For more information, seeDriver Information
Center (DIC) on page 3-46andElectronic Stability
Control (ESC)/Traction Control System (TCS)
Indicator/Warning Light on page 3-37.
This light ashes on the
instrument panel cluster
when the ESC system
is on and activated.
ESC activates when the computer senses a discrepancy
between your intended path and the direction the vehicle
is actually travelling. ESC selectively applies braking
pressure at any one of the vehicle’s brakes to help steer
the vehicle in the direction which you are steering.
When the system activates, an ESC ACTIVE message
displays on the Driver Information Center. SeeDIC
Warnings and Messages on page 3-48. This light also
ashes on the instrument panel cluster when the
ESC system is on and activated. You may also hear a
noise or feel vibration in the brake pedal. This is
normal. Continue to steer the vehicle in the direction
you want it to go.When the light is on solid and the message(s),
SERVICE ESC, ESC OFF, or both display, the system
will not assist the driver in maintaining directional
control of the vehicle. Adjust your driving accordingly.
SeeDIC Warnings and Messages on page 3-48.
The Electronic Stability Control (ESC) system is
automatically enabled whenever you start your vehicle.
To assist the driver with vehicle directional control,
especially in slippery road conditions, you should always
leave the system on. But, you can turn ESC off if you
ever need to.
If the vehicle is in cruise control when the system
begins to assist the driver maintain directional control of
the vehicle, the ESC/TCS light will ash and the
cruise control will automatically disengage. When road
conditions allow you to use cruise again, you may
re-engage the cruise control. SeeCruise Control on
page 3-12.
The ESC/TCS button
is located on the
instrument panel.
4-11

The traction control system can be turned off or back on
by pressing the ESC/TCS button. To disable both
traction control and ESC, press and hold the button from
ve to ten seconds.
When the ESC system is turned off, the TRACTION
OFF and ESC OFF messages appear, and the
ESC/TCS light comes on to warn the driver that both
traction control and ESC are disabled.
It is recommended that the system remain on for normal
driving conditions, but it may be necessary to turn the
system off if your vehicle is stuck in sand, mud, ice
or snow, and you want to “rock” your vehicle to attempt
to free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions
where high wheel spin is required. SeeIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 4-26.
ESC may also turn off automatically if it determines that
a problem exists with the system. The ESC OFF and
SERVICE ESC messages and the ESC/TCS light comes
on to warn the driver that ESC is disabled and requires
service. If the problem does not clear after restarting
the vehicle, see your dealer/retailer for service. SeeDIC
Warnings and Messages on page 3-48for more
information.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.Competitive Driving Mode
The driver can select this optional handling mode by
pressing the ESC/TCS button on the console two times
within a ve second time period. COMPETITIVE
MODE will be displayed in the DIC. SeeDIC Warnings
and Messages on page 3-48.
Competitive Driving Mode allows the driver to have full
control of the front wheels while the ESC system
helps maintain directional control of the vehicle by
selective brake application. The ESC/TCS light will be
on and the traction control system will not be operating.
Adjust your driving accordingly. This electronic stability
control mode is recommended only for use during closed
track events and competitive driving venues.
When the ESC button is pressed again, or the vehicle is
restarted, the ESC and TCS will be turned back on.
Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the front
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not
attempt to shift when the front wheels do not have
traction. Damage caused by misuse of the vehicle
is not covered. See your warranty book for
additional information.
4-12

Launch Control
If your vehicle has this feature, LAUNCH CONTROL
displays after the COMPETITIVE MODE message, when
the vehicle is stopped. Launch control is a form of
traction control, to control wheel spin while launching
the vehicle during closed track events and competitive
driving venues. The system will exit to COMPETITIVE
MODE after the vehicle is launched. See “Competitive
Driving Mode” earlier in this section. The normal Traction
Control System (TCS) will not be operating while in
the Competitive Driving mode and the TCS light on the
instrument panel cluster comes on. Adjust your
driving accordingly. SeeDIC Warnings and Messages
on page 3-48for more information.
Steering
Electric Power Steering
If the engine stalls while you are driving, the power
steering assist system will continue to operate until you
are able to stop your vehicle. If you lose power
steering assist because the electric power steering
system is not functioning, you can steer, but it will take
more effort.If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time, you
may notice a reduced amount of power steering
assist. The normal amount of power steering assist
should return shortly after a few normal steering
movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems and/or the POWER STEERING message
comes on, contact your dealer/retailer for service
repairs. SeeDIC Warnings and Messages on page 3-48.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.

