braking function. COLLISION PREVENTION
ASSIST PLUS can help you to minimize the
risk of a front-end collision with a vehicle
ahead or reduce the effects of such a
collision. If COLLISION PREVENTION ASSIST
PLUS detects that there is a risk of a collision,
you will be warned visually and acoustically.
In critical situations COLLISION PREVENTION
ASSIST PLUS also initiates automatic
braking.
Function
To activate/deactivate: activate or
X
deactivate COLLISION PREVENTION
ASSIST PLUS in the on-board computer
( page 201).
Y
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the æ symbol appears in the
assistance graphics display.
If the driver's seat belt is fastened,
COLLISION PREVENTION ASSIST PLUS can
brake automatically within a speed range of
between 4 mph (7 km/h) and 124 mph
(200 km/h).
COLLISION PREVENTION ASSIST PLUS can
also react to stationary obstacles with
automatic braking within a speed range of
between 4 mph (7 km/h) and 19 mph
(30 km/h).
In particular, the detection of obstacles can
be impaired if:
dirt on the sensors or anything else
R
covering the sensors
snow or heavy rain
R
interference by other radar sources
R
there are strong radar reflections, for
R
example in parking garages
a narrow vehicle traveling in front, e.g. a
R
motorbike
a vehicle traveling in front on a different line
R
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
Driving safety systems
collisions at low speeds where there is no
visible damage to the front of the vehicle.
Adaptive brake lights
Adaptive Brake Assist warns following traffic
in an emergency braking situation:
by means of flashing brake lamps
R
by activating the hazard warning lamps
R
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard
warning 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 ( page 107).

General notes

i
Observe the "Important safety notes"
section ( page 63).
Y
®
ESP monitors driving stability and traction,
i.e. power transmission between the tires 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 stabilize 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 stabilize the vehicle during braking.
ETS (Electronic Traction System)
i
Observe the "Important safety notes"
section ( page 63).
Y
ETS traction control is part of ESP
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
