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 all work on tyres and wheels carried out by an
authorised SEAT dealer.
● We recommend using wheels, tyres, hub caps and snow chains from the
SEAT Original Accessories programme. 
Tyre useful life
Fig. 124 Side view of
tyres with tread wear in-
dicators
Tread wear indicator
The base of the side of the original tyres on your vehicle show 1.6 mm high
tread wear indicators ⇒ Fig. 124. The position of these indicators is given
on the tyre sidewalls by the letters “TWI”, triangular symbols or other sym-
bols. The useful life of the tyres depends primarily on the following factors:
Tyre pressure values
Under-inflation or over-inflation will considerably reduce the useful life of
the tyres and impair the vehicle's handling. Therefore, check the tyre pres-
sure, including the spare wheel, at least once a month and before any long
journey.
Inflation pressures for
summer tyres are listed on a sticker inside the fuel
tank flap. The pressures for winter tyres are 20 kPa (0.2 bar) above the sum-
mer values.
Always check the pressure when the tyre is cold. Do not reduce over-pres-
sure in warm tyres. The tyre pressures must be altered to suit notable
changes in the load being carried.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Wheel balancing
The wheels on new vehicles are balanced. Various factors encountered
when driving can cause them to become unbalanced, which results in vibra-
tion of the steering wheel.
The wheel must be rebalanced if a new tyre is fitted or if a tyre is repaired.
Incorrect wheel alignment
Incorrect front or rear wheel alignment causes excessive tyre wear, frequent-
ly on one side, and also impairs vehicle safety. If tyre wear is very irregular,
contact an Official Service.
Tyre damage
To avoid damage to tyres and wheels, only drive over kerbs or similar obsta-
cles slowly and at a right angle if possible.
Check tyres and wheels regularly for damage (punctures, cracks, blisters,
deformities, etc.). Remove any foreign objects embedded in outside of the
treads. 

189
Wheels and tyres
Unusual vibration or the car pulling to one side may indicate that one of the
tyres is damaged. Reduce speed immediately and stop if you suspect that
damage may have occurred! Check the tyres for damage (blisters, cracks,
etc.). If no external damage is visible, drive slowly and carefully to the near-
est Official Service and have the vehicle inspected. 
Handling wheels and tyres
Fig. 125 Changing
wheels around
Changing wheels around
If the wear is visibly greater on the front tyres, they should be exchanged for
the rear tyres as shown in the diagram ⇒ Fig. 125. All the tyres will then last
for about the same time.
To ensure that the wear is equal on all tyres and maintain their optimum
useful life, they should be changed around every 10 000 km (6000 miles).
Storing tyres
Mark tyres when you remove them to indicate the direction of rotation. This
ensures you will be able to install them correctly when you replace them.
When removed, the wheels and/or tyres should be stored in a cool, dry and
preferably dark location. Store tyres in a vertical position if they are not fit-
ted on wheel rims. Replacing tyres and wheels
All four wheels must be fitted only with tyres of the same type, size and the
same tread pattern.
The correct tyre/wheel combinations specified for your vehicle are listed in
its registration documentation.
Understanding the tyre designations makes it easier to choose the correct
tyres. The tyre designation is marked on the sidewall. For example.