When replacing the fuel cap, turn it clockwise until
it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the fuel cap has
been left off or improperly installed. This would allow
fuel to evaporate into the atmosphere. SeeMalfunction
Indicator Lamp on page 3-40.
The CHECK GAS CAP message will be displayed on
the Driver Information Center (DIC) if the fuel cap is not
properly installed. SeeDIC Warnings and Messages
on page 3-48for more information.
To close the fuel door securely, push the door to the
closed position.
{CAUTION:
If a re starts while you are refueling, do not
remove the nozzle. Shut off the ow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer/retailer can get one
for you. If you get the wrong type, it may not t
properly. This may cause your malfunction indicator
lamp to light and may damage your fuel tank and
emissions system. SeeMalfunction Indicator Lamp
on page 3-40.

How to Reset the Engine Oil Life System
The Engine Oil Life System calculates when to change
your engine oil and lter based on vehicle use.
Whenever the oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change the oil prior
to a CHANGE OIL SOON message being turned on,
reset the system.
After changing the engine oil, the system must be reset:
1. Turn the ignition to ON/RUN, with the engine off.
2. Press the information and reset buttons on the
Driver Information Center (DIC) at the same
time to enter the personalization menu. SeeDIC
Vehicle Personalization on page 3-54.
3. Press the information button to scroll through the
available personalization menu modes until the
DIC display shows OIL-LIFE RESET.
4. Press and hold the reset button until the DIC
display shows ACKNOWLEDGED. This will tell you
the system has been reset.
5. Turn the key to LOCK/OFF.
If the CHANGE OIL SOON message comes back on
when you start your vehicle, the engine oil life system
has not reset. Repeat the reset procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
lter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have a
problem properly disposing of used oil, ask your
dealer/retailer, a service station, or a local recycling
center for help.
Engine Air Cleaner/Filter
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change after each
50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 6-4for more information.

Tire Pressure Monitor Operation
The Tire Pressure Monitor System (TPMS) is designed
to warn the driver when a low tire pressure condition
exists. If your vehicle has this feature, TPMS sensors
are mounted onto each tire and wheel assembly,
excluding the spare tire and wheel assembly. The TPMS
sensors monitor the air pressure in the vehicle’s tires
and transmits the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS turns on the low tire
pressure warning light
located on the instrument
panel cluster.
At the same time a message to check the pressure in a
specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light
and the DIC warning message come on at each ignition
cycle until the tires are inated to the correct inationpressure. Using the DIC, tire pressure levels can be
viewed by the driver. For additional information
and details about the DIC operation and displays see
DIC Operation and Displays on page 3-46andDIC
Warnings and Messages on page 3-48.
The low tire pressure warning light may come on in
cool weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label shows the size of
your vehicle’s original equipment tires and the correct
ination pressure for your vehicle’s tires when they are
cold. SeeLoading Your Vehicle on page 4-27, for an
example of the Tire and Loading Information label and
its location on your vehicle. Also seeInflation - Tire
Pressure on page 5-60.
Your vehicle’s TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 5-66andTires on page 5-52.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.
5-63

TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
ashes for about one minute and then stays on for
the remainder of the ignition cycle. A DIC warning
message is also displayed. The low tire warning light
and DIC warning message come on at each ignition
cycle until the problem is corrected. Some of the
conditions that can cause the malfunction light and DIC
message to come on are:
One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re-install the road
tire containing the TPMS sensor.
The TPMS sensor matching process was started
but not completed or not completed successfully
after rotating the vehicle’s tires. The DIC message
and TPMS malfunction light should go off once
the TPMS sensor matching process is performed
successfully. See “TPMS Sensor Matching Process”
later in this section.
One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels.
Tires and wheels other than those recommended
for your vehicle could prevent the TPMS from
functioning properly. SeeBuying New Tires on
page 5-69.
Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or
signal a low tire condition. See your dealer/retailer for
service if the TPMS malfunction light and DIC message
comes on and stays on.
