Coolant
General notes
The cooling system is factory-filled with an anti-freeze product.
Coolant consists of a mixture of water and 40% anti-freeze additive. This
mixture gives the required anti-freeze protection at temperatures down to
-25 °C (-13 °F) and protects the cooling and heating system against corro-
sion. It also prevents scaling and raises the boiling point of the coolant con-
siderably.
The coolant concentration must not be reduced by adding water, even in
warmer seasons or in warm countries. The concentration of the anti-freeze
additive in the coolant must be at least 40 %.
If greater anti-freeze protection is required in very cold climates, the propor-
tion of the anti-freeze additive can be increased, but only up to 60 % (anti-
freeze protection down to approx. -40 °C (-40 °F)). Any excess in this propor-
tion would reduce the anti-freeze protection and affect the cooling effect.
Vehicles in countries with a cold climate are supplied with coolant protec-
tion down to around -35 °C (-31 °F). The proportion of anti-freeze additive in
these countries should always be at least 50 %.
The type of anti-freeze to be used for topping up is indicated on the coolant
tank cover ⇒ Fig. 119.

CAUTION
● Anti-freeze that does not correspond to the correct specification may
particularly affect corrosion protection considerably.
● Faults caused by corrosion may lead to coolant leaks. Risk of serious en-
gine faults! 

B
(min.) and A (max.). When the engine is hot, it may be
slightly above mark A (max.).
The warning lamp  (red) in the general instrument panel ⇒ page 68, Cool-
ant level and temperature  will appear when the coolant level is too low.
However, we recommend checking the coolant level directly in the tank.
Coolant loss
Any loss of coolant normally indicates a leak. It is not sufficient merely to
top up the coolant. The cooling system should be inspected by an Official
Service without delay.
CAUTION
In the event of a fault that causes the engine to overheat, contact an author-
ised SEAT dealer immediately, as this could damage the engine. 
Topping up coolant
– Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion tank ⇒ Fig. 119 with a
cloth and carefully unscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into place.
Do not use a different type of additive if the prescribed anti-freeze additive
is not available, in the event of an emergency. In this case, use only water
and bring the coolant concentration back up to the correct level as soon as
possible at an Official Service. Always top up with unused coolant.
Never fill the coolant tank above mark
A
(max.) ⇒ Fig. 119 Excess coolant
is forced out of the cooling system through the overpressure valve in the fill-
er cap of the expansion tank when the engine heats up.
WARNING
● The anti-freeze additive and, therefore, the entire coolant, are a
health hazard. Avoid touching the coolant. Coolant fumes are also a
health hazard. Store the coolant additive in a safe place out of the reach
of children. Risk of poisoning!
● If splashed into eyes, rinse immediately with clean water and seek
immediate medical advice.
● Seek immediate medical advice if the coolant is accidentally inges-
ted.
CAUTION
If the engine oil cannot be topped up under the given conditions,  do not
drive on. We recommend contacting an authorised SEAT dealer, as this can
damage the engine. 
Radiator fan
The radiator is driven by an electric motor and controlled according to the
temperature of the coolant.
After the engine has been stopped and the ignition switched off, the radia-
tor fan may continue running for around 10 minutes. 

Checking and refilling levels
Brake fluid Checking brake fluid level
Fig. 120 Engine com-
partment: Brake fluid res-
ervoir
The brake fluid reservoir is located in the engine compartment of
the vehicle.
– Switch the ignition off.
– Open the bonnet ⇒ page 173.
– Check the brake fluid level in the reservoir ⇒ Fig. 120. It should
be between the “MIN” and “MAX” marks.
The fluid level drops slightly after a period of time due to automatic com-
pensation 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 in
the instrument panel 
⇒  page 66, Brake system .
WARNING
If the fluid level has dropped below the MIN mark,  do not drive on.
Risk of accident! Seek professional help.

Changing brake fluid
Brake fluid absorbs moisture. Therefore, it gradually absorbs moisture from
the atmosphere. 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 specifi-
cations:
● VW 50114
● FMVSS 116 DOT4
WARNING
Heavy use of the brakes may cause a vapour lock if the brake fluid is left
in the brake system for too long. This would seriously affect the efficien-
cy of the brakes and the safety of the vehicle.
CAUTION
Brake fluid damages the vehicle paintwork. 

