Vehicle maintenance and cleaning
WARNING
● Wash your vehicle with the ignition switched off.
● Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of in-
jury.
● Water, ice and salt on the brake system can reduce braking effective-
ness. Risk of accident.
CAUTION
● Never remove dirt, mud or dust if the vehicle surface 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 low temperatures: when washing the vehicle
with a hose, do not direct water into the lock cylinders or the gaps around
the doors, rear lid, or sunroof. Risk of freezing.
For the sake of the environment
To protect environment, the vehicle should be washed only in specially pro-
vided wash bays. This prevents toxic, oil-laden waste water entering the
sewerage system. In some places, washing vehicles outside wash bays is
prohibited.
Note
Do not wash the vehicle in direct sunlight. Washing the vehicle with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!
– Always observe the instructions for the high-pressure cleaner,
particularly those concerning the pressure and the spraying
distance.
– Increase the spraying distance for soft materials and painted
bumpers.
– Do not use a high pressure cleaner to remove ice or snow from
windows ⇒ page 184.
– Never use concentrated jet nozzles (“rotating jets”) ⇒ 
.
– After washing, avoid sudden and sharp braking. “Dry” the
brakes by braking several times ⇒ page 173.
WARNING
● Never wash tyres with a concentrated jet (“rotating nozzle”). Even at
large spraying distances and short cleaning times, visible and invisible
damage can occur to the tyres. This may cause an accident.
● Water, ice and salt on the brake system can reduce braking effective-
ness. Risk of accident.
CAUTION
● Do not use water hotter than 60°C. This could damage the vehicle.
● To avoid damage to the vehicle, keep a sufficient distance from sensitive
materials such as flexible hoses, plastic, soundproofing material, etc. This
is also important for bumpers painted in the colour of the bodywork. The
closer the nozzle is to the surface, the greater the wear on the material. 

186Vehicle maintenance and cleaning
CAUTION
To prevent scratching chrome surfaces:
● Never use an abrasive cleaning product on chrome.
● Do not clean or polish chrome parts in a sandy or dusty environment. 
Steel wheel rims
– Clean steel wheel rims regularly using a separate sponge.
Use an industrial cleaner to remove brake dust. Any damage to the paint on
steel wheel rims should be repaired before starting to rust.
WARNING
● Never wash tyres with a cylindrical jet. Even at large spraying distan-
ces and short cleaning times, visible and invisible damage can occur to
the tyres. This may cause an accident.
● Water, ice and salt on the brake system can reduce braking effective-
ness. Risk of accident. Directly after washing, avoid sudden and sharp
braking. Dry the brakes by braking several times ⇒ page 173, Braking ca-
pacity and braking distance.

Alloy wheel rims
Every two weeks
– Wash salt and brake dust from alloy wheels.
– Use an acid free detergent to clean the wheel rims. Every three months
–
Apply a hard wax compound to the wheels.
Alloy wheels require regular attention to preserve their appearance. If road
salt and brake dust are not often removed, the aluminium finish will be im-
paired.
Always use an acid-free detergent for alloy wheel rims.
Car polish or other abrasive agents should not be used for maintaining the
rims. If the protective coating is damaged, e.g. by flying stones, the dam-
aged area should be repaired immediately.
WARNING
● Never wash tyres with a cylindrical jet. Even at large spraying distan-
ces and short cleaning times, visible and invisible damage can occur to
the tyres. This may cause an accident.
● Water, ice and salt on the brake system can reduce braking effective-
ness. Risk of accident. Directly after washing, avoid sudden and sharp
braking. Dry the brakes by braking several times ⇒ page 173, Braking ca-
pacity and braking distance.

Underbody protection
The vehicle underbody is coated to protect it from chemical
and mechanical damage.
The protective coating can be damaged when driving. We recommend you
to check the protective coating under the body and on the running gear, and
reinstated if necessary, before and after the winter season.
We recommend you to go to your Technical Service to carry out repair work
and additional anti-corrosion work. 

