Even if the coolant level is correct do not continue driving. You should ob-
tain technical assistance.
WARNING
When working in the engine compartment, always observe the safety
warnings ⇒ page 235.
CAUTION
Accessories in front of the air inlet reduce the cooling effect of the coolant.
At high outside temperatures and high engine loads, there is a risk of the
engine overheating. 
Rev counter
The rev counter displays the engine speed in revolutions per
minute. The start of the red zone ⇒ Fig. 34 4
indicates the maximum engine speed
operating at service temperature. However, it is advisable to change up into
a higher gear, move the selector lever to D or lift your foot off the accelerator
before the needle reaches the red zone.
CAUTION
To prevent possible engine malfunctions, the rev counter needle should not
reach the red zone. The start of the red zone on the dial is different for some
engine versions.
For the sake of the environment
Changing up into higher gears sooner, following the recommended gear in-
dications ⇒ Fig. 40 will help you to reduce fuel consumption, emissions and
also engine noise. Speedometer
The speedometer is equipped with a digital odometer and a trip recorder, in
addition to a service intervals display.

Interior heating
– Turn the temperature selector ⇒ Fig. 131 1
clockwise to select
the required temperature.
– Turn the blower switch to one of the settings 1-4.
– Set the air distribution control to the air flow configuration de-
sired: 
(towards the windscreen),  (towards the chest), (towards the footwell) and  (towards the windscreen and
footwell areas).
Interior cooling
– Switch on the air conditioner using the button ⇒ Fig. 130 AC
.
– Turn the temperature selector anticlockwise until the desired
cooling output is reached.
– Turn the blower switch to one of the settings 1-4. –
Use the air distribution regulator to guide the airflow in the re-
quired direction 
(to the windscreen),  (to the upper body),
 (to the footwell) and  (to the windscreen and to the foot-
well).
Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves
comfort for the vehicle occupants and prevents misting of the windows
when the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons: 

163
Air conditioning
● The engine is not running.
● The blower is switched off.
● The outside temperature is lower than approximately +3 °C (+37 °F).
● The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high. ●
The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop. 
Air recirculation mode 
Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.
Fig. 132 On the dash panel: Climatic controls
Air recirculation mode ⇒ Fig. 132 
prevents strong odours in the outside
air from entering the vehicle interior, for example when passing through a
tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the vehicle rather than
the cold air from outside. With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.

168Air conditioning
Switching on manual mode
–To enter manual mode, press one of the buttons ⇒ Fig. 136 1
to 5 or press the air flow control 10. The selected function is
shown on the radio or navigator display.
Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperature is displayed above the selector. It
is possible to select interior temperatures from +18 °C (+64 °F) to +26 °C
(+80 °F). These are approximate temperatures and the actual temperature
may be slightly higher or lower depending on the ambient conditions.
If you select temperatures below +18 °C (+64 °F) the indication LO will ap-
pear on the screen. In this setting the system runs at maximum cooling out-
put and the temperature is not regulated.
If you select temperatures above +26 °C (+80 °F) the indication HI will ap-
pear on the screen. In this setting the system runs at maximum heating out-
put and the temperature is not regulated.
Blower
The air flow may be adjusted freely using the control 10
. Always have the
blower running at a low setting to ensure a constant flow of fresh air into
the vehicle. Pushing the button  to the minimum -1, turns the Climatronic
off.
Air distribution
The air distribution is adjusted using the buttons 
,  and . It is also
possible to open and close some of the air vents separately.
Switching the air conditioning on and off
When the AC
button is on (LED lit), the air conditioning system is on.
When the AC
button is off (LED off), the air conditioning system is off. When the
AC
button is off, the air conditioning system is switched off to
save fuel. The temperature continues to self-regulate. The set temperature
can then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The SYNC
button controls the synchronisation of the 2 Climatronic climate
zones.
When the SYNC
button is off (LED off), the climate zone of the Climatronic is
personalised. For example: driver side temperature +22 °C (+72 °F) and pas-
senger side temperature +24 °C (+75 °F).
When the SYNC
button is on (LED lit), the climate zone of the Climatronic is
synchronised. For example: driver side temperature +22 °C (+72 °F) and
passenger side temperature +22 °C (+72 °F).
If the SYNC
button is on and the passenger side temperature is changed,
the function is automatically deactivated. 
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside. – Press the button 
⇒ Fig. 136
2 to switch air recirculation
mode on or off. It is switched on if the following symbol appears
in the display .
Air recirculation mode prevents strong odours in the ambient air from enter-
ing the vehicle interior, for example when passing through a tunnel or in a
traffic jam.
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside. 

