Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. Country-specific differen-
ces are possible. Note that your vehicle
may not be fitted with all features descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 22). Occupant safety
Important safety notes
G
WARNING
If service work is not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety system smay no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. G
WARNING
Modifications to or work performed incor-
rectly on the following parts can result in the
restraint systems no tfunctioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, belt ten-
sioners, belt force limiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an acciden tdespite
the deceleration force being sufficien tto trig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with elec-
tronic components or their software. Seat belts, together with the Supplemental
Restraint System, SRS (Y page 39), are
complementary, co-ordinated restraint sys-
tems. They reduce the risk of injury in spe-
cific, pre-defined types of accident situations
and thereby increase occupant safety. How-
ever, seat belts and airbags generally do not
protect against objects penetrating the vehi-
cle from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 90)
R the seat belt has been fastened properly
(Y page 44)
R the airbags can inflate properly if they are
deployed (Y page 40)
R the steering wheel is adjusted properly
(Y page 90)
R the restraint systems have not been modi-
fied
An airbag increases the protection of vehicle
occupants wearing a seat belt. However, air-
bags are only an additional restraint system
which complements, but does not replace,
the seat belt. All vehicle occupants must wear
their seat belt correctly at all times, even if
the vehicle is equipped with airbags. The air-
bags are not deployed in all types of acci-
dents. For example, if the protective capacity
of correctly fastened seat belts is not
increased by deploying the airbags, the air-
bags will not deploy.
Airbag deployment only provides increased
protection if the seat belt is worn correctly.
The seat belt helps, firstly, to keep the vehicle
occupant in the best position in relation to the
airbag. Secondly, in a head-on collision, for
example, the seat belt prevents the vehicle
occupant from being propelled towards the
point of impact. 38
Occupant safetySafety

front-passenger seat, you must move the
front-passenger sea tas far back as possi-
ble.
R make sure there are no heavy or sharp-
edged objects in the pockets of clothing.
R do not lean forwards, e.g. over the cover of
the driver's/front-passenger airbag, partic-
ularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel on the outside.
This allows the airbag to be fully deployed.
You could be injured if the airbag is
deployed and you are holding the inside of
the steering wheel.
R do not lean on the doors from inside the
vehicle.
R make sure that there are no people, ani-
mals or objects between the vehicle occu-
pants and the area where the airbags are
deployed.
R do not place any objects between the seat
backrest and the door.
R do not hang any hard objects, for example,
coat hangers, on the grab handles or coat
hooks.
R do not attach accessories, e.g. cup holders,
to the doors.
It is not possible to rule out a risk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed. G
WARNING
The airbag's functionality can only be assured
if the following parts are not covered and no
badges or stickers are attached to them:
R padded steering wheel boss
R front-passenger front airbag cover G
WARNING
When an airbag deploys, a small amount of
powder is released.T he powder may cause
short-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions. In order to prevent potential breathing diffi-
culties, you should leave the vehicle as soon
as it is safe to do so. You can also open the
window to allow fresh air to enter the vehicle
interior. The powder does not constitute a
health hazard and does not indicate that there
is a fire in the vehicle. G
WARNING
The airbag parts are hot after the airbag has
been deployed. Do not touch them as you
could burn yourself.
Have the airbags replaced at a qualified spe-
cialist workshop. Otherwise, occupants are
not protected by the airbags in the event of
another accident.
Airbag deployment slows down and restricts
the movement of the vehicle occupant.
If the airbags are deployed, you will hear a
bang, and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp
lights up.
The airbag installation locations are identified
by the AIRBAG symbol.
Front airbags !
Do not place heavy objects on the front-
passenger seat. The system may then
detect that the seat is occupied and if there
is an accident, the restraint systems on the
front-passenger side could be deployed.
Have restraint systems that have been trig-
gered replaced. Occupant safety
41Safety Z

Driver's airbag
:deploys in front of the
steering wheel; front-passenge rfront air-
bag ;deploys in front of and above the glove
compartment.
The front airbags increase protection for the
driver's and front-passenger's head, neck and
chest.
They are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleratio nina
longitudinal direction
R if the system determines that airbag
deploymen tcan offer additional protection
to that provided by the seat belt
R independently of other airbag sinthe vehi-
cle
R depending on whether the seat belt is being
used
If the vehicle overturns, the front airbags are
generally not deployed. The front airbags are
deployed if the system detects high vehicle
deceleration in a longitudinal direction.
Front-passenger airbag ;is only activated if
the system determines that the front-
passenger seat is occupied. The 4
PASSENGER AIRBAG OFF indicator lamp on
the centre console does not light up
(Y page 50). This means that a child
restraint system without automatic child seat
recognition has been fitted to the front-
passenger seat, or that a child restraint sys-
tem with automatic child seat recognition has
been fitted incorrectly. Windowbags
G-Class off-road vehicles, long-wheelbase
version, are equipped with windowbags.
Windowbags
:enhance the level of protec-
tion for the head, but not chest or arms, of the
vehicle occupants on the side of the vehicle
on which the impact occurs.
Windowbags :are integrated into the side
of the roof frame and deploy in the area
extending from the front door (A-pillar) to the
rear door (C-pillar).
Windowbags :are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R regardless of whether the front-passenger
seat is occupied
R independently of seat belt use
R if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the seat belt
R independently of the front airbags NECK-PRO head restraints

head restraints from triggering correctly. Con-
sequently, the NECK-PRO head restraints 42
