RDo not pass seat belts over sharp edges.
They could tear.
RDo not make any modification that could
change the effectiveness of the seat belts.
RDo not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
RNo modifications of any kind may be made
to any components or wiring of the SRS.
RDo no change or remove any component or
part of the SRS.
RDo not install additional trim material, seat
covers, badges, etc. over the steering
wheel hub, passenger front air bag cover,
outboard sides of the seat backrests, door
trim panels, or door frame trims.
RDo not install additional electrical/
electronic equipment on or near SRS
components and wiring.
RKeep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.).
RAir bag system components will be hot after
an air bag has inflated. Do not touch them.
RNever place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
RImproper repair work on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefore only be
performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
RFor your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
RGiven the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, we strongly
recommend that you inform the subsequent
owner that the vehicle is equipped with SRS.
Also refer them to the applicable section in
the Operator’s Manual.
Front air bags
GObserve Safety notes, see page 45.
Driver’s front air bag : and passenger front
air bag ; are designed to provide increased
protection for the driver and passenger
against the risk of injuries to the head and
thorax.

to that provided by the seat belt
Rdepending on whether the respective seat

Rindependently of the other air bags in the
vehicle
The front air bags in this vehicle have been
designed to inflate in two stages. This allows
the air bags to have different rates of inflation.
The rate of inflation is based on the vehicle
deceleration rate as assessed by the air bag
control unit.
The passenger front air bag deployment is
additionally influenced by the passenger’s

The message ESC-OFF appears in the
multifunction display.
GWarning!
When the ESC OFF warning lamp å is on,
the ESC is switched off.
When the ESC warning lamp ÷ and the
ESC OFF warning lamp å are on
continuously, the ESC is not operational due
to a malfunction.
When the ESC is switched off or not
operational, vehicle stability in standard
driving maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESC.
! Avoid spinning of a drive wheel for an
extended period with the ESC switched off.
This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
XSwitching on: With the engine running,
press ESC switch : briefly.
The ESC OFF warning lamp å in the
instrument cluster goes out. The message
ESC-ON appears in the multifunction
display.
EBP
GObserve Safety notes, see page 61.
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
the rear brakes to supply a greater proportion
of the braking effort in straight-line braking
without a loss of vehicle stability.
GWarning!
If the EBD malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.
Adaptive Brake
Adaptive Brake provides a high level of
braking safety as well as increased braking
comfort. Adaptive Brake takes driver and
vehicle characteristics into consideration,
thus achieving an optimal braking effect.
In addition, Adaptive Brake provides the hill-
start assist system (Y page 293).
For more information on the brake system,
see (Y page 349).
Trunk Wing
GObserve Safety notes, see page 61.
The Trunk Wing enhances the vehicle’s
driving stability. It adapts the aerodynamics
of the vehicle to the driving conditions
according to the speed.
Trunk Wing switch : should be used for
cleaning only, see “Trunk Wing”
(Y page 360). It is not needed for Trunk Wing
operation.
The Trunk Wing extends at a vehicle speed of
above 75 mph (120 km/h) automatically.
Trunk Wing switch : flashes for as long as
the Trunk Wing extends. It remains
illuminated in red when the Trunk Wing is fully
extended.
