Red symbols
A red symbol warns of a danger.–Stop the vehicle.
– Switch the engine off.
– Check the fault. Obtain professional assistance if necessary.
The red symbols are used to indicate a Priority 1 fault (serious malfunction).
A red symbol is accompanied by three warning chimes. The symbols will keep
flashing until the faults are corrected. If several Priority 1 faults are detected
at the same time, the symbols are displayed one after the other for about 2
seconds.Fault in the brake system
A fault in the brake system should be rectified as soon as
possible.If the symbol
flashes in the display, there is a fault in the brake
system. One of the following messages will appear in the display
together with the symbol:
Stop vehicle, check brake fluid and hydraulic fluid levels
Warning! Fault in brake system (ABS) Please visit garage
–Stop the vehicle.
– Check the brake fluid level ⇒page 237.
If the ABS fails, the ABS warning lamp
will light up together with the brake
system fault symbol
⇒ .
WARNING
•Before opening the bonnet and checking the brake fluid level, observe
the warning information in ⇒ page 227, “Work in the engine compart-
ment”.•If the brake fluid level in the reservoir is too low, this could result in an
accident. Do not drive on. Obtain technical assistance.

78•If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that the control function of the ABS is out of action. As
a result, the rear wheels can lock relatively easily when braking. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent dang er of skidding. Drive carefully to the
nearest specialist garage and have the fault rectified.
Fault in the cooling system
Faults in the cooling system must be rectified immediately.If the
symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
– Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒page 232.
– Add more coolant if necessary ⇒page 233.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. If the alternator warning lamp lights up as well
⇒page 69, it is possible that
the drive belt has broken.
Caution
Do not drive on if the symbol
has come on to indicate a fault in the cooling
system, otherwise there is a risk of engine damage.
Engine oil pressure too low
If the engine oil pressure is too low the fault must be rectified
immediately.If the
symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
– Stop the vehicle.
– Switch the engine off.
– Check the engine oil level ⇒page 230.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒page 230.
Engine oil level correct
If the
symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on. Do not continue to run the engine, even at
idle speed .

80Brake light failure
This warning light will appear on the upper part of the display if any of the
brake lights has failed. A text message in the central part of the display indi-
cates which brake light has failed (left or right).Fuel level low
When this symbol
comes on for the first time, there are about 8 to 10 litres
of fuel left in the tank. You should fill up as soon as possible ⇒page 222.
Check engine oil level
If the
symbol lights up, please check the engine oil level as soon as
possible ⇒page 230. Top up the oil at the next opportunity ⇒page 230.
Engine oil sensor defective*
If the
symbol lights up, take the vehicle to a qualified workshop and have
the oil level sensor checked. Until then it is advisable to check the oil level
every time you fill up with fuel ⇒page 230.
Diesel particulate filter obstructed
If the symbol
lights up, you may be able to contribute towards automatic
filter cleaning by driving in the right manner. To do this, drive about 15
minutes in 4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h, with the engine running at approximately 2000 rpm. The increase in
temperature will burn off any soot in the filter. When cleaning is successful,
the symbol switches off.
If the light on symbol
does not go off, take the vehicle to a specialist
garage to repair the fault.
For further information on the diesel particulate filter, see ⇒page 197.
WARNING
It is essential that you adjust your speed to suit the weather, road, terrain
and traffic conditions. The recommended driving speed must never lead to
the driver disregarding the traffic regulations.Light sensor/ rain sensor faulty
Automatic headlights / automatic wipers faulty
If the symbol appears, this means that the light sensor / rain sensor is not
working. For safety reasons, the dipped beam headlights will then be
switched on permanently when the light switch is set to the AUTO position.
However, you can still switch the lights on and off in the normal way with the
light switch. If the rain sensor is faulty, the functions operated via the wind-
screen wiper lever will still be available. You should have the light sensor /
rain sensor checked by a specialist garage as soon as possible.
Worn brake pads
If the
symbol lights up, have the front brake pads (and, for safety's sake,
the rear pads as well) inspected by a specialist garage.

