move the front-passenger seat as far back
as possible. This is especiallyi mportant if
you have secure dachild in achild restraint
system on the front-passenger seat.
R vehicl eoccupants –inparticular ,children
–m ust no tlean their heads into the area of
the window in which the sidebag/window-
bag is deployed.
R rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger airbag has
been disabled. On the front-passenger
seat, the front-passenger airbag is disabled
if ac hild restraint system with atrans-
ponder for automatic child seat recognition
is fitted to the front-passenger seat in a
vehicle equipped with automatic child seat
recognition. The 4PASSENGER AIRBAG
OFF indicator lamp must be continuously
lit.
If the front-passenger seat of your vehicle
does not have automatic child seat recog-
nition ,oryour rearward-facing child
restraint system does not have atrans-
ponder for automatic child seat recogni-
tion ,children must be secured in achild
restraint system on asuitable seat in the
rear. If you secure aforward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
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 fron tairbag,
particularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steerin gwheel 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 steerin gwheel.
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, e.g. coat
hangers, on the grab handles or coat hooks.
R do not attac haccessories, e.g. cup holders,
to the doors.
It is not possible to rule out arisk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed. G
WARNING
Airbag functionality can only be assured if the
following parts are not covered and no badges
or stickers are attached to them:
R padded steerin gwheel boss
R kneebag cover below the steerin gcolumn
R front-passenger airbag cover
R outer side of fron tseat bolsters
R side trim nexttot he rear seat backrest
R roof frame cover between the fron tA-pillar
and the C-pilla rinthe rea rcompartment G
WARNING
Whe nana irbag deploys, asmall amount of
powder is released .The 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 af ire 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. Occupant safety

i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tyres and
the road surface. Please pay special atten-
tion to the notes on tyres, recommended
minimum tyre tread depths, etc.
(Y page 328).
In wintry driving conditions, always use
winter tyres (M+S tyres) and, if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. ABS (Anti-lockB
raking System)
Important safety notes i
Observe the "Important safety notes" sec-
tio n(Ypage 62). G
WARNING
If ABS is faulty, the wheels could lock when
braking .The steerability and braking charac-
teristics may be severely impaired. Addition-
ally,f urther driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at aqualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 261) and
displaym essages which may be shown in the
instrumentc luster (Ypage 232). ABS regulates brake pressure in such
away
that the wheels do not lock when you brake.
This allowsy ou to continue steering the vehi-
cle when braking.
ABS works from aspeed of about 8km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently.

no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could adjust the seats and
become trapped. G
WARNING
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as aresult of
the seat moving. This could cause an acci-
dent. G
WARNING
If you adjust the seat height carelessly,y ou or
others could be trapped and thereby injured.
Children in particular could unintentionally
press the buttons to electrically adjust the
seats and become trapped.
Take care that:
R while moving the seats, your hands do not
get under the lever assembly of the seat
adjustment system.
R children in the vehicle do not slide their
hands under the levers. G
WARNING
Make sure that nobody can become trapped
when adjusting the seats.
Observe the notes on airbags.
Secure children as recommended; see the
"Children in the vehicle" section. G
WARNING
Make sure that the back of your head is sup-
ported at eye level by the central area of the head restraint. If your head is not supported
correctly by the head restraint, you could suf-
fer asevere neck injury in the event of an
accident. Never drive if the head restraints are
not engaged and set correctly. G
WARNING
As eat belt can only offer its intended degree
of protection when the backrest is almost ver-
tical and the occupant is sitting upright. Avoid
seat position sthat do not allow the seat belt
to be routed correctly. Adjust the backrest so
that it is as upright as possible. Never travel
with the backrest reclined too far backwards.
You could otherwise be seriously or even
fatally injured in the event of an acciden tor
sudden braking.

Important safety notes G
WARNING
Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
R if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by asticker The system may not recognise the following
road users:
R
road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind acrash barrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually. You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.116

WARNING
Observ ethe settings recommende donthe
following pages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 132).
i Ventilate the vehicle for abrief period
during warm weather, e.g. using the con-
venienc eopening feature (Y page 89). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observe the interval for replacing the filter, which is
specified in the Servic
eBooklet .Asit
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. 124

with air dehumidification function
Points to observe before use G
WARNING
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
Condensation may drip from the underside of
the vehicle when cooling mode is active. This
is normal and not asign that there is amal-
function.
i The cooling with air dehumidification
function uses refrigerant R134a. This
refrigerant does not contain chlorofluoro-
carbons, and therefore does not damage
the ozone layer. Operating the climate control system
