Transmission Messages
SERVICE TRANSMISSION
This message displays when there
is a problem with the transmission.
See your dealer for service.
SHIFT TO PARK
If the vehicle has an automatic
transmission, this message displays
if the vehicle is not in P (Park) when
the engine is being turned off. The vehicle will be in ACCESSORY.
Once the shift lever is moved to
P (Park), the vehicle will turn off.
The vehicle will remain in
ACCESSORY, without the 20 minute
time-out period, until the shift lever
is moved to P (Park) or until the
driver presses the pushbutton to
restart the vehicle. See
Ignition
Positions on page 9‑20 for more
information.
TRANSMISSION HOT IDLE
ENGINE
This message displays and four
chimes sound if the transmission
fluid temperature rises above
132°C (270°F) or rises rapidly.
The transmission may shift gears
or apply the torque converter clutch
to reduce the fluid temperature.
Driving aggressively or driving
on long hills can cause the
transmission fluid temperature to be
higher than normal. If this message
appears, you may continue to drive at a slower speed. Monitor the
transmission fluid temperature and
allow it to cool to at least 110°C
(230°F). The transmission fluid
temperature can be monitored with
the gauges button on the DIC.
See
“DIC Operation and Displays”
under Driver Information Center
(DIC) on page 5‑26 andAutomatic
Transmission Fluid on page 10‑20.
Also check the engine coolant
temperature. If it is also hot, see
Engine Overheating on page 10‑30.
If this message is displayed during
normal vehicle operation on flat
roads, the vehicle may need
service. See your dealer for an
inspection.
If driving in a performance or
competitive manner, the use of
(S) Sport Automatic Mode or
(S) Sport Manual Paddle Shift
gear selection is recommended.
See Automatic Transmission on
page 9‑27 for more information.

See if you can move the shift lever
away from P (Park) without first
pushing the button on the lever.
If you can, it means that the shift
lever was not fully locked into
P (Park).
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 find 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 find out how, see
“Shifting Into P (Park)” 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. See
Jump Starting
on page 10‑78 for more information. To shift out of P (Park) use the
following:
1. Apply the brake pedal.
2. Release the parking brake.
See Parking Brake on
page 9‑36.
3. Press the shift lever button.
4. 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 or a professional towing
service.

Vehicle Care 10-69
Adjust the front and rear tires
to the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated.
SeeTire Pressure on
page 10‑62 andVehicle Load
Limits on page 9‑14.
Reset the Tire Pressure
Monitor System. See Tire
Pressure Monitor Operation on
page 10‑66.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12‑2.{WARNING
Rust or dirt on a wheel, or on
the parts to which it is fastened,
can make wheel nuts become
loose after time. The wheel could
come off and cause an accident.
When changing a wheel, remove
any rust or dirt from places where
the wheel attaches to the vehicle.
In an emergency, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later to remove all rust
or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for
New Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way
to tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. See Tire
Inspection on page 10‑68 andTire
Rotation on page 10‑68 for more
information.

Tightening Wheel Lug Nuts
{WARNING
Never use oil or grease on studs
or the threads of the wheel nuts.
The wheel nuts might come loose
and the wheel could fall off,
causing a crash.
{WARNING
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 specification.
Tighten the wheel lug nuts firmly in
a crisscross sequence.
Tire Chains
{WARNING
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
and road conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage, drive
slowly and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the rear tires.
