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 front of your

vehicle

Adaptive Brake Assist is then deactivated.

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 67).

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/4ETS (Electronic Traction System)

ETS/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

®

.

section (Y page 67).

WARNING

If ESP

®

is malfunctioning, ESP

®

is unable to

stabilize the vehicle. Additionally, further

driving safety systems are deactivated. This

increases the risk of skidding and an accident.

Drive on carefully. Have ESP

®

checked at a

qualified specialist workshop.

!

Vehicles with 4MATIC: switch off the

ignition when the parking brake is being

tested on a brake dynamometer.
