ESP®trailer stabilization
General information
If your vehicle/trailer combination begins to
swerve, ESP
®assists you in this situation.
ESP®slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilized.
Important safety notes
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP
®can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
ESP
®trailer stabilization is active above
speeds of about 65 km/h.
ESP
®trailer stabilization does not work if
ESP®is deactivated or disabled because of a
malfunction.
Crosswind Assist
General information
Strong crosswinds can cause your vehicle to
deviate from a straight course. The crosswind driving assistance function integrated in
ESP
®noticeably reduces these impairments.
ESP
®intervenes automatically according to
the direction and intensity of the crosswinds
affecting 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
deactivated or disabled because of a mal-
function.
EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
GWARNING
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 (
Ypage 294) as well as dis-
play messages (
Ypage 261).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi- tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (
Ypage 194) and
hill start assist (
Ypage 157).
PRE-SAFE®Brake
General information
PRE-SAFE®Brake can help you to minimize
the risk of a collision with a vehicle ahead or a
pedestrian, and reduce the effects of such a
Driving safety systems75

Z

You can prevent the intervention of the PRE-
SAFE®Brake at any time by:
Rdepressing the accelerator pedal further.
Ractivating kickdown.
Rreleasing the brake pedal.
The braking action of PRE-SAFE
®Brake is
ended automatically if:
Ryou maneuver to avoid the obstacle.
Rthere is no longer a risk of collision.
Rthere is no longer an obstacle detected in
front of your vehicle.
STEER CONTROL
General information
STEER CONTROL helps you by transmitting a noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization.
This steering assistance is provided in partic-
ular if:
Rboth right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
Rthe vehicle starts to skid.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
No steering support is provided from STEER
CONTROL, if:
RESP®is malfunctioning.
Rthe lighting is faulty.
If ESP
®is malfunctioning, you will be assisted
further by the electrical power steering.
