Here are some tips on night driving.
0 Drive defensively.
0 Don’t drink and drive.
0 Adjust your inside rearview mirror to reduce the
glare from he.adlamps behind
you.
0 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.
0 In remote areas, watch for animals.
0 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.

I /1 CAJTION:
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 (or batteries) charged.
You will need a
well-charged battery (or batteries) to restart the vehicle,
and possibly for signaling later
on with your headlamps.
Let the heater run for awhile.
If
you have a diesel engine, you may have to run it at a
higher speed to get enough heat. 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.

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:
I
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.
7
Whenever a wheel, wheel bolt or wheel nut is replaced
on a dual wheel setup, check the wheel
nut torque after
100,
1,000 and 6,000 miles (160, 1 600 and 10 000 km)
of driving. For proper torque, see “Wheel Nut Torque”
in
the Index.
See “Changing a Flat Tire” in the Index for
more information.

Electrical System
Ac . .-On Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle unless
you check with your dealer first. Some electrical
equipment can damage your vehicle and the
damage wouldn’t be covered
by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see “Servicing
Your Air Bag-Equipped Vehicle”
in the Index.
Headlamps
The headlamp wiring is protected by an internal circuit
breaker. An electrical overload
will cause the lamps to
go 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 circuit
breaker and a fuse.
If the motor overheats due to heavy
snow, etc., the wiper will stop
until the motor cools. 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 protect the power windows and other
power accessories. When the current
load is too heavy,
the circuit breaker opens and closes, protecting the
circuit
until the problem is fixed or goes away.
