Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift the
transmission into P (Park) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may nd it difficult to pull the
shift lever out of P (Park). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into P (Park) properly before you leave the
driver seat. To nd out how, see “Shifting Into P (Park)”
listed previously in this section.
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 transmission parking pawl, so you
can pull the shift lever out of P (Park).
Shifting Out of Park
Shift lock release prevents shifting out of P (Park)
unless the vehicle is running or in Accessory mode
and the brake pedal is applied.
The shift lock release is always functional except in
the case of an uncharged or low voltage (less than
9-volt) battery. SeeJump Starting on page 5-51
for more information.To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park):
1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift
lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.
Parking the Vehicle
(Manual Transmission)
Before you get out of the vehicle, move the shift lever
into R (Reverse) and rmly apply the parking brake.
Once the shift lever has been placed into R (Reverse)
with the clutch pedal pressed in, you can turn the ignition
off and release the clutch.

Tightening Wheel Lug Nuts
{CAUTION:
Never use oil or grease on studs or the threads
of the wheel nuts. If you do, the wheel nuts might
come loose and the wheel could fall off, causing
a crash.
{CAUTION:
Incorrect wheel nuts or improperly tightened wheel
nuts can cause the wheel to become loose and
even come off. This could lead to a crash. Be sure
to use the correct wheel nuts. If you have to replace
them, be sure to get new GM original equipment
wheel nuts.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 specication.
Tighten the wheel lug nuts
rmly in a crisscross
