Air outlets
Fig. 141 Dash panel: Location of air outlets
The air outlets ⇒ Fig. 141 3
and 4 can be operated as follows:
Outlets 3
and 4
–
The outlets can be opened and closed by turning the left
thumbwheels.
– The direction of air delivery from the outlets can be varied as re-
quired 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 manual-
ly, 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 5
.
Note
The cool air provided by the air conditioner is mainly issued from outlets 3
and 4. To ensure adequate cooling, outlets 3 and 4 should therefore
never be closed completely. 
Air distribution
The automatically-programmed air distribution can be al-
tered manually.
The buttons 
,  and  can be operated either separately or in combi-
nation. To return to automatically controlled air distribution, switch off the

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 air conditioner
Economical use of the air conditioner will help save fuel.
Engine power is reduced and fuel consumption increases when the
air conditioner is in cooling mode. To ensure that the system is on-
ly switched on when it is really necessary, please note the follow-
ing 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 amount of pollutants emitted from your
vehicle. 
Key settings
When the ignition is switched on, the air conditioner set-
tings assigned to the key are selected automatically.
The air conditioner settings selected are automatically stored and assigned
to the key in use. When the vehicle is started, the air conditioner automati-
cally selects the settings assigned to the key. Hence, every driver automati-
cally obtains his/her preferred settings without having to select them man-
ually.
Note
Should another driver use the key and enter other settings, the previous
settings will be deleted. 
Solar-powered blower/sunroof*
If the vehicle is parked in sufficiently strong sunlight, the
blower will operate in solar-powered mode when the igni-
tion is switched off.
After the ignition is switched off, the blower is supplied with electrical pow-
er from the sunroof. Please ensure that outlets 3 and 4 are open ⇒ Fig. 141
to ensure the best possible ventilation.
The blower only works when the sunroof is closed or tilted open at the rear. 

Air conditioning
If the air recirculation mode is on when you switch off the engine, the air
conditioner will automatically switch to fresh air ventilation. 
Auxiliary heater*
Diesel vehicles are fitted with an auxiliary heater 1)
to raise the temperature
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 auxiliary heater can be can be switched off by brief-
ly pressing the 
button on the air conditioner. Seat heating*
The surface and backrest of the front seats can be electrical-
ly heated.

Checking and refilling levels
WARNING (Continued)
● If any tests have to be performed with the engine running, there is an
added safety risk from the rotating parts (e.g. drive belts, alternator, ra-
diator fan, etc.) and from the high-voltage ignition system.
● Observe the following additional warnings if work on the fuel system
or the electrical system is necessary:
–Always disconnect the battery.
– Do not smoke.
– Never work near open flames.
– Always keep an approved fire extinguisher immediately available.
CAUTION
When topping up fluids, make sure the correct fluid is put into the correct
filler opening. This can otherwise cause serious malfunctions or engine
damage.
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected at the workshop.
● When the external temperature and level of humidity are high or when
the engine stops, it is possible for water to drop from the air conditioning
system evaporator potentially forming a small puddle on the ground. This is
normal and does not indicate a leak.
Note
On right-hand drive vehicles some of the reservoirs mentioned below are lo-
cated on the other side of the engine compartment. Closing the bonnet
–
To close the bonnet, push it down until it overcomes the spring
pressure.
– Let the bonnet engage in the locking part. Do not force it ⇒ 
.
WARNING
● For safety reasons the bonnet must always be completely closed
when the vehicle is moving. After closing it always check that it is proper-
ly secured. The bonnet must be flush with the adjacent body panels.
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet. Fail-
ure to do so could result in an accident.

Engine oil General notes
The engine is factory-filled with a special multi-grade oil that can be used all
year round.
As the use of high quality oil is essential for the correct operation of the en-
gine and its long useful life, when topping up or replacement is necessary
use only those oils that conform to the requirements of the VW standards.
The specifications (VW standards) set out in the following page should ap-
pear on the container of the service oil; when the container displays the
specific standards for petrol and diesel engines together, it means that the
oil can be used for both types of engines. 
