Your vehicle has power-assisted brakes that adjust automatically through normal usage.
If the engine is not running or is turned off while driving, the power assist for the brakes will not work. You can still stop your vehicle by applying greater force to the brake pedal than typical. The stopping distance, however, will be longer than with power brakes.
When the engine is not running, the reserve brake power is partially depleted each time the brake pedal is applied. Do not pump the brake pedal when the power assist has been interrupted.
Pump the brake pedal only when necessary to maintain steering control on slippery surfaces.
