WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
xAlways observe any lit warning lamps and text messages.
xNever ignore the warning lamps or text messages.
xStop the vehicle safely as soon as possible.
Caution
Failure to heed the warning lamps and text messages when they appear may

Engine coolant specifications
The engine cooling system comes with a special mixture of water and at least
40% G 12 plus-plus (TL-VW 774 G) or G 12 plus (TL-VW 774 F) engine coolant
additive. Both are easily recognisable because they are purple in colour.
This mixture gives the necessary frost protection down to -25 °C (-13 °F) and
protects the alloy parts of the cooling system against corrosion. It also
prevents scaling and raises the boiling point of the coolant.
To protect the engine cooling system, the proportion of additive must always
be at least 40%, even if frost protection is not required in countries with a
warm climate.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, decrease
the cooling capacity.
When adding coolant, a mixture of distilled water and at least 40 % of the
additive G 12 plus-plus must be use to ensure optimum rust protection Ÿ.

WARNING
In the event of insufficient antifreeze protection in the engine cooling
system, the engine could be damaged and severe injuries caused.
xEnsure that the proportion of engine coolant additive corresponds to
the lowest outside temperature to which the vehicle will be exposed.
xIf the outside temperature is extremely low, the engine coolant could
freeze causing the vehicle to stop. As this would also cause the heating to
stop working, passengers without sufficient clothing could freeze.
Caution
Never mix genuine additives with other additives that are not approved by
SEAT. Otherwise, you run the risk of causing severe damage to the engine and
the engine cooling system.
xThe engine coolant G 12 plus-plus can be mixed with G 12 plus and G 11.
xIf the fluid in the expansion reservoir is not purple but, for example,
brown, this means that you have mixed G 12 plus-plus or G 12 plus with
another coolant. The coolant must be changed as soon as possible if this is
the case! Failure to observe this point will result in serious malfunctions and
engine damage!
For the sake of the environment
Coolants and additives can contaminate the environment. Collect any spilt
fluids in suitable containers and dispose of in accordance with legislation
and with the utmost respect for the environment.
Checking the engine coolant level and refilling
If the coolant level is low, the coolant warning indicator will light.

Preparations
xPark the vehicle on even, flat and firm ground.
xAllow the engine to cool Ÿ.
xOpen the bonnet ’ Ÿpage 304.
xThe coolant expansion reservoir is easily recognisable because of the
symbol « on the cap Ÿpage 315, fig. 179.
Checking the engine coolant level
xWhen the engine is cold, check the coolant level using the side marking
on the expansion reservoir Ÿpage 315, fig. 178.
xIf the level is below the “MIN” mark, top up with coolant. When the engine
is hot it may be slightly above the marked area.
Topping up the engine coolant level
xAlways protect your face, hands and arms from hot coolant and steam
using a large, thick cloth over the coolant expansion tank cap.
xRemove the cap very carefully Ÿ.
xOnly refill using new engine coolant according to SEAT specifications
(Ÿpage 314) Ÿ.
xThe engine coolant level should be between the marks on the coolant
expansion tank Ÿpage 315, fig. 178. Do not exceed the top level of the
marked area Ÿ.
xScrew on the cap tightly.
xIf, the event of an emergency, you have no coolant that is compliant to the
required specifications (Ÿpage 314), never use another type of additive.
Instead, first top up with distilled water Ÿ only. Then re-establish the
correct proportion of the mixture with the correct additive as soon as possible
Ÿpage 314.
WARNING
Hot vapours and coolant can cause serious burns.
xNever open the coolant expansion tank if steam or coolant is coming
from the engine compartment. Wait until you cannot see or hear any steam
or coolant escaping.
xAlways wait until the engine has completely cooled before very care-
fully opening the expansion tank cap. Contact with hot elements of the
engine can cause skin burns.
xOnce the engine has cooled, follow the instructions below before
opening the bonnet:
Turn on the electronic parking brake and place the gear selector lever
in P or the gear stick in neutral.
Remove the key from the ignition.
Keep children away from the engine compartment and never leave
them unsupervised.
xWhen the engine is warm or hot, the cooling system is pressurised! Do
not unscrew the cap on the expansion tank when the engine is hot. Other-
wise, coolant may spray out under pressure causing burns and serious
injury.
Carefully and slowly unscrew the cap anticlockwise, gently pressing
down on it.
Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
xWhen refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire. Under specific
circumstances, the ethylene glycol can catch fire.
Caution
xTop up with distilled water only. Any other type of water may lead to
considerable rusting in the engine due to its chemical components. This
could consequently damage the engine. If you have not used distilled water

Disconnecting the vehicle's battery
If you must disconnect the battery from the electrical system, please note the
following:
xSwitch off the ignition and all electrical equipment.
xThe vehicle must be unlocked before disconnecting the battery, otherwise
the alarm will be triggered.
xFirst disconnect the negative cable and then the positive Ÿ.
Connecting the vehicle's battery
xBefore reconnecting the battery, switch off the engine, the ignition and
electric devices.
xFirst reconnect the positive cable and then the negative Ÿ.
Different control lamps may light up after connecting the battery and
switching the ignition on. They will be turned off after a short trip at a speed
of between 15 - 20 km/h (10 - 12 mph). If the warning indicators remain lit,
please visit a specialised workshop to have the vehicle checked.
If the battery has been disconnected for a long time, it is possible that the
next service date is not displayed or calculated correctly Ÿpage 64. Respect
the maximum service intervals permitted ŸBooklet “Maintenance
Programme”.

the ignition cannot be switched on, lock and unlock the vehicle from outside.
Then try to switch the ignition back on. If the ignition can still not be switched
on, request the assistance of a specialist workshop.
Automatic consumer disconnection
The intelligent vehicle electrical system automatically implements a range of
measures to prevent the battery from discharging when high demands are
made on it:
xthe idling speed is increased so that the alternator provides more elec-
tricity.
xwhere necessary, the power of the most powerful consumers is reduced
or even completely disconnected.
xOn starting the engine, the power supply from the 12-volt sockets and the
cigarette lighter may be interrupted for a short time.
The on-board management program cannot always prevent the battery from
running flat. For example, if the ignition is left on for a long period with the
engine off or if the side lights or parking lights are left on while the vehicle is
stationary.
Why does the battery run flat?
xWhen stationary for a long time without starting the engine, particularly if
the ignition is switched on.
xUse of electrical consumers with the engine switched off.
xIf the auxiliary heater is running Ÿpage 187.
WARNING
Incorrectly securing the battery or using the wrong battery can cause
short-circuits, fire and serious injuries.
xAlways use only maintenance free batteries that do not run flat alone
and whose properties, specifications and size correspond to the standard
battery. The specifications are indicated on the battery case.
WARNING
A highly explosive mixture of gases is released when the battery is under
charge.
xThe batteries should be charged in a well-ventilated room only.
xNever charge a frozen or recently thawed battery. A flat battery can
freeze at temperatures around 0°C (+32 °F).
