Care and maintenance
Products for vehicle maintenance
Car-care products are available in your Tech-
nical Services. Keep the product instructions
until you have used them up. WARNING
● Car-care products can be toxic. Because of
this, they must always be kept closed in their
original container. Keep them out of the reach
of children. Failure to comply could result in
poisoning.
● Always read and observe the instructions
and warnings on the package before using
car-care products. Improper use could cause
health problems or damage the vehicle. The
use of certain products may produce noxious
vapours; they should be used in well ventila-
ted areas.
● Never use fuel, turpentine, engine oil, nail
varnish remover or other volatile fluids.
These are toxic and highly flammable. Risk of
fire and explosion.
● Before washing your vehicle, or carrying
out any maintenance, switch the engine off,
apply the handbrake firmly and remove the
key from the ignition. 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 damage the paintwork or the win-
dows of your vehicle. Soak dirt, mud or dust
with plenty of water. For the sake of the environment
● When purchasing products for your vehicle
maintenance, select the ones which are not
harmful to the environment.
● The waste from car-care products should
not be disposed of with ordinary household
waste. Observe the disposal information on
the package. Care of the vehicle exterior
Automatic car washing tunnel The vehicle paintwork is so durable that the
vehicle can normally be washed without
problems in an automatic car wash tunnel.
However, the paintwork wear depends to a
large extent on the kind of the car wash tun-
nel, the brushes used, its water filtering and
the type of cleaning and preservative prod-
ucts.
Before going through a car wash, be sure to
take the usual precautions such as closing
the windows and sunroof. There is nothing to
note apart from that.
If the vehicle has special accessories such as
spoilers or a roof rack or two-way radio aerial,
etc., it is advisable to consult the car wash
tunnel operator first.After washing, the brakes could take some
time to respond as the brake discs and pads
could be wet, or even frozen in winter. “Dry”
the brakes by braking several times. WARNING
Water, ice and salt on the brake system can
reduce braking effectiveness. Risk of acci-
dent. CAUTION
Before putting the vehicle through the car
wash, do not tighten the aerial if it is folded
because it can be damaged. Washing by hand
Vehicle washing
– First soften the dirt and rinse it off with wa-
ter.
– Clean your vehicle from top to bottom with
a soft sponge, a glove or a brush. Use very
light pressure.
– Rinse the sponge or glove often with clean
water.
– Special car shampoo should only be used
for very stubborn dirt.
– Leave the wheels, sill panels etc. until last,
using a different sponge or glove.

The essentials

Advice
– Rinse the vehicle thoroughly with water.
– Dry the vehicle surface gently with a cha-
mois leather.
– In cold temperature
, dry the rubber seals
and their s
urfaces to prevent them from
freezing. Apply silicone spray to the rubber
seals.
After washing the vehicle – After washing, avoid sudden and sharp
braking. “Dry” the brakes by braking sever-
al times. WARNING
● Wash your vehicle with the ignition switch-
ed off.
● Protect your hands and arms from cuts on
sharp metal edges when cleaning the under-
body, the inside of the wheel housings etc.
Risk of injury.
● Water, ice and salt on the brake system can
reduce braking effectiveness. Risk of acci-
dent. CAUTION
● Never remove dirt, mud or dust if the vehi-
cle surface is dry. Never use a dry cloth or
sponge for cleaning purposes. This could
scratch the paintwork or glass on your vehi-
cle. ●
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 the environment, the vehicle
should be washed only in specially provided
wash bays, to prevent toxic, oil-laden waste
water from entering the sewer 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
di s

tance.
– Increase the spraying distance for soft ma-
terials and painted bumpers. –
Do not use a high pressure cleaner to re-
move ice or snow from windows
››› page 159.
– Never u

