front airbag both before and during the jour-
ney.
If a person is sitting on the front-passenger
seat, this person must sit:
R with the seat belt fastened correctly
R in an almost upright position with their
back against the seat backrest
R with their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, the automatic front-passenger
front airbag deactivation system may be influ- enced, e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
The front-passenger front airbag may be dis-
abled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR
BAG OFF indicator lamp lights up perma-
nently. The front-passenger front airbag does not then deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly. Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
If the PASSENGER AIR BAG OFF indicator
lamp remains off and/or the PASSENGER AIR BAG ON indicator lamp lights up, do not install
a rearward-facing child restraint system on
the front-passenger seat. Further information can be found under "Problems with the auto-matic front-passenger front airbag deactiva-
tion system" (Y page 56). G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG ON indicator lamp is lit
This poses an increased risk of injury or even fatal injury.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle seat-belt extender to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the retracted seat-belt
extender. If necessary, adjust the front- Occupant safety

The front and rear light clusters of your vehi-
cle are equipped with LED light bulbs. Do not replace the bulbs yourself. Contact a qualifiedspecialist workshop which has the necessaryspecialist knowledge and tools to carry out
the work required.
Lamps 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. Windscreen wipers
Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when the windscreen is dry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto-
matic car wash. Windscreen wipers

control optimally.
R Activate climate control using the Ã
rocker switch. The indicator lamp in the

R Set the temperature to 22 †. R
Only use the windscreen demisting func-
tion briefly until the windscreen is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode.
R Use the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac-
tivated with the ignition switched off. The 140

Problems with the rear window heating
Problem
Possible causes/consequences and
M
MSolutions The rear window heat-
ing has switched off
prematurely or cannot
be activated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heat- ing can be activated again. Switching air-recirculation mode
on/off
General notes You can also temporarily deactivate the flow
of fresh air manually if unpleasant odours are
entering the vehicle from outside. The air
already inside the vehicle will then be recir-
culated.
If you activate air-recirculation mode, the win-
dows can mist up more quickly, in particular
at low temperatures. Only use air-recircula-
tion mode briefly to prevent the windows
misting up.
Activating/deactivating X
Turn the key to position 2in the ignition
lock (Y page 161).
X To activate: press thegrocker switch

X To deactivate: press thegrocker
switch up or down.
The indicator lamp in the grocker
switch goes out. Air-recirculation mode is deactivated auto-
matically:
R after approximately five minutes at outside
temperatures below approximately 5 †
R after approximately five minutes if "Cooling
with air dehumidification" is deactivated
R after approximately 30 minutes at outside
temperatures above approximately 5 † if
