Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 24). Panic alarm

Restraint system: introduction
The restraint system reduces the risk of vehi-
cle occupants coming into contact with parts of the vehicle's interior in the event of an
accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing systems
The components of the restraint system work
in conjunction with each other. They can only deploy their protective function if, at all times,
all vehicle occupants:
R have fastened their seat belts correctly
(Y page 44)
R have adjusted their seat and head restraint
properly (Y page 97).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (Y page 96).
You also have to make sure that an air bag can inflate properly if deployed (Y page 46).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi-
cle occupants in the event of an accident. For example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident
situation are deployed. However, seat belts
and air bags generally do not protect against objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Triggering of the Emer-
gency Tensioning Devices and air bags"
(Y page 54). 40
Occupant safetySafety

This steering assistance is provided in partic-
ular if:
R both right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
R the vehicle starts to skid.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 63).
No steering assistance is provided from
STEER CONTROL, if:
R ESP ®
is malfunctioning.
R the lighting is faulty.
If ESP ®
is malfunctioning, you will be assisted
further by the electrical power steering. Protection against theft

function or KEYLESS-GO: switch the igni-
tion off and open the driver's door.
X To deactivate: switch on the ignition.

one can start the engine if a valid SmartKey
has been left inside the vehicle.
i The immobilizer is always deactivated
when you start the engine.
In the event that the engine cannot be star- ted (yet the vehicle's battery is charged),
the system is not operational. Contact an
authorized Mercedes-Benz Center or call
1-800-FOR-MERCedes (in the USA) or
1-800-387-0100 (in Canada). ATA (anti-theft alarm system)
