Downloaded from www.Manualslib.com manuals search engine Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle
is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can
if your
tires haven’t much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice is to slow down when it
is raining.
Driving Through Deep Standing Water
I
NOTICE:
If you drive too quickly through deep puddles
or standing water, water can come
in through
your engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
0
0 Turn on your low-beam headlamps -- not just
your parking lamps
-- to help make you more
visible to others.
Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and
be prepared to have your view restricted
by road spray.
Have good tires with proper tread depth. (See
“Tires” in the Index.)

Downloaded from www.Manualslib.com manuals search engine 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.
Loading Your Vehicle
The Certificationflire label is found on the rear edge
of the driver’s door. The label shows the size of your
original tires and the inflation pressures needed to obtain
the gross weight capacity your vehicle. This is called
GVWR (Gross Vehicle Weight Rating). The GVWR
includes
the weight of the vehicle, all occupants, fuel
and cargo.

A CAUTION:
Batteries have acid that can burn you ana gas
that can explode. You can be badly hurt if you
aren’t careful. See “Jump Starting” 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.
Also, for your audio system, see “Theft-Deterrent
Feature”
in the Index.
Bulb Replacement
Before you replace any bulbs, be sure that all the lamps
are
off and the engine isn’t running. See “Replacement
Bulbs”
in the index for the proper types of bulbs to use.
Halogen Bulbs
’ A CAUTION: I I
Halogen bulbs have pressurized gas inside and
can burst if you drop
or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.

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.
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.
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.
If you have to
replace
a wheel, use a new GM original
equipment wheel.

Add-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.
Headlamp Wiring
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 Wiper Fuses
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.
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.
