Checking the engine coolant level ● When the engine is cold, check the coolant
level
using the side marking on the expan-
sion tank ››› Fig. 170.
● If the level is below the “MIN” mark, top up
with coo
lant. When the engine is hot it may
be slightly above the marked area.
Topping up the engine coolant level
● Always protect your face, hands and arms
from hot c
oolant and steam using a large,
thick cloth over the coolant expansion tank
cap.
● Remove the cap very carefully ›››
.
● Only refill using new engine c
oo
lant ac-
cording to SEAT specifications
( ›››
 page 32)
››› .
● The engine coolant level should be be-
tw een the m
ark

s on the coolant expansion
tank ››› Fig. 170. Do not exceed the top level
of the marked area ››› .
● Screw on the cap tightly. ●
If, in the ev
ent

of an emergency, you have
no coolant that is compliant to the required
specifications ( ›››
 page 32), do not use
another type of additive. Instead, top up with
distilled water only ››› . Then re-establish
the c orr
ect

proportion of the mixture with the
correct additive as soon as possible
›››  page 32. WARNING
Hot vapours and coolant can cause serious
burn s.
● Nev

er open the coolant expansion tank if
ste
am or coolant is coming from the engine
compartment. Wait until you cannot see or
hear any steam or coolant escaping.
● Always wait until the engine has complete-
ly coo
led before very carefully opening the
expansion tank cap. Contact with hot ele-
ments of the engine can cause skin burns.
● When the engine is warm or hot, the cool-
ing sys
tem is pressurised. Do not unscrew
the cap on the expansion tank when the en-
gine is hot. Otherwise, coolant may spray out
under pressure causing burns and serious in-
jury.
– Carefully and slowly unscrew the cap an-
ti-clockwise, gently pressing down on it.
– Always protect your face, hands and arms
from hot coolant and steam using a large,
thick cloth. » 193

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 shou

ld 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 brake fluid should be changed regular-
ly in acc
ordance 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 br ak

e fluid is left in the system for
too long and the brakes 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.
W ipe off an

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

Checking and refilling levels
Automatic device disconnection
The int el
lig
ent 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 parking 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. 199

If you notice unusual vibration or the car pulls
to one s ide whi

le driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
obser
ving the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Reque
st qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly

on The tyre control lamp compares wheel revolu-
tion
s
and w

ith 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 wheel

s of one axle are under more
pres
sure (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.
Tyr
e pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 176 button must
be kept 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. The tyre pressure control lamp
 lights up
If
the tyre 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 tyr e pr

essure 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 s
porty 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
warnin g l

amp  lights up after turning the
ignition on. This should turn off after a brief
journey. 206
