Coolant fluid loss
Any loss of coolant fluid normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a specialised work-
shop without delay. It is not sufficient merely to top up the coolant fluid.
If there are no leaks in the system, a loss of coolant fluid can only occur if
the coolant boils and is forced out of the system as a result of overheating.
CAUTION
Radiator sealants must not be added to the coolant fluid. Such additives
could seriously impair the function of the cooling system. 
Topping up the coolant fluid
Be careful when topping up with coolant fluid. – Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒ Fig. 182 with a cloth,
and carefully unscrew the cap anticlockwise ⇒ 
.
– Add coolant fluid.
– Screw on the cap tightly.
Make sure that the coolant fluid meets the required specifications
⇒  page 238. Do not use a different type of antifreeze if G12++antifreeze is
not available. In this case, use only water and bring the antifreeze concen-
tration back up to the correct level as soon as possible.
Always top up with new coolant fluid. Do not fill above the “max” mark. Excess coolant fluid is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of coolant fluid has been lost, wait for the engine to
cool down before
putting in cold coolant. Failure to do so could result in serious engine dam-
age.
WARNING
● The cooling system is under pressure. Do not unscrew the cap on the
expansion tank when the engine is hot. Failure to comply could result in
burns.
● The antifreeze and coolant fluid can be a health hazard. Therefore,
the antifreeze should be stored in the original container in a safe place
out of reach of children. Failure to comply could result in poisoning.
For the sake of the environment
Drained off coolant should not be used again. Drain off the used coolant in-
to a suitable container and dispose of it in the proper manner (observe envi-
ronmental regulations). 
Radiator fan
The radiator fan can start running spontaneously. The auxiliary fan can continue to run for as long as 10 minutes after stop-
ping the engine, even after the ignition is switched off. It may also start run-
ning suddenly ⇒ 
after some while if
● Stored heat raises the coolant temperature, or
● The hot engine compartment is additionally heated up by the sun. 

Washer fluid and windscreen wiper blades Windscreen washer system
Plain water is not sufficient for the windscreen washer sys-
tem.
Fig. 183 In the engine
compartment: Cap of
windscreen washer fluid
reservoir.
The container for the windscreen washer contains the cleaning fluid for the
windscreen and the headlight washer system*. The container is located in
the engine compartment (front left). The filler cap is marked with the symbol
 ⇒ Fig. 183. The capacity of the container is listed in ⇒ page 304. Plain water on its own is not enough to clean the glass properly. It is there-
fore advisable to add a suitable washer fluid additive (with wax solvent) to
the water. A washer fluid with freeze-resistant additive should be used in
winter.
CAUTION
● Never put radiator antifreeze or other additives into the windscreen
washer fluid.
● Never use washer fluid which contains paint thinners or solvents as it
can damage the paintwork. 

Removing the wiper blade
–Lift the wiper arm away from the glass ⇒ Fig. 186
– Slide the blade adapter in the direction of the arrow and remove
the blade ⇒ Fig. 186.
Fitting the wiper blade
– With one hand, hold the top end of the wiper arm.
– Place the blade as shown in the ⇒ Fig. 187 and slide the adapt-
er along until it engages.
Check the condition of the wiper blade regularly. Change as required.
If the windscreen wiper scrapes, it should be replaced if damaged, or
cleaned if soiled.
If this is not sufficient, refer to a specialised workshop.
WARNING
Do not drive unless you have good visibility through all windows!
● Clean the windscreen wiper blades and all windows regularly.
● The wiper blades should be changed once or twice a year.
CAUTION
● A damaged or dirty window wiper could scratch the rear window.
● Never use fuel, nail varnish remover, paint thinner or similar products to
clean the window.
● Never move the windscreen wiper by hand. This could cause damage. Brake fluid
Checking the brake fluid level
The brake fluid level can be checked visually.
Fig. 188 Engine com-
partment: markings on
brake fluid reservoir
The brake fluid level must be between the “Min” and “Max” ⇒ Fig. 188
markings.
The fluid level may drop slightly after a period of time due to the automatic
compensation 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 fluid level in
the reservoir is too low, this will be indicated by the brake warning lamp
⇒  page 73 and
⇒ page 80. If this should happen,
take the vehicle to a spe-
cialised workshop immediately and have the brake system inspected. 

Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will become
inoperative (e.g. electric windows). These functions will require resetting af-
ter the battery is reconnected. For this reason, the battery should only be
disconnected from the vehicle's electrical system when absolutely necessa-
ry.
Long periods of non-use
The battery will gradually lose its charge because certain electrical equip-
ment continues to draw current even when the ignition is off. If you park the
vehicle for long periods of time in winter you should take the battery out of
the vehicle and store it in a place protected from frost. This way it will not
freeze and become damaged. At warm outside temperatures it is sufficient
to disconnect the negative terminal of the battery. Even when the battery is
not connected you should charge it from time to time.
Winter operation
The battery is drained more in cold weather, which means that the starting
power is reduced. For this reason, have the battery checked and charged if
necessary before the start of winter.
Replacing the battery
A replacement battery must have the same capacity, voltage and current rat-
ing. It must also have the same dimensions as the original, factory-fitted
battery and have sealed caps. The SEAT batteries which have been specially
developed fulfil the maintenance, performance and safety specifications for
your vehicle.
We recommend you use maintenance-free batteries.
WARNING
● All work on batteries requires specialist knowledge. If work is re-
quired on the battery, this should be performed by a Technical Service or
specialised workshop. Danger of caustic burns and explosion!
● The battery must not be opened. Never try to change the battery's liq-
uid level. Explosive gas is released from the battery that could cause an
explosion.
CAUTION
● The battery holder and clamps must always be correctly secured.
● Before starting any work on the battery, always observe the warnings
listed under ⇒ 
.
For the sake of the environment
 Batteries contain toxic substances including sulphuric acid and lead.
Therefore, they must be disposed of in line with environmental regulations
and must not be disposed of with ordinary household waste. Make sure dis-
connected batteries cannot tip over. Sulphuric acid could be spilt! 
Important safety warnings for handling a vehicle battery
The battery is located at the back of the engine compartment ⇒ page 304.
Wear eye protection
Battery acid is very corrosive and caustic. Wear protective
gloves and eye protection!
Fires, sparks, open flames and smoking are prohibited! 

Wheels and tyres
Significant tyre pressure loss
The tyre symbol  is displayed and indicates that the tyre pressure
of at least one tyre is insufficient.
– Stop the vehicle.
– Switch the engine off.
– Check the tyre(s).
– Change the wheel if necessary. 
Tyre pressure monitoring (RKA+)*
The tyre pressure monitor display on the instrument panel
indicates if the pressure is too low.
Fig. 189 Detailed view of
the centre console: But-
ton for the tyre pressure
monitoring system The tyre pressure monitoring system makes use of the ABS sensors to com-
pare the rolling circumference and the frequency characteristics of the
wheels. If the rolling circumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp  will light up. The
fault will also be indicated by a warning buzzer. The position of the affected
tyre will also be shown (if only one tyre is affected) on the centre display of
the instrument panel.
The rolling circumference and frequency characteristics can change if:
●
the tyre pressure is too low.
● the tyre has suffered structural damage.
● the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).
● there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).
● the road surface under the left wheels is different to the road surface un-
der the right wheels for a long period.
● when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modifying
the tyre pressure ⇒ page 253 or after changing or swapping wheels
⇒ page 253 you should - with the vehicle at a standstill and the engine run- ning - press ⇒ Fig. 189. The yellow warning lamp  will light up. Hold the
button down for 2 seconds until the warning lamp goes out and an acoustic
warning is given. You can now release the button.
If the wheels are subjected to extreme stress (e.g. heavy load), the tyre
pressure must be increased to the recommended value for the maximum
load (see the adhesive label on the inside of the fuel tank flap) and then
initialise the system. 

Bulbs
General information
You can change the following bulbs for exterior lights yourself:
● Main headlights: all bulbs (except xenon headlights)
● Tail lights: all bulbs
● Side turn signal bulb
The following bulbs can only be changed by a specialised workshop:
● Main headlights: Xenon* bulb ⇒ page 279
● Front fog lights: Bulb
As a rule, you require a certain degree of practical skill to change defective
bulbs. This applies in particular to those bulbs which are only accessible
from the engine compartment.
If in doubt, we recommend that you have defective bulbs changed by a spe-
cialised workshop or qualified mechanic.
If you do decide to change bulbs in the engine compartment yourself, be
aware of the safety risks involved ⇒ page 234 ⇒ 
in Types of bulbs on
page 273. The name of many of the lamps fitted by SEAT ends in "LL". This means Long
Life. These lamps are used for functions with a long service time (dipped
beam, side lights, daylight driving, etc.). This does not apply to lamps with
a shorter service time (turn signals, etc.). A lamp with the same name ex-
cept for the last two letters, "LL“ or “SLL”, is compatible, but will have a
service life of approximately half of the LongLife lamps.
When replacing lamp bulbs, the same type of bulb as originally fitted
should always be used where possible.
