- After closing the boot lid, always check that
the catch has engaged properly. The boot lid
could otherwise open suddenly when the ve­
hicle is moving - this could result in an
acci­

dent.
- Always make sure that no-one is in the boot
lid's area of movement (especially near the
hinges) when it is moving. Risk of severe in­
juries to fingers or hands!
- The boot lid must always be completely
closed when the vehicle is moving; other­
wise toxic exhaust fumes can be drawn into
the interior.
- If
a
luggage rack (e.g. a bicycle carrier) is at­
tached to the boot lid, the boot lid may not
open completely or may move downwards
by itself due to the added weight. For this

reason,
make sure you support the boot lid

or
take the luggage off the carrier before
opening the boot lid - risk of injury!
© Note
- When towing a trailer* the automatic open
function can only be operated via the re­
lease catch on the boot lid.
- If the battery is low, the boot lid can still be
opened and closed manually; however, this
will require more effort. If
you
move the
boot lid slowly less effort will be required.
- When the vehicle is locked, you can unlock
the boot Lid separately by pressing the

button on the remote control key. The boot
lid will Lock automatically when you close it

again.

Heating and cooling

cS5
Air recirculation mode
In air recirculation mode, the air from the interi­
or of the vehicle is filtered and recirculated. This
setting prevents fumes etc. from entering the in­
terior. We recommend switching on the air recir­
culation mode when driving through a tunnel or
in traffic queues
•=>
A-
The air recirculation mode is switched off when
the control is in the defrost position

Qjp
Rear window heating
If the rear window heating is activated with the
ignition switched on, the battery management
determines whether or not the vehicle battery
charge level is sufficient for the rear window
heating to be switched on. Otherwise the rear
window heating operates when the engine is
run­

ning,
and switches off automatically after about
10 - 20 minutes, depending on the outside
tem­

perature.
To switch on the rear window heating perma­
nently, press and hold the
CÛJD
button for at least
2 seconds. This setting will be stored for approxi­
mately 15 minutes after the ignition is switched

off.

J
Seat heating*
When you press the
«0
button, the seat heating is
switched on at level 3 (the highest level). The
LEDs indicate the temperature level. To reduce
the temperature, press the button again. To
switch off the seat heating, press the button re­
peatedly until all the LEDs have gone out.
The seat heating automatically switches from
level 3 to level 2 after about 10 minutes.
(7) CAUTION
To avoid damaging the heating elements of
the seat heating, please do not kneel on the
seat or apply sharp pressure at
a
single
point

© Note
- The setting for the driver's seat heating is
assigned to the key in use.
- If the front passenger's seat heating was on
when you Last switched off the ignition, it
will be switched on automatically only if the
ignition is switched on again within 10 mi­

nutes.

/K
WARNING
- For reasons of safety you should not Leave
the air recirculation switched on for too

long.
This mode prevents fresh air from en­
tering the vehicle, so the windows can mist
over if the air cooling* is switched off. Bad
visibility can cause an accident.
- People with limited capacity to feel pain or
sense temperature could burn themselves
when using the seat heating. These people
must not use the seat heating - risk of in­
jury!
