Drive on carefully. Have ABS checked

immediately at a qualified specialist

workshop.

When ABS is malfunctioning, other systems,

including driving safety systems, will also

become inoperative. Observe the information

on the ABS warning lamp (

Y

page 236) and

display messages which may be shown in the

instrument cluster (

Y

page 209).

ABS regulates brake pressure in such a way

that the wheels do not lock when you brake.

This allows you to continue steering the

vehicle when braking.
ABS works from a speed of about 5 mph

(8 km/h) upwards, regardless of road-surface

conditions. ABS works on slippery surfaces,

even if you only brake gently.
The yellow ! ABS warning lamp in the

instrument cluster lights up when the ignition

is switched on. It goes out when the engine is

running.

Braking

X

If ABS intervenes: continue to depress the

brake pedal vigorously until the braking

situation is over.

X

To make a full brake application:

depress the brake pedal with full force.

If ABS intervenes when braking, you will feel

a pulsing in the brake pedal.
The pulsating brake pedal can be an

indication of hazardous road conditions, and

functions as a reminder to take extra care

while driving.

BAS (Brake Assist System)

i

Observe the "Important safety notes"

section (

Y

page 62).

G

WARNING

If BAS is malfunctioning, the braking distance

in an emergency braking situation is

increased. There is a risk of an accident.

In an emergency braking situation, depress

the brake pedal with full force. ABS prevents

the wheels from locking.

BAS operates in emergency braking

situations. If you depress the brake pedal

quickly, BAS automatically boosts the braking

force, thus shortening the stopping distance.

X

Keep the brake pedal depressed firmly until

the emergency braking situation is over.

ABS prevents the wheels from locking.

The brakes will function as usual once you

release the brake pedal. BAS is deactivated.

BAS PLUS (Brake Assist System

PLUS)

i

Observe the "Important safety notes"

section (

Y

page 62).

BAS PLUS is only available in vehicles

equipped with DISTRONIC PLUS.
For BAS PLUS to assist you when driving, the

radar sensor system must be:

R

activated (

Y

page 203)

R

operational

With the help of the radar sensor system, BAS

PLUS can detect obstacles that are in the

path of your vehicle for an extended period of

time.
If the radar sensor system is malfunctioning,

BAS PLUS will not be available. The brake

system is still available with complete brake

boosting effect and BAS.
BAS PLUS provides braking assistance in

hazardous situations at speeds greater than

4 mph (7 km/h).
At speeds of up to approximately 40 mph

(70 km/h), BAS PLUS can also detect

stationary objects. Examples of stationary

objects are stopped or parked vehicles.
To prevent a front-end collision, BAS PLUS

calculates the brake force necessary if:

R

you approach an obstacle, and

R

BAS PLUS has detected a risk of collision
