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, complex but
non-critical driving conditions may also cause
Brake Assist to engage.
If Adaptive Brake Assist is not available due to a
malfunctioning radar sensor system, the brake
system remains available with full brake boost-
ing effect and BAS.
Adaptive brake lights
The adaptive brake lights warn following traffic
in an emergency braking situation:
R
by flashing brake lamps
R
by activating the hazard warning lamps
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 67).
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/4ETS (Electronic Traction System)
i
Observe the "Important safety notes" sec-
tion (
Y
page 67).
ETS traction control is part of ESP
®
. On vehicles
with 4MATIC, 4ETS 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, e.g. if
the road surface is slippery on one side. In addi-
tion, more drive torque is transferred to the
wheel or wheels with traction.
Traction control remains active if you deactivate
ESP
®
.
Important safety notes
i
Read the "Important safety notes" section
(
Y
page 67).
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 towing your vehicle with the rear axle
raised, observe the notes on ESP ®
(
Y
page 337).
If the å ESP
®
OFF warning lamp lights up
continuously, ESP
®
is deactivated.
If the ÷ ESP ® warning lamp lights up contin-
uously, ESP
®
is not available due to a malfunc-
tion.
Read the information on warning lamps
(
Y
page 275) and display messages that may be
shown in the instrument cluster (
Y
page 242).
