Coolant temperature gaugeThe coolant temperature gauge ⇒ fig. 38 only works when the ignition is
switched on. In order to avoid engine damage, please read the following
notes for the different temperature ranges.
Cold temperature
If the needle is still on the left of the dial, this indicates that the engine has
not yet reached operating temperature. Avoid high revs and heavy accelera-
tion and do not make the engine work hard. Normal temperature
In normal operations, the needle will settle somewhere in the centre of the
dial once the engine has reached running temperature. The temperature may
also rise when the engine is working hard, especially at high outside temper-
atures. This is no cause for concern, provided the warning lamp
v does not
light up in the instrument panel.
Warning temperature
If the symbol
 flashes in the display, this means that either the coolant
temperature is too high or the coolant level is too low ⇒page 78.
WARNING
•Before opening the bonnet and checking the coolant level, observe the
warning information ⇒page 224.•Never open the bonnet when steam or coolant is being released from it.
This could lead to burns. Wait until you can no longer see or hear escaping
steam or coolant.Caution
Accessories in front of the air inlet reduce the cooling effect of the coolant. At
high outside temperatures and high e ngine loads, there is a risk of the
engine overheating.

Cockpit
78•If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that there is a fault in the ABS control function. 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 specialised workshop and have the fault repaired.
Fault in the cooling system

Faults in the cooling system must be repaired 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 229.
– Add more coolant if necessary ⇒page 229.
– 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
v has come on to indicate a fault in the cooling
system, otherwise there is a risk of engine damage.
Engine oil pressure too low
E
If the engine oil pressure is too low the fault must be repaired
immediately.If the
E
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 226.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒page 227.
Engine oil level correct
If the
E 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 .

Air conditioning
156Air conditioning2C-ClimatronicDescription
The air conditioner is designed to automatically keep the
passenger compartment at the temperature you find most
comfortable at all times of the year.Recommended settings:
– Set the temperature to 22°C (71°F).
–Press the button ⇒page 158, fig. 130 .The following setting quickly provides a comfortable temperature inside the
vehicle. We therefore recommend you do not modify the setting unless you
find this temperature uncomfortable or where circumstances require as such.
The air conditioner provides heating and ventilation and also cools and dehu-
midifies the air inside the vehicle.
The air conditioner is fully automatic and will constantly maintain the temper-
ature which has been set. To achieve this, the temperature of the air supplied
to the interior, the blower speed (volume of air delivery) and the air distribu-
tion are regulated automatically. The system also takes solar radiation into
account and, therefore, no subsequent manual readjustments are required.
Therefore, automatic mode ⇒ page 159 should be used for the comfort of all
the passengers in virtually all conditions throughout the year.
Please note the following points:
The humidity of the air is automatically reduced when the system cools the
interior of the vehicle. This helps to prevent condensation on the windows. If the humidity and temperature outside the vehicle are high,
condensation
can drip off the evaporator in the air cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak.
If the outside temperature is low, the blower normally only switches to a
higher speed once the coolant has warmed up sufficiently (this does not
apply to the defrost setting).
In order to achieve maximum engine power, the air conditioner compressor is
temporarily switched off when pulling away from standstill with full throttle.
The compressor also switches off if the coolant temperature is excessively
high to ensure adequate engine cooling under extreme loads.
Pollution filter
The pollution filter (a combined particulate filter and activated charcoal filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
element must be replaced at the intervals specified in the Service Plan.
If the vehicle is driven in areas with a high level of air pollution and the filter
is no longer fully effective, it may be necessary to change the filter element
more frequently.
Caution
•If you suspect that the air conditioner system is damaged, switch over to
ECON mode to prevent further damage and have the system checked by a
qualified workshop.•Repairs to the air conditioner require specialist knowledge and special
tools. For this reason, please contact a qualified workshop if the system is not
working properly.

