Pollution filter
The pollution filter (a combined particulate
filter and active carbon filter) serves as a bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
If the filter loses efficiency prematurely due
to use in areas reaching very high pollution
levels, the pollen filter must be changed
more frequently than stated in the Service
Schedule. WARNING
Reduced visibility through the windows in-
cre a
ses the risk of serious accidents.
● Always ensure that all windows are free of
ice and snow
, and that they are not fogged, so as to maintain good visibility of everything
outside.
●
The m ax
imum heat output required to de-
frost
windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
system, fr
esh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If the c
ooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not required. WARNING
Stuffy or used air will increase fatigue and re-
duce driver c onc
entration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air recir
culation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● If y ou s
uspect that the air conditioner is
damaged, switch it off with the A/C button to prevent further damage and have it checked
by a s
pec
ialised workshop.
● Repairs to the air conditioner require spe-
ciali
st knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and t emper
ature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
windsc
reen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle interior and i
s extracted by slots in the
luggage compartment designed for this pur-
pose. Therefore, you should avoid obstruct-
ing these slots with any kind of object.
● The air conditioner operates most effective-
ly with the windo
ws and the sliding/tilting
sunroof* closed. However, if the temperature
inside the vehicle is excessive because of the
sun, the air inside can be cooled faster by
opening the windows for a short time.
● Do not smoke while air recirculation mode
is on, as
smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour. 140
Care and maintenance
●
Befor e openin
g the bonnet, switch the en-
gine off, apply the handbrake firmly and al-
ways remove the key from the ignition.
● Allow the engine to cool before you clean
the engine compar
tment.
● Do not clean, for example, the vehicle un-
derbody, wheel arc
hes or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Failure
to comply could result in injury.
● Moisture, ice and salt on the brake system
may aff
ect braking effectiveness. Risk of acci-
dent. Directly after washing, avoid sudden
and sharp braking.
● Never touch the radiator fan. It is tempera-
ture-contr
olled and could start automatically,
even when the key is removed from the igni-
tion! For the sake of the environment
Fuel, grease and oil deposits can be removed
when the engine is w
ashed. The polluted wa-
ter must be cleaned in an oil separator. For
this reason, engine washing should be car-
ried out only by a specialised workshop or a
petrol station. Caring for the vehicle interior
C l
e anin
g plastic parts and the dash
panel –
Use a clean, damp cloth to clean plastic
parts and the d
ash panel.
– If this does not provide satisfactory results,
use a speci
al solvent-free plastic cleaning
product. WARNING
Never clean the dash panel and the airbag
module s ur
face with cleaners containing sol-
vents. Solvents cause the surface to become
porous. If the airbag triggered, plastic parts
could become detached and cause injuries. CAUTION
Cleaning products which contain solvents will
damag e the m
aterial. Cleaning wooden trim*
–
Clean the wooden trim with a water-mois-
tened c
le
an cloth.
– If this does not provide satisfactory results,
use a gentle
soap solution. CAUTION
Cleaning products which contain solvents will
damag e the m
aterial. Cleaning upholstery and fabric trim
Cloth seat covers and fabric trim on the
doors, hea
dlinin
g etc. can be cleaned with a
special interior cleaner or with dry foam and
a soft brush.
Cleaning the radio and climate con-
trol s To clean the radio and/or climate controls,
u
se a sof
t d
amp cloth. For more resistant dirt,
a neutral soap solution may be used.
Cleaning leather* Normal cleaning
–
Moisten a cotton or woollen cloth with wa-
ter and w
ipe ov
er the leather surfaces.
Cleaning stubborn stains – More stubborn dirt can be removed using a
mild soap so
lution (pure liquid soap; two
tablespoons diluted in one litre of water)
and a cloth. »
