.... Avoid
driving at high speed
Avoid travelling at top speed. Fuel consumption,
exhaust emissions and noise Levels all increase
very rapidly at higher speeds. Driving at moder­
ate speeds will help to save fuel.
Do not let the engine idle for longer than
necessary
Engine idling periods are automatically reduced
on vehicles with start/stop system*. On vehicles
without start/stop system*, it is worthwhile
switching off the engine at Level crossings, for in­
stance, or at traffic lights with a Long red phase.
The fuel saved after only 30 -40 seconds is great­
er than the amount of fuel needed to restart the
engine.
The engine takes a very Long time to warm up
when it is running at idling speed. Mechanical
wear and pollutant emissions are also especially
high during this initial warm-up phase. It is
therefore best to drive off immediately after
starting the engine. Avoid running the engine at
high speed.
Regular ser vicing
Regular servicing can establish a basis for good
fuel economy before you start driving. A well­
serviced engine gives you the benefit of im­
proved fuel efficiency as well as maximum relia­
bility and an enhanced resale value.
A poorly maintained engine can consume up to
ten percent more fuel than necessary.
Check the oil level when filling the tank. Oil con­
su mption depends to a great extent on the en­
gine load and engine speed. It is quite normal
that the oil consumption of a new engine only
reaches its lowest level after a certain mileage.
This means that the oil consumption can only be
properly assessed after about 5,000 km. Depend­
ing on your personal driving style, oil consump­
tion can be up to 0.5 Ltr./1,000 km.
Avoid short trips
The engine and emission control system need to
reach their proper working temperature in order
to minimise fuel consumption and emissions . Driving
A cold engine uses disproportionately more fuel.
The engine only reaches its working temperature
after about four kilometres, when fuel consump­
tion will return to a normal level.
Check tyre pressures
Always make sure the tyres are inflated to the
correct tyre pressures to save fuel. If the tyre
pressures are just 0.5 bar too Low, this can in­
crease the fuel consumption by as much as 5 %.
Due to the greater rolling resistance, under-infla­
tion also increases tyre wear and impairs han­
dling.
The tyre pressures should always be checked
when the tyres are cold.
Do not use winter tyres all through the year; they
will increase fuel consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel
consumption, so it is worth checking the Luggage
compartment occasionally to make sure that no
unnecessary Loads are being transported.
Save electrical energy
The engine drives the alternator to generate elec­
tricity. This means that fuel consumption rises
when more power is required for electrical equip­
ment. Switch off electrical equipment when it is
not needed. Electrical equipment which uses a
Lot of electricity includes the blower (at a high
setting), the rear window heating and the seat
heating*.

and topping up fluids
Diesel can thicken at very low temperatures,
which can result in problems starting the engine
or prevent the engine from running smoothly. For
this reason, filling stations in some countries of­
fer winter-grade diesel fuel during the cold
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
CD CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if you fill up with the
wrong type of fuel, as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.
Filling the tank
Procedure for filling the tank

Press the tank flap -arrow- ¢ Fig. 204 to open
it. Your vehicle has a new self-sealing fuel tank
without a tank cap.
� Insert the filler nozzle into the fuel filler neck
as far as the stop ¢ Fig. 205 and ensure it is
properly engaged.
� Start refuelling. When the automatic filler noz­
zle is operated correctly it will switch itself off
as soon as the tank is "full". Do not try to put in
more fuel after the nozzle cuts out, as this will
fill the expansion chamber in the fuel tank.
� When the fuel filler pump switches itself off,
wait for 5 seconds before pulling out the filler
nozzle so that any remaining fuel can flow into
the tank opening.
� Close the tank flap. Make sure you hear it click
into place.
The correct fuel grade for your vehicle is given on
a sticker on the inside of the tank flap. Further
notes on fuel ¢page 217.
The tank capacity of your vehicle is given in the
Technical data section ¢ page 258.
& WARNING
Fuel is highly inflammable and can cause seri­
ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or a spare fuel canis­
ter with fuel, do not smoke and keep away
from naked flames -risk of explosion!
- If,
in exceptional circumstances, you have to
carry a spare fuel canister, please observe
the following warnings:
- Never fill fuel into the spare fuel canister
with the canister placed in or on top of the
vehicle. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite -risk of explosion! Always
place the canister on the ground to fill it.
- Insert the filler nozzle as far as possible
into the spare fuel canister.

