Night Vision
No one can see as well at night as in the daytime. But as we get older these
differences increase.
A SO-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 lights. 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 lights.
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.
Driving in the Rain
Rain and wet roads can mean driving trouble. On a wet road you can’t stop,
accelerate or
turn as well because your tire-to-road traction isn’t as good as
on dry roads. And, if your tires don’t have much tread left, you‘ll get even

Battery
Every new GM vehicle has a Delco Freedom@ battery. You never have to
add water to one of these. When it’s time for a new battery, we recommend
a Delco Freedom@ battery. Get one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more. take off the
black, negative (-) cable from the battery. This will help keep your battery
from running down.
A CAUTION:
Batteries have acid that can burn you and gas that can explod\
e.
You can be badly hurt if you aren’t careful. See “Jump Start\
ing’’
in the Index for tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle for longer storage
periods.

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.
In most cases, you will not need to have your wheels aligned again.
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
GM 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.
A 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/odometer calibration, headlamp
aim, bumper height, vehicle ground clearance, and tire or tire
chain clearance to the body and chassis.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from short circuits by a
combination of fuses, circuit breakers, and fusible thermal links
in the
wiring itself. This greatly reduces
the chance of fires caused by electrical
problems. See “Fuses and Circuit Breakers’’
in the Index for more
information.
Headlamps
The headlamp wiring is protected by a circuit breaker in the lamp switch.
An electrical overload will cause
the lamps to flicker on and off, or in some
cases to remain
off. If this happens, have your headlamp wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by a clrculc DreaKer ana a ruse. 11
the motor overheats due to heavy snow, etc., the wiper will stop until the
motor cools. Although the circuit is protected from electrical overload,
overload due to heavy snow, etc., may cause wiper linkage damage. Always
clear ice and heavy snow from the the windshield before using the
windshield wipers. If the overload
is caused by some electrical problem and
not snow, etc., be sure
to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other
power accessories. When the current load is too heavy, the circuit breaker
opens and closes. This protects the circuit
until the current load returns to
normal or the problem is fixed.
Trailer Wiring Harness
The standard seven-wire trailer wiring harness is protected by an in-line
fuse in the battery feed wire. This fuse is near the junction block. See
“Trailer Wiring Harness” in the Index for more information.
