Practical tips
However, the heating power and the propor-
tion of nitr
ogen and carbon dio
xide can fluc-
t
uate within the quality groups. Therefore, ve-
hicle consumption can also vary when using
a single type of gas only.
The engine management automatically
adapts to the natural gas used according to
its quality. Therefore, different quality gases
can be mixed in the tank, without the need for
comprehensive draining before applying a
different quality gas.
Natural gas and safety

leak

Regular checks of the natural gas system
The natural gas tanks may be damaged or
corroded by external factors. The walls of the
gas tanks are weakened by deformations,
damage or corrosion. As a result, the tanks
could burst and result in serious injuries or
even death. For this reason, the vehicle owner
must have a specialised workshop check (vis-
ual check) the gas system every 4 years at
least. The vehicle owner must have a speci-
alised workshop replace the natural gas
tanks before they reach the end of their serv-
ice life. For further information about the serv-
ice life of gas tanks, go to a SEAT dealer serv-
ice or a specialised workshop
WARNING
Failure to act when you can smell gas in the
vehicle or when r
efuelling can cause seri-
ous injuries.
Carry out the necessary operations.
Leave the danger zone.
If necessary, warn the emergency serv-
ices.
WARNING
The vehicle is not suitable for liquefied nat-
ural gas (LNG) or liquefied petrol gas (LPG),
so LNG or LPG shoul
d not be used under
any circumstances. Liquid gas can cause
an explosion of the natural gas tanks and
cause severe injuries!
WARNING
Damaged, corroded or rusted tanks can re-
sult in serious injury or even death.
Hav
e the natural gas deposits checked at
least every 4 years (visual check).
Natural gas tanks have a limited service
life. Have the natural gas tanks replaced
when required. You can obtain further infor-
mation about this at SEAT dealers or speci-
alised workshops.
WARNING
If the vehicle underbody touches the
ground or in the ev
ent of a rear collision,
there could be damage to the natural gas
tanks.
Check whether there is a smell of gas.
If you notice a smell of gas, take the vehi-
cle to a specialised workshop immediately
and have the natural gas system checked.
Note
Have the natural gas system checked regu-
larly by a specialised workshop
, according
to the Maintenance Programme.
