Bas; Adaptive Brake Lamps; Esp - Mercedes-Benz A-Class Series Owner's Manual

You should always adapt your driving style to
suit the prevailing road and weather condi-
tions.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
BAS (Brake Assist)
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
Keep the brake pedal firmly depressed until
X
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
G Risk of accident
If BAS has malfunctioned, the braking system
remains available with full brake boosting
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 50 km/h or 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

ESP

(Electronic Stability Program)
®
ESP monitors the driving stability and the
traction. Traction is the 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. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP

cle during braking.

If ESP intervenes, the d warning lamp
flashes in the instrument cluster.
G Risk of accident
If the d warning lamp in the instrument
cluster flashes, proceed as follows:
only depress the accelerator pedal as far as
