Note
We recommend having the vehicle checked by an authorised SEAT dealer to
guarantee the correct working order of all electrical systems. 
Changing the battery
A replacement battery must have the same capacity, voltage, current rating
and size as the original. The appropriate types of battery can be acquired
from authorised SEAT dealers.
We recommend having the battery changed by an authorised SEAT dealer,
where the new battery will be correctly installed and the original disposed
of in line with regulations. 
Automatic disconnection of electrical equipment
When heavily-charging a battery, the programme selected by the electrical
system control unit prevents the battery from automatically discharging.
This may result in the following:
● Increase in idling speed so that the alternator can supply more current
to the electrical system.
● The performance of certain electrical components could be limited or
some may switch off temporarily, e.g. the heated seats, the heated rear win-
dow, the 12V power socket.
Note
Despite any measures taken by the control unit, the battery could drain. e.g.
with the engine is switched off, the key is turned in the ignition for a long
period or the side lights or parking lights are switched on. The switching off
of certain electrical components does not impair driving comfort and the
driver will often not even realise. 

WARNING (Continued)
● Always raise the vehicle with the doors closed.
● Never place parts of your body, e.g. arms and legs, underneath the
vehicle when supported only by the jack.
● Secure the base of the jack with suitable supports so that it cannot
slip. The jack could slide if the ground below it is soft and slippery and
the vehicle could slip off it. Therefore, place the jack on a firm surface or
use a large, stable base. On a slippery surface, e.g. tiles, use a non-slip
base such as a rubber mat.
● Never start the engine when the vehicle is raised. Risk of injury.
● The jack should only be used in the correct jacking points.
CAUTION
● The prescribed tightening torque for wheel bolts on steel and alloy
wheels is 120 Nm.
● If the anti-theft wheel bolt is overly tightened, this could damage the
bolt and the adapter
Note
● The set of anti-theft wheel bolts or the adapter are available from au-
thorised SEAT dealers.
● Please observe the relevant local legal regulations when changing the
wheel. 

shop at a maximum speed of 80 km/h (50 mph). 
Jump-starting
Introduction
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. Suitable
jump leads are required. 
Safety FirstOperating instructionsPractical TipsTechnical specifications

206Self-help
Both batteries must be rated at 12 Volts. The capacity (Ah) of the booster
battery should not be significantly lower than that of the discharged battery.
Jump leads
The jump leads must be heavy enough to carry the starter current and must
be fitted with insulated battery clamps. Refer to the instructions given by
the manufacturer.
Positive cable – usually red
Negative cable – usually black
WARNING
● When it is discharged, a battery can freeze at temperatures around
0 °C (32 °F). A frozen battery must first be thawed out before connecting
the jump leads. Risk of explosion!
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 173.
● The non-insulated parts of the battery clamps must not be allowed to
touch. Additionally, the jump lead attached to the positive battery termi-
nal must not touch metal parts of the vehicle. Risk of short circuit!
● Do not connect the negative lead to the negative terminal of the dis-
charged battery. In the event of sparks when starting the engine, the ex-
plosive gas given off by the battery could catch fire.
● Position the jump leads in such a way that they cannot come into con-
tact with any moving parts in the engine compartment.
● Do not bend over the battery. Risk of acid burns!
● The screw plugs on the battery cells must be screwed in firmly.
● Keep sources of fire (flames, lit cigarettes, etc.) away from the bat-
tery. Risk of explosion!
● Never use the jump leads on batteries in which the electrolyte level is
too low. Risk of explosion and acid burns.
Note
● The vehicles must not touch each other, as electricity could flow as soon
as the positive terminals are connected.
● The discharged battery must be properly connected to the vehicle elec-
trical system.
● The jump leads should be checked in a specialist vehicle battery shop. 

directly connected to the negative terminal of the vehicle battery but must
be attached to the engine earthing point. 
Towing the vehicle
Introduction
Vehicles with manual gearbox can be towed using a towbar or tow-
rope. They can also be towed with either the front or rear wheels
lifted off the road.
Vehicles with automatic gearbox can be towed using a towbar or
towrope. They can also be towed with the front wheels lifted off the 

road. If the vehicle is towed with the rear wheels lifted off the road
the automatic gearbox will be damaged!
It is easier and safer to tow a vehicle with a towbar. A towrope
should only be used if you do not have a towbar.
Follow the instructions below when towing a vehicle:
Notes for the driver of the towing vehicle
– Engage the clutch very gently when starting to move or on vehi-
cles with automatic gearbox press the accelerator carefully.
– On vehicles with manual gearbox, the towrope must be taut be-
fore driving off.
The maximum towing speed is 50 km/h (31 mph).
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the steering wheel
lock is not engaged and the turn signals, horn and windscreen
wipers and washers can be used.
– Put the gear lever in neutral or move the selector lever to posi-
tion N (automatic gearbox).
The brake servo and power steering only work when the engine is
running. Considerably more effort is required on the brake pedal
and steering wheel when the engine is switched off.
Ensure the towrope remains taut at all times when towing.
CAUTION
● Do not tow-start the engine. Risk of engine damage! In vehicles with a
catalytic converter, unburnt fuel could reach the catalytic converter and
catch fire in it. This could damage and destroy the catalytic converter. Use
the battery from another vehicle for help in starting the engine ⇒ page 206,
Starting the engine.
● If, due to a fault, there is no oil in the gearbox, the car may only be tow-
ed with the driven wheels lifted clear of the road and transported on a spe-
cial vehicle transporter or trailer.
● If normal towing is not possible or if the vehicle is to be towed for further
than 50 km (31 miles), the vehicle must be transported on a special vehicle
transporter or trailer.
● The towrope should be slightly elastic to reduce the loading on both ve-
hicles during towing. It is advisable to use a towrope made of synthetic fibre
or similar material only.
● Do not pull too hard with the towing vehicle and always take care to
avoid jerking the towrope. When towing on a loose surface there is always a
risk of overloading and damaging the anchorage points.
● Attach the towrope or towbar only to the towline anchorages or to the
removable towing bracket ⇒  page 161, or ⇒ page 209.
Note
● We recommend you use the towrope or towbar available in the SEAT
Original Accessories programme from authorised SEAT dealers.
● Towing a vehicle requires some experience. Both drivers should be fa-
miliar with the technique required for towing. Inexperienced drivers should
not attempt to tow away another vehicle or to have their vehicle towed.
● Note the legal regulations concerning towing, particularly those regard-
ing the signalling of the towed and towing vehicle.
● The towrope must not be twisted, as under certain circumstances this
could unscrew the front towline anchorage. 

WARNING
Read and follow the warnings ⇒ page 173, Engine compartment before
starting work in the engine compartment.
CAUTION
● Never “repair” a fuse or replace it by fitting a fuse with a higher amp rat-
ing. Risk of fire! This could also cause damage to other parts of the electri-
cal system.
● If a newly replaced fuse blow again when the electrical component con-
cerned is switched on, the electrical system must be checked by an Official
Service as soon as possible.
Note
● It is advisable to always keep spare fuses in the vehicle. The spare fuse
box is available in the range of original SEAT parts.
● One single electrical component could have more than one fuse.
● Several electrical components may be protected by the same fuse. 
