110Climate controlTo open or close the centre air ventsand direct the flow of air, tilt the slats
up or down and turn the adjuster
wheel left or right.
Side air vents
To open or close the side air vents, tilt the slats up or down.
Direct the flow of air by rotating the
vents.
Depending upon the position of the
temperature control, air will be
directed into the vehicle via the side
air vents.
Rear air vents
Depending on vehicle, additional
adjustable air vents are located in the
rear passenger compartment.
Fixed air vents Additional air vents are located
beneath the windscreen and door
windows, in the foot wells and,
depending on vehicle, in the rear
passenger compartment.
Glovebox cooler
The air conditioning system can also
keep the contents of the glovebox
cool.Maintenance
Air intake The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.

146Vehicle care
We recommend the use of the same
grade of engine oil that was used at
the last change.
The engine oil level must not exceed
the maximum mark MAX on the
dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.
To prevent spillage when
replenishing the engine oil, we
recommend using a funnel to top-up the engine oil. Ensure funnel is
securely located onto the filler pipe.
After topping-up, put the funnel into a
plastic bag and stow it securely.
A stabilization of the engine oil
consumption will not take place until the vehicle has been driven several
thousand miles. Only then can the
actual degree of consumption be
established.
If consumption exceeds more than
0.5 litres every 600 miles after this
running-in period, consult a
workshop.
Capacities 3 195.
Fit the cap on straight and tighten it.Engine air filter
Engine air flow indicator
On certain models, an indicator is
located in the engine induction
system and indicates if the air-intake
to the engine is restricted.
Clear:No restrictionRed tell-tale:Restricted
If the red tell-tale is displayed when
the engine is running, consult a
workshop.
