Emergencies
– 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 temporary 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 punctured
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 pres-
sures 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 ac-
cident!
● 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.

Extraction of the spare wheel in vehicles with SEAT SOUND
10 speakers (with subwoofer)*
– Disassemble the subwoofer’s floor panel (carpet) as follows:
– LEON / LEON SC model: first, pull the carpet in the direction of
the backrest and then pull the carpet upwards to remove it. LEON ST Model: lift and secure the luggage compartment floor
as explained in
⇒ page 148.
– Disconnect the subwoofer’s speaker cable.
– Turn the securing wheel anti-clockwise.
– Remove the subwoofer speaker and the spare wheel.
– When replacing the spare wheel, place the subwoofer speaker
in the direction indicated by the arrow and with the word
“FRONT” facing forward.
– Reconnect the speaker cable and firmly rotate the securing
wheel clockwise so that the subwoofer system and wheel are
firmly in place. 
Jump starting Jump leads
The jump lead must have a sufficient wire cross section.
If the engine fails to start because of a discharged battery, the battery can
be connected to the battery of another vehicle to start the engine.
Jump leads
Jump leads must comply with standard DIN 72553 (see cable manufactur-
er's instructions). The wire cross section must be at least 25 mm 2
for petrol
engines and at least 35 mm 2
for diesel engines. 

Note
● The vehicles must not touch each other, otherwise electricity could flow
as soon as the positive terminals are connected.
● The discharged battery must be properly connected to the on-board net-
work. 

Jump lead terminal connections
1. Switch off the ignition of both vehicles ⇒ 
.
2. Connect one end of the red jump lead to the positive +
termi-
nal of the vehicle with the flat battery A ⇒ Fig. 172.
3. Connect the other end of the red jump lead to the positive ter-
minal +
in the vehicle providing assistance B.
4. For vehicles without Start-Stop system: Connect one end of the
black jump lead to the negative terminal –
of the vehicle pro-
viding assistance B ⇒ Fig. 172.
– For vehicles with Start-Stop system: Connect one end of the
black jump lead X
to a suitable ground terminal, a solid piece
of metal in the engine block, or to the engine block ⇒ Fig. 173.
5. Connect the other end of the black jump lead X
to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. However, connect it to
a point as far as possible from the battery A

Emergencies
6. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
8. Start the engine of the vehicle with the flat battery and wait two or three minutes until the engine is “running”.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped beam headlights (if they are switched on).
10.Turn on the heater blower and heated rear window in the vehi- cle with the flat battery. This helps minimise voltage peaks
which are generated when the leads are disconnected.
11.When the engine is running, disconnect the leads in reverse or- der to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 251.
● The battery providing assistance must have the same voltage as the
flat battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
● Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes away from batteries, dan-
ger of explosion. Failure to comply could result in an explosion.
● Observe the instructions provided by the manufacturer of the jump
leads.
● Do not connect the negative cable from the other vehicle directly to
the negative terminal of the flat battery. The gas emitted from the battery
could be ignited by sparks. Danger of explosion.
● Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
● The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead attached to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
● Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
● Do not lean on the batteries. This could result in chemical burns.
Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected. 

Tow-starting
As a general rule, tow-starting is not recommended.
– Engage 2nd or 3rd gear before moving off.
– Press the clutch and hold the pedal down.
– Switch the ignition on.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts: press the clutch and put the gear
lever in neutral.
If the engine will not start, it is best to try starting it using the battery of an-
other vehicle ⇒ page 283 before attempting to tow start. You should only try
to tow-start the engine if jump starting is not successful. Tow-starting is an
attempt to start the engine via the movement of the wheels.
When tow-starting a vehicle with a petrol engine, do not tow it more than a
short distance, otherwise unburned fuel can enter the catalytic converter
and cause damage.
WARNING
The risk of accidents is high when tow-starting, as the towed vehicle can
easily be driven into the towing vehicle.
CAUTION
Do not tow vehicles for more than 50 m. Risk of damage to the catalytic con-
verter. Towing vehicles with a manual gearbox
Towing is relatively straightforward.
Please observe the relevant instructions ⇒ page 286.
The vehicle can be towed using a tow bar or tow rope in the normal way,
with all four wheels on the road; it can also be towed with either the front or
rear wheels lifted off the road. The maximum towing speed is 50 km/h (30
mph). 
Towing a vehicle equipped with automatic gearbox
Certain restrictions must be observed when towing your ve-
hicle. Please observe the relevant instructions ⇒ page 286.
The vehicle can be towed with a tow bar or tow rope in the normal way, with
all four wheels on the ground. When doing so, please note the following
points:
● Make sure the selector lever is in the N position.
● The vehicle must not be towed faster than 50 km/h (30 mph).
● The vehicle 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 breakdown truck, it must only be sus-
pended at the front wheels. Reason: the drive shafts are located on the front
wheels. If the car is towed with the rear wheels lifted off the road (I.e. travel-
ling backwards), the drive shafts also turn backwards. The planetary gears
in the automatic gearbox then turn at such high speeds that the gearbox
will be severely damaged in a short time. 
