Never tamper with electronic components
and their software.
SRS (Supplemental Restraint System)
The SRS reduces the risk of occupants com-
ing into contact with the vehicle's interior in
the event of an accident. It can also reduce
the forces to which occupants are subjected
during an accident.
The SRS consists of:
R The 6 SRS warning lamp
R belt tensioners
R belt force limiters
R airbags
The 6 6 SRS warning lamp The SRS functions are checked regularly
when you turn on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The
6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or not be
deployed in the event of an accident with
heavy braking.
A malfunction has occurred if the 6SRS
warning lamp:
R does not light up when you switch on the
ignition
R does not go out after the engine has been
running for a few seconds
R lights up again once the engine is running
In this case, have SRS checked immediately
at a qualified specialist workshop. Triggering of belt tensioners, belt force
limiters and airbags In the event of a collision, the airbag control
unit evaluates important physical data such
as duration, direction and force of the vehicle
deceleration or acceleration. Based on the
evaluation of this data and in the event of lon-
gitudinal deceleration in a collision, the airbag
control unit pre-emptively triggers the belt
tensioners, depending on the rate of deceler-
ation, in the first stage.
i
The front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
Your vehicle has adaptive, dual stage front
airbags. When the first activation threshold is
reached, the front airbag is filled with enough
propellant gas to reduce the risk of injuries.
The front airbag is only fully inflated if a sec-
ond threshold is reached within a few milli-
seconds, due to the control unit having detec-
ted further deceleration.
Criteria for triggering belt tensioners and
airbags
In the first stage of a collision, the airbag con-
trol unit evaluates the duration and direction
of vehicle acceleration or deceleration in
order to determine whether it is necessary to
trigger the belt tensioner and/or airbag.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc-
ess is pre-emptive in nature as the airbag
must be deployed during – and not at the end
of – the collision.
i Airbags are not deployed in all types of
accidents. They are controlled by complex
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbag deployment must take place during
the impact and must be adapted to provide Occupant safety

Remove the key from the ignition lock.
X Press button :.
Indicator lamp ;lights up briefly.
X Lock the vehicle using the key. Vehicles
with KEYLESS GO* can also be locked by
touching the door handle on the outside.
Tow-away protection remains deactivated
until:
R
the vehicle is unlocked again.
R a door is opened and closed again.
R the vehicle is locked again. Interior motion sensor*
If the interior motion sensor is primed, a vis-
ual and audible alarm is triggered when move-
ment is detected in the vehicle interior while
the vehicle is locked. This occurs, for exam-
ple, if someone breaks the side windows of
your vehicle or reaches into the vehicle's inte-
rior.
Priming the interior motion sensor X
Make sure that:
R
the side windows are closed.
R the sliding/tilting sunroof* or panorama
sliding sunroof* is closed.
R there are no objects, e.g. mascots, hang-
ing on the rear-view mirror or on the roof
grab handles.
This will prevent false alarms.
X Lock the vehicle using the key. Vehicles
with KEYLESS GO* can also be locked by
touching the door handle on the outside.
The interior motion sensor is primed after
approximately 30 seconds.
Deactivating the interior motion sensor When you unlock your vehicle using the key
or KEYLESS GO*, the interior motion sensor
is automatically deactivated. To prevent a false alarm, deactivate the inte-
rior motion sensor if you lock your vehicle
and:
R
people or animals remain in the vehicle.
R the side windows remain open.
R the sliding/tilting sunroof* or panorama
sliding sunroof* remains opened. X
Remove the key from the ignition lock.
X Press button :.
Indicator lamp ;flashes briefly.
X Lock the vehicle using the key. Vehicles
with KEYLESS GO* can also be locked by
touching the door handle on the outside.
The interior motion sensor remains deacti-
vated until:
R the vehicle is unlocked again.
R a door is opened and closed again.
R the vehicle is locked again. Anti-theft systems

Convenience opening: press and hold the
g button for a second until the side win-
dows and the sliding/tilting sunroof*/pan-
orama sliding sunroof* have reached their
original position.
The indicator lamp above the gbutton
goes out. Air-recirculation mode is deacti-
vated.
i If you open the side windows or the slid-
ing/tilting sunroof* or panorama sliding

convenience closing feature, they will
remain in this position when opened using

The "residual heat" function is only available
with Thermotronic luxury 3-zone automatic
climate control*.
It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the temperature that has
been set.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the "residual heat" function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
i It is possible that the "residual heat" func-
tion may be activated automatically an hour
after the key is removed. The vehicle is then
ventilated for 30 minutes to dry the air con-
ditioning system.
X Turn the key to position 0in the ignition
lock or remove it.
X To switch on: press theÌbutton.
The indicator lamp above the Ìbutton
lights up. X
To deactivate: press theÌbutton.
The indicator lamp above the Ìbutton
goes out.
i The residual heat automatically switches
off after around 30 minutes or if:
R the ignition is switched on
R the battery voltage drops Switching the auxiliary heating/ven-
tilation* on/off
Notes on the auxiliary heating/ventila-
tion system 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 stations or when your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
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 using the vehicle's
fuel. For this reason, the tank content 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 Air conditioning
