Driving and Operating 9-31
Ride Control Systems
StabiliTrak®System
The vehicle has the StabiliTrak
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 first start the vehicle
and begin to drive away, 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 32 km/h
(20 mph). In some cases, it may
take approximately 3.2 km (2 miles)
of driving before the system
initializes.
If the system fails to turn on or
activate, one of the following
messages will be displayed on theDriver Information Center (DIC):
SERVICE TRACTION CONTROL,
SERVICE STABILITRAK, the
StabiliTrak light will come on
and stay and four chimes are
heard. If these conditions are
observed, turn the vehicle off, wait
15 seconds, and then turn it back
on again to reset the system. If any
of these messages still appear on
the Driver Information Center (DIC),
the vehicle should be taken in for
service. For more information on
the DIC messages, see
Driver
Information Center (DIC) (With DIC
Buttons) on page 5‑25 orDriver
Information Center (DIC) (Without
DIC Buttons) on page 5‑30.
The StabiliTrak light will flash on the
instrument panel cluster when the
system is both on and activated. The system may be heard or felt
while it is working; this is normal.
The traction control button is located
on the instrument panel.
The traction control part of
StabiliTrak can be turned off by
pressing and releasing the traction
control button.
Traction control can be turned
on by pressing and releasing the
traction control button and the
appropriate TRACTION CONTROL
ON message will be displayed, if not
automatically shut off for any other
reason.

It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform
this work and reset the system.
It is also important to check the
oil regularly over the course of
an oil drain interval and keep it
at the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 3,000 miles (5 000 km)
since the last oil change.

10-30 Vehicle Care
Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your dealer
for service.

bulbs, seeReplacement Bulbs on

gas inside and can burst if you
drop or scratch the bulb. You or
