Bulb changeGeneral notesBefore changing any bulb first turn off the equipment concerned.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a
reduction in the bulb life and condensation on the mirror surface, thus
reducing efficiency.
A bulb should only be replaced by one of the same type. The type is inscribed
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 bulbs that most affect road safety should have spares in the
vehicle.

Note
•
Due to the difficulty in accessing the lamps, any replacement work should
be done by a SEAT dealer. However, the following is a description of how to
change the bulbs except for the fog lights and interior bulbs.
21)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.22)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 circum-
stances, there is no need to change the bulbs for the whole life of the vehicle.
23)Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it
will not work in either position or Stop position.

How to jump startIn ⇒ fig. 180, the flat battery is and the charged battery .
Jump lead terminal connections
– Switch off the ignition on both vehicles ⇒.
1. Connect one end of the red jump lead to the positive ⇒fig. 180
terminal of the vehicle with the flat battery ⇒.
2. Connect the other end of the red jump lead to the positive terminal in the vehicle providing assistance.
3. Connect one end of the black jump lead to the negative terminal on the battery of the vehicle providing assistance. 4. Connect the other end of the black jump lead to a solid metal
component which is bolted on to the engine block, or onto the
engine block itself of the vehicle with the flat battery. Do not
connect it to a point near the battery ⇒.
5. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
6. Start the engine of the vehicle with the boosting battery and let
it run at idling speed.
7. Start the engine of the car with the flat battery and wait one or two minutes until the engine is “running”.
Removing the jump leads
8. Before you remove the jump leads, switch off the headlights (if they are switched on).
9. Turn on the heater blower and rear window heater in the vehicle with the flat battery. This helps minimise voltage peaks that are
generated when the leads are disconnected.
10. When the engine is running, disconnect the leads in reverse order to the details given above.
Connect the battery clamps so they ha ve 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.

Towing and tow-startingTo w - s t a r t i n g
The use of jump leads is preferable to tow-starting.We recommend that you do not tow-start your vehicle. Jump-starting
is preferable ⇒page 248.
However, if your vehicle has to be tow-started:
– Engage the 2nd or the 3rd gear.
– Keep the clutch pressed down.
– Switch on the ignition.
– Once both vehicles are mo ving, 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.
Towing eyesPlease observe the following points if you use a tow-rope:
