Emergency braking function
This feature enables you to stop the vehicle if the
main brake system should fail or if the pedal is
obstructed
.., To stop the vehicle with the parking brake in an
emergency, pull and hold the parking brake
switch� .
.., The brakes will be released immediately if you
release the switch or press down the accelera­
tor.
If you pull out and hold the parking brake switch
at a road speed above about 3 km/h, this will ini­
tiate an emergency brake application. The brakes
are then applied hydraulically at all four wheels.
The effect is similar to heavy braking
To prevent the emergency braking function from
being used accidentally, a warning buzzer sounds
when the switch is operated. The brakes are re­
leased immediately when you release the switch
or press down the accelerator.
A
WARNING
You should only use the emergency braking
function in a real emergency, for example if
the brake system were to fail or if the brake
pedal were to be obstructed. If you use the
emergency braking function by activating the
parking brake switch, this has the same effect
as heavy braking. Please remember that the
ESC (and the integrated 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 con­
trol.
