WARNING
If the vehicle has to be stopped for technical reasons, park it a safe dis-
tance away from moving traffic, switch off the engine and turn on the
hazard warning lights ⇒ page 101.

Coolant level and temperature 
If the warning lamp  (blue) is lit up, the engine has not yet reached its op-
erating temperature 1)
. Avoid high engine speeds, hard acceleration and
submitting the engine to high loads.
If the warning lamp  (red) is lit up or flashing, the coolant temperature is
too high or its level is too low.
The informative display indicates:
Check coolant! Instruction Manual!
Stop the vehicle, switch off the engine, check the coolant level ⇒ page 188
and refill if necessary ⇒ page 188.
If the coolant is situated in the prescribed area, the high temperature may
be due to a fault in the cooling system fan. Check the radiator fan fuse and
replace it if necessary ⇒ page 221, Changing fuses in the engine compart-
ment.
If the warning lamp  (red) remains lit up, despite both the coolant level
and the radiator fan fuse being in correct condition,  stop the vehicle!
Seek professional help.
WARNING
● If the vehicle has to be stopped for technical reasons, park it a safe
distance away from moving traffic, switch off the engine and turn on the
hazard warning lights ⇒ page 101.
● Take care when opening the coolant reservoir. When the engine is
warm or hot, the system is pressurised – Danger of burns! Wait for the
engine to cool before opening the cover.
● Do not touch the fan. The fan can switch on automatically regardless
of whether the ignition is switched on.

Power steering 
If the warning lamp,  is lit up there is a fault in the power steering.
The power steering system functions with reduced power steering effect.
Seek professional help. 
Stability Control (ESC) 
If the control lamp  flashes, the ESC is working.
If the warning lamp  lights up on ignition the ESC system may have
switched off due to technical reasons. Turn off the ignition and turn it on
again. Upon switching on the ignition again, if the warning lamp has switch-
ed off, this means the ESC is functioning correctly again.
If the warning lamp,  is lit up there is a fault in the ESC. 

CAUTION
● Anti-freeze that does not correspond to the correct specification may
particularly affect corrosion protection considerably.
● Faults caused by corrosion may lead to coolant leaks. Risk of serious en-
gine faults! 
Checking coolant level
Fig. 126 Engine com-
partment: Coolant tank
The coolant expansion tank is located in the engine compartment
of the vehicle.
– Switch the ignition off.
– Open the bonnet ⇒ page 182.
– Read off the coolant level on coolant expansion tank ⇒ 
Fig. 126.
When the engine is cold, the coolant should be between marks B
(min.) and
A (max.). When the engine is hot, it may be
slightly above mark A (max.).
If the brake fluid level in the reservoir is too low, this will be indicated by the
warning lamp  (red) in the general instrument panel ⇒ page 72, Coolant
level and temperature . However, we recommend checking the coolant
level directly in the tank.
Coolant fluid loss
Any loss of coolant normally indicates a leak. It is not sufficient merely to
top up the coolant. The cooling system should be inspected by an Official
Service without delay.
CAUTION
In the event of a fault that causes the engine to overheat, contact an author-
ised SEAT dealer immediately, as this could damage the engine. 
Topping up coolant
– Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion tank ⇒ Fig. 126 with a
cloth and carefully unscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into place.
Do not use a different type of additive if the prescribed anti-freeze additive
is not available, in the event of an emergency. In this case, use only water
and bring the coolant concentration back up to the correct level as soon as
possible at an Official Service. 

189
Checking and refilling levels
Always top up with unused coolant.
Never fill the coolant tank above mark A
(max.) ⇒ Fig. 126 Excess coolant
is forced out of the cooling system through the overpressure valve in the fill-
er cap of the expansion tank when the engine heats up.
WARNING
● The anti-freeze additive and, therefore, the entire coolant, are a
health hazard. Avoid touching the coolant. Coolant fumes are also a
health hazard. Store the coolant additive in a safe place out of the reach
of children. Risk of poisoning!
● If splashed into eyes, rinse immediately with clean water and seek
immediate medical advice.
● Seek immediate medical advice if the coolant is accidentally inges-
ted.
CAUTION
If the engine oil cannot be topped up under the given conditions,  do not
drive on. We recommend contacting an authorised SEAT dealer, as this can
damage the engine. 
Radiator fan
The radiator is driven by an electric motor and controlled according to the
temperature of the coolant.
After the engine has been stopped and the ignition switched off, the radia-
tor fan may continue running for around 10 minutes. Brake fluid
Checking brake fluid level
Fig. 127 Engine com-
partment: Brake fluid res-
ervoir
The brake fluid reservoir is located in the engine compartment of
the vehicle.
– Switch the ignition off.
– Open the bonnet ⇒ page 182.
– Check the brake fluid level in the reservoir ⇒ Fig. 127. It should
be between the “MIN” and “MAX” marks.
The fluid level drops slightly after a period of time due to automatic com-
pensation for brake pad wear. This is quite normal.
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. If the brake fluid
level in the reservoir is too low, this will be indicated by the warning lamp in
the instrument panel 
⇒  page 70, Brake system .

Checking fluid levels
From time to time, the levels of the different fluids in the ve-
hicle must be checked. Never fill with incorrect fluids, other-
wise serious damage to the engine may be caused.
