2-41 Battery Saver
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave an
interior or trunk lamp on. If you leave any of these
lamps on while the ignition is in ACC or OFF, they will
automatically turn off after 20 minutes. The lamps won't
come back on until you do one of the following:
Turn the ignition to ON,
turn the interior lamp dial all the way up or
open (or close and reopen) a door that is closed.
Please note that if your vehicle has less than 15 miles
(25 km) on the odometer, the battery saver will turn off
the lamps after only three minutes.
Mirrors
Adjust all mirrors so you can see clearly when you are
sitting in a comfortable position.
Inside Day/Night Rearview Mirror
To reduce glare from lamps behind you, push the lever
located on the bottom center of the mirror away from
you to the night position. To return the mirror back to
the day position, pull the lever toward you.
Electrochromic Day/Night Rearview Mirror
with Compass and Map Lamps (If Equipped)
Your vehicle may have an automatic electrochromic
day/night rearview mirror with a compass and map lamps.
This mirror automatically changes to reduce glare from
headlamps behind you. A time delay feature prevents
rapid changing from the day to night positions while
driving under lights and through traffic.

Here are some tips on night driving.
Drive defensively.
Don't drink and drive.
Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
Since you can't see as well, you may need to
slow down and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.
In remote areas, watch for animals.
If you're tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50
-year-old
driver may require at least twice as much light to see the
same thing at night as a 20
-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes will
have less trouble adjusting to night. But if you're driving, don't wear sunglasses at night.
They may cut down on glare from headlamps, but they
also make a lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark.
When you are faced with severe glare (as from a driver
who doesn't lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it's easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and
aren't even aware of it.

CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.

6-34 Headlamps
To replace your headlamps follow these steps:
1. Open the hood.
2. Pull straight up on the two headlamp retainers to
release the assembly locator tabs and take the
retainers off. At the same time, hold the headlamp
assembly in position by applying a little pressure
against the headlamp lens. This prevents the lamp
from falling out.
3. Slide the lamp assembly toward you.

4. Remove the rubber access cover from behind the
bulb you are replacing.
5. Twist and turn the bulb socket counterclockwise and
remove it from the lamp.6. Replace the bulb, making sure you don't touch the
bulb with your bare hands.
7. Reverse all steps and reinstall the headlamp
assembly, then check the lamps.

Headlamp Aiming
Your vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has been
pre
-set at the factory and should need no further
adjustment. This is true even though your vertical and
horizontal aim indicators may not fall exactly on
the ª0º (zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment may be necessary
if it is difficult to see lane markers (for horizontal aim),
or if oncoming drivers flash their high beams at you (for
vertical aim). If you believe your headlamps need to be
re
-aimed, we recommend that you take it to your dealer
for service; however, it is possible for you to re
-aim
your headlamps as described in the following procedure.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
To check the aim, the vehicle should be properly
prepared as follows:
The vehicle must have all four tires on a perfectly
level surface.
If necessary, pads may be used on an uneven surface.
The vehicle should not have any snow, ice or mud
attached to it.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
There should not be any cargo or loading of the
vehicle, except it should have a full tank of fuel and
one person or 160 lbs. (75 kg) on the driver's seat.
Close all doors.
Tires should be properly inflated.
Rock the vehicle to stabilize the suspension.

6-48 Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
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 if any of these conditions exist.
Your dealer 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
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts 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 tire clearance to the body and chassis.
See ªChanging a Flat Tireº in the Index for
more information.
