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 .

WARNING
If the fluid level has dropped below the MIN mark,  do not drive on.
Risk of accident! Seek professional help.

Changing the brake fluid
Brake fluid absorbs moisture. Therefore, it gradually absorbs moisture from
the atmosphere. If the water content in the brake fluid is too high, the brake
system could corrode. The water content also reduces the boiling point of
the brake fluid.
The brake fluid must comply with one of the following standards or specifi-
cations:
● VW 50114
● FMVSS 116 DOT4
WARNING
Heavy use of the brakes may cause a vapour lock if the brake fluid is left
in the brake system for too long. This would seriously affect the efficien-
cy of the brakes and the safety of the vehicle.
CAUTION
Brake fluid damages the vehicle paintwork. Windscreen washer
Fig. 128 Engine com-
partment: Windscreen
washer container
The container for the windscreen washer contains the cleaning fluid for the
windscreen or rear window and the headlight washer system. The container
is located in the engine compartment.
The container capacity is approx. 3.5 litres and, in vehicles with windscreen
washer system, approx. 5.4 litres 1)
.
Plain water on its own is not enough to clean the glass and the headlights
properly. We therefore recommend using clean water with a glass cleaning
product to eliminate any stubborn dirt (with an anti-freeze additive in win-
ter).
Although your vehicle has heated windscreen washer jets, anti-freeze
should always be added to the water in winter.
Ethanol can be used where glass cleaner with anti-freeze is unavailable. The
concentration of ethanol must be no greater than 15 %. However, remember
that anti-freeze in this proportion only protects down to -5 °C (23 °F). 
1)
Valid only for certain countries. 5.4 litres for both versions.

WARNING (Continued)
● The following is forbidden while working on the battery: fire and open
flames, smoking and activities that could produce sparks. Avoid causing
sparks when handling cables or electrical apparatus. Risk of injury in the
event of large sparks.
● Before working on the electrical system, you must switch off the en-
gine, the ignition and all electrical components and disconnect the cable
from the negative terminal (-) of the battery. To change a bulb, simply
switch off the corresponding light.
● Never charge a frozen or thawed out battery. Risk of explosion and
acid burns! Replace a frozen battery.
● Never use the jump leads on batteries in which the electrolyte level is
too low. Risk of explosion and acid burns.
● Never use a damaged battery. Risk of explosion! Replace a damaged
battery immediately.
CAUTION
● Never disconnect the battery when the ignition is switched on, as the
electrical system (electronic components) of the vehicle could be damaged.
When disconnecting the battery from the vehicle electrical system, discon-
nect its negative terminal (-) first. Only then may the positive terminal (+) be
disconnected.
● When connecting the battery, connect the positive terminal (+) first. On-
ly then may the negative terminal (-) be connected. The battery cables must
never be connected to the wrong battery terminals. Risk of burning the elec-
trical installation.
● Make sure the battery acid does not come into contact with the body-
work. Risk of paintwork damage.
● Do not expose the battery to direct sunlight to protect it from ultraviolet
radiation. ●
If the vehicle is not used for 3 or 4 weeks, the battery could run flat. This
is because some components use electricity even in standby mode (e.g.
control units). Prevent the battery from running flat by disconnecting its
negative terminal or leave it charging at a low current.
● If you frequently use the vehicle for short trips, the battery may not fully
charge and could run flat.
For the sake of the environment
A flat battery is particularly harmful waste for the environment. It must
therefore be disposed of according to current local law.
Note
Replace a battery once it is older than 5 years. 
Battery cover
Fig. 129 Battery: Open-
ing the cover
The battery is located beneath a plastic cover in the engine com-
partment.
– Open the battery cover in the direction indicated by the arrow
⇒ Fig. 129. 

193
Checking and refilling levels
– The positive terminal (+) of the battery is connected in reverse
order. 
Checking battery acid level
Fig. 130 Battery: Acid
level indicator
We recommend you have the acid level regularly checked at an official tech-
nical service, particularly in the following cases.
● At high outside temperatures.
● On long daily trips.
● Whenever the vehicle is loaded ⇒ page 193, Charging the battery.
In vehicles equipped with a battery with colour indicator, the so-called mag-
ic eye ⇒ Fig. 130 changes colour to indicate the acid level.
Air bubbles can influence the colour of the indicator. Therefore, carefully
knock the indicator before checking the acid level.
● Black – the acid level is correct.
● Colourless or light yellow – acid level too low, battery must be changed.
Note
● The battery acid level is also regularly checked during servicing at au-
thorised SEAT dealers.
● The acid level on “AGM” vehicle batteries cannot be checked for techni-
cal reasons.
● Vehicles equipped with the “START-STOP” system include a battery con-
trol unit to control the battery level for repeat engine starting. 
Winter service
At low temperatures the battery provides only a fraction of the starting pow-
er it has at normal temperatures.
A flat battery can also freeze at temperatures slightly below 0 °C (32 °F).
We therefore recommend you have the battery checked and, if necessary,
charged at an official SEAT technical service before the start of winter. 
Charging the battery
A fully-charged battery is essential for reliable starting.
– Switch off the ignition and all electrical equipment.
– For “fast-charging” only: disconnect both battery connection ca-
bles (first the “negative” terminal and then the “positive”).
– Connect the charger cables to the battery terminals (red = “pos-
itive”, black = “negative”).
– Plug in the battery charger and switch on. 

194Checking and refilling levels
–After charging the battery: Switch off the battery charger and
disconnect the cable.
– Remove the charger cables.
– If necessary, reconnect both battery cables to the battery (first
the “positive” cable, then the “negative” cable).
When charging with a low current (e.g. with a small battery charger), the
battery does not have to be disconnected. The instructions of the battery
charger manufacturer must be followed.
Use a current equivalent to or lower than 10% of the battery capacity to fully
charge the battery.
Before “fast-charging” the battery however, both battery cables must be
disconnected.
“Fast-charging” a battery is dangerous and requires a battery charger and
special knowledge. Fast charges should be performed by an official techni-
cal service.
The battery caps should not be opened while the battery is being charged.
CAUTION
In vehicles fitted with the “START-STOP” system, the charger cable cannot
be directly connected to the negative terminal of the vehicle battery but
must be attached to the engine earthing point ⇒ page 216. 
Disconnecting and connecting the battery
The following functions will either be inoperative or will not work properly
after disconnecting and reconnecting the battery:
effectInstallationSetting the clock⇒ page 60The multifunction display data is deleted⇒ page 61
Note
We recommend having the vehicle checked by an authorised SEAT dealer to
guarantee the correct working order of all electrical systems. 
Changing the battery
A replacement battery must have the same capacity, voltage, current rating
and size as the original. The appropriate types of battery can be acquired
from authorised SEAT dealers.
We recommend having the battery changed by an authorised SEAT dealer,
where the new battery will be correctly installed and the original disposed
of in line with regulations. 
Automatic disconnection of electrical equipment
When heavily-charging a battery, the programme selected by the electrical
system control unit prevents the battery from automatically discharging.
This may result in the following:
● Increase in idling speed so that the alternator can supply more current
to the electrical system.
● The performance of certain electrical components could be limited or
some may switch off temporarily, e.g. the heated seats, the heated rear win-
dow, the 12V power socket. 

Note
Despite any measures taken by the control unit, the battery could drain. e.g.
with the engine is switched off, the key is turned in the ignition for a long
period or the side lights or parking lights are switched on. The switching off
of certain electrical components does not impair driving comfort and the
driver will often not even realise. 
