The BAS is designed to maximize the vehicle’s braking
capability during emergency braking maneuvers by
having maximum power boost applied to the brakes
more quickly in emergency braking conditions than
might otherwise be afforded solely by the driver’s
braking style. This can help reduce braking distances
over what ordinary driving and braking style might do.
The BAS complements the antilock brake system (ABS).Applying the brakes very quickly results in maximum
BAS assistance.
To receive the benefit of the system you must apply
continuous full braking power during the stopping
sequence. Do not reduce brake pedal pressure.
Once the brake pedal is released, the BAS is deactivated.
If the BAS warning message is displayed, a malfunction
has been detected in the system. The brake system
functions in the usual manner, but without BAS.
With the ABS malfunctioning, the BAS is also switched
off.
If a BAS warning message is displayed, have the BAS
checked at your authorized Mercedes-Benz Center as
soon as possible.
Wa r n i n g !
BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded. The BAS cannot prevent
ac c id ent s, i nc l udi ng t hose resul tin g from exc es si ve
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a BAS equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.

Antilock brake system (ABS)
Important!
The ABS improves steering control of the vehicle during
hard braking maneuvers.
The ABS prevents the wheels from locking up above a
vehicle speed of approximately 5 mph (8 km / h)
independent of road surface conditions.At the instant one of the wheels is about to lock up, a
slight pulsation can be felt in the brake pedal,
indicating that the ABS is in the regulating mode. Keep
firm and steady pressure on the brake pedal while
experiencing the pulsation.
Continuous steady brake pedal pressure results in
applying the advantages of the ABS, namely braking
power and ability to steer the vehicle.
In the case of an emergency brake maneuver keep
continuous full pressure on the brake pedal. In this
manner only can the ABS be most effective.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the
increased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and functions as a reminder to take extra
care while driving.
Wa r n i n g !
Do not pump the brake pedal, rather use firm,
steady brake pedal pressure. Pumping the brake
pedal defeats the purpose for ABS and significantly
reduces braking effectiveness.

Important!
Batteries contain materials that can harm the
environment if disposed of improperly. Recycling of
batteries is the preferred method of disposal. For
disposal, please follow manufacturer’s recommendation
on battery package.
Replacement Battery:
Lithium, type CR 2025 or equivalent.
Synchronizing remote control
The remote control may have to be resynchronized, if
the vehicle cannot be locked or unlocked.
To synchronize insert electronic key in starter switch.
The remote control should once again be operational.Emergency engine shut-down
If the engine can no longer be stopped using the
electronic key, the engine can be turned of f by removing
two fuses.
For easy removal of fuses use the fuse extractor (located
in the auxiliary fuse box in the trunk) to pull out the
fuses marked on the fuse chart as “ENGINE
EMERGENCY OFF”.
The fuse chart is located in the fuse box in the
passenger compartment.
For fuses see page 295.

To slide roof closed or to raise the roof at the rear:
turn crank clockwise.
To slide the roof open or to lower the roof at the rear:
turn crank counterclockwise.
See page 188 for instructions on synchronizing the
