Operation
When you press UNLOCK, the driver’s door will
unlock automatically. If
you press UNLOCK again
within five seconds, all doors will unlock. All doors
will lock when LOCK is pressed. The interior lamps
will come on whenever you lock or unlock
the doors.
See “Keyless Illumination’’
in the Index. Pressing
REAR 2X twice within three seconds, will unlock the
hatch or rear cargo doors.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter
is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with
you when you go to your
dealer. When
the dealer matches the replacement
transmitter
to your vehicle, any remaining transmitters
’ must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have
only two transmitters
matched to it.

Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery
is weak if the transmitter won’t
work at the normal range in any location.
If you have to
get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.
Use one Panasonic@ three volt, type CR2032, or
equivalent battery.
To replace the battery:
1.
2.
Your transmitter housing snaps apart for ease in
battery replacement.
3.
4.
Insert a small coin, or flathead screwdriver, to
separate the bottom of the transmitter from the top.
Remove the battery and replace
it with a new one,
making sure the positive side (+) side of the battery
is facing down.
Snap the top and bottom together.
Test the operation
of the transmitter with your
vehicle. If the transmitter does not work, try
synchronizing the transmitter with the receiver.

To erase all three programmed channels, hold down the
two outside buttons
until the red light begins to flash.
Individual channels cannot be erased, but can be
reprogrammed using the procedure for programming the
transmitter explained earlier.
Training a Garage Opener with a “Rolling
Code” Feature
If you programmed the universal transmitter, but the
garage door will
not open, and if your garage door opener
was manufactured after 1995, your garage door may have
a security feature that changes
the “code” of your garage
door opener every time it is opened or closed.
To determine if your garage door opener has this
“rolling code” feature, press the appropriate button on
the universal transmitter that was programmed. If the
red light flashes rapidly for
one to two seconds, then
turns solid, your garage door opener has this feature.
To program a garage door opener with the rolling code
feature, do
the following:
1. Program your hand-held transmitter to the universal
transmitter by following the steps provided under
“Programming
the Transmitter” earlier in this section.
2.
3.
4.
5.
6.
Remove the cover panel from the garage door opener
receiver.
It is located near the garage door opener motor.
Locate the training button
on the garage door opener
receiver. The exact location and color will vary
among brands.
Press the training button
on the garage door opener
receiver for one to two seconds.
Return to your vehicle and press the programmed
button on the universal transmitter until the red light
flashes rapidly (about two seconds).
Release the button, then press it again
to confirm it
was programmed
to the garage door opener receiver.
You may now use either the universal transmitter or the
hand-held transmitter to open your garage door.
If you
still have difficulty in programming and require
assistance, please call
1-800-355-35 15.
Accessories
Accessories for the universal transmitter are available
from
the manufacturer of the unit. If you would like
additional information, please call

Downloaded from www.Manualslib.com manuals search engine 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
and let anti-lock work for
you. You may feel the brakes
vibrate, or you may notice some noise, but
* ‘.s 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.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control’’ accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws of physics when driving on curves. The
traction
of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there’s no traction, inertia will keep
the vehicle going in the same direction.
If you’ve ever
tried
to steer a vehicle on wet ice, you’ll understand this.
The traction
you can get in a curve depends on the
condition of your tires and the road surface,
the angle at
which the curve is banked, and your speed. While you’re
in a curve, speed is the one Factor you can control.
Suppose you’re steering through
a sharp curve. Then you
suddenly accelerate. Both control systems -- steering and
acceleration
-- have to do their work where the tires meet
the road. Adding the sudden acceleration can demand too much
of those places. You can lose control.

start your left lane change signal before moving out
of the right lane to pass. When you
are far enough
ahead of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back
into the right lane. (Remember that
your right outside mirror is convex. The vehicle
you
just passed may seem to be farther away from you
than
it really is.)
0 Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting
to turn.
If you’re being passed, make it easy for the
following driver to get ahead of you. Perhaps you
can ease a little to the right.
Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and
constantly seek
an escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
“overdriving” those conditions. But skids are
always possible.
The three types
of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
aren’t rolling, In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid, too
much throttle causes
the driving wheels to spin.

I
If you don’t use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured. Pull a trailer ordy if you have followed
all the
steps in this section. Ask your
GM dealer for
advice and information about towing
a trailer
with your vehicle.
NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered
by
your warranty. To pull a trailer correctly, follow
the advice in this part, and see your
GM dealer
for important information about towing a trailer
with your vehicle.
Every vehicle is ready for some trailer towing.
If yours
was built with trailering options,
as many are, it’s ready
for heavier trailers. But trailering
is different than just
driving your vehicle by itself. Trailering means changes
in handling, durability and fuel economy. Successful,
safe trailering takes correct equipment, and
it has to be
used properly.
That’s the reason for this part.
In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers.
So please read this section carefully
before you pull
a trailer.

Downloaded from www.Manualslib.com manuals search engine I A CAUTION:
9. Remove any rust or dirt
from the wheel bolts, mounting surfaces and
spare wheel.
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use
a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
A CAI'TION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall
off, causing a serious accident.
10. Put on the spare tire. Put the nuts on by hand. Make
sure the cone-shaped end
is toward the wheel.
Tighten each
nut by hand until the wheel is held
against the hub.
If a nut can't be turned by hand,
use
the extension and see your dealer as soon
as possible.

Downloaded from www.Manualslib.com manuals search engine Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when
the engine oil is changed.
Change both the fluid and filter every
15,000 miles
(25 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
0 In heavy city traffic where the outside temperature
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
regularly reaches
90 OF (32 ” C) or
higher.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, change the fluid and filter every
30,000 miles
(50 000 km).
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your
GM dealership
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
~ transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which
is 180°F to 200°F
(82°C to 93°C).

Downloaded from www.Manualslib.com manuals search engine Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and
evenly torque wheel nuts in the
proper sequence
to GM specifications.
Your rear drum brakes don’t have wear indicators, but
if
you ever hear a rear brake rubbing noise, have the rear
brake linings inspected. Also,
the rear brake drums
should be removed and inspected each time the tires are
removed for rotation or changing. When
you have the
front brakes replaced, have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection’’ in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.”
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase
in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.
Replacing Brake System Parts
The braking system on a modern vehicle is complex.
Its many parts have to be
of top quality and work well
together if the vehicle is to have really good braking.
Your vehicle was designed and tested with top-quality
GM brake parts. When
you replace parts of your braking
system
-- for example, when your brake linings wear
down and you have to have new ones put
in -- be sure
you get new approved GM replacement parts. If you
don’t, your brakes may
no longer work properly. For
example,
if someone puts in brake linings that are wrong
for your vehicle,
the balance between your front and
rear brakes can change
-- for the worse. The braking
performance you’ve come to expect can change
in many
other ways
if someone puts in the wrong replacement
brake parts.
