Diesel enginesTop-up quantity (in litres)1.6 l/77 kW TDI CR6.5
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. 

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 and refilling levels
CAUTION
● Never mix the windscreen washing water with anti-freeze used for the
cooling system or other additives.
● If the vehicle is equipped with a headlight washer system, only mix a de-
tergent that does not damage polycarbonates with the water.
Note
On topping up the fluid, do not move the filter on the container opening, as
this could contaminate the fluid pipes and, therefore, lead to a windscreen
washer malfunction. 
Battery Introduction
Warning symbols on the battery
SymbolMeaning
Always wear safety glasses!
Battery acid is extremely corrosive. Always wear gloves and
hearing protection!
Keep open flames, sparks, uncovered lights and lit cigarettes
away when working on the battery!
A highly explosive mixture of gases is released when the bat-
tery is under charge!
Keep children away from the battery!
Incorrect handling of the vehicle battery could lead to damage. We therefore
recommend all work on the vehicle battery be performed by an authorised
SEAT dealer.
Always be aware of the danger of injury and scalding as well as the risk of
accident or fire when working on the battery and the electrical system.
Therefore, always observe the warnings and follow all general safety pre-
cautions.
WARNING
● Battery acid is very corrosive, therefore, the battery must be handled
with the utmost care. Wear protective gloves and protect your eyes and
skin when handling batteries. The corrosive fumes in the air irritate and
inflame the respiratory tract and cause conjunctivitis. It corrodes tooth
enamel and causes deep, difficult-to-heal wounds when in contact with
the skin. Repeated contact with diluted acids causes skin disease (in-
flammation, ulcers and fissures). When in contact with water, acids dilute
and develop a great deal of heat.
● Do not tilt the battery, as acid could leak out of the vapour vents. Pro-
tect your eyes with glasses or a protective helmet! Risk of blindness! If
acid should splash into the eyes, rinse the affected eye immediately for
several minutes using clean water. Then seek medical care immediately.
● Neutralize any acid splashes on the skin or clothing with soap solu-
tion as quickly as possible and rinse off with plenty of water. If acid is
swallowed by mistake, consult a doctor immediately.
● Keep children away from the battery.
● Hydrogen is released and a highly explosive mixture of gases is gen-
erated when the battery is under charge. Sparks when disconnecting or
releasing cable terminals with the ignition switched on could also cause
an explosion.
● A short circuit is produced if the battery terminals are bridged, e.g.
using metal objects, cables, etc. Possible consequences of a short cir-
cuit: melting of lead plates, battery explosion and fire, splashing acid. 
