has dropped too low, the values
stored in the trip computer will
be lost.
To access trip computer vehicle
data, do one of the following:
Press the BC button on the audio
system.
Press the left thumbwheel, if your
vehicle has this feature, on the

Once an audio function has been
selected, the rows of the trip
computer function are displayed.The functions are displayed in the
following order:
Instantaneous Consumption
This display shows the current fuel
economy at a particular moment
and will change frequently as driving
conditions change. This display
shows the instantaneous fuel
economy in miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
The metric display changes
depending on speed:
Below 8 mph (13 km/h), displays
in l/h.
Above 8 mph (13 km/h), displays
in l/100 km.
This screen cannot be reset.Average Consumption
This display shows the approximate
average miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
This number is calculated based
on the number of mpg (l/100 km)
recorded since the last time this
menu item was reset.
The measurement can be reset to
zero at any time and restarted.
See “Reset” later in this section.

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 8-29.
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system.
The light on the instrument panel
cluster will be on solid to warn
the driver that StabiliTrak is disabled
and requires service. If the problem
does not clear after restarting
the vehicle, you should see your
dealer/retailer for service.The
gswitch is located on the
instrument panel below the Driver
Information Center (DIC).
To turn off StabiliTrak, press and
hold the
gswitch until the light in the
switch illuminates.
To turn StabiliTrak on again, press
the
gswitch again or restart the
vehicle.
A light in the switch should come
on briey when the ignition key
is turned to ON/RUN as a check
to let you know that the light
is working.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3for
more information.
Steering
If the engine stalls while you
are driving, the power steering assist
system should continue to operate
until you are able to stop the
vehicle. If you lose power steering
assist because the 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 power steering system does not
require regular maintenance. If you
suspect steering system problems
and/or the Service Vehicle Soon light
comes on, contact your dealer/
retailer for service repairs.

Power Steering Fluid
When to Check Power
Steering Fluid
It is not necessary to check the
power steering uid level. A power
steering uid leak is the only
reason for uid loss. If a leak
occurs, take your vehicle to the
dealer/retailer service department
and have it repaired as soon
as possible.
Windshield Washer Fluid
What to Use
When you need windshield
washer uid, be sure to read the
manufacturer’s instructions before
use. If you will be operating
your vehicle in an area where the
temperature may fall below freezing,
use a uid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer uid
until the tank is full. SeeEngine
Compartment Overview on page 9-6
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.