Wheels and tyres
Follow the instructions below when driving with this wheel fitted.
● After fitting the wheel, the warning sign must not be covered.
● Do not drive faster than 80 km/h (50 mph) with a spare wheel and take
great care during the trip. Avoid heavy acceleration, hard braking and fast
cornering.
● The tyre pressure is the same as that of the standard tyres.
● Only use this spare wheel to reach the nearest Official Service, as it is
not designed for permanent use.
WARNING
● Under no circumstances must damaged spare wheels be used.
● If the spare wheel is different in size or design to the tyres currently
fitted, never drive faster than 80 km/h (50 mph). Avoid heavy accelera-
tion, hard braking and fast cornering.
CAUTION
Follow the instructions given on the temporary spare wheel label.
Note
The tyre pressure of the spare wheel must always correspond to the highest
pressure prescribed for the model of vehicle in question. 
Wheel trim
Removing
– Place the hook from the vehicle tool kit on the reinforced edge
of the wheel trim. –
Insert the box spanner through the hook, supporting it on the
tyre and remove the wheel trim.
Fitting
– First press the wheel trim onto the wheel at the cut out de-
signed for the valve. Then press the wheel trim on both sides in
the direction of the valve so that it fits correctly in place around
all the perimeter.
CAUTION
● Press down by hand, do not hit the wheel trim! Knocking it sharply, par-
ticularly at points where the wheel trim has not yet been inserted, could re-
sult in damage to the wheel trim guiding and centring elements.
● Before fitting the trim on a steel alloy wheel attached with an anti-theft
wheel bolt, make sure the bolt is in the hole in the valve area ⇒ page 202,
Anti-theft wheel bolts.
● Where trim is fitted at a later date, ensure enough air inflow is guaran-
teed in order to cool the brake system. 

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. 

–Lower the vehicle.
– Tighten the wheel bolts firmly in diagonal sequence with the
box spanner and then the anti-theft wheel bolt ⇒ page 200.
– Replace the hub cap and/or the bolt covers.
Note
● All bolts must be clean and turn easily.
● Never grease or oil the wheel bolts!
● Note the direction of rotation when putting on a tyre with directional
tread pattern ⇒ page 187. 
After changing a wheel
Tasks that must be carried out after changing a wheel.
– Place the wheel with the defective tyre in the spare wheel well
and secure it using a special bolt ⇒ page 190.
– Put the vehicle tools back in their storage location.
– Check the tyre pressure of the newly fitted spare wheel as soon
as possible.
– Have the tightening torque of the wheel bolts checked as soon
as possible with a torque wrench.
– Have the flat tyre replaced or ask an Official Service about the
possibility of repair.
Note
● If you notice that the wheel bolts are rusty and difficult to turn when
changing a wheel, they must be replaced before having the tightening tor-
que checked.
● Drive carefully and at moderate speeds until the tightening torque of the
wheel bolts has been checked. 

Tyre repair kit* Introduction
The tyre repair kit is stored in a box under the carpet in the luggage com-
partment.
The tyre repair kit will reliably seal tyres damaged by foreign bodies, provi-
ded that cuts or punctures are no larger than approx. 4 mm in diameter. Do
not remove the foreign bodies, e.g. bolts or nails, from the tyre!
The tyre must be repaired immediately.
The repair made using the tyre repair kit under no circumstances replaces
permanent tyre repair and should only be used to drive to the nearest Offi-
cial Service.
The tyre repair kit must not be used:
● If the wheel rim has been damaged
● At outside temperatures below -20 °C (-4 °F)
● On cuts or punctures larger than 4 mm
● If the sidewall of the wheel has been damaged
● If you have been driving with very low tyre pressure or a completely flat
tyre
● If the best-before date on the air can has expired 

Self-help
WARNING
● If you have a puncture in moving traffic, switch on the hazard warning
lights and place the warning triangle at the obligatory distance. Observe
the applicable local legal regulations. This is for your own safety and that
of other road users.
● If you have a flat tyre, stop the vehicle well away from moving traffic.
Choose a location that is as level and solid as possible.
● A tyre filled with sealant does not have the same performance proper-
ties as a conventional tyre.
● Do not drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and fast cornering.
● Check the tyre pressure after 10 minutes of driving!
● The sealant is harmful to health and must be immediately rinsed from
affected skin.
For the sake of the environment
Used or out-of-date sealant must be disposed of in line with environmental
protection regulations.
Note
● Observe the instructions for use provided by the tyre repair kit manufac-
turer.
● A new can of sealant can be acquired from the selection of SEAT Original
Accessories.
● Change the tyre repaired using the tyre repair kit as soon as possible or
ask an Official Service about the possibility of repair. Tyre repair kit components
