Advice
The brake fluid reservoir is located in the en-
gine c omp
ar
tment of the vehicle.
– Switch the ignition off.
– Open the bonnet ›››
page 204.
– Check the brake fluid level in the reservoir
›››
Fig. 208. It should be between the “MIN”
and “MAX” marks.
The fluid level drops slightly after a period of
time due to automatic compensation for
brake pad wear. This is quite normal.
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. If
the brake fluid level in the reservoir is too
low, this will be indicated by the warning
lamp illuminating on the instrument panel 
››› page 157, Control lamp .WARNING
● If the fluid l ev

el has dropped below the MIN
mark,  do not continue driving. Risk of acci-
dent! Go to a technical service.
● Heavy use of the brakes may cause a va-
pour lock if
the brake fluid is left in the brake
system for too long. This would seriously af-
fect the efficiency of the brakes and the safe-
ty of the vehicle. Changing the brake fluid
Brake fluid absorbs moisture. Therefore, it
gra
dual

ly absorbs moisture from the atmos-
phere. If the water content in the brake fluid
is too high, the brake system could corrode.
The water content also reduces the boiling
point of the brake fluid.
The brake fluid must comply with one of the
following standards or specifications:
● VW 50114
● FMVSS 116 DOT4 CAUTION

Advice
●
A short c
ircuit is produced if the battery ter-
minals are bridged, e.g. using metal objects,
cables, etc. Possible consequences of a short
circuit: melting of lead plates, battery explo-
sion and fire, splashing acid.
● The following is forbidden while working on
the batter
y: fire and open flames, smoking
and activities that could produce sparks.
Avoid causing sparks when handling cables
or electrical apparatus. Risk of injury in the
event of large sparks.
● Before working on the electrical system,
you mus
t switch off the engine, the ignition
and all electrical components and disconnect
the cable from the negative terminal (-) of the
battery. To change a bulb, simply switch off
the corresponding light.
● Never charge a frozen or thawed out bat-
tery
. Risk of explosion and acid burns! Re-
place a frozen battery.
● Never use the jump leads on batteries in
which the electr
olyte level is too low. Risk of
explosion and acid burns!
● Never use a damaged battery. Risk of ex-
plos
ion! Replace a damaged battery immedi-
ately. CAUTION
● Never di s

connect the battery when the igni-
tion is switched on, as the electrical system
(electronic components) of the vehicle could
be damaged. When disconnecting the battery
from the vehicle electrical system, disconnect its negative terminal (-) first. Only then may
the pos
itiv

e terminal (+) be disconnected.
● When connecting the battery, first connect
the positiv
e terminal (+) and then the nega-
tive terminal (-). The battery cables must nev-
er be connected to the wrong battery termi-
nals. Risk of burning the electrical installa-
tion!
● Make sure the battery acid does not come
into cont
act with the bodywork. Risk of paint-
work damage.
● Do not expose the battery to direct sunlight
to prot
ect it from ultraviolet radiation.
● If the vehicle is not used for 3 or 4 weeks,
the batter
y could run flat. This is because
some components use electricity even in
standby mode (e.g. control units). Prevent the
battery from running flat by disconnecting its
negative terminal or leave it charging at a low
current.
● If you frequently use the vehicle for short
trips, the batt
ery may not fully charge and
could run flat. For the sake of the environment
A flat battery is particularly harmful waste for
the env ir

onment. It must therefore be dis-
posed of according to current local law. Note
Replace a battery once it is older than 5
ye ar

s. Control lamp
If the
 control lamp is illuminated while the
en gine i

s running, the battery is not charg-
ing.
Go to a technical service. Have the car's elec-
trical equipment inspected. CAUTION
Additionally, if the warning lamp  lights up
whi
le driving, the warning lamp  also lights
up (cooling system fault). Stop the vehicle
and switch off the engine – Risk of engine
damage! Lifting the battery cover

