effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 25 km/ho r if braking is assisted by BAS,
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 switch button (Y page 81).ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between 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. If necessary, 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 slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
When ESP ®
intervenes, the dwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the d warning lamp in the instrument
cluster flashes, proceed as follows: R
do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise, the vehicle could skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Only operate the vehicle briefly (for a max-
imum of ten seconds) on a brake dyna-
mometer. Turn the key in the ignition lock
to position 0or 1. You could otherwise
damage the drive train or the brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ESP ®
trailer stabilisation If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP
®
assists you and can
detect when the trailer begins to lurch.
ESP ®
slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilised.
Trailer stabilisation is active above speeds of
about 65 km/h. G
Risk of accident
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent Driving safety systems
