Air conditioning
The LEDs on the Climatronic controls indicate that the selected function has
been activated.
In addition, the radio or radio and navigation displays mounted at factory
briefly display the current settings of the Climatronic if any are modified.
The symbols used on the radio or radio and navigation displays are the
same as the symbols used for the Climatronic controls. 
Automatic mode
In automatic mode air temperature, air flow and distribution
are automatically regulated so that a specified temperature
is attained as quickly as possible and then maintained. The temperature can be adjusted separately for the left and right
sides of the vehicle interior.
Switching on automatic mode
– Press the AUTO
⇒ 
fig. 132 button. “AUTO High” is shown on the
radio display (high fan speed).
– Press the AUTO
button again ⇒ fig. 132. “AUTO Low” is shown
on the radio display (low fan speed).
Depending upon the version and finish, the vehicle may include: When a temperature of 22 °C (72 °F) is set in automatic mode a comfortable
interior climate is quickly reached. Therefore, we recommend you not to
change this adjustment, except as necessary to suit individual preferences
or particular circumstances. The inside temperature can be set between
+18 °C (64 °F) and +26 °C (80 °F). These are approximate temperatures and
the actual temperature may be slightly higher or lower depending on the
ambient conditions.
Climatronic maintains a constant temperature. The temperature of the air
supplied to the interior, the blower speed and the air distribution are regu-
lated automatically. The system also considers the sunlight radiation, so
there is no need for manual readjustment. Therefore,
automatic mode al-
most always provides the best comfort for the vehicle occupants throughout
the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, air flow or 
or the air recirculation button
. The temperature will continue to be regulated within the parameters
manually selected by the user.
Note
There are two automatic modes:
● Automatic mode LO: This calculates the air flow for two people.
● Automatic mode HI: This calculates the air flow for more than two peo-
ple. 

Air conditioning
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 DUAL
button controls the synchronisation of the 2 Climatronic climate
zones.
When the DUAL
button is on (LED lit), the climate zone of the Climatronic is
personalised, for example: Driver side temperature 22 °C and passenger
side temperature 23 °C.
When the DUAL
button is off (LED off), the climate zone of the Climatronic is
synchronised, for example: Driver side temperature 22 °C and passenger
side temperature 22 °C.
If the DUAL
button is off and the passenger side temperature is changed,
the function is automatically activated. 
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside. – Press the button 
⇒ fig. 135
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.
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 Schedule.
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. 

Checking and refilling levels
WARNING
Only change the oil yourself if you have the specialist knowledge re-
quired!
● Before opening the bonnet, read and observe the warnings
⇒ page 230, 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 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 an Authorised Service Centre.
● 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
Coolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive. The cooling system must be filled with a mixture of water and at least 40 %
of our coolant additive G12+ or an additive with the specification TT-VW 774
F (it is dyed purple). This mixture provides the necessary freeze protection
down to -25 °C and protects the alloy parts of the cooling system against
corrosion. It also prevents scaling and raises the boiling point of the cool-
ant.
The concentration of coolant must always be at least 40% - even if freeze
protection is not required.
If greater freeze protection is required in very cold climates, the proportion
of the antifreeze additive G12+ can be increased. However, the percentage
of coolant additives should not exceed 60%, as this would reduce the
freeze protection. It would also reduce the cooling effect. A mixture with
60% additive will give antifreeze protection to approx. -40 °C.
WARNING
● The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of
the reach of children. The same applies to coolant which you have
drained off.
● The coolant additive G12+ must be added in sufficient quantities to
provide anti-freeze protection at the coldest ambient temperatures that
can be expected. At extremely cold outside temperatures, the coolant
could freeze, causing the vehicle to breakdown. As the heater would not
work either, there is a risk of freezing to death. 
