eep pressing the refill bottle.


Refilling AdBlue® with a filler nozzle
The AdBlue® tank can be refilled at all AdBlue® pumps for passenger cars.
The filler nozzle may click off prematurely if filling is performed at a truck filling pump. There is a risk
of AdBlue® spilling out due to the much higher filling speed.

The handle of the filler nozzle must point down during refilling in order to guarantee optimum
filling.
Do not continue filling because the AdBlue® tank can be damaged by overfilling ⇒ .

The coolant additive is dyed purple. The mixture of water and a coolant additive offers anti-freeze
protection down to -25°C (-13°F), protects the alloy parts in the cooling system against corrosion,
prevents limescale deposits and significantly increases the boiling point of the coolant.
When refilling the coolant, a mixture of distilled water and at least 40% coolant additive - G 13 - or -
G 12 plus-plus - (TL-VW 774 G) (both of which are dyed purple) must be used in order to obtain the
optimum corrosion protection ⇒ .
Mixing - G 13 - with the coolant additives - G 12 plus - (TL-VW 774 F), - G 12 - (dyed red) or - G 11 -
(dyed blue-green) will significantly decrease the level of corrosion protection and should therefore
be avoided ⇒ .

WARNING
Insufficient anti-freeze in the coolant system can cause the engine to break down and cause serious
injuries.
ive used must be sufficient for the lowest
ambient temperature that you expect the vehicle to be exposed to.
Vehicle occupants with inadequate winter clothing could then freeze to death as the heating will
also no longer function.

NOTICE
Never mix genuine coolant additives with other coolants that have not been approved by
Volkswagen.
ts from mixing the purple
coolant additive with distilled water) but for example, brown instead of purple, - G 13 - has been
mixed with an unsuitable coolant additive. The coolant must be changed as soon as possible if this is
the case. Failure to observe this warning can result in serious malfunctions or damage to the engine
and cooling system.

Coolant and coolant additives can pollute the environment. Spilt service fluids must be collected and
then disposed of properly and in an environmentally responsible way.
Checking the coolant level and refilling coolant

Electromagnetic radiation
If a mobile phone or two-way radio is used without being connected to the external aerial, the
electromagnetic radiation will not be optimally directed to the outside of the vehicle. Increased
levels of radiation in the vehicle interior can occur in particular in the event of poor reception, e.g. in
rural areas. This can pose a health risk ⇒ .
With some equipment levels, a suitable mobile phone interface may be used to connect the mobile
telephone to the external aerial ⇒BookletInfotainment system,. The connection quality is improved
and the range is increased.
Using the telephone
Many countries require a hands-free system to be used when using a telephone inside the vehicle,
e.g. via a Bluetooth ® connection. Secure the mobile telephone to a suitable holder before using it ⇒
  or stow it securely away in one of the stowage compartments provided, e.g. in the centre
console.
Use a compatible mobile phone if the mobile phone interface uses SIM Access Profile (rSAP)
technology. If the LTE mobile standard is supported, use a SIM card with LTE data option.
Radio communication
Observe any legal requirements and the manufacturer's owner's manual when using radio
communication devices. Two-way radios must be approved if they are to be retrofitted in the
vehicle.
Contact your Volkswagen dealership for further information on installing a two-way radio.

WARNING
Mobile telephones which are loosely placed in the vehicle or not properly secured could be flung
through the interior and cause injuries during a sudden driving or braking manoeuvre, or in the
event of an accident.
them safely.

WARNING
If mobile telephones or two-way radios that are not connected to an external aerial are used,
electromagnetic radiation in the vehicle could exceed limit values and thus be a health hazard for
drivers and other vehicle occupants. This also applies to external aerials which have not been
correctly installed.
