Practical tips

The engine comes with a special, multi-grade

oil that can be used all year round.

SEAT recommends changing the oil at a spe-

cialised workshop. SEAT recommends an Of-

ficial SEAT Service.

Engine oil

Because the use of high-quality oil is essen-

tial for the correct operation of the engine

and its long useful life, when topping up or

changing oil, use only those oils that comply

with VW standards.

General notes

SEAT recommends the use of engine oils ap-

proved according to the appropriate VW

standard. Use of engine oils that do not meet

these quality requirements can cause engine

damage.

For vehicles with an engine oil label

SEAT recommends the use of Original SEAT

Spare Part engine oils.

If the engine oil has to be topped up, use one

of the oils shown on the label Fig. 228. The

●

Never pour oil down drains or into the

ground.

WARNING

Only change the engine oil yourself if you

have the specialist knowledge required!

Yellow or colourless: The battery's electrolyte

level is too low. Go to a specialised work-

shop to have the battery checked and

replaced if necessary.

The 12-volt vehicle battery has been de-

signed to suit its location and has specific

safety features. If the battery needs to be re-

placed, it is recommended that it be installed

by an official SEAT qualified workshop. These

workshops have the technical documenta-

tion and equipment required to find out the

size, technology, and maintenance and safe-

ty requirements of the new battery.

Black: The battery’s electrolyte level is cor-

rect.

Charging or changing the battery

 Always use maintenance-free batteries

according to the TL82506 and VW75073

standards. These standards must be from

October 2014 or later.

If you often drive short distances or if the ve-

hicle is not driven for long periods, the 12-volt

battery should be checked by a specialised

workshop more frequently than the service

intervals.

battery (schematic representation).

The degassing tube must always be connec-

ted to the hole on the negative pole side and

the hole on the positive pole side must be

sealed.

The electrolyte level should be checked reg-

ularly in high-mileage vehicles, in hot coun-

tries and in older batteries.

If the battery has discharged and you have

problems starting the vehicle, the battery

might be damaged. If this happens, we rec-

ommend you have the vehicle battery

checked by a Technical Service where it will

be re-charged or replaced.

The vehicle’s 12V battery must always be re-

placed by a qualified specialist company, as

the vehicle’s electronics must be adapted

during replacement. In addition, the battery

parameters for functional safety have been

determined based on the original battery.

Only a qualified specialist company has the

right technology to fit the correct replace-

ment battery.

sufficient lighting to clearly identify the colour

shown in the battery window. Never use

flames or objects that burn without a flame

as a light source.

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 environ-

ment.

●

If there are air bubbles in the window, tap

the window gently until they disperse.

The “magic eye” indicator, located on the top

The power management function ensures

that the battery is charged much more effi-

ciently than on vehicles without a power

management system. To maintain this func-

tion after replacing the battery, we recom-

mend that the replacement battery used is of

the same make and type as the original fitted

battery. To make proper use of the power

management function after the battery has

been changed, have the battery coded to the

power management mode at a specialised

workshop.

In addition to a 12-volt battery, the vehicle

may be fitted with a 48-volt battery located

underneath the front passenger seat.

The works that are to be carried out on the

48 volt battery should be performed exclu-

sively by a specialised workshop with duly

qualified technical staff, trained according to

the SEAT guidelines.

Overview of the 48 volt system

The 48 volt system consists of the following

With the engine switched off

The residual current management reduces

power consumption while the vehicle is

parked. It controls the supply of power to the

various electrical devices while the ignition is

switched off. The system takes the battery di-

agnosis data into consideration.

For example, if you listen to the sound system

with the engine switched off the battery will

run down.

Flat battery

Starting ability has first priority.

If the energy consumption means there is a

risk that the engine will not start, a text will be

displayed in vehicles with a driver information

system.

Short trips, city traffic and low temperatures

all place a heavy load on the battery. In

these conditions a large amount of power is

consumed, but only a small amount is sup-

plied. The situation is also critical if electrical

devices are in use when the engine is not run-

ning. In this case power is consumed when

none is being generated.

Depending on the power level of the battery,

switch off the individual electrical devices

one after the other to prevent the battery

from losing too much charge and to ensure

that the engine can be started reliably.

This driver indicator tells you that you must

start the engine so that the battery can re-

charge.

Dynamic power management

When the engine is running

While the vehicle is moving, this function dis-

tributes the available power to the various

electrical devices and systems according to

their requirements. The power management

ensures that on-board systems do not con-

sume more electrical power than the alterna-

tor can supply, and thus maintains the maxi-

mum possible battery power level.

In these situations you will be aware that the

power management system is intervening to

control the distribution of electrical power.

Although the alternator generates electrical

power, the battery can still become dis-

charged while the vehicle is being driven. This

can occur when a lot of power is being con-

sumed but only a small amount supplied, es-

pecially if the battery is not fully charged ini-

tially.

