WARNING
Working on the vehicle battery and the elec-
trical system can cause corrosion, fire and electric shocks. Always read and take into ac-
count the following warnings and safety
standards before carrying out any work:
●
Before working on the battery, switch off
the engine, the ignition and all electrical de-
vices then disconnect the negative connec-
tion on the battery.
● Keep children away from acid and the bat-
tery itself!
● Wear eye protection.
● Battery acid is very corrosive and caustic. It
can burn skin and cause blindness. When
handling the battery, protect yourself from
splashes of acids, above all your hands, arms
and face.
● Do not smoke and never work close to pla-
ces exposed to flames or sparks.
● Avoid sparks and electrostatic discharges
when working with cables and electrical devi-
ces.
● Never short the battery terminals.
● Never use a damaged battery. It can ex-
plode. Replace a damaged battery immedi-
ately.
● Replaced damaged or frozen batteries as
soon as possible. A flat battery can also
freeze at temperatures close to 0 °C (+32 °F). 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 car is left standing for long periods,
protect the battery from extreme cold temper-
ature so that it does not “freeze up” and be-
come damaged. Warning lamp

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

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

Advice
Foreign bodies in the tyre
● Do not remove foreign bodies if they have
penetrated through the tyre wall!
● You should obtain professional assistance
immediately.
Wear of tyres
The wear of tyres depends on a number of
factors, for example:
● Driving style.
● Unbalanced wheels.
● Running gear settings.
Driving style : Driving round bends quickly or
sudden acceleration or braking speed accel-
erates tyre wear. When the driving style is
normal, if the tyres wear too quickly, have the
running gear settings checked at a special-
ised workshop.
Wheel run-out : The wheels on new vehicles
ar e b
alanced. However, certain circumstan-
ces may lead to imbalance (run-out), which is
detected as vibrations in the steering wheel.
Run-out leads to wear of the steering and
suspension. In the event of run out, the
wheels should be balanced again. When a
new wheel is fitted, it should be balanced
again.
Running gear settings : an incorrectly posi-
tioned running gear increases the wear of
tyres and affects your safety while driving. If tyres wear too quickly, have the wheel align-
ment checked at a specialised workshop. WARNING
If you notice unusual vibration or the car pulls
to one side while driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
observing the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Request qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitoring system* 
Fig. 117
Centre console: tyre monitor system
button The tyre control lamp compares wheel revolu-
tions and with it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp

lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheels of one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 117 button must
be k ept
pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.

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. »

od must comply with traffic legislation. WARNING
A faulty vehicle in traffic represents a risk of
accident for the driver and for other road
users.
● Stop the vehicle safely as soon as possible.
Park the vehicle a safe distance from sur-
rounding traffic to lock all the doors in case of
an emergency. Turn on the hazard warning
lights to warn other road users.
● Never leave children or disabled people
alone in the vehicle if the doors are to be
locked. In case of an emergency, passengers
will be trapped inside the vehicle. Individuals
locked in the vehicle can be exposed to very
high or very low temperatures. WARNING
The components of the exhaust system reach
very high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as dried grass or
fuel). Note
● The vehicle battery will discharge and run
down if the hazard warning lights remain on
for too long (even with the ignition turned
off). ●
For some vehicles, the brake lights will
blink when braking suddenly at speeds of ap-
proximately 80 km/h (50 mph) to alert vehi-
cles to the rear. If braking continues, the haz-
ard warning lights system will automatically
be turned on at a speed of less than approxi-
mately 10 km/h (6 mph). The brake lights re-
main lit. Upon accelerating, the hazard warn-
ing lights will be automatically turned off. Vehicle tool kit*