187
Vehicle maintenance and cleaning
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite. Risk of fire.

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 vehi-
cle is frequently driven on salted roads. To prevent the salt corroding the ve-
hicle, the entire engine compartment should be thoroughly cleaned before
and after winter.
Your Technical Services have got the necessary workshop equipment to pro-
vide the correct cleaning and preserving products. For this reason, we rec-
ommend having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine
cleaned. On commissioning this work, ensure that all surfaces, seams,
joints and components in the engine compartment are given anti-corrosion
treatment.
WARNING
● When working in the engine compartment, always observe the safety
warnings ⇒ page 200.
● Before opening the bonnet, switch the engine off, apply the hand-
brake firmly and always remove the key from the ignition.
● Allow the engine to cool before you clean the engine compartment.
● Do not clean the vehicle underbody, wheel arches or wheel trims
without protecting your hands and arms. You may cut yourself on sharp-
edged metal parts. Failure to comply could result in injury.
● Moisture, ice and salt on the brake system may affect braking effec-
tiveness. Risk of accident. Directly after washing, avoid sudden and
sharp braking.
● 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, en-
gine washing should be carried out only by a specialised workshop or a pet-
rol station. 
Vehicle interior maintenance Plastic parts and dash panel cleaning
– Use a clean, damp cloth to clean plastic parts and the dash
panel.
– If this does not provide satisfactory results, use a special sol-
vent-free plastic cleaning product. 

Checking and refilling levels
The LPG tank ⇒ Fig. 129 in the spare wheel well has a capacity of 52.8 li-
tres. If the outside temperatures are very low, it may not be possible to com-
pletely fill the LPG tank.
Pump attachments
There are a variety of types of LPG pump, and the methods of use may vary.
Therefore, let the pump operator fill the tank when refuelling for the first
time or fill from another pump.
Noises when refuelling with LPG
When refuelling with LPG, noises may be heard. These noises are insignifi-
cant.
WARNING
Failure to refuel or handle LPG in the correct way could result in a fire,
cause an explosion or lead to injuries.
● LPG is a highly explosive and inflammable substance. It may cause
severe burns and other injury.
● Switch off the engine before refuelling.
● Always switch off mobile phones and any other radiophony applian-
ces, as electromagnetic waves may produce sparks and cause a fire.
● Do not remain in the vehicle while refuelling. If it is absolutely neces-
sary to enter the vehicle, close the door and touch a metal surface before
touching the attachment again. This will prevent the generation of static
electricity and any possible fires while refuelling.
● Small quantities of LPG may leak out after refuelling. If LPG comes in-
to contact with skin, there is a risk of freezing.
● Do not smoke and always keep bare flames away from the tank during
refuelling. Failure to do so may lead to an explosion.
 Adapter for the liquid petroleum gas (LPG) filler neck
An adapter is required due to the existence of a range of
pumps with different nozzles.
Fig. 130 General table of LPG filler neck adapters.
ACME adapter (adapter for Europe)
Dish Coupling Adapter (adapter for Italy)
Bayonet adapter
EURO adapter (adapter for Spain)
The supply includes the adapter for the country in question, the ACME 1
,
the Dish Coupling 2, the bayonet 3 or the EURO adapter 4.
The filler systems and corresponding adapters vary according to country. As
petrol stations abroad do not always have the necessary adapters for your
LPG system, we recommend you purchase the appropriate adapter before
travelling abroad. Check that the adapters are suited to your filling system. 

● Black: correct charge status.
● Transparent/clear yellow: the battery must be replaced. Contact a speci-
alised workshop. 
Charging and changing the vehicle battery
The battery is maintenance-free and is checked during the
inspection service. All work on the vehicle battery requires
specialist knowledge.
If you often drive short distances or if the vehicle is not driven for long peri-
ods, the battery should be checked by a specialised workshop between the
scheduled services.
If the battery has discharged and you have problems starting the vehicle,
the battery might be damaged. If this happens, we recommend you have
the vehicle battery checked by a Technical Service where it will be re-charg-
ed or replaced.
Charging the battery
The vehicle battery should be charged by a specialised workshop only, as
batteries using special technology have been installed and they must be
charged in a controlled environment.
Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and
has special safety features.
Genuine SEAT batteries fulfil the maintenance, performance and safety
specifications of your vehicle.
WARNING
● We recommend you use only maintenance-free or cycle free leak-proof
batteries which comply with standards T 825 06 and VW 7 50 73. This
standard applies as of August 2001.
● Before starting any work on the batteries, you must read and observe
the warnings ⇒ 
in Warnings on handling the battery on page 214.
For the sake of the environment
Batteries contain toxic substances such as sulphuric acid and lead. They
must be disposed of appropriately and must not be disposed of with ordi-
nary household waste. 

