R

strong radar reflections, for example, in

multi-storey car parks

R

a narrow vehicle travelling in front, e.g. a

motorcycle

R

a vehicle travelling in front on a different

line

Following damage to the front end of the vehi-

cle, have the configuration and operation of

the radar sensor checked at a qualified spe-

cialist workshop. This also applies to colli-

sions at slow speeds where there is no visible

damage to the front of the vehicle.

Adaptive brake lamps

Adaptive Brake Assist warns following traffic

in an emergency braking situation:

R

by means of flashing brake lamps

R

the hazard warning lamps are activated

If you brake sharply from a speed of more

than 50 km/h or if braking is assisted by BAS

or BAS PLUS, the brake lamps flash rapidly.

In this way, traffic travelling behind you is

warned in an even more noticeable manner.

If you brake sharply from a speed of more

than 70 km/h to a standstill, the hazard warn-

ing lamps are activated automatically. If the

brakes are applied again, the brake lamps

light up continuously. The hazard warning

lamps switch off automatically if you travel

faster than 10 km/h. You can also switch off

the hazard warning lamps using the hazard

warning button (Y page 110).

ESP

®

(Electronic Stability Program)

General notes

i

Observe the "Important safety notes" sec-

tion (Y page 64).

ESP

®

monitors driving stability and traction,

i.e. power transmission between the tyres

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 stabilise 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 stabilise the vehicle during braking.

ETS (Electronic Traction System)

i

Observe the "Important safety notes" sec-

tion (Y page 64).

ETS traction control is part of ESP

®

.

ETS 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.

ETS remains active when you deactivate

ESP

®

.

Important safety notes

G

WARNING

If ESP

®

is malfunctioning, ESP

®

is unable to

stabilise the vehicle. In addition, other driving

safety systems are switched off. This increa-

ses the risk of skidding and an accident.

Drive on carefully. Have ESP

®

checked at a

qualified specialist workshop.

!

When testing the electric parking brake

on a braking dynamometer, switch off the

ignition. Application of the brakes by

ESP

®

may otherwise destroy the brake sys-

tem.

When towing your vehicle with the front axle

raised, observe the notes on

ESP

®

(Y page 310).

ESP

®

is deactivated if the å ESP

®

OFF

warning lamp in the instrument cluster lights

up continuously when the engine is running.

If the ÷ ESP

®

warning lamp and the

å ESP

®

OFF warning lamp are lit contin-

uously, ESP

®

is not available due to a mal-

function.