se concentrated jet nozzles (“rotat-
ing jets”) ››› .
– After washing, avoid sudden and sharp
braking. “Dry” the brakes by braking sever-
al times ››› page 126 . WARNING
● Never wash tyres with a concentrated jet
(“rotating nozzle”). Even at large spraying
distances and short cleaning times, damage
can occur to the tyres. This may cause an ac-
cident.
● Water, ice and salt on the brake system can
reduce braking effectiveness. Risk of acci-
dent. CAUTION
● Do not use water hotter than +60 °C
(+140 °F). This could damage the vehicle.
● To avoid damage to the vehicle, keep a suf-
ficient distance from sensitive materials such
as flexible hoses, plastic, soundproofing ma-
terial, etc. This also applies to bumpers pain-
ted in the colour of the bodywork. The closer
the nozzle is to the surface, the greater the
wear on the material. 158

Advice
●
The heating element for the rear window is
located on the inner side of the window. To
prevent damage, do not put stickers over the
heating elements on the inside of the win-
dow. Cleaning windscreen wiper blades
Clean wiper blades improve visibility.
1. Use a soft cloth to remove dust and dirt
from the windscreen wiper blades.
2. Use window cleaner to clean the wind- screen wiper blades. Use a sponge or a
cloth to remove stubborn dirt.
Rubber seals maintenance If rubber seals are well looked after, they will
not freeze so quickly.
1. Use a soft cloth to remove dust and dirt
from the rubber seals.
2. Apply a specialist care product to the rub- ber seals.
The rubber strips on the doors, windows, etc.
will remain pliable and last longer if they are
treated with a suitable rubber care product
from time to time (for example silicone
spray). Caring for rubber seals will also prevent pre-
mature ageing and leaks. The doors will be
easier to open. If rubber seals are well looked
after, they will not freeze so quickly in winter.
Door lock cylinders The door lock cylinders can freeze up in win-
ter.
To de-ice the lock cylinders you should only
use spray with lubricating and anti-corrosive
properties.
Cleaning chrome parts 1. Clean chrome parts with a damp cloth.
2. Polish chrome parts with a soft, dry cloth.
If this does not provide satisfying results, use
a specialist
chrome cleaning product.
Chrome cleaning products will remove stains
from the surface. 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 distances and short clean-
ing times, damage can occur to the tyres.
This may cause an accident.
● Water, ice and salt on the brake system can
reduce braking effectiveness. Risk of acci-
dent. Directly after washing, avoid sudden
and sharp braking. “Dry” the brakes by brak-
ing several times ››› page 126, 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 3 months
– Apply a hard wax compound to the wheels.
160

Care and maintenance
Alloy wheels require regular attention to pre-
serve their appearance. If road salt and brake
dust are not often removed, the aluminium
finish will be impaired.
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 damaged area should be re-
paired immediately. WARNING
Observe the safety warnings ››› in Steel
wheel rims on page 160. 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 that you check the
protective coating under the body and on the
running gear, and retouch it if necessary, be-
fore and after the winter season.
We recommend that you go to your Technical
Service to carry out repair work and addition-
al anti-corrosion work. WARNING
Do not apply underseal or anti-corrosion
coatings to the exhaust pipes, catalytic con-
verter or the heat shields on the exhaust sys-
tem. 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 treat-
ment at the factory.
Good corrosion protection is particularly im-
portant in winter when the vehicle is fre-
quently driven on salted roads. To prevent
the salt corroding the vehicle, the entire en-
gine compartment should be thoroughly
cleaned before and after winter.
Technical Services
have the proper products
for cleaning and preservation as well as the
necessary workshop equipment. For this rea-
son, we recommend having this work per-
formed by them.
The anti-corrosion protection is usually re-
moved 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 com-
partment are given anti-corrosion treatment.
WARNING
● When working in the engine compartment,
always observe the safety warnings
››› page 166.
● Bef
ore opening the bonnet, switch the en-
gine off, apply the handbrake firmly and al-
ways remove the key from the ignition.
● Allow the engine to cool before you clean
the engine compartment.
● Do not clean, for example, the vehicle un-
derbody, 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 effectiveness. Risk of acci-
dent. Directly after washing, avoid sudden
and sharp braking.
● Never touch the radiator fan. It is tempera-
ture-controlled and could start automatically,
even when the key is removed from the igni-
tion! For the sake of the environment
Fuel, grease and oil deposits can be removed
when the engine is washed. The polluted wa-
ter must be cleaned in an oil separator. For
this reason, engine washing should be » 161

