In the engine compartment: Engine
oil filler cap. Preparations
● Park the vehicle on flat ground so that the
engine oil reading is correct.
● The engine must be hot to be able to check
the engine oil level. Stop the engine and wait a few minutes for the oil to drain back into
the sump.
●
Open the bonnet  ››› page 143.
● The engine oil filler neck can be recognised
by the symbol  on the cap
›
›› Fig. 108 and
the dipstick by its coloured handle.
Check the engine oil level
● Pull out the dipstick and wipe it on a clean
cloth.
● Replace the dipstick, pushing it in as far as
it will go. If the dipstick to measure engine oil
has a mark, when you reintroduce it this
mark should slot into the corresponding
groove located on the upper end of the tube.
● Remove the dipstick again and check the
engine oil level ››› table on page 148.
● After reading the oil level, replace the dip-
stick in the tube completely.
Engine oil topping up ranges
Fig. 107Operations required depending on
the engine oil level:
Area ADo not top up oil
››› .
Area BYou can add oil, but keep the level in this
zone.
Area COil
must be added. After topping up the oil
level should be in area B. Adding oil after checking the level
Only add engine oil in small quantities and in
steps:
●
Unscrew the cap from engine oil filler neck
on the cylinder head ››› Fig. 108 . If you are
not s

ure where the cap is, request help from
a specialist.
● Only refill using approved SEAT engine oil
in small quantities (no more than 0.5 ltr)
››› page 147.
● To av

oid adding too much oil, each time
you add a quantity, wait until the oil has flow-
ed into the crankcase so that it can be meas-
ured with the dipstick.
● Check the oil level before adding any more
oil. Do not top up with too much engine oil
››› .
● When the oil level is in at least the
››› Fig. 107 B zone, insert the dipstick into
the tube fully to avoid engine oil escaping
when the engine is running.
● After topping up the oil, ensure that the
cap is screwed on to the filler neck correctly. WARNING
Oil could catch fire if it comes into contact
with hot engine components. This could lead
to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the
engine oil filler cap is correctly tightened. 148

Checking and refilling levels
This will avoid engine oil spilling onto hot
engine parts when the engine is running.
CAUTION
● If the engine oil level is above the area Ado not start the engine. Seek specialist assis-
tance. Otherwise catalytic converter and en-
gine damage may occur.
● When refilling or changing service liquids,
ensure that you put the liquids into the right
tank. Making a mistake when refilling could
cause serious malfunctions and damage the
engine! 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. Engine oil consumption
The consumption of engine oil can be differ-
ent from one engine to another and can vary
during the useful life of the engine.
Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 1 ltr./2000 km. In the
case of new vehicles, the consumption can
exceed this figure over 5,000 kilometres. For
this reason the engine oil level must be checked at regular intervals, preferably when
filling the tank and before a journey.
When the engine is working hard, for in-
stance during sustained high-speed motor-
way cruising in summer or when climbing
mountain passes, the oil level should pref-
erably be kept within area
››› Fig. 107 A .
Changing the engine oil The engine oil must be changed regularly ac-
cording to the specifications of the Mainte-
nance Programme.
Due to the problems linked with disposing of
used oil and the need for suitable tools and
special knowledge, always visit a specialised
workshop to have the engine oil and filter
changed. SEAT recommends taking your car
in for technical service.
Detailed information on the service intervals
is shown in the Maintenance Programme.
Engine oil additives make new oil darker after
the engine has been running for a short peri-
od. This is normal and does not mean more
frequent oil changes are required.
WARNING
If, in exceptional circumstances, you must
change the engine oil yourself, please note
the following: ●
Wear eye protection.
● Always wait until the engine has complete-
ly cooled to avoid being burned.
● Always keep your arms horizontal when un-
screwing the oil drainage bolt so that it does
not run down your arms.
● Use a suitable container large enough to
collect all of the used oil in the engine.
● Never collect engine oil in empty food con-
tainers, cans, bottles or other containers as
not all people are able to identify engine oil.
● Oil is toxic and must be kept out of the
reach of children. For the sake of the environment
Before changing the engine oil, find a suita-
ble location or service for proper disposal. For the sake of the environment
Always dispose of engine oil with the utmost
respect for the environment. Never dispose of
used engine oil in places such as a garden,
woods, drains, roads, paths, rivers and drain-
age systems. 149Technical specifications

