2006 SKODA OCTAVIA engine

WARNING
■ In view of the high temperatures which can be produced in the catalytic con-
verter, the vehicle should be parked in such a way that the catalytic converter
cannot come into contact with easily flammable materials under the vehicle -
risk of fire!
■ Never use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters or heat shields - risk of fire! CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring, which can result in considerable damage to parts of the en-
gine and exhaust system. ■ Just filling the tank with leaded petrol once will damage the exhaust system! ÐEconomical and environmentally friendly driving
Introductory information
Your fuel consumption, any pollution of the environmental and the wear-and-tear
to the engine, brakes and tyres, depend essentially on three factors:
› your personal style of driving;
› the conditions under which your vehicle is operated;
› technical aspects.
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, the weather and driving style.
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 to make best use of
these characteristics and to maintain their effectiveness. The optimal engine speed should be obtained when accelerating, in order to
avoid a high fuel consumption and resonance of the vehicle.
Ð Looking ahead when driving
A vehicle's highest fuel consumption occurs when accelerating, therefore unnec-
essary accelerating and braking should be avoided. If looking ahead when driving,
less braking and consequently less accelerating are required. If possible, let your
vehicle coast to a stop, or use the engine brake, if you can see that the next set
of traffic lights is on red, for example. Ð Shifting to save energy
Fig. 125
Principle sketch: Fuel consump-
tion in litres/100 km depending
on the selected gear
Shifting up early saves on fuel.
Manual gearbox › Drive no more than about one length of your vehicle in first gear.
› Shift up into the next gear at approx. 2

000 revolutions.
An effective way of achieving good fuel economy is to shift up early. Observe the
recommended gear » page 11, Recommended gear .
A suitably selected gear can have an effect on fuel consumption » Fig. 125.
Automatic gearbox › Slowly
apply the accelerator pedal. However, do not depress it to the kickdown
position.
› If the accelerator pedal is only depressed slowly on a vehicle fitted with an au-
tomatic gearbox, an economic driving programme is automatically selected.

Note
Observe the recommended gear » page 11, Recommended gear .ÐAvoiding full throttle
Fig. 126
Principle sketch: Fuel consump-
tion in litres/100 km. and speed
in km/h.
Driving more slowly means saving fuel.
Sensitive use of the accelerator will not only significantly reduce fuel consump-
tion but also positively influence environmental pollution and wear of your vehi-
cle.
The maximum speed of your vehicle should, as far possible, never be used. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The » Fig. 126 shows the ratio of fuel consumption to the speed of your vehicle.
Fuel consumption will be halved if only three-quarters of the possible top speed
of your vehicle is used. ÐReducing idling
Idling also costs fuel.
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 af-
ter 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, whereby high engine speeds should be avoided. Ð Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
By having your vehicle regularly maintained by a ŠKODA

specialist garage, you
create the conditions needed for driving economically. The maintenance state of
your vehicle has a positive effect on traffic safety and value retention
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
Also check the oil level when refuelling. Oil consumption is dependent to a con-
siderable extent on the load and speed of the engine. Oil consumption could be
as high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. The oil consumption of a
new vehicle can therefore only be correctly assessed after driving about
5 000 km. For the sake of the environment
■ Additional improvements to the fuel economy can be made by using synthetic
high-lubricity oils.
■ Regularly check the ground under the vehicle. Have your vehicle inspected by a
ŠKODA specialist garage if you find any stains caused by oil or other fluids on the
floor. Note
We recommend that your vehicle is serviced on a regular basis by a ŠKODA Serv-
ice Partner. Ð

Driving and the Environment

Avoid short distances
Fig. 127
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
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. 127 shows the different levels of fuel consumption after driving a cer-
tain distance at a temperature of +20 °C and a temperature of -10 °C. Your vehicle
has a higher fuel consumption in the winter than in the summer. ÐChecking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure the tyre inflation pressure is correct. The rolling resistance will be
increased if the tyre filling pressure is too low. This will not only increase fuel con-
sumption but also tyre wear and the driving behaviour will worsen.
Always check the tyre inflation pressure when the tyres are cold. ÐAvoid unnecessary ballast
Transporting ballast costs fuel.
Each kilogramme of weight increases the fuel consumption. It is worth checking
the boot to avoid transporting any unnecessary ballast. 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 cross
member without a load will use use about 10 % more fuel than normal due to the
increased aerodynamic drag.
Ð Saving electricity
When the engine is running, the alternator generates and supplies electrical pow-
er. If more electrical components of the electrical system are switched on, more
fuel is needed to operate the alternator. We therefore recommend switching off
electrical components if these are no longer required. Ð Environmental compatibility
Environmental protection has played a major role in the design, selection of mate-
rials and manufacture of your new

