Tyre monitoring system
Introduction
This chapter contains information on the followingsubjects:
⇒ Tyre Pressure Loss Indicator 
⇒ Troubleshooting for Tyre Pressure Loss Indicator 
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.

⇒ Tyre
pressure . If the tyre pressure is too low, it is possible that the tyre temperature will increase to such
an extent that the tread peels off and the tyre bursts.
⇒ Tyre pressure .

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⇒Introduction 
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.

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.

Textiles, microfibre cloth, leatherette:
Remove any dirt with Volkswagen Genuine interior cleaning agent (- 000 096 301 -). Never treat
materials with leather care agents, solvents, wax polish, shoe cream, stain removers or similar
substances.
icles adhering to surfaces: remove with a vacuum cleaner on a regular basis so that the
material is not permanently damaged by abrasion.

Natural leather:
Remove fresh soiling with a cotton cloth and mild soap solution1). Do not allow fluids to seep into
the seams.
Treat any dried stains with Volkswagen Genuine leather cleaner (- 000 096 323 -).
Regularly and each time after having finished cleaning, apply care cream with light protection and
impregnating properties. Use a special coloured leather cream if necessary. If the vehicle is parked
outdoors for long periods, you should cover the leather to protect it from direct sunlight.
Never treat leather with solvents, wax polish, shoe cream, stain removers or similar.

Plastic parts:
Use a soft, moist cloth.
If stubborn soiling cannot be removed with mild soap solution1), use a solvent-free plastic cleaning
agent if necessary, e.g. Volkswagen Genuine plastic cleaner (- 000 096 314 -).
Trim parts, trim strips made of chrome, aluminium or stainless steel:

Anodised surfaces: do not use chrome cleaning products.
Controls:
Remove coarse dirt and other dirt that is difficult to reach using a soft brush. Then use a clean, soft
cloth and a mild soap solution1). Do not allow liquids to enter the controls.
Displays:
Use a Volkswagen Genuine cleaning cloth (- 000 096 166 A -) with a little water, a suitable glass
cleaner or LCD cleaner. Do not clean displays with a dry cloth.

Repairs and technical modifications must always be carried out according to Volkswagen
specifications⇒ .
Modifications and repairs to the front bumper, doors, front seats, headliner or the bodywork should
be carried out only by a qualified workshop. Airbag system components and sensors might be fitted
on these vehicle components.
If you work on the airbag system or remove and install parts of the system when performing other
repair work, parts of the airbag system may be damaged. The consequence may be that, in the event
of an accident, the airbag inflates incorrectly or does not inflate at all.
Regulations must be observed to ensure that the effectiveness of the airbags is not reduced and that
removed parts do not cause any injuries or environmental pollution. Qualified workshops are
familiar with these regulations.
Any modifications to the vehicle's suspension could prevent the airbag system from working
properly during a collision. For example, using wheel rim/tyre combinations that have not been
approved by Volkswagen, lowering the suspension or making modifications to the suspension rate
including work on the springs, struts and shock absorbers etc., could change the forces that are
measured by the airbag sensors and sent to the electronic control unit. Some changes to the
suspension could cause the forces measured by the sensors to increase, for example. This can lead
to the airbag system being triggered in collision scenarios where it normally would not be triggered if
modifications to the suspension had not been made. Other modifications can cause the forces
measured by the sensors to decrease, therefore preventing the airbag system from being triggered
when it should have been.

WARNING
Incorrect repairs and modifications can cause malfunctions and damage to the vehicle and impair
the effectiveness of the airbag system. This can result in accidents and serious or even fatal injuries.

WARNING
Modifications to the vehicle's suspension, including the use of unsuitable tyre/rim combinations, can
cause the airbag system to function differently and increase the risk of serious or fatal injuries in the
event of an accident.
