With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot on
the accelerator. This can really help on long trips. Cruise
control does not work at speeds below about
25 mph
(40km/h).
When you apply your brakes,
the cruise control
shuts
off.
I
Cruise control can be dangerous where you
can’t drive safely at
a steady speed. So,
~ don’t use your cruise control on winding
’ roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could
lose control. Don’t
use cruise control on slippery roads.
Setting Cruise Control
I
I a CA JTION:
If you leave your cruise control switch on
when you’re not using cruise, you might hit a
button and go into cruise when you don’t want
to.
You could be startled and even lose control.
Keep the cruise control switch
OFF until you
want to use it.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press in the SET button
at the end
of the lever
and release
it.
4. Take your foot off the
accelerator pedal.

A tone will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY.
If
you need to use your headlamps when the ignition
switch is in
OFF, LOCK or ACCESSORY, the tone
can be turned off by turning the thumb wheel next
to
the parking lamp/headlamp switch all the way down.
Daytime Running Lamps (If Equipped)
Daytime Running Lamps (Dm) can make it easier for
others
to see the front of your vehicle during the day.
DRL can be helpful
in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset.
The DRL system will make your headlamps come on at
a reduced brightness when:
The ignition is on,
The headlamp switch is off, and
0 The parking brake is released.
If your vehicle was first sold, when new,
in Canada,
your headlamps will come on at reduced brightness.
If your vehicle was first sold, when new, in the United
States, your vehicle may be equipped with DRL.
If your
vehicle has DRL, you
will see the the DRL indicator light
on your instrument panel and your low-beam
headlamps will come on at reduced brightness.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on.
Your instrument panel won’t be lit up either.
When it begins to get dark, your
DRL indicator light is a
reminder to
turn your headlamp switch on. The other lamps
that come on
with your headlamps will also come on.
When
you turn off the headlamp switch, the regular
lamps will go
off, and your headlamps will change to
the reduced brightness of DRL.
To idle your vehicle with the engine on and the DRL off,
set the parking brake. The DRL will stay off until you
release
the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Dome Lamps
The dome lamps will come on when you open the doors.
You can also turn the dome lamps on by rotating the
thumb wheel, located next to the headlamp knob, all
the way up
to the second notch. In this position, the
dome lamps will remain
on whether the doors are
opened or closed.

Downloaded from www.Manualslib.com manuals search engine Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out
in
front of you.
You slam
on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at the
rear wheels. 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 c6mputer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
4-8

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 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.
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.

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.
A cornering skid and an acceleration skid are best
handled by easing your foot off the accelerator pedal.

Towing Your Vehicle
Try to have your GM dealer or a professional towing
service tow your vehicle. They can provide the right
equipment and know-how to tow it without damage.
See “Roadside Assistance’’ in your Index.
If your vehicle has been changed since it was
factory-new, by adding things like fog lamps, aero
skirting, or special tires and wheels, these things could
be damaged during towing.
Before you do anything, turn on the hazard
warning flashers.
When you call, tell the towing service:
That your vehicle has rear wheel drive.
0 The make, model and year of your vehicle.
Whether you can move the shift lever for
the transmission.
If there was an accident, what was damaged.

Downloaded from www.Manualslib.com manuals search engine Engine Fan Noise
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 partially disengages.
You may also hear this fan noise when you start the engine.
It will go away as the fan clutch partially disengages.
If a Tire Goes Flat
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.

Downloaded from www.Manualslib.com manuals search engine Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to
a level place. Turn on your hazard
warning flashers.
a CAUl ION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire
on the other side of the
vehicle,
at the opposite end.
The following steps will tell you how to use the jack and
change
a tire.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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 CAUTION:
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.
8. Replace the wheel nuts
with the rounded end
of
the nuts toward the
wheel. Tighten each
wheel nut by hand until
the wheel is held against
the hub.
9. Lower the vehicle by rotating the jack handle
counterclockwise. Lower the jack completely.

Downloaded from www.Manualslib.com manuals search engine Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does
not mean something is wrong with
your brakes.
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 brake pads 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.
