If adaptive Brake Assist detects a risk of col-
lision with the vehicle in front, adaptive Brake
Assist calculates the necessary brake pres-
sure to avoid this collision. If you apply the
brakes forcefully, adaptive Brake Assist will
automatically increase the braking force to a
level suitable for the traffic conditions.
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
R
you release the brake pedal
R
there is no longer any danger of a collision
R
no obstacle is detected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
If adaptive Brake Assist demands particularly
high braking force, preventative passenger
protection measures (PRE-SAFE
®
) are activa-
ted simultaneously.
Up to a speed of around 250 km/h, adaptive
Brake Assist is capable of reacting to moving
objects that have already been detected as
such at least once over the period of obser-
vation.
Up to a speed of around 70 km/h, adaptive
Brake Assist reacts to stationary obstacles.
Adaptive brake lamps
Adaptive Brake Assist warns following traffic
in an emergency braking situation:
R
by means of flashing brake lamps
R
the hazard warning lamps are activated
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly. In
this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning button (

ESP
®
(Electronic Stability Program)
General notes
i Observe the "Important safety notes" sec-
tion (
Y
page 69).
ESP
®
monitors driving stability and traction,
i.e. power transmission between the tyres
and the road surface.
If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP
®
assists the driver when
pulling away on wet or slippery roads. ESP ®
can also stabilise the vehicle during braking.
ETS/4ETS (Electronic Traction System)
i Observe the "Important safety notes" sec-
tion (
Y
page 69).
ETS/4ETS traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deacti-
vate ESP
®
.
Important safety notes
G
WARNING
If ESP
®
is malfunctioning, ESP
®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
