e fluid s

pecifications
SEAT have developed a special brake fluid
optimised for the brake systems of their vehi-
cles. To ensure the optimum working of the
brake system, SEAT recommends the use of
brake fluid in accordance with the VW 501 14
standard. If this brake fluid is not available or
another brake fluid is used for different rea-
sons, use a brake fluid that complies with the
United States standard FMVSS 116 DOT 4 or
the German standard DIN ISO 4925 CLASS 4
››› .
Br ak
e fluid

s conforming to the standard
VW 501 14, fulfil the American requirements
of the FMVSS 116 DOT 4 standard and the
German DIN ISO 4925 CLASS 4 standard.
However, fluids that comply with the Ameri-
can FMVSS 116 DOT 4 standard or the Ger-
man DIN ISO 4925 CLASS 4 standard do not
necessarily comply with the VW 501 14
standard. Always check the information on
the brake fluid container and ensure that you
are using suitable brake fluid.
A suitable brake fluid can be obtained from
SEAT dealerships. Brake fluid level
The level

of the brake fluid should always be
between the MIN and MAX marks, or above
the MIN mark ››› .
It i
s

not always possible to check the level of
the brake fluid, as in some models the en-
gine components make it difficult to see the
brake fluid reservoir. If you cannot read the
exact brake fluid level, consult a specialist.
The brake fluid level drops slightly when the
vehicle is being used due to wear of the
brake pads and the automatic readjustment
of the brake.
Changing the brake fluid
The brake fluid should be changed in accord-
ance with the instructions given in the Main-
tenance Programme. Have the brake fluid
changed by a specialised workshop. SEAT
recommends taking your car in for technical
service. This means that only brake fluid
complying with the required specifications
will be used. WARNING
If the brake fluid level is low or unsuita-
bl e/o

ld brake fluid is used, the brake system
may fail or braking power may be reduced.
● Check the brake system and the brake fluid
level
regularly! ●
The brak e fluid shou

ld be changed regular-
ly in accordance with the instructions given
in the Maintenance Programme.
● Always ensure that you use suitable brake
fluid. Only u
sed brake fluid that conforms to
the VW 501 14 standard, FMVSS 116 DOT 4
standard or even the DIN ISO 4925 CLASS 4
standard. Other types of brake fluid could af-
fect brake operation and reduce braking pow-
er. Do not use a brake fluid if the container
does not specify compliance with the
VW 501 14, FMVSS 116 DOT 4 or
DIN ISO 4925 CLASS 4 standards.
● The replacement brake fluid must be new.
● Brake fluid should be stored in the closed
original
container in a safe place out of reach
of children. Risk of poisoning!
● If the brake fluid is left in the system for
too long and the br
akes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid damages the vehicle paintwork.
Wipe off an

y brake fluid from the paintwork
immediately. For the sake of the environment
Brake fluid is an environmental pollutant.
Co l

lect any spilt service fluids and allow a
professional to dispose of them. 192

WARNING
Working on the vehicle battery and the elec-
trica l

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 al
l 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 sk
in 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 workin
g with cables and electrical devi-
ces.
● Never short the battery terminals. ●
Never u se a d

amaged battery. It can ex-
plode. Replace a damaged battery immedi-
ately.
● Replaced damaged or frozen batteries as
soon as po
ssible. A flat battery can also
freeze at temperatures close to 0 °C (+32 °F). CAUTION
● Nev er di s

connect 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 lon
g 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

Replacing a vehicle battery
The battery has been developed to suit the
conditions of its location and has special
safety features. If the battery must be re-
placed, consult a technical service for infor- mation on electromagnetic compatibility, the
size and m

aintenance, performance and
safety requirements of the new battery in
your vehicle before you purchase one. SEAT
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

Advice
Different control lamps may light up after
c onnectin
g the b
attery 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 86. Respect the maximum service in-
tervals permitted ››› Booklet Maintenance
Programme.
Automatic 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-
ternat
or provides more electricity.
● Where necessary, the power to the most
power
ful devices is reduced or even com-
pletely disconnected.
● On starting the engine, the power supply
from the 12-v
olt 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 park

ing lights are left on while the
vehicle is stationary.
Why the battery runs flat:
● When stationary for a long time without
star
ting the engine, particularly if the ignition
is switched on.
● Use of electrical devices with the engine
switc
hed off. WARNING
Incorrectly securing the battery or using the
wron g b

attery can cause short-circuits, fire
and serious injuries.
● Always use only maintenance-free batter-
ies, prot
ected 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-
le a

sed when the battery is under charge.
● The batteries should be charged in a well-
ventil
ated room only.
● Never charge a frozen or recently thawed
batter
y. 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 shor
t circuit. Reconnect first the posi-
tive cable and then the negative cable. CAUTION
● Never di s

connect 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 a
s 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 m anner

. Batteries contain toxic sub-
stances such as sulphuric acid and lead. For the sake of the environment
Battery acid can contaminate the environ-
ment. C o

llect any spilt service fluids and dis-
pose of them correctly. 196

refer to one specific vehicle.
They are only to be used to compare the val-
ues of the different vehicle versions. The fuel
consumption and CO 2 emissions of a vehicle
not only depend on the effective use of fuel.
They also depend on your driving style and
other non-technical factors.
Calculation of fuel consumption
Fuel consumption and emission values are
determined according to the current version
of the 715/2007/EC or 80/1268/EEC regula-
tion and are valid for the vehicle kerb weight.
The specifications do not refer to an individu-
al vehicle. To measure the fuel consumption,
two measuring cycles are carried out on a
rolling road test bed. The test criteria are as
follows:
