Preliminary steps
●
Park the vehicle on a rm, at surface.
●
Wait for the electric drive system to cool
down ›››
.
●
Open the front bonnet ››› in Working in
the front compartment on page299.
●
The motor coolant expansion tank can be
recognised by the symbol on the cap
›››Fig.186
Check the level
When the vehicle is delivered (new vehicles),
the coolant may be above the marked area.
This is normal. It is not necessary to suck the
coolant out.
●
When the electric drive system is cold, check
the coolant level using the side marking on the
expansion tank ›››Fig.185. The coolant level
should be between the marks.
●
If the level is below the minimum level mark
( ) on the tank, top up with coolant. When
the engine is warm, the coolant level may be
slightly above the upper mark.
Topping up the uid
When the motor coolant level is too low, the
coolant warning light comes on. In this case,
immediately seek assistance from specialist
personnel.
If the coolant level is too low and there is no
workshop nearby, note the following:
●
Always protect your face, hands and arms
from hot coolant or steam by placing a suita-
ble cloth over the cap of the motor coolant
expansion tank.
●
Carefully unscrew the cap ››› .
●
Only top up with fresh coolant according to
CUPRA specications ›››page303.
●
Only top up with coolant if there is still some
coolant left in the expansion tank; otherwise
the drive system could be damaged! If you do
not see any coolant in the expansion tank, do
not continue driving and seek specialist assis-
tance.
●
If there is still some coolant left in the ex-
pansion tank, top up with coolant up to the
tank’s upper mark and check the level the next
day. If the level drops again, go to a workshop
and request a check of the cooling system.
●
The coolant level must be between the
marks on the expansion tank ›››Fig.185.
Never exceed the top edge of the marked
area ›››
.
●
Screw the cap on tightly.
●
If engine coolant with the recommended
specications is not available in an emergency,
do not use any other coolant additive! In this
case, top up with distilled water ››› only.
Next, ensure that the recommended additive
is topped up as soon as possible in the correct
proportion ›››page303.
WARNING
Steam and hot engine coolant can cause se-
vere burns.
●
Never open the front bonnet if you see
or hear steam or coolant escaping from the
front compartment. Always wait until you can
no longer see or hear steam or coolant es-
caping. Touching hot parts can result in skin
burns.
