ignition Seat Leon 5D 2005 Repair Manual

Checking and refilling levels
194
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.•
Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.
•
Switch off the engine and remove the key from the ignition.
•
Apply the handbrake and move the gea r stick to neutral or selector
lever to position P.
•
Keep children away from the vehicle.
•
Never touch hot engine parts. There is a risk of burns.
•
Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.
•
Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 241. The battery could
explode.
•
Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
•
Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!
•
Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
•
Always make sure you have not left any objects, such as cleaning cloths
and tools, in the engine compartment.
•
If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicl e, there is a risk of accident! A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•
If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belt s, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.
•
If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!

Checking and refilling levels
208charge. Never short the battery terminals. High-energy sparks can cause
injury.•
A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
•
Keep children away from acid and batteries.
•
Before working on the electrical system, you must switch off the
engine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only switch
off the light.
•
Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
•
When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.
•
Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never
reverse the polarity of the connections. This could cause an electrical fire.
•
Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0
°C.
•
Ensure that the vent hose is always connected to the battery.
•
Never use a defective battery. This may be fatally explosive. Replace a
damaged battery immediately.Caution
•
Never disconnect the battery if the ignition is switched on or if the engine
is running. This could damage the electrical system or electronic compo-
nents.
•
Do not expose the battery to direct sunlight over a long period of time, as
the intense ultraviolet radiation can damage the battery housing.
•
If the vehicle is left standing in cold conditions for a long period, protect
the battery from frost. If it “freezes” it will be damaged.
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the bonnet and open the battery cover at the front ⇒ in
“Safety instructions on working in the engine compartment” on
page 193 ⇒ in “Warnings on handling the battery” on
page 207.
– Check the colour display in the “magic eye” on the top of the battery.
– If there are air bubbles in the window, tap the window gently until they disperse.The position of the battery is show n in the corresponding engine compart-
ment diagram ⇒page 252.
The round window (“magic eye”) on the top of the battery changes colour,
depending on the charge level and electrolyte level of the battery.
If the colour in the window is colourless or bright yellow, the electrolyte level
of the battery is too low. Have the battery checked by a qualified workshop.
The colours green and black are used by the workshops for diagnostic
purposes.

Fuse cover underneath the steering wheel
– Switch off the ignition and the component concerned.
– Identify the fuse for the failed component ⇒page 226.
– Take the plastic clip from inside the fuse cover, fit it onto the blown fuse and pull the fuse out.
– Replace the blown fuse (which will have a melted metal strip) with a new fuse of the same ampere rating.
Fuse cover in engine compartment
– Switch off the ignition and the component concerned.
– Prise off the fuse cover in the engine compartment by pressing the tabs towards the centre of the cover ⇒page 224, fig. 153 .
– Identify the fuse for the failed component ⇒page 226.
– Take the plastic clip from inside the fuse cover (at left-hand end of the dash panel), fit it onto the blown fuse and pull the fuse out.
– Replace the blown fuse (which will have a melted metal strip) with a new fuse of the same ampere rating.
– Carefully fit the fuse cover back on to ensure no water can enter the fuse box.The individual electrical circuits are pr otected by fuses. The fuses are located
behind a cover at the left-hand end of the dash panel and on the left-hand
side of the engine compartment.
The electric windows are protected by circuit breakers. These reset automat-
ically after a few seconds when the overload (caused for example by frozen
windows) has been corrected. Colour coding of fuses
WARNING
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could re
sult 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
system must be checked by a qualified workshop as soon as possible.
•
If you replace a fuse with a stronger fuse, you could cause damage to
another location in the electrical system.
•
Always keep some spare fuses in the vehicle. These are available from
official Service. Colour

How to jump startIn ⇒ fig. 172, the flat battery is A and the charged battery B.
Jump lead terminal connections
– Switch off the ignition on both vehicles ⇒.
1. Connect one end of the red jump lead to the positive ⇒fig. 172
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 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 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 240.
However, if your vehicle has to be tow-started:
–Engage the 2
nd or the 3
rd 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:

Notes for the driver of the towing vehicle
– Drive slowly at first until the to w-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.
Fitting the towing eye
– Take the towing ring and the wheel spanner out of the vehicle tool kit.
– Pull the lower front cover down and leave the cover hanging on the vehicle.
– Remove the cover of the screw hole, insert a screwdriver into the lower slot and lever gently.
– Screw the towing eye as shown by arrow anti-clockwise to the
limit position in the front ⇒page 243, fig. 173 or rear
⇒ page 243, fig. 174 threaded hole.
– Use the wrench for leverage to tighten the towing eye.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, espec
ially when using a tow-rope. Both
drivers should be familiar with the te chnique required for towing. Inexperi-
enced drivers should not attempt to tow-start or tow away another vehicle.
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.
