Driving and the environmentRunning-inRunning-in a new engine
The engine needs to be run-in over the first 1,500 km.Up to 1,000 kilometres
– Do not drive faster than three quarters of top speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 km
–Speeds can be gradually increased to the maximum road speed
or maximum permissible engine speed (rpm).During its first few hours of running, the internal fric tion in the engine is
greater than later on when all the moving parts have bedded in.
For the sake of the environment
If the engine is run-in gently, the life of the engine will be increased and its oil
consumption reduced.
Running-in tyres and brake pads
New tyres should be run-in carefully for the first 500 km. New
brake pads should be run-in carefully for the first 200 km.During the first 200 km, you can compensate for the reduced braking effect
by applying more pressure to the brake pedal. If you need to make an emer-
gency stop, the braking distance will be longer with new brake pads than with
brake pads that have been run-in.
WARNING
•
New tyres do not give maximum grip to start with, and require running-
in. This may cause an accident. Drive particularly carefully in the first 500
km.
•
New brake pads must be “run-in” and do not have the correct friction
properties during the first 200 km. However, the reduced braking capacity
may be compensated by pressing on the brake pedal a little harder.
Braking effect and braking distance
The braking effect and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town traffic, drive short distances or have a sporty driving style, we
recommend that you have the thickness of your brake pads checked by an

WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•
By law, the ball coupling must be removed if a trailer is not being towed
and it obscures the number plate.
Driving tips
Driving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This applies especially when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of snaking . Never try to stop the “snaking” by increasing speed.
Always brake in good time. If the trailer has an overrun brake, apply the
brakes gently at first and then firmly. This will pr event the jerking that can be
caused by the trailer wheels locking. Select a low gear in good time before
going down a steep descent. This enables you to use the engine braking to
slow down the vehicle. Heating
At very high temperatures and during prolonged ascents, driving in a low gear
and high engine speed, always moni
tor the temperature indicator for the
coolant ⇒page 55.
Electronic Stabilisation Program*
Do not switch off the ESP* when towing a trailer. The ESP* makes it easier to
stabilise if the trailer starts to snake.
Driving economically and with respect for the
environmentGeneral notes
Fuel consumption depends largely on your personal driving
style.Fuel economy, environmental impact and wear on the engine, brakes and
tyres depend largely on three factors:•
Personal driving style
•
Conditions of use (weather, road surface)
•
Technical requirements
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%. This section
suggests methods of lessening the impact on the environment and reducing
your operating costs at the same time.

Think ahead when drivingA vehicle uses most fuel when accelera ting. If you think ahead when driving,
you will need to brake less and thus accelerate less. Wherever possible, let
the vehicle roll slowly to a stop, for instance when you can see that the next
traffic lights are red.Regular servicingBy taking your car to an Authorised Service Centre for regular servicing you
can establish a basis for good fuel economy before you start driving. A well-
serviced engine gives you the benefit of improved fuel efficiency as well as
maximum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Check the oil level every time you fill the tank ⇒page 203. Oil consumption
depends to a great extent on the engine load and engine speed. Depending
on your personal driving style, oil consumption can be up to 1 litre per 1,000
km.
Avoid short journeysThe engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions.
Directly after a cold start, the engine uses about 50-70 litres of fuel per
100 km. This figure then drops to 20 -30 litres per 100 km after about one
kilometre. The engine only reaches its working temperature after about four
kilometres, when fuel consumption will return to a normal level. You should
therefore avoid short journeys.
The ambient temperature has a decisive influence.
The illustration shows the different rates of fuel consumption for the same
distance at both +20°C and -10°C. Your vehicle will use more fuel in winter
than in summer.

tion in litres per 100 km at

•
Wait until no more steam, smoke or coolant is emitted from the bonnet,
then carefully open the bonnet.
•
When working in the engine compartment, always observe the safety
warnings ⇒ page 198.
Closing the bonnet– Raise the bonnet slightly.
– Release the bonnet stay and replace it in its support.
– At a height of about 30 cm let it fall so it is locked.If the bonnet does not close, do not pr ess downwards. Open it once more and
let it fall as before.
WARNING
If the bonnet is not closed properly, it could open while you are driving and
completely obscure your view of the road. Risk of accident.•
After closing the bonnet, always check that it is properly secured. The
bonnet must be flush with the surrounding body panels.
•
If you notice that the bonnet latch is not secured when the vehicle is
moving, stop the vehicle immediately and close the bonnet properly. Risk
of accident.
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.

New tyres
New tyres have to be run-in
⇒page 173.
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern.
Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the car pulling to one side, this may indicate that one of the tyres
is damaged. The tyres should be chec ked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•
New tyres do not have maximum grip in the first 500 km. Drive particu-
larly carefully to avoid risk of accident.
•
Never drive with damaged tyres. This may cause an accident.
•
If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required ty re inflation pressure from the sticker. The
values refer to Summer tyres. For Winter tyres, you must add 0.2
bar to the values given on the sticker.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
WARNING
A tyre can easily burst if the pressure is too low, causing an accident!•
At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
•
If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.

WARNING
There is a serious danger of accidents if a tyre bursts during driving!•
The tyres must be replaced at the latest when the tread is worn down to
the tread wear indicators. Failure to do so could result in an accident. Worn
tyres do not grip well at high speeds on wet roads. There is also a greater
risk of “aquaplaning”.
•
At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
•
If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.
•
Keep chemicals such as oil, fuel and brake fluid away from tyres.
•
Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.Puncture-proof tyres*
Puncture-proof tyres will usually allow the vehicle to continue
even when one of the tyres has a puncture.Vehicles that are factory-fitted with puncture-proof tyres
20)
indicate
on the instrument panel when there is a loss of tyre pressure. Driving on puncture-proof tyres (emergency use)
– Leave the ESP/TCS (electronic stabilisation programme)
switched on, or switch on.
– Drive carefully and at moderate speed (80 km/h maximum).
– Avoid sharp turns and rapid manouevres.
– Avoid driving over obstacles (for example, kerbs) or potholes.
– If the ESP/TCS is frequently activated, check whether there is smoke coming from the tyres or a smell of rubber, or if the vehicle
vibrates or rattles. If this is the case, stop the vehicle.
Puncture-proof tyres are marked on the tyre wall as follows: “DSST”,
“Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The tyre walls of this type of tyre are reinforced. When the tyres lose air, the
tyre walls keep the tyre up (emergency use).
Loss of air pressure in the tyre is shown on the instrument panel. The vehicle
may still be driven for at least 80 km and, under ideal conditions (for example,
no load) further.
The faulty tyre should be replaced as soon as possible. The tyre rim should be
checked for damage at a specialised workshop and replaced as necessary.
We recommend you contact your Authorised Service Centre. If more than one
tyre is being used under emergency co nditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
When the loss in tyre pressure is displayed on the instrument panel, this
implies that at least one tyre is being driven in emergency conditions ⇒.
