Warning lamp for coolant
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Several warning and indicator lamps will light up briefly as a functional check when the ignition is
switched on. They will switch off after a few seconds.
Lit upPossible causeSolution
Engine coolant temperature is
too low in vehicles with natural
gas engine.
Avoid high engine speeds and heavy engine loads.
FlashesPossible causeSolution
Coolant temperature too high.
Do not drive on!
Stop the vehicle as soon as possible, and when
safe to do so. Switch off the engine, leave the
engine to cool down.
Coolant level too low.
Do not drive on!
After the engine has cooled down, check the
coolant level and refill engine coolant if the level is
too low ⇒ Checking the coolant level and refilling

First read and observe the introductoryinformation and safety warnings⇒
Introduction
The electrolyte level of the vehicle battery should be checked regularly in high-mileage vehicles, in
hot countries and in older vehicle batteries. The vehicle battery is otherwise maintenance-free.
Vehicles with a start/stop system ⇒ Pull-away assist systems are fitted with special vehicle
batteries. For technical reasons, it might not be possible to check the electrolyte level in these
vehicle batteries.

recommends that the protective coating on the underside of the vehicle and on the running gear
should be checked regularly and repaired if necessary.
Cleaning the engine compartment
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The engine compartment of any motor vehicle is a hazardous area ⇒ Preparation for working in the
engine compartment.
The engine compartment should be cleaned by a qualified workshop. An incorrect cleaning
procedure could possibly remove corrosion protection and damage electrical components.
Furthermore, water could enter the vehicle interior directly via the plenum chamber ⇒.
If the engine compartment is very dirty, we recommend that you always proceed to a qualified
workshop to have it cleaned by a professional mechanic. Volkswagen recommends using a
Volkswagen dealership for this purpose.
Plenum chamber
The plenum chamber is located in the engine compartment between the windscreen and the engine
and has a perforated cover. Air from outside is drawn in from the plenum chamber and is passed
into the vehicle interior via the heating and air conditioning system.
Leaves and other loose objects must be removed from the cover of the plenum chamber at regular
intervals using a vacuum cleaner or by hand.
In the interests of environmental protection, the engine compartment should be washed only
in specially provided wash bays. This prevents toxic waste water containing oil, grease and fuel
from entering the sewerage system. In some districts, washing the engine compartment anywhere
else may be prohibited.
Cleaning and caring for the interior
Introduction
This chapter contains information on the followingsubjects:
⇒ Seat covers
⇒ Cleaning cloth seat covers, fabric trim and Alcantara upholstery
⇒ Cleaning and caring for natural leather covers
⇒ Cleaning leatherette upholstery
⇒ Cleaning stowage compartments, drink holders and ash trays
⇒ Cleaning and caring for the dash panel, wooden trims and plastic parts
⇒ Cleaning seat belts
Modern fabrics, such as dark denim, are often not colourfast. Light-coloured upholstery (soft

careful. This is not caused by a fault in the upholstery, but by the non-colourfast nature of the
garments.
Leaving stains, dirt and other deposits on the surface of vehicle components and cloth seat covers
for a long time can make it difficult to clean and treat them. Stains, dirt and deposits may become
impossible to remove, particularly if left for a long time.

Running-in
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Please follow the regulations concerning running-in new parts.
Running in a new engine
Any new engine has to be run in during the first 1,500 kilometres. During its first few hours of
running, the internal friction in the engine is greater than later on when all the moving parts have
bedded down.
The style of driving during the first 1,500 kilometres will also affect the engine quality. Even after
this time \f

Service fluids and consumables
First read and observe the introductoryinformation and safety warnings⇒
Introduction
All service fluids and consumables, e.g. toothed belts, tyres, coolant, engine oil, spark plugs and
vehicle batteries, are being constantly developed. For this reason, service fluids and consumables
should be replaced at a qualified workshop. A Volkswagen dealership is always kept up to date on
innovations.
Leaking service fluids can pollute the environment. Spilt service fluids must be collected in
suitable containers and disposed of properly and with respect for the environment.
Repairs and technical modifications
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Repairs and modifications must always be carried out according to Volkswagen specifications⇒
.
Unauthorised modifications to the electronic components or software in the vehicle may cause
faults. As the electronic components are linked together in networks, these faults may indirectly
affect the working of other systems. This can seriously impair safety, lead to excessive wear of
components, and also invalidate the type approval for the vehicle.
The Volkswagen dealership cannot be held liable for any damage caused by technical
modifications and/or work performed incorrectly.
The Volkswagen dealership cannot be held liable for any damage caused by technical
modifications and/or work performed incorrectly, nor are these covered by the Volkswagen
guarantee.
Volkswagen recommends that all repairs and technical modifications are performed by an
authorised Volkswagen dealership using Volkswagen Genuine Parts.
Vehicles with special auxiliary equipment or body parts
The manufacturer of these components must ensure that these parts (fittingsyf D G K H U H W R W K H
stipulated environmental laws and regulations, particularly the EU directive 2000/53/EC concerning
end-of-life vehicles and EU directive 2003/11/EC concerning the restriction on the marketing and
use of certain dangerous substances and preparations.
Incorrectly performed repairs or modifications to your vehicle can impair the effectiveness of
the airbags, cause faults, accidents and fatal injury.
