WARNING
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could result in fire. This could also cause
damage to other parts of the electrical system.
Note
● If a newly replaced fuse blows again after a short time, the electrical sys-
tem must be checked by a specialised workshop as soon as possible.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another location in the electrical system. ●
Always keep some spare fuses in the vehicle. These are available from
SEAT dealers.
● In addition to the fuses listed in the following tables, there are other
fuses which must be replaced by the Technical Service Workshop. 

254If and when
Bulb change
General notes
Before changing any bulb, first turn off the failed component.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a re-
duction in the bulb life and condensation on the mirror surface, thus reduc-
ing efficiency.
A bulb should only be replaced by one of the same type. The type is inscri-
bed on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle.
Main headlights
● Dipped beam – H7
● Main beam – H1
● Side light – W5W
● Turn signal – PY21W Xenon headlights
1)
/adaptive*
● Dipped and main beam – D1S 2)
● DRL – P21W SLL
● Side light – W5W
● Turn signals – PY21W
Fog lights
● Fog light – HB4
Fixed tail light
● Stop/Side light – P21W 3)
or LED module 4)
● Turn signal – P21W
Mobile tailgate light
● Fog light (driver side) – P21W
● Reverse (passenger side) – P21W
● Side light – W5W or LED module 4)
Side turn signal
● Turn signal repeater – W5W 
1)
On this type of headlight, the bulb changes must be made by the SEAT dealer, given that
complex elements must be removed from the vehicle and a reset must be made on the
automatic control system incorporated.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it will
not work in either position or Stop.
4) Only in the LED light models. The LED modules cannot be replaced. The other lights, turn
signal light, fog light and reverse light can be replaced. If the warning lamp for the brake
light or side light (LED lights) lights up, the tail light assembly should be replaced. The fail-
ure of the lamp is only shown when the LED function goes out completely. Sometimes, a
LED will stop working, without displaying the warning as the function continues to operate.

260If and when
–Take the bulbholder out pressing on the securing pins and ex-
tract it outwards ⇒ fig. 172.
– Replace the faulty bulb, rotating it to the left and outwards.
– Installation is done in the reverse order.
WARNING
If a bulb is replaced in a tail light assembly with LED, do not pull too hard
on the bulb holder. This may damage the wiring of the LED module.

Side turn signals
Fig. 173 Side turn signal
– Press the turn signal on one of its sides to take it out.
– Remove the bulb holder from the turn signal.
– Remove the failed glass bulb and replace with a new bulb. –
Insert the bulb holder in the turn signal guide until it clicks into
place.
– First place the turn signal in the opening in the bodywork, fixing
the tabs ⇒ fig. 173, arrow 1
.
– Insert the turn signal as shown by the arrow 2
⇒ fig. 173.

If and when
11. 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.
12. When the engine is running, disconnect the leads in reverse order 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 217, Working in the engine compartment.
● 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.
WARNING (Continued)
● 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 bend over 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. 

266If and when
Towing and tow-starting
Tow-starting
The use of jump leads is preferable to tow-starting.
We recommend that you do not tow-start your vehicle. Jump-start-
ing is preferable ⇒ page 263.
However, if your vehicle has to be tow-started:
– Engage the 2nd or the 3rd gear.
– Keep the clutch pressed down.
– Switch the ignition on.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts, press the clutch and move the
gear lever into neutral. This helps to prevent driving into the
towing vehicle.
WARNING
The risk of accidents is high when tow-starting. The vehicle being towed
can easily collide with the towing vehicle.
CAUTION
When tow-starting, fuel could enter the catalytic converter and damage it. Comments
Please observe the following points if you use a tow-rope:
Notes for the driver of the towing vehicle
–
Drive slowly at first until the tow-rope is taut. Then accelerate
gradually.
– Begin and change gears cautiously. If you are driving an auto-
matic vehicle, accelerate gently.
– Remember that the brake servo and power steering are not
working in the vehicle you are towing. Brake sooner than nor-
mal and pressing the pedal gently.
Notes for the driver of the towed vehicle
– Ensure that the tow-rope remains taut at all times when towing.
Tow-rope or tow-bar
It is easier and safer to tow a vehicle with a tow-bar. You should only use a
tow-rope if you do not have a tow-bar.
A tow-rope should be slightly elastic to reduce the loading on both vehicles.
It is advisable to use a tow-rope made of synthetic fibre or similarly elastic
material.
Attach the tow-rope or the tow-bar only to the towing eyes provided or a
towing bracket.
Driving style
Towing requires some experience, especially when using a tow-rope. Both
drivers should be familiar with the technique required for towing. Inexper-
ienced drivers should not attempt to tow. 

267
If and when
Do not pull too hard with the towing vehicle and take care to avoid jerking
the tow-rope. When towing on an unpaved road, there is always a risk of
overloading and damaging the anchorage points.
The ignition of the vehicle being towed must be switched on to prevent the
steering wheel from locking and also to allow the use of the turn signals,
horn, windscreen wipers and washers.
As the brake servo does not work if the engine is not running, you must ap-
ply considerably more pressure to the brake pedal than you normally would.
As the power assisted steering does not work if the engine is not running,
you will need more strength to steer than you normally would.
Towing vehicles with an automatic gearbox
● Put the selector lever into position “N”.
● Do not drive faster than 50 km/h.
● Do not tow further than 50 km.
● If a breakdown vehicle is used, the vehicle must be towed with the front
wheels raised.
Note
● Observe legal requirements when towing or tow-starting.
● Switch on the hazard warning lights of both vehicles. However, observe
any regulations to the contrary.
● For technical reasons, vehicles with an automatic gearbox must not be
tow-started.
● If damage to your vehicle means that there is no lubricant in the gear-
box, you must raise the drive wheels while the vehicle is being towed.
● If the vehicle has to be towed more than 50 km, the front wheels should
be raised during towing, and towing should be carried out by a qualified
person. ●
The steering wheel is locked when the vehicle has no electrical power.
The vehicle must then be towed with the front wheels raised. Towing should
be carried out by a qualified person.
● The towing eye should always be kept in the vehicle. Please refer to the
notes on ⇒ page 266. 
