Checking and refilling levels
ment illustration ››› page 168. The brake fluid
id is too high, the brake system could cor-
rode. This also considerably reduces the boil-
ing point of the brake fluid. Heavy use of the
brakes may then cause a vapour lock which
could impair the braking effect.

When working in the engine compartment,
reservoir has a black and yellow cap.
always observe the safety warnings
››› page 166.
The brake fluid level drops slightly when the
vehicle is being used as the brake pads are
automatically adjusted as they wear.
●
When the engine is warm or hot, the cool-
ing system is pressurised! Do not unscrew
the cap on the coolant expansion tank when
the engine is hot. This is a burn injury risk.
Be sure to always use the correct brake fluid.
Only use brake fluid that expressly meets the
VW 501 14 standard.
However, if the level goes down noticeably in
a short time, or drops below the “MIN” mark,
there may be a leak in the brake system. A
display on the instrument panel will warn you
if the brake fluid level is too low ››› page 57.
CAUTION
You can buy VW 501 14 standard brake fluid
in a SEAT dealership or a SEAT Official Serv-
ice. If none is available, use only high-quality
brake fluid that meets DIN ISO 4925 CLASS 4
standards, or USA Standards FMVSS 116 DOT
4.
●
If you notice a change in the colour of the
liquid because it has been in use for a long
time, it is recommended to change it, as it
will have lost some of its properties and
could cause damage to the engine.
WARNING
Before opening the bonnet to check the brake
fluid level, read and observe the warnings
››› page 166.
●
If a lot of coolant fluid has been lost, wait
Using any other kind of brake fluid or one
that is not of a high quality may affect opera-
tion of the brake system and reduce its effec-
tiveness. Never use a brake fluid if the con-
tainer does not state that it complies with VW
501 14, DIN ISO 4925 CLASS 4 standards, or
USA standards FMVSS 116 DOT 4.
for the engine to cool. This avoids damaging
the engine. Large coolant losses are an indi-
cation of leaks in the cooling system. See a
specialised workshop immediately and have
the cooling system checked. Otherwise, there
is a risk of engine damage.
Changing the brake fluid
The Maintenance Programme indicates brake
fluid change intervals.
We recommend that you have the brake fluid
changed by a Technical Service.
WARNING
Brake fluid
Brake fluid is poisonous. Old brake fluid im-
pairs the braking effect.
Before opening the bonnet, please read and
follow the warnings ››› in Safety instruc-
tions on working in the engine compartment
on page 166 in section “Safety notes for
working in the engine compartment”.
