Seats and storage
Before you purchase any accessories, always read and follow the
information in=> page 341, "Additional accessories and parts
replacement".
& WARNING
• Use care when using the cigarette lighter. Inattentive or unsu­
pervised use of the cigarette lighter can cause burns -risk of
injury!
• The cigarette lighter works when the ignition is switched off or
with the ignition key removed . Children should never be left unsu­
pervised in the vehicle, or there could be risk of fire!
• The power outlets and therefore the electrical accessories
connected to them operate only with the ignition on. Improper use
of the outlets or of electrical accessories can lead to serious inju­
ries or cause a fire. For this reason, children should never be left
unattended in the vehicle -they could be injured!
0 Note
• To avoid damaging the socket, only use plugs that fit properly .
• Only use the cigarette lighter socket as a power source for elec­
trical accessories for short durations . Use the sockets* in the
vehicle when a power source is needed for longer durations.
[ i] Tips
When the engine is off and accessories are still plugged in and are
on, the vehicle battery can still be drained .•
Storage
General overview
There are numerous places to store items in your vehicle.
Glove compartment => page 89
Storage compartment in the roof =>
page 89
Coat hooks => page 89
- -Storage in the trim panels in the luggage
compartment
& WARNING
• Always remove objects from the instrument panel. Any items
not put away could slide around inside the vehicle while driving or
when accelerating or when applying the brakes or when driving around a corner .
• When you are driving make sure that anything you may have
placed in the center console or other storage locations cannot fall
out into the footwells. In case of sudden braking you would not be
able to brake, depress the clutch or accelerate.
• Any pieces of clothing that you have hung up must not interfere
with the driver's view. The coat hooks are designed only for light­
weight clothing. Never hang any clothing with hard, pointed or
heavy objects in the pockets on the coat hooks . During sudden
braking or in an accident - especially if the airbag is deployed -
these objects could injure any passengers inside the vehicle . •

The climate controls are a combination of heating, ventilation and
cooling sys tems, which automa tica lly reduce humidity and cool the
air inside your vehic le .
The climate contro l automatically maintains a temperature once it
has been set. The temperature of the air from the vents, fan speed
(air volume) and air distribution are also automatica lly adjusted. The
system also takes into account strong sunsh ine so that manual
adjustment is not necessary . So in almost all cases,
a ut oma tic mode
offers the best co nditions for the comfort of the occupants at all
times of the year~
page 99.
Please note the following :
Turn on the air conditioner to reduce hum idity in the veh ic le. This
a lso prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
c onden sation from the evaporator may drip under the vehicle . T his
is normal and does no t indicate a leak.
If the outside temperature is low, the fan norma lly on ly switches to
a higher speed once the engine coo lant has warmed up sufficiently .
The air conditioner temporarily switches off when you drive off from a standstill using fu ll throttle to save engine power .
The compressor also switches off if the coolant temperature is too high, so that the engine can be adequately cooled under extreme
loads.
Du st and poll en filte r
The dust and pollen filter (a combined particle filter and activated
cha rcoal fi lter) reduces or prevents outside air pol lut ion (dust, or
pollen) from entering the vehic le .
The dust and pollen filter must be changed at the intervals specified
in your Maintenance booklet, so that the air conditioner can prop­
erly work .
I f you drive your vehicle in an area with a high degree of a ir pollu­
tion, the filter may need to be changed more frequent ly than speci-

Energ y mana gement
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts o f
energy are temporarily cut back or switched off~
page 241.
Hea tin g systems in particu lar req uire a great dea l of energy. I f you
notice, for examp le, that the rear window heater is not heating, then
it has been temp orarily cut back or switched off by
energy manage ­
ment .
These systems are available again as soon as the energy
balance has bee n res tored .
& WARNING
Redu ced vi sibilit y is dangerou s and c an cau se a ccidents .
• For safe driving it is very important th at all windows be free of
ice , snow and conden sation .
• Completely familiari ze yourself with the proper use and fun c­
tion of the heating and ventilation sy stem and e speci ally how to
defog and defrost the windo ws.
• Never use the wind shield wiper /w asher sy stem in freezing
