Parking Brake - GMC 2007 Yukon XL Owner's Manual

This will protect the transfer case from possible
damage and will only allow the transfer case to
respond to one shift per 10 seconds. The transfer
case may stay in this mode for up to three minutes.

Parking Brake

To set the parking brake, hold the regular brake
pedal down with your right foot. Push down
the parking brake pedal with your left foot.
A chime will activate and the warning light will
flash when the parking brake is applied and
the vehicle is moving at least 3 mph (5 km/h) for
at least three seconds.
To release the parking brake, hold the regular
brake pedal down. Pull the bottom edge of
the lever, located above the parking brake pedal,
with the parking brake symbol, to release the
parking brake.
If the ignition is on when the parking brake is
released, the brake system warning light will go off.
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.
If you are towing a trailer and are parking on any
hill, see Towing a Trailer on page 405.