General notes
Avoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and at a right angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters,
etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in order to maintain the
same direction of rotation when they are installed again. 

217
Checking and refilling levels
– When removed, the wheels and/or tyres should be stored in a
cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel
rims.
New tyres
New tyres must be run in ⇒ page 173.
The tread depth of new tyres may vary, according to the type and make of
tyre and the tread pattern.
Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the vehicle pulling to one side, this may indicate that one of
the tyres is damaged. The tyres should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
● New tyres do not have maximum grip during the first 500 km
(300 miles). Drive particularly carefully to avoid possible accidents.
● Never drive with damaged tyres. This may cause an accident.
● If you notice unusual vibrations or if the vehicle pulls to one side
when driving, stop the vehicle immediately and check the tyres for dam-
age.
 Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the fuel tank flap.
1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially important at high speeds. The pres-
sure should therefore be checked at least once a month and before starting
a journey.
WARNING
A tyre can easily burst if the pressure is too low, causing an accident!
● At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
● If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. 

Tyre useful life
The useful life of tyres is dependent on tyre pressure, driving
style and fitting.
Fig. 142 Tyre tread wear
indicators
Fig. 143 Diagram for
changing wheels Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 142, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 217.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ Fig. 143. The useful life of all the
tyres will then be about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by a Technical Service. 

219
Checking and refilling levels
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 218. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by a Technical Service.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. 
New tyres and wheels
New tyres and wheels have to be run in.
The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteris-
tics of the vehicle and make a major contribution to good road holding and
safe handling ⇒ 
.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example: 195/65 R15 91T
This contains the following information: Tyre width in mm
Height/width ratio in %
Tyre construction: Radial
Rim diameter in inches
Load rating code
Speed rating
The tyres could also have the following information:
● A direction of rotation symbol
● “Reinforced” denotes heavy-duty tyres.
The manufacturing date is also indicated on the tyre sidewall (possibly only
on the inner side of the wheel).
“DOT... 1103...” means, for example, that the tyre was produced in the 11th
week of 2003.
We recommend that work on tyres and wheels be carried out by a Technical
Service. They are familiar with the procedure and have the necessary spe-
cial tools and spare parts as well as the proper facilities for disposing of the
old tyres.
Any Technical Service has full information on the technical requirements
when installing or changing tyres, wheels or wheel trims. 

WARNING
● We recommend that you use only wheels and tyres which have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.
● Avoid running the vehicle on tyres that are more than 6 years old. If
you have no alternative, you should drive slowly and with extra care at all
times.
● Never use old tyres or those with an unknown history of use.
● If wheel trims are retrofitted, you must ensure that the flow of air to
the brakes is not restricted. This could cause the brake system to over-
heat.
● All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.
For the sake of the environment
Old tyres must be disposed of according to the laws in the country con-
cerned.
Note
● For technical reasons, it is not generally possible to use the wheels from
other vehicles. This can also apply to wheels of the same model. The use of
wheels or tyres which have not been approved by SEAT for use with your
model may invalidate the vehicle's type approval for use on public roads.
● If the spare wheel is not the same as the tyres that are mounted on the
vehicle (e.g. winter tyres) you should only use the spare tyre for a short peri-
od of time and drive with extra care. Refit the normal road wheel as soon as
possible. Wheel bolts
Wheel bolts must be tightened to the correct torque.
The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped
bolt heads must be used. This ensures that wheels are fitted securely and
that the brake system functions correctly.
In certain circumstances, you should not use wheel bolts from a different
vehicle, even if it is the same model ⇒ page 190.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.
● The wheel bolts must be clean and turn easily. Never apply grease or
oil to them.
● Use only wheel bolts which belong to the wheel.
● If the prescribed torque of the wheel bolts is too low, they could loos-
en whilst the vehicle is in motion. Risk of accident! If the tightening tor-
que is too high, the wheel bolts and threads can be damaged.
CAUTION
The prescribed tightening torque for wheel bolts for steel and alloy wheels
is 120 Nm. 
