If and when
254Bulb changeGeneral notesBefore changing any bulb, first turn off the failed component.
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 following spare bulbs, which are essential for road safety,
should be kept in the vehicle.

24)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.25)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.26)Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it
will not work in either position or Stop.

Sunroof light– Carefully remove the lamp, using the flat side of the screwdriver,
as shown in the figure ⇒fig. 181 . – Remove the bulb, moving it in the direction of the arrow and
outwards ⇒fig. 181 .
– Installation is in the reverse order.
Jump-startingJump leads
The jump lead must have a su fficient 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 the standard DIN 72553 (see manufacturer's
documentation). 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 vehicle elec-
trical system.

If and when
264How to jump start: description⇒ fig. 182 shows the flat battery 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. 182
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 lead s, 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 which 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 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 215, “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, danger
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 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.

If and when
266Towing 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 263.
However, if your vehicle has to be tow-started:
– Engage the 2
nd or the 3
rd 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.
CommentsPlease 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 earlier than you
would normally, but with a more gentle pressure on the brake.
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. Inexperi-
enced drivers should not attempt to tow-start or tow away another vehicle.

Safety First
Controls and equipment
Practical tips
Technical Data
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 over-
loading 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 apply
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 when towing a vehicle.•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 gearbox,
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 must 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.Trailer eyes
