R
Always lean against the backrest while driv-
ing. Do not lean forwards. You may otherwise
be in the deployment area of the airbag.
R
Always secure persons less than 1.50 m tall in
suitable restraint systems. Up to this height,
the seat belt cannot be worn correctly.
If a child is travelling in your vehicle, also
observe the following notes:
R
Always secure children under twelve years of
age and less than 1.50 m tall in suitable child
restraint systems.
R
Be sure to observe the instructions and safety
notes on "Children in the vehicle"
(
Y
page 54) in addition to the manufactur-
er's operating and installation instructions for
the child restraint system.
Objects in the vehicle interior may prevent
the airbag from functioning correctly. Before
starting your journey and to avoid risks resulting
from the speed of the airbag as it deploys, make
sure that:
R
there are no people, animals or objects
between the driver and the driver's airbag
R
no accessories are attached to the vehicle
within the deployment area of an airbag, e.g.
to the steering wheel or doors
R
no heavy, sharp-edged or fragile objects are in
the pockets of your clothing. Store such
objects in a suitable place.
G
WARNING
If you modify an airbag cover or affix objects
such as stickers to it, the airbag can no longer
function correctly. There is an increased risk
of injury.
Never modify an airbag cover or affix objects
to it.
Driver's airbag
The driver's airbag deploys in front of the steer-
ing wheel. When deployed, it offers additional
head and thorax protection for the occupant in
the driver's seat.
Deployment of the belt tensioner and
the driver's airbag
Important safety notes
G
WARNING
After the airbag deploys, the airbag parts are
hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified spe-
cialist workshop as soon as possible.
G
WARNING
Pyrotechnical belt tensioners which have
been triggered are no longer operational and
therefore cannot protect as intended. There is
an increased risk of injury, possibly even fatal.
Have pyrotechnic belt tensioners which have
been triggered replaced at a qualified special-
ist workshop immediately.
Mercedes-Benz recommends that you have the
vehicle towed to a qualified specialist workshop
after an accident. This is particularly important if
a belt tensioner or an airbag has been triggered.
If the belt tensioners or airbags are deployed,
you will hear a bang, and a small amount of
powder may also be released. The
6
restraint system warning lamp lights up.
Only in rare cases will the bang affect your hear-
ing. The powder that is released generally does
not constitute a health hazard, however it may
cause short-term breathing difficulties to per-
sons suffering from asthma or other pulmonary
conditions. If it is safe to do so, you should leave
the vehicle immediately or open a window in
order to prevent breathing difficulties.
Mode of operation
During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration, such
as:
R
duration
R
direction
R
intensity
Based on the evaluation of this data, the
restraint system control unit triggers the belt
tensioner for the seat belt on the driver's seat
