Practical tips
Unscr
e
w the cap sl
owly and carefully while
pressing downwards on the cap.
.
Only refill the coolant if the coolant expan-
sion t
ank still cont
ains cool
ant; otherwise
you could damage the drive system. If
there is no coolant in the expansion tank, do
not continue driving. You should obtain pro-
fessional assistance
.
If there is still some coolant in the expansion
t
ank
, t
op up to the upper mark.
Top up with coolant until the level becomes
stable.
Screw the cap back on correctly.
If there is a coolant leak, take the vehicle spe-
cialised workshop to have the cooling system
examined.
WARNING
The cooling system is under pressur
e. Do
not open the coolant expansion tank cap
when the drive system is hot: risk of burns!
Store the antifreeze in its original con-
tainer and keep it out of reach of children.
If working inside the engine compart-
ment, remember that, even when the igni-
tion is switched off, the radiator fan may
start up automatically, and therefore there
is a risk of injury.
CAUTION
If you run out of coolant in the expansion
tank, park the v
ehicle in a safe place and
do not continue driving. Obtain technical
assistance.
Brake fluid
Check and refill the brak
e fluid

The brake fluid reservoir is located in the en-
gine compartment.
Checking the br
ak
e fluid l
evel
The brake fluid level must be between the 
and  markings.
However, if the brake fluid level goes down
noticeably in a short time, or drops below the
 mark, there may be a leak in the brake
system. Seek specialist assistance. A warning
light on the instrument panel display monitors
the brake fluid level
page 65.
Changing brake fluid
We recommend that you have the brake fluid
changed by a Technical Service.
WARNING
If the brake fluid level is low or unsuita-
ble/old br
ake fluid is used, the brake sys-
tem may fail or braking power may be re-
duced.
Check the brake system and the brake
fluid level regularly!
When the brake fluid is used and brakes
are subjected to extreme braking forces,
bubbles of vapour form in the brake sys-
tem. These bubbles can significantly re-
duce braking power, notably increasing
braking distance, and could result in the to-
tal failure of the brake system.
Be sure to always use the correct brake
fluid. Only use brake fluid that expressly
meets the VW 501 14 standard.
You can buy VW 501 14 standard brake
fluid in a SEAT dealership or a SEAT Official
Service. If none is available, use only high-
quality brake fluid that meets DIN ISO 4925