Filter pre-heater
Your vehicle is fitted with a fuel filter glow
plug system, making it well equipped for op-
eration in winter. This ensures that the fuel
system remains operational to approx. -24 °C
(-11 ºF), provided you use winter-grade die-
sel which is safe to -15 °C (+5 °F).
However, if the fuel has waxed to such an ex-
tent that the engine will not start at tempera-
tures of under -24 °C (-11 °F), simply place
the vehicle in a warm place for a while. CAUTION
Do not mix fuel additives, the so-called “thin-
ners”, or similar additives with diesel fuel. Working in the engine
compartment
Safety instructions on working in the
engine compartment Before starting any work on the engine or in
the engine compartment:
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 selec- tor lever to position P. 4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet
››› page 167.
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. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service
fluids and consumables replaced by a Techni-
cal Service. Please observe the relevant in-
structions ››› page 155 . The engine compart-
ment of
the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
partment, e.g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even 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 electri-
cal system, particularly at the points where
the jump leads are attached ››› page 188. The
battery could explode.
● Never touch the radiator fan. It is tempera-
ture controlled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition!
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion 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 ob-
jects, such as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to 166

Checking and refilling levels
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing 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:
– 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-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. 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 components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. 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 the envi-
ronment. 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 speci-
alised workshop. Opening the bonnet

The layout of parts may vary depending on
the engine. Engine oil
General notes The engine comes with a special, multi-grade
oil that can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.

Checking and refilling levels
●
When working in the engine compartment,
always observe the safety warnings
››› page 166.
● When the en gine i
s warm or hot, the cool-
ing system is pressurised! Do not unscrew
the cap on the coolant expansion tank when
the engine is hot. This is a burn injury risk. CAUTION
● If you notice a change in the colour of the
liquid because it has been in use for a long
time, it is recommended to change it, as it
will have lost some of its properties and
could cause damage to the engine.
● If a lot of coolant fluid has been lost, wait
for the engine to cool. This avoids damaging
the engine. Large coolant losses are an indi-
cation of leaks in the cooling system. See a
specialised workshop immediately and have
the cooling system checked. Otherwise, there
is a risk of engine damage. Brake fluid
Checking the brake fluid level Read the additional information carefully
›››  page 25
The position of the brake fluid reservoir is
shown in the corresponding engine compart- ment illustration
››› page 168 . The brake fluid
r e

servoir has a black and yellow cap.
The brake fluid level drops slightly when the
vehicle is being used as the brake pads are
automatically adjusted as they wear.
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. A
display on the instrument panel will warn you
if the brake fluid level is too low ››› page 57. WARNING
Before opening the bonnet to check the brake
fluid level, read and observe the warnings
››› page 166. Changing the brake fluid
The Maintenance Programme indicates brake
fluid change intervals.
We recommend that you have the brake fluid
changed by a Technical Service.
Before opening the bonnet, please read and
follow the warnings
››› in Safety instruc-
tions on working in the engine compartment
on page 166 in section “Safety notes for
w ork