Engine coolant Introduction WARNING
Engine coolant is toxic!
● Only keep engine coolant in its original
container, tightly shut and in a safe place.
● Never store engine coolant in empty food
containers or bottles as other people may ac-
cidentally drink it.
● Always keep engine coolant out of reach of
children.
● Ensure that the proportion of engine cool-
ant additive corresponds to the lowest out-
side temperature to which the vehicle will be
exposed.
● If the outside temperature is extremely low,
the engine coolant could freeze causing the
vehicle to stop. As this would also cause the
heating to stop working, vehicle occupants
without warm clothing could freeze. For the sake of the environment
Coolants and additives can contaminate the
environment. Collect any spilt fluids in suita-
ble containers and dispose of them in accord-
ance with legislation and with the utmost re-
spect for the environment. Coolant warning lamp

Observe the safety warnings ››› in Control
and warning lamps on page 40. Note
On the display of the Portable Navigation
System (supplied by SEAT) ››› page 123 an en-
gine coolant temperature gauge can be seen. 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
150

Checking and refilling levels
reduce the frost protection and, in turn, de-
crease the 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 p lu
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 in
which the vehicle is to be used.
● When the outside temperature is very low,
the coolant could freeze and the vehicle
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 engine coolant level and

Checking and refilling levels
recommends you have the battery replaced
by a technical service.
Use only maintenance-free genuine batteries
conforming to TL 825 06 and VW 7 50 73
Standards. These standards must be dated
April 2008 or later.
Vehicles fitted with the Start-Stop system are
equipped with a special battery. Therefore,
this battery must only be replaced by another
with the same specifications.
Disconnecting the vehicle's battery
If you must disconnect the battery from the
electrical system, please note the following:
● Switch off the ignition and all electrical
equipment.
● The vehicle must be unlocked before dis-
connecting the battery, otherwise the alarm
will be triggered.
● First disconnect the negative cable and
then the positive ››› .
Connecting the vehicle's battery
● Before reconnecting the battery, switch off
the engine and all electrical devices.
● First reconnect the positive cable and then
the negative ››› .
Different control lamps may light up after
connecting the battery and switching the ig-
nition on. They will be turned off after a short trip at a speed of between 15-20 km/h
(10-12 mph). If the warning indicators remain
lit, please visit a specialised workshop to
have the vehicle checked.
If the battery has been disconnected for a
long time, it is possible that the next service
date is not displayed or calculated correctly
››› page 36 . Respect the maximum service in-
t er
vals permitted ››› Booklet Maintenance
Programme.
Autom

atic device disconnection
The intelligent vehicle electrical system auto-
matically implements a range of measures to
prevent the battery from discharging when
high demands are made on it:
● The idling speed is increased so that the al-
ternator provides more electricity.
● Where necessary, the power to the most
powerful devices is reduced or even com-
pletely disconnected.
● On starting the engine, the power supply
from the 12-volt power sockets and the ciga-
rette lighter may be interrupted for a short
time.
The on-board management program cannot
always prevent the battery from running flat.
For example, if the ignition is left on for a
long period with the engine off or if the side
lights or parking lights are left on while the
vehicle is stationary. Why the battery runs flat:
●
When stationary for a long time without
starting the engine, particularly if the ignition
is switched on.
● Use of electrical devices with the engine
switched off. WARNING
Incorrectly securing the battery or using the
wrong battery can cause short-circuits, fire
and serious injuries.
● Always use only maintenance-free batter-
ies, protected to prevent a leak, and whose
properties, specifications and size corre-
spond to the standard battery. WARNING
A highly explosive mixture of gases is re-
leased when the battery is under charge.
● The batteries should be charged in a well-
ventilated room only.
● Never charge a frozen or recently thawed
battery. A flat battery can also freeze at tem-
peratures close to 0 °C (+32 °F).
● Always replace a battery which has frozen.
● Battery cables not correctly connected may
cause a short circuit. Reconnect first the posi-
tive cable and then the negative cable. » 157

