button once or twice, PASSENGER AIRBAG
OFF indicator lamp1 located in the center
console lights up for approx. 6 seconds
and then goes out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized
Mercedes-Benz Center before seating any
child on the passenger seat.

"Practical hints" section (page 294).
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Warning!
G
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
front passenger airbag will not deploy only if
the PASSENGER AIRBAG OFF indicator lamp
remains illuminated.
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the front passenger seat until the system
has been repaired.

74 Safety and SecurityDriving safety systemsContinuos steady brake pedal pressure
yields the advantagesprovided by the ABS,
namely braking power and ability to steer
the vehicle.
The - warning lamp in the instrument
cluster lights up when you turn the key in
the starter switch to position2 or press
the KEYLESS-GO* (if so equipped)
start/stop button twice. It goes out when
the engine is running.
More information can be found in the
"Practical hints" section (
page 289).
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing the braking distance. Apply
continuous full braking pressure until the
emergency braking situation is over. The
ABS will prevent the wheels from locking.
When you release the brake pedal, the
brakes function again as normal. The BAS
is then deactivated.
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction. The
ABS cannot prevent accidents, including
those resulting from excessive speed in
turns, following another vehicle too closely,
or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ABS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.

ESP
The Electronic Stability Program (ESP)
monitors the vehicle's traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP works to
stabilize the vehicle. The ESP is especially
useful during take-off and on wet or slip-
pery road surfaces.
The ESP warning lamp v in the instru-
ment cluster flashes when the ESP is en-
gaged.
The ESP warning lamp v in the instru-
ment cluster lights up when you turn the
key in the starter switch to position2 or
press the KEYLESS-GO* (if so equipped)
start/stop button twice. It goes out when
the engine is running.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that af-
forded by the condition of the vehicle brakes
and tires or the traction. The BAS cannot
prevent accidents, including those resulting
from excessive speed in turns, following an-
other 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.
Warning!
G
Never switch off the ESP when you see the
ESP warning lamp
v
flashing in the in-
strument cluster. In this case proceed as fol-
lows:


While driving off, apply as little throttle
as possible


While driving ease up on the accelerator


Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.

To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have wheels cut into
surfaces for better grip such as:

!Because of the ESP’s automatic opera-
tion, the engine must be shut off (key in
starter switch position0 or1) when:

the parking brake is being tested on
a brake test dynamometer


the vehicle is being towed with the
front axle raised
Active braking action through the ESP
may otherwise seriously damage the
rear axle brake system.
The ESP will only function properly if
you use wheels of the recommended
tire size.
Warning!

The ESP should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.

The SBC brake system is automatically ac-
tivated when you:

unlock the vehicle with the key or the
KEYLESS-GO*


open the driver’s or passenger door


turn the key in the starter switch to
position1


in vehicles with KEYLESS-GO*, press
start/stop button on selector lever
once


depress the brake pedal


release the parking brake
Warning!
G
The SBC brake system requires electrical
power to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its
limp-home (emergency operation) mode. In
such a case, the red brake warning lamp
(page 291) and warning messages in the
instrument cluster (
page 305) light up
while driving. To brake, the driver must then
apply significantly greater brake pedal pres-
sure and depress the pedal much further to
obtain the expected braking effect. If neces-
sary, apply full pressure to the brake pedal.
Brakes are only applied to the front wheels.
Stopping distance is increased!
If there is a malfunction in the SBC brake
system, we recommend that the vehicle be
transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment. A tow bar must be used if cir-
cumstances do not permit the use of the
recommended towing methods and the ve-
hicle requires towing with all four wheels on
the ground. Towing the vehicle with all four
wheels on the ground is only permissible
for distances up to 30 miles (50 km) and at
a speed not to exceed 30 mph (50 km/h).
For more information, refer to "Towing the
vehicle" (
page 348).

The SBC brake servo assistance switches
off automatically when you:

turn the key in the starter switch to
position0 or remove the key (after ap-
proximately two minutes)


lock the vehicle with the SmartKey
from outside (after approximately
20 seconds)
Note on driving with the SBC


Following extended periods of only mi-
nor loads to your brake system, you
should occasionally apply the brakes
when traveling at high speeds. This im-
proves the grip of the brake pads.
iIf the SBC brake system is activated
when the brake pedal is first de-
pressed, you may feel a reduced pedal
resistance and longer pedal travel than
normal. When releasing the pedal, you
may also feel the brake pedal pulsate
and you may hear a sound which is
caused by the activation of the SBC
pump. This is normal and not an indica-
tion of a malfunction. Pedal travel re-
turns to normal when you release the
brake pedal and the sound soon ceas-
es.
Warning!
G
Have brake pad replacement and other work
on the SBC brake system carried out by
qualified technicians only. Contact your au-
thorized Mercedes-Benz Center for further
information. The SBC brake system must be
deactivated prior to working on the system.
High pressure is intermittently built up in the
system as part of its automatic self-test. In
addition, the system is automatically acti-
vated when the vehicle is unlocked by re-
mote control, when the driver or passenger
door is opened, when the key in the starter
switch is turned to position1, when the
brake pedal is depressed or when the park-
ing brake is released. Failure to deactivate
the system prior to maintenance will cause
brake pistons to extend and brake fluid to
leak, which may result in injuries (contu-
sions and acid burns). Extended brake pis-
tons may also cause injury.
Warning!
G
Be very careful not to endanger other road
users when you apply the brakes.
