Electronic Stability Control
Your vehicle may have an Electronic Stability
Control (ESC) system which combines antilock
brake, traction and stability control systems
and helps the driver maintain directional control of
the vehicle in most driving conditions.
When you rst start your vehicle and begin to
drive away, the system performs several diagnostic
checks to ensure there are no problems. You
may hear or feel the system working. This
is normal and does not mean there is a problem
with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h). In
some cases, it may take approximately two
miles of driving before the system initializes.
The ESC light is located
on the instrument panel
cluster.If the system fails to turn on or activate, the ESC
light will be on solid, and the ESC OFF or
SERVICE ESC message will be displayed in the
DIC. If the vehicle has gone through heavy
acceleration or braking during the rst two miles
after starting your vehicle, these messages and the
ESC light may also appear. If this is the case,
your vehicle does not need servicing. Turn your
vehicle off and back on again to reset the system.
If the SERVICE ESC message appears on the
Driver Information Center (DIC), and your vehicle
hasn’t gone through hard acceleration or
braking in the rst two miles, your vehicle should
be taken in for service.
When the ESC off light is on and either the
SERVICE ESC or ESC OFF message is displayed,
the system will not assist the driver to maintain
directional control of the vehicle. Adjust your
driving accordingly. SeeDIC Warnings and
Messages on page 182
The traction control part of ESC can be turned off
or back on by pressing the ESC button. To
disable both traction control and ESC, press and
hold the button briey.

When the system is turned off, the TRACTION
OFF message will rst appear followed by the ESC
OFF message. The ESC OFF and TCS OFF
indicator lights will also appear to warn the driver
that both traction control and ESC are disabled.
It is recommended to leave the system 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 241.
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 OFF light will be on solid to warn the driver
that ESC is disabled and requires service. If
the problem does not clear itself after restarting
the vehicle, you should see your retailer for
service. SeeDIC Warnings and Messages on
page 182.
Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. SeeAccessories
and Modications on page 253.Traction Control Operation
The traction control system is part of the ESC
system. Traction control limits wheel spin by
reducing engine power to the wheels (engine
speed management) and by applying brakes to
each individual wheel (brake-traction control)
as necessary.
The traction control system is enabled
automatically when you start your vehicle, and it
will activate and display the LOW TRACTION
message if it senses that any of the wheels are
spinning or beginning to lose traction while driving.
If you turn off traction control, the TCS OFF
warning light will come on and the TRACTION
OFF message will be displayed The ESC system
will remain operational unless it is turned off.
For more information on the traction active
message, seeDriver Information Center (DIC) on
page 179.

Notice:If you allow the wheel(s) of one axle to
spin excessively while the ESC, ABS and brake
warning lights and the SERVICE ESC message
are displayed, you could damage the transfer
case. The repairs would not be covered by your
warranty. Reduce engine power and do not spin
the wheel(s) excessively while these lights and
this message are displayed.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt
upshifts/downshifts of the transmission. When this
happens, you may notice a reduction in
acceleration, or may hear a noise or vibration.
This is normal.
If your vehicle is in cruise control when the system
activates, the ESC ACTIVE message will appear
and the cruise control will automatically disengage.
When road conditions allow you to use cruise
again, you may re-engage the cruise control. See
Cruise Control on page 145.
ESC may also turn off automatically if it determines
that a problem exists with the system. If the
problem does not clear itself after restarting the
vehicle, you should see your retailer for service.Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. SeeAccessories
and Modications on page 253for more
information.
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, contact your
dealer/retailer for service repairs. SeeDIC
Warnings and Messages on page 182.

While refueling, hang the tethered fuel cap from
the hook on the fuel door.
{CAUTION:
Fuel can spray out on you if you open the
fuel cap too quickly. If you spill fuel and
then something ignites it, you could be
badly burned. This spray can happen if
your tank is nearly full, and is more likely
in hot weather. Open the fuel cap slowly
and wait for any hiss noise to stop. Then
unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon
as possible. SeeWashing Your Vehicle on
page 335.
When replacing the fuel cap, turn it to the right
(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 improperlyinstalled. This would allow fuel to evaporate into
the atmosphere. SeeMalfunction Indicator
Lamp on page 172.
If your vehicle has a Driver Information Center
(DIC), the CHECK GAS CAP message will be
displayed if the fuel cap is not properly installed.
{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.

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change the 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 and lter, the system
must be reset. To reset the oil life system:
1. With the CHANGE OIL SOON message
displayed, press either of the DIC buttons
to clear the CHANGE OIL SOON message.
SeeDIC Warnings and Messages on
page 182.
2. Display OIL LIFE RESET on the DIC.
3. Press and hold the ENTER button for at least
one second. An ACKNOWLEDGED display
message will appear for three seconds or until
the next button is pressed. This will tell you
the system has been reset. SeeDIC Vehicle
Personalization on page 187.
4. Turn the ignition to 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 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.

Adding Washer Fluid
When the windshield washer uid reservoir is low,
a LOW WASHER FLUID message displays on
the Driver Information Center (DIC). SeeDIC
Warnings and Messages on page 182for more
information.
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 264
for reservoir location.Notice:When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill the washer uid tank only
three-quarters full when it is very cold.
This allows for uid expansion if freezing
occurs, which could damage the tank if it is
completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
the vehicle’s windshield washer system
and paint.

Brakes
Brake Fluid
The brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 264for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake hydraulic system. If it is, you should
have the brake hydraulic system xed, since a leak
means that sooner or later the brakes will not
work well.So, it is not a good idea to top off the brake uid.
Adding brake uid will not correct a leak. If
you add uid when the linings are worn, there will
be too much uid when you get new brake
linings. Add or remove brake uid, as necessary,
only when work is done on the brake hydraulic
system.
{CAUTION:
If your vehicle has too much brake uid, it
can spill on the engine. The uid will burn
if the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake hydraulic
system.
When the brake uid falls to a low level, the
BRAKE FLUID message in the Driver Information
Center (DIC) displays. SeeDIC Warnings and
Messages on page 182.

As an added safety
feature, your vehicle
has been equipped with
a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires is
signicantly
under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inate them to the
proper pressure. Driving on a signicantly
under-inated tire causes the tire to overheat and
can lead to tire failure. Under-ination also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
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.
When a low tire pressure condition is detected, the
TPMS illuminates the low tire pressure warning light
on the instrument panel cluster, and at the same
time the CHECK TIRE PRESS message appears
on the Driver Information Center (DIC) display.