169
Air conditioning
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

General notes
Pollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the intervals specified in the Service Plan.
If the filter loses efficiency prematurely due to use in areas reaching very
high pollution levels, the pollen filter must be changed more frequently
than stated in the Service Schedule.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves comfort for the vehicle occupants and prevents misting of the windows
when the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
●
The engine is not running.
● The AC
button is disconnected.
● The outside temperature is lower than approximately +3 °C (+37 °F).
● The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.
CAUTION
● If you suspect that the air conditioner is damaged, switch it off with but-
ton AC
to prevent further damage and have it checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised
workshop.
Note
● If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a pud-
dle underneath the vehicle. This is completely normal and there is no need
to suspect a leak.
● Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over.
● The air from the vents flows through the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects. 
Safety FirstOperating instructionsPractical TipsTechnical Specifications

170Air conditioning
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the temperature inside the vehi-
cle is excessive because of the sun, the air inside can be cooled faster by
opening the windows for a short time.
● Do not smoke while air recirculation mode is on, as smoke drawn into
the air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
● It is advisable to connect the air conditioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, a Technical Service should be consulted to check the
system. 

208Driving and the environment
Note
● If you vehicle has Start-Stop, it is not recommended to switch this func-
tion off.
● It is recommended to close the windows when driving at more than
60 km/h (40 mph)
● Do not drive with your foot resting on the clutch pedal, as the pressure
can make the plate spin, more fuel will be used and it can burn the clutch
plate lining, causing a serious fault.
● Do not hold the vehicle on a hill with the clutch, use the foot brake or
hand brake, using the latter to start. The fuel consumption will be lower and
you will prevent the clutch plate from being damaged.
● On descents, use the engine brake, changing to the gear that is more
suitable for the slope. The fuel consumption will be lower and the brakes
will not suffer. 

212Trailer towing
Fitting a towing bracket*
It is possible to fit a towing bracket to the rear of the vehicle.
Fig. 158 Attachment points for towing bracket
If a towing bracket is to be fitted after the vehicle is purchased, this must be
completed according to the instructions of the towing bracket manufacturer.
The attachment points for the towing bracket A
are on the lower part of the
vehicle.
The distance between the centre of the ball coupling and the ground should
never be lower than the indicated value, even with a fully loaded vehicle
and including the maximum drawbar load.

Fitting a towing bracket
● Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact a Technical Service to check
whether your cooling system needs modification.
● The legal requirements in your country must be observed (e.g. the fitting
of a separate control lamp).
● Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and a power socket must be connected to the vehicle electri-
cal system. This requires specialised knowledge and tools.
● Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.
WARNING
The towing brackets should be fitted at a specialised workshop.
● If the towing bracket is incorrectly installed, there is a serious danger
of accident.
● For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.
CAUTION
● If the power socket is incorrectly installed, this could cause damage to
the vehicle electrical system. 

236Checking and refilling levels
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the
risk of accident or fire.
● Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the en-
gine to cool before carefully opening the bonnet.
● Switch off the engine and remove the key from the ignition.
● Apply the handbrake and move the gear lever to neutral or selector
lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a risk of burns.
● Never spill liquids on a hot engine or on a hot exhaust gas system.
This is a fire hazard.
● Avoid causing short-circuits in the electrical system, particularly at
the points where the jump leads are attached ⇒ page 288. The battery
could explode.
● Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
● Do not unscrew the cap on the coolant expansion tank when the en-
gine is hot. If the coolant is hot, the cooling system will be pressurised!
● Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
● Always make sure you have not left any objects, such as cleaning
cloths and tools, in the engine compartment.
● If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.WARNING (Continued)
● If any work has to be performed when the engine is started or with
the engine running, there is an additional, potentially fatal, safety risk
from the rotating parts, such as the drive belts, alternator, radiator fan,
etc., and from the high-voltage ignition system. You should also observe
the following points:
–Never touch the electrical wiring of the ignition system.
– Ensure that jewellery, loose clothing and long hair do not get trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery from the on-board network. The ve-
hicle must be unlocked when this is done, otherwise the alarm will be
triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand.
CAUTION
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage! 

242Checking and refilling levels
WARNING
Only change the engine oil yourself if you have the specialist knowledge
required!
● Before opening the bonnet, read and observe the warnings
⇒ page 235, Safety instructions on working in the engine compartment.
● Wait for the engine to cool down. Hot oil may cause burn injuries.
● Wear eye protection to avoid injuries, such as acid burns, caused by
splashes of oil.
● When removing the oil drain plug with your fingers, keep your arm
horizontal to help prevent oil from running down your arm.
● Wash your skin thoroughly if it comes into contact with engine oil.
● Engine oil is poisonous! Used oil must be stored in a safe place out of
the reach of children.
CAUTION
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
● Because of the disposal problems, the necessary special tools and spe-
cialist knowledge required, we recommend that you have the engine oil and
filter changed by a Technical Service.
● Never pour oil down drains or into the ground.
● Use a suitable container when draining the used oil. It must be large
enough to hold all the engine oil. Coolant
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25°C (-13 F) and protects the light alloy parts of the cooling system against
corrosion. It also prevents scaling and considerably raises the boiling point
of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture of distilled water and, at
least, 40 % of the G 13 or G 12 plus-plus (TL-VW 774 G) additive (both are
purple) to obtain an optimum anticorrosion protection ⇒ 
. The mixture of
G 13 with G 12 plus (TL-VW 774 F), G 12 (red) or G 11 (green-blue) engine
coolants will significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒ 
. 
