Engine coolant Introduction WARNING
Engine coolant is toxic!
● Only keep engine coolant in its original
container, tightly shut and in a safe place.
● Never store engine coolant in empty food
containers or bottles as other people may ac-
cidentally drink it.
● Always keep engine coolant out of reach of
children.
● Ensure that the proportion of engine cool-
ant additive corresponds to the lowest out-
side temperature to which the vehicle will be
exposed.
● If the outside temperature is extremely low,
the engine coolant could freeze causing the
vehicle to stop. As this would also cause the
heating to stop working, vehicle occupants
without warm clothing could freeze. For the sake of the environment
Coolants and additives can contaminate the
environment. Collect any spilt fluids in suita-
ble containers and dispose of them in accord-
ance with legislation and with the utmost re-
spect for the environment. Coolant warning lamp

On the display of the Portable Navigation
System (supplied by SEAT) ››› page 123 an en-
gine coolant temperature gauge can be seen. Engine coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and, at least, 40 % of the additive
G 13
(TLVW 774 J). The engine coolant additive is
recognisable by its purple colour. This mix-
ture of water and additive gives the necessa-
ry frost protection down to -25°C (-13 F) and
protects the light alloy parts of the cooling
system against corrosion. It also prevents
scaling and considerably raises the boiling
point of the coolant.
To protect the engine cooling system, the
percentage of additive must always be at
l e

ast 40 %, even in warm climates where an-
ti-freeze protection is not required.
If greater frost protection is required in very
cold climates, the proportion of additive can
be increased. However, the percentage of ad-
ditive should not exceed 60%, as this would
150

Checking and refilling levels
reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture
of distilled water and, at least, 40 % of the G
13 or G 12 p lu
s-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› . The mixture of G
13 with G 12 plus (TL-VW 774 F), G 12 (red) or
G 11 (green-blue) engine coolants will signifi-
cantly reduce the anticorrosion protection
and should, therefore be avoided ››› .
WARNING
If there is not enough anti-freeze in the cool-
ant system, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additive is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the coolant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
The original additives should never be mixed
with coolants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system. ●
If the fluid in the expansion tank is not pur-
ple but is, for example, brown, this indicates
that the G 13 additive has been mixed with
an inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. For the sake of the environment
Coolants and additives can contaminate the
environment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Checking the engine coolant level and

Checking and refilling levels
In the course of time, the brake fluid absorbs
water from the ambient air. If there is too
much water in the brake fluid, the brake sys-
tem could be damaged. In addition, the boil-
ing point of the brake fluid is significantly
lowered. When the brake fluid contains too
much water and the brakes are subject to
considerable forces, bubbles of water vapour
can form in the system. These bubbles can
significantly reduce braking power, notably
increasing braking distance, and could even
result in the total failure of the brake system.
Ensuring that the brake system is always
functioning correctly is essential for your own
safety and the safety of other road users
››› .
Brake fluid specifications
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 br ak
e 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
››› .
Brake fluids 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 is 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-
ble/old 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 accordance with the instructions given
in the Maintenance Programme.
● When the brake fluid is used and brakes
are subjected to extreme braking forces, bub-
bles of vapour form in the brake system.
These bubbles can significantly reduce brak-
ing power, notably increasing braking dis-
tance, and could result in the total failure of
the brake system.
● Always ensure that you use suitable brake
fluid. Only used 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. WARNING
Brake fluid is poisonous. » 153

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.
