2004 SKODA SUPERB ECU

Fuel
206
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures
operation of a vehicle using diesel fuel down to an environmental temper-
ature of -25°C.
Biofuel
We recommend refuelling with diesel fuel at temperatures below -10°C.
Caution
It is not permitted to add the various fuel additives on the market, including
petrol, to diesel fuel in order to improve its flow properties.
Refuelling
Refuelling procedure
Opening the fuel filler cap
– Unlock the fuel filler flap with the switch in the driver door
⇒page 44.
– Open the fuel filler flap fully.
– Unscrew the cap by turning it to the left.
– Place the cap onto the top of the fuel filler flap ⇒fig. 156 .
Closing fuel filler cap
– Screw on the cap by turning it to the right until it is heard to lock.
– Press the fuel tank flap closed.
The correct grade of fuel for your vehicle as well as the tyre size and infla-
tion pressures are stated on a sticker affixed to the inside of the fuel filler
flap. Further information on fuel ⇒page 204.
The fuel tank has a capacity of about 62 litres.
WARNING
Pay attention to any legal requirements if you do carry a spare
canister in the vehicle. We do not recommend carrying any fuel
canisters in your vehicle for safety reasons. The canister can be
damaged in the event of an accident and fuel may leak out.
Caution
•Remove any fuel which has spilled onto the paintwork of your vehicle
immediately. This particularly applies to biodiesel - risk of paint damage!
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to run completely empty. An irregular supply of fuel to the

Inspecting and Replenishing
210
•If you wish to work under the vehicle, you must secure the
vehicle from rolling away and support it with suitable supporting
blocks: the car jack is not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work
when the engine is running there is an additional risk from rotating
parts (e.g. the V-ribbed belt, alternator, radiator fan) and from the
high-voltage ignition system. Pl ease observe in addition the
following:
−Never touch the electrical cables of the ignition system.
− Absolutely avoid any jewellery, loose items of clothing or
long hair from getting into the rotating parts of the engine -
Hazard! Therefore remove any jewellery beforehand, tie up your
hair and wear tight fitting clothing.
•Please also comply with the warning instructions stated below
when carrying out any essential work on the fuel system or on the
electrical system:
−Always separate the car battery from the electrical system.
− Do not smoke.
− Never carry out any work close to naked flames.
− Always keep a working fire extinguisher at hand.
Caution
When replenishing fluids in the engine, always ensure that the fluids are
on no account mixed up. This may result in major operating problems and
also vehicle damage!

•Do not drive with this spare wheel at more than 80 km/h - risk of acci-
dent. Avoid accelerating at full throttle, sharp braking and fast cornering.
•The inflation pressure for this spare wheel is identical to the inflation
pressure of the standard tyres.
•Use this spare wheel only to reach the nearest service station as it is
not intended for continuous use.
Changing a wheel
Preliminary work
The following steps should be carried out before actually
changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from the traffic flow. The place you choose
should be level.
– Have all the occupants get out. While changing a wheel, the
occupants of the vehicle should not stand on the road (it is
better behind a crash barrier).
– Apply the handbrake firmly.
– Engage 1st gear or if your vehicle is fitted with an automatic
gearbox, position the selector lever into position P .
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒ page 237
out of the luggage compartment.
WARNING
•If you find yourself in flowing traffic switch on the hazard
warning lights system and place the warning triangle on the side of
the road at the prescribed distance from your vehicle while
observing all national legal provisions. In this way you are
protecting not only yourself but also other road users.
•Never start the engine with the vehicle sitting on the raised jack
- danger of suffering injury!
Caution
If you have to change a wheel on a slope first block the opposite wheel
with a stone or similar object in order to secure the vehicle from unexpect-
edly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim* ⇒page 239 or the caps
⇒ page 241.
– In the case of light alloy wheels remove the wheel trim cap ⇒page 240.
– Slacken the wheel bolts ⇒page 241.

Breakdown assistance

Installing
– First press the full wheel trim onto the wheel at the valve opening provided. Then press the full wheel trim into the
wheel in such a way that its entire circumference locks
correctly in place.
Caution
•Use the pressure of your hand, do not knock on the full wheel trim!
Heavy knocks mainly on the points where the full wheel trim has not been
inserted into the wheel, can result in damage to the guide and centering
elements of the full wheel trim.
•First check for yourself that the theft-deterrent wheel bolt is located
⇒ page 244, “Securing wheels against being stolen” in the hole in the
area of the valve before fitting the full wheel trim onto a steel wheel which
is attached with a theft-deterrent wheel bolt.
Wheel trim caps*
Removing
– Carefully ⇒fig. 178 lever off the wheel trim cap using the
removal hook .

wheel: Pulling off the

– Screw in the wheel bolts and tighten them slightly with the aid
of the hexagon socket.
– Unscrew the assembly pin and screw in the remaining wheel bolt also slightly.
The wheel bolts must be clean and must turn easily.
The hexagon socket in the handle of the screwdriver makes it simpler to
fit on the wheel bolts. The reversible blade should be pulled out for this
step.
When fitting on unidirectional tyres, ensure that the tyres rotate in the
correct direction ⇒ page 231.
Note
Do not use the hexagon socket in the handle of the screwdriver for slack-
ening or tightening the wheel bolts.
Securing wheels against being stolen
You need a special adapter for slackening the safety
wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from
the safety wheel bolt.
– Push the adapter with its toothed side into the inner toothing of the safety wheel bolt right down in such a way
that only the outer hexagon is jutting out ⇒fig. 184.
– Push the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 230.
– Reinstall the full wheel trim/wheel cap after removing the adapter or place the cap onto the safety wheel bolt.
