The heating element for the rear window is located on the inner side of the
window. To prevent damage, do not put stickers over the heating elements on
the inside of the window.
Cleaning windscreen wiper bladesClean wiper blades are essential for clear vision.
1. Use a soft cloth to remove dust and dirt from the windscreen wiper blades.
2. Use window cleaner to clean the windscreen wiper blades. Use a sponge or a cloth to remove stubborn stains.Care of rubber seals
If rubber seals are well looked after, they will not freeze so
quickly.1. Use a soft cloth to remove dust and dirt from the rubber seals.
2. Apply a specialist care product to the rubber seals.The weather strips on the doors, windows, bonnet and rear lid will remain
pliable and last longer if they are treated with a suitable care product (for
example silicone spray).
Caring for rubber seals will also prevent premature ageing and leaks. The
doors will be easier to open. If rubber seals are well looked after, they will not
freeze so quickly in winter.
Door lock cylinders
The door lock cylinders can freeze up in winter.To de-ice the lock cylinders you should only use spray with lubricating and
anti-corrosive properties.Cleaning chrome parts1. Clean chrome parts with a damp cloth.
2. Polish chrome parts with a soft, dry cloth.If this does not provide satisfying results, use a specialist chrome cleaning
product . Chrome cleaning products will remo ve stains and coatings from the
surface.
Caution
To prevent scratching chrome surfaces:•
Never use an abrasive care product on chrome.
•
Do not clean or polish chrome part s in a sandy or dusty environment.
Steel wheels– Clean steel wheels regularly using a separate sponge.Use an industrial cleaner to remove brake dust. Any damage to the paint on
steel wheels should be repaired before the metal starts to rust.

Cleaning and caring for your vehicle
188Cleaning the engine compartment
Take special care when cleaning the engine compartment.Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularl y important in winter when the car is
frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after the salting period.
Your Authorised Service Centre is able to provide the correct cleaning and
preserving products and has the necessary equipment. For this reason, we
recommend having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine cleaned.
If this job is carried out, you should ensure that all surfaces, seams, joints and
components in the engine compartmen t are given anti-corrosion treatment
afterwards.
WARNING
•
When working in the engine compartment, always observe the safety
warnings ⇒ page 198.
•
Switch off the engine, apply the parking brake firmly and always
remove the key from the ignitio n before you open the bonnet.
•
Allow the engine to cool before you clean the engine compartment.
• Do not c l ean the underside of vehicle wheel arches without protecting
your hands and arms. You may cut your self on sharp-edged metal parts.
Failure to comply could result in injury.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. If possible, avoid sudden braking immediately after washing
the vehicle.
•
Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason,
engine washing should be carried out only by a qualified workshop or a suit-
able filling station.Care of the vehicle interiorCleaning plastic parts and the dash panel– Use a clean, damp cloth to clean plastic parts and the dash panel.
– If this does not provide satisfactory results, use a special solvent-free plastic cleaning product.
WARNING
Never clean the dash panel and surface of the airbag module with cleaners
containing solvents. Solvents cause the surface to become porous. If the
airbag inflates, disintegrating plastic parts can cause substantial injuries.

If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation. For
this reason, “winter-grade diesel fuel” is available in some countries during
the cold months. It can be used at temperatures as low as -22°C.
In countries with different climatic conditions the diesel fuel sold generally
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for
operation in winter. This ensures that the fuel system remains operational to
approx. -24°C, provided you use winter-grade diesel which is safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24°C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (“thinners”, or similar additives) with diesel fuel.
Working in the engine compartmentSafety instructions on working in the engine compartment

Engine oilEngine oil specifications
The engine oil used must conform with exact specifications.Specifications
The engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of high quality oil is essential for the correct operation of the
engine and its long useful life, when topping up or replacement is necessary,
use only those oils that conform to the requirements of the VW standards.
If it is not possible to find oil co nforming to the VW standards then oil
conforming to the ACEA or API standa rds with an appropriate viscosity at
atmospheric temperature should be used instead. The use of this type of oil
may have some repercussions on the performance of the engine for example,
long starting time, increased consumption and a higher emission level.
If a top up is required then different oils may be mixed as long as they all
conform to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; the container will display together
the different standards for petrol and diesel engines, the oil can be used for
both types of engines.

Note
Before a long trip, we recommend finding an engine oil that conforms to the
corresponding VW specifications and keeping it in the vehicle. This way, the
correct engine oil will always be available for a top-up if needed.Checking the engine oil level
The engine oil dipstick indicates the level of the oil.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 198.
– Park the vehicle on an even surface.
– After stopping the engine, wait a few minutes for the oil to drain back into the sump. – Raise the bonnet
⇒page 200.
– Pull out the dipstick.
– Wipe the dipstick with a cloth and insert it again, pushing it in as far as it will go.
– Pull the dipstick out again and check the oil level ⇒fig. 144.
– Replace the dipstick, pushing it in as far as it will go.
The position of the dipstick is shown in the corresponding engine compart-
ment diagram ⇒page 260.
If the oil level is in area ⇒fig. 144 , do not top up with oil.
If the oil level is in area , you may top up with oil (approx. 0.5 l).
If the oil level is in area , you must top up with oil (approx. 1.0 l).
It is normal for the engine to consum e a certain amount of oil. Consumption
can be up to 1.0 litres per 1,000 km. For this reason the engine oil level must
be checked at regular intervals, preferably when filling the tank and before a
journey.
When the engine is working hard, for instance during sustained high-speed
motorway cruising in summer, when towing a trailer or climbing on mountain
passes, the oil level should preferably be kept within area and not above
this.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.•
When working in the engine compartm ent, always observe the safety
warnings ⇒page 198.
