WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
● Always observe any lit warning lamps and text messages.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle.
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted 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 necessary 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 al-
ways be at least 40 %, even in warm climates where anti-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 additive should not
exceed 60 %, as this would 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 plus-plus (TL-VW 774 G) additive (both are purple) to obtain an optimum anticorrosion 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 significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒
.
WARNING
If there is not enough anti-freeze in the coolant system, the engine may
fail leading to serious damage.
● Please make sure that the percentage of additive is correct with re-
spect 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 heating 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 purple but is, for example,
brown, this indicates that the G 13 additive has been mixed with an inade-
quate 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.

If the coolant level is low, the coolant warning indicator will light. Preparations
●
Park the vehicle on even, flat and firm ground.
● Allow the engine to cool ⇒
.
● Open the bonnet ⇒ page 279.
● The coolant expansion tank is easily recognisable because of the sym-
bol on the cap ⇒ Fig. 175.
Checking the engine coolant level
● When the engine is cold, check the coolant level using the side marking
on the expansion tank ⇒ Fig. 174.
● If the level is below the “MIN” mark, top up with coolant. When the en-
gine 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 coolant and steam
using a large, thick cloth over the coolant expansion tank cap.
● Remove the cap very carefully ⇒
.
● Only refill using new engine coolant according to SEAT specifications
(⇒ page 289) ⇒
.
● The engine coolant level should be between the marks on the coolant
expansion tank ⇒ Fig. 174. Do not exceed the top level of the marked area
⇒
.
● Screw on the cap tightly.
● If, the event of an emergency, you have no coolant that is compliant to
the required specifications ( ⇒ page 289), never use another type of addi-
tive. Instead, first top up with distilled water ⇒
only. Then re-establish
the correct proportion of the mixture with the correct additive as soon as
possible ⇒ page 289.

WARNING (Continued)
● Battery acid is very corrosive and caustic. It can burn skin and cause
blindness. When handling the battery, protect yourself from splashes of
acids, above all your hands, arms and face.
● Never tilt the vehicle battery. Battery acid could spill out of the open-
ings to release gases and cause corrosion damage.
● Never open the vehicle battery.
● If battery acid splashes on you, immediately rinse your eyes and skin
abundantly with water for several minutes. Then seek medical care imme-
diately.
● If acid is swallowed by mistake, consult a doctor immediately.
Charging, replacing and connecting or disconnecting the
battery
Charging the battery
The vehicle battery should be charged by a specialised workshop only, as
batteries using special technology have been installed and they must be
charged in a controlled environment ⇒
. SEAT recommends visiting a
Technical Service.
Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and
has special safety features. If the battery must be replaced, consult a Tech-
nical Service for information on electromagnetic compatibility, the size and
maintenance, performance and safety requirements of the new battery in
your vehicle before you purchase one. SEAT recommends you have the bat-
tery replaced by a Technical Service.
Use only maintenance-free genuine batteries conforming to TL 825 06 and
VW 7 50 73 Standards. These standards must be dated April 2008 or later. Start-Stop systems (
⇒ page 198) are equipped with a special battery. There-
fore, it must only be replaced with a battery of the same specifications.
Disconnecting the vehicle's battery
If you must disconnect the battery from the electrical system, please note
the following:
● Switch off the ignition and all electrical equipment.
● The vehicle must be unlocked before disconnecting the battery, other-
wise the alarm will be triggered.
● First disconnect the negative cable and then the positive ⇒
.
Connecting the vehicle's battery
● Before reconnecting the battery, switch off the engine, the ignition and
electric devices.
● First reconnect the positive cable and then the negative ⇒
.
Different control lamps may light up after connecting the battery and switch-
ing the ignition on. They will be turned off after a short trip at a speed of
between 15-20 km/h (10-12 mph). If the warning indicators remain lit,
please visit a specialised workshop to have the vehicle checked.
If the battery has been disconnected for a long time, it is possible that the
next service date is not displayed or calculated correctly ⇒ page 57. Respect
the maximum service intervals permitted ⇒ Booklet Maintenance Pro-
gramme.
Automatic consumer disconnection
The intelligent vehicle electrical system automatically implements a range
of measures to prevent the battery from discharging when high demands
are made on it:
Safety FirstOperating instructionsPractical TipsTechnical Specifications

296Checking and refilling levels
● the idling speed is increased so that the alternator provides more elec-
tricity.
● where necessary, the power of the most powerful consumers is reduced
or even completely disconnected.
● On starting the engine, the power supply from the 12-volt power sockets
and the cigarette 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 does the battery run flat?
● When stationary for a long time without starting the engine, particularly
if the ignition is switched on.
● Use of electrical consumers with the engine switched off.
● If the auxiliary heater is running ⇒ page 165.
WARNING
Incorrectly securing the battery or using the wrong battery can cause
short-circuits, fire and serious injuries.
● Always use only maintenance free batteries that do not run flat alone
and whose properties, specifications and size correspond to the stand-
ard battery. The specifications are indicated on the battery case.
WARNING
A highly explosive mixture of gases is released 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 al-
so freeze at temperatures close to 0 °C (+32 °F).
WARNING (Continued)
● Always replace a battery which has frozen.
● Battery cables not correctly connected may cause a short circuit. Re-
connect first the positive cable and then the negative cable.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● Never plug accessories supply current, such as solar panels or a battery
charger, to the 12-volt power sockets or the cigarette lighter. This could
damage the vehicle's electrical system.
For the sake of the environment
● Dispose of the battery in an environment-friendly manner. Batteries con-
tain toxic substances such as sulphuric acid and lead.
● Battery acid can contaminate the environment. Collect any spilt service
fluids and allow a dispose of them correctly.

310Wheels and tyres
Changing a wheel*
Introduction
The tyres mounted on the vehicle are anti-puncture. The wheels should only
be changed when switching from summer to winter tyres or vice-versa. See
⇒ page 303
You should only change the wheels yourself if the vehicle is parked in a safe
place, you are familiar with the procedure and you have all the necessary
tools! Otherwise, you should seek professional assistance.
Additional information and warnings:
● Vehicle key set ⇒ page 72
● Wheels and tyres ⇒ page 297
● Wheel trims ⇒ page 308
● Vehicle tools ⇒ page 324
WARNING
Changing a wheel can be dangerous, especially on the hard shoulder.
Please observe the following rules to minimise the risk of injury:
● Stop the vehicle safely as soon as possible. Park your vehicle as safe
distance from surrounding traffic to change a wheel.
● When changing a wheel, keep all passengers and particularly chil-
dren a safe distance away from the work area.
● Turn on the hazard warning lights to warn other road users.
● Ensure the ground on which you park is flat and solid. If necessary,
support the jack on a wide solid base.
● If you are changing a wheel yourself, you should be familiar with the
required procedure. Otherwise, you should seek professional assistance.
WARNING (Continued)
● Only use suitable tools that are not damaged when changing a wheel.
● Always stop the engine, turn on the electronic parking brake and
place the gear selector lever in position P, for an automatic gearbox, or
engage a gear for a manual gearbox to reduce the risk of the vehicle mov-
ing accidentally.
● Have the tightening torque of the wheel bolts checked as soon as
possible with a reliable torque wrench.
