire’s manufacturer in each
category is shown on the sidewall of the tires on your vehicle.
All passenger vehicle tires must conform to Federal safety
requirements in addition to these grades.

TIRE PRESSURE MONITOR SYSTEM (TPMS)
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. 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 TPM sensors.
• Various TPMS messages, which display in the instru-
ment cluster.
• TPM Telltale Light.
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
(7.0 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 after the vehicle has not been driven for at least three
hours, or driven less than 1 mile (1.6 km) after a three hour
period. The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires – General Information” in “Starting And
Operating” for information on how to properly inflate the
vehicle’s tires. The tire pressure will also increase as the
vehicle is driven - this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
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 warning
(Tire Pressure Monitoring [TPM] Telltale Light) illumi-
nates, you must increase the tire pressure to the recom-
mended cold placard pressure in order for the TPM Telltale
Light to turn off. The system will automatically 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.

STARTING AND OPERATING 231

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 tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (158 kPa). This tire pressure is suffi-
ciently low enough to urn 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 pressure 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.
(Continued)
CAUTION! (Continued)
•Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealer to have your sensor function checked.
• After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS 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.
232 STARTING AND OPERATING

•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 TPM Telltale Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Tire Pressure Monitoring Low Pressure Warnings
The TPM Telltale Light will illuminate in the instru-
ment cluster and a chime will sound when tire
pressure is low in one or more of the four active
road tires. In addition, the instrument cluster will display a
LOW TIRE message and a graphic showing the pressure
values of each tire with the low tire pressure values
changing color. An Inflate to XXmessage will also be
displayed.
Should this occur, you should stop as soon as possible and
inflate the tires with a low pressure condition (those in a
different color in the instrument cluster display graphic) to
the vehicle’s recommended cold placard pressure inflation
value as shown in the Inflate to XXmessage. Once the
system receives the updated tire pressures, the system will automatically update, the graphic display in the instru-
ment cluster will change color back to the original color,
and the TPM Telltale Light will turn off. 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 informa-
tion.
Service TPMS 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 TPM SYSTEM
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 TPM 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:
1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors.5
STARTING AND OPERATING 233

2. Installing aftermarket window tinting that contains ma-terials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
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 ve-
hicle. 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 vehicle for 20 minutes above 15 mph (24 km/h). The
TPMS will chime, the “TPM Telltale Light” will flash on
and off for 75 seconds and then remain on and the
instrument cluster will display the “SERVICE TPM SYS-
TEM” message and then display dashes (--) in place of the
pressure values. Beginning with the next ignition switch
cycle, the TPMS will no longer chime or flash the TPM
telltale and display the “SERVICE TPM SYSTEM” message
in the instrument cluster display 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 “TPM Telltale
Light” will flash on and off for 75 seconds and then turn
off, and the instrument cluster will display the “SERVICE
TPM SYSTEM” message. The instrument cluster will also
display pressure values in place of the dashes. On the next
ignition switch cycle the “SERVICE TPM SYSTEM” mes-
sage will no longer be displayed as long as no system fault
exists.
