Technical Data
Petrol enginesThese engines are fitted with a starter system which selects the correct fuel-air
mixture for every external air temperature.•
Do not operate accelerator before and when starting engine.
•
Interrupt the attempt at star ting after 10 seconds if the engine does not start
right away and wait for about 30 seconds before repe ating the attempt.
•
It is possible that the fuse on the electrical fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary page 156.
•
Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started.
Diesel enginesGlow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside tempera-
ture.
The preglow indicator light
 comes on after the ignition has been switched on.
You should not switch on any major elec trical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
•
You should start the engine immediately after the glow plug warning light

has gone out.
•
The glow plug warning light will come on for about one second if the engine is
at a normal operating temperature or if th e outside temperature is above +5 °C. This
means that you can start the engine right away .
•
Interrupt the attempt at starting after 10 seconds if the engine does not start
right away and wait for about 30 seconds before repe ating the attempt.
•
It is possible that the fuse on the diesel preglow system is defect if the engine
still does not start. Check the fuse and replace it if necessary page 156.
•
Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank
has run completely dry - up to one minute. This is because the fuel system must first
of all be filled while the attempting to start the engine.
Switching off the engine– The engine can be switched off by tur ning the ignition key into position
 page 73, fig. 84 .
WARNING
•
Never switch off the engine before the ve hicle is stationary - risk of accident!
•
The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en gine is switched off. Because if you do
not stop as normal, this can caus e an accident and severe injuries.Caution
you should not switch the engine off right away at the end of your journey after the
engine has been operated for a lengthy period at high loads but should be allowed
it to run at idling speed for about 2 minutes . This prevents any accumulation of heat
when the engine is switched off.
Note
•
The radiator fan may continue running for a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, also
switch on again after some time if the coolant temperature rises because of an
a c c um ul a tio n o f he a t i n the en g in e o r i f the engine is warm and the engine compart-
ment is additionally heat ed by strong sunlight.
•
This is why particular care is required when carrying out any work in the engine
compartment page 131, “Working in the engine compartment”.

Caution
•
Remove any fuel which has spilled onto the paintwork of your vehicle immedi-
ately - 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 engine can result in
misfiring and unburnt fuel may get into the exhaust system, which may result in
overheating and damage to the catalytic converter.
•
Make sure that the valve is not pressed into the filler tube when inserting the
pump nozzle into the filler tube. Otherwis e you are unintentionally filling up the
volume, which in case of heat can cause an expansion of the fuel. This can lead to
an overflow of fuel or damage to parts of the fuel reservoir.
•
The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Do not continue refuelling -
otherwise the expansion volume is filled up.

Technical Data
BulbsChanging bulbsThe relevant lamp must always be switched off before a light bulb is replaced.
Defect light bulbs should only be replaced with light bulbs of the same type. The
designation is located on the light socket or the glass bulb.
Changing certain bulbs is not something which you can do yourself, but requires to
be done by a specialist. Other parts of the vehicle must be removed in order to
change the light bulbs. This applies, in particular, to bulbs which can only be reached
from the engine compartment.
We therefore recommend that you have an y bulbs changed by an authorised Škoda
Service Partner or, in exceptional cases, by calling on other professional assistance.
Please note that the engine compartment is a hazardous area page 131, “Working
in the engine compartment”.
We recommend that you always have a sm all box of replacement bulbs in your
vehicle. You can obtain replacement bulbs from Škoda original accessories or from
a specialist garage
