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.
The specifications (VW standards) set out on
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.
We recommend that the oil change indicated
in the Maintenance Programme be performed
by a technical service or a specialised work-
shop.
The correct oil specifications for your engine
are listed in the
›››
page 167, Oil properties .Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6,
this means that your vehicle is programmed
with the LongLife service. If it lists the codes
QI1, QI2, QI3, QI4 or QI7, the interval service
is dependent on time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on characteristics
and individual driving profiles, allow for
greater intervals between oil change services
(LongLife service intervals).
Because this oil is essential for extending the
service intervals, it
must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
tervals.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 167 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals › ›
›
page 167 (up to a maximum of 0.5 li-
tres).

Checking and refilling levels
Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for fixed service
intervals , which also appear in
›
› › page 167,
Oil properties . In this case, your vehicle must
be serviced after a fixed interval of 1
year/15 000 km (10 000 miles)(whatever
comes first) ››› Booklet Maintenance Pro-
gramme.
● In ex

ceptional circumstances, if the engine
oil level is too low ››› page 167 and you can-
not o

btain the oil specified for your vehicle,
you can put in a small quantity of oil con-
forming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or
ACEA B4 (diesel engines) (up to 0.5 l).
Vehicles with a diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.
Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 167 and you cannot obtain the oil specified for your
vehicle, you can use a small quantity of oil
(once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or
ACEA B3/ACEA B4 specification. (up to 0.5 l).

Engine oil additives
No type of additive should be mixed with the
engine oil. The deterioration caused by these
additives is not covered by the warranty. Note
Before a long trip, we recommend finding an
engine oil that conforms to the correspond-
ing VW specifications and recommend keep-
ing it in the vehicle. This way, the correct en-
gine oil will always be available for a top-up if
needed. Checking the engine oil level

Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 0.5 l/1000 km. Oil
consumption is likely to be higher for the first
5,000 km. For this reason the engine oil level
must be checked at regular intervals, prefera-
bly when filling the tank and before a jour-
ney. WARNING
Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously. –

nents when topping up. CAUTION
If the oil level is above the area A do not
start the engine. This could result in damage
to the engine and catalytic converter. Contact
a specialised workshop. For the sake of the environment
The oil level must never be above area A .
Otherwise oil can be drawn in through the
crankcase breather and escape into the at-
mosphere via the exhaust system. 168

Checking and refilling levels
Changing engine oil The engine oil must be changed at the inter-
vals given in the service schedule.
We recommend that you have the engine oil
changed by a Technical Service.
The oil change intervals are shown in the
Maintenance Programme.
WARNING
Only change the engine oil yourself if you
have the specialist knowledge required!
● Before opening the bonnet, read and ob-
serve the warnings ››› page 163, Safety in-
structions on working in the engine compart-
ment.
● Wait
for the engine to cool down. Hot oil
may cause burn injuries.
● Wear eye protection to avoid injuries, such
as acid burns, caused by splashes of oil.
● When removing the oil drain plug with your
fingers, keep your arm horizontal to help pre-
vent oil from running down your arm.
● Wash your skin thoroughly if it comes into
contact with engine oil.
● Engine oil is poisonous! Used oil must be
stored in a safe place out of the reach of chil-
dren. CAUTION
No additives should be used with engine oil.
This could result in engine damage. Any dam-
age caused by the use of such additives
would not be covered by the factory warranty. For the sake of the environment
● Because of disposal problems and the spe-
cial tools and specialist knowledge required,
we recommend that you have the engine oil
and filter changed by a Technical Service.
● Never pour oil down drains or into the
ground.
● Use a suitable container when draining the
used oil. It must be large enough to hold all
the engine oil. Cooling system
Engine coolant specifications The engine cooling system is supplied from
the factory with a specially treated mixture of
water and, at least, 40 % of the additive
G 13
(TLVW 774 J). The engine coolant additive is
recognisable by its purple colour. This mix-
ture of water and additive gives the necessa-
ry frost protection down to -25°C (-13 F) and
protects the light alloy parts of the cooling
system against corrosion. It also prevents scaling and considerably raises the boiling
point of the coolant.
To protect the engine cooling system, the
percentage of additive must
always be at
l e

