Electronic Stability Control (ESC)
The vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the driver
maintain directional control of the vehicle in most driving
conditions.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to ensure
there are no problems. The system may be heard or felt
while it is working. This is normal and does not mean
there is a problem with the vehicle. The system should
initialize before the vehicle reaches 20 mph (32 km/h).
If the system fails to turn on or activate, the ESC/TCS
light comes on, and the ESC OFF and/or SERVICE ESC
message displays.
For more information, seeDriver Information Center
(DIC) on page 3-39andElectronic Stability Control
(ESC)/Traction Control System (TCS) Indicator/Warning
Light on page 3-31.
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 the 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 3-42. This light also
ashes on the instrument panel cluster when the ESC
system is on and activated. A noise may be heard or a
vibration felt in the brake pedal. This is normal. Continue
to steer the vehicle in the intended direction.
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 3-42.
The ESC system is automatically enabled whenever
the vehicle is started. To assist the driver with vehicle
directional control, especially in slippery road conditions,
the system should always be left on. But, ESC can be
turned off if needed.
If cruise control is being used when ESC activates, the
cruise control automatically disengages. The cruise
control can be reengaged when road conditions allow.
SeeCruise Control on page 3-10.

This light ashes while the
traction control system is
limiting wheel spin.
The system may be heard or felt while it is working.
This is normal and does not mean there is a problem
with the vehicle.
SeeElectronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light on page 3-31
for more information.
If the vehicle is in cruise control while TCS begins to
limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. SeeTurn Signal/Multifunction
Lever on page 3-7.
When this light is on and
either the SERVICE
TRACTION or TRACTION
OFF message is displayed,
the system will not limit
wheel spin.Adjust your driving accordingly. SeeDIC Warnings and
Messages on page 3-42for more information.
The Traction Control System comes on automatically
whenever the vehicle is started. It is recommended to
leave the system on for normal driving conditions, but it
may be necessary to turn the system off if the 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 off-road conditions
where high wheel spin is required. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 4-21.
To turn the system off or
on, press and release the
ESC/TCS button located
on the instrument panel.
The DIC displays the appropriate message as described
previously when the button is pressed.

If the ETS indicator/warning light comes on and stays on
for an extended period of time when the transmission
shift lever is in any position other than L (Low), the
vehicle may need service.
When this light is on solid, the system will not limit
wheel spin. Adjust your driving accordingly.
Check the DIC messaging to determine whether it is
because of the driver turning off the system, or that the
system may not be working properly and the vehicle
requires service. When this light is turned on, either the
SERVICE TRACTION or TRACTION OFF message will
be displayed.
SeeDIC Warnings and Messages on page 3-42for more
information on the messages associated with this light.
To limit wheel spin, especially in slippery road conditions,
ETS should always be left on. But the system can be
turned off if needed.
To turn the system off, shift to L (Low) or R (Reverse).When the system is turned off, the ETS indicator/warning
light will come on and stay on and the TRACTION OFF
message will be displayed when the gear shift is in
L (Low). The indicator/warning light and message
will not come on when the gear shift is in R (Reverse).
If the ETS is limiting wheel spin when the transmission is
shifted to L (Low) or R (Reverse) to turn the system off,
the indicator/warning light and TRACTION OFF will come
on in L (Low). But the system will not turn off right away.
It will wait until there is no longer a current need to limit
wheel spin. SeeDIC Warnings and Messages on
page 3-42for more information on the messages
associated with this light.
The system can be turned back on at any time by
shifting to D (Automatic Overdrive) or I (Intermediate).
The ETS indicator/warning light should go off.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
4-11

Also, your dealer/retailer has additives that will help
correct and prevent most deposit-related problems.
Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines might be available in
your area. We recommend that you use these gasolines,
if they comply with the specications described earlier.
However, E85 (85% ethanol) and other fuels containing
more than 10% ethanol must not be used in vehicles that
were not designed for those fuels.
Notice:This vehicle was not designed for fuel
that contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under the vehicle
warranty.
Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasolinewhether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance of
the emission control system could be affected. The
malfunction indicator lamp might turn on. If this occurs,
return to your dealer/retailer for service.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel might be hard
to nd. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel would not be covered by
the vehicle warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you will be driving.

Brake Wear
This vehicle has front disc brakes and could have rear
drum brakes or rear disc brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound can come
and go or be heard all the time the vehicle is moving,
except when applying the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to an
accident. When the brake wear warning sound is
heard, have the vehicle serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates can cause a brake
squeal when the brakes are rst applied or lightly applied.
This does not mean something is wrong with the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to torque specications in
Capacities and Specifications on page 5-108.If the vehicle has rear drum brakes, they do not have
wear indicators, but if a rear brake rubbing noise is heard,
have the rear brake linings inspected immediately. Rear
brake drums should be removed and inspected each time
the tires are removed for rotation or changing. When the
front brake pads are replaced, have the rear brakes
inspected, too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer/retailer if the brake pedal does not
return to normal height, or if there is a rapid increase in
pedal travel. This could be a sign that brake service
might be required.
Brake Adjustment
Every moderate brake stop, the disc brakes adjust for
wear. If rarely making moderate or heavier brake stops,
the brakes might not adjust correctly. Very carefully
making a few moderate brake stops about every
1,000 miles (1 600 km) will adjust the brakes properly.
If the vehicle has rear drum brakes and the brake pedal
goes down farther than normal, the rear drum brakes
might need adjustment. Adjust them by backing up and
rmly applying the brakes a few times.

Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-ination
has not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indicator
is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
ash for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is illuminated, the system
may not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly.
