In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
Always pay careful attention to the traffic
situation and do not rely solely on the
distance warning function.
Function
X To activate/deactivate: activate or
deactivate the distance warning function in
the on-board computer (Y page 276).
When the distance warning function is
activated, the multifunction display shows
the 0003 symbol, as long as the HOLD
function is not switched on (Y page 211). On
vehicles with Active Parking Assist, the
0003 symbol is displayed when Pis engaged
or you are driving faster than 22 mph
(35 km/h).
The distance warning function 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 the distance warning
function detects that there is a risk of a
collision, you will be warned visually and
acoustically. The distance warning function
cannot prevent a collision withou tyour
intervention.
Starting at a speed of around 20 mph
(30 km/h), this function warns you if you
rapidly approach a vehicle in front.An
intermitten twarning tone will then sound and
the 000F distance warning lamp will light up
in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action, provide ditis safe to
do so.
For the distance warning function to assist
you when driving, the function must be
activated in the on-board computer and be
operational (Y page 276). Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display unnecessary warnings.
With the help of the radar sensor system, the
distance warning function can detect
obstacles that are in the path of your vehicle
for an extended period of time.
At speeds up to 40 mph (70 km/h), the
distance warning function may also detect
stationary obstacles, for example stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
In particular, the detection of obstacles can
be impaired if:
R there is dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
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
collisions at low speeds where there is no
visible damage to the front of the vehicle.
Adaptive Brake Assist i
Observe the "Important safety notes"
section (Y page 66). G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic
situations. In these cases, Adaptive Brake
Assist may not intervene. There is a risk of an
accident. Driving safety systems
69Safety
Z

Always pay careful attention to the traffic
situatio
nand be ready to brake. G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R to stationary obstacles
R when cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic
situatio nand be ready to brake.
Adaptive Brake Assist provides braking
assistance in hazardous situations at speeds
greater than 20 mph (30 km/h) and uses
rada rsensor technology to assess the traffic
situation.
With the help of Adaptive Brake Assist, the
distance warning signal can detec tobstacles
that are in the path of your vehicle for an
extended period of time.
Should you approach an obstacle and
Adaptive Brake Assist has detected a risk of
collision, Adaptive Brake Assist calculates the
braking force necessary to avoid a rear-end
collision. Should you apply the brakes
vigorously, 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 rear-end
collision.
R no obstacle is detected in fron tofyour
vehicle.
Adaptive Brake Assist is then deactivated. If Adaptive Brake Assist requires particularly
high brake pressure, preventive passenger
protection measures (PRE-SAFE
®
) are
deployed simultaneously.
Up to vehicle speeds of around 155 mph
(250 km/h), adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
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
collisions at low speeds where there is no
visible damage to the front of the vehicle. ESP

(Electronic Stability Program)
General notes i
Observe the "Important safety notes"
section (Y page 66).
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 70
Driving safety systemsSafety

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.
4ETS (Electronic Traction System) 4ETS traction control is part of ESP
®
.
Traction control brakes the drive wheels
individually 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
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP ®
.
In appropriate driving situations, activate the
off-road program:

trailer stabilization G
WARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from
swerving .Trailers with a high center of gravity
can tip over before ESP ®
can detect this.
There is a risk of an accident.
Always adapt yourd riving style to the
prevailing road and weather conditions. 72
Driving safety systemsSafety

If yourv
ehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detec tifthe vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has
stabilized.
Trailer stabilization is active above speeds of
about 37 mph (60 km/h).
Trailer stabilization does not work if ESP ®
is
deactivated because of a malfunction.
Crosswindd riving assistance Strong crosswinds ca
ncause your vehicle to
deviate from a straigh tcourse. The crosswind
driving assistance function integrated into
ESP ®
significantly reduces these effects.
ESP ®
intervenes automatically according to
the direction and intensity of the crosswinds
affecting your vehicle.
When driving on straight roads or gentle
bends, your vehicle is kept safely on course
by a stabilizing brake intervention.
Crosswind driving assistance is active above
a vehicle speed of 80 km/h.
Crosswind driving assistance does not work
if ESP ®
is deactivated or disabled because of
a malfunction. EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section (Y page 66). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Y page 323) as well as
display messages (Y page 289).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. ADAPTIVE BRAKE

If PRE-SAFE ®
Brake is to aid you, the radar
sensor system must be:
R activated (Y page 281)
R operational
With the help of the radar sensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE ®
Brake can help you to minimize
the risk of a collision with a vehicle ahead or
reduce the effects of such a collision. If PRE-
SAFE ®
Brake has detected a risk of collision,
you will be warned visually and acoustically
as well as by automatic braking. PRE-SAFE ®
Brake cannot prevent a collision without your
intervention.
Starting at a speed of around
4 mph (7 km/h), this function warns you if
you very quickly approach a vehicle in front. Driving safety systems

X Take evasive action provided it is safe to do
so.
From a speed of approximately
4 mph (7 km/h), if the driver and front
passenge rhave fastened their seat belts,
PRE-SAFE ®
Brake can brake the vehicle
automatically at speeds up to approximately
124 mph (200 km/h).
Due to the nature of the system, particularly

R depressing the accelerator peda lfurther
R activating kickdown
R releasing the brake pedal
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you maneuve rto avoid the obstacle.
R there is no longer any danger of a rear-end
collision.
R there is no longer an obstacle detected in
front of your vehicle.
If you have activated DSR (Y page 250), PRE-
SAFE ®
Brake is deactivated.
At speeds of up to approximately 40 mph
(70 km/h) ,PRE-SAFE ®
Brake can also detect
stationary objects .Examples of stationary
objects are stopped or parked vehicles.
If you approach an obstacle and PRE-SAFE ®
Brake detects a ris kofacollision, the system
will alert you both visuall yand acoustically. If
you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently .Ifthere is an increased risk
of collision, preventative passenger
protection measures (PRE-SAFE ®
) are activated (Y
page 54). If, at speeds over
20 mph (30 km/h), a risk of collision remains
and you do not brake, take evasive action or
significantly accelerate, automatic braking
may be performed up to alevel of automatic
emergency braking. Automatic emergency
braking is not performed until immediately
prior to an accident that can no longer be
avoided. G
WARNING
PRE-SAFE ®
Brake will initially brake your
vehicle by a partial application of the brakes
if a danger of collision is detected. There may
be a collision unless you also brake.
Automatic emergency brakin gcannot prevent
a collision .There is a risk of an accident.
Always apply the brakes yourself and try to
