when you shift into R (Reverse). To release the
parking brake manually, pull the brake release
handle [marked (P)] located on the lower left
corner of the instrument panel. The pedal is now
released and will reset the next time you press
the pedal. The Brake System Warning Light will
glow if the parking brake is not fully released
when the engine is running.
To prevent personal injury, do not release
the parking brake while outside the
vehicle.
Always check the Brake Warning Light each
time you start your engine. Driving with the
parking brake on will cause the brakes to wear
out quickly and will reduce the fuel economy.
If the parking brake is fully released, but
the Brake System light remains on, have
the brakes checked immediately. They
may not be working properly.
The parking brake system is designed for static
parking only and is not designed to stop a
moving vehicle, but you can use the parking
brake to stop your vehicle in an emergency if
the normal brakes fail. However, since the
parking brake applies only the rear brakes, the
stopping distance will increase greatly and the
handling of your vehicle will be adversely
affected.
