strong radar reflection such as in parking
garages
BAS PLUS uses radar signals that are not
reflected well by narrow objects and
absorptive materials. For this reason BAS
PLUS will not react to persons, animals, and
approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles
driving in front of you, such as motorcycles
and vehicles driving offset from your vehicle
center.
Following a collision or accident-related
damage to the front end of the vehicle, have
the configuration and operation of the radar
sensors checked at an authorized Mercedes-
Benz Center.
If BAS PLUS 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
i Adaptive brake lamps are only available in
the USA and only on the S 600 and S65
AMG.
If you brake sharply from a speed of more
than 30 mph (50 km/h) or if braking is
assisted by BAS or BAS PLUS, the brake
lamps flash rapidly. In this way, traffic
traveling behind you is warned in an even
more noticeable manner.
If you brake from a speed of more than
40 mph (70 km/h) to a standstill, the hazard
warning lamps are switched on automatically
when the vehicle is stationary. If the brakes
are applied again, the brake lamps light up
continuously. The hazard warning lamps
switch off automatically if you drive faster
than 6 mph (10 km/h) again. You can also
switch off the hazard warning lamps using the
hazard warning lamp button (

If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize 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
slippery roads. ESP
®
can also stabilize the
vehicle during braking.
If ESP
®
intervenes, the
÷
warning lamp
flashes in the instrument cluster.

deactivate ESP
®
when the
÷
ESP

warning lamp in the instrument cluster
flashes. Proceed as follows:
R
when driving off, apply as little throttle as
possible.
R
while driving, ease up on the accelerator
pedal.
R
adapt your speed to suit the prevailing road
and weather conditions.
failure to observe these guidelines could
cause the vehicle to skid. ESP
®
cannot
prevent accidents resulting from excessive
speed.

ignition off when:
R
the electric parking brake is being tested
using a brake dynamometer.
