WARNING
After refueling with a mixture of E85 and gasoline,
drive for at least 5 minutes so that the engine
management is optimally prepared for the current
mixture. During this time, oscillations in the engine
idle speed may occur. For this reason, during this
journey, avoid driving at high speed, high engine
speeds and full throttle.
The exhaust system components become
extremely hot and this can cause a fire.
· Park the vehicle so that no exhaust system
component comes into contact with easily
flammable materials that may be found under the
vehicle, such as dry grass.

If the fuel tank is overfilled, the fuel could splash

Warning and indication system in case of failure
Using the vehicle without the AdBlue® prescribed by
Volkswagen may be punishable.
If the exhaust gas purification system has a fault or has
been filled with AdBlue® that does not comply with the
ISO-22241-1 standard, the white or yellow control lamps
light up. When the yellow control lights come on,1a00r0ankgme of

Information regarding AdBlue®
If the yellow control lamps are ignored, the red warning
lamps light up. That gives a range of 0 km and it is not
possible to start the engine again.
The AdBlue® consumption depends on the driving style,
the operating temperature and the ambient temperature.
On the instrument panel screen you can check the
remaining range and the amount to be charged ÿ p. twenty.
ATTENTION
AdBlue® is an irritant and corrosive liquid that can cause
damage to the skin, eyes and respiratory organs if it
comes into contact with them.
Since AdBlue® freezes from -11 °C (+13 °F), if the
temperature is very low, there may be limitations when
refueling. The system is heated while driving to ensure
exhaust gas purification even at very low temperatures.
· Before using AdBlue® ,
observe the instructions for
use. If you follow the instructions for use correctly, it
is unlikely that you will come into contact with AdBlue® .
AdBlue® must be charged regardless of whether the
services are performed, as it may be required more frequently
or between service intervals.
· Store AdBlue® only in the tightly closed original
container. Never use empty food cans, bottles or other
containers.
Never allow the AdBlue® tank to empty completely ÿ p. 311.
· Always store AdBlue® in a safe place,
out of the reach of children.
