I~ ,
Automatic transaxle shift quadrants of all GM vehicles continue the uniform
sequence of
selector positions. Shift indicators are arranged with "P"(Park) position at one end, followed in sequence by "R"(Reverse), "N"(Neutral) and
the forward driving ranges. All automatic transaxles are equipped with a starter
safety switch designed to permit starting the engine
only when the transaxle selector is in the "P"(Park) or "N"(Neutral) position. For additional engine
braking eftect,
as sometimes needed in mountainous driving, place the
transaxle in an intermediate or low range.
Your automatic transaxle has a clutch-type torque converter. The clutch is
designed to engage when the
vehicle reaches a steady speed aibove 25 to 45 mph (40 to 72 km/h). When engaged, the clutch provides a direct connection
between the engine and the drive wheels. This direct connection allows for
more efticient operation of the transaxle and thereby
helps contribute to
improved
fuel economy.
With the clutch-type converter,
you may notice some operational differences
compared to open-type automatic transaxle equipped vehicles. When the
clutch engages, for example, you may notice what feels like an extra transaxle
shift Also, on occasion, you may feel certain incidental engine pulSi'tions in the
30 to 50 mph (50 to 80 km/h) range. This feel is similar to that sometimes
experienced in a manual transaxle equipped vehicle. In addition, when the
accelerator
pedal is released abruptly, you may feel a slight impulse before the
clutch disengages.
These conditions
are normal. They have no adverse effect on your vehicle and
do not indicate the need for repairs.
Notice
The following practices could result in automatic transaxle failure:
• Shifting between forward and reverse driving range while operating the
engine at high speed or heavy throttle, such as when the driving wheels
are on snow or ice--commonly called "rocking." (See the correct method
for
"rocking" a vehicle under "Freeing Vehicle from Sand, Mud, Snow or
Ice" in "In Case of Emergency," Section 3 of this manual.)
•
Shifting to "R"(Reverse) or any forward range while operating the engine
at high speed in "N"(Neutral) or "P"(Park).
•
Shifting to "P"(Park) while the vehicle wheels are still turning.
• Operating the transaxle at or near "stall condition" for more than 1 0 seconds at a time. ("Stall condition" is when the engine is running at high speed while the transaxle is in a driving range and the drive wheels aren't

The parking brake lever is located between the seats .
• To set the parking brake, hold the brake pedal down while pulling the
parking brake
lever all the way up.
• To release the parking brake, hold the brake pedal down while pushing the
button in the tip of the brake
lever and lower the lever. The brake system
warning light is designed to remind you H the parking brake control is not fully released when the ignition is on. Never drive the vehicle with the
parking brake set as this will reduce rear brake effectiveness due to
overheating, shorten brake life, and may cause permanent damege, If
the parking brake does not hold the vehicle securely or does not fully release , see your dealer .
Torque Lock
The perking brake should be set first whenever leaving the driver's seat. If the vehicle is parked on a grade and the transaxle selector lever is placed in "P"
(Park) before the parking brake is set, the weight 01 the vehicle may exert so
much force on the parking pawl in the transaxle that it may be difficult to pull
selector lever out of "P" (Park). This condition Is called "torque lock." To
prevent this, the parking brake should be applied BEFORE moving the selector lever to "P" (Park).
When preparing to move the
Vehicle , the selector lever should be moved out of the "P" (Park) position BEFORE releasing the parking brake. It is good driving
practice to
set the parking brake first. then release the transaxle from "P" (Park), even on level surfaces .
n "torque lock" does oocur, it may be necessary to have another vehicle
nudge this vehicle uphill to take some of the pressure off the transaxle while
the driver pulls on the transaxle selector lever.
CLUTCH PEDAL
On models equipped with a manual transaxle a clutch pedal is used to engage
or disengage the clutch, thereby connecting or disconnecting the engine from
the transaxle and dliveline to the front wheels . When the pedal is fully
extended the clutch is engaged, driving the transaxle and the front wheels .
See "Clutch Adjustment in Section 5 of this manual.

CAUTION: Always securely reatow the, spare tire assembly (or flat tir.), all jacking
equipment, and the cover , using the means provided . When driving the car with the Compact Spare instel~. stow the ",Met COYer in the trunk. In station wagons and hatchbecks, when the rear seat Is folded down, stow the wheel cover nat on the rear floor behind the right front seat. When the r •• r' seat is up, stow the wheel cover in the rear area . This will help keep SUch1tung. trom being thrown about and injuring people during II colhion or • sudden maneuver ..
WHEEL NUT TORQUE
CAUTION:, Never use oil or grease on studs or nuts. Snug all wheel nuta and then tighten to the specified torque In the numerical sequence shown. Improperly tightened wheet nuts coukl eventually alk>w' the wheel to come off while the veh;ckt is 'moving, pOssibly , causing loss of control and/or pertonal injury or damage. As soon as possible after instilling any wheel, have II technician tighten wheel nuts with a torque wrench to the torque Mlown in "Specifications ," Section 6.
(Also see the "Replace ment F~st!3ners" Caution in "Servic e and
Maintenance," Section 5 regarding the danger of mixing metric and customary fasteners . See the "tnspection and Rotation" Caution under "Tires" in the
same section regarding the importance of obtaining
good metal-to-metal
contact.)
Spare Tire
At least monthly, check the spare tire to be sure that it is stowed
securely and properly inflated. If you have a Compact Spare, adjust the
pressure
to 415 kilopascals (60 pounds per square inch). (To find out if you have a COmpact Spare, see "Compact Spare " in this section .) For all other
tires, see "Inflation Pressure"-in Section 5 of this manual to learn what
pressure to use.
Cast Aluminum Wheel Hub Cap
1 . RerJ)ove wheel and tire assemb ly from car.
2 . The hub
cap may be removed by pushing or hitting it away from the wheel
from
the back side (inboard side of wheel) . It is pre ferred that a blunt tool be used on the backside of the hub cap. However, the lug wrench may be
used if no other tool is available but caution must be exercised to avoid hub cap damage .

suggest you purchase a
quality pocket-type gage). Simply looking at the tires to check inflation pressures is not enough, . especially with radial. tires.
Underinflated radial tires may look like correctly inflated radial tires. H the
inflation pressure on a tire is often low, have your dealer correct the
cause.
5. Sesure to put the tire inflation valve caps or extensions back on, if so
equipped. This will help keep dirt and moisture from getting into the valve core which could cause a leak.

6. H an air loss. occurs while driving, do not drive on the flat tire more than is
needed to stop safely. Driving even a short distance on a flat tire can
damage a tire and
wheel beyond repair.
Inspection and Rotation
Front and rear tires perform different jobs and can wear differently depending
on the types of roads driven, your driving habits, etc.
For
longer tire IHe, you shOuld inspect and rotate your tires as recommended in
the Maintenance Schedule folder. Many car and tire dealers will perform a free
tire
inspection to look for \meven or abnormal tire Wear (usually caused by
wrong inflation pressures, lack of regular rotation, improper wheel alignment,
out of bslance tires, or poor driving habits).
After rotation, adjust the front and rear tire pressures (see the Tire
Placard)
and be sure to check wheel nut tightness (see also "Wheel Nut Torque" in
Section 3 of this manual.)
