If the 75 indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the light
goes out, or check whether objects are
caught under or around the seat.
More information about air bag display mes-
sages (
page 393).
In the event of a collision, the air bag control
unit will not allow front passenger front
air bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child re-
straint, the 75 indicator lamp will
illuminate when the engine is started and re-
main illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
75 indicator lamp will illuminate
when the engine is started and remain illu-
minated, indicating that the front passenger
front air bag is deactivated.
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 75 indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then, depending on oc-
cupant weight sensor readings from the
seat, remain illuminated or go out. With the
75 indicator lamp illuminated, the
front passenger front air bag is deactivated.
With the 75 indicator lamp out,
the front passenger front air bag is activat-
ed.
When the OCS senses that the front passen-
g e r s e a t o c c u p a n t i s c l a s s i f i e d a s a n a d u l t o r
someone larger than a small individual, the
75 indicator lamp will illuminate
for approximately 6 seconds when the en-
gine is started and then go out, indicating
that the front passenger front air bag is acti-
vated.
92 Safety and SecurityDriving safety systemsIn this section you will find information on
the following driving safety systems:
ABS (A

BAS (B

ssist S
ystem)
ESP
® (E
lectronic S
tability P
rogram)
Electrohydraulic brake system
4MATIC (Four Wheel Electronic
Traction System)
ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
The - indicator lamp in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is run-
ning.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP
®, electrohydraulic brake system
and 4MATIC is only achieved with win-
ter tires (
page 358), or snow chains
as required.
Warning!
G
The following factors increase the risk of ac-
cidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, ESP
®, electrohydraulic brake
system and 4MATIC cannot reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.

iIf you drive in countries where vehicles
drive on the other side of the road than
the country where the vehicle is regis-
tered, you must have the headlamps
modified for symmetrical low beams.
Relevant information can be obtained
at your authorized Mercedes-Benz
Center.iVehicles equipped with active Bi-Xe-
non* headlamps:
The active Bi-Xenon headlamps moni-
tor your steering angle and driving
speed, then automatically shift their
beams to either side to better follow
the curvature of the road ahead, in-
creasing usable illumination over con-
ventional headlamps.
iWith the SmartKey removed from the
starter switch or the engine turned off
with KEYLESS-GO* and the driver’s
door open, a warning sounds if the
parking lamps or low beam headlamps
are switched on.
The message
Switch off lamps
appears in the multifunction display.

Warning!
G
If the exterior lamp switch is set toU,
the headlamps may switch off unexpect-
edly when the system senses bright am-
bient light, for example light from
oncoming traffic.
the headlamps will not be automatically
switched on under foggy conditions.
To minimize risk to you and to others, acti-
vate headlamps by turning exterior lamp
switch to B when driving or when traffic
and/or ambient lighting conditions require
you to do so.
In low ambient lighting conditions, only
switch from position U to B with the
vehicle at a standstill in a safe location.
Switching from U to B will briefly
switch off the headlamps. Doing so while
driving in low ambient lighting conditions
may result in an accident.
The automatic headlamp feature is only an
aid to the driver. The driver is responsible for
the operation of the vehicle’s lights at all
times.
