 Coolant
First read and observe the introductory information and safety warn-ings
on page 16.
The warning light  comes on for a few seconds when the ignition is switched
on.
If the warning light 
lights up or flashes, either the coolant temperature is too
high or the coolant level is too low.
An audible signal sounds as a warning tone.
Stop the vehicle, switch off the engine, check the level of the coolant » page 132,
and refill the coolant if necessary » page 133.
Do not continue your journey if for some reason it is not possible to top up the
coolant under the prevailing conditions. This can cause serious engine damage.
Therefore, switch the engine off and seek help from a specialist garage.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the radiator fan. Check the fuse for the radia-
tor fan, replace if necessary » page 156, Fuses in the engine compartment .
Do not continue driving if the warning light 

does not go off even though the
coolant level is correct and the fuse for the fan is in working order!
Seek help from a specialist garage.
WARNINGIf you have to stop for technical reasons, then park the vehicle at a safe dis- tance from the traffic, switch off the engine and activate the hazard warning
lights » page 36 .

The warning light  comes on for a few seconds when the ignition is switched
on.
If the warning light after switching on the ignition or when driving lights up con-
tinuously, a fault exists in the electromechanical power steering.
› If the
yellow warning light lights up
, this indicates a partial failure of the
power steering and the steering forces can be greater.
› If the
red warning light lights up
, this indicates a complete failure of the pow-
er steering and the steering assist has failed (significantly higher steering forces).

 Electronic Stability Control (ESC)
First read and observe the introductory information and safety warn-
ings
on page 16.
The warning light flashes 
to show that the ESC is currently operating.
If the warning light 
lights up, there is a fault in the ESC.
As the ESC operates in conjunction with the ABS, the ESP warning light will also come on if the ABS system fails.
If the warning light 
comes on immediately after starting the engine, the ESC
can be switched off for technical reasons. In this case, the ESC can be switched on again by switching the ignition on and off. If the warning light goes out, the ESC is fully functional again.

18Using the system

With vehicles with a manual gearbox, do not drive at unnecessarily low engine
speeds. Shift down a gear when the engine is no longer running smoothly. Ob-
serve the recommended gear » page 12, Recommended gear .
CAUTION
■
The engine is not protected from excessive engine revs caused by shifting
down at the wrong time. This can result in a sudden increase in revs beyond the
permissible maximum rpm, thereby causing engine damage.■
Never rev up a cold engine when the vehicle is stationary or when driving in in-
dividual gears.
For the sake of the environment
Do not drive at unnecessarily high engine speeds. Shifting up sooner helps save
fuel, reduces engine noise and protects the environment.
New tyres
First read and observe the introductory information given on page 73.
New tyres must firstly be “run in” since they do not offer optimal grip at first.
Therefore, drive especially carefully for the first 500 km or so.

New brake pads
First read and observe the introductory information given on page 73.
New brake pads do not initially provide optimal braking performance. They firstneed to be “run in”. Therefore, drive especially carefully for the first 200 km or so.

The technical requirements for low fuel usage and economic efficiency of the ve-
hicle have already been built into the vehicle at the works. ŠKODA places a partic-
ular emphasis on minimising negative effects on the environment.
It is necessary to take note of the guidelines given in this chapter in order tomake best use of these characteristics and to maintain their effectiveness.
Fuel consumption, environmental pollution and the wear to the engine, brakes
and tyres depend essentially on the following three factors:
› your personal driving style
› operating conditions
› technical requirements
The fuel economy by can be improved by 10 -15 % by always looking ahead and
driving in an economical way.
Fuel consumption is also be influenced by external factors which are beyond the
driver's control. Consumption increases during the winter or under difficult condi-
tions, on poor roads, etc.
Fuel consumption can vary considerably from the manufacturer's data, as a result
of outside temperatures, weather and driving style.
Such an engine speed should be adhered to when accelerating, in order to avoid a
high fuel consumption and resonance of the vehicle. 
74Driving

