Old tyres should only be replaced by tyres that have been approved by Volkswagen for the vehicle type. The Tyre Pressure Loss Indicator may react with a delay or not display anything at all in the event of a sporty driving style, when driving on snow-covered or icy roads or unpaved roads or when driving with snow chain. Do not rely only on the tyre monitoring sys- tem! Check your tyres regularly to ensure that they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove any objects that become em- bedded in the tyre tread but have not penetrated into the body of the tyre itself.
The Tyre Pressure Loss Indicator shows a change in rolling circumference of the tyres with the in- dicator lamp in the instrument cluster. The recommended tyre pressure for the factory- fitted tyres is indicated on the tyre pressure sticker on the driver's door pillar. → page 189 The tyre pressure of all tyres including the spare wheel or temporary spare wheel must be checked monthly on a cold tyre and correspond to the vehicle manufacturer's specifications on the tyre pressure sticker. If the tyre size of the mounted tyres differs from the specifications on the type plate or tyre pressure sticker, the cor- rect tyre pressure must be determined.
Tyre Pressure Loss Indicator Please refer to at the start of the chapter on page 183. The tyre monitoring system does not remove the need for regular maintenance and inspection of tyres. The driver is responsible for ensuring the correct tyre pressure is maintained at all times, even if the tyre monitoring system does not give any warning that the tyre pressure is too low. The tyre monitoring system additionally has a fault indicator that issues a warning if the system is not functioning properly. . When the vehicle is started, if the system detects a fault, The in- dicator lamp flashes for about 1 minute and then remains lit continuously. Fig. 145 On Centre console:
tyre pressure monitor- ing button Function description The Tyre Pressure Loss Indicator is a tyre moni- toring system and uses data from the ABS sen- sors and other functions to check the speed of rotation and the rolling circumference of the in- dividual wheels when the vehicle is in motion. If the tyre pressure of one or more wheels changes, the e Tyre Pressure Loss Indicator gives an alarm. If the tyre monitoring system indicates a mal- function, the tyre pressure cannot be monitored correctly. A malfunction of the Tyre Pressure Loss Indicator can have various causes, e.g. due to replacement of a wheel or tyre.
When a wheel or tyre has been replaced, check whether the warning lamp is indicating a system malfunction to ensure that the tyre monitoring system is functioning properly. → page 185 However, the following situations can also lead to a change in the rolling circumference: – If the tyre pressure has been changed. Synchronising the Tyre Pressure Loss Indicator – Switch on the ignition. – If the tyre pressure is too low. – If the tyre has structural damage. – When all four tyre pressures correspond to the required values, tap → Fig. 145 until the sys- tem emits a confirmation sound. – If the vehicle is loaded more heavily on one side. – If snow chains have been fitted.
– If a temporary spare wheel has been fitted. After an extended driving time and driving at dif- ferent speeds, the system will automatically learn the new values and monitor them. – If one wheel per axle has been changed. Owner's manual 184
