Cleaning and caring for your vehicle
178Care of the vehicle exteriorAutomatic car washesThe paint is so durable that the car can normally be washed without problems
in an automatic car wash. However, the effect on the paint depends to a large
extent on the design of the car wash, the brushes used, the filtering of the
wash water and the type of detergents and wax solutions used, etc.
After the car has been washed, the brakes could respond later than normal
as the brake discs and brake pads will be wet, or even frozen in winter. You
must “dry” the brakes by applying the brakes carefully several times
⇒ page 169, “Braking effect and braking distance”.
WARNING
Moisture, ice and salt on the brakes may affect braking efficiency. Risk of
accident.Washing by handWashing the vehicle
– First soften the dirt with plenty of water and rinse off.
– Clean the vehicle with a soft sponge, a glove or a brush. Start on
the roof and work your way down. Use only light pressure.
– Rinse the sponge or glove as much as possible.
– Special car shampoo should only be used for very stubborn dirt. – Clean the wheels, sill panels etc. last using a different sponge or
glove.
– Rinse the vehicle thoroughly with water.
– Dry the surface of the vehicle gently using a chamois leather.
–If it is cold , dry the rubber seals and the surfaces they touch with
a cloth to prevent them freezing. Apply silicone spray to the
rubber seals.
After cleaning the vehicle
– If possible, avoid sudden braking directly after washing the vehicle. You must “dry” the brakes by applying the brakes care-
fully several times ⇒page 169, “Braking effect and braking
distance”.
WARNING
•
The ignition must always be switched off before the vehicle is washed.
•
Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of
injury.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident.Caution
•
Never attempt to remove dirt, mud or dust if the surface of the vehicle is
dry. Never use a dry cloth or sponge for cleaning purposes. This could scratch
the paintwork or glass on your vehicle.
•
Washing the vehicle in cold weather: if the vehicle is rinsed with a hose,
do not direct the water into the lock cylinders or the gaps around the doors,

Cleaning the engine compartment
Take special care when cleaning the engine compartment.Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the car is
frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after the salting period.
Your Authorised Service Centre is able to provide the correct cleaning and
preserving products and has the necessary equipment. For this reason, we
recommend having this work performed by them.
The anti-corrosion protection is usua lly removed if the engine compartment
is cleaned with grease removing solution s, or if you have the engine cleaned.
If this job is carried out, you should ensure that all surfaces, seams, joints and
components in the engine compartmen t are given anti-corrosion treatment
afterwards.
WARNING
•
When working in the engine compartment, always observe the safety
warnings ⇒ page 193
•
Switch off the engine, apply the parking brake firmly and always
remove the key from the ignition before you open the bonnet.
•
Allow the engine to cool before you clean the engine compartment.
•
Do not clean the underside of vehicle, wheel arches without protecting
your hands and arms. You may cut your self on sharp-edged metal parts.
Failure to comply could result in injury.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. If possible, avoid sudden braking immediately after washing
the vehicle.
•
Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason,
engine washing should be carried out only by a qualified workshop or a suit-
able filling station.Care of the vehicle interiorCleaning plastic parts and the dash panel– Use a clean, damp cloth to clean plastic parts and the dash panel.
– If this does not provide satisfactory results, use a special solvent-free plastic cleaning product.
WARNING
Never clean the dash panel and surface of the airbag module with cleansers
containing solvents. Solvents cause the surface to become porous. If the
airbag inflates, disintegrating plastic parts can cause substantial injuries.

