See Section 2 of your Owner Manual.
6-Speed Automatic Transmission
Controls (if equipped)
StabiliTrak®– Stability Control
System (if equipped)
Tire Pressure Monitor
The Tire Pressure Monitor alerts you
when a significant reduction in pressure
occurs in one or more of your vehicle’s
tires by illuminating the (Low Tire
Pressure) warning light on the instru-
ment panel cluster. The low tire pressure
warning light will remain on until you
correct the tire pressure. A CHECK TIRE
PRESSURE message will also appear
on the DIC.
StabiliTrak is an
advanced comput-
er-controlled vehicle
stability and traction
enhancement sys-
tem that assists
with directional control of the vehicle in
difficult driving conditions. It turns on
automatically every time you start your
vehicle.
To limit wheelspin and help maintain
directional control, you should always
leave the system on. However, if your
vehicle becomes stuck and rocking the
vehicle is required, the system should
be turned off.
To turn off the traction control part of
the system, press the (StabiliTrak)
button located below the climate con-
trols on the instrument panel.
To turn off both the traction control and
stability enhancement systems, press
and hold the button for five seconds.
When either system is off, the
StabiliTrak light will illuminate.
See Section 4 of your Owner Manual.

The system is pre-wired from the

See Section 4 of your Owner Manual.

Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must inflate the tire to
the proper tire pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label shows the
correct tire pressure for the tires when
they’re cold. “Cold” means your vehicle
has been sitting for at least three hours
or driven no more than one mile.
You can temporarily clear the DIC
message by acknowledging it with
your DIC controls. However, at the next
vehicle start-up, the DIC message will
reappear if the tire pressure has not
been corrected.
During cooler conditions, the low tire
pressure warning light may appear when
the vehicle is first started and then turn
off as you start to drive. This could be
an early indicator that your tire pres-
sures are getting low and the tires need
to be inflated to the proper pressure.
See Section 5 of your Owner Manual.
Note:The Tire Pressure Monitor can
alert you about low tire pressure, but it
doesn’t replace normal monthly tire
maintenance.
Integrated Trailer Brake Control
System (if equipped)
The control
panel for the
Integrated
Trailer Brake
Control (ITBC)
system is locat-
ed on the
instrument
panel to the left of the steering wheel.If the Tighten Gas Cap message is
displayed on the Driver Information
Center (DIC), check that your fuel cap
is properly installed. If the cap is not
securely fastened, turn it clockwise until
a clicking sound is heard, indicating that
it is properly installed. The DIC message
will turn off after a few driving trips with
the cap properly installed.
See Sections 3 and 5 of your Owner Manual.
Tighten Gas Cap Message
If your vehicle has a yellow gas cap, it
was engineered as a FlexFuel vehicle
capable of running on gasoline or E85
fuel. E85 is a blend of 85% ethanol and
15% gasoline. E85 is a high-octane,
renewable fuel made primarily from corn
(see livegreengoyellow.com).
FlexFuel (E85) – Yellow Gas Cap
(if equipped)
Note:If the trailer brakes are manually
applied, the brake lights do not turn on.

Your FlexFuel vehicle automatically
detects the current fuel mixture in the
fuel tank and adjusts engine settings
accordingly. You can fill up with gasoline
or E85, regardless of which fuel is
already in the tank.
E85 is not yet available at all gas sta-
tions. E85 holds less energy per gallon
than gasoline, so drivers will experience
lower miles per gallon and cruising
range when running on E85.
See Section 5 of your Owner Manual.
23
Note: If your vehicle does not have the
yellow gas cap, do not use E85.
The Oil Life System calculates engine oil
life based on vehicle use and displays
CHANGE ENGINE OIL SOON on the
Driver Information Center (DIC) when it’s
necessary to change your engine oil and
filter. The Oil Life System should be
reset to 100% only following an oil
change.
To reset the Oil Life System:
1. Turn on the ignition.
2. Press the (Vehicle Information)
button until the DIC displays OIL LIFE
REMAINING.
3. Press and hold the (Set/Reset)
button until 100% is displayed.
4. Turn off the ignition.