Solar-powered blower/sunroof*
If the vehicle is parked in sufficiently strong sunlight, the
blower will operate in solar-powered mode when the ignition
is switched off.After the ignition is switched off, the blower is supplied with electrical power
from the sunroof. Please ensure that outlets 3 and 4 are open ⇒page 163,
fig. 132 to ensure the best possible ventilation.
The blower only works when the sunroof is closed or tilted open at the rear.
If the air recirculation mode is on when you switch off the engine, the air
conditioner will automatically switch to fresh air ventilation.Auxiliary heater*Diesel vehicles are fitted with an auxiliary heater
2) to raise the temperature of
the interior as quickly as possible. At outdoor temperatures below +5°C and
with the engine running, the auxiliary heater will switch on and off automati-
cally depending on the temperature of the coolant.
In order to save fuel, the auxiliary heater can be can be switched off by briefly
pressing the button on the air conditioner.
Seat heating*
The surface and backrest of the front seats can be electrically
heated.Turn thumbwheel or ⇒fig. 133 to switch on and adjust the
heating on the left or right front seats.The heating is switched off when the thumbwheel is set to 0. The temperature
settings range from 1 to 6.
Caution
To avoid damaging the heating elements of the seat heating, please do not
kneel on the seat or apply sharp pressure to a single point.

– Turn the ignition key to position without pressing the acceler-
ator.
– Release the ignition key as soon as the engine starts (the starter motor must not be allowed to run on with the engine).
Vehicles with a diesel engine:
– Use the foot brake.
– Manual gearbox: Push the clutch pedal all the way down.
– Move the gear lever into neutral (automatic gearbox: selector lever to P or N) ⇒.
– Turn the ignition key to position . The pre-heating indicator light
D comes on while the glow plugs are preheating.
– When the indicator light
D goes out, turn the ignition key to
position . Do not press the accelerator.
– Release the ignition key as soon as the engine starts (the starter motor must not be allowed to run on with the engine).
When starting a very cold engine, it may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If the engine fails to start straight away, stop after 10 seconds and try again
after about half a minute.
Glow plug system*
To assist starting at low temperatures, diesel engines are equipped with a
glow plug preheating system. The preheating time depends on the coolant
temperature and the outside temperature. Start the engine as soon as the
glow plug indicator light
D goes out. When the engine is warm or at outside temperatures above +8°C, the glow
plug indicator light will only come on for about one second. This means that
the engine can be started
immediately.
If the engine will not start...
•⇒ page 284•⇒page 287•⇒page 220, “Refuelling”WARNING
Never run the engine in confined spaces, as the exhaust gases are
poisonous.
Caution
Avoid high engine speeds, full throttle and extreme load conditions until the
engine has reached its normal operating temperature, otherwise this can
damage the engine.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle stationary.
Start immediately. This will help avoid unnecessary exhaust emissions.Stopping the engine– Turn the ignition key to position ⇒page 168, fig. 137 .

Driving
170•The brake servo and the power steering system work only when the
engine is running. You need more strength to steer and brake the vehicle
when the engine is switched off. Given that you will be unable to steer and
brake as usual, this could lead to a risk of accidents and injuries.Caution
If the engine has been running under high load for a long time, there is a risk
of heat building up in the engine compartment after the engine has been
switched off; this could cause engine damage. Therefore, you should let the
engine idle for approximately 2 minutes before you switch it off.
Note
After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched off. It may also start running again
after some time if the coolant temperature rises due to a build-up of heat
under the bonnet, or if the engine is already warm and the engine compart-
ment is heated up further by direct sunlight.
HandbrakeHandbrake
The handbrake should be applied firmly to prevent the
vehicle from accidentally rolling away.Applying the handbrake
– Pull the handbrake lever up all the way.
Releasing the handbrake
– Pull the lever up slightly and at the same time press in the release
button ⇒fig. 138 -arrow-.
– Keep the release button pressed and push the lever all the way down ⇒ .

