Downloaded from www.Manualslib.com manuals search engine NEUTRAL (N): In this position, your engine doesn’t
connect with the wheels.
To restart when you’re
already moving,
use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
I
Shifting out of PARK (P) or NEU’I AL (N) while
your engine is “racing” (running at high speed)
is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly.
You could lose control and hit people or
objects. Don’t shift out of PARK (P) or
NEUTRAL
(N) while your engine is racing.
NOTICE:
Damage to your transmission caused by shifting
out of PARK (P) or NEUTRAL
(N) with the
engine racing isn’t covered by your warranty. DRIVE
(D):
This position is for normal driving. If you
need more power for passing, and you’re:
0 Going less than about 35 mph (56 kmk), push your
accelerator pedal about halfway down.
0 Going about 35 mph (56 kdh) or more, push the
accelerator pedal all the way down. You’ll shift
down
to the next gear and have more power.
DRIVE
(D) should be used for normal towing.
THIRD (3): This position is also used for normal
driving, however
it offers more power and lower fuel
economy than DRIVE (D).
You should use THIRD (3)
when carrying a heavy load or driving on steep hills.
SECOND (2): This position gives you more power but
lower
fuel economy. You can use SECOND (2) on hills.
It can help control your speed as
you go down steep
mountain roads, but then
you would also want to use
your brakes
off and on.
If you manually select SECOND
(2), the transmission
will drive in second gear.
You may use this feature
for reducing torque to the rear wheels when you are
trying
to start your vehicle from a stop on slippery
road surfaces.

Downloaded from www.Manualslib.com manuals search engine Torque Lock
If you are parking on a hill and you don’t shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on
the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat. To find out how, see “Shifting Into
PARK
(P)” in the Index.
When
you are ready to drive, move the shift lever out
of PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours
a little uphill to take some of the
pressure from
the parking pawl in the transmission,
so you can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
Your vehicle has a brake-transmission shift interlock.
You have to fully apply your regular brake before
you can shift from PARK (P) when
the ignition is in
the
RUN position. See “Automatic Transmission” in
the Index.
If you cannot shift out
of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear
you want.
If you ever hold the brake pedal down but still can’t
shift out of PARK
(P), try this:
I. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.

counterclockwise. Lower the jack completely.
12. Tighten the wheel nuts
firmly in a criss-cross
sequence
as shown. Turn
the ratchet clockwise with
the
UP mark facing you.
A CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel
to become loose
and even come
off. This could lead to an accident.
Be sure to use the correct wheel nuts.
If you have
to replace them, be sure to get new
GM original
equipment wheel nuts.
Stop somewhere
as soon as you can and have the
nuts tightened with
a torque wrench to 100 lb-ft
(140 Nom).

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
13. Remove the wheel blocks.
I NOTICE:
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover or
the spare.
Storing a Flat or Spare Tire and Tools
Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could
cause injury. In a sudden stop
or collision, loose
equipment could strike someone. Store all these
in the proper place.
1. Put the flat tire on the ground at the rear of the
vehicle, with the valve stem pointed down.
2. Tilt the retaining bar downward and through the
wheel opening. Make sure
it is fully seated across the
underside
of the wheel. Attach the ratchet, with the
UP side facing you, to the extension.

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.

Downloaded from www.Manualslib.com manuals search engine Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
( 10 000 to 1 3 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires’’ and
“Wheel Replacement” later in this section for
more information.
The purpose
of regular rotation is to achieve more
uniform wear
for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your tires, always
use the
correct rotation
pattern shown here.
Don’t include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures
as shown on the
Certificatioflire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque” in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make 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 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. (See
“Changing
a Flat Tire” in the Index.)
