Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle
could move suddenly if the shift lever is
not fully in PARK (P) with the parking
brake rmly set.
If you have four-wheel drive, your vehicle
will be free to roll – even if your lever is in
PARK (P) – if your transfer case is in
NEUTRAL. So be sure the transfer case is
in a drive gear – not NEUTRAL. See
Four-Wheel Drive on page 122.
And, if you leave the vehicle with the
engine running, it could overheat and
even catch re. You or others could be
injured. Do not leave your vehicle with the
engine running unless you have to.If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. After you have moved the shift lever into
PARK (P), hold the regular brake pedal down.
Then, see if you can move the shift lever
away from PARK (P) without rst pressing the
button on the console shift lever. If you can,
it means that the shift lever was not fully locked
into PARK (P).

Service Four-Wheel Drive
Warning Light
This light should come
on briey when you turn
on the ignition, as a
check to show you
it is working.
The service four-wheel drive light comes on to
indicate that there may be a problem with the drive
system and service is required. Malfunctions
can be indicated by the system before any problem
is apparent, which may prevent serious damage
to the vehicle. This system is also designed
to assist your dealer in correctly diagnosing a
malfunction.
Check Gages Warning Light
The check gages light
will come on briey
when you are starting
the engine.
If the light comes on and stays on while you are
driving, check your coolant temperature and
engine oil pressure gages to see if they are in the
warning zones.
Gate Ajar Light
If this light comes on,
the liftgate or liftglass is
not completely shut.
Close the liftgate or liftglass. Never drive with the
liftgate or liftglass even partially open.
216

DIC Operation and Displays
The DIC comes on when the ignition is on. After a
short delay the DIC will display the information
that was last displayed before the engine
was turned off.
If a problem is detected, a warning message will
appear on the display. Pressing the trip stem
will acknowledge any warning or service
messages. Pressing any of the DIC steering wheel
buttons — trip information, fuel information,
customization, or select button — will also
acknowledge any warnings or service messages.
You should take any message that appears on
the display seriously and remember that clearing
the message will only make the message
disappear, not correct the problem.
The DIC has different modes which can be
accessed by pressing the four DIC buttons located
on the steering wheel. These buttons are trip
information, fuel information, customization, and
select. The button functions are detailed in
the following pages.
Trip Information Button
3
(Trip Information):Press the trip
information button to scroll through the
ODOMETER, TRIP A, TRIP B, TIRE
PRESSURES, and TIMER.
Odometer:Press the trip information button until
ODOMETER appears on the display. This
mode shows the total distance the vehicle has
been driven in either miles or kilometers. Pressing
the reset stem located on the instrument cluster
with the vehicle off will also display the odometer.
Trip A:Press the trip information button until
TRIP A appears on the display. This mode shows
the current distance traveled since the last
reset for TRIP A in either miles or kilometers.
Trip B:Press the trip information button
until TRIP B appears on the display. This mode
shows the current distance traveled since the last
reset for TRIP B in either miles or kilometers.

SERVICE TIRE MONITOR
This message displays if a part on the Tire
Pressure Monitor (TPM) system is not working
properly. If you drive your vehicle while any of the
four sensors are missing or inoperable, the
warning comes on in about 20 minutes. A sensor
would be missing, for example, if you put
different wheels on your vehicle without
transferring the sensors. If the warning comes on
and stays on, there may be a problem with the
TPM. See your dealer.
STABILITRAK ACTIVE
This message displays anytime the StabiliTrak®
system activates to maintain vehicle stability.
Any combination of engine speed management,
brake traction control, and stability control displays
this message.
STABILITRAK NOT READY
This message may display if driving conditions
delay StabiliTrak®system initialization. This
is normal. Once the system initializes, this
message will no longer be displayed on the DIC.
STABILITRAK OFF
This message displays when you press the
StabiliTrak®button for more than ve seconds or
when stability control has been automatically
disabled. The StabiliTrak
®button is located on the
transmission shift handle. To limit wheel spin and
realize the full benets of the stability enhancement
system, you should normally leave StabiliTrak
®on.
However, you should turn StabiliTrak®off if your
vehicle gets stuck in sand, mud, ice, or snow and
you want to rock your vehicle to attempt to free it, or
if you are driving in extreme off-road conditions and
require more wheel spin. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 348.
To turn the StabiliTrak
®system back on, press the
StabiliTrak®button again.

Off-Road Driving
This off-road guide is for vehicles that have
four-wheel drive. Also, seeBraking on page 306.If
your vehicle does not have four-wheel drive, you
should not drive off-road unless you are on a level,
solid surface.
Off-road driving can be great fun. But it does have
some denite hazards. The greatest of these is
the terrain itself.
“Off-roading” means you have left the great North
American road system behind. Traffic lanes
are not marked. Curves are not banked. There
are no road signs. Surfaces can be slippery, rough,
uphill, or downhill. In short, you have gone right
back to nature.
Off-road driving involves some new skills. And that
is why it is very important that you read this guide.
You will nd many driving tips and suggestions.
These will help make your off-road driving safer and
more enjoyable.
Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary
maintenance and service work done. Check to
make sure all underbody shields, if the vehicle has
them, are properly attached.
Be sure you read all the information about your
four-wheel-drive vehicle in this manual.
Is there enough fuel? Is the spare tire fully inated?
Are the uid levels up where they should be? What
are the local laws that apply to off-roading where
you will be driving? If you do not know, you should
check with law enforcement people in the area. Will
you be on someone’s private land? If so, be sure to
get the necessary permission.
