XDS works in combination with the ESC and is
always active, even when TCS is switched off,
or when the ESC is in Sport mode or discon-
nected.
Multi-collision brake
The multi-collision brake consists of automat-
ic braking activated by the Airbag control
unit. It is activated when, in the event of an
accident, the Airbag control unit detects de-
celerations above the activation level, and
braking is managed by the ESC system.
In the event of an accident, the multi-collision
brake can help the driver by braking to avoid
the risk of skidding during the accident and
causing other collisions.
The following actions control automatic brak-
ing during the accident:
When the driver presses the accelerator,
●
the automatic braking does not take place.
When the braking pressure through press-
●
ing the brake pedal is greater than the sys-
tem's braking pressure the vehicle will brake
automatically.
Multi-collision braking will not be available
●
if there is an anomaly in the ESC system.

Braking and parking
Electromechanical brake servo (eBKV)
With the ignition switched on, the electrome-
chanical brake servo supports the force of
the foot by increasing the pressure that the
driver exerts on the brake pedal. When the
brakes are applied by the driver assist sys-
tems, such as those regulated by the ACC
(adaptive cruise control) or emergency brak-
ing, the brake pedal may move downwards.
After disconnecting the ignition, the assis-
tance of the brake servo is progressively re-
duced. Once stopped, immobilise the vehicle
to prevent it from moving.
Please follow the parking instructions
›››
page 276.
If the electromechanical brake servo does
not work, the red symbol indicating failure

in the brake system appears in the instrument
panel. When braking with the faulty electro-
mechanical brake servo, vibration of the
brake pedal may occur.
If the electromechanical brake servo is not
working, the brake pedal must be pressed
harder, as the braking distance increases due
to the lack of assistance from the servo brake.
The braking force results from a combination
of the braking produced by the electric motor
(recuperation) and the mechanical or con-
ventional braking initiated by the driver using
the brake pedal 1) .
WARNING
Driving at high speed on icy, slippery wet
ground can result in loss of vehicle control
and serious injury to the driver and passen-
gers.
The ESC, ABS, TCS, EDS or electronic tor-
●
que management are not in a position to
overcome the limits imposed by physics.
Always bear this in mind, especially on wet
or slippery roads. If you notice the systems
cutting in, you should reduce your speed
immediately to suit the road and traffic
conditions. Do not be encouraged to take
risks by the presence of more safety sys-
tems. If you do, an accident may occur.
Please remember that the accident risk
●
always increases if you drive fast, espe-
cially in corners or on a slippery road, or if
you follow too close behind the vehicle in
front of you. The ESC, ABS, brake assist,
EDS and the electronic torque control sys-
tem cannot prevent accidents: risk of acci-
dents!
Accelerate with caution on slippery sur-
●
faces (for example, icy or snow-covered).
Despite the control systems, the driven
wheels could spin, affecting the stability of
the vehicle: risk of accident!
