WARNING
Adaptive Brake Assist does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause Brake Assist to intervene.
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.
Adaptive brake lights
The adaptive brake lights warn following traffic
in an emergency braking situation:
R
by 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 warning
lamps are activated automatically. If the brakes
are applied again, the brake lamps light up con-
tinuously. 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
(

ESP
®
(Electronic Stability Program)
General notes
i
Observe the "Important safety notes" sec-
tion (
Y
page 61).
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 vehi-
cle 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 61).
ETS traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually 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 transfer-
red to the wheel or wheels with traction.
Traction control remains active if you deactivate
ESP
®
.

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 towing your vehicle with the front axle
raised, observe the notes on ESP
®
(
Y
page 262).
When towing your vehicle away with the rear
axle raised, observe the notes on ESP
®
(
Y
page 262).
If the å ESP
®
OFF warning lamp lights up
continuously, ESP ® is deactivated.
If the ÷ ESP
®
warning lamp and the å
warning lamp are lit continuously, ESP ® is not
available due to a malfunction.
