If the foot brake fails, pull up and hold the electric parking brake switch to brake the car with the parking brake. The red parking brake indicator flashes while this happens. Let go of the switch to stop emergency braking.
Warning:Use this function with great care in normal driving, and make sure passengers can't press the switch by accident.
Warning:A droning noise during emergency braking is normal.
Warning:Emergency braking slows the car at a fixed rate, which may not match what you want – stopping distances will differ.
Warning:Use it only if the foot brake fails or the pedal is blocked. It can't overcome the limits of tyre grip: on bends, poor roads, in heavy traffic or bad weather the car may skid, slide or pull to one side.
