Front Axle
It is not necessary to regularly
check front axle uid unless a leak
is suspected or an unusual noise
is heard. A uid loss could indicate
a problem.
It is recommended that the front
axle uid be checked and lled by
your dealer/retailer.
Headlamp Aiming
The vehicle may have a visual
optical headlamp aiming system.
The aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim
may be affected and adjustment
may be necessary.
If oncoming vehicles ash their
high beams at you, this may also
mean the vertical aim needs to
be adjusted.
It is recommended that the vehicle
is taken to your dealer/retailer
for service if the headlamps need to
be re-aimed. It is possible however,
to re-aim the headlamps as
described.The vehicle should be:Placed so the headlamps are
25 ft. (7.6 m) from a light
colored wall or other at surface.
On a level surface which is level
all the way to a wall.
Placed so it is at a right angle to
the wall or other at surface.
Clear of any snow, ice, or
mudonit.
Fully assembled, the tires
properly inated, and all other
work stopped while headlamp
aiming is being performed.
Normally loaded with the spare
tire in its original location and a
full tank of fuel and one person or
160 lbs (75 kg) sitting on the
driver seat.
Service and Appearance Care 5-39

To adjust the vertical aim:
1. Open the hood. SeeHood
Release on page 5-9.
2. Record the distance from the
ground to the aim dot on the
headlamp.3. At a wall, measure from the
ground upward the recorded
distance from Step 2 and mark it.
4. Draw or tape a horizontal line the
width of the vehicle at the wall
where it was marked it Step 4.
Notice:Do not cover a headlamp
to improve beam cut-off when
aiming. Covering a headlamp may
cause excessive heat build-up
which may cause damage to the
headlamp.
5. Turn on the headlamps and
place a piece of cardboard
or equivalent in front of the
headlamp not being aimed.This should allow only the beam
of light from the headlamp being
aimed to be seen on the wall.
6. Locate the vertical headlamp
aiming screws, which are
under the hood near each
headlamp assembly.
The adjustment screw can be
turned with an E8 Torx
®socket
or T15 Torx®screwdriver.

Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer will know the
kind of wheel you need.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one
it replaces.If you need to replace any of your
wheels, wheel bolts, wheel nuts,
or Tire Pressure Monitor System
(TPMS) sensors, replace them only
with new GM original equipment
parts. This way, you will be sure
to have the right wheel, wheel bolts,
wheel nuts, and TPMS sensors
for your vehicle.
{CAUTION
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
on your vehicle can be dangerous.
It could affect the braking and
handling of your vehicle, make
your tires lose air and make you
lose control. You could have a
collision in which you or others
could be injured. Always use the
correct wheel, wheel bolts, and
wheel nuts for replacement.Notice:The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
SeeChanging a Flat Tire on
page 5-66for more information.
Used Replacement Wheels
{CAUTION
Putting a used wheel on the
vehicle is dangerous. You cannot
know how it has been used or how
far it has been driven. It could fail
suddenly and cause a crash. If you
have to replace a wheel, use a
new GM original equipment wheel.