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.
● Never plug accessories that supply current,
such as solar panels or a battery charger, to
the 12-volt power socket or the cigarette
lighter. This could damage the vehicle's elec-
trical system. For the sake of the environment
Dispose of the battery in an environment-
friendly manner. Batteries contain toxic sub-
stances such as sulphuric acid and lead. For the sake of the environment
Battery acid can contaminate the environ-
ment. Collect any spilt service fluids and dis-
pose of them correctly. Wheels and tyres
Wheels Introduction SEAT recommend that all work on tyres and
wheels is carried out by a specialised work-
shop. These workshops have the necessary
special tools and replacement parts, trained
personnel and facilities for disposing of the
old tyres while respecting the environment.
SEAT recommends taking your car in for tech-
nical service.
WARNING
The vehicle cannot be totally controlled or
braked if the tyres (new or used) are worn or
damaged.
● Incorrect use of wheels and tyres could
make driving more dangerous and result in
serious accidents and damage.
● All four wheels must be fitted with radial
tyres of the same type, size (rolling circumfer-
ence) and the same tread pattern.
● New tyres do not give maximum grip and
will not have reached their maximum braking
capacity to start with, and therefore need
running in. To prevent accidents and major
damage, extreme caution should be taken for
the first 600 km. ●
Check tyre pressures regularly and ensure
they are maintained at the pressures indica-
ted. If the tyre pressure is too low, they could
overheat, resulting in tread detachment or
even burst tyres.
● Never drive on damaged (punctured, cut,
cracked or dented) or worn tyres. Driving on
damaged or worn tyres could result in burst
tyres, serious accidents or damage. Worn or
damaged tyres must be replaced immediate-
ly.
● Never exceed the maximum permitted
speed or loads specified for the type of tyre
fitted on your vehicle.
● The effectiveness of driver and brake assist
systems also depends on the grip of the
tyres.
● If you notice unusual vibration or if the ve-
hicle pulls to one side when driving, stop the
car immediately and check the tyres and
wheels for damage.
● To minimise the risk of losing control of the
vehicle or causing a serious accident, never
undo the bolted joints of beadlock wheels.
● Never mount used tyres or wheels if you are
not sure of their previous history. They may
be damaged, although the damage is not im-
mediately visible.
● Old tyres, even if they have never been
used, may lose air or burst unexpectedly
while driving, especially at high speeds, re-
sulting in serious accident and injury. If tyres
are over six years old, they should only be
used in an emergency and with extreme cau-
tion. 158

