Offroad ESP
®
(vehicles with Off-Road
Engineering package) An ESP
®
system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated on:
R Vehicles without the Offroad Engineering
package (Y page 215)
R Vehicles with the Off-Road Engineering pack-
age (Y page 216)
Offroad ESP ®
intervenes with a delay if there is
oversteering or understeering, thus improving
traction.
Crosswind Assist General information
Strong crosswind gusts can impair the ability of your vehicle to drive straight ahead. The cross-
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 247). 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 182) and hill start
assist (Y page 139). 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. 72
Driving safety systemsSafety

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).
Important safety notes G
WARNING
Active Brake Assist with cross-traffic function will initially brake your vehicle by a partial
application of the brakes if a danger of colli-
sion is detected. There may be a collision
unless you brake yourself. Even after subse-
quent full application of the brakes a collision
cannot always be avoided, particularly when
approaching at too high a speed. There is a
risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
In the event of a partial application of the brakes,
the vehicle is braked with up to 50% of the full
braking pressure. G
WARNING
Active Brake Assist with cross-traffic function cannot always clearly identify objects and
complex traffic situations.
In such cases, Active Brake Assist with cross-
traffic function might:
R issue an unnecessary warning or engage
R neither give a warning nor intervene
There is a risk of an accident. Always pay particular attention to the traffic
situation and be prepared to brake, especially
if Active Brake Assist with cross-traffic func-
tion alerts you. Terminate the intervention in a
non-critical driving situation. G
WARNING
Active Brake Assist with cross-traffic function cannot always clearly identify people, partic-
ularly if they are moving. Active Brake Assist
with cross-traffic function cannot intervene in
these cases. There is a risk of an accident.
Always pay particular attention to the traffic
situation and be prepared to brake, especially if Active Brake Assist with cross-traffic func-
tion alerts you.
In order to maintain the appropriate distance to the vehicle in front and thus prevent a collision, you must apply the brakes yourself. G
WARNING
Active Brake Assist with cross-traffic function does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R when cornering
As a result, Active Brake Assist with cross-
traffic function may not warn you or engage in
all critical situations. There is a risk of an acci-
dent.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, the rec-
ognition can be impaired.
Recognition by the radar sensor system is also
impaired if:
R there is dirt on the sensors or anything else
covering the sensors
R there is interference by other radar sources
R there are strong radar reflections, for exam-
ple in parking garages
R a narrow vehicle is traveling in front, e.g. a
motorbike Driving safety systems
73Safety Z

R
a vehicle is traveling in front on a different line
relative to the center of your vehicle
R vehicles quickly move into the radar sensor
system detection range
Recognition by the camera system is also
impaired in the event of:
R dirt on the camera or if the camera is covered
R glare on the camera system, e.g. from the sun
being low in the sky
R darkness
R or if:
-
pedestrians move quickly, e.g. into the path
of the vehicle
- the camera system no longer recognizes a
pedestrian as a person due to special cloth-
ing or other objects
- a pedestrian is concealed by other objects
- the typical outline of a person is not distin-
guishable from the background
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 thefront 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 238).
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 214), 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). 74