ŠKODA. Particular emphasis has been placed
on the following points:
Design measures
› Joints designed to be easily detached.
› Simplified disassembly due to the modular structure system.
› Improved purity of different classes of materials.
› Identification of all plastic parts in accordance with VDA Recommendation 260.
› Reduced fuel consumption and exhaust emission CO
2.
› Minimum fuel leakage during accidents.
› Reduced noise.
Choice of materials › Extensive use of recyclable material.
› Air conditioning filled with CFC-free refrigerant.
› No cadmium.
› No asbestos.
› Reduction in the “vaporisation” of plastics.
Manufacture › Solvent-free cavity protection.
› Solvent-free protection of the vehicle for transportation from the production
plant to the customer. £

›
The use of solvent-free adhesives.
› No CFCs used in the production process.
› Without use of mercury.
› Use of water-soluble paints.
Trade-in and recycling of old cars
ŠKODA
meets the requirements of the brand and its products with regard to pro-
tecting the environment and the preserving resources. All new ŠKODA vehicles
can be utilized up to 95 % and always 1)
be returned. In a lot of countries sufficient
trade-in networks have been created, where you can trade-in your vehicle. After
you trade-in your vehicle, you will receive a confirmation stating the recycling in
accordance with environmental regulations. Note
Detailed information about the trade-in and recycling of old cars is available from
a ŠKODA Service Partner. ÐDriving abroad
Introductory information
In certain countries it is also possible that the
ŠKODA Service Partner network is
limited or has not been established yet. This is the reason why procuring certain
spare parts may be somewhat complicated and specialist garages may only be
able to make limited repairs. ŠKODA in the Czech Republic and its importers are
happy to provide information about technical aspects of the vehicle, required
maintenance work and possibilities for getting repairs done. ÐUnleaded petrol
A vehicle fitted with a petrol engine must always be refuelled with unleaded pet-
rol » page 156, Unleaded petrol . Information regarding the locations of filling sta-
tions that offer unleaded petrol is, for example, provided by the automobile asso-
ciations. Ð Headlights
The low beam of your headlights is set asymmetrically. It illuminates the side of
the road on which the vehicle is being driven to a greater extent.
When driving in countries in which the traffic drives on the other side of the road
than in your home country, the asymmetrical low beam may dazzle oncoming
drivers. To prevent oncoming traffic from being dazzled, the headlights must be
adjusted by a

ŠKODA Service Partner.
Headlights with Xenon lights are adjusted in the menu of the information dis-
play » page 15, MAXI DOT (information display) . Note
Further information on adjusting the headlights is available from a ŠKODA Service
Partner. Ð Avoiding damage to your vehicle
To prevent damage to your vehicle, pay special attention: › When driving on poorly maintained roads and lanes
› When driving over kerb stones
› When driving up steep ramps
› So that any low-slung parts, such as the spoiler and exhaust, do not touch the
ground and get damaged
This particularly applies to models with a sport suspension and also when your
vehicle is fully laden. Ð1)
Subject to fulfilment of the national legal requirements.

Driving and the Environment

Driving through water on the street
Fig. 128
Driving through water
The following must be observed to avoid damage to the vehicle when driving
through bodies of water (e.g. flooded roads):
› Therefore determine the depth of the water before driving through bodies of
water. The water level must fit around the strut on the side member as a maxi-
mum » Fig. 128;
› Do not drive any faster than at a walking speed. At a higher speed, a water
wave can form in front of the vehicle which can cause water to penetrate into
the air induction system of the engine or into other parts of the vehicle;
› Never stop in the water, do not reverse and do not switch the engine off;
› Deactivate the START-STOP
system before driving through water » page 100,
START/STOP .WARNING
■ Driving through water, mud, sludge etc. can reduce the braking power and
extend the braking distance - risk of accident!
■ Avoid abrupt and sudden braking immediately after water crossings.
■ After driving through bodies of water, the brakes must be cleaned and dried
as soon as possible by intermittent braking. Only apply the brakes for the pur-
pose of drying and cleaning the brake discs if the traffic conditions permit this.
Do not place any other road users in jeopardy. CAUTION
■ When driving through bodies of water, parts of the vehicle such as the engine,
gearbox, chassis or electrics can be severely damaged.
■ Oncoming vehicles can generate water waves which can exceed the permissible
water level for your vehicle. ■
Potholes, mud or rocks can be hidden under the water making it difficult or im-
possible to drive through the body of water. ■ Do not drive through salt water. The salt can lead to corrosion. Any vehicle parts
that have come into contact with salt water must be rinsed immediately with
fresh water. Note
After driving through a body of water, we recommend that the vehicle is checked
by a
ŠKODA specialist garage. Ð144
Driving Tips

