WARNING (Continued)
● Fires, sparks, open flames and smoking are prohibited. When han-
dling cables and electrical equipment, avoid causing sparks and electro-
static charge. Never short the battery terminals. High-energy sparks can
cause injury.
● 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.
● Keep children away from acid and batteries.
● Before working on the electrical system, you must switch off the en-
gine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only
switch off the light.
● Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
● When disconnecting the battery from the vehicle on-board network,
disconnect first the negative cable and then the positive cable.
● Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never re-
verse the polarity of the connections. This could cause an electrical fire.
● Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0°C.
● Ensure that the vent hose is always connected to the battery.
● Never use a defective battery. This could cause an explosion. Replace
a damaged battery immediately.
● For vehicles with the battery in the luggage compartment: Check that
the battery gas ventilation hose is securely attached.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.
● Do not expose the battery to direct sunlight over a long period of time,
as the intense ultraviolet radiation can damage the battery housing.
● If the vehicle is left standing in cold conditions for a long period, protect
the battery from freezing. If it freezes it will be damaged. 
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries. – Open the engine bonnet and the battery cover ⇒ 
in Safety in-
structions on working in the engine compartment on page 194
⇒ 
in Warnings on handling the battery on page 207. For vehi-
cles with the battery under the spare wheel, open the rear lid
and lift the floor covering. The battery is located next to the
spare wheel.
– Check the colour display in the "magic eye" on the top of the
battery.
– If there are air bubbles in the window, tap the window gently
until they disperse.
The position of the battery is shown in the corresponding engine compart-
ment diagram ⇒ page 251. The location of the battery in the luggage com-
partment can be seen in ⇒ Fig. 175.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery. 

Checking and refilling levels
WARNING
● We recommend that you use only wheels and tyres which have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.
● Avoid running the vehicle on tyres that are more than 6 years old. If
you have no alternative, you should drive slowly and with extra care at all
times.
● Never use old tyres or those with an unknown history of use.
● If wheel trims are retrofitted, you must ensure that the flow of air to
the brakes is not restricted. This could cause the brake system to over-
heat.
● All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.
For the sake of the environment
Old tyres must be disposed of according to the laws in the country con-
cerned.
Note
● For technical reasons, it is not generally possible to use the wheels from
other vehicles. This can also apply to wheels of the same model. The use of
wheels or tyres which have not been approved by SEAT for use with your
model may invalidate the vehicle's type approval for use on public roads.
● If the spare wheel is not the same as the tyres that are mounted on the
vehicle (e.g. winter tyres) you should only use the spare tyre for a short peri-
od of time and drive with extra care. Refit the normal road wheel as soon as
possible. Wheel bolts
Wheel bolts must be tightened to the correct torque.
The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped
bolt heads must be used. This ensures that wheels are fitted securely and
that the brake system functions correctly.
In certain circumstances, you should not use wheel bolts from a different
vehicle, even if it is the same model ⇒ page 183.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.
● The wheel bolts must be clean and turn easily. Never apply grease or
oil to them.
● Use only wheel bolts which belong to the wheel.
● If the prescribed torque of the wheel bolts is too low, they could loos-
en whilst the vehicle is in motion. Risk of accident! If the tightening tor-
que is too high, the wheel bolts and threads can be damaged.
CAUTION
The prescribed tightening torque for wheel bolts for steel and alloy wheels
is 120 Nm. 

218If and when
WARNING
Switch on the hazard warning lights and place the warning triangles in
position. This is for your own safety and also warns other road users.
CAUTION
If you have to change the wheel on a slope, it is essential to lock the parallel
wheel on the same axle as that to be changed, with a wedge or similar in
order to immobilise the vehicle.
Note
Please observe legal requirements when doing so. 
Changing a wheel
Change the wheel as described below
– Remove the hub caps or the integral trim .
– Slacken the wheel bolts .
– Raise the vehicle with the jack at the corresponding point.
– Remove the wheel and then fit the spare wheel.
– Lower the vehicle.
– Tighten the wheel bolts firmly with the box spanner.
– Replace the hub cap. After changing a wheel
After changing the wheel there are still tasks to complete.
– Put the tools and jack back in the luggage compartment.
– Place the wheel with the defective tyre in the luggage compart-
ment and secure it.
– Check the tyre pressure of the newly fitted tyre as soon as pos-
sible.
– Have the tightening torque of the wheel bolts checked as soon
as possible with a torque wrench. The prescribed torque must
be 120 Nm.
Note
● If you notice that the wheel bolts are corroded and difficult to turn when
changing a wheel, they must be replaced before having the wheel bolt tight-
ening torque checked.
● For safety reasons, drive at moderate speeds until the wheel bolt tight-
ening torque has been checked. 

219
If and when
Wheel covers*
The wheel covers must be removed for access to the wheel
bolts
Fig. 135 Remove the
complete hub cap
Removing
– Remove the wheel cover using the wire hook ⇒ Fig. 135.
– Hook this into one of the cut-outs of the wheel cover.
Fitting
– Fit the wheel cover onto the wheel rim by pressing it firmly. Put
pressure initially on the point of the cut-out for the valve. Next
fit the rest of the hubcap Loosening the wheel bolts
The wheel bolts must be loosened before raising the vehicle.
Fig. 136 Changing a
wheel: loosen the wheel
bolts
Loosening
– Fit the box spanner as far as it will go over the wheel bolt.
– Grasp the box spanner by the end turn it about one full turn to
the left ⇒ Fig. 136.
Tightening
– Fit the box spanner as far as it will go over the wheel bolt.
– Grasp the box spanner close to the end and turn the bolt to the
right until it is secured.
– An adapter is required to unscrew or tighten the anti-theft
wheel bolts. 