Checking and refilling levels
– Open the b att
er
y cover in the direction indi-
cated by the arrow ››› Fig. 210.
– The positive terminal (+) of the battery is
connected in r

everse order.
Checking the battery electrolyte level Fig. 211
Battery: Electrolyte level indicator. We recommend you have the acid level regu-
l
arly
c

hecked at an official technical service,
particularly in the following cases.
● At high outside temperatures.
● On long daily trips.
● Whenever the vehicle is loaded
›››
page 215, Charging the battery.
In vehicles equipped with a battery with col-
our indicator, the so-called magic eye
››› Fig. 211 changes colour to indicate the
acid level. Air bubbles can influence the colour of the in-
dicator

. Therefore, carefully knock the indica-
tor before checking the acid level.
● Black – the acid level is correct.
● Colourless or light yellow – acid level too
low, b
attery must be changed. Note
● The batt er

y acid level is also regularly
checked during servicing at authorised SEAT
dealers.
● The electrolyte level on “AGM” batteries
cannot be c
hecked for technical reasons.
● Vehicles equipped with the “Start-Stop”
syst
em include a battery control unit to con-
trol the battery level for repeated engine
starting. Winter service
At low temperatures the battery provides only
a fr
action of
the s

tarting power it has at nor-
mal temperatures.
A flat battery can also freeze at temperatures
slightly below 0°C (+32°F).
We therefore recommend you have the bat-
tery checked and, if necessary, charged at an
official SEAT technical service before the start
of winter. Charging the battery A fully-charged battery is essential for relia-
bl
e s

tarting.
– Switch off the ignition and all electrical
equipment.
– For “f

ast-charging” only: disconnect both
batter
y connection cables (first the “nega-
tive” terminal and then the “positive”).
– Connect the charger cables to the battery
terminal

s (red = “positive”, black = “nega-
tive”).
– Plug in the battery charger and switch on.
– After charging the battery: Switch off the
batt er

y charger and disconnect the cable.
– Remove the charger cables.
– If necessary, reconnect both battery cables
to the batt

ery (first the “positive” cable,
then the “negative” cable).
When charging with a low current (e.g. with a
small battery charger ), the battery does not
normally have to be disconnected. The in-
structions of the battery charger manufactur-
er must be followed.
Use a current equivalent to or lower than
10% of the battery capacity to fully charge
the battery.
Before “fast-charging” the battery however,
both battery cables must be disconnected. »

Advice
“Fast-charging” a battery is dan
g erous and
requires a battery charger and special knowl-
edge. Fast charges should be performed by
an official technical service.
The battery caps should not be opened while
the battery is being charged. CAUTION
In vehicles fitted with the “Start-Stop” sys-
tem, the c h

arger cable cannot be directly con-
nected to the negative terminal of the vehicle
battery but must be attached to the engine
ground point ›››

We recommend having the vehicle checked by
an authorised S EA

T dealer to guarantee the
correct working order of all electrical sys-
tems. Changing the battery
A replacement battery must have the same
cap
ac

ity, voltage, current rating and size as
the original. The appropriate types of battery
can be acquired from authorised SEAT deal-
ers.
We recommend having the battery changed
by an authorised SEAT dealer, where the new
battery will be correctly installed and the
original disposed of in line with regulations.
Automatic disconnection of electrical
equipment When heavily-charging a battery, the pro-
gr
amme sel
ect

ed by the electrical system
control unit prevents the battery from auto-
matically discharging. This may result in the
following:
● Increase in idling speed so that the alterna-
tor can s
upply more current to the electrical
system.
● The performance of certain electrical com-
ponents cou
ld be limited or some may switch
off temporarily, e.g. the heated seats, the
heated rear window, the 12 V power socket. Note
Despite any measures taken by the control
unit, the b att

ery could drain. e.g. with the en- gine is switched off, the key is turned in the
ignition for a lon
g period or the s

ide lights or
parking lights are switched on. The switching
off of certain electrical components does not
impair driving comfort and often the driver
will not even notice. 216

