Occupant safety
40 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
occupants and the area of deployment of
the airbag.
R do not place any objects between the
seat backrest and the door.
R do not hang any hard objects, for exam-
ple coat hangers, on the grab handles or
coat hooks.
R do not attach accessories, e.g. cup hold-
ers, to the doors.
It is not possible to rule out a risk of injuries
caused by an airbag due to the high speed
at which the airbag is required to deploy. G
Risk of injury
The airbag's functionality can only be guar-
anteed if the following parts are not cov-
ered and no badges or stickers are
attached to them:
R padded steering wheel boss
R front-passenger front airbag cover
R outer side of front seats
R side panel next to the rear seat backrest G
Risk of injury
When an airbag deploys, a small 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 dif-
ficulties, 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
interior. The powder does not constitute a
health hazard and does not indicate that
there is a fire in the vehicle. G
Risk of injury
The airbag parts are hot after the airbag has
been deployed. Do not touch them; other-
wise, you may burn yourself.
Have the airbags checked at a qualified
specialist workshop. Otherwise, occupants
are not protected by the airbags in the
event of another accident.
Front airbags
The front airbags are designed to increase
protection for the driver's and front-
passenger head and chest. The driver's front airbag and front-passenger
front airbag 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
deployment can offer additional protection
to that provided by the seat belt
R if the seat belt is fastened
R independently of other airbags in the vehi-
cle
R if the vehicle overturns, but only if the sys-
tem detects high vehicle deceleration in a
longitudinal direction 1

Seats
63Seats
Points to remember
You can find information about enlarging the
luggage compartment (folding forwards/
removing the rear seats) on (Y page 149).
Depending on the vehicle's equipment, the
seats can be adjusted either manually or elec-
trically. G
Risk of injury
The seats can be adjusted when the key is
removed and the door is open. For this rea-
son, children should never be left unsuper-
vised in the vehicle. They could become
trapped when adjusting a seat. G
Risk of accident
Only adjust the driver's seat when the vehi-
cle is stationary. You will otherwise be dis-
tracted from the road and traffic conditions
and you could lose control of the vehicle as
a result of the seat moving. This could
cause an accident. G
Risk of injury
Make sure that nobody can become trap-
ped when you adjust the seat. Observe the notes concerning the airbag
system.
Secure children as recommended; see
"Children in the vehicle" section.
! When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.
i The front seats are fitted with active head
restraints (Y page 42). For this reason, it is
not possible to remove the head restraints
from the front seats.
The rear-compartment head restraints can
be removed (Y page 66).

Centre for more information. Adjusting the seat manually

Risk of accident
Only adjust the driver's seat when the vehi-
cle is stationary. You will otherwise be dis-
tracted from the road and traffic conditions
and you could lose control of the vehicle as a result of the seat moving. This could
cause an accident.
G
Risk of accident
Only adjust the steering wheel when the
vehicle is stationary and do not pull away
until the steering wheel adjustment mech-
anism is locked in position. Otherwise, you
might drive without the steering wheel
adjustment mechanism being locked in
position and be distracted from road and
traffic conditions by an unexpected move-
ment of the steering wheel and cause an
accident.
However, the steerability of the vehicle is
not affected.
X Check whether seat 3and the head
restraint are adjusted properly
(Y page 63).
Make sure that:
R you are as far away from the driver's front
airbag as possible
R you are sitting in a normal upright posi-
tion
R you can fasten the seat belt properly
R you have moved the backrest to an
almost vertical position Controls

Air conditioning
128 Air conditioning
Overview of air-conditioning systems
The vehicle is equipped with one of the following air-conditioning systems: Heatmatic
16 Air-conditioning system* Thermotronic*
Heatmatic is a heating and ventilation system
without a cooling system. The air conditioning combines a heating and
ventilation system with a cooling system. The Thermotronic automatic air-conditioning
system combines an automatic heating and
ventilation system with a cooling system. You
can control the air conditioning separately for
the driver's and front-passenger sides.

Air conditioning
129General notes
The air-conditioning system*/
Thermotronic* controls the temperature and
the humidity of the vehicle interior and filters
out undesirable substances from the air.
Heatmatic/the air-conditioning system*/
Thermotronic* is only operational when the
engine is running. Optimum operation is ach-
ieved only when you drive with the side win-
dows and panorama louvred sliding sun-
roof* closed. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 84). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and completely filters out pol-
len. A clogged 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 Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the settings recommended on the
following pages. Otherwise, the windows
could mist up. This may obstruct your view
of the traffic situation and, as a result, you
may cause an accident. Cont
