added safety risk from the rotating parts (e.g. drive belts, alternator, radi-
ator fan, etc.) and from the high-voltage ignition system.•Observe the following additional warnings if work on the fuel system or
the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near open flames.
− Always keep an approved fire extinguisher immediately available.Caution
When topping up fluids, make sure the correct fluid is put into the correct
filler opening. This can otherwise cause serious malfunctions or engine
damage.
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected at the workshop.
Note
On right-hand drive vehicles some of the reservoirs mentioned below are
located on the other side of the engine compartment.Closing the bonnet– To close the bonnet, push it down until it overcomes the spring
pressure.
– Let the bonnet engage in the locking part. Do not force it ⇒ .
WARNING
•For safety reasons the bonnet must always be completely closed when
the vehicle is moving. After closing it always check that it is properly
secured. The bonnet must be flush with the adjacent body panels.•Should you notice that the bonnet is not safely secured when the
vehicle is moving, stop the vehicle immediately and close the bonnet.
Failure to do so could result in an accident.
Engine oilGeneral notesThe 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.

Technical Specifications
As the use of good quality oil is necessary for the correct operation and long
service life of the engine, when it becomes necessary to replenish or change
the oil, always use an oil that complies to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; when the container displays the
specific standards for petrol and diesel engines together, it means that the
oil can be used for both types of engines.
We recommend that the oil change, indicated in the Maintenance
Programme, be performed by an Authorised Service Centre or a qualified
workshop.
The correct oil specifications for your engine are listed in
⇒page 231, “Oil
properties”.
Service intervals
Service intervals can be flexible (LongLife service) or fixed (dependent on
time/distance travelled).
If the PR code that appears on the back of the Maintenance Programme
booklet is QG1, this means that your vehicle has the LongLife service
programmed. If it has the codes QG0 or QG2 the interval service is dependent
on time/distance travelled.
Flexible service intervals (LongLife*)
Special oils and processes have been developed which, depending on the
characteristics and individual driving profiles, allow to extend the oil change
service (LongLife service intervals).
Because this oil is essential for extending the service intervals, it must only
be used observing the following indications:
•Avoid mixing it with oil for fixed service intervals.•Only in exceptional circumstances, if the engine oil level is too low
⇒ page 232 and LongLife oil is not available, it is permitted to top up (once)
with oil for fixed service intervals (up to a maximum of 0.5 litres). Fixed service intervals*
If your vehicle does not have the “LongLife service interval” or it has been
disabled (by request), you may use oils for
fixed service intervals, which also
appear in ⇒page 231, “Oil properties”. In this case, your vehicle must be
serviced after a fixed interval of 1 year / 15,000 km (whatever comes first)
⇒ Booklet “Maintenance Programme”.
•In exceptional circumstances, if the engine oil level is too low
⇒ page 232 and you cannot obtain the oil specified for your vehicle, you can
put in a small quantity of oil conforming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel engines) (up to 0.5l).
Vehicles with diesel particulate filter*
All Exeo vehicles with a diesel engine have a diesel particulate filter and must
only be filled with VW 507 00 engine oil, which has a low level of soot forma-
tion. Using other types of oil will cause a higher soot concentration and
reduce the life of the DPF. Therefore:•Avoid mixing this oil with other engine oils.•Only in exceptional circumstances, if the engine oil level is too low
⇒ page 232 and you cannot obtain the oil specified for your vehicle, can you
put in a small quantity of oil (once) conforming to the VW 506 00, VW 506 01,
VW 505 00, VW 505 01 or ACEA B3 / ACEA B4 specification. (up to 0.5 l).Oil propertiesEngine type

232Engine oil additives
No type of additive should be mixed with the engine oil. The deterioration
caused by these additives is not covered by the warranty.
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 oil level
Checking oil level
– Park the vehicle in a horizontal position.
– Briefly run the engine at idle speed until the service temperature
is reached and stop.
– Wait two minutes.
– Pull out the dipstick. Wipe the dipstick with a clean cloth and insert it again, pushing it in as far as it will go.
– Then pull it out once more and check the oil level ⇒page 232,
fig. 177 . If the oil level is too low, add more engine oil
⇒ page 233.

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 . 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.

Checking and refilling levels
234The 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- 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 be mixed only with antifreeze additives G11, G12
and G12+.Checking the coolant level
The coolant level can be checked visually.– Switch the ignition off.
– 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 occa-
sionally.
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 233, “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 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 into
a suitable container and dispose of it in the proper manner (observe environ-
mental regulations).

236Radiator 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.
Washer fluid and windscreen wiper bladesWindscreen washer system
Plain water 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
W
⇒ fig. 180.
The capacity of the container is listed in ⇒page 301.
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.

238Changing windscreen wiper blades
If the windscreen wiper blades are in perfect condition, you
will benefit from an improved visibility. Damaged wiper
blades should be replaced immediately.
Removing the wiper blade
– Lift the wiper arm away from the windscreen.
– Slide the retainer catch on the wiper blade in the direction indi-
cated ⇒fig. 181 . Hold onto the wiper blade at the same time.
– Pull the wiper blade out of its mounting on the wiper arm.
Fitting the wiper blade
– Slide back the retainer catch on the new wiper blade. The mounting on the wiper blade should now be visible.
– Fit the new wiper blade into the mounting on the wiper arm ⇒fig. 182 .
– Slide the retainer catch on the wi per blade in direction so that
it clicks into place on the wiper arm.
– Fold the wiper arm back down onto the glass.If the windscreen wipers smear , they should be replaced if they are
damaged, or cleaned if they are soiled.
If this does not produce the desired results, the setting angle of the wind-
screen wiper arms might be incorrect. They should be checked by a qualified
workshop and corrected if necessary.
WARNING
Do not drive unless you have good visibility through all windows!•The ignition must not be switched on while the front wiper arms are in
a raised position. The wipers would return to their park position and
damage the paintwork on the bonnet.
