Brake Fluid; Check And Refill The Brake Fluid; Changing Brake Fluid; Checking The Brake Fluid Level - Seat Arona Owner's Manual

Cover the coolant expansion tank cap with
–
a cloth and carefully unscrew it to the left
›››
.
Top up the coolant only if there is still cool-
–
ant in the expansion tank, otherwise you
could damage the engine. If there is no
coolant in the expansion tank, do not con-
tinue driving. You should obtain professional
›››
assistance .
If there is still some coolant in the expansion
–
tank, top 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 pressure. Do
●
not unscrew the cap on the coolant expan-
sion tank when the engine 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.

Practical tips

tank, park the car in a safe place and do
not continue driving. Obtain technical as-
sistance.

Brake fluid

Checking the brake fluid level

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

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 brake 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
84.
