WARNING
•
The auxiliary heating must never be op
erated in closed rooms - risk of
poisoning!•
The auxiliary heating must not be runn
ing during refueling - risk of fire.
•
The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore do not place the vehicl
e, if you wish to operate the auxiliary
heating, in such a way that the exhaust
gases of the auxiliary heating can come
easily into contact with inflammable materi
als (e.g. dry grass) or easily inflam-
mable substances (e.g. fuel run out).
Note
If the auxiliary heating runs, the fuel co
nsumption comes from the vehicle tank. The
auxiliary heating automatically controls the filling level in the fuel tank. If only a low quantity of fuel is present in the fuel tank, the function of the auxiliary heating is blocked.•
The exhaust pipe of the auxiliary heating, which is located on the underside of the
vehicle, must not be clogged and the exhaust flow must not be blocked.•
If the auxiliary heating and ventilation is
running, the vehicle ba
ttery discharges. If
the auxiliary heating and ventilation has be
en operated several times over a longer
period, the vehicle must be driven a few ki
lometers in order to recharge the vehicle
battery.•
The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.•
At low outside temperatures, this can result
in a formation of water vapour in the
area of the engine compartment. This is quite normal and is not an operating problem.•
After switching off the auxiliary heating,
the coolant pump runs for a short period.
•
The auxiliary heating and ventilation does no
t switch on or comes on, if the vehicle
battery indicates a low loading state.•
The auxiliary heating (auxilia
ry heating) does not switch on, if the following was
shown in the information display or before switching off the ignition:
Please refuel!.
.
•
The air inlet in front of the windscreen must
be free of ice, snow or leaves in order
to ensure that the auxiliary heating operates properly.
•
So that warm air can flow in
to the vehicle after switching on the auxiliary heating,
you must maintain the temperature normally selected by you (we recommend 22°C for Climatic, Climatronic and for the heat
ing turn the regulator A to the right
⇒ page 96, fig. 108
). It is recommended to put the air flow in the position
.
•
On vehicles with DPF (diesel particle filt
er) the warm coolant heats up the engine.
Direct switching on/offThe auxiliary heating (auxiliary heating and vent
ilation) can be switched on or off at any
time
directly
using the button on the operating part of the Climatic, Climatronic or
heating
⇒fig. 111
.
If the auxiliary heating and ventilation is not
switched off earlier, it switches off auto-
matically after the expiration of the set operating period, in the menu
Running time
.
Note
A radio remote control for the auxiliary heating can be obtained from Škoda original accessories.

Technical Data
•
Never leave your vehicle unattended with the engine running.Caution
•
The starter may only be operated (ignitio
n key position ), if the engine is not
running. If the starter is immedi
ately operated after switchin
g off the engine, the starter
or the engine can be damaged.•
Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper
ating temperature - risk of damaging the
engine!•
Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-
started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle
is standing. Drive off right away. Through
this the engine reaches its operating temperature more rapidly and the pollutant emis- sions are lower.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 starting after 10
seconds if the engine does not start right
awayand wait for about 30 seconds before repeating the attempt.•
It is possible that the fuse on the electric
al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary
⇒page 233.
•
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 electrical 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 the 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
awayand wait for about 30 seconds before repeating 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 233.
•
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 turnin
g the ignition key from position into
⇒ page 109, fig. 114
.
WARNING
•
Never switch off the engine before the ve
hicle is stationary - risk of accident!

Fuel

•
Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube.
Otherwise you are unintentiona
lly filling up the volume,
which in case of heat can caus
e 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 th
e pump nozzle switches off for the first time,
provided the nozzle has been operated prop
erly. Do not continue refuelling - other-
wise the expansion volume is filled up.sgg.6.book Page 202 Thursday, September 24, 2009 2:32 PM

Fuses and light bulbs
234
Fuse cover in engine compartment The fuse box in the engine compartment exists in two different versions. You can determine which version your vehicle is fitted with after removing the fuse cover at
the location of the fuses.
On some vehicles, the battery cover must be removed before removing the fuse cover ⇒ page 210.Removing fuse cover– Move the circlips
⇒fig. 193
as far as the stop, the symbol
 appears behind the
circlip and remove the cover.
Installing fuse cover– Position the fuse cover on the fuse box and
push the circlips as far as the stop -
the symbol
 is visible behind the circlip.
Caution
•
When unlocking and locking the fuse cover, it must be pressed on the sides to the
box, otherwise damage can occur to the locking mechanism.•
Carefully position the fuse
cover in the engine compartment. If the cover was not
correctly positioned, water can get into the
fuses and this results in a damage to the
vehicle!
