Operations before driving
●
After refilling the tank, only switch on the igni-
tion.
●
Leave the ignition on for at least 30 seconds
for the system to detect the fluid load.
●
Make sure you wait for at least 30 seconds
before starting the engine!
WARNING
AdBlue® should only be stored in its origi-
nal container, which should be tightly closed
and kept in a safe place.
NOTICE
●
When refilling, the nozzle grip should be
aligned downward. Otherwise the nozzle will
not connect automatically.
●
Do not try to add any more additive after
the nozzle has stopped for the first time. The
AdBlue® tank could overflow and AdBlue®
could spill out.
●
Only use AdBlue® that complies with the
ISO 22241-1 standard. Only use original con-
tainers.
●
Never mix AdBlue® with water, fuel or addi-
tives. Any type of damage caused by such a
mixture will not be covered by the warranty.
●
Never pour AdBlue® into the fuel tank! This
could result in engine damage.
●
Do not carry the refill bottle inside the
vehicle. If there is a leak (due to tempera-
ture changes or damage to the bottle), the
AdBlue® may damage the vehicle's interior.
For the sake of the environment
Dispose of the refill bottle in an environment-
friendly manner.
Note
Suitable AdBlue® refill bottles can be pur-
chased from SEAT dealerships.
