Introduction

Release the bonnet stay and replace it in its

support.

All ﬂuids and consumables, such as engine

coolant or vehicle batteries, are subject to con-

tinuous development. For this reason, whenever

a ﬂuid or consumable needs to be replaced,

please contact a specialist workshop.

mentioned above.

Leakages of operating ﬂuids can contami-

nate the environment. If any operating ﬂuid

leaks, collect it in an appropriate container

and dispose of it properly and in an environ-

mentally friendly manner.

SEAT dealers always promptly receive informa-

tion about any modiﬁcations.

WARNING

Make sure that the bonnet is properly closed.

If it opens when driving, it can cause an acci-

dent.

If unsuitable ﬂuids and consumables are

used or used improperly, accidents, injuries,

burns and severe poisoning can occur.

Checking and reﬁlling levels

Get information from a specialist workshop

about which coolant is suitable for your vehicle.

SEAT recommends visiting a SEAT dealership

for this.

WARNING

Engine coolant is toxic!

If the vehicle’s cooling system does not have

sucient antifreeze protection, the engine

could fail and this could result in serious in-

jury.

●

Only store coolant in its original container,

tightly closed and in a safe place.

To protect the engine cooling system, the ad-

ditive percentage should always be at least

40%. If more antifreeze protection is required

for climatic reasons, the additive proportion

can be increased. However, it should only be

increased up to a maximum of 55 %, otherwise

the antifreeze protection would be reduced and

the cooling eect would be impaired.

●

Never store motor coolant in empty food

centage is correct, taking into account the

lowest ambient temperature expected in the

location where the vehicle is to be used.

The G12evo (TL-VW 774 L) can be recognised

by its lilac colouring. This mixture of water

and additive not only provides antifreeze pro-

tection down to -25°C (-13°F), but also pro-

tects the light alloy parts of the cooling system

against corrosion, prevents limescale build-up

and considerably raises the boiling point of the

coolant.

●

When the outside temperature is very low,

the coolant could freeze and the vehicle

could be immobilised. In this case, the heat-

ing would not work either and inadequately

dressed passengers could die of cold.

NOTICE

Never mix the original additives for the

G12evo coolant (TL-VW 774 L) with motor

coolant ﬂuid not authorised by SEAT.

When topping up the coolant, a mixture of dis-

tilled water and at least 40% of the appropri-

ate coolant additive should be used for opti-

mum corrosion protection ››› page 271.

NOTICE

●

All year round, G 052 164 A2 for clear glass.

Never mix an unsuitable antifreeze or other

similar additives with the windscreen washer

water. A greasy layer may be formed on the

windscreen which will impair visibility.

General notes

Approximate proportion of the winter mixture,

up to -18°C (0°F): 1:2 (1 part concentrate per

2 parts water); otherwise, a 1:4 proportion of

mixture in the washer ﬂuid tank.

●

Use clean water with a window cleaner

Residual current management system

Discharged battery

Energy management

The residual current management reduces en-

ergy consumption while the vehicle is station-

ary. When the ignition is switched o, it man-

ages the power supply to the various electrical

devices. In doing so, it takes into account the

battery diagnostic data.

Maintaining starting capacity has top priority.

Battery strain is considerable on short journeys,

city driving and in the cold season of the year.

Optimisation of the starting capacity

Energy management controls the electrical

power distribution so that there is always

enough electrical power to start the engine.

In these situations, a lot of energy is required

but very little is generated. If the engine is stop-

ped and at the same time the electrical devices

are switched on, the battery can become dis-

charged to a critical point. In this case energy

is consumed without being generated at the

same time.

If a vehicle with a conventional energy system

remains stationary for a long period of time, the

electrical devices, for example in the electronic

ignition lock, discharge the battery. Under cer-

tain circumstances, this can lead to a lack of

electrical power to start the engine.

Depending on the battery's charge level, it dis-

connects electrical devices one after the other

to avoid over-discharging the battery and to

maintain starting capacity.

In these situations you will notice that the en-

ergy regulation system performs active energy

distribution adjustment.

Dynamic energy management system

In your vehicle, a smart energy management

system is responsible for distributing the electri-

cal energy. This clearly improves the starting

performance and service life of the battery.

Energy generated while driving is distributed

by the dynamic energy management system

to the electrical devices according to their en-

ergy requirements. It also ensures that no more

energy is consumed than is generated, thus en-

suring an optimal battery charge level.

Vehicle stationary for a long period of time

If you do not drive the vehicle for a few days

or weeks, adjustments will be made to reduce

consumption or the electrical devices will be

deactivated one by one. This reduces energy

consumption and the starting capacity is main-

tained for longer. Some comfort functions may

not be available under certain circumstances.

The comfort functions will be available again

when the ignition is switched on and the engine

is started.

The main functions incorporated in the power

management system are battery diagnosis,

residual current management and a dy-

namic power management system.

Note

●

The energy management system also can-

Battery diagnostics

not override the limits imposed by the laws

of physics. Please note that the capacity and

service life of the battery are limited.

Battery diagnostics determine the status of the

battery on an ongoing basis. The battery volt-

age, current and temperature are monitored for

this purpose. This is used to determine the bat-

tery's charge level and eciency.

●

When there is a risk that the vehicle will not

start, the alternator power failure or low bat-

tery charge level warning lamp will be shown

››› page 281.

With the engine stopped

If you listen to the radio, for example, while

the engine is stopped, the battery will be dis-

charged.

282

CheEcnkeinrgyamndanreaﬁglelimngelnetvels

If the energy consumption means there is a risk

that the engine will not start, a text will be dis-

played in vehicles with a driver information sys-

tem.

This driver message indicates that the engine

must be started to recharge the battery.

With the engine running

The battery may discharge despite the fact

that energy is being generated while the vehi-

cle is in motion. This is particularly the case if

too little energy is generated and too much is

consumed at a time while the battery's level of

charge is not optimal.

To restore the energy balance, the devices that

consume the most energy are either tempora-

rily adjusted or deactivated. Heating systems,

in particular, consume a lot of energy. If you

notice, for instance, that the seat heating or the

rear window heater is not working, they may

have been temporarily switched o or regula-

ted to a lower heat output. These systems can

be used again as soon as the energy balance

has been restored.

If necessary, you may also notice a slight

idling speed boost. However, this is normal and

should not cause you any concern. Boosting

the idling speed generates additional energy

and charges the battery.
