could begin to move. You or others could be

downhill. Keeping your foot on the regular brake, set the
parking brake.

brake pedal. Do this until the vehicle is held by the
parking brake only.

ability: With the engine running, shift to PARK (P).
Then release the parking brake followed by the
regular brake.

and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear. Do not lubricate accelerator
and cruise control cables.

hoses for proper hook-up, binding, leaks, cracks,
cha®ng, etc. Inspect disc brake pads for wear and rotors

have your brakes inspected more often if your driving
