Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at
regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not go out after a few seconds with the
engine running
R lights up again while the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG OFF indicator
lamp PASSENGER AIR BAG OFF indicator lamp
:is
part of the automatic child seat recognition on
the front-passenger seat.
A permanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger front airbag is disabled.
Depending on the person in the front-passenger seat, the front-passenger front airbag must
either be disabled or enabled; see the following
points. You must make sure of this both before
and during a journey.
R Children in a child restraint system:
whether the front-passenger front airbag is
enabled or disabled depends on the installed
child restraint system, and the age and size of the child. Therefore, it is imperative to
observe the notes on "Children in the vehicle"
(Y page 49). There you will also find infor-
mation on rearward or forward-facing child
restraint systems on the front-passenger
seat.
R All other persons: the PASSENGER AIR BAG
OFF indicator lamp must be off. Be sure to
observe the notes on "Seat belts"
(Y page 38) and "Airbags" (Y page 42).
There you can also find information on the
correct seat position.
Observe the information on automatic child seat recognition in the front-passenger seat
(Y page 51). Seat belts
Introduction A correctly worn seat belt is the most effective
means of restraining the movement of vehicle
occupants in the event of a collision or if the
vehicle overturns. This reduces the risk of vehi- cle occupants coming into contact with parts of
the vehicle interior or being ejected from it. The
seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag being deployed.
The seat belt system consists of:
R seat belts
R belt tensioners for the front seat belts and the
outer seat belts in the rear
R belt force limiters for the front seat belts and
the outer seat belts in the rear 38

Important safety notes
G
WARNING
Bulbs, lamps and plug connectors can
become very hot during use. When replacing a bulb, you could burn yourself on these com-
ponents. There is a risk of injury.
Allow these components to cool down before replacing the bulb.
Vehicles with static LED headlamps:
Do not use a bulb that has been dropped or if its glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps designed
for that purpose. Only fit spare bulbs of the same
type and the specified voltage.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.

Have the bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop. Headlamps and lights are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly.
Vehicles with Intelligent Light System
The front and rear light clusters of your vehicle
are equipped with LED light bulbs. Do not
replace the bulbs yourself. Contact a qualified
specialist workshop, which has the necessary

Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating and the exhaust gas dis-
charge location can be found in front of the right- hand front wheel.
! Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of two times, drive for a longer distance. 132
Operating the climate control systemClimate control

i
Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the vehicle
interior to the set temperature. This occurs with- out using the heat of the running engine. The
auxiliary heating is operated directly 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 automatically
adjusts to changes in temperature and weather conditions. For this reason, the auxiliary heating
could switch from ventilation mode to heating
mode or from heating mode to ventilation mode.
The auxiliary heating switches off automatically after 50 minutes. This time limit can be altered.
To do this, visit a qualified specialist workshop.
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
(Y page 139).
X Set the desired temperature.
Auxiliary heating or auxiliary ventilation can also
be switched on if the manually set climate con-
trol is activated. Optimum comfort is attained by setting the system to automatic mode. Set the
temperature to 22 †.
The auxiliary heating or auxiliary ventilation can
be switched on/off using the button on the
centre console or the remote control.
The on-board computer can be used to specify
up to three departure times, one of which may
be preselected (Y page 226). Switching the auxiliary heating/venti-
lation on or off using the button on the
centre console The colours of the indicator lamps in button
:

lation on or off using the remote control General notes
Your vehicle comes with one remote control.
You may use two additional remote controls for your vehicle. For more information, please con-
tact a qualified specialist workshop.
Store the remote control for the auxiliary heat-
ing so that the auxiliary heating cannot be
switched on unintentionally. In particular,
ensure that the remote control for the auxiliary
heating is kept out of the reach of children.
