Function and control
Fig. 253 In the stowage compartment on the front passenger side: button for the tyre monitoring sys-tem.
l"'"""f'n First read and observe the Introductory l.-J,.:,LL Information and safety warnings & on page 318.
The tyre monitoring system uses data from the ASS sensors and other functions to check the speed of rotation and the rolling circumference of the individual wheels. The rolling circumference of the wheels changes, if the tyre pressure is too low. This is then shown by the tyre monitoring sys-tem ill in the instrument cluster.
The operation of the tyre monitoring system is im-paired:
• If the tyre pressure has been changed manual-ly.
• If the tyre has structural damage.
• If the vehicle Is loaded more heavily on one side.
• If the wheels on one axle are loaded more heavily, e.g. high load level.
• If snow chains have been fitted.
• If one wheel per axle has been changed.
• When driving with a heavy trailer attached.
• If you are driving under winter conditions or on unsurfaced roads.
• When driving fast with hard acceleration and braking manoeuvres.
Synchronising the tyre monitoring system
The tyre monitoring system will have to be re-synchronised after changing the tyre pressure, or after changing one or more wheels. This also ap-plies for changing the wheels, e.g. from the front to the rear, and for changing from summer tyres to winter tyres.
The saved values must be reset before the system can be resynchronised.
• Switch on the ignition, and while the vehicle is stationary
• Press and hold the =>Fig. 253 button until an acoustic confirmation signal is emitted.
• OR: with some vehicle equipment options, you can open menu option Tyre pressure in the in-strument cluster display and save the new tyre pressures there =>page 24.
Once the saved values have been reset, the sys-tem calibrates itself independently to the fitted tyres and the tyre pressures filled by the driver dur-ing normal vehicle operation. The calibrated values are adopted and monitored after a long journey at various speeds.
If the wheels are loaded more heavily than normal, e.g. if the vehicle is carrying heavy payload, the tyre pressure must be raised to the recommended full-load tyre pressure before synchronisation =>page 367.
m The tyre monitoring system stops working if l!.J there is a fault in the ESC or ASS =>page 269.
m When using snow chains, an incorrect dis-l!.J play may be shown as the snow chains in-crease the tyre circumference =>page 367. Driver assist systems I 321

Displays for the Climatronic information
Depending on the vehicle equipment level, infor-mation on the Climatronic is displayed briefly on the screen of the factory-fitted radio or navigation system.
The dust and pollen filter
The dust and pollen filter with activated charcoal reduces the level of impurities in the outside air en-tering the vehicle.
The dust and pollen filler must be changed regular-ly to avoid impairing the performance of the air conditioning system.
The dust and pollen filter must be changed more frequently than stated in the service schedule if the efficiency of the filter declines prematurely due to the vehicle being used in areas with high levels of air pollution.

A WARNING
Poor visibility through all windows increases the risk of collisions and accidents, which can cause serious injuries.
• Always ensure that all windows are free of ice, snow and mist to ensure good visibility.
3221 While driving
A WARNING (Continued)
• Maximum heat output, which Is needed to defrost the windows as quickly as possible, is only available when the engine has reached Its operating temperature. Do not start your journey until you have good visibil-Ity.
• Always ensure that the heating and fresh air system or the air conditioning system and the rear window heating are used correctly so that you have good visibility.
• Never use the air reclrculatlon mode for an extended period. If the cooling system Is switched off, the windows can mist up very quickly In air reclrculatlon mode and reduce visibility considerably.
• Always switch off the air reclrculatlon mode when it Is not required.
A WARNING
Stale air can quickly make the driver tired and affect their concentration, which In turn can cause collisions, accidents and serious Inju-ries.
• Never switch off the blowers or switch on the air recirculatlon mode for an extended pe· riod as this prevents fresh air from entering the vehicle interior.
• Switch off the air conditioning system if you suspect that it has been damaged. This can help to prevent secondary damage. The air conditioning system should be checked by a qualified workshop.
• Repairs to the air conditioning system re-quire specialist knowledge and special tools. Volkswagen Commercial Vehicles recommends using a Volkswagen Commercial Vehicles deal-ership for this purpose.
• Do not insert any objects in the slots of the air outlets. This could cause damage to the air outlets.

m If the cooling system is switched off. the out-W side air that is drawn into the vehicle is not dehumidified. To prevent the windows misting over, Volkswagen Commercial Vehicles recommends that you leave the air conditioning (air conditioning co'!!E.'"essor) switched on. To do this, press the @ button. The indicator lamp in the button must light up.
m Maximum heat output, which is needed to de-W frost the windows as quickly as possible, is only available when the engine has reached its op-erating temperature.

.........r'n First read and observe the Introductory L-.lr:.ll Information and safety warnings & on page 322.
The cooling system for the vehicle interior only works when the engine is running and the blower is switched on.
The air conditioning system operates most effec-tively with the windows and the sliding/tilting roof closed. However, if the vehicle has heated up after standing in the sun for some time, the air inside can be cooled more quickly by opening the win-dows and the sliding/tilting roof for a short time.
Settings for optimal road visibility
Switching the cooling system on not only reduces the temperature of the vehicle interior, but also the humidity. This improves comfort for the vehicle oc-cupants and prevents the windows from misting when the outside humidity is high.

The cooling system cannot be switched on
The following criteria may prevent the cooling sys-tem from being switched on:
• The engine is not running.
• The blower is switched off.
• The air conditioning system fuse has blown.
• The ambient temperature is lower than approxi-mately +3"C (+38°F).
• The compressor has been temporarily switched off because the coolant temperature is too high.
• There is a different fault in the vehicle. The air conditioning system should be checked by a quali-fied workshop.
Things to note
If the humidity and temperature outside the vehicle are high, condensation can drip off the evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does not indicate a

A WARNING
Stale air can quickly make the driver tired and affect their concentration, which In turn can cause collisions, accidents and serious inju-ries.
• Never use the air reclrculation mode for an extended period as no fresh air will enter the vehicle Interior.
• If the cooling system is switched off, the windows can mist up very quickly In air recir-culatlon mode and reduce visibility consider-ably.
• Always switch off the air reclrculation mode when it is not required.
CD
In vehicles with an air conditioning system, do not smoke when the air reclrculatlon mode Is switched on. The smoke drawn Into the cooling system can leave a residue on the evaporator and the dust and pollen filter with active carbon insert, producing a lasting unpleasant odour.