Towing a trailer
Towing a trailer
Technical requirements
If your vehicle has already been factory-fitted with a towing device or is fitted
with a towing device from ŠKODA Original Accessories, then it meets all of the
technical requirements and national legal provisions for towing a trailer.
On vehicles with a towing device, the ball rod is detachable and is stowed togeth-
er with separate operating instructions in the spare wheel well or in the compart-
ment for the spare wheel within the boot » page 179, Vehicle tool kit .
Your vehicle is fitted with a 13-pin power socket for the electrical connection be-
tween the vehicle and trailer. If the trailer that is to be towed has a 7-pin connec-
tor, you can use a suitable adapter from
ŠKODA Original Accessories.
If a towing device is retrofitted, it must be completed in accordance with the
manufacturer's specifications. Note
If you have any questions, please contact a ŠKODA Service Partner. ÐLoading a trailer
Loading a trailer
The vehicle/trailer combination must be balanced, whereby the maximum permis-
sible drawbar load must be utilised. If the drawbar load is too low, it jeopardises
the performance of the vehicle/trailer combination.
Distribution of the load
Distribute the load in the trailer in such a way that heavy items are located as
close to the axle as possible. Secure the items from slipping.
The distribution of the weight is very poor if your vehicle is unladen and the trail-
er is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination. Tyre pressure
Correct the tyre inflation pressure on your vehicle for a

“full load” » page 171,
Service life of tyres.
Trailer load
The permissible trailer load must not be exceeded under any circumstan-
ces » page 197, Technical data .
The trailer loads specified apply only to altitudes up to 1 000 metres above mean
sea level. As the engine output drops at an increasing altitude due to the declin-
ing air pressure and therefore the climbing ability is also reduced, this means that
the maximum permissible towed weight must be reduced by 10 % for every fur-
ther increase of 1 000 m in height. The towed weight comprises the actual weight
of the (loaded) towing vehicle and the (loaded) trailer. Always drive particularly
carefully with the trailer.
The trailer and drawbar load information on the type plate of the towing device
are merely test data for the towing device The vehicle-specific values are detailed
in the vehicle documents. WARNING
■ If the maximum permissible axle and drawbar load and the maximum per-
missible total or towed weight of the vehicle and the trailer are exceeded this
can cause accidents and serious injuries.
■ Slipping loads can significantly affect the stability and safety of the vehicle/
trailer combination, causing accidents and serious injuries. Ð Towing a trailer
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. The national legal
requirements must be observed.
Headlights
The headlight settings must be checked before starting a journey with a coupled
trailer. If necessary, adjust the settings with the headlight beam adjust-
ment » page 44 , Headlight beam adjustment .
Driving speed
For safety reasons, do not drive faster than the maximum permissible speed indi-
cated on the trailer. £
145
Towing a trailer