In vehicles not equipped with the START-STOP system, turn off the engine when
in a traffic jam, at a level crossing or traffic lights with longer wait times.
Even after just 30 – 40 seconds you will have saved more fuel than that is needed
when you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly
high in the warming-up phase. Therefore, start driving as soon as the engine has
started, High engine speeds should however be avoided.
Avoiding short distances
Fig. 75
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
First read and observe the introductory information and safety warn-
ings on page 74.
Short distances result in an above-average high fuel consumption. We therefore
recommend avoiding distances of less than 4 km if the engine is cold.
A cold engine consumes the most fuel immediately after the start. Fuel consump-tion drops to 10 litres/100 km after just 1 kilometre. The consumption stabilises
once the engine and catalytic converter have reached their operating tempera- ture.
An important factor in this connection is also the ambient temperature. The im-
age » Fig. 75 shows the different levels of fuel consumption after driving a certain
distance at a temperature of +20 °C and at a temperature of -10 °C.
The vehicle has a higher fuel consumption in winter than in summer.

Checking tyre inflation pressure
First read and observe the introductory information and safety warn-ings
on page 74.
Tyres which are correctly inflated save fuel.
Always ensure the tyre inflation pressure is correct. If the inflation pressure is too
low, the tyres will have to overcome a higher rolling resistance. This will not only increase fuel consumption but also tyre wear and the driving behaviour will wor-
sen.
Always check the tyre inflation pressure when the tyres are cold.

Avoiding unnecessary ballast
First read and observe the introductory information and safety warn-
ings
on page 74.
Transporting ballast costs fuel.
Each kilogramme of weight increases the fuel consumption. Therefore, we rec-
ommend to carry no unnecessary weight.
It is particularly in town traffic, when one is accelerating quite often, that the ve-
hicle 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.
At a speed of 100 - 120 km/h, your vehicle that is fitted with a roof rack crossmember without a load will use about 10 % more fuel than normal due to the in-
creased aerodynamic drag.

Regular maintenance
First read and observe the introductory information and safety warn-
ings
on page 74.
A poorly tuned engine uses an unnecessarily high amount of fuel.
By having your vehicle regularly maintained by a specialist garage, you create the conditions needed for economical driving. The maintenance state of your vehicle has a positive effect on traffic safety and value retention 

This chapter contains information on the following subjects:
Electronic Stability Control (ESC)
80
Antilock Braking System (ABS)
81
Traction Control System (TCS)
81
Electronic Differential Lock (EDL)
81WARNING■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then fail to function – risk of accident!■
Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety provided by the brake assist systems
must not tempt you to take safety risks – risk of accident!
■
In the event of an ABS fault, visit a specialist garage immediately. Adjust
your style of driving according to the damage to the ABS, as you will not know
the exact extent of the damage or the extent to which this is limiting the
braking efficiency.
CAUTION
■ All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure the brake assist systems operate correctly.■
Changes to the vehicle (e.g. to the engine, brakes, chassis) can influence the
functionality of the brake assist systems » page 110, Modifications, adjustments
and technical alterations .
■
If a fault occurs in the ABS system, the ESC, ASR and EDL will also fail to work.
An ABS fault is indicated with the warning light  » page 19 .

Electronic Stability Control (ESC)
First read and observe the introductory information and safety warn-
ings
on page 80.
The ESC system helps improve control of the vehicle in situations where it is be-
ing operated at its dynamic limits, such as a sudden change to the direction of
travel. Depending on the conditions of the road surface, the risk of skidding is re-
duced, thereby improving the vehicle's driving stability .
The ESC system is automatically activated each time the ignition is switched on.The direction which the driver wishes to take is determined based on the steering angle and the speed of the vehicle and is constantly compared with the actualbehaviour of the vehicle. In the event of deviations, such as the car beginning to
skid, the ESC system will automatically brake the appropriate wheel.
During an intervention of the system, the warning light 
flashes in the instru-
ment cluster.
The following systems are integrated into the electronic stabilisation control
(ESC) :
› Antilock brake system (ABS),
› Traction control (TCS);
› Electronic Differential Lock (EDL)
› Hydraulic Brake Assist (HBA)
› Hill Hold Control (HHC).
In the event of an ESC fault, the ESC warning light 
illuminates in the instru-
ment cluster » page 18.
Hydraulic Brake Assist (HBA)
HBA increases the braking effect and helps to shorten the braking distance.
The HBA is activated by very quick operation of the brake pedal. In order to ach-
ieve the shortest possible braking distance, the brake pedal must be applied firm-
ly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is released. The ABS is activated faster and more effectively with the intervention of the HBA.
Hill Hold Control (HHC)
When driving on slopes, HHC allows you to move your foot from the brake pedal to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brakepedal for approx. 2 seconds after the brake pedal is released. 

