● Never drive on if tyres or wheel rims are damaged. Seek expert assistance instead.
● If there is no visible damage, drive slowly and cautiously to the nearest suitably qualified workshop in order to have the vehicle
checked. Volkswagen recommends using an authorised Volkswagen repairer.
The Tyre Pressure Loss Indicator warns the driver when the tyre pressures are too low.
The Tyre Pressure Loss Indicator is a Tyre Pressure Monitoring System and uses data from the ABS sensors and other functions to check
the speed of rotation and the rolling circumference of the individual wheels when the vehicle is in motion.
If a tyre loses air or the tyre pressure is too low, the rolling circumference decreases and the speed of rotation increases.
The Tyre Pressure Loss Indicator shows a change in rolling circumference of the tyres with the indicator lamp in the instrument
cluster.
The following situations can also lead to a change in the speed of rotation:
—If the tyre pressure has been changed.
—If the tyre has structural damage.
—If the vehicle is loaded more heavily on one side.
—If snow chains have been fitted.
—If one wheel per axle has been changed.
The Tyre Pressure Monitoring System 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 chains.
The recommended tyre pressure for the tyre sizes approved by Volkswagen for the vehicle type can be found on the tyre pressure
sticker on the driver’s door pillar (→ Tyre pressure).
The Tyre Pressure Loss Indicator does not work if there is a fault in the ESC or ABS (→ Brake support systems).
Reference pressure
The reference pressure for the Tyre Pressure Monitoring System is the recommended tyre pressure for cold factory-fitted tyres. The
reference pressure corresponds to the information on the tyre pressure sticker (→ Tyre pressure).
If the tyre pressure of all four tyres has been adjusted correctly, the Tyre Pressure Loss Indicator must be re-synchronised (→ Tyre
Pressure Loss Indicator). This adjusts the reference pressure to the current tyre pressure.
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 correct tyre pressure must be determined.
As an additional safety feature, the vehicle is equipped with a Tyre Pressure Monitoring System (TPMS) where an indicator lamp for low
tyre pressure lights up if the pressure in one or more of the tyres is much too low. If the indicator lamp for low tyre pressure lights up,
you should therefore stop the vehicle as quickly as possible, check the tyres, and inflate them to the correct pressure. Driving with a
tyre pressure that is much too low will lead to the tyre overheating and can damage the tyre. A tyre pressure that is too low also
reduces the fuel efficiency and service life of the tyre tread and can negatively affect the driving behaviour and braking capability of
the vehicle.
The Tyre Pressure 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 Pressure Monitoring System does not give
any warning that the tyre pressure is too low.
The Tyre Pressure Monitoring System additionally has a fault indicator that issues a warning if the system is not functioning properly.
This fault indicator is coupled with the indicator lamp for low tyre pressure. If the system detects a fault, the indicator lamp flashes for
around 1 minute when the vehicle is started and then lights up continuously. This sequence is then repeated each time the vehicle is
started as long as the fault is present.
If the Tyre Pressure Monitoring System indicates a malfunction, the tyre pressure cannot be monitored correctly. A malfunction of the
Tyre Pressure Monitoring System 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 indicator lamp is indicating a system malfunction to ensure that the Tyre Pressure Monitoring System is
functioning properly (→ Tyre Pressure Loss Indicator) .