ast 40 %, even in warm climates where an-
ti-freeze protection is not required.
If greater frost protection is required in very
cold climates, the proportion of additive can
be increased. However, the percentage of ad-
ditive should not exceed 60%, as this would
reduce frost protection and, in turn, decrease
cooling capacity.
When the coolant is topped up, use a mixture
of distilled water and, at least, 40 % of the G
13 or G 12 plu

s-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› . The mixture of G
13 with G 12 plus (TL-VW 774 F), G 12 (red) or
G 11 (green-blue) engine coolants will signifi-
cantly reduce the anticorrosion protection
and should, therefore be avoided ››› .
WARNING
If there is not enough anti-freeze in the cool-
ant system, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additive is correct with respect to the lowest
expected ambient temperature in the zone
where the vehicle is to be used.
● When the outside temperature is very low,
the coolant could freeze and the vehicle » 169

would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold.
CAUTION
The original additives should never be mixed
with coolants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system. ● If the fluid in the expansion tank is not pur-
ple but is, for example, brown, this indicates
that the G 13 additive has been mixed with
an inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. For the sake of the environment
Coolants and additives can contaminate the
environment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Checking the coolant level and
topping up
Fig. 149
Engine compartment: coolant expan-
sion tank cap. Top up coolant when the level is below the
MIN (minimum) mark.
Before opening the bonnet, read and observe
the warnings
››› in Safety instructions on
working in the engine compartment on
page 163 .
Openin g the c
oolant expansion tank
– Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the
coolant expansion tank with a thick cloth
and carefully unscrew the cap ››› .
Checking coolant level
– Look into the open coolant expansion tank
and read off the coolant level. –
If the level is below the “MIN” mark, top up
with coolant.
Topping up coolant – Only use new coolant liquid.
– Do not fi

ll above the “MAX” mark.
Closing the coolant expansion tank – Screw the cap on again tightly.
The position of the coolant expansion reser-
voir is shown in the corresponding engine
compartment illustration ››› page 166.
Make sure that the coolant meets the re-
quired specifications ››› page 169. Do not use
a different type of additive if additive G12+ is
not available. In this case use only water and
bring the coolant concentration back up to
the correct level as soon as possible by put-
ting in the specified additive ››› page 169.
Always top up with new coolant.
Do not fi

ll above the “MAX” mark. Otherwise
the excess coolant will be forced out of the
cooling system when the engine is hot.
The coolant additive G12+ (dyed purple) may
be mixed with G12 (dyed red) and also with G
11.

Checking and refilling levels
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 163.
● When the engine is 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
● When mixed with other additives the colour
of G12 will change to brown. If this occurs
you should have the coolant changed imme-
diately. Failure to do so will result in engine
damage!
● If a lot of coolant fluid has been lost, wait
for the engine to cool. This avoids damaging
the en gine. Lar
ge 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. Windscreen washer reservoir

In the engine compartment: Cap of
windscreen washer fluid reservoir 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. 3 litres; in vehicles with headlight
washers* it holds approx. 5.5 litres.
The reservoir is located on the right-hand
side of 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 163. 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. 171

Brake fluid Checking the brake fluid level Fig. 151
Engine compartment: brake fluid
reservoir cap –
Read off the fluid level at the transparent
brake fluid reservoir. It should always be
between the “MIN” and “MAX” marks.
The position of the brake fluid reservoir is
shown in the corresponding engine compart-
ment illustration ››› page 166. The brake fluid
reservoir 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 35. WARNING
Before opening the bonnet to check the brake
fluid level, read and observe the warnings
››› page 163. 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 163 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
at 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 163.
● 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.
● 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. 172

Checking and refilling levels
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

qualified personnel for collecting and dispos-
ing of this waste material. Vehicle battery
Warnings on handling the battery Wear eye protection

Battery acid is extremely corrosive. Wear pro-
tective gloves and eye protection!

Fires, sparks, open flames and smoking are
prohibited!