CNG labels
126WARNING■When operating a CNG-powered vehicle, the national legal requirements
must be observed.■
If a fault occurs or a leak in the natural gas system is suspected or if you
smell gas, proceed as follows: ■Stop immediately and switch off the ignition (this will close the solenoid
valves on the natural gas tanks automatically);
■ Open the doors to ventilate the vehicle sufficiently;
■ Immediately extinguish cigarettes, and remove and switch off other spark-
or fire-causing objects from the vehicle immediately. ■ Seek help from a specialist garage to correct the gas system fault.
■
The following are considered faults on the gas system:
■ Gas leakage from any part of the gas system as well as an error on the
ventilation system.
■ Continuous gas venting through the safety valves.
■ Cracks or damage that could result in a gas leak.
■ Fault in the reduction device, the pressure regulator, gas mixer or in the
injection valves, the pressure gauge, the shut-off or check valves and tank
fixtures.
■ If gas flows into the gas mixer or into the injection valves though the en-
gine is stopped.
■ Exceeding the permissible limits for contaminants in the exhaust gas.
■
Regular gas system checks must be carried out in order to operate a natural
gas vehicle. The vehicle owner is responsible for properly conducted tests.
■
The natural gas tanks must not be exposed to a heat source.
■
Always switch off the ignition in case of an accident or vehicle fire!
■
It is prohibited to drive into automatic car washes, enclosed storage places,
garages and similar areas where it is specifically forbidden to enter with CNG vehicles.

RefuellingFig. 100
Fuel filler
First read and observe the introductory information and safety warn-ings on page 123.
The gas filler tube for refuelling with natural gas is located behind the fuel filler
flap next to the petrol filler tube.
The filling couplings of the natural gas refuelling systems may differ in handling.
When refuelling with natural gas at unfamiliar refuelling systems, you should
seek help from trained fuel station staff. If unsure, have the refuelling done by
trained fuel station staff.
The operating instructions of the refuelling system must always be followed.

124General Maintenance

In the following situation, it is possible that the tank cannot be fully filled with
natural gas.
› At very high ambient temperatures. The natural gas refuelling systems have
overheating protection. When the ambient temperature reaches a predefined value, the refuelling system automatically switches off.
› If the refuelling system has been in operation for a longer period, the filling
pressure of the natural gas refuelling system slightly drops.WARNING■ Stop the engine before refuelling.■Always switch off your mobile phone, do not smoke and do not use open
flames when refuelling with natural gas – risk of explosion!■
When refuelling, never get into the vehicle. If you have to get into your vehi-
cle in exceptional cases, close the door and touch a metal surface before you
touch the filling coupling again. This will avoid electrostatic discharges, which
may generate sparks. Sparks can cause a fire during refuelling.
■
Natural gas is highly explosive and flammable. Incorrect refuelling or improp-
er handling of natural gas can cause a fire, an explosion and injuries.
Note
■ The natural gas system of your vehicle is suitable both for fuelling from small
compressors (slow fuelling) and for fuelling from natural gas stations with large
compressors (quick fuelling).■
Noises that occur during refuelling represent no risk.
■
If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not indi- cate exactly the same level as was the case immediately after refuelling when theengine is restarted. This is not due to any system leakages but a drop in pressurein the natural gas fuel tank due to technical reasons after a cooling phase directly
after refuelling.
■
For frequent short-haul traffic, especially at low outside temperatures, the vehi-
cle is driven more frequently in petrol mode than in natural gas mode. This is why the petrol tank runs empty faster than the natural gas tank.
■
The capacity of the natural gas tank is about 11 kg, of which about 1.5 kg are a
reserve.
■
The capacity of the petrol tank is about 10 l, of which about 5 l are a reserve.