Checking and refilling levels
Incorrect handling of the vehicle battery could lead to damage. We therefore
recommend all work on the vehicle battery be performed 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 electrical system.
Therefore, always observe the warnings and follow all general safety pre-
cautions.
WARNING
● Battery 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 and causes deep, difficult-to-heal wounds when in contact with
the skin. Repeated contact with diluted acids causes skin disease (in-
flammation, 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. Pro-
tect 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 with soap solu-
tion as quickly as possible and rinse off with plenty of water. If acid is
swallowed by mistake, consult a doctor immediately.
● Keep children away from the battery.
● Hydrogen is released and a highly explosive mixture of gases is gen-
erated when the battery is under charge. Sparks when disconnecting or
releasing cable terminals with the ignition switched on could also cause
an explosion.
● A short circuit is produced if the battery terminals are bridged, e.g.
using metal objects, cables, etc. Possible consequences of a short cir-
cuit: melting of lead plates, battery explosion and fire, splashing acid.
WARNING (Continued)
● The following is forbidden while working on the battery: 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 must switch off the en-
gine, 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 battery. Risk of explosion and
acid burns! Replace a frozen battery.
● Never use the jump leads on batteries in which the electrolyte level is
too low. Risk of explosion and acid burns.
● Never use a damaged battery. Risk of explosion! Replace a damaged
battery immediately.
CAUTION
● Never disconnect the battery when the ignition is switched on, as the
electrical system (electronic components) of the vehicle could be damaged.
When disconnecting the battery from the vehicle electrical system, discon-
nect its negative terminal (-) first. Only then may the positive terminal (+) be
disconnected.
● When connecting the battery, connect the positive terminal (+) first. On-
ly then may the negative terminal (-) be connected. The battery cables must
never be connected to the wrong battery terminals. Risk of burning the elec-
trical installation.
● Make sure the battery acid does not come into contact with the body-
work. Risk of paintwork damage.
● Do not expose the battery to direct sunlight to protect it from ultraviolet
radiation. 

Checking and refilling levels
Note
● The battery acid level is also regularly checked during servicing at au-
thorised SEAT dealers.
● The acid level on “AGM” vehicle batteries cannot be checked for techni-
cal reasons.
● Vehicles equipped with the “START-STOP” system include a battery con-
trol unit to control the battery level for repeat engine starting. 
Winter service
At low temperatures the battery provides only a fraction of the starting pow-
er it has at normal temperatures.
A flat battery can also freeze at temperatures slightly below to 0 °C (32 °F).
We therefore recommend you have the battery 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 reliable starting.
– Switch off the ignition and all electrical equipment.
– For “fast-charging” only: disconnect both battery connection ca-
bles (first the “negative” terminal and then the “positive”).
– Connect the charger cables to the battery terminals (red = “pos-
itive”, black = “negative”).
– Plug in the battery charger and switch on. –
After charging the battery: Switch off the battery charger and
disconnect the cable.
– Remove the charger cables.
– If necessary, reconnect both battery cables to the battery (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 have to be disconnected. The instructions of the battery
charger manufacturer must be followed.
Use a current equivalent to or lower than 0.1 of the battery capacity to fully
charge the battery.
Before “fast-charging” the battery however, both battery cables must be
disconnected.
“Fast-charging” a battery is dangerous and requires a battery charger and
special knowledge. Fast charges should be performed by an official techni-
cal service.
The battery caps should not be opened while the battery is being charged.
CAUTION
In vehicles fitted with the “START-STOP” system, the charger cable cannot
be directly connected to the negative terminal of the vehicle battery but
must be attached to the engine earthing point ⇒ page 207. 
Disconnecting and connecting the battery
The following functions will either be inoperative or will not work properly
after disconnecting and reconnecting the battery: 

Note
We recommend having the vehicle checked by an authorised SEAT dealer to
guarantee the correct working order of all electrical systems. 
Changing the battery
A replacement battery must have the same capacity, voltage, current rating
and size as the original. The appropriate types of battery can be acquired
from authorised SEAT dealers.
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 programme selected by the electrical
system control unit prevents the battery from automatically discharging.
This may result in the following:
● Increase in idling speed so that the alternator can supply more current
to the electrical system.
● The performance of certain electrical components could be limited or
some may switch off temporarily, e.g. the heated seats, the heated rear win-
dow, the 12V power socket.
Note
Despite any measures taken by the control unit, the battery could drain. e.g.
with the engine is switched off, the key is turned in the ignition for a long
period or the side lights or parking lights are switched on. The switching off
of certain electrical components does not impair driving comfort and the
driver will often not even realise. 

