When work in
g underneath the vehicle, se-
cure it so that it cannot roll away and support
it safely on suitable supports. The hydraulic
jack is not sufficient for this purpose. Risk of
injuries!
● If any tests have to be performed with the
engine runnin
g, there is an extra safety risk
from rotating parts, such as the drive belt, al-
ternator and radiator fan, etc., and from the
high-voltage ignition system. You should also
note the following:
– Never touch the electrical wiring of the
ignition system.
– Keep away from moving engine parts
when wearing jewellery, loose clothing or
long hair. Risk of fatal injuries! All jewel- lery must be removed, hair tied back and
close-fitting clothing worn.
● Observe the following additional warnings
if work
on the fuel system or the electrical
system is necessary.
–Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
● When top pin

g up fluids, make sure the cor-
rect fluid is put into the correct filler opening. Otherwise this can cause serious malfunc-
tions
or en

gine damage!
● Never open the bonnet using the release
catc
h. Risk of damage! For the sake of the environment
Due to the environmentally-friendly disposal
of fluid s, the equipment

necessary and the
knowledge required, let an authorised SEAT
dealer change fluids during service inspec-
tions of the vehicle. Note

The layout of the engine compartment is very
simi l

ar to all petrol and diesel engines. Radiator fan
The radiator is driven by an electric motor
and c
ontr
o

lled according to the temperature
of the coolant.
After the engine has been stopped and the
ignition switched off, the radiator fan may
continue running for around 10 minutes. Engine oil
General
notes The engine comes with a special, multi-grade
oil
th

at can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.

therefore recommend using clean water with
a gl a
s
s cleaning product to eliminate any
stubborn dirt (with an anti-freeze additive in
winter).
Although your vehicle has heated windscreen
washer jets, anti-freeze should always be
added to the water in winter.
Ethanol can be used where glass cleaner with
anti-freeze is unavailable. The concentration
of ethanol must be no greater than 15 %.
However, remember that anti-freeze in this
proportion only protects down to -5°C
(+23°F). CAUTION
● Never mi x

the windscreen washing water
with anti-freeze used for the cooling system
or other additives.
● If the vehicle is equipped with a headlight
washer sy
stem, only mix in with the water a
detergent that does not damage polycarbon-
ates. Note
When topping up the fluid, do not move the
filt er fr

om the container opening, as this
could contaminate the fluid hoses and lead to
a windscreen washer malfunction. Battery

and lit cigarettes away when working on the
battery!

A highly explosive mixture of gases is released
when the battery is under charge!

Keep children away from the battery!
Incorrect handling of the vehicle battery
c
ou
l

d lead to damage. We therefore recom-
mend all work on the vehicle battery be per-
formed by an authorised SEAT dealer.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working on the battery and the electri-
cal system. Therefore, always observe the
warnings and follow all general safety pre-
cautions. WARNING
● Batt er

y acid is very corrosive, therefore, the
battery must be handled with the utmost
care. Wear protective gloves and protect your
eyes and skin when handling batteries. The
corrosive fumes in the air irritate and inflame
the respiratory tract and cause conjunctivitis.
It corrodes tooth enamel. Causes deep and
difficult-to-heal wounds when it comes in
contact with the skin. Repeated contact with
diluted acids causes skin disease (inflamma-
tion, ulcers and fissures). When in contact
with water, acids dilute and develop a great
deal of heat.
● Do not tilt the battery, as acid could leak
out of the
vapour vents. Protect your eyes
with glasses or a protective helmet! Risk of
blindness! If acid should splash into the
eyes, rinse the affected eye immediately for
several minutes using clean water. Then seek
medical care immediately.
● Neutralize any acid splashes on the skin or
clothing w
ith soap solution as quickly as pos-
sible and rinse off with plenty of water. If acid
is swallowed by mistake, consult a doctor im-
mediately.
● Keep children away from the battery.
● Hydrogen is released and a highly explo-
sive mi
xture of gases is generated when the
battery is under charge. Sparks when discon-
necting or releasing cable terminals with the
ignition switched on could also cause an ex-
plosion. » 213

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

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
›››
page 218.
● Switch the ignition on.
● Store the new tyre pressure in the Easy
Connect sy
stem with the  button and the
S ET
TINGS function button
››
›

 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
