232Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24 °C, provided you use winter-grade diesel which is
safe to -15 °C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24 °C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (thinners or similar products) with diesel fuel.Working in the engine compartmentSafety instructions on working in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear lever to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle. 6. Raise the bonnet
⇒page 234.
You should not do any work in the engine compartment unless you know
exactly how to carry out the jobs and have the correct tools! Have the work
carried out by a specialised workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs and
batteries, are being constantly developed. SEAT provides a constant flow of
information to the Authorised Service Centres concerning modifications. For
this reason, we recommend you to have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 224. The engine compartment of the vehicle is a
hazardous area. ⇒ .
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves a risk of injury and scalding as well as the risk of
accident or fire.•Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.•Switch off the engine and remove the key from the ignition.•Apply the handbrake and move the gear lever to neutral or selector
lever to position P.•Keep children away from the vehicle.•Never touch hot engine parts. There is a risk of burns.•Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.•Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 282. The battery could
explode.

•Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!•Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!•Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.•A l w ays ma ke s u re yo u ha v e n o t l e f t a n y obj e c ts , s u ch as c l ea n in g cl o t h s
and tools, in the engine compartment.•If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.•If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is applied.
Danger of death.•If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered. −
Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.
Caution
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to th e environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a specialised
workshop.

To change the blades it is necessary to change the rest position of
the wipers to the service position.
Service position (For changing wiper blades)
– Ensure that the wiper blades are not frozen.
– Turn ignition on and off and then (before approx. 8 seconds have
elapsed), move the windscreen wiper lever to the intermittent
wipe position. The windscreen wipers will move to the service
position.
Changing the windscreen wiper blades
– Lift the wiper arm away from the windscreen.
– Push the side buttons, free the blade and pull in the direction of the arrow ⇒fig. 168
Fitting the wiper blade
– Insert a blade of identical length and design into the wiper arm.
– Slide the blade until it clicks into position.
– Push the wiper arms back against the windscreen.If the windscreen wipers smear , t h e y s h o u l d b e r e p la ce d i f t h e y a r e d a m a ge d ,
or cleaned if they are soiled.
If this does not produce the desired results, the setting angle of the wind-
screen wiper arms might be incorrect. They should be checked by a special-
ised workshop and corrected if necessary.
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
•Damaged or dirty windscreen wipers could scratch the windscreen.•Never use fuel, nail varnish remover, paint thinner or similar products to

charge. Never short the battery terminals. High-energy sparks can cause
injury.
•A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.•Keep children away from acid and batteries.•Before working on the electrical system, you must switch off the
engine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only switch
off the light.•Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.•When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.•Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never
reverse the polarity of the connections. This could cause an electrical fire.•Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0 °C.•Ensure that the vent hose is always connected to the battery.•Never use a defective battery. This could cause an explosion. Replace a
damaged battery immediately.Caution
•Never disconnect the battery if the ignition is switched on or if the engine
is running. This could damage the electrical system or electronic compo-
nents.•Do not expose the battery to direct sunlight over a long period of time, as
the intense ultraviolet radiation can damage the battery housing.
•If the vehicle is left standing in cold conditions for a long period, protect
the battery from freezing. If it freezes it will be damaged.Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the engine bonnet and the battery cover ⇒ in “Safety
instructions on working in the engine compartment” on
page 232 ⇒ in “Warnings on handling the battery” on
page 246.
– Check the colour display in the "magic eye" on the top of the battery.
– If there are air bubbles in the window, tap the window gently until they disperse.The position of the battery is shown in the corresponding engine compart-
ment diagram ⇒page 291.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery.
There are two different colours:•Black: correct charge status.•Transparent/clear yellow: the battery must be replaced. Contact a
specialist workshop.

Bulb changeGeneral notesBefore changing any bulb, first turn off the failed component.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a
reduction in the bulb life and condensation on the mirror surface, thus
reducing efficiency.
A bulb should only be replaced by one of the same type. The type is inscribed
on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle.

26)On this type of headlight, the bulb changes must be made by the SEAT dealer, given
that complex elements must be removed from the vehicle and a reset must be made
on the automatic control system incorporated.27)The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5
times more than that of halogen bulbs, this means that, except due to unusual circum-
stances, there is no need to change the bulbs for the whole life of the vehicle.