Automatic switching from CNG to petrol mode
First read and observe the introductory information and safety warn-
ings
on page 123.
The vehicle automatically switches over from CNG mode to petrol mode when the following conditions are met:
› when starting the engine, if the coolant temperature is below 15 °C,
› when the natural gas tank is empty,
› after refuelling with natural gas.

Natural gas as fuel
First read and observe the introductory information and safety warn-ings
on page 123.
Natural gas is an alternative fuel for motor vehicles. Its main component is meth-
ane (CH 4). The rest is carbon dioxide and lower hydrocarbons.
The strict legal requirements for exhaust emissions of motor vehicles are decisive for the current significance of natural gas. In direct comparison to all other fossil
fuels, natural gas is one of the fuels which cause the lowest emissions.
Natural gas is odourless and lighter than air. For safety reasons, it is saturated
with odorous substances, so that is perceived even in very small amounts.

Regular gas system checks
First read and observe the introductory information and safety warn-ings
on page 123.
Every two years, the following inspections must be carried out:
› Check the condition of the fuel filler cap, filler neck and sealing ring, and clean
sealing ring if necessary.
› Check gas system for leaks.
The following checks must be carried out every four years: › Check gas tank mounting for secure attachment and possible damage.
The gas tank must be filled prior to the regular gas system check.

Safe natural gasFirst read and observe the introductory information and safety warn-ings
on page 123.
The safety concept of the natural gas system ensures safe operation. It is equip-
ped with the following security features.
› At each natural gas tank, there is a solenoid valve that closes automatically af-
ter turning off the ignition or when running in petrol mode.
› A thermal fuse prevents uncontrolled rise in pressure in the natural gas tank in
case of fire.
› A flow limiter prevents sudden emptying of the natural gas tank in case the
pressure system is damaged.
› All the attachment points and materials are designed for maximum safety.

Natural gas quality and consumption
First read and observe the introductory information and safety warn-ings
on page 123.
Natural gas is divided into quality groups H-gas and L-gas. The two types of gas
are subdivided according to their calorific value and nitrogen and carbon dioxide
contents. H-gas has a higher calorific value and lower nitrogen or carbon dioxide
content than L-gas.
The higher the calorific value of natural gas, the lower is the consumption. How-
ever, the calorific value and the nitrogen and carbon dioxide contents can vary
within a quality group. Therefore, the consumption of the vehicle may even vary
when driving with only one natural gas quality (either only H-gas or L-gas).
The engine control of your vehicle automatically adjusts to the different natural
gas qualities. Therefore both natural gas qualities can be mixed in the fuel tank. It is therefore not necessary to run the natural gas tank completely empty to fill up
another quality.

WARNINGObserve the following information regarding the wheel bolts.■The wheel bolts must be clean and must turn easily. Never apply grease or
oil.■
The prescribed tightening torque for the wheel bolts is 110 Nm for steel and
light alloy wheel rims.
■
If the wheel bolts are tightened to an insufficient tightening torque, the
rims may come loose when the car is moving – risk of accident! A tightening
torque which is too high can damage the bolts and threads and this can result
in permanent deformation of the contact surfaces on the rim.
■
If the wheel bolts are handled incorrectly, the wheel may come loose when
the car is moving – risk of accident!
WARNINGObserve the following information regarding the spare wheel.■Only use the spare wheel for as long as is necessary.■
Never drive with more than one spare wheel attached.
■
The snow chains cannot be used on the spare wheel.
CAUTION
■ If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 141, Spare wheel .■
Protect the tyres from contact with oil, grease and fuel.
■
Replace lost valve caps.
■
If, in the event of a puncture, it is necessary to fit a spare wheel with a tyre
without a dedicated running direction or with the opposite direction of rotation, drive carefully as the optimal characteristics of the tyre are no longer applicable in
this situation.
For the sake of the environment
Tyres that are insufficiently inflated increase your fuel consumption.
Note
■ We recommend that any work on the wheels or tyres be carried out by a spe-
cialist garage.■
We recommend that you use wheel rims, tyres, full wheel trims and snow chains
