Coolant temperature gauge
Fig. 38 Engine coolant
temperature gauge
The 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 A
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 B
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 outside8
910
temperatures. This is no cause for concern, provided the warning lamp

does not light up in the instrument panel.
Warning temperature C
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 226.
● 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 es-
caping steam or coolant.
CAUTION
Accessories in front of the air inlet reduce the cooling effect of the coolant.
At high outside temperatures and high engine loads, there is a risk of the
engine overheating. 

WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 226, Work in the engine com-
partment.
● If the brake fluid level in the reservoir is too low, this could result in
an accident. Do not drive on! Obtain technical assistance.
● 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 cer-
tain circumstances, the rear of the vehicle could suddenly sway from side
to side, with the subsequent danger 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 231.
– Add more coolant if necessary ⇒ page 232.
– 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 malfunc-
tion 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 cool-
ing 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 re-
paired 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 229.

Air conditioning
Air conditioning 2C-Climatronic
Description
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 AUTO
⇒ fig. 141 button.
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 de-
humidifies the air inside the vehicle.
The air conditioner is fully automatic and will constantly maintain the tem-
perature which has been set. To achieve this, the temperature of the air sup-
plied to the interior, the blower speed (volume of air delivery) and the air
distribution are regulated automatically. The system also takes solar radia-
tion into account and, therefore, no subsequent manual readjustments are
required. Therefore, automatic mode ⇒ page 164 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 ap-
ply 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 throt-
tle.
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 fil-
ter) 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. 

Before opening the bonnet make sure that the windscreen wiper
arms are not lifted away from the glass. Otherwise the paint may
be damaged.
– Lift the bonnet slightly ⇒ 
.
– Press the release catch under the bonnet upwards ⇒ fig. 176.
This will release the arrester hook under the bonnet.
– Open the bonnet.
The bonnet is held in position by a gas-filled strut.
WARNING
Never open the bonnet if you see steam or drips of coolant being re-
leased from the engine compartment. Failure to comply could result in
burns. Wait until no steam or coolant can be seen before opening the
bonnet.
 Work in the engine compartment
Extra caution is necessary when working on components in
the engine compartment.
Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
WARNING
● Switch the engine off.
● Remove the ignition key.
● Apply the handbrake firmly.
● If your vehicle is equipped with a manual gearbox, place the gear lev-
er in neutral. If you are driving an automatic vehicle, place the selector
lever in position P.
● Wait for the engine to cool down.
● Children should not be allowed to approach the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.
● Never open the expansion tank when the engine is hot. The cooling
system is under pressure.
● Protect face, hands and arms from any hot steam or hot coolant fluid
released by covering the cap with a large, thick rag when opening the ex-
pansion tank. 

compartment: Engine oil
filler cap
– Unscrew cap  from oil filler opening ⇒ fig. 244.
– Carefully put in the specified grade of oil ⇒ page 228, adding
0.5 litres at a time.
– After two minutes, check the oil level once again ⇒ page 229.
– Where necessary, add more engine oil.
– Replace the oil filler cap carefully and push the dipstick all the
way in.
WARNING
● When refilling with oil, make sure no oil falls onto hot engine parts.
Failure to comply could result in fire.
● Wash your skin thoroughly if it comes into contact with engine oil.
CAUTION
● The oil level must never be above area a. This could damage the cata-
lytic converter or the engine. Contact a qualified workshop to drain the en-
gine 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 canis-
ters. 
Cooling system Coolant 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 wa-
ter and antifreeze G12++. This is a glycol-based antifreeze with anti-corro-
sion additives.
Coolant fluid additive
The amount of antifreeze required depends on the temperatures to be ex-
pected in the winter season. If the antifreeze concentration is too low the
coolant can freeze, resulting in failure of the cooling system and heater. 

231
Checking and refilling levels
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 boil-
ing 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 antifreeze G12++ can be increased. A concentration of 60% offers anti-
freeze protection of temperatures down to approx. -40 °C. However, the con-
centration 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 sea-
son to make sure that the antifreeze concentration is adequate for the con-
ditions to be expected. This applies particularly if you intend to take the ve-
hicle into a colder climate zone. If necessary, have the antifreeze concentra-
tion increased to 50 - 60% as required.
● Use only G12++ antifreeze, an additive meeting the “TL-VW 774G” speci-
fication. Other antifreezes may give considerably inferior corrosion protec-
tion. The damage caused by the use of these antifreezes may lead to a loss
of coolant fluid, causing serious damage to the engine.
● G12++ antifreeze can only be mixed with antifreeze additives G11, G12
and G12+. 
Checking the coolant level
The coolant level can be checked visually.

Safety FirstOperating InstructionsPractical TipsTechnical Specifications

232Checking and refilling levels
–Check the coolant level on coolant fluid expansion tank
⇒ fig. 179. 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 coolant level should be checked with the engine switched off.
The coolant level is monitored by a warning lamp on the instrument panel
display ⇒ page 78. However, we recommend that it should be checked oc-
casionally.
Coolant fluid loss
Any loss of coolant fluid normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a qualified workshop
without delay. It is not sufficient merely to top up the coolant fluid.
If there are no leaks in the system, a loss of coolant fluid can only occur if
the coolant boils and is forced out of the system as a result of overheating.
CAUTION
Radiator sealants must not be added to the coolant fluid. Such additives
could seriously impair the function of the cooling system. 
Topping up the coolant fluid
Be careful when topping up with coolant fluid. – Switch the engine off.
– Wait for the engine to cool down. –
Cover the cap on the expansion tank ⇒ fig. 179 with a cloth,
and carefully unscrew the cap anti-clockwise ⇒ 
.
– Add coolant fluid.
– Screw on the cap tightly.
Make sure that the coolant fluid meets the required specifications
⇒  page 230, 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 anti-
freeze 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 dam-
age.
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 original 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 in-
to a suitable container and dispose of it in the proper manner (observe envi-
ronmental regulations). 
