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.
A warning chime will sound if the parking brake is
set, the ignition is on, and the vehicle begins to
move. To stop the chime, fully release the
parking brake.