Service life of tyres Fig. 212
Side view of tyres with tread wear in-
dic at
or
s. Fig. 213
Location of the tyre pressure sticker. Tread wear indicator
The b
ase of

the side of the original tyres on
your vehicle show 1.6 mm high tread wear in-
dicators ››› Fig. 212. The position of these in-
dicators is given on the tyre sidewalls by the
letters “TWI”, triangular symbols or other
symbols.
The useful life of the tyres depends primarily
on the following factors:
Tyre pressure values
Under-inflation or over-inflation will consider-
ably reduce the useful life of the tyres and
impair the vehicle's handling. Therefore,
check the tyre pressure, including the spare
wheel, at least once a month and before any
long journey.
Inflation pressures for summer tyres are lis-
ted on a sticker inside the fuel tank flap
››› Fig. 213. The pressures for winter tyres are
0.2 bar (2.9 psi/20 kPa) above the summer
values.
Always check the pressure when the tyre is
cold. Do not reduce over-pressure in warm
tyres. The tyre pressures must be altered to
suit notable changes in the load being car-
ried.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (“comfort” tyre pressure). When driving with comfort tyre pressure fuel con-
sumption ma
y increase slightly.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Wheel balancing
The wheels on new vehicles are balanced.
Various factors encountered when driving
can cause them to become unbalanced,
which results in vibration of the steering
wheel.
The wheel must be rebalanced if a new tyre is
fitted or if a tyre is repaired.
Incorrect wheel alignment
Incorrect front or rear wheel alignment cau-
ses excessive tyre wear, frequently on one
side, and also impairs vehicle safety. If tyre
wear is very irregular, contact an Official
Service.
Tyre damage
To avoid damage to tyres and wheels, only
drive over kerbs or similar obstacles slowly
and at a right angle if possible.
Check tyres and wheels regularly for damage
(punctures, cracks, blisters, deformities,
etc.). Remove any foreign objects embedded
in outside of the treads.
218

Wheels and tyres
Unusual vibration or the car pulling to one
s ide m
a
y indicate that one of the tyres is
damaged. Reduce speed immediately and
stop if you suspect that a wheel may have
been damaged! Check the tyres for damage
(blisters, cracks, etc.). If no external damage
is visible, drive slowly and carefully to the
nearest Official Service and have the vehicle
inspected.
Interchanging tyres Fig. 214
Interchanging tyres. Changing wheels around
If
the w
e

ar is visibly greater on the front tyres,
they should be exchanged for the rear tyres
as shown in the diagram ››› Fig. 214. All the
tyres will then last for about the same time.
To ensure that the wear is equal on all tyres
and maintain their optimum useful life, they
should be changed around every 10 000 km. Storing tyres
When you r

emove the tyres, mark them in or-
der to maintain the same direction of rotation
when they are installed again.
When removed, the wheels and/or tyres
should be stored in a cool, dry and preferably
dark location. Store tyres in a vertical posi-
tion, if they are not fitted on wheel rims.
New tyres or wheels All four wheels must be fitted only with tyres
of
the s
ame type, s

ize and the same tread
pattern.
The correct tyre/wheel combinations speci-
fied for your vehicle are listed in its docu-
mentation.
Understanding the tyre designations makes
it easier to choose the correct tyres. The tyre
designation is marked on the sidewall. For
example.

Follow the instructions ››› page 220 if you
only have a temporary spare wheel. Note
A SEAT Service Centre should be consulted to
find out whether wheel s

or tyres of different
sizes to those originally fitted by SEAT can be
fitted, and to find out about the combinations
allowed between the front axle (axle 1) and
the rear axle (axle 2). Tyres with directional tread pattern
The direction of rotation is indicated by the
arr
o
w

s on the tyre sidewall . The direction of
rotation indicated must be respected. This
guarantees optimum grip and helps avoid ex-
cessive noise, wear and aquaplaning.
In the event of a flat tyre, a spare wheel with
an undetermined tread pattern or an oppo-
site tread pattern must be used and you must
drive carefully, as in these cases the tyres no
longer offer maximum performance. Spare wheel
Spar
e wheel location* Fig. 215
Luggage compartment: spare wheel. The spare wheel is housed in a well under
the floor p
anel
in the lug

gage compartment
and is secured by a special bolt ››› Fig. 215.
Take out the tool box before removing the
spare wheel.
The tyre pressure of the spare wheel must be
checked (preferably whenever the tyre pres-
sure is checked – see sticker on fuel tank flap
››› page 218) to ensure the spare wheel re-
mains ready for use.
If the spare wheel is not the same size or de-
sign as the tyres that are mounted on the car
(for example if the car has winter tyres or
tyres with direction tread), only use the spare
tyre for a short period of time in the event of breakdown and drive with the corresponding
care
›

