– The outlets can be opened and closed by turning the left thum- bwheels.
– The direction of air delivery from the outlets can be varied as required using the adjuster in the centre of each outlet grille. The
direction of air flow can be adjusted horizontally and vertically as
desired.The flow of air from the outlets is controlled either automatically or manually,
depending on the operating mode selected. All the outlets can provide air
that is either heated, unheated or cooled.
The heater outlets for the rear footwells are located under the front seats.
They are controlled together with outlets .
Note
The cool air provided by the climate control is mainly issued from outlets
and . To ensure adequate cooling, outlets and should therefore
never be closed completely.Air distribution

Heating, Ventilation and Air conditioning
160Each of the three buttons has a specific function. The numbers relate to the
air outlets ⇒ page 159, fig. 135.
Air directed to windows
This setting directs all the air to outlets 1 and 2. Unlike in setting , the
volume of air delivery remains the same.
Air to the driver/front passenger
All the air comes from outlets 3 and 4 in the dash panel and from the rear of
the centre console.
Air to the footwells
Most of the air emerges from outlets 5 and the outlets under the front seats.
Some of the air will also be issued from outlets 3 and 4.
Note
In all of the above air distribution settings, a small amount of air will still
come from the other outlets.Economical use of the climate control
Economical use of the climate control will help save fuel.Engine power is reduced and fuel consumption increases when the
climate control is in cooling mode. To ensure that the system is only
switched on when it is really necessary, please note the following
points:
– Select ECON mode if you wish to save fuel.
– Select ECON mode if you decide to open the windows or sun roof* while driving. – If the vehicle has heated up after standing in the sun, open the
windows and doors for a short time to cool the vehicle.
For the sake of the environment
By saving fuel you also reduce the am ount of pollutants emitted from your
vehicle.Key settings
When the ignition is switched on, the climate control settings
assigned to the key are selected automatically.The climate control settings selected are automatically stored and assigned
to the key in use. When the vehicle is started, the climate control automati-
cally selects the settings assigned to the key. Hence, every driver automati-
cally obtains his/her preferred settings without having to select them manu-
ally.
Note
Should another driver use the key and enter other settings, the previous
settings will be deleted.

Solar-powered blower/solar roof*
If the vehicle is parked in su fficiently strong sunlight, the
blower will operate in solar-powered mode when the ignition
is switched off.After the ignition is switched off, the blower is supplied with electrical power
from the solar roof. Please ensure that outlets 3 and 4 are open ⇒page 159,
fig. 135 to ensure the best possible ventilation.
The blower only works when the sun roof is closed or tilted open at the rear.
If the air recirculation mode is on when you switch off the engine, the climate
control will automatically switch to fresh air ventilation.Supplementary heating*Diesel vehicles are fitted with supplementary heating
2) to raise the tempera-
ture of the interior as quickly as possible. At outdoor temperatures below
+5°C and with the engine running, the supplementary heating will switch on
and off automatically depending on the temperature of the coolant.
In order to save fuel, the supplementary heating can be can be switched off
by briefly pressing the button on the climate control.
Seat heating*
The surface and backrest of the front seats can be electrically
heated.Turn thumbwheel or ⇒fig. 136 to switch on and adjust the
heating on the left or right front seats.The heating is switched off when the thumbwheel is set to 0. The temperature
settings range from 1 to 6.
Caution
To avoid damaging the heating elements of the seat heating, please do not
kneel on the seat or apply sharp pressure to a single point.

Practical tips
Te c h n i c a l D a t a
the brake assist system automatically boosts the braking force to the
maximum level, up to the point where the anti-lock brake function (ABS) inter-
venes to stop the wheels from locking. You should then keep the brake pedal
pressed until the vehicle has braked to the required speed. The brake assist
system switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunction in the
ABS.or in the ESP.
WARNING
Please remember that the accident risk always increases if you drive too
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. An increased accident risk cannot be
compensated even by the brake assist system. Risk of accident.Electronic differential lock (EDL)
The electronic differential lock prevents the loss of traction
caused if one wheel starts spinning.General notes
The electronic differential lock (EDL) helps the car to start moving, accelerate
and climb a gradient in slippery conditions where this may otherwise be diffi-
cult or even impossible.
How it works
The EDL works automatically, i.e. without the driver's involvement. With the
aid of the ABS sensors, the system monitors the rotational speed of the
driven wheels
⇒page 176. If a considerable difference in revs is detected
(approx. 100 rpm) in the speed of the driven wheels, e.g. when only one part
of the surface supporting the wheels is slippery, the system applies the brake
to slow down the skidding wheel so that more of the power is directed to the other wheels. The systems works up to a speed of approx. 80 km/h. The
system will make noises while it is working.
Moving away from a standstill
If one wheel has less grip and starts spinning (for instance, if one of the
driven wheels is on ice), keep pressing the accelerator gradually until the car
starts moving.
Overheating of the brakes
To prevent the brake disk of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. In this case, the vehicle will
continue to run and will have the same
running properties as those of another
without EDL.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•
When accelerating on a uniformly slippery surface (for instance all four
wheels on ice or snow), press the accelerator gradually and carefully.
Despite EDL, the driven wheels may otherwise start to spin. This could
impair the car's stability. Risk of accident.
•
Even with EDL, you should always ad just your speed to suit the condi-
tions. Do not let the extra safety features tempt you into taking any risks
when driving. Failure to do so could result in an accident.Note
If the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Please take the vehicle to a specialist garage as soon as possible.

Driving and the environment
182your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.•
Never let the brakes “slip” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
•
Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
•
Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This impairs the braking effect.
•
Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the relevant instructions
before purchasing accessories ⇒ page 206, “Technical modifications”.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish with too much engine oil ⇒page 215. – Never tow the vehicle to start it, use jump leads if necessary
⇒page 271.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest qualified workshop. In general, the exhaust warning lamp will light
up when any of the described symptoms occur ⇒page 66. If this happens,
unburnt fuel can enter the exhaust system and escape into the environment.
The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Fire hazard!•
Never park where the catalytic convert er could come into contact with
dry grass or inflammable materials under the vehicle.
•
Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system. These materials could catch fire when the vehicle is being driven.Caution
Never fully drain the fuel tank because the irregularity of the fuel supply may
cause ignition problems. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust under some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be solved
by changing to another fuel brand.
WARNING (continued)

Driving and the environment
184Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumptio n does not regularise until having
driven some four kilometres. This is the reas on why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up by
as much as 5 %. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all through the year: they will increase fuel consump-
tion by up to 10 %.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your car will use about 12%
more fuel as a result of the extra wind resistance caused by the roof carrier
even when it is not in use. Saving electrical energy
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is al
so increased. Because of this, always
turn off electrical equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.

Seat belts cleaning
A dirty belt may not work properly.Check all seat belts regularly and keep them clean.
Seat belts cleaning
– Pull the dirty seat belt right out and unroll it.
– Clean dirty seat belts with a gentle soap solution.
– Allow it to dry.
– Do not roll the seat belt up until it is dry.If large stains form on the belts, it wi ll not retract correctly into the automatic
belt retractor.
WARNING
•
Do not use chemical cleaning agents on the seat belts, as this can
impair the strength of the webbing. Ensure that belts do not come into
contact with corrosive fluids.
•
Check all seat belts condition at regular intervals. If you notice that the
belt webbing, fittings, retractor mechanism or buckle of any of the belts is
damaged, the belt must be replaced by a specialist workshop.
•
Do not attempt to repair a damaged seat belt yourself. The seat belts
must not be removed or modified in any way.Caution
After cleaning, allow seat belts to dry completely before rolling them up.
Otherwise, the belt retractors could become damaged.

Wheels and tyres
232Anti-puncture tyres*
Anti-puncture tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.Vehicles equipped with anti-puncture
4) tyres from the factory indi-
cate the loss of tyre pressure on the instrument panel.
Driving with anti-puncture tyres (emergency gear)
– Leave the ESP/TCS (electronic stabilisation programme) switched on, or switch on ⇒page 68.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESP/TCS intervening often, smoke coming from the tyres or the smell of rubber, the vehicle vibrating or a clat-
tering noise. If any of these occur, stop the vehicle.
The anti-puncture tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should be
checked in a specialist workshop to detect possible damage and replace it if necessary. We recommend you contact Technical Service. If more than one
tyre is being used under emergency conditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
At the moment the loss of tyre pressure is indicated on the instrument panel,
at least one of the tyres is running in an emergency state
⇒.
End of emergency operation
Do not drive on if:
•
smoke is coming from one of the tyres,
•
there is a smell of rubber,
•
the vehicle vibrates,
•
there is a rattling noise.
When is it no longer possible to co ntinue driving even using anti-puncture
tyres?
•
If the Electronic Stabilisation Program (ESP) is out of operation.
•
If the tyre pressure monitoring system is out of operation.
•
If one of the tyres has been severely damaged in an accident, etc. If a tyre
has been badly damaged there is a risk that parts of the tread can be thrown
off and cause damage to the fuel lines, brake pipes or fuel filler.
•
It is also advisable to stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle is
considerably impaired.•
The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.
•
Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.
