Downloaded from www.Manualslib.com manuals search engine Stalling on an Incline
If your vehicle stalls when you’re crossing an incline, be
sure you (and your passengers) get out on the uphill
side, even if the door there is harder to open. If you get
out
on the downhill side and the vehicle starts to roll
over, you’ll be right in its path.
If you have to walk down the slope, stay out of the path
the vehicle will take
if it does roll over.
Getting out on the downhill (low) side of a vehicle
stopped across an incline
is dangerous. If the
vehicle rolls over, you could be crushed or killed.
Always get out on the uphill (high) side
of the
vehicle and stay well clear
of the rollover path.
Driving in Mud, Sand, Snow or Ice
When you drive in mud, snow or sand, your wheels won’t get
good traction. You can’t accelerate as quickly, turning is
more difficult, and you’ll need longer braking distances.
It’s best to use a low gear when you’re in mud
-- the
deeper the mud, the lower the gear. In really deep mud,
the idea
is to keep your vehicle moving so you don’t
get stuck.
When you drive on sand, you’ll sense a change in wheel
traction. But it will depend upon how loosely packed the
sand is. On loosely packed sand (as on beaches or sand
dunes) your tires will tend to sink into the sand. This has
an effect
on steering, accelerating and braking. You may
want
to reduce the air pressure in your tires slightly
when driving on sand. This will improve traction.

Downloaded from www.Manualslib.com manuals search engine Hard packed snow and ice offer the worst tire traction.
On these surfaces, it’s very easy to lose control. On wet
ice, for example, the traction is
so poor that you will
have difficulty accelerating. And if
you do get moving,
poor steering and difficult braking can cause you to slide
out of control. through.
Also, water that deep can damage your axle
and other vehicle parts.
If the water isn’t too deep, then drive through it slowly. At
fast speeds, water splashes on your ignition system and
your vehicle can stall. Stalling can
also occur if you get
your tailpipe under water. And, as long as your tailpipe
is
under water, you’ll never be able to start your engine.
When you
go through water, remember that when your
brakes get wet, it may take you longer to stop.

Driving on frozen lakes, ponds or rivers can be
dangerous. Underwater springs, currents under
the ice, or sudden thaws can weaken the ice. Your
vehicle could fall through the ice and you and
your passengers could drown. Drive your vehicle
on safe surfaces only.
Driving in Water
Light rain causes no special off-road driving problems.
But heavy rain can mean flash flooding, and flood
waters demand extreme caution.
Find out how deep the water is before you drive through
it. If it’s deep enough to cover your wheel hubs, axles or
exhaust pipe, don’t
try it -- you probably won’t get
A CAUTION:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
See “Driving Through Water” in the Index for more
information on driving through water.

mt
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 less traction. It’s always wise to go slower and be
cautious if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving on dry pavement.
The heavier the rain, the harder it is to see. Even if your
windshield wiper blades are in good shape, a heavy rain
can make it harder to see road signs and traffic signals,
pavement markings, the edge
of the road and even
people walking.
It’s wise to keep your wiping equipment in good shape
and keep your windshield washer tank filled with
washer fluid. Replace your windshield wiper inserts
when they show signs of streaking or missing areas on
the windshield, or when strips
of rubber start to separate
from the inserts. I

Downloaded from www.Manualslib.com manuals search engine The most important advice on freeway driving is: Keep
up with traffic and keep to the right. Drive at the same
speed most of the other drivers are driving. Too-fast or
too-slow driving breaks a smooth traffic flow. Treat the
left lane on a freeway
as a passing lane.
At the entrance, there is usually a ramp that leads to the
freeway. If you have
a clear view of the freeway as you
drive along the entrance ramp, you should begin to
check traffic. Try to determine where you expect to
blend with the flow. Try to merge into the gap at close to
the prevailing speed. Switch on your turn signal, check
your mirrors and glance over your shoulder as often as
necessary. Try to blend smoothly with the traffic flow.
Once you
are on the freeway, adjust your speed to the
posted limit or to the prevailing rate if it’s slower. Stay
in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before
you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
Once you are moving on the freeway, make certain
you
allow a reasonable following distance. Expect to move
slightly slower at night. When
you want to leave
the freeway, move to the proper
lane well in advance. If you miss your exit, do
not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than
you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re
not fresh -- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have
it done before starting out. Of course,
you’ll find experienced and able service experts in
GM
dealerships all across North America. They’ll be ready
and willing to help if you need it.

NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal.
Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even
if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 kmh) to reduce the
possibility of engine and transmission overheating.
If you have an automatic transmission, you can tow
in
AUTOMATIC OVERDRIVE (0). You may want to
shift the transmission to THIRD
(3) or, if necessary, a
lower gear selection if the transmission shifts too often
(e.g., under heavy loads and/or hilly conditions).
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. If you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar
to engine overheating. To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK
(P) for a few
minutes before turning the engine off. If you do get the
overheat warning, see “Engine Overheating” in
the Index.

Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help you find them quickly.
If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
A seven-wire harness is stored under the rear of your
vehicle, between the frame rails. An electrical connector
will need to be added at the trailer end
of the harness, by
a qualified electrical technician. For additional trailer
wiring and towing information, please consult your
dealer. Securely attach the harness to the trailer, then
tape or strap it to your vehicle’s frame rail. Be sure you
leave it loose enough
so the wiring won’t bind or break
when turning with the trailer, but not
so loose that it
drags on the ground. Store the harness in its original
position. Wrap the harness together and tie it neatly
so it
won’t be damaged. If you tow a trailer, your Center
High-Mounted Stoplamp (CHMSL) may not be
properly visible from behind. You should select a trailer
with a CHMSL
on it or, if one is not available, have one
installed. See your GM dealer about how to connect
your vehicle’s wiring to
a trailer CHMSL.

Downloaded from www.Manualslib.com manuals search engine Engine Fan Noise If a Tire Goes Flat
Your vehicle has a clutched engine cooling fan. When
the clutch is engaged,
the fan spins faster to provide
more air to cool the engine.
In most everyday driving
conditions, the fan is spinning slower and the clutch is
not fully engaged. This improves fuel economy and
reduces fan noise. Under heavy vehicle loading, trailer
towing and/or high outside temperatures, the fan speed
increases as the clutch more fully engages.
So you may
hear an increase
in fan noise. This is normal and should
not be mistaken as the transmission slipping or making
extra shifts. It is merely the cooling system functioning
properly. The fan will slow down when additional
cooling is not required and the clutch disengages.
You may also hear this fan noise when you start the
engine. It will go away as the fan clutch disengages. It’s
unusual for a tire to “blow out’’ while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a
few tips about what to expect and what
to do:
If
a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your
foot off
the accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then’ gently brake to
a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in
a skid. In any rear blowout, remove your foot from
the accelerator pedal. Get the vehicle under control
by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how
to use your
jacking equipment to change a flat tire safely.
