This feature enables you to stop the vehicle if the main brake system should fail or if the pedal is obstructed.

– Pull out and hold the parking brake switch to stop the vehicle with the parking brake in an emergency.
– The brakes will be released immediately if you release the switch or press down the accelerator.

If you pull out and hold the parking brake switch at a road speed above about 8 km/h, this will initiate an emergency brake application.

The brakes are then applied hydraulically at all four wheels.

The effect is the same as an emergency stop (full brake application) .

To prevent the emergency braking function from being used accidentally, a warning buzzer sounds when the switch is operated. The brakes are released immediately when you release the switch or press down the accelerator.

WARNING

You should only use the emergency braking function in a real emergency, for example if the brake system should fail or if the brake pedal is obstructed. If you use the emergency braking function by activating the parking brake switch, the effect is similar to a full brake application (emergency stop). Please remember that the ESP (with its combined ABS, EDL and traction control functions) is still subject to certain physical limits. In a corner or in bad road or weather conditions an emergency stop can cause the vehicle to skid or lose steering control.
