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 awhile.
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.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on the driver's door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle.
It also gives you important
information about the number of people that can be in
your vehicle and the total weight
that you can carry.
This weight is called the vehicle capacity weight and
includes
the weight of all occupants, cargo and aLI
nonfactory-installed options.

Tire Chains
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.
See “Changing a Flat Tire” in the Index for
more information.
Used Replacement Wheels
Putting a used wheel on your vehicle
is
dangerous. You can’t know how it’s been used or
how many miles
it’s been driven. It could fail
suddenly and cause an accident.
Hf you have to
replace a wheel, use a new GM original
equipment wheel.
NOTICE:
If your Pontiac has P235/55R16, P245/50ZRl6 or
P275/40ZR17 size tires, don’t use tire chains.
They can damage
your vehicle.
If you have other tires, use tire chains only where
legal
and only when you must. Use only SAE Class
“S” type chains that are the proper size for your
tires. Install them on the rear tires and tighten
them as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and retighten
them.
If’ the contact continues, slow down until it
stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.

Electrical System Headlamps
Add-on Electrical Equipment
I NOTICE:
Don't add anything electrical to your
Pontiac 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 Pontiac, see "Servicing
Your Air Bag-Equipped Pontiac" in the Index. The
headlamp
wiring is protected by a 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 othei
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.
