–
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 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.
CAUTION
If you run out of coolant in the expansion
tank, park the car in a saf
e place and do
not continue driving. Obtain technical as-
sistance.

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
light on the instrument panel display monitors
the brake fluid level

In right-hand drive vehicles the brake fluid
reservoir is on the other side of the engine
compartment.
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.
