Fron
tairbags The fron
tairbags increase protection for the
driver's and front-passenger's head and
chest. Driver's airbag
:deploys in front of the
steering wheel; front-passenger airbag ;
deploys in front of and above the glove com-
partment.
They are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deploymen tcan offer additional protection
to that provided by the seat belt
R if the seat belt is fastened
R independently of other airbag sinthe vehi-
cle
If the vehicle overturns, the front airbags are
generally not deployed unless the system
detects high vehicle deceleration in a longi-
tudinal direction.
Front-passenger airbag ;is only deployed if
the front-passenger seat is occupied or if the
4 PASSENGER AIRBAG OFF indicator
lamp in the centre console is not lit
(Y page 48). This means that a child
restraint system with automatic child seat
recognition has not been fitted to the front-
passenger seat or has been fitted incorrectly.
! Do not place heavy objects on the front-
passenger seat. This could cause the sys-
tem to identify the seat as being occupied.
In the event of an accident, the restraint systems on the front-passenger side are
triggered. Have restraint systems that have
been triggered replaced.
Driver's kneebag i
The driver's kneebag is only available in
certain countries.
The driver's kneebag increases protection of
the driver against:
R knee injuries
R thigh injuries
R lower leg injuries Driver's kneebag
:is always deployed along
with the driver's airbag and inflates under-
neath the steering column.
Sidebags G
Risk of injury
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Ben zvehicles.
The seat covers must have a special tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and
would fail to provide the intended protection
in the event of an accident. Appropriate seat
covers can be obtained, for example, from a
Mercedes-Benz Service Centre. 38
Occupant safetySafety
The rear-compartmen
tseat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again.
You can also cancel the rear seat belt status
indicator immediately (Y page 215).
i The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
!
If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupan tis
reduced.
The front beltf orce limiters are synchronised
with the front airbags, which take on a part of
the deceleration force. Thus, the force exer-
ted on the occupant is distributed over a
greater area. The belt tensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 35).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in the
front.
The belt tensioners on the seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The belt tensioners are triggered depending
on the type and severity of an accident:
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R in the event of a side impact, on the side
opposite the impact if the vehicle deceler-
ates or accelerates rapidly in a lateral direc-
tion
R in certain situations if the vehicle overturns
and the system determines that it can pro-
vide additional protection
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. G
Risk of injury
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations. Occupant safety

visor on the front-passenge rside.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.
Automatic child seat recognition on the
front-passenger seat If your vehicle does not have automatic child
seat recognition 2
on the front-passenger
seat, this is indicated by a special sticker .The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door. The automatic child seat recognition sensor
system on the front-passenger seat detects
whether a special Mercedes-Ben zchild seat
with automatic child seat recognition has
been fitted there. In such cases, 4
PASSENGER AIRBAG OFF indicator lamp :lights up. The front-passenger airbag is disa-
bled. G
Risk of injury
If the 4 PASSENGER AIRBAG OFF indica-
tor lamp does not light up when the child
restraint system is fitted, the front-passenger
airbag has not been disabled. If the front-
passenger airbag deploys, the child could be
seriously or even fatally injured.
Proceed as follows:
R do not use a rearward-facing child restraint
system on the front-passenger seat.
R fit a rearward-facing child restraint system
on a suitable rear seat.
or
R only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. a cushion, under the child
restraint system. The entire base of the child
restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries.
i If the front-passenger airbag is disabled
by the automatic child seat recognition, the
following remain enabled on the front-
passenger side:
R the sidebag
R the pelvisbag
R the windowbag
R the belt tensioner
2 Vehicles without automatic child seat recognition on the front-passenger seat: if you turn the key to position
2int he ignition lock, the 4PASSENGER AIRBAG OFF indicator lamp lights up briefly but has no function.
It does not indicate that there is automatic child seat recognition on the front-passenger seat. 48

Important safety notes It is advisable to have batteries replaced at a
qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre. G
Risk of poisoning
Batteries are toxic and contain caustic sub-
stances. For this reason, keep batteries out of
the reach of children.
If a battery has been swallowed, visi tadoctor
immediately. H
Environmental note Batteries contain pollutants.
It is against the law to dis-
pose of them with the house-
hold rubbish. They must be
collected separately and
recycled in an environmen-
tally responsible manner. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop, e.g. a
Mercedes-Benz Service
Centre, or to a special col-
lection point for old batter-
ies.

Important safety notes G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling station sorwhen your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
i Switch on the auxiliary heating regularly,
e.g. for about ten minutes every month. The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated directly using the
vehicle's fuel. For this reason, the tank con-
tent must be at least at reserve fuel level to
ensure that the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
The auxiliary heating switches off automati-
cally after 50 minutes. This time limit can be
altered. To do this, visit a qualified specialist
workshop, e.g. a Mercedes-Ben
zService
Centre.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before switching on X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the climate control is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. Set the temperature to 22 †.
The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 210). Operating the climate control system