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.
● Fires, sparks, open flames and smoking are
prohibited. When handling cables and electri-
cal equipment, avoid causing sparks and
electrostatic charge. Never short the battery
terminals. High-energy sparks can cause in-
jury.
● A highly explosive mixture of gases is re-
leased when the battery is under charge. The
batteries should be charged in a well-ventila-
ted 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 electrical devices. 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 unlock-
ing the vehicle before you disconnect the bat-
tery! The alarm will otherwise be triggered.
● When disconnecting the battery from the
vehicle on-board network, disconnect first
the negative cable and then the positive ca-
ble. ●
Switch off all electrical devices before re-
connecting 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 also
freeze at temperatures close to 0 °C (+32 °F).
● Ensure that the vent hose is always connec-
ted to the battery.
● Never use a defective battery. This could
cause an explosion. Replace a damaged bat-
tery 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 components.
● Do not expose the battery to direct sunlight
over a long period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
● If the vehicle is left standing in cold condi-
tions for a long period, protect the battery
from “freezing”. If it freezes it will be dam-
aged. 173

Checking the electrolyte level The electrolyte level should be checked regu-
larly in high-mileage vehicles, in hot coun-
tries and in older batteries.
– Open the bonnet and open the battery cov-
er at the front ››› in Safety instructions
on working in the engine compartment on
page 164 ››› in Warnings on handling
the battery on page 173.
– 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 compartment diagram
››› page 166 .
The “m agic
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 specialised 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 special-
ist knowledge.
If you often drive short distances or if the ve-
hicle is not driven for long periods, the bat-
tery 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 rec-
ommend you have the vehicle battery
checked by a Technical Service where it will
be re-charged or replaced.
Charging the battery
The vehicle battery should be charged by a
specialised workshop only, as batteries us-
ing special technology have been installed
and they must be charged in a controlled en-
vironment.
Replacing a vehicle battery
The battery has been developed to suit the
conditions of its location and has special
safety features.
Genuine SEAT batteries meet the mainte-
nance, 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
2001.
● Before starting any work on the batteries,
you must read and observe the warnings
››› in Warnings on handling the battery on
page 173. For the sake of the environment
Batteries contain toxic substances such as
sulphuric acid and lead. They must be dis-
posed of appropriately and must not be dis-
posed of with ordinary household waste. 174

Advice
●
Never start the engine when the vehicle is
on the jack. Risk of accident.
● If work is to be carried out underneath the
vehicle, this must be secured by suitable
stands. Otherwise, there is a risk of injury. Note
The jack does not generally require any main-
tenance. If required, it should be greased us-
ing universal-type grease. Compact spare wheel* (temporary
spare wheel)
Fig. 154
Luggage compartment. Accessing
the spare wheel. The compact spare wheel (temporary spare
wheel for vehicles without the anti-puncture
kit) should only be used when strictly neces-
sary. The temporary spare wheel is stored under
the floor panel in the luggage compartment
and is attached by a thumbnut.
How to use the temporary spare wheel
Should you ever have a punctured tyre, the
compact temporary spare wheel is only inten-
ded for temporary use until you can reach a
workshop. The standard-size road wheel
should be replaced as soon as possible.
Please note the following restrictions when
using the temporary spare wheel. This tem-
porary spare wheel has been specially de-
signed for your vehicle, thus, it cannot be re-
placed by a temporary spare wheel from an-
other vehicle.
No other type of tyre (normal summer or win-
ter tyre) may be fitted on the compact tempo-
rary spare wheel rim.
Snow chains
For technical reasons, snow chains must
not
be used on the compact temporary spare
wheel.
If you have a puncture on one of the front
wheels when using snow chains, fit the com-
p act
temporary spare wheel in place of one of
the rear wheels. You can then attach the
snow chains to the wheel taken from the rear
and use this wheel to replace the punctured
front wheel. WARNING
● The tyre pressures must be checked and
corrected as soon as possible after fitting the
temporary spare wheel. The pressure of the
spare wheel sized 125/70R16 125/70R18
135/90R16 should be 4.2 bar
(61 psi/420 kPa). For other sizes, check the
label on the fuel cap. Failure to follow this in-
struction could result in an accident.
● Do not drive faster than 80 km/h (50 mph),
since higher speeds can cause an accident.
● Avoid heavy acceleration, hard braking and
fast cornering. Risk of accident.
● Never use more than one temporary spare
wheel at the same time, risk of accident.
● No other type of tyre (normal summer or
winter tyre) may be fitted on the compact
temporary spare wheel rim. Wheel change
Preparation work –
If you have a flat tyre or puncture, park the
vehicle as far away from the flow of traffic
as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the ve-
hicle. They should wait in a safe area (for
instance behind the roadside crash barri-
er).
