– If you have switched the ignition off and on again, you must
then once again activate the sensor by moving the lever into
home position , and then back into position .
The windscreen wipers and the windscreen washer system only operate
if the ignition is switched on.
The windscreen washer nozzles are heated* when the ignition is switched
on.
The rain sensor* automatically regulates the break between the individual
wiper strokes depending on the intensity of the rain.
Caution
In frosty weather, please first of all check whether the windscreen wiper
blades are not frozen to the windscreen before switching them on.
Switching on windscreen wipers when the blades are frozen to the wind-
screen may result in damage both to the blades and the motor of the wind-
screen wipers!
Headlight cleaning system*
The headlight lenses are cleaned, when main headlights are switched on
by holding the lever for about 2 seconds in the position ⇒page 64.
The headlight washer nozzles are moved forward out of the bumper by the
water pressure for cleaning the headlights.
You should remove stubborn dirt (such as insect residues) from the head-
light lenses at regular intervals, for example when refuelling. Please refer
to the notes ⇒page 192.
You should remove any snow from the fixtures of the washer nozzles and
clear ice in winter with a de-icing spray in order to ensure proper operation
of the cleaning system.
WARNING
Properly maintained windscreen wiper blades are essential for
clear visibility and safe driving ⇒page 66, “Replacing windscreen
wiper blades”.

Note
•You have to adjust the inflation pressure of the tyres to the load of the
car - refer to tyre inflation pressure sticker on the inside of the fuel filler
flap.
•The backrest of the rear seats is a fixed element and can therefore not
be folded forward to increase the size of the luggage compartment!
Lashing eyes
Eyes are located on the sides of the loading area for lashing the goods to
be loaded ⇒fig. 62 .
You can also attach a securing net* to these eyes for lashing small objects.
The securing net* and the fixing instruction is located in the well under the
floor covering of the lugagge compartment behind the spare wheel.
WARNING
•Please note that the handling properties of your vehicle may be
affected when transporting heavy objects as a result of the
displacement of the centre of gravity. The speed and style of
driving must be adjusted accordingly.
•The items carried in the luggage compartment should be stored
in such a way that no objects are able to slip forward if there are
any sudden driving or braking manoeuvres undertaken - risk of
injury!
•Never drive with the boot lid slightly ajar or even fully opened
otherwise exhaust gases may get into the interior of the vehicle -
risk of poisoning!
•On no account exceed the permissible axle loads and the
permissible gross weight of th e vehicle - risk of accident!
WARNING
The load to be transported must be fixed in place in such a way that
it cannot move during the journey and when braking.

Starting-off and Driving
116
•The clutch pedal should be fully depressed when starting the engine
which means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be
damage to the starter.
The engine running noises may louder at first be louder for a short time
after starting the cold engine until oil pressure can be built up in the
hydraulic valve clearance compensation. This is quite normal and is not
an operating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid
⇒ page 236.
It is only possible to tow-start vehicles fitted with a manual gearbox. The
tow-starting distance must not be more than 50 metres ⇒page 238.
Caution
•Avoid high engine revolutions, full throttle and high engine loads as
long as the engine has not yet reached its normal operating temperature
- risk of damaging the engine!
•Do not allow the engine to idle for long periods. If vehicle is stationary,
there is not sufficient air flowing through the cooler. In certain specific situ-
ations it can happen that the engine overheats - risk of engine damage!
•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. This enables you to avoid unnecessary pollutant emissions.
Petrol engine
These 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 electrical fuel pump is defect if the
engine still does not start ⇒page 241.
•Contact the nearest Škoda dealer 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 engine
Glow 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 temperature.
The preglow indicator light
 comes on after the ignition has been
switched on.
WARNING
There is the danger of poisoning if the engine is left running in an
enclosed space!

Driving and the Environment
182
Avoid driving short distances
Short distances result in an above-average high fuel
consumption.
– Avoid driving a distance of no more than 4 km if the engine is
cold.
The engine and catalytic converter must first have reached their optimal
operating temperature in order to effectively reduce fuel consumption
and pollutant emissions.
The cold engine of a mid-range vehicle consumes 30 - 40 litres/100 km.
of fuel immediately after starting. Fuel consumption drops to 20 litres/100
km. after just 1 kilometre. The engine reaches its operating temperature
only after about four kilometres and the fuel consumption then stabilizes.
You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature.
The ⇒fig. 149 shows the different fuel consumptions for the same distance, on the one hand at +20°C and on the other hand at -10°C. Your
vehicle has a higher fuel consumption in winter than in summer.
Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all
times. The rolling resistance will be increased if the tyre filling pressure is
too low. This will not only increase fuel consumption but also tyre wear
and the driving behaviour will worsen.
Always check the inflation pressure of the tyres when
cold.
Do not drive with winter tyres all year round for this costs about 10 %
more fuel. Winter tyres are also louder.
No unnecessary ballast
Transporting ballast costs fuel.
The fact that every kilogram of extra weight increases your fuel consump-
tion means that it is worth taking a look in the luggage compartment to
avoid transporting any unnecessary ballast.
It is particularly in town trafffic, when one is accelerating quite often, that
the vehicle weight will have a significant effect upon the fuel consumption.
A rule of thumb here is that an increase in weight of 100 kilograms will
cause an increase in fuel consumption of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of conven-
ience, although you no longer need it. The increased aerodynamic drag of
your vehicle causes it to use about 1 litre more fuel than normal at a speed
of 100 - 120 km/h, even when you are not carrying a load on the roof.

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 42.
– 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. 151.
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 198.
The fuel tank has a capacity of about 62 litres.
Caution
•Remove any fuel which has spilled onto the paintwork of your vehicle
immediately. This particularly applies to biodiesel - risk of paint damage!Fig. 151 Filler flap with
cap unscrewed
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.
