Adaptive brake lamps
The adaptive brake lights warn following
traffic in an emergency situation:
If you brake the vehicle sharply from a
speed of more than 50 km/h the brake lamps
flash rapidly.
If the vehicle is sharply braked to a stand-
still at a speed of over 70 km/h, the hazard
warning lamps are also switched on auto-
matically. The hazard warning lamps
switch off automatically if you subse-
quently drive faster than 10 km/h.
Driving with ESP
®
G
WARNING
If ESP
®
is malfunctioning, ESP
®
is unable
to stabilise the vehicle. In addition, other
driving safety systems are switched off.
This increases the risk of skidding and an
accident.
Drive on carefully. Have ESP
®
checked at
a qualified specialist workshop.
Within physical limits, ESP
®
can monitor
and improve the driving stability and trac-
tion in the following situations:
R
when pulling away on wet or slippery
road surfaces
R
when braking
R
in case of strong crosswinds
If the vehicle deviates from the direction
desired by the driver, ESP
®
can stabilise the
vehicle by intervening in the following
ways:
R
braking one or more wheels accordingly
R
adjusting the engine output according to
the situation
ESP
®
comprises ETS (Electronic Traction
System) and Crosswind Assist.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away or
accelerate on slippery surfaces, for example
if the road surface is slippery on one side.
If the ÷ warning lamp goes out before
beginning the journey, ESP
®
is active.
If the ÷ warning lamp flashes in the
instrument cluster, ESP
®
is intervening.
If ESP
®
intervenes, observe the following
points:
R
pull away carefully: only depress the
accelerator pedal as far as necessary
R
adapt your driving style to the prevailing
road and weather conditions
If the ÷ ESP
®
warning lamp lights up
continuously, ESP
®
is not available due to a
malfunction. Crosswind Assist is then also
no longer active.
Observe the additional information on indi-
cator and warning lamps and display mes-
sages.
Crosswind Assist recognises suddenly
occurring crosswinds and helps the driver
to keep the vehicle in the correct lane. The
vehicle is stabilised using a targeted and
one-sided application of the brakes.
Crosswind Assist is active at vehicle speeds
above 70 km/h when driving straight ahead
or cornering gently.
Information on EBD (Electronic Brake-
force Distribution)
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
G
WARNING
If EBD is malfunctioning, the rear wheels
can lock, e.g. under full braking. This
