Luggage compartment Loading the luggage compartment All luggage and other loose objects must be
safely secured in the luggage compartment.
Unsecured objects which shift back and forth
could impair the driving safety or driving
characteristics of the vehicle by shifting the
centre of gravity.
– Distribute the load evenly in the luggage
compartment.
– Place heavy objects as far forward as possi-
ble in the luggage compartment.
– Place the heavy objects first.
– Secure heavy objects to the fitted fastening
rings ›››
page 103 . WARNING
● Loose luggage and other objects in the lug-
gage compartment could cause serious inju-
ries.
● Always stow objects in the luggage com-
partment and secure them on the fastening
rings.
● Use suitable straps to secure heavy ob-
jects.
● During sudden manoeuvres or accidents,
loose objects can be thrown forward, injuring
vehicle occupants or passers-by. This in-
creased risk of injury will be further increased if a loose object is struck by an inflating air-
bag. If this happens, objects can be trans-
formed into “missiles”. Risk of fatal injury.
●
Please note that the centre of gravity may
shift when transporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Therefore, it is essential to adjust
your speed and driving style accordingly, to
avoid accidents.
● Never exceed the allowed axle weights or
allowed maximum weight. If said weights are
exceeded, the driving characteristics of the
vehicle may change, leading to accidents, in-
juries and damage to the vehicle.
● Never leave your vehicle unattended, espe-
cially when the rear lid is open. Children
could climb into the luggage compartment,
closing the door behind them; they will be
trapped and run the risk of death.
● Never allow children to play in or around
the vehicle. Close and lock all the doors and
rear lid when you leave the vehicle. Before
you lock the vehicle, make sure that there are
no adults or children in the vehicle. CAUTION
Hard objects on the boot cover could chafe
against the wires of the heating element in
the rear window and cause damage. Note
● Air circulation in the vehicle helps reduce
fogging of the windows. Used air escapes through ventilation slits in the side trim of
the luggage compartment. Ensure that these
ventilation slits are never covered.
● Straps for securing the load to the fasten-
ing rings are commercially available. Rear shelf

temperatures from +18 °C (+64 °F) to +26 °C
(+80 °F). These are approximate tempera-
tures and the actual temperature may be
slightly higher or lower depending on the
outside ambient conditions.
If you select temperatures below +18 °C
(+64 °F), the indication: LO will appear on the
screen. In this setting the system runs at
maximum cooling output and the tempera-
ture is not regulated.
If a temperature above +26 °C (+80 °F) is se-
lected, the screen will show HI. In this setting
the system runs at maximum heating output
and the temperature is not regulated. Blower

Operation
If the windscreen air output is on and air re-
circulation mode is pressed, this remains ac-
tive. When the recirculation mode is on, if the
air distribution towards the windscreen mode
is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation
mode should not be connected. WARNING
In air recirculation mode, no cold air from the
outside enters the vehicle interior. If the air
conditioning system is switched off, the win-
dows can quickly mist over. Therefore, never
leave the air recirculation mode switched on
for a long time (risk of accident). General notes
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. Air conditioner
When the air conditioning system is switched
on, not only the temperature, but also the air
humidity in the vehicle interior is reduced.
This improves comfort for the vehicle occu-
pants and prevents misting of the windows
when the ambient air humidity is high.
If the air conditioning system cannot be
switched on this may be caused by the fol-
lowing reasons:
● The engine is not running.
● The A/C button is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).
● The air conditioning system compressor
has been temporarily switched off because
the engine coolant temperature is too high.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop. CAUTION
● If you 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 specialised workshop.
● Repairs to the air conditioner require spe-
cialist knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and temperature 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
windscreen 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 is extracted by slots de-
signed for this purpose. Therefore, do not
cover these slots with items of clothing or
other objects.
● The air conditioner operates most effective-
ly with the windows 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.
● It is advisable to turn on the air condition-
ing at least once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system. 116
