reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture
of distilled water and, at least, 40 % of the G
13 or G 12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-

corrosion protection
. The mixture of G
13 with G 12 plus (TL-VW 774 F), G 12 (red) or
G 11 (green-blue) engine coolants will signifi-
cantly reduce the anticorrosion protection
and should, therefore be avoided
WARNING
If there is not enough anti-freeze in the cool-
ant system, the engine may fail leading to se-
rious damage.
●
Please make sure that the percentage of
additive is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
When the outside temperature is very low,
●
the coolant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold.
CAUTION
The original additives should never be mixed
with coolants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system.
Checking and refilling levels
If the fluid in the expansion tank is not pur-

ple but is, for example, brown, this indicates
that the G 13 additive has been mixed with
an inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage.
For the sake of the environment
Coolants and additives can contaminate the

environment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment.

If the level is below the "MIN" mark, top up
with coolant. When the engine is hot it may
be slightly above the marked area.
