Assist (Y page 239) in the on-board computer.
When deactivated, the distance warning func-
tion and the autonomous braking function are
also deactivated.
If Active Brake Assist is deactivated, the 00D4
symbol appears in the assistance graphic dis-
play.
If DSR (Y page 215) is activated, Active Brake
Assist is deactivated.
Distance warning function General information
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.
Important safety notesi Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 66).G
WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
The distance warning function may not give
warnings in all critical situations. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Always adapt your speed to suit the prevailing
road and traffic conditions. G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations. In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and do not rely solely on the distance
warning function.
Function Starting at a speed of approximately 4 mph
(7 km/h), the distance warning function warns
you if you rapidly approach a vehicle in front. An
intermittent warning tone will then sound, and
the 00BA 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, provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the system to display a warning.
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 exten-
ded period of time.
Up to a speed of approximately 44 mph
(70 km/ h), the distance warning function can
also react to stationary obstacles, such as stop-
ped or parked vehicles.
Autonomous braking function If the driver does not react to the distance warn-
ing signal in a critical situation, Active Brake
Assist can assist the driver with the autonomous braking function.
The autonomous braking function is available in
the following speed ranges:
R 4 - 65 mph (7 - 105 km/ h)for moving objects
R 4 - 31 mph (7 - 50 km/h) for stationary
objects
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the Autonomous Braking Func-
tion to intervene.
If the autonomous braking function requires a
particularly high braking force, preventative 68

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 vehi-
cle 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/4ETS (Electronic Traction System) 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 transfer-
red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP ®
.
In appropriate driving situations, activate the
offroad program:

Important safety notes G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further driv- ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop. !
Only operate the vehicle for a maximum of
ten seconds on a brake test dynamometer.
Switch off the ignition.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
ESP ®
is only deactivated if the 00BBwarning
lamp is lit continuously.
If the 00E5 warning lamp and the 00BBwarning
lamp are lit continuously, ESP ®
is not available
due to a malfunction.
Observe the information on warning lamps
(Y page 279) and display messages which may
be shown in the instrument cluster
(Y page 246).
i Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly.
Characteristics of ESP ® General information
If the 00E5 ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the 00E5ESP®
warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X Only depress the accelerator pedal as far as
necessary when pulling away.
X Adapt your driving style to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle stops moving. The engine starts automatically when
the driver wants to pull away again. ESP ®
remains in its previously selected status, e.g. if
ESP ®
was deactivated before the engine was
automatically switched off. 70
Driving safety systemsSafety

wind driving assistance function integrated in
ESP ®
noticeably reduces these impairments.
ESP ®
intervenes automatically according to the
direction and intensity of the crosswinds affect-
ing your vehicle.
ESP ®
intervenes with stabilizing braking to
assist you in keeping the vehicle in the lane.
Crosswind Assist is active at vehicle speeds
above 50 mph (80 km/h)when driving straight
ahead or cornering gently.
Important safety notes Crosswind Assist does not work if ESP ®
is
switched off or deactivated because of a mal-
function. EBD (electronic brake force distribu-
tion)
General information EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 66).G
WARNING
If EBD is malfunctioning, the rear wheels can
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 spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 277) as well as display
messages (Y page 248). ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 183) and hill start
assist (Y page 143). Active Brake Assist with cross-traffic
function
General information i
Pay attention to the important safety notes
in the "Driving safety systems" section
(Y page 66).
Active Brake Assist with cross-traffic function
can help you to minimize the risk of a collision
with a vehicle in front or a pedestrian and reduce
the effects of such a collision. If the Active Brake Assist with cross-traffic function detects a risk
of collision, you will be warned visually and
acoustically and, if necessary, your brake appli-
cation will be assisted according to the situa-
tion. If you do not react, the system can also
react by braking automatically. In the event of a detected risk of collision due to crossing traffic,you will also be visually and acoustically warned
as well as assisted by the brake boosting effect according to the situation.
Active Brake Assist with cross-traffic function is
only available in vehicles with the Driving Assis-
tance Plus package.
For Active Brake Assist with cross-traffic func-
tion to assist you when driving, the radar sensor
system and the camera system must be opera-
tional.
If the radar sensor system or the camera system
is malfunctioning, Active Brake Assist with
cross-traffic function is restricted or no longer
available. The brake system is still available with complete brake boosting effect and BAS.
The radar sensor system and camera system
help Active Brake Assist with cross-traffic func-
tion to detect obstacles that are in the path of
your vehicle for an extended period of time.
In addition, pedestrians in the path of your vehi- cle can be detected.
Active Brake Assist with cross-traffic function
detects pedestrians using typical characteris-
tics such as body contours and the posture of a
person standing upright.
i Observe the restrictions described in the
"Important safety notes" section
(Y page 73). 72
Driving safety systemsSafety

Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensors checked at a qualified specialist
workshop. This also applies to collisions at slow speeds where there is no visible damage to the
front of the vehicle.
Following damage to the windshield, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.
Function X
To activate or deactivate: activate or deac-
tivate Active Brake Assist with cross-traffic
function using the on-board computer
(Y page 239).
If the Active Brake Assist with cross-traffic
function is deactivated, the 00D4symbol
appears in the multifunction display.
If you have activated DSR (Y page 215), the
Active Brake Assist with cross-traffic function is
deactivated.
Starting at a speed of around 4 mph (7 km/h),
this function warns you if you rapidly approach a
vehicle in front. An intermittent warning tone
will then sound and the 00BAdistance warning
lamp will light up in the instrument cluster.
X Brake immediately to defuse the situation.
or X Take evasive action provided it is safe to do
so.
Active Brake Assist with cross-traffic function
can also brake the vehicle automatically under
the following conditions:
R the driver and front-passenger have their seat
belts fastened
and
R the vehicle speed is between approximately
4 mph (7 km/h) and 124 mph (200 km/h)
Up to a speed of approximately 44 mph
(70 km/h), Active Brake Assist with cross-traffic function may react to:
R stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
i If there is an increased risk of a collision,
preventive passenger protection measures
(PRE-SAFE ®
) are triggered (Y page 58).
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive action or accelerate significantly, the vehicle
may perform automatic emergency braking, up
to the point of full brake application. Automatic
emergency braking is not performed until imme-
diately prior to an imminent accident.
If you apply the brake yourself in a critical sit-
uation or during autonomous braking, braking
assistance is provided according to the situa-
tion. If necessary, this increases the brake pres- sure up to full brake application.
To avoid a collision, Active Brake Assist with
cross-traffic function calculates the brake force
necessary if:
R you approach an obstacle, and
R Active Brake Assist with cross-traffic function
has detected a risk of a collision
When driving at a speed under 20 mph
(30 km/h) : if you depress the brake pedal,
Active Brake Assist with cross-traffic function is
activated. The increase in brake pressure from
Active Brake Assist with cross-traffic function is
carried out at the last possible moment.
When driving at a speed above 20 mph
(30 km/h): if you depress the brake pedal
sharply, Active Brake Assist with cross-traffic
function automatically increases the brake pres- sure to a degree suited to the traffic situation.
Active Brake Assist with cross-traffic function
provides braking assistance in hazardous situa-
tions with vehicles in front within a speed range
between 4 mph (7 km/h) and 155 mph
(250 km/h).
Up to a speed of approximately 44 mph
(70 km/h) the Active Brake Assist with cross-
traffic function assists you with braking in haz-
ardous situations with:
R stationary obstacles in the path of the vehicle,
e.g. stopped or parked vehicles
R stationary pedestrians in the path of the vehi-
cle
R obstacles crossing your path that move in the
detection range of the sensors and are detec- ted
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
You can prevent the intervention of Active Brake Assist with cross-traffic function at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal 74
