The Climatronic in automatic mode ensures the best-possible setting of the tem-
perature of the outflowing air, the blower stage and air distribution.
The system also takes sunlight into account, which eliminates the need to alterthe settings manually.
The cooling system operates only if the following conditions are met. The cooling system is switched on » page 100.
The engine is running.
The outside temperature is above approx. +2 °C.
The cooling system is switched off at a high coolant temperature in order to pro-
vide cooling at a high load of the engine.
Aeration of the vehicle when ignition is switched off
On models fitted with power sliding/tilting roof with sollar cells, the fresh air blower is automatically switched over to “solar mode” if the sun ray's are suffi-
cient after switching off the ignition. The solar cells on the sliding/tilting roof de-
liver power for the fresh air blower. This supplies the interior of the car with fresh air.
For an optimum ventilation, the air outlet vents 2 and 3 must be opened » Fig. 105
on page 99.
The ventilation functions only when the sliding/tilting roof is fully closed.
Note■ We recommend that you have Climatronic cleaned by a specialist garage once
every year.■
On vehicles equipped with a factory-fitted radio or radio navigation system, the
Climatronic information is also shown on their displays. This function can be
switched off, see » operating instructions for the radio or navigation system .

Auxiliary heating (auxiliary heating and ventilation)
Introduction
This chapter contains information on the following subjects:
Switching on/off
108
Radio remote control
109
Conditions for the functioning of auxiliary heating (Aux. heating and ventilation),
hereinafter referred to only as auxiliary heating (Aux. heating).
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon 
is not lit in the display of the
instrument cluster).
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
Auxiliary heating (aux. heating)
The auxiliary heating (aux. heating) can be used when stationary, when the en- gine is switched off to preheat the vehicle and while driving (e.g. during the heat-
ing phase of the engine).
The auxiliary heating (auxiliary heating) functions in connection with the air-con-
ditioning system or Climatronic.
The auxiliary heating (aux. heating) also warms up the engine. This is not valid for
vehicles with the 3.6 l/191 kW FSI engine.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank. The coolant heats air flowing into the passenger compart-
ment (as long as the blower fan speed
B
» Fig. 107 on page 100 or » Fig. 108 on
page 103 is not set to zero).
WARNING■ The auxiliary heating (aux. heating) must never be operated in closed rooms
(e.g. garages) – risk of poisoning!■
The auxiliary heating (aux. heating) must not be allowed to run during refu-
elling – risk of fire.
■
The exhaust pipe of the auxiliary heating (aux. heating) is located on the un-
derside of the vehicle. Therefore, if you wish to operate the auxiliary heating
(aux. heating), do not park the vehicle in such a way that the exhaust gases
can come into contact with highly flammable materials (e.g. dry grass) or easily
inflammable substances (e.g. spilt fuel) – risk of fire.
CAUTION
■ Running auxiliary heating (aux. heating) consumes fuel from the vehicle tank
and automatically controls the filling level. If only a low quantity of fuel is present in the fuel tank, the auxiliary heating (aux. heating) switches off.■
The exhaust pipe of the auxiliary heating (aux. heating), which is located on the
underside of the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating (aux. heating) is running, the vehicle battery discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometres in order to recharge
the vehicle battery.
Note
■ The auxiliary heating (aux. heating) switches on the blower B » Fig. 107 on
page 100 or » Fig. 108 on page 103 only if it has achieved a coolant temperature
of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating problem.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or leaves)
to ensure that the auxiliary heating (aux. heating) operates properly.
■
So that warm air can flow into the vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by
you, leave the fan switched on and leave the air outlet vents in an open position.
It is recommended to put the air flow in the position  or .

107Air conditioning system

The engine output falls as altitude increases, as does the vehicle's climbing pow-
er. Therefore, for every additional 1000 m in height (or part), the maximum per-
missible towed weight must be reduced by 10%.
The towed weight is made up of the actual weights of the loaded towing vehicleand the loaded trailer.
The trailer and drawbar load information on the type plate of the towing device is
merely a test value for the towing device. The vehicle-specific values are detailed in the vehicle documents.WARNING■ Do not exceed the maximum permissible axle and drawbar load and the
maximum permissible total or towed weight of the vehicle and the trailer –
risk of accident and serious injury.■
Slipping loads can significantly impair the stability and safety of the vehicle/
trailer combination – risk of accident and serious injury.

Safety eyelet
The purpose of the safety eyelet B
» Fig. 142 is to attach the breakaway cable of
the trailer.
When attaching the breakaway cable to the safety eyelet, it must sag freely
against the vehicle in all trailer positions (sharp bends, in reverse etc.).
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. The national legal requirements must be observed.
Headlights
The front of the vehicle may lift up when a trailer is being towed and the head-
lights may dazzle other road users.
Adjust the headlights using the headlight beam control » page 51, Parking and
low beam lights .
Driving speed
For safety reasons, do not drive faster than 80 km/h when towing a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the trail- er is detected. Never attempt to stop the trailer from “swaying” by accelerating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first, then brake firmly. This will avoid brake jolts resulting from
the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as a
brake.
Engine overheating
If the needle for the coolant temperature gauge moves into the right-hand area or the red area of the scale, the speed must be reduced immediately.
Stop and switch off the engine if the indicator light 
in the instrument cluster
lights up. Wait a few minutes and check the level of coolant » page 213, Check-
ing the coolant level .
The following guidelines must be observed » page 16, 

In some countries, 5.5 ltr. applies for both variants.
209Inspecting and replenishing

The oil level must be checked at regular intervals. We recommend after each time
you refuel or prior to making a long journey.
We recommend maintaining the oil level within the range A
, but not above , if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun- tain pass.
The indicator light in the instrument cluster will indicate whether the oil level is
too low » page 18 ,  Engine oil level . Check the oil level using the dipstick as
soon as possible. Add oil accordingly.
CAUTION
The oil level must not exceed the range A » Fig. 164 – there is a risk of damaging
the exhaust system.

The coolant consists of water with coolant additive. This mixture guarantees anti- freeze protection, protects the cooling/heater system against corrosion and pre-
vents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the same antifreeze written on the antifreeze expansion tank » Fig. 165 on page 213.
WARNING■
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 206.■
Do not continue your journey if for some reason it is not possible to fill with
coolant under the current circumstances . Switch off the engine and seek
assistance from a specialist garage.
CAUTION
■ The concentration of coolant additive in the coolant must never be under 40%.■Over 60% of coolant additive in the coolant reduces the antifreeze protection
and cooling effect. 212General Maintenance

■A coolant additive that does not comply with the correct specifications can sig-
nificantly reduce the corrosion protection.■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 165 on page 213.

the warning light  » page 16 ,  Coolant lighting up in the instrument cluster.
We still recommend inspecting the coolant level directly at the reservoir from
time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a specialist
garage.
Replenishing
First read and observe the introductory information and safety warn-
ings
on page 212.
Only top up with new coolant.
