Parking Brake - Pontiac 2005 GTO Owner's Manual

After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.
Notice: Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
This light will come on when:
•
The engine coolant temperature is higher than
169°F (76°C),
•
you are going 15 to 19 mph (24 to 31 km/h) and
•
you are 21 percent throttle or less.

Parking Brake

To set the parking brake, pull up on the parking brake
handle without pressing the release button. If the ignition
is on, the brake system warning light will come on.
See Brake System Warning Light on page 3-27.
To release the parking brake, hold the regular brake
pedal down. Pull the parking brake handle up until you
can press the release button. Hold the release button
in as you move the brake handle all the way down.
Notice: Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