Unlocking and locking
108If the indicators do not flash, check the doors, the bonnet and the tailgate to
ma ke su re t he y ar e pr op e rly close d . T h e in di cato rs will a lso flash br i ef ly i f o ne
of the doors or the tailgate or engine bonnet are closed after the alarm system
has been enabled.
LED
When the vehicle is locked, the LED on the top of the driver's door trim will
flash rapidly for about 30 seconds and then continue flashing slowly. This is
to indicate that the anti-theft alarm system (including the interior monitor
and tow-away protection ) is operative. If the LED lights up continuously for
about 30 seconds when the vehicle is locked instead of flashing, this means
the alarm system is not working properly.
Note
•To make sure that the alarm is fully operative when leaving the vehicle,
briefly check that all the doors and windows and the sun roof* are closed.•The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is enabled.
Interior monitoring*
The interior monitor triggers an alarm if it detects movement
inside the vehicle.You should disable the interior monitor if there is a possibility that
the alarm could be triggered, e.g. by a pet or by an object moving
about inside the car ⇒ . The tow-away protection feature, which
is integrated into the alarm system, should be disabled if the car is
being towed or transported (e.g. by rail or ship).
Disabling the interior monitor
– Open the door and pull out the switch (with the symbol
) to
one side of the storage compartment, in the driver's door
⇒ fig. 79 .
– Then lock the vehicle.

Trailer towing201
Safety First
Controls and equipment
Practical tips
Technical Data
Where possible, operate the trailer with the maximum permitted
draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit.
Tyre pressure
Check the tyre pressures on your car, and adjust for “full load” conditions
(refer to the sticker listing the tyre pressures on the door pillar). It may also be
necessary to adjust the tyre pressures on the trailer according to the recom-
mendations of the trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. The two exterior mirrors should be fitted on folding arms. Adjust the
mirrors to give sufficient rear vision.
Headlights
Before starting a journey, check the headlight beam settings with the trailer
hitched up. If necessary, alter the height of the headlight beams by means of
the headlight range control. See ⇒page 120.
Power supply
When you remove the ignition key, the power supply to the trailer is inter-
rupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a removable
ball joint coupling. This is stored in the spare wheel well in the luggage
compartment together with the necessary fitting instructions.
Note
If you frequently tow, we recommend you also have vehicle ser viced between
services.
Notes on towing
Towing a trailer involves additional attention by the driver.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 car and trailer is reduced with increasing speed. Therefore,
it is advisable not to drive at the maximum permissible speed in an unfavour-
able road, weather or wind conditions. This especially applies when driving
downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of swaying . Never try to stop the “snaking” by increasing speed.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then more severely. This will prevent brake
tapping by the trailer wheels when they lock. Select a low gear in due course
before going down a steep downhill. This enables you to use the engine
braking to slow down the vehicle.
Swaying and pitching can be reduced by stabiliser aids. We recommend
having stabiliser aids installed when towing trailers with a high trailer load.
They can be purchased and installed at a Dealer.
Reheating
When climbing long hills in hot weather with the engine running fast in low
gear, you should keep an eye on the coolant temperature gauge ⇒page 60.
Reduce speed immediately if the needle moves to the right end of the scale.
If the temperature warning light
in the instrument cluster should start
flashing, stop the car and let the engine cool down by running it at idling
speed for a few minutes.

Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•The performance of a vehicle using biodiesel maybe somewhat reduced.•Fuel consumption of a vehicle using biodiesel may be slightly higher.•RME fuel is resistant to the cold down to approx. -10°C.•At temperatures below -10°C, we recommend using winter diesel fuel.•Your vehicle is designed to be refuelled with up to a maximum of 7%
blended biodiesel, in accordance with the DIN 51628 standard.Caution
•RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.•If you refuel with biodiesel, please be sure that it conforms to the
DIN E 14.214 standard.•If you use biodiesel that does not meet the required standard, the fuel
filter could become clogged.Note
•In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.•The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend you that, when having run 300 or 400 km after a
fuel change, the fuel filter change must also be done. Also note the instruc-
tions in the Inspection and Maintenance plan.•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.
Therefore, 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 generally sold
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.

