If there is no curb when you’re parking uphill, turn the
wheels to the right.
If there is no curb when you’re parking uphill on the left
side of a one-way street, your wheels should be turned
to the left.
Torque Lock (Automatic Transaxle)
If you are parking on a hill and you don’t shift your
transaxle into“‘F” (Park) properly, the weight
of the
vehicle may put too much force on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever out of
T“ (Park). This is called “torque lock.” To
prevent torque lock, always be sure to shift into “P”
(Park) properly before you leave the driver’s seat. To
find out how, see “Shifting Into ‘P’ (Park)” in t\
he Index.
When you are ready to drive, move the shift lever out of
“P” (Park) 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 transaxle, so you can pull the shift
lever out of
“P” (Park).

n Now put all the equipment back in the car.
Just follow this drawing:
/! 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 get the right kind.
Stop somewhere as soon as you can and have
the nuts tightened with
a torque wrench. The
torque setting should be
140 N.m (1 00 ft. Ibs.)
Don’t try to put the wheel cover on your compact spare
tire.
It won’t fit. Store the wheel cover in the trunk until
you have the flat tire repaired or replaced.

When to Check: Check your tires once a month or
more.
Don’t forget your compact spare tire. It should be at
60
psi (420 Pa).
How tco Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking at the tires will not
tell you the pressure, especially if
you have radial tires --
which may look~properly inflated even if they’re
underinflated. 1
If your tires have valve caps, be sure to put them back
on. They help prevent leaks~ by keeping out dirt and
moisture.
Tire Inspection and Rotation
To make your tires last longer, have them, inspected and
rotated at the mileages recommended in the
Maintenance Schedule. See “Scheduled Maintenance
Services” in the Index. Use this rotation pattern.
After the tires have been rotated, adjust the
front and
rear inflation pressure as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the
Index.

The proper fluids and lubricants to use are listed in
Section
D. Make sure whoever services your vehicle
uses these. All parts should be replaced and all
necessary repairs done before you or anyone else drives
the vehicle.
NOTE:
To determine your engine’s displacement and
code, see “Engine 1dentific.ation” in the Index.
1. Engine Oil and Filter Change* -- Always use SG
Energy Conserving
I1 oils of proper viscosity. The
“SG, designation may be shown alone or in
combination with others, such as “SG/CC”,
“SG/CD” or “SF,
SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE 5W-30 or SAE 10W-30), see “Engine Oil” in
the Index.

following the instructions in this manual. See “Tires,
Inspection
& Rotation” in the Index, Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check
the wheel alignment. Check
for damaged wheels also.
5. Engine Accessory Drive Belt@) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
6. Cooling System Service* -- Drain, flush and refill
the system with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See
“Coolant” in the Index. This provides proper freeze
protection, corrosion inhibitor level and engine operating temperature.

The U.S. Environmental Protection Agency has determined that the failure to perform this maintenance item will not nullify the emission war\
ranty or limit recall liability prior to the completion of vehicle
useful life. General Motors, however, urges that all recommended maintenance services be performed at the indicated i\
ntervals and the maintenance be recorded in “Section EMaintenance Record”.
