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 q
page
66,
Fig. 74.
� 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 q

.
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.

Hold assist
Applies to vehicles: with hold assist

Section of centre console: Button for hold assist
The hold assist helps the driver if the vehicle is
stationary for a long period or very often, for in

stop-and-go traffic.
Switching on the hold assist
Important: The driver's door must be closed, the

Fig. 75
in the centre console
to switch on the hold assist function. The LED

Stopping with the hold assist
� Once it detects that the vehicle has stopped,
the hold assist keeps the vehicle stationary. You
can now take your foot off the brake pedal.
� Drive off in the normal way: the brake will be
released automatically and the vehicle will start
moving.
Switching off the hold assist
� Press the button to switch off the hold assist
function. The LED in the button will go out.
In certain situations, the hold assist transfers the
job of holding the vehicle to the parking brake. As
soon as the parking brake is holding the vehicle
still, the warning Lamp

appears in the instru
ment cluster.

function cannot defy the Laws of physics. Do