Immediately reduce your speed as soon as even the slightest swaying of the trail-
er is detected. Never attempt to stop the trailer from “swaying” by accelerating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first, then brake firmly. This will avoid brake jolts resulting from
the trailer wheels locking. On downhill sections shift down a gear in good time to
also use the engine as a brake.
Trailer stabilisation
The trailer stabilisation is an extension of the stabilisation control that works in
conjunction with the counter-steering assistance to reduce the amount the trail-
er "sways". After turning on the ignition, the ESC warning light  in the instru-
ment cluster lights up for about 2 seconds longer than the ABS warning light.
Prerequisites for stabilising the trailer.
› The towing device is factory-fitted or a compatible towing device has been ret-
rofitted.
› The ESC is active. The warning light
 or  in the instrument cluster is not illu-
minated.
› The trailer is electrically connected to the towing vehicle by means of the trailer
socket.
› The speed is higher than approx. 60 km/h.
› Trailers must have a fixed drawbar.
› The ESC works for both braked and unbraked trailers.
Trailer is connected to the anti-theft alarm system. › If the vehicle is factory-fitted with an anti-theft alarm system and a towing de-
vice.
› If the trailer is electrically connected to the towing vehicle by means of the trail-
er socket.
› If the electrical system of the vehicle and trailer is fully functional.
› If the vehicle is locked with the car key and the anti-theft alarm system is acti-
vated.
When the vehicle is locked, the alarm is activated as soon as the electrical con-
nection to the trailer is interrupted.
Always deactivate the anti-theft alarm system before a trailer is connected/dis-
connected. Otherwise, the anti-theft alarm system could accidentally be trig-
gered » page 31 , Anti-theft alarm system . Engine overheating
If the needle for the coolant temperature gauge moves into the right-hand area
or the red area of the scale, the speed must be reduced immediately. Stop and
switch off the engine if the warning light
 in the instrument cluster starts to
flash. Wait a few minutes and check the level of coolant in the coolant expansion
bottle » page 163, Checking the coolant level .
The following guidelines must be observed » page 20, Coolant temperature/cool-
ant level  .
The coolant temperature can be reduced by switching on the heating. WARNING
■ The increased safety offered by the trailer stabilisation must not tempt you
to take greater risks than otherwise. ■ Adapt your speed to the conditions of the road surface and to the traffic sit-
uation.
■ Improper or incorrectly connected electric cables can energise the trailer and
cause functional faults to the vehicle's entire electrical system as well as acci-
dents and severe injuries.
■ Any work on the electrical system must be carried out only by ŠKODA spe-
cialist garages.
■ Never directly connect the trailer's electrical system with the electrical con-
nections for the tail lights or other current sources. CAUTION
■ The trailer stabilisation need not be able to correctly detect all of driving situa-
tions.
■ Trailers that sway slightly are not always detected by the trailer stabilisation
and thus are not stabilised accordingly.
■ Release the pressure on the accelerator pedal if the system is being regulated.
■ Avoid abrupt and sudden driving/braking manoeuvres.
■ When the ball rod is removed, the mounting shaft must be sealed with an ap-
propriate cover. This prevents foreign matter from penetrating into the mounting
shaft. See the fitting instructions for the towing device. £
146 Driving Tips

Wheels
First read and observe the introductory information and safety warn-
ings on page 148.
Wheel rims
Also thoroughly wash the wheel rims when washing the vehicle on a regular ba-
sis. Regularly remove salt and brake abrasion from the wheel rims otherwise the
material will be affected. Damage to the paint layer on the wheel rims must be
touched up immediately.
Light alloy wheels
After washing thoroughly and treat the wheel rims with a protective product for
light alloy wheels. Products which cause abrasion must not be used to treat the
wheel rims. WARNING
Water, ice and grit in the brake system can affect the braking efficiency - risk
of accident! CAUTION
Severe layers of dirt on the wheels can also result in wheel imbalance. This may
show itself in the form of a wheel vibration which is transmitted to the steering
wheel which, in certain circumstances, can cause premature wear of the steering.
This means it is necessary to remove the dirt. Note
We recommend that any repairs to damaged paintwork are carried out by a
ŠKODA Service Partner. ÐUnderbody protection
First read and observe the introductory information and safety warn-
ings on page 148.
The underside of your vehicle is protected for life against chemical and mechani-
cal influences.ä
ä As damage to the
protective layer when driving cannot be ruled out completely,
we recommend that you inspect the protective layer on the underside of your ve-
hicle and on the chassis at specific intervals - preferably at the beginning and end
of the winter.
ŠKODA Service Partners have suitable spray products and the necessary equip-
ment available, and are familiar with the instructions for use. We therefore rec-
ommend that touch-up work or additional corrosion protection measures are car-
ried out by a ŠKODA Service Partner. WARNING
Never use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters, diesel particle filters or heat shields. When
the engine reaches its operating temperature, these substances might ignite -
risk of fire! Ð Protection of hollow spaces
First read and observe the introductory information and safety warn-
ings on page 148.
All the cavities of your vehicle which are at risk from corrosion are protected for
life by a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. If any small
amount of wax flow out of the cavities at high temperatures, these must be re-
moved with a plastic scraper and the stains cleaned using a petroleum cleaner. WARNING
Safety regulations should be observed when using petroleum cleaner to re-
move wax - risk of fire! Ð
