Tyre pressure
Follow the trailer manufacturer's recommendations concerning the tyre pressure for the trailer
tyres.
When towing a trailer, inflate the wheels on the towing vehicle with the maximum permitted tyre
pressure Tyre pressure

WARNING
Accidents and serious injuries can occur if you exceed the vehicle's maximum permitted gross axle
weight rating, drawbar load, gross vehicle weight rating or gross combination weight rating.

exceed the permissible gross vehicle weight for the vehicle with weight at the front and rear of the
vehicle.

WARNING
Loads that may slide can severely impair stability and driving safety, which can cause accidents and
severe injuries.

secure loads using suitable and undamaged lashing, retaining or securing straps.
Driving with a trailer
First read and observe the introductoryinformation and safety warnings
Headlight adjustment
Towing a trailer can raise the front end of the vehicle enough for the dipped beam to dazzle other
road users. Use the headlight range control to lower the light cone as required. Vehicles with
dynamic headlight range control are adjusted automatically.
Things to note when driving with a trailer
If the trailer has an overrun brake, apply the brakes gently at first and then firmly. This will
prevent the jerking that can be caused by the trailer wheels locking.

Refill only with distilled water. All other types of water can cause corrosion in the engine due to
the chemical components contained in the water. This can also lead to engine failure. If any other
type of water apart from distilled water has been refilled, the fluid in the cooling system should be
completely replaced immediately by a qualified workshop.

Brake fluid

Fig. 190 In the engine compartment: cap on the brake fluid reservoir.
Brake fluid will gradually absorb water from the surrounding air over the course of time. 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 and full braking 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 expressly recommends the use of
brake fluid compliant with VW standard 501 14.
Before using a particular brake fluid, check that the brake fluid specifications printed on the
container correspond to the vehicle requirements.

standard 501 14 is available from Volkswagen dealerships.
If this brake fluid is not available and it is necessary to use another high-quality brake fluid instead,
brake fluid that is compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4 can be
used.
Not all brake fluids that are compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4
have the same chemical composition. Some of these brake fluids may contain chemicals that can
damage or destroy brake system components over time.
Volkswagen therefore recommends the use of brake fluid that is compliant with VW standard 501 14
to ensure sustained proper operation of the brake system.
Brake fluid that is compliant with VW standard 501 14 fulfils the requirements of DIN ISO 4925
CLASS 4 or US standard FMVSS 116 DOT 4.
Brake fluid level
The brake fluid level must always be between the MIN and MAX marking on the brake fluid reservoir
or above the MIN marking
The brake fluid level cannot be checked accurately in all models as engine components may partially
conceal the fluid level in the brake fluid reservoir. If the brake fluid level cannot be read exactly,
please go to a qualified workshop.
The brake fluid level drops slightly during vehicle operation as the brake pads wear and the brakes
are automatically adjusted.
Brake fluid level
The indicator lamp lights up red.
Brake fluid level is too low.
Do not drive on! Check the brake fluid level.
If the brake fluid level is too low, inform a qualified workshop. Have the brake system checked.
Changing the brake fluid
The brake fluid should be changed by a qualified workshop. Volkswagen recommends using a
Volkswagen dealership for this purpose. Only brake fluid that conforms with the required
specification should be used.

WARNING
Brake failure or reduced braking efficiency can be caused by the brake fluid level being too low or by
brake fluid that is too old or unsuitable.

NOTICE
Brake fluid that has leaked or been spilt can damage the vehicle paintwork, plastic parts and tyres.
Immediately wipe off brake fluid that has leaked or been spilt from all parts of the vehicle.

Brake fluid can pollute the environment. Any service fluids that have escaped or been spilt must be
collected and disposed of properly.

the country in which the vehicle was sold. Please ask your Volkswagen dealership for further
information.
The selling Volkswagen dealership will issue a comprehensive LongLife mobility guarantee for every
new vehicle which applies from the time of delivery until the first due inspection. If you purchase
your new vehicle directly from Volkswagen AG, Volkswagen AG will issue the LongLife mobility
guarantee from the time of delivery until the first due inspection.
Your Volkswagen dealership will extend the LongLife mobility guarantee until the following
inspection when the due inspection is carried out by the dealership. The service costs include the
entire guarantee package.
The comprehensive LongLife mobility guarantee includes the following services:
If your vehicle can no longer be driven due to a technical defect1), corresponding assistance will be
provided in the case of breakdown or accident. The LongLife mobility guarantee provides with you
protection and mobility.
The inspection is not only about car maintenance - it also ensures that your car remains roadworthy
and in perfect working order. For this reason, servicing should be carried out regularly in accordance
with the manufacturer's specifications.
Your entitlement to the LongLife mobility guarantee is documented in the digital service schedule
each time your car is serviced. A full service history shows that your car has been professionally
maintained and cared for.
1) A vehicle which can no longer be driven is a vehicle which cannot reach a workshop under its own
power.
Data storage and services
Your vehicle is fitted with electronic control units. Some of these are required to make sure your
vehicle remains safe while others provide support while driving (driver assist systems). Furthermore,
your vehicle is equipped with convenience and Infotainment functions, which are also made possible
using electronic control units.
Electronic control units contain data memories which can store information regarding the vehicle
status, component load levels, servicing requirements, technical events and faults on a temporary or
permanent basis. This information generally documents the status of a component, a module, a
system or the environment, e.g.:
. filling levels, tyre pressure, battery status.
deceleration, lateral acceleration, display of fastened seat belts.