Wheels and tyres
Wheel rims with bolted trims
Wheel rims may be fitted with interchangea-
ble trim parts which are attached to the rim
using self-locking bolts. Worn trims should
only be replaced at a specialised workshop.
SEAT recommends visiting a technical service
››› .
WARNING
The use of worn or damaged wheel rims could
make driving more dangerous and result in
serious accidents and damage.
● Only wheel rims which have been approved
for use with your vehicle should be used.
● Inspect wheel rims regularly for damage
and replace as required. WARNING
If the bolted joints of wheel rims with bolted
ring trims are not correctly tightened or loos-
ened, this could result in serious accident.
● Never loosen the bolted joints of wheel
rims with bolted ring trims.
● Any work relating to wheel rims with bolted
rims should be carried out at specialised
workshop. SEAT recommends taking your car
in for technical service. Replacement of wheel rims and new
tyres
New tyres
● When tyres are new, drive with extreme
caution for the first 600 km, as all tyres need
to be run-in . Tyres which have not been run-
in do not
have such good grip ››› or brak-
ing capacity ››› .
● All four wheels must be fitted with radial
tyres of the same type, size (rolling circumfer-
ence) and the same tread pattern.
● The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Replacing tyres
● Where possible, always replace both
wheels on an axle (both wheels on the front
axle or both wheels on the rear axle) ››› .
● Only replace used tyres with those author-
ised by SEAT for the corresponding type vehi-
cle. Pay special attention to size, diameter,
and maximum load and speed capacity.
● Never use tyres which are larger than SEAT
approved tyres. If the tyres are too big, they
may knock or rub against the chassis or other
components, resulting in damage. WARNING
New tyres do not give maximum grip and will
not have reached their maximum braking ca-
pacity to start with, and therefore need run-
ning in.
● To prevent accidents and major damage,
extreme caution should be taken for the first
600 km. WARNING
There should be adequate space between the
tyres and the vehicle in accordance with the
vehicle design. If this is not the case, the
tyres may rub against parts of the running
gear, chassis or brake lines, leading to faults
in the brake system or to tread detachment,
and the risk of burst tyres.
● The true tyre dimension should not be
greater than the dimensions of tyres manu-
factured and approved by SEAT and should
not rub against parts of the vehicle. Note
Although tyres may be shown as being the
same size, the true dimensions of different
types of tyre may vary with respect to the
nominal size, or tread patterns may be differ-
ent. Note
If you use tyres that are approved by SEAT,
you can be sure that the true tyre dimensions » 161Technical specifications

will be correct for your vehicle. For other tyre
models, the tyre vendor should provide the
manufacturer's certificate with the tyre, indi-
cating that this type of tyre is suitable for
your vehicle. This certificate should always
be carried with the vehicle.
Tyre pressures
Fig. 115
Position of tyre pressure specifica-
tion plate The correct tyre pressures for tyres fitted at
the factory is shown on a label and is valid
for summer and winter tyres. The label ›››
Fig. 115 is located on the driver's door pil-
l ar
.
Under-inflation or over-inflation will reduce
the life of the tyres considerably and also im-
pair the car's handling ››› . It is essential to
maintain the correct tyre pressures, especial-
ly if driving at high speeds. Incorrect tyre
pressure causes premature wear and could
cause tyre blow-out.
The pressure should therefore be checked at
least once a month and before starting a
journey.
As a general rule, the pressures given are for
cold tyres . When the tyres are hot, the pres-
s ur

es are greater.
Never deflate a hot tyre in order to obtain the
required pressure. This could result in very
low tyre pressures which may lead to sudden
blow-outs.
Checking tyre pressures
Check tyre pressures only when the vehicle
has not been driven for more than a few kilo-
metres at low speeds in the past three hours.
● The tyre pressures should be checked regu-
larly, and only when the tyres are cold. Al-
ways check all tyres, including the spare
wheel. Tyre pressures should be checked
more often in colder regions, and only when
the vehicle has not been driven recently. Al-
ways use a correctly-operating tyre gauge. ●
Adjust tyre pressures to the loads carried in
the vehicle.
● After adjusting the tyre pressure, check that
the caps are properly screwed on.
The
spare wheel or temporary spare wheel
must be at the maximum pressure specified. WARNING
If tyre pressures are too high or too low, the
tyre may deflate or burst suddenly while driv-
ing. This could result in a serious accident.
● If the tyre pressure is too low, they could
overheat, resulting in tread detachment or
even burst tyres.
● When driving at high speeds and/or fully
loaded, the tyre could suddenly overheat,
burst or be subject to tread detachment, with
the resultant loss of control of the vehicle.
● Tyre pressures which are too high or too
low reduce the service life of the tyre, affect-
ing the vehicle's performance.
● Tyre pressures should be checked regularly,
at least once a month and before long jour-
neys.
● Adjust the pressures of all the tyres to the
vehicle load.
● Never deflate excess pressure from hot
tyres. 162
