Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in an accident, the
aim of the headlamps may be affected and adjustment
may be necessary.
If oncoming vehicles ash their high beams at you, this
may mean the vertical aim of your headlamps needs
to be adjusted.
It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be adjusted.
It is possible however, to re-aim the headlamps as
described in the following procedure.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other at
surface.
The vehicle must have all four tires on a level
surface which is level all the way to the wall or other
at surface.
The vehicle should be placed so it is perpendicular
to the wall or other at surface.
The vehicle should not have any snow, ice or
mudonit.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being
performed.
The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs (75 kg)
sitting on the driver’s seat.
Tires should be properly inated.
The spare tire is in its proper location in the vehicle.
Headlamp aiming is done with the vehicle’s low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.

The system can alert you about a low tire — but it does
not replace normal tire maintenance. SeeTires on
page 5-56.
When the tire pressure warning light and the CHECK
TIRE PRESSURE message comes on, you should stop
as soon as you can and check all your tires for
damage. If a tire is at, seeIf a Tire Goes Flat on
page 5-72. Also check the tire pressure in all four tires
as soon as you can. SeeInation - Tire Pressure
on page 5-62.
Any time you adjust a tire’s pressure or have one or
more tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will
also need to reset the system whenever you rotate the
tires, buy new tires, and install or remove the compact
spare tire.
Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires to the
recommended amount. SeeInation - Tire Pressure on
page 5-62. If you reset the system when the tire
pressures are incorrect, the check tire pressure system
will not work properly and may not alert you when a
tire is low or high.To reset (calibrate) the system:
1. Turn the ignition switch to RUN, with the engine off.
2. Press the vehicle information button on the DIC
until the PRESS
VTO RESET TIRE SYSTEM
message appears on the display.
3. Press and hold the DIC Set/Reset button for about
ve seconds. After ve seconds, the display will
show TIRE PRESSURE SYSTEM RESET. If the
TIRE PRESSURE SYSTEM RESET message does
not appear in the display after about ve seconds,
repeat the procedure starting with Step 2. If it does
not work after two tries, see your dealer for service.
The system completes the calibration process during
driving. The system learns the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 20 and 45 minutes of
driving in each of the following speed ranges to learn tire
pressures: 25 to 40 mph (40 to 64 km/h), 40 to 60 mph
(64 to 96 km/h), and 60 to 85 mph (96 to 136 km/h). This
time may be longer depending on your individual driving
habits. Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is reset.

Scheduled Maintenance
When the CHANGE ENGINE OIL SOON message in
the Driver Information Center (DIC) comes on, it means
that service is required for your vehicle. Have your
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the engine oil life
system may not indicate that vehicle service is
necessary for over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your GM
Goodwrench
®dealer has GM-trained service technicians
who will perform this work using genuine GM parts
and reset the system.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-18for information on
the Engine Oil Life System and resetting the system.When the CHANGE ENGINE OIL SOON message
appears, certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst service be
MaintenanceI, your second service be MaintenanceII,
and that you alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceII
may be required more often.
MaintenanceI— Use MaintenanceIif the
CHANGE ENGINE OIL SOON message comes on
within 10 months since the vehicle was purchased or
MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
