Parking brake
The parking brake prevents the car from rolling away from stationary by blocking both rear wheels.
A faint electric motor noise can be heard when the electrically-operated parking brake is being applied.
If the car is stationary when the parking brake is activated, it only acts on the rear wheels. If it is activated when the car is moving then the normal foot brake is used, that is, the brake acts on all four wheels. Brake function changes over to the rear wheels when the car is almost stationary.
Note
The driver always bears responsibility for ensuring that the car is parked in a safe manner. Always check that the symbol for parking brake illuminates with a constant glow when parking.
