Winter conditions
During the winter, the starting power may be
reduced, and if necessary, the battery should
be charged ››› in Important safety warn-
ings for handling a vehicle battery on
page 206 Important safety warnings for
handling a vehicle battery All work on batteries requires specialist
knowledge. Please refer to a SEAT Official
Service or a workshop specialising in batter-
ies: risk of burns or exploding battery!
The battery must not be opened.
Never try to
change the fluid level of the battery. Other-
wise explosive gas is released from the bat-
tery that could cause an explosion. 
Wear eye protection.

Battery acid is very corrosive and caustic. Wear
protective gloves and eye protection. In the event
of electrolyte splashes, rinse off with plenty of
water.

Fires, sparks, open flames and smoking are pro-
hibited.

The battery should only be charged in a well-ven-
tilated zone. Risk of explosion!

Keep children away from acid and batteries!
WARNING
● When repairing or working on the electrical
system, proceed as follows:
–1. Remove the key from the ignition. The
negative cable on the battery must be
disconnected.
– 2. When the repair is finished, reconnect
the negative pole of the battery. ●
Switch off all electrical devices before re-
connecting the battery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Ensure that the vent hose is always connec-
ted to the battery.
● Never use damaged batteries. This could
cause an explosion! Replace a damaged bat-
tery immediately. CAUTION
● Never disconnect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components. Charging the battery

Wheels
Removing the temporary spare wheel
– Lift and hold up the floor panel to remove
the temporary spare wheel ››› Fig. 181 .
– Turn the thumb wheel anti-clockwise.
– Take out the temporary spare wheel.
Chains
For technical reasons, snow chains must not
be used on the temporary spare wheel.
If you have a puncture on one of the front
wheels when using snow chains, fit the tem-
porary spare wheel in place of one of the rear
wheels. Fit the snow chains on the rear wheel
that you have removed and replace the punc-
tured front wheel with this wheel. WARNING
● After fitting the temporary spare wheel,
check the tyre pressures as soon as possible.
Failure to do so may cause an accident. The
tyre pressures are listed on the inside of the
fuel tank flap.
● Do not drive at over 80 km/h (50 mph)
when the temporary spare wheel is fitted on
the vehicle: risk of accident!
● Avoid heavy acceleration, hard braking and
fast cornering: risk of accident!
● Never use more than one temporary spare
wheel at the same time, risk of accident. ●
No other type of tyre (normal summer or
winter tyre) may be fitted on the compact
temporary spare wheel rim.
● If you are driving using the spare wheel,
the ACC system could automatically switch
off during the journey. Switch off the system
when starting off. Extraction of the spare wheel in

speakers (with
subwoofer)* –
Disassemble the subwoofer's
floor panel
(c
arpet) as follows:
– LEON/LEON SC model: first, pull the carpet
in the direction of the backrest and then
pull it upwards to remove it. LEON ST mod-
el: lift and secure the floor storage com-
par
tment as explained in ››› page 121.
– Disconnect the subwoofer's speaker cable.
– Turn the sec

uring wheel anti-clockwise.
– Remove the subwoofer speaker and the
s

pare wheel.
– When replacing the spare wheel, place the
subwoofer speaker in the direction indica-
ted b

y the arrow and with the word
“FRONT” facing forward.
– Reconnect the speaker cable and firmly ro-
tate the securing wheel clockwise so that the subwoofer system and wheel are firmly
in place.
Winter service Winter tyres –
Winter tyres must be fitted on all four
wheels.
– Only use winter tyres that are approved for
your vehicle.
– Please note that the maximum permissible
speed for winter tyres may be lower than
for summer tyres.
– Also note that winter tyres are no longer ef-
fective when the tread is worn down.
– Af

ter fitting the wheels you must always
check the tyre pressures. The correct tyre
pressures are listed on the sticker on the
inside of the fuel tank flap ›››
page 208.
In winter road conditions winter tyres will
considerably improve vehicle handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow. This applies particularly to vehi-
cles equipped with wide section tyres or with
high speed tyres (code letters H, V or Y on
the sidew

all). »

The essentials

Emergencies
● Make sure the selector lever is in the N
po-
s ition.
● The
vehicle must not be towed faster than
50 km/h (30 mph).
● The v

ehicle must not be towed further than
50 km (30 miles)
. Reason: when the engine
is not running, the gearbox oil pump does
not work and the gearbox is not adequately
lubricated for higher speeds or longer distan-
ces.
If the vehicle has to be towed with a break-
down truck
, it must only be suspended at the
front wheels. Reason: the drive shafts are lo-
cated on the front wheels. If the car is towed
with the rear wheels lifted off the road (I.e.
travelling backwards), the drive shafts also
turn backwards. The planetary gears in the
aut

omatic gearbox then turn at such high
speeds that the gearbox will be severely
damaged in a short time. Note
● If it is not possible to tow the vehicle in the
normal way, or if it has to be towed further
than 50 km (30 miles), it must be transported
on a special car transporter or trailer.
● Should the power supply to the selector
lever be interrupted in position P, the selector
lever will be locked. Before the vehicle can be
recovered/manoeuvred you must manually
release the selector lever ››› page 229. Emergency locking and
unlocking
Introduction The doors, rear lid and panoramic tilting sun-
roof can be locked manually and partially
opened, for example if the key or the central
locking is damaged.
WARNING
Opening and closing doors carelessly can
cause serious injury.
● If the vehicle is locked from outside, the
doors and windows cannot be opened from
the inside.
● Never leave children or disabled people
alone in the car. They could be trapped in the
car in an emergency and will not be able to
get themselves to safety.
● Depending on the time of the year, temper-
atures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children. WARNING
Getting in the way of the doors and the rear
lid is dangerous and can lead to serious in-
jury.
● Open and close the doors and the rear lid
only when there is nobody in the way. CAUTION
When opening and closing in an emergency,
carefully disassemble components and then
reassemble them carefully to avoid damage
to the vehicle. Locking or unlocking the driver door