›› .
It mu
s
t be replaced as soon as possible for a
wheel with a normal size and finish.
Temporary spare wheel
If the vehicle is equipped with a temporary
spare wheel, there will be a warning sign on
the rim of the wheel.
Follow the instructions below when driving
with this wheel fitted.
● After fitting the wheel, the warning sign
must
not be covered.
● Do not drive faster than 80 km/h (50 mph)
with the sp
are wheel and take great care
while driving. Avoid heavy acceleration, hard
braking and fast cornering.
● The tyre pressure is the same as that of the
stand
ard tyres.
● Only use this spare wheel to reach the
neare
st Official Service, as it is not designed
for permanent use. WARNING
● Under no cir c

umstances must damaged
spare wheels be used.
● If the spare wheel is different in size or de-
sign to the ty
res currently fitted, never drive
faster than 80 km/h (50 mph). Avoid heavy
acceleration, hard braking and fast cornering. 220

Wheels and tyres
CAUTION
Follow the instructions given on the tempora-
ry s
pare wheel label. Note
The tyre pressure of the spare wheel must al-
wa y

s correspond to the highest pressure pre-
scribed for the model of vehicle in question. Tyre monitoring systems
Ty r

e pressure* The tyre pressure monitoring system uses
ABS
sen
sor

s to compare the revolutions and
the circumference of each wheel. Should the
circumference of any wheel change, the
warning lamp  on the general instrument
panel will light up and an audible warning
will be heard.
Tyre circumference may change if:
● Tyre pressure is too low
● Tyre structure is damaged
● Vehicle load not evenly distributed
● wheels on one axle are subjected to greater
load, (e.
g. driving with trailer, uphill, down-
hill);
● Snow chains are fitted
● The temporary spare wheel is fitted ●
One wheel on the axl
e has been changed
Basic system settings
Should the tyre pressure change or if one or
more wheels are changed or the position of
the wheel on the vehicle is changed, e.g.
changing round the front and rear wheels, or
where a warning lamp lights up when driv-
ing, the system must be adjusted as follows: ● Inflate all tyres to the prescribed pressures
›››

● Switch the ignition on.
● Store the new tyre pressure in the Easy

 page 21.
● In vehicles without radio : pres
s and hold
down the   button with the ignition on,
until an acoustic signal is heard.
The warning lamp  lights up
If the pressure on at least one tyre is signifi-
cantly lower than the pressure set by the driv-
er, the warning lamp  will light up ››› .
The w arnin
g l

amp  flashes
If the warning lamp flashes, there is a fault in
the system. Contact a specialised service to
have it fixed. WARNING
● If the w arnin

g lamp  lights up, slow down
immediately and avoid any severe braking or
steering manoeuvres. Stop and check the
tyres and their pressure as soon as possible.
● Under certain conditions (e.g. sporty driv-
ing styl
e, driving on loose surfaces or in win-
ter) the warning lamp  may take a while to
light up or may remain switched off.
● Despite the tyre pressure monitoring sys-
tem, the driver r
emains responsible for main-
taining the correct tyre pressure. You must
therefore check the tyre pressure often. Note
● The tyr e pr

essure monitoring system is not
a replacement for regularly checking the tyre
pressure, as it is unable to recognise an even
drop in pressure.
● The tyre pressure monitoring system is un-
able t
o warn of a sudden drop in tyre pres-
sure, e.g. a puncture. In this case, try to stop
the vehicle carefully with no severe braking
or steering manoeuvres.
● To ensure the tyre pressure monitoring sys-
tem work
s correctly, the basic setting must
be performed every 10 000 km (6000 miles)
or once a year.
● If the battery is disconnected the warning
lamp  lights

up when the ignition is switch-
ed on. This warning lamp must switch off af-
ter covering a short distance. 221
