Tyre Pressure Loss Indicator
Troub
The tyre monitoring system warns the driver when the tyre pressures are too low.
The tyre monitoring system monitors various parameters (for example, rolling circumference) of all
wheels using ABS sensors (indirect measurement).

WARNING
The intelligent tyre monitoring system technology cannot overcome the laws of physics, and
functions only within the limits of the system. Incorrect handling of the wheels and tyres can lead to
a sudden loss of pressure in the tyres, tread separation and even tyre blow-out.

amage.


If the tyre pressure is too low, this will increase fuel consumption and tyre wear.

When new tyres are driven at high speeds for the first time, they can expand slightly and trigger a
one-off pressure warning.

Old tyres should be replaced only by tyres that have been approved by Volkswagen for the vehicle
type.

Do not rely solely on the tyre monitoring system. 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 embedded in the tyre tread but have not penetrated into the body of the
tyre itself.
Tyre Pressure Loss Indicator
First read and observe the introductoryinformation and safety warnings
Functional description
The Tyre Pressure Loss Indicator uses data from the ABS sensors and other functions to compare the
speed of rotation and the rolling circumference of the individual wheels.
The rolling circumference can change:

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 chains.

Troubleshooting

After a warning about the tyre pressure being too low, switch the ignition off and then back on
again. The Tyre Pressure Loss Indicator can be re-synchronised only after this has been done.

The tyres are the most heavily loaded and most underestimated parts of a vehicle. Tyres are very
important as the narrow tyre contact surfaces are the only contact between the vehicle and the
road.
The service life of tyres is dependent on tyre pressure, driving style, handling and correct fitting.

WARNING
New tyres or tyres which are old, worn down or damaged cannot provide full vehicle control and
braking efficiency.

Handling wheels and tyres

First read and observe the introductoryinformation and safety warnings

Rotating wheels
Regularly rotating the wheels as shown in the illustration Fig. 193is recommended to help ensure
that tyres wear evenly. All the tyres will then last for about the same time.
Volkswagen recommends having the wheels changed by a qualified workshop.

Tyres that are older than 6 years
Tyres age through physical and chemical processes that can impair their function. Tyres that have
been stored unused for an extended period of time age more quickly than tyres that are used all the
time.
Volkswagen recommends replacing tyres that are older than 6 years with new tyres. This also applies
to tyres which appear to still be in good condition and whose tread depth has not yet reached the
minimum value stipulated by legislation
Winter and all-year tyres also largely lose their effectiveness through ageing regardless of the
remaining tread depth.

WARNING
Wheels must have the necessary clearance. If the wheels do not have the necessary clearance, the
tyre could rub on parts of the running gear, vehicle body and the brake lines. This can lead to a fault
in the brake system and to tread separation and thus to a tyre bursting.
and must not rub on any vehicle body parts.

Avoid heavy impacts and drive round obstacles whenever possible. Tyres can be deformed by
potholes and kerb edges especially. This can cause damage to the tyres and wheel rims.

Old tyres should be disposed of as required by legislation.

Volkswagen-approved tyres are guaranteed to have the dimensions that are suitable for the vehicle.
In the case of other tyres, the tyre seller must provide a certificate from the tyre manufacturer
stating that the tyre is also suitable for the vehicle. This certificate must be stored in a safe place in
the vehicle.
Wheel rims and wheel bolts
First read and observe the introductoryinformation and safety warnings
Wheel rims, tyres and wheel bolts are matched to the vehicle type. If different wheel rims are fitted,
the correct wheel bolts with the correct length and correctly shaped bolt heads must be used.
For technical reasons, it is not generally possible to use the wheel rims from other vehicles. This can
also apply to wheel rims of the same vehicle type.
The tightening torque of the wheel bolts must be checked regularly with a properly functioning
torque wrench.
Wheel bolts
The correct wheel bolts must be used for each vehicle type; these bolts must always be tightened
with the correct tightening torque Wheel bolts
Wheel rims with bolted rim rings or trim elements
Rims with bolted-on rings or trim elements consist of several components. These components are
joined together using special bolts. Damaged wheel rims must be replaced and must always be
repaired only by a qualified workshop. Volkswagen recommends using a Volkswagen dealership for
this purpose
Wheel rim identification
In some countries, new wheel rims must contain information on certain properties. The following
information may appear on the wheel rim:
