Downloaded from www.Manualslib.com manuals search engine To lock the power lock system from the outside, insert
the key in the hatch release button and turn it
to the
right. All doors will lock.
Also, see the Caution following “Hatch,” located in
this section.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number
of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there
are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it.
When
you park your vehicle and open the driver’s door,
you’ll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and
so will your
ignition and transmission. And remember to lock
the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember
to keep your valuables out of sight.
Put them in a storage area,
or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it’s best
to lock it up and take your keys.
But what if
you have to leave your key? Do not leave
valuables in your vehicle, since there is no locking area
in which
to secure them. Lock all doors except
the driver’s.
Passlock@
Your vehicle is equipped with the Passlock
theft-deterrent system.
Passlock is a passive theft-deterrent system. The system
is armed once the key is removed from
the ignition.
Passlock enables fuel if the ignition lock cylinder
is
turned with a valid key. If a correct key is not used, fuel
is disabled.
During normal operation, the SECURITY light will go
off after the engine is started.

stops), wait
15 seconds and start over.
When the engine starts, let go
of the key and the
accelerator pedal.
I NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part
of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Fuel Regulator
You have a fuel regulator that shuts the fuel off when the
engine reaches
5,600 rpm.
Engine Coolant Heater (If Equipped)
In very cold weather,
0°F (-18°C) or colder,
the engine coolant heater
can help. You’ll get easier
starting and better
fuel
economy during engine
warm-up. Usually, the
coolant heater should
be
plugged in a minimum of
four hours prior to starting
your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on the
driver’s side
of the engine compartment, near the
power steering fluid reservoir.
3. Plug it into a normal, grounded 110-volt AC outlet.

Downloaded from www.Manualslib.com manuals search engine The anti-lock system can change the brake pressure
faster
than any driver could. The computer is
programmed
to make the most of available tire and
road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly. Remember: Anti-lock doesn’t
change the time you need
to get your
foot up to the brake pedal or always decrease
stopping distance.
If you get too close to the vehicle in
front of you,
you won’t have time to apply your brakes
if
that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work for
you. You may feel the
brakes vibrate, or you may notice some noise, but this
is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.

When you replace your radiator pressure cap, a GM cap
is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow
of coolant through the radiator until the coolant
reaches a preset temperature.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.

Downloaded from www.Manualslib.com manuals search engine How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top
of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten
it. Then remove the cap again and
look at
the fluid level on the dipstick.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up
to the mark.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants” in
the Index.
Always
use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
I Open the cap labeled
WASHER FLUID ONLY.
Add washer fluid until the
tank is full,

Downloaded from www.Manualslib.com manuals search engine Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall).
You sh,ould let your dealer’s service
department
or other qualified service center do these
jobs. Make sure any necessary repairs are completed
nt once.
Proper procedures to perform these services may be
found
in a service manual. See “Service and Owner
Publications’’ in
the Index.
Steering, Suspension and Front Drive Axle
Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack
of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and
then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts
as well as open seams,
holes, loose connections or other conditions which could
cause
a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See “Engine Exhaust’’ in
the Index.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen
or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the outside
of the radiator and air conditioning condenser.
To help
ensure proper operation, a pressure test of the cooling
system and pressure cap is recommended at least once
a year.