192Wheels and tyres
Removing
–Insert the plastic clip into the cap until the inner retaining
notches on the clips touch the collar of the cap and then re-
move ⇒ Fig. 127.
Fitting
– Insert the caps as far as they will go over the wheel bolts.
The wheel bolt caps are stored in a box on the spare wheel or in the spare
wheel well. 
Tyre pressure
Fig. 128 Tyre pressure
setting switch
The tyre pressure monitoring system uses ABS sensors to compare the revo-
lutions and the circumference of each wheel. Should the circumference of
any wheel change, the warning lamp  in the general instrument panel
⇒ page 72 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 trail-
er, uphill, downhill)
● Snow chains are fitted
● The temporary spare wheel is fitted
● One wheel on the axle 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 driving, the
system must be adjusted as follows:
● Inflate all tyres to the prescribed pressures ⇒ page 188.
● Switch the ignition on.
● Hold the  
⇒ Fig. 128 button down for at least 2 seconds. The warn-
ing lamp  will light up when the button is pressed. The system memory is
also deleted and a new calibration system will begin, which is indicated by
an audible warning before the warning lamp switches off .
● If the warning lamp  remains lit and does not switch off, not even once
the basic setting process is complete, this indicates a fault in the system.
Contact an Official Service.
The warning lamp  lights up
If the pressure on at least one tyre is significantly lower than the pressure
set by the driver, the warning lamp  ⇒ 
will light up.
The warning lamp  flashes
If the warning lamp flashes, there is a fault in the system. Contact a special-
ised service to have it fixed. 

Self-help
WARNING (Continued)
● Always raise the vehicle with the doors closed.
● Never place parts of your body, e.g. arms and legs, underneath the
vehicle when supported only by the jack.
● Secure the base of the jack with suitable supports so that it cannot
slip. The jack could slide if the ground below it is soft and slippery and
the vehicle could slip off it. Therefore, place the jack on a firm surface or
use a large, stable base. On a slippery surface, e.g. tiles, use a non-slip
base such as a rubber mat.
● Never start the engine when the vehicle is raised. Risk of injury.
● The jack should only be used in the correct jacking points.
CAUTION
● The prescribed tightening torque for wheel bolts on steel and alloy
wheels is 120 Nm.
● If the anti-theft wheel bolt is overly tightened, this could damage the
bolt and the adapter
Note
● The set of anti-theft wheel bolts or the adapter are available from au-
thorised SEAT dealers.
● Please observe the relevant local legal regulations when changing the
wheel. 
Preparation work
Some preparation is required before changing a wheel:
– If you have a flat tyre, stop the vehicle as far away as possible
from moving traffic. The surface must be horizontal.–
All vehicle occupants should leave the vehicle . Vehicle occu-
pants should waiting in a safe place, e.g. behind the roadside
crash barrier) while the wheel is being changed.
– Switch off the ignition and engage neutral or move the selector
lever on the automatic gearbox to position P.
– Apply the handbrake firmly.
– If towing a trailer, unhitch it.
– Take the vehicle tool kit ⇒ page 198 and the spare wheel
⇒ page 198 out of the luggage compartment. 
Changing a wheel
If possible, change the wheel on a level surface.
– Pull off the hub cap ⇒ page 191 or the wheel bolt covers
⇒ page 191.
– First loosen the anti-theft wheel bolts and then the other wheel
bolts ⇒ page 200.
– Raise the vehicle until the wheel to be changed is no longer
touching the ground ⇒ page 201.
– Remove the wheel bolts and place them on a clean surface
(cloth, paper, etc.).
– Take off the wheel.
– Lift the spare wheel into position and tighten the wheel bolts
lightly. 
