Downloaded from www.Manualslib.com manuals search engine Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may
go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank
of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

vehicles indicate pressure in kPa (kilopascals).

Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problem causing low
oil pressure. Check your oil as soon as possible.

Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it

as possible and have your
vehicle serviced.

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. Here
are some things
you can check before a trip:
0
0
Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a
short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?

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.
lhrn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and a heavy-duty turn signal flasher (included in
the optional trailering package).
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 kdh) to reduce the
possibility of engine and transmission overheating.
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 tumine
the engine off. If you do get the overheat warning, see
“Engine Overheating”
in the Index.

You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your
rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK (P) yet. Then turn your wheels into the curb if
facing downhill or into traffic if facing uphill.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes
until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake and then shift to PARK
(P).
Release the regular brakes.
When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
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.

If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel wouldn’t be
covered by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
YOU can also write us at the following address for
advice.
Just tell us where you’re going and give your

Tank (“Diesel Engine)” in the Diesel Engine Supplement.
11 The fuel cap is behind a
hinged door on the driver’s
side of your vehicle.
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.

A CAUTION:
If your vehicle has air conditioning, the auxiliary
engine fan under the hood can start up and
injure
you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
A CAUTION:
I
Things that burn can get on hot engine parts
and start
a fire. These include liquids like
gasoline or diesel fuel, oil, coolant, brake fluid,
windshield washer and other fluids, and plastic
or rubber.
You or others could be burned. Be
careful not
to drop or spill things that will burn
onto
a hot engine.
To open the hood, first
pull this handle inside the
vehicle. It is just
in front of
the driver’s side door frame
near the floor.

Engine Oil (Gasoline Engine)
If your vehicle has a diesel engine, see “Engine Oil
(Diesel Engine)” in the Diesel Engine Supplement.
It’s a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and
the vehicle must be on level ground.

The engine oil dipstick has
a yellow handle and is
located near the center
of
the engine compartment.
Turn
off the engine and
give the oil a few minutes
to drain back into the oil
pan.
If you don’t, the oil
dipstick might not show
the actual level.