Trailer towing199
Safety First
Operating Instructions
Practical Tips
Technical Specifications
Where possible, operate the trailer with the maximum permitted
drawbar
load on the ball joint of the towing bracket, but do not exceed the specified
limit.
Tyre pressure
Check the tyre pressures on your vehicle, 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 119.
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 the vehicle serviced
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 slow to allow for
the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. There-
fore, it is advisable not to drive at the maximum permissible speed in unfa-
vourable road, weather or wind condit ions. This especially applies when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of swaying . Never try to stabilise the trailer by accelerating.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then harder. 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 weight.
They can be purchased and installed at a Technical Service.
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 lamp
v in the instrument panel should start
flashing, stop the vehicle and let the engine cool down by running it at idling
speed for a few minutes.

Checking and refilling levels
228
Caution•The oil level must never be above area . This could damage the cata-
lytic converter or the engine. Contact a qualified workshop to drain the engine
oil if necessary.•No additives should be used with engine oil. Any damage caused by the
use of such additives would not be covered by the factory warranty.For the sake of the environment
•Oil must not be disposed of in the drain or on the ground.•Always observe legal requirements when disposing of empty oil
canisters.Cooling systemCoolant fluid
The purpose of the coolant fluid is to carry heat away from the
engine. The correct amount of antifreeze is decisive in
preventing the cooling system from freezing in winter.The vehicle’s engine cooling system is filled for life at the factory, so no
coolant needs to be changed. The coolant fluid consists of a mixture of water
and antifreeze G12++. This is a glycol-based antifreeze with anti-corrosion
additives.
Coolant fluid additive
The amount of antifreeze required depends on the temperatures to be
expected in the winter season. If the antifreeze concentration is too low the
coolant can freeze, resulting in failure of the cooling system and heater. The cooling system is filled at the factory with the correct amount of anti-
freeze for the country concerned.
In most cases, the mixture consists of 60% water and
40% antifreeze. This
mixture gives the required antifreeze protection at temperatures down to -
25°C and particularly protects the metal parts of the cooling system against
corrosion. It also prevents scaling and significantly raises the boiling point of
the coolant fluid.
Countries with warm climate
The coolant fluid concentration must not be reduced by adding plain water,
even in the summer or in warm climates. The concentration of the antifreeze
must always be at least 40%.
Countries with cold climate
If greater freeze protection is required in very cold climates, the proportion of
G12++ antifreeze can be increased. A concentration of 60% offers antifreeze
protection of temperatures down to approx. - 40°C. However, the concentra-
tion of antifreeze must not exceed 60% , as the antifreeze protection 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 antifreeze protection for temperatures down to -35°C. In
these countries, the concentration of antifreeze 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
vehicle into a colder climate zone. If necessary, have the antifreeze concen-
tration increased to 50 - 60% as required.•Use only G12++ antifreeze, an additive meeting the “TL-VW 774G” spec-
ification. Other antifreezes may give considerably inferior corrosion protec-

Checking and refilling levels
230Make sure that the coolant fluid meets the required specifications
⇒ page 228, “Coolant fluid”. Do not use a different type of antifreeze if
G12++ antifreeze is not available. In this case, use only water and bring the
antifreeze concentration back up to the correct level as soon as possible.
Always top up with new coolant fluid.
Do not fill above the “max” mark. Excess coolant fluid is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of coolant fluid has been lost, wait for the engine to cool down before
putting in cold coolant. Failure to do so could result in serious engine
damage.
WARNING
•The cooling system is under pressure. Do not unscrew the cap on the
expansion tank when the engine is hot. Failure to comply could result in
burns.•The antifreeze and coolant fluid can be a health hazard. Therefore, the
antifreeze should be stored in the orig inal container in a safe place out of
reach of children. Failure to comply could result in poisoning.For the sake of the environment
Drained off coolant should not be used again. Drain off the used coolant into
a suitable container and dispose of it in the proper manner (observe environ-
mental regulations).
Radiator fan
The radiator fan can start running spontaneously.The auxiliary fan can continue to run for as long as 10 minutes after stopping
the engine, even after the ignition is switched off. It may also start running
suddenly ⇒ after some while if•Stored heat raises the coolant temperature, or•The hot engine compartment is additionally heated up by the sun.WARNING
When working in the engine compartment be aware that the radiator fan
may start running suddenly, leading to the risk of injury.