192containing additives. These additives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.DieselDiesel*Diesel fuel must correspond to DIN EN 590 (EN = “European standard”). It
must have a cetane number (CN) of at least 51. The cetane number indicates
the ignition quality of the diesel fuel.
Notes on filling with fuel ⇒page 190.RME fuel*
Only those vehicles fitted with special equipment (number PR
2G0 for biodiesel use) may use biodiesel corresponding to
the standard DIN EN 14214.The biodiesel fuel must comply with the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
• DIN is a German abbrev iation for “Deuts che
s In s
titut für Normug e.V .”, the
German standards institute.
•
EN means E uropean Norm.
• FAME is the English abbrev iation “Fatty Acid
Methy l Este r” If the date sticker of the vehicle includes the number PR 2G0 optional equip-
ment) this means that that vehicle has been prepared for biodiesel use.
Your Authorised Service Centre or automobile association will be able to
advise on where you can obtain RME biodiesel fuel.
Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•
The performance of a vehicle using biodiesel maybe somewhat reduced.
•
Fuel consumption of a vehicle using biodiesel maybe slightly higher.
•
RME fuel can be used in winter at
temperatures down to approx. -10°C.
•
At outside temperatures below -10°C, we recommend using winter diesel
fuel.Caution
•
RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.
•
If you decide to use biodiesel in your vehicle, please use only RME fuel
which is DIN E 14,214 compliant.
•
If you use biodiesel that does not me et the required standard, the fuel
filter could become clogged.Note
•
In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.
•
The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend that, about every 300 or 400 km, following a fuel
change, also change the fuel filter. Also. note the instructions in the inspec-
tion and maintenance plan.

•
If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to paraffin separation.
For this reason, “winter-grade diesel fuel” is available in some countries
during the cold months. It can be used at temperatures as low as -22
° C.
In countries with different climatic cond itions the diesel fuel sold generally
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, 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 additives) 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 stick 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 195.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 qualified 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 that you have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 186. The engine compartment of any motor vehicle is a
hazardous area ⇒ .

WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger 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 gea r stick 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 241. 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.
•
Always make sure you have not left any objects, such as cleaning cloths
and tools, in the engine compartment.
•
If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicl e, 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 belt s, 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.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. 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 changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!

208charge. 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 may be fatally explosive. 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 frost. 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 bonnet and open the battery cover at the front ⇒ in
“Safety instructions on working in the engine compartment” on
page 193 ⇒ in “Warnings on handling the battery” on
page 207.
– 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 show n in the corresponding engine compart-
ment diagram ⇒page 252.
The round window (“magic eye”) on the top of the battery changes colour,
depending on the charge level and electrolyte level of the battery.
If the colour in the window is colourless or bright yellow, the electrolyte level
of the battery is too low. Have the battery checked by a qualified workshop.
The colours green and black are used by the workshops for diagnostic
purposes.

behind a cover at the left-hand end of the dash panel and on the left-hand
side of the engine compartment.
The electric windows are protected by circuit breakers. These reset automat-
ically after a few seconds when the overload (caused for example by frozen
windows) has been corrected. Colour coding of fuses
WARNING
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could re
sult in fire. This could also cause
damage to other parts of the electrical system.
Note
•
If a newly replaced fuse blows again after a short time, the electrical
system must be checked by a qualified workshop as soon as possible.
•
If you replace a fuse with a stronger fuse, you could cause damage to
another location in the electrical system.

How to jump startIn ⇒ fig. 172, the flat battery is A and the charged battery B.
Jump lead terminal connections
– Switch off the ignition on both vehicles ⇒.
1. Connect one end of the red jump lead to the positive ⇒fig. 172
terminal of the vehicle with the flat battery ⇒.
2. Connect the other end of the red jump lead to the positive terminal in the vehicle providing assistance.
3. Connect one end of the black jump lead to the negative terminal on the battery of the vehicle providing assistance. 4. Connect the other end of the black jump lead to a solid metal
component which is bolted on to the engine block, or onto the
engine block itself of the vehicle with the flat battery. Do not
connect it to a point near the battery ⇒.
5. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
6. Start the engine of the vehicle with the boosting battery and let
it run at idling speed.
7. Start the engine of the car with the flat battery and wait one or two minutes until the engine is “running”.
Removing the jump leads
8. Before you remove the jump leads, switch off the headlights (if they are switched on).
9. Turn on the heater blower and rear window heater in the vehicle with the flat battery. This helps minimise voltage peaks which are
generated when the leads are disconnected.
10. When the engine is running, disconnect the leads in reverse order to the details given above.
Connect the battery clamps so they ha ve good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
