Introduction WARNING
Incorrectly handling engine oil can cause in-
jury and serious burns.
● Always protect your eyes when handling
engine oil.
● Oil is toxic and must be kept out of the
reach of children.
● Engine oil should only be kept in its origi-
nal packaging; the same goes for used oil un-
til it is disposed of. 146

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

Tyres that are over 6 years old
Tyres are subject to an ageing process as a
result of physical and chemical processes.
This may affect their performance. Tyres
which are stored for long periods of time
without being used, harden and become
more fragile than tyres which are in constant
use.
SEAT recommends that tyres over six years
old are replaced with new tyres. This also ap-
plies to tyres (including the spare wheel)
which appear to be in perfect condition on
the outside and which have a tread depth
within the values stipulated by the Law ››› .
The date of manufacture, part of the tyre
identification number (TIN), indicates the age
of the tyre ( ) ››› page 167 .
St orin
g tyres
Mark tyres when you remove them to indicate
the direction of rotation (left, right, forwards,
backwards). This ensures you will be able to
mount them correctly when you replace
them. When removed, the wheels and/or
tyres should be stored in a cool, dry and pref-
erably dark location. Do not place tyres
mount

ed on the wheel in a vertical position.
Protect tyres not mounted on wheels from
dirt by storing them in suitable bags and
standing them on the ground on their tread. WARNING
Aggressive fluids or substances could result
in visible or invisible damage with the conse-
quent risks.
● Always ensure that tyres do not come into
contact with chemical products, oil, grease,
fuel, brake fluid or other aggressive substan-
ces. WARNING
Old tyres, even if they have never been used,
may lose air or burst unexpectedly while driv-
ing, resulting in serious accident or damage.
● If tyres are over six years old, they should
only be used in an emergency and with ex-
treme caution. For the sake of the environment
Old tyres must be disposed of by qualified
personnel according to the laws in the coun-
try concerned. Wheel rims
The design of wheel bolts is matched to the
rims. If different rims are fitted, the correct
wheel bolts with the right length and correct-
ly shaped bolt heads must be used. This en-
sures that wheels are fitted securely and that
the brake system functions correctly
››› page 174 . F
or t
echnical reasons, it is not generally pos-
sible to use the wheels from other vehicles.
In some cases, this may also be true for the
same model of wheel.
The tyres and rims approved by SEAT are spe-
cially matched to the characteristics of the
vehicle and are critical to good road holding
and safe handling.
Note for Italy:
A SEAT Service Centre should
be consulted whether different sized wheels
or tyres to those originally fitted by SEAT may
be fitted, as well as the combinations al-
lowed between the front axle (axle 1) and
back axle (axle 2).
Wheel bolts
Wheel bolts must be tightened to the correct
torque ››› page 174
.
Beadlock wheel rims
Beadlock wheel rims have various compo-
nents. These are joined together by special
bolts using a special procedure. This ensures
good performance, a better seal, improved
safety and wheel run out. Therefore, worn
rims should always be replaced and must on-
ly be repaired in a specialised workshop.
SEAT recommends visiting a technical service

Wheels and tyres
The tyre pressure control lamp  lights up
If the ty
re pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ››› will light up.
WARNING
● When the tyre pressure control lamp lights
up, reduce speed immediately and avoid any
sudden turning or braking manoeuvre. Stop
when possible, and check the tyre pressure
and status.
● The driver is responsible for maintaining
correct tyre pressures. For this reason, tyre
pressure must be regularly checked.
● Under certain circumstances (e.g. when
driving in a sporty manner, in winter condi-
tions or on a dirt track) the tyre control lamp
may light up belatedly or may function incor-
rectly. Note
If the battery is disconnected, the yellow
warning lamp  lights up after turning the
ignition on.

This should turn off after a brief
journey. Spare wheel or temporary spare

direction, and t
ake out the spare wheel. Storing the replaced wheel
● Pull back the carpet.
● With the wheel rim facing downwards, sit-
uate the replaced wheel in the spare wheel
well so that the wheel rim central hole coin-
cides with the opening.
● Turn the hand controlled wheel with the
shank screwed clockwise until the replaced
wheel is secured.
● If necessary, store the vehicle tool in the
container, inside the boot.
● Replace the carpet on the boot floor.
● Lower the rear shelf.
● Close the rear lid.
If the spare wheel is different to the rest of
the vehicle tyres
If the spare tyre is not the same as the tyres
that are mounted on the vehicle - for example
with winter tyres or the temporary spare
wheel - you should only use the spare tyre for
a short period of time and drive with extra
care ››› .
Refit the normal road wheel as soon as possi-
ble.
Please observe driving advice:
● Do not drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fast cornering. »

● Snow chains on the temporary spare wheel
are not permitted ››› page 169 .
● Af t
er mounting the spare wheel or the tem-
porary spare wheel, check the tyre pressure
as soon as possible ››› page 162.
It is advisable to check the spare wheel or
temporary spare wheel tyre pressure when
checking the rest of the vehicle wheels at
least once a month. The spare wheel should
have the highest pressure allowed for the ve-
hicle ››› page 162. The sticker situated on the
temporary spare wheel shows the tyre pres-
sure. WARNING
Incorrect handling of the spare wheel or the
temporary spare wheel can cause loss of ve- hicle control, producing collisions or other
serious accidents and injury.
●
Never use the spare wheel or the temporary
spare wheel if it is damaged or worn to the
wear indicator.
● In some vehicles the spare wheel is smaller
than the original tyres. This can be seen on a
sticker showing the text “80 km/h” and
“50 mph”. This text indicates the maximum
velocity permitted for this type of tyre.
● Never drive faster than 80 km/h (50 mph).
Avoid powerful acceleration, hard braking
and taking corners at high speed.
● Never drive more than 200 km with a tem-
porary spare wheel fitted to the drive axle.
● Replace the temporary spare wheel for a
normal wheel as soon as possible. The com-
pact temporary spare wheel is only intended
for temporary use over short distances. ●
The temporary spare wheel must always be
secured with the factory supplied wheel
bolts.
● You should never use more than one tem-
porary spare wheel.
● After mounting the temporary spare wheel,
check the tyre pressure as soon as possible
››› page 162.
● Sno w c

hains on the temporary spare wheel
are not permitted. Note
Wherever possible, secure the spare wheel,
temporary spare wheel or the replaced wheel
safely in the luggage compartment. In vehi-
cles with anti-puncture kit, it is not possible
to secure the defective wheel. 166

› . Important information about wheel bolts
The wheel rims and bolts have been de-
signed to be fitted to factory options. If differ-
ent 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 some circumstances, wheel bolts from the
same model vehicle should not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is
110 Nm
.
Hav e the tight

ening torque of the wheel bolts
checked as soon as possible with a reliable
torque wrench.
If wheel bolts are rusty and it is difficult to
tighten them, the threads should be replaced
and cleaned before checking the tightening
tor

que.
Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not fitted correctly they
could be released while driving leading to
loss of vehicle control and serious damage. ●
Only use wheel bolts which correspond to
the wheel rims in question.
● Never use different wheel bolts.
● The bolts and threads should be clean, free
of oil and grease and easy to thread.
● To loosen and tighten the wheel bolts, al-
ways use the wheel brace supplied with the
vehicle.
● Loosen the wheel bolts only about one turn
before raising the vehicle with the jack.
● Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving.
● Never loosen the bolted joints of wheel
rims with bolted ring trims.
● If the wheel bolts are not tightened to the
correct torque, they may come loose while
driving, and the bolts and rims may come
out. If the tightening torque is too high, the
wheel bolts and threads can be damaged. 176
