Intelligent technology
Note
If you wish to equip the vehicle with accessories such as a front spoiler or
wheel covers, it is important that the flow of air to the front wheels is not
obstructed, otherwise the brakes can overheat.
Brake servo
The brake servo assists the driver when braking
The brake servo increases the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
WARNING
Ensure the vehicle does not move while in neutral, when the engine is
stopped. Failure to do so could result in an accident.
Note
If the brake servo is not working, e.g. because the vehicle has to be towed
or because it is broken, you will have to press the brake pedal considerably
harder to make up for the lack of servo assistance.
Power steering
Power steering makes it easier to turn the steering wheel
when the engine is running. Power steering assists the driver by reducing the force needed to turn the
steering wheel. Power steering does not work if the engine is off. In this case the steering
wheel requires much more force to turn.
If the steering is held at its
turning limit when the vehicle is stationary, this
will place an excessive load on the power steering system. Turning the
steering wheel to its limit places a load on the system, which causes noise.
It will also reduce the idling speed of the engine.
CAUTION
When the engine is running, do not turn the steering wheel to its limit for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering.
Note
● If the power steering should fail at any time or the engine is switched off
(for instance when being towed), the vehicle can still be steered. However,
more effort will be required to turn the steering wheel.
● If the system is leaking or malfunctioning, please take the vehicle to a
specialised workshop as soon as possible.
● The power steering system requires a special hydraulic fluid. The fluid
reservoir is located at the front of the engine compartment on the left
⇒ page 290. The correct fluid level in the reservoir is important for the pow-
er steering to function properly. The hydraulic fluid level is checked at the
Inspection Service.
Servotronic*
The servotronic system electronically adjusts the power as-
sisted steering.
In vehicles equipped with servotronic power steering the degree of power
assistance ⇒ page 189 is adjusted
electronically according to road speed.

Driving and the environment
Driving and the environment
Running-in Running in a new engine
The engine needs to be run in over the first 1500 km.
Up to 1000 kilometres
– Do not drive at speeds of more than 2/3 the maximum speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 kilometres
– 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 friction 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, its life will be increased and its oil consump-
tion reduced. Braking capacity and braking distance
The braking capacity 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 Authorised Service Centre more frequently than recommen-
ded in the Service Plan.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). In this case
the brakes should be dried by pressing the brake pedal several times.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.
● New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also ap-
plies when the brake pads have to be changed further on.
● If brakes are wet or frozen, or if you are driving on roads which have
been salted, braking power may be lower than normal.

Checking and refilling levels
CAUTION
● Petrol with standard EN 228 may be mixed with small quantities of etha-
nol. However, bioethanol fuels available at commercial establishments with
reference E50 or E85, which contain a high percentage of ethanol, may not
be used, as they will damage the fuel system.
● Even one tankful of leaded fuel would permanently impair the efficiency
of the catalytic converter.
● High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.
For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.
Petrol additives
Petrol additives improve the quality of the petrol.
The quality of the petrol influences the performance, power and life of the
engine. For this reason, you should use good quality petrol containing addi-
tives. These additives will help to prevent corrosion, keep the fuel system
clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems oc-
cur, the required additives must be added during refuelling. Diesel
Diesel*
Diesel fuel must conform to DIN EN 590 (EN = “European Standard”). It
must have a cetane number (CN) of at least 51. The cetane number indi-
cates the ignition quality of the diesel fuel.
Notes on refuelling ⇒ page 217.
Biodiesel*
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel fuel by
the diesel manufacturer in accordance with standard EN 590 or DIN 51628
is authorised and will not cause damage to the engine or the fuel system.
● The diesel engine has been designed to be used exclusively with diesel
fuel conforming to standard EN 590. Never refuel or use petrol, kerosene,
fuel oil or any other type of fuel. If you accidentally fill up the vehicle with
the wrong type of fuel, do not start the engine. Seek assistance from speci-
alised personnel. The composition of these fuels may severely damage the
fuel system and the engine.

WARNING (Continued)
● If any tests have to be performed with the engine running, there is an
added safety risk from the rotating parts (e.g. drive belts, alternator, ra-
diator 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.
● When the external temperature and level of humidity are high or when
the engine stops, it is possible for water to drop from the air conditioning
system evaporator potentially forming a small puddle on the ground. This is
normal and does not indicate a leak.
Note
On right-hand drive vehicles some of the reservoirs mentioned below are lo-
cated 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 proper-
ly secured. The bonnet must be flush with the adjacent body panels.
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet. Fail-
ure to do so could result in an accident.
Engine oil General notes
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 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 ap-
pear 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.
223
Checking and refilling levels
We recommend that the oil change, indicated in the Maintenance Pro-
gramme, be performed by an Authorised Service Centre or a specialised
workshop.
The correct oil specifications for your engine are listed in ⇒ page 223, 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 pro-
grammed. 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 224 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 al-
so appear in ⇒ page 223, 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 224 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 0.5
l).
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
formation. 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 224 and you cannot obtain the oil specified for your vehicle, you
can use 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).

Engine 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

dipstick
Checking oil level
– Park the vehicle in a horizontal position.
– Briefly run the engine at idle speed until the service tempera-
ture 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 ⇒ fig. 166. If
the oil level is too low, add more engine oil ⇒ page 225.
Oil level in area a
–
Do not top up oil.
Oil level in area b
–
Oil can be topped up. After topping up the oil level should be in
area a.
Oil level in area c
–
Oil must be topped up. After topping up the oil level should be
in area a.
Depending on how you drive and the conditions in which the vehicle is
used, oil consumption can be up to 0.5 l/1000 km. Oil consumption is likely
to be higher for the first 5000 km. Therefore, the engine oil level must be
checked at regular intervals, preferably when filling the tank and before a
journey.

– Unscrew cap from oil filler opening ⇒ fig. 229.
– Carefully put in the specified grade of oil ⇒ page 223, adding
0.5 litres at a time.
– After two minutes, check the oil level once again ⇒ page 224.
– 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.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
226Checking 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
concentration of antifreeze must not exceed 60%, as the antifreeze protec-
tion would then drop and the performance of the coolant system would suf-
fer.
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.