Checking and refilling levels
232freeze protection of temperatures down to approx. -40°C. However,the
concentration of anti-freeze must not exceed 60%, as the anti-freeze protec-
tion would then drop and the performance of the coolant system would suffer.
Vehicles for countries with cold climates (e.g. Sweden, Norway and Finland)
have factory-filled anti-freeze protection for temperatures down to -35°C. In
these countries, the concentration of anti-freeze should always be at least
50%.
Caution
•It is advisable to have the cooling system checked before the winter
season to make sure that the antifreeze concentration is adequate for the
conditions to be expected. This applies particularly if you intend to take the
car into a colder climate zone. If necessary, have the antifreeze concentration
increased to 50 - 60% as required.•Use only anti-freeze G12++ , an additive meeting the “TL-VW 774G” spec-
ification. Other anti-freezes may give considerably inferior corrosion protec-
tion. The damage caused by the use of these anti-freezes may lead to a loss
of liquid coolant, causing serious damage to the engine.•The anti-freeze G12++ can be mixed only with anti-freeze additives G11,
G12 and G12+.
Checking the liquid coolant level
The liquid coolant level can be checked at a glance.– Switch the ignition off.
– Check the coolant level on liquid coolant expansion tank ⇒fig. 181 . When the engine is cold, it should be between the
“min” and “max” marks. When the engine is hot, it may be
slightly above the “max” mark.Its location is shown in the corresponding general overview of the engine
compartment.
The liquid coolant level should be checked with the engine switched off.
The liquid coolant level is monitored by a warning lamp in the instrument
panel ⇒ page 78. However, we recommend that it should be checked occa-
sionally.

WARNING
when working in the engine compartment be aware that the radiator fan
may start running suddenly, leading to the risk of injury.Washer fluid and windscreen wiper bladesWindscreen washer system
Plain water on its own is not sufficient for the windscreen
washer system.The container for the windscreen washer contains the cleaning fluid for the
windscreen and the headlight washer system*. The container is located in the
engine compartment (front left). The fi ller cap is marked with the symbol
⇒ fig. 182 . The
capacity of the container is listed in ⇒page 295.
Plain water on its own is not enough to clean the glass properly. It is therefore
advisable to add a suitable washer fluid additive (with wax solvent) to the
water. A washer fluid with freeze-resistant additive should be used in winter.
Caution
•Never put radiator anti-freeze or other additives into the windscreen
washer fluid.•Never use washer fluid which contains paint thinners or solvents as it can
damage the paintwork.

WARNING
Do not drive unless you have good visibility through all windows!•Clean the windscreen wiper blades and all windows regularly.•The wiper blades should be changed once or twice a year.Caution
•A damaged or dirty window wiper could scratch the rear window.•Never use fuel, nail varnish remover, paint thinner or similar products to
clean the window.•Never move the windscreen wiper by hand. This could cause damage.
Brake fluidChecking the brake fluid level
The brake fluid level can be checked at a glance.The brake fluid level must be between the “Min” and “Max” ⇒fig. 187 mark-
ings.
The fluid level may drop slightly after a period of time due to the automatic
compensation for brake pad wear. This is quite normal.
H owe ve r, if th e le ve l goes d own not icea bly i n a short time, or drops below the
“Min” mark, there may be a leak in the brake system. If the fluid level in the
reservoir is too low, this will be indicated by the brake warning lamp
⇒ page 70 and ⇒page 77. If this should happen, take the car to a qualified
workshop immediately and have the brake system inspected.
