Leaving Your Vehicle With the Engine
Running (Automatic Transmission
Models Only)
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move suddenlJ
if the shift lever
is not fully in PARK (P) with the
parking brake firmly set. If you have four-wheel
drive with
a manual transfer case shift lever and
your transfer case
is in NEUTRAL (N), your
vehicle will
be free to roll, even if your shift lever
is in
PARK (P). So be sure the transfer case is in a
drive gear
-- not in NEUTRAL (N). And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave
your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle
is in PARK (P) and yo~~r parking brake
is firmly set before you leave
it. After
you've moved the shift lever into the PARK
(P)
position, hold the regular brake pedal down. Then, see
if you can move the shift lever away from PARK (P)
without first pulling it toward you (or pressing the
button on
a console shift lever). If YOLI can, it means that
the shift lever wasn't fully locked
into PARK (P).
Torque Lock (Automatic Transmission)
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 br'ke 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) kc$~w 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
~OLI can pull the shift lever out of PARK (P).

Storing a Flat or Spare Tire and Tools
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 yo11 have
to replace them, be sure to get new GILI original
equipment wheel nuts.
Stop somewhere as soon
as you can and have the
nuts tightened with
a torque wrench to 95 Ib-ft
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
' A CAUTION:
-
Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could
cause in,jury. In
a sudden stop or collision, loose
equipment could strike someone. Store
all these
in the proper place.
NOTICE:
An aluminum wheel with a flat tire should always
be stored under the vehicle with the hoist.
However, storing it that way
for an extended
period could damage the wheel.
To avoid this,
have the wheel repaired as soon as possible.

Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
If you have the all-wheel drive option, your vehicle has
four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a
high-pitched warning sound when the brake pads are worn
and new pads are needed.
The sound may come and go or
be heard all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
I A CAUTION: I
The brake wear warning sound means that soon
your brakes won't
work well. That could lead to
an accident. When you hear the brake wear
warning
sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
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."

I1
If your vehicle has a compact spare tire, don’t include it
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.)