Never spill fluids on a hot engine. These flu­
ids can cause a fire (e.g. radiator anti­
freeze).
- Take care not to cause short circuits in the
electrical system, especially when working
on the battery.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off-risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.
- Never remove the engine cover panel -risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive
belts, alternator and radiator fan, etc., and
from the high-voltage ignition system.
- Vehicles with automatic gearbox: Never
open the throttle inadvertently (for instance
by hand from the engine compartment) if a
gear is engaged while the vehicle is station­
ary with the engine running. The vehicle
could otherwise start moving immediately
and possibly cause an accident.
- 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 naked flames.
- Always keep an approved fire extinguisher
immediately available.
CD 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. Checking

Engine oil
Choosing the correct engine oil grade
The service interval display in the instrument
cluster of your vehicle will inform you when it is
time for an oil change. We recommend having
the oil changed by a qualified workshop.
If you have to top up the oil between oil changes,
use the grades of oil specified in the table in ac­
cordance with VW standards. You will need to
know whether
- the vehicle is being serviced based on the flexi­
ble or fixed oil change service (see Last service
record in Service Schedule).
- the vehicle has a petrol or diesel engine (see
sticker on inside of fuel tank flap).
- a diesel particulate filter is fitted on the vehicle
(see Delivery Inspection section of Service

up to 0.5 Ltr./1000 km. Oil consumption is Likely
to be higher for the first 5000 km. For this rea­
son the engine oil Level must be checked at regu­
lar intervals, preferably when filling the tank and
before a journey.

_& WARNING
- Ensure that no oil comes into contact with
hot engine components when topping up:
this could cause a fire.
- Wash your skin thoroughly if it comes into
contact with engine oil.
CD CAUTION
- The oil Level must never be above area 0, as
this may result in damage to the catalytic
converter or to the engine. Contact a qua Li-
224 fied
workshop to extract the engine oil if
necessary
- No additives should be used with engine oil.
Any damage caused by the use of such addi­
tives would not be covered by the factory
warranty.
@ For the sake of the environment
- Never pour oil down drains or into the
ground.
- Always observe statutory requirements
when disposing of empty oil canisters.
Cooling system
Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant Level is monitored via a warning Lamp
on the infotainment display ¢page 12. However,
we re com mend that it shou Ld be checked occa­
sionally.
If you do need to top up the coolant, use a mix­
ture of water and coolant additive. We recom­
mend mixing coolant additive with distilled wa­
ter .
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the fol­
lowing coolant additives. It is possible to mix
these additives.

The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too Low, the coolant
can freeze and cause engine damage.

make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­
ble. In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.
Topping up coolant

tank
Checking coolant level
.. Park
your vehicle on a level surface .
.. Switch off the ignition .
.. Read off the coolant level on the coolant expan­
sion tank ¢ page 222, Fig. 211. When the en­
gine is cold, the coolant level should be be­
tween the marks. When the engine is warm, it
may be slightly above the top mark. Checking
and topping up fluids
Topping up coolant
Impor tant: The coolant expansion tank must not
be empty ¢(D.
.. Wait for the engine to cool down.
.. Cover the cap on the expansion tank with a
cloth, and carefully unscrew the cap anti-clock­
wise ¢ .&_ .
.. Add coolant in the correct concentration
¢ page 224 up to the top mark.
.. You should make sure that the fluid level re-
mains stable. If necessary, add more coolant.
.. Screw the cap on again tightly.
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off-risk of injury!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling sys­
tem -risk of engine damage! In this case, do
NOT drive on. Obtain professional assistance .