ing in the engine compartment”.
In the course of time, brake fluid becomes
hygroscopic and absorbs water from the am-
bient air. If the water content in the brake flu- id is too high, the brake system could cor-
rode. This also considerably reduces the boil-
ing point of the brake fluid. Heavy use of the
brakes may then cause a vapour lock which
could impair the braking effect.
Be sure to always use the correct brake fluid.
Only use brake fluid that expressly meets the
VW 501 14 standard.
You can buy VW 501 14 standard brake fluid
in a SEAT dealership or a SEAT Official Serv-
ice. If none is available, use only high-quality
brake fluid that meets DIN ISO 4925 CLASS 4
standards, or USA Standards FMVSS 116 DOT
4.
Using any other kind of brake fluid or one
that is not of a high quality may affect opera-
tion of the brake system and reduce its effec-
tiveness. Never use a brake fluid if the con-
tainer does not state that it complies with VW
501 14, DIN ISO 4925 CLASS 4 standards, or
USA standards FMVSS 116 DOT 4.
WARNING
Brake fluid is poisonous. Old brake fluid im-
pairs the braking effect.
● Before opening the bonnet to check the
brake fluid level, read and observe the warn-
ings ››› page 166.
● Br ak
e fluid should be stored in the closed
original container in a safe place out of reach
of children. There is a toxic risk. » 173

Advice
●
Perform the brake fluid change according to
the Maintenance Programme. Heavy use of
the brakes may cause a vapour lock if the
brake fluid is left in the brake system for too
long. This would seriously affect the effec-
tiveness of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid damages the vehicle paintwork.
Wipe off any brake fluid from the paintwork
immediately. For the sake of the environment
The brake pads and brake fluid must be col-
lected and disposed of according the applica-
ble regulations. The SEAT Technical Service
network has the necessary equipment and
qualified personnel for collecting and dispos-
ing of this waste material. Windscreen washer reservoir
Topping up washer fluid Read the additional information carefully
›››  page 25
The windscreen washer
and the headlight
washers are supplied with fluid from the
windscreen washer fluid container in the en-
gine compartment. The container holds ap- prox. 2 litres; in vehicles with headlight
washers* it holds approx. 4.5 litres.
The tank is in the engine compartment.
Plain water is not enough to clean the wind-
screen and headlights. We recommend that
you always add a product to the windscreen
washer fluid. Approved windscreen cleaning
products exist on the market with high deter-
gent and anti-freeze properties, these may be
added all-year-round. Please follow the dilu-
tion instructions on the packaging.
WARNING
Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously.
● When working in the engine compartment,
always observe the safety warnings
››› page 166. CAUTION
● Never put radiator anti-freeze or other addi-
tives into the windscreen washer fluid.
● Always use approved windscreen cleansing
products diluted as per instructions. If you
use other washer fluids or soap solutions,
the tiny holes in the fan-shaped nozzles
could become blocked. Vehicle battery
Warnings on handling the battery 
Wear eye protection

Battery acid is extremely corrosive. Wear protec-
tive gloves and eye protection!

Fires, sparks, open flames and smoking are pro-
hibited!

A highly explosive mixture of gases is released
when the battery is under charge.

Keep children away from acid and batteries!
WARNING
Always be aware of the danger of injury and
chemical burns as well as the risk of accident
or fire when working on the battery and the
electrical system:
● Wear eye protection. Protect your eyes,
skin and clothing from acid and particles con-
taining lead.
● Battery acid is extremely corrosive. Wear
protective gloves and eye protection. Do not
tilt the batteries. This could spill acid through
the vents. Rinse battery acid from eyes imme-
diately for several minutes with clear water.
Then seek medical care immediately. Neutral-
ise any acid splashes on the skin or clothing
with a soapy solution, and rinse off with plen-
ty of water. If acid is swallowed by mistake,
consult a doctor immediately. 174

Advice
Depending on the make, there will be 6 to 8
of them evenly spaced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. 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 177.
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 advisable to change
them around as shown ››› Fig. 155 . The use-
f u
l life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration. Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced 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 Tech-
nical Service.
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 indicators are worn
››› page 177. Failure to follow this instruction
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 in-
sufficient 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 pressures.
● 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 re-
placed immediately! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. 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. Those approved
by SEAT are specially matched to the charac-
teristics of the vehicle and make a major con-
tribution to good road-holding and safe han-
dling
››› .
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 des-
ignations makes it easier to choose the cor-
rect tyres. Radial tyres have the tyre designa-
tions marked on the sidewall, for example: 195/65 R15 91T