When the vehicle is parked for long peri-

ods

If you do not drive your vehicle for a period of

several days or weeks, the power manage-

ment will gradually shut off the electrical de-

vices one by one or reduce the amount of

current they are using. This limits the amount

of power consumed and helps to ensure reli-

able starting even after a long period. Some

To restore the necessary energy balance, the

system will then temporarily shut off the elec-

trical devices that are using a lot of power, or

reduce the current they are consuming. Heat-

ing systems in particular use a large amount

of electrical power. If you notice, for instance,

Low profile tyres

Wheels

Low profile tyres have a wider tread, a larger

wheel diameter and a lower sidewall height.

Therefore, its driving behaviour is more agile.

Wheels and tyres

Low profile tyres may deteriorate more quick-

ly than standard tyres, for instance due to

strong knocks, potholes, manhole covers and

kerbs. Correct tyre pressure is very important

General notes

You may also notice that the engine runs at a

slightly faster idling speed when necessary.

This is quite normal, and no cause for con-

cern. The increased idling speed allows the

alternator to meet the greater power require-

ment and charge the battery at the same

time.

When driving with new tyres, be especially

careful during the first 500 km (300 miles).

If you have to drive over a kerb or similar

obstacle, drive very slowly and as near as

possible at a right angle to the obstacle.

To avoid damage to tyres and wheels, drive

with special care when driving on roads in

poor condition.

–

Check from time to time if the tyres are

damaged (punctures, cuts, cracks or

dents). Remove any foreign objects em-

bedded in the treads.

Visually check your wheels every 3000 km.

If the tyres or rims have received a heavy im-

pact or have been damaged, have a special-

ised workshop check whether or not it is nec-

essary to change the tyre.

–

Damaged wheels and tyres must be re-

placed immediately.

Low profile tyres may deteriorate more quick-

Concealed damage

–

Mark the wheels before taking them off so

that they rotate in the same direction when

put back.

Damage to tyres and rims is often not readily

visible. If you notice unusual vibration or the

car pulling to one side, this may indicate

that one of the tyres is damaged. Reduce

speed immediately if there is any reason to

suspect that damage may have occurred. In-

spect the tyres for damage. If no external

damage is visible, drive slowly and carefully

Keep your speed below 50 km/h (30 mph).

It is best to contact a SEAT Official Service to

check the maximum speed which is permissi-

ble for the V-rated tyres fitted on your car on

the basis of this information.

If there is a danger of being trapped de-

spite having fitted the chains, it is best to disa-

ble the traction control (TCS) in the ESC

ing the ESC and TCS.

WARNING

Snow chains will improve braking ability as

well as traction in winter conditions.

Exceeding the maximum speed permitted

for the winter tyres fitted on your car can

cause tyre failure, resulting in a loss of con-

trol of the vehicle – risk of accident.

WARNING

The use of unsuitable or incorrectly fitted

chains could lead to serious accidents and

damage.

For technical reasons snow chains may only

be used with the following wheel rim/tyre

combination.

●

Always the appropriate snow chains.

For the sake of the environment

Observe the fitting instructions provided

by the snow chain manufacturer.

When winter is over, change back to sum-

mer tyres at an appropriate moment. In

temperatures above +7°C (+45°F), perform-

ance will be improved if summer tyres are

used. Fuel consumption, wear and noises

while driving will all be reduced.

●

Never exceed the maximum permitted

speeds when driving with snow chains.

CAUTION

●

Remove the snow chains to drive on

roads without snow. Otherwise they will im-

pair vehicle handling, damage the tyres

and wear out very quickly.

Driving for the first time with new tyres at

a high speed can cause them to slightly ex-

pand, which could then produce an air

pressure warning.

When driving, the system self-calibrates the

tyre pressure provided by the driver and the

wheels fitted. After a long journey with varied

speeds the programmed values are collected

and monitored.

●

If excessively low tyre pressure is detec-

ted with the ignition on, an audible warning

will sound. In the event that there is a fault

in the system, an audible warning will

With the wheels under very heavy loads, the

tyre pressure must be increased to the total

lamp shows a fault, but disappears when

road conditions or the driving style change.

WARNING

When the tyres are inflated at different

pressures or at a pressure that is too low

then a tyre may be damaged resulting in a

loss of control of the vehicle and a serious

or fatal accident.

●

Do not only rely on the tyre pressure

monitoring system. Regularly check your

tyres to ensure that the tyre pressure is cor-

rect and that the tyres are not damaged

due to puncture, cuts, tears and im-

pacts/dents. Remove objects from the

tyres only when they have not pierced the

tyres.

●

If the lamp  lights up, reduce speed im-

mediately and avoid any sudden turning or

braking manoeuvre. Stop when possible,

and check the tyre pressure and status.

●

The tyre pressure monitoring indicator

does not function when there is a fault in

the ESC or ABS page 275.

●

The tyre pressure monitoring system can

only operate correctly if all of the tyres are

inflated to the correct pressure when cold.
