Downloaded from www.Manualslib.com manuals search engine 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.
Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure in
psi (pounds per square inch)
when the engine
is running.
Canadian 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 problems causing
low
oil pressure.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Security Light
This light will come on
briefly when you turn the
The light will stay on until the engine starts.
If the light
flashes, the Passlock” System has entered a tamper
mode.
If the vehicle fails to start, see “Passlock” in
the Index.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
System. Your vehicle will not be protected by Passlock,
and you should see your
GM dealer.

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?
Highway Hypnosis
Is there actually such a condition as “highway
hypnosis”? Or is
it just plain falling asleep at the wheel?
Call
it highway hypnosis, lack of awareness,
or whatever.
There
is something about an easy stretch of road with
the same scenery, along with the hum
of the tires on the
road, the drone of the engine, and the rush of the wind
against the vehicle that can make
you sleepy. Don’t let it
happen to you!
If it does, your vehicle can leave the
road
in less than a second, and you could crash and
be injured.
What can
you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest, service
or parking area and take
a nap, get some exercise, or
both. For safety, treat drowsiness on
the highway as
an emergency.

When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until
it cools down. The
coolant level should be at the
ADD mark.
If it isn’t, you may have
a leak in the radiator hoses,
heater hoses, radiator, water
pump or somewhere else in
the cooling system.

Lift the hood, release the hood prop from its retainer and
put the hood prop into the slot in the hood.
Before closing the hood, be sure all the filler caps
are on
properly. Then lift the hood to relieve pressure on the
hood prop. Remove the

the slot in the hood and
I return the
Drop to its retainer. 1.L
Then just pull the hood
down and close it firmly.
Engine Oil
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.
