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-
cr e

ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged, so as to maintain good visibility of everything
outs
ide.
● The m

aximum heat output required to de-
fros
t 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
syst
em, fresh 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 cooling 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 requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● If y

ou suspect 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

pecialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and t

emperature 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
winds
creen 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 int
erior and is 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 w
indows 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, a
s smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour. » 137

Heating
M ax
imum he
at output, which is needed to
defrost the windows quickly, is only available
when the engine has reached its operating
temperature.
Coolant system
When the air conditioning is switched on, the
temperature and the air humidity go down.
This way, if the outside humidity is extreme,
the air conditioning prevents the misting of
the windows and therefore, comfort is im-
proved.
If the air conditioning does not work, this
may be due to the following reasons:
● The engine is stationary.
● The fan blower is switched off.
● The outside temperature is lower than ap-
prox
imately +3°C (+37°F).
● The air conditioning system compressor
has
been temporarily switched off because of
an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioning c
hecked by a specialised work-
shop. Air recirculation
 Air recirculation prevents unpleasant smells,
e.g. when p
a

ssing through a tunnel or in
queuing traffic, from entering the interior.
If the rotary switch C

ways be open (button light off).
If the rotary switch C is switched from any
pos ition t

o the thaw position, recirculation
will be automatically deactivated.
Connecting the recirculation
In any position of rotary switch C except

air into the vehicle interior is always
from the outside. WARNING
In air recirculation mode, no cold air from the
outs ide ent

ers the vehicle interior. If the air
conditioner is switched off, the windows can
quickly mist over. Therefore, never leave the
air recirculation mode switched on for a long
time (risk of accident). Note
● When eng agin

g reverse gear, the air recir-
culation is connected automatically to pre-
vent the entrance of exhaust gases in the ve-
hicle on travelling backwards. The control
lamp on the button  does not light up.
● If the temperature control is turned to the
co l

dest setting (blue point) and the A/C but-
ton i s
on, the “Air recirculation” function is
automatically activated in order to cool the
vehicle faster using less energy, and its func-
tion control lamp will light up.

terior temperature.
It is possible to select interior temperatures
from +16°C (+64°F) to +29°C (+84°F). In this
range the temperature is regulated automati-
cally. If a temperature below +16°C (+64°F) is
selected, “LO” is displayed on the screen. If a
temperature above +29°C (+84°F) is selected,
“HI” is displayed on the screen. At both ex-
tremes, Climatronic works at maximum cool-
ing or heating power, respectively. The tem-
perature is not regulated.
In the event of prolonged, irregular distribu-
tion of the air flow from the outlets (particu-
larly the footwells) and significant differen-
ces in temperature, e.g. on leaving the vehi-
cle, sensitive people may catch cold. Air recirculation Air recirculation prevents unpleasant smells,

Introduction The power steering is not hydraulic but elec-
tromec
h

anical. The advantage of this steer-
ing is that it foes not need flexible hydraulic
pipes, hydraulic oil, pump, filter or other
parts. The electromechanical system saves
fuel. Whereas a hydraulic system needs con-
tinuous oil pressure, electromechanical
steering only needs power when it is used.
In vehicles with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running. WARNING
If the power steering does not work, you will
need much mor e s

trength to turn the wheel.
This has a considerable effect on vehicle
safety.
● The power steering only works when the
engine is
running.
● Never allow the vehicle to move when the
engine is
switched off.
● Never remove the key from the ignition
while the
vehicle is moving. The steering lock could be engaged and vehicle steering would
not w
ork. Note
The ignition of the vehicle being towed must
be sw itc

hed on to prevent the steering wheel
from locking and also to allow the use of the
turn signals, horn, windscreen wipers and
washers. Control lamp
The control lamp should light up for a few

Seek specialist assistance. WARNING
If the warning lamps and the corresponding
mes s

ages are ignored when they light up, the
vehicle may stall in traffic and cause acci-
dents and severe injuries.
● Never ignore the warning lamps or messag-
es.
● Stop the

vehicle at the next opportunity
and in a safe p
lace. Note
Failure to heed the control lamps and corre-

ext messages when they light up
may result in damage to the vehicle. Information relating to different vehi-
cl

ocesses. In order to make the vehicle more difficult to
st

al, you should always lock the steering be-
fore leaving the vehicle.
Mechanical steering lock
The steering column is locked when the key
is removed from the ignition lock and the ve-
hicle is stationary.
Activating the steering lock
● Park the vehicle ››
›

page 149.
● Remove the ignition key.
● Turn the steering wheel slightly until the
steerin
g lock has engaged.
Deactivating the steering lock
● Turn the steering wheel slightly to release
the lock.
● Inser

t the key in the ignition lock.
● Hold the steering wheel in this position
and switc
h on the ignition. Electromechanical steering
In vehic

les with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running.
You should take into account that you will
need considerably more power than normal
to steer the vehicle if the power steering is
not working correctly or at all.
Power-assisted steering
Power-assisted steering helps the driver in
critical situations. In counter-steering, it as-
sists by applying additional torque ››› .
WARNING
Power-assisted steering, together with the
ESC, help s

the driver to control vehicle steer-
ing in critical situations. However, the driver
is ultimately responsible for steering the ve-
hicle at all times. Power-assisted steering
does not remove this responsibility. 146
