The ESC or the TCS/TC can only function properly if all four wheels have the same tyres.
Any differences in the rolling radius of the tyres can cause the system to reduce engine power
unexpectedly.
If the ABS fails, the ESC, TCS, TC and EDL will also cease to function.
Control processes running in the systems described may cause operating noises.
Brake fluid

First read and observe the introductoryinformation and safety warnings⇒
Introduction
Brake fluid will gradually absorb water from the surrounding air. The brake system will be damaged
if there is too much water in the brake fluid. The boiling point of the brake fluid is also considerably
reduced by the water content. Heavy use of the brakes may cause a vapour lock in the brake
system if the water content is too high. Vapour locks reduce levels of braking power, considerably
increase braking distance and can even cause the brake system to fail completely. Your own safety
and that of other road users depends on having a brake system that functions properly at all times
⇒.
Brake fluid specification
Volkswagen has developed a brake fluid that has been optimised for the brake system in the
vehicle. To ensure optimal operation of the brake system, Volkswagen recommends the use of
brake fluid compliant with VW standard 501 14.
Driving fast on icy, slippery or wet roads can lead to a loss of control of the vehicle and could
cause serious injury to the driver and passengers.

Cleaning wheels
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Cleaning steel wheels
An industrial cleaner is needed to remove accumulated brake dust. Steel wheels should therefore
be cleaned regularly with a separate sponge.
Any damage to the paint on steel wheels should be touched up before the metal starts to rust.
Caring for and cleaning alloy wheels
Wash grit and brake dust from alloy wheels approximately every 2 weeks. Then use an acid-free
detergent to clean the wheels. Volkswagen recommends applying a hard wax compound to the
wheels approximately every 3 months.
It is important to remove road salt and brake dust by washing the wheels at regular intervals,
otherwise the finish will be impaired.
Always use an acid-free detergent for alloy wheels. Car polish or other abrasive agents should not
be used on the wheels.
If the protective coating is damaged, e.g. by stone impact, the damaged area should be repaired
immediately.
Care of rubber seals
First read and observe the introductoryinformation and safety warnings⇒
Introduction

Rims
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The design of the wheel bolts is matched to the rims. If different rims are fitted, the correct wheel
bolts with the right length and correctly shaped bolt heads must be used. This ensures that the
wheels are fitted securely and that the brake system works properly ⇒ Changing a wheel.
For technical reasons, it is not generally possible to use the wheels from other vehicles. This can
also apply to wheels of the same vehicle type.
The tyres and rims approved by Volkswagen are specifically matched to the characteristics of the
vehicle and make a major contribution to good road holding and safe handling.
Wheel bolts
Wheel bolts must always be tightened with the correct tightening torque ⇒ Changing a wheel.
Rims with bolted-on rings
Rims with bolted-on rings consist of several components. These components are fastened using
special bolts and special fastening technology. This ensures that the wheel functions properly, does
not leak, remains safe and runs true. For this reason, damaged rims should be replaced. They may
only be repaired by a qualified workshop. Volkswagen recommends using a Volkswagen dealership
for this purpose ⇒.
Rims with bolted-on trims
Rims may have removable trims that are attached to the rim with self-locking bolts. Damaged trims
may only be repaired by a qualified workshop. Volkswagen recommends using a Volkswagen
dealership for this purpose ⇒.
Rims identification
In some countries, new rims are legally required to contain certain specifications on them.
Depending on the country the following specifications can appear on the rims:
\f

Event data recorder
The vehicle is not fitted with an event data recorder.
Event data recorders temporarily store vehicle information. This provides precise information in the
event of an accident. In vehicles with an airbag system, data that might be relevant in the event of
an accident can be stored, e.g. impact speed, belt buckle status, seat positions and trigger speed.
The scope of the data is manufacturer-specific.
An event data recorder may only be fitted if the owner has approved the procedure. This is covered
by legislation in some countries.
Reprogramming control units
All data for the control of components are stored in the control units. Some convenience functions,
such as lane change flash, single door unlocking and displays, can be reprogrammed using special
workshop equipment. If this is the case, the descriptions in your vehicle wallet will no longer
correspond with the original functions. Volkswagen recommends that you have any reprogramming
confirmed in the service schedule under Workshop comments.
Information about possible reprogramming can be obtained from the Volkswagen dealership.
Reading the vehicle's event memory
A diagnostic interface for reading the event memories is located in the vehicle interior ⇒. Data
relating to the function and status of the electronic control units are stored in the event memory.
Additional information on the stored data is available from qualified workshops.
The diagnosis interface is located behind near the fuse box in the footwell on the driver side.
The event memory should only be read and reset by a qualified workshop.
After a fault has been rectified, the information in the memory pertaining to the fault is deleted.
Other memory content is overwritten on an on-going basis.
Using a mobile telephone in the vehicle without a connection to the
external aerial
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Both during telephone calls and in standby mode, mobile telephones transmit and receive radio
waves, which may also be termed "high-frequency energy". Current scientific literature warns us
that radio waves can be harmful to human beings if they exceed certain limits. Government bodies
and international committees have introduced threshold values and guidelines to ensure that
electromagnetic radiation produced by mobile telephones does not pose a hazard to health.
However, there is no proven scientific evidence that demonstrates that cordless telephones are
absolutely safe.
For this reason, some experts are calling for more precautions to be taken in the use of mobile
telephones, by taking steps to reduce the level of personal exposure to electromagnetic radiation.
If a mobile telephone that is not connected to the vehicle's external aerial is used inside the vehicle,
the level of electromagnetic radiation could be higher than when the mobile telephone is connected
to an integrated aerial or any other external aerial.
If the vehicle is fitted with a suitable hands-free unit which enables the use of innumerable
additional functions of Bluetooth compatible mobile telephones, this will satisfy the legal
requirements in many countries which permit the use of a mobile telephone in a vehicle only if a
hands-free unit is used.
The hands-free system of the portable navigation device (delivered by VolkswagenyfLQ\RXUYHKLFOH
has been developed for mobile telephones that are compatible with Bluetooth⇒ Portable
navigation device. Mobile telephones must be located in a suitable telephone holder or be stored
securely in the vehicle. If a telephone holder is used it must be securely attached to the base plate.
This is the only way to ensure that the mobile telephone is securely attached to the dash panel and
always within reach of the driver. Depending on the hands-free system, the connection between the
mobile telephone and the external aerial is established either via the telephone holder or via an
existing Bluetooth connection between the mobile telephone and the vehicle.
Connecting the mobile telephone is to a telephone aerial integrated in the vehicle or to an external
telephone aerial reduces the electromagnetic radiation generated by the telephone which could
affect the human body. Using an aerial also improves the quality of the signal.
Incorrect use of the diagnostic interface can cause faults, which can result in accidents and
serious injuries.
