2011 SKODA OCTAVIA engine

Shifting gears and saving energy
Shifting up early saves on fuel.
Fig. 142 Fuel consumption in litres/100
km and speed in km/h.
Manual gearbox
– Drive no more than about one length of your vehicle in first gear.
– Shift up into the next higher gear at approx. 2 000 to 2 500 revs.
An effective way of achieving good fuel economy is to shift up early . You will con-
sume more fuel if you drive at unnecessarily high revolutions in any given gear. To
shift in a fuel-efficient manner, follow ⇒
 page 13, Shift recommendation for chang-
ing gears.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it beyond the kickdown
position, however.
Only depress the accelerator pedal slowly if your vehicle is fitted with an automat-
ic gearbox in order to automatically select an economic driving programme. You
will achieve good fuel economy by shifting up early and shifting down late.
General
The ⇒ fig. 142 shows the ratio of fuel consumption to the speed of your vehicle in
the relevant gears. Fuel consumption in 1st

gear is the highest, while that in 5th or
the 6th gear is the lowest. Note
Also use the information supplied by the multi-functional indicator ⇒ page 14.Avoiding full throttle Driving more slowly means saving fuel.
Fig. 143 Fuel consumption in litres/100
km. and speed in km/h.
Sensitive use of the accelerator will not only significantly reduce fuel consumption
but also positively influence environmental pollution and wear of your vehicle.
You should avoid exploiting the top speed of your vehicle wherever possible. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The ⇒ fig. 143 shows the ratio of fuel consumption to the speed of your vehicle.
You will cut your fuel consumption by half if you only make use three-quarters of
the possible top speed of your vehicle. 
Reducing idling Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at a level
crossing or at traffic lights with a lengthy red phase. Even after just 30 - 40 sec-
onds 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. This is why you should drive off right after starting the
engine. Do avoid high engine revolutions at this time, however.  163

Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
Having your vehicle serviced regularly at a specialist garage enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on
the safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refuelling. Oil consumption is dependent to a consid-
erable 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. It is therefore not possi-
ble to correctly assess the oil consumption of a new vehicle until after you have
driven about 5 000 km. For the sake of the environment
● You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
● Check the ground below your car at regular intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garage if you find
any stains caused by oil or other fluids on the floor. Avoid driving short distances Short distances result in an above-average high fuel consumption.
Fig. 144 Fuel consumption in litres/100
km at different temperatures
– 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 operat-
ing temperature in order to effectively reduce fuel consumption and pollutant
emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediate-
ly after starting. Fuel consumption drops to 10 litres/100 km after just 1 kilometre.
The engine reaches its operating temperature (outside temperature and engine
dependent) only after about 4 to 10 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. 144 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. £164
Driving and the Environment

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 consumption
means that it is worth taking a look in the luggage compartment to avoid trans-
porting any unnecessary ballast.
It is particularly in town traffic, when one is accelerating quite often, that the vehi-
cle 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 convenience, al-
though you no longer need it. The increased aerodynamic drag of your vehicle
causes it to use about 10 % more fuel than normal at a speed of 100 - 120 km/h,
even when you are not carrying a load on the roof. 
Saving electricity Generating electricity costs fuel.
– Switch off electrical components as soon as you no longer need them.
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. 
Keeping a log of your fuel consumption If you really wish to keep a close check on your
fuel consumption, it is best to en-
ter the figures in a logbook. This does not take much time but is a very worthwhile
exercise. It enables you to detect any change (positive and negative) at an early
stage and to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on how,
where and in what conditions you have driven the vehicle since you last refuelled. 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 paid to a
number of aspects, including:
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.

Trade-in and recycling of old cars
ŠKODA meets the requirements of the brand and its products regarding environ-
ment and resource protection. 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 environ-
mental regulations.
Vehicles with special built-on types
Technical documents regarding changes carried out on the vehicle must be kept
by the vehicle user, in order to hand over later to the old car user. This ensures 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. 
Motoring abroad General Other circumstances may exist abroad.
It is also possible, in certain countries, that the
ŠKODA Service Partner network is
limited or has not been established yet. This is the reason why obtaining certain
spare parts may be somewhat complicated and specialist garage personnel may
only be able to make limited repairs. ŠKODA in the Czech Republic and its foreign
importers are happy to provide information about technical aspects of the vehicle,
required maintenance work and possibilities for getting repairs done. 
Unleaded petrol A vehicle fitted with a petrol engine must always be refuelled with unleaded pet-
rol
⇒ page 161

. The automobile associations can provide you with information re-
garding the locations of filling stations which offer unleaded petrol. Headlight The low beam of your headlights is set asymmetrically. It illuminates the side of
the road on which you are driving to a greater extent. If you drive abroad on the
other side of the road, you will dazzle oncoming traffic.
In order to prevent the dazzling of oncoming traffic, it is necessary that an adjust-
ment of the headlights is carried out by a specialist garage.
The adaptation of the headlights with Xenon lights (applies only to vehicles which
are designed for driving on the left and on the right) is performed in the menu
Settings Lights & Vision Travel mode in the main menu of the Information display

. 
Avoiding damage to your vehicle When driving on poor roads and lanes or when driving over kerb stones, steep
ramps, etc., you must pay particular attention to ensuring that any low-slung parts
of the vehicle, such as spoiler and exhaust, do not touch the ground and get dam-
aged.
This particularly applies to models with a lowered suspension (sport suspension)
and also when your vehicle is fully laden. 
Driving through bodies of water on roads Fig. 145 Crossing bodies of water
£1)
Subject to fulfilment of the national legal requirements. 166
Driving and the Environment

In order to avoid damage to the vehicle when driving through bodies of water (e.g.
flooded roads), observe the following:
●
Determine the depth of the water when driving through bodies of water. The
water can reach at the maximum the web on the lower sill of the vehicle
⇒ fig. 145 .
● Drive no more than at 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 induc-
tion system of the engine or into other parts of the vehicle.
● Never let the vehicle stand in the water, never drive backwards and do not
switch off the engine. WARNING
● Driving through water, mud, sludge etc. can reduce the braking power and
extend the braking distance - risk of accident!
● Avoid sudden and severe braking manoeuvres immediately after driving
through bodies of water.
● 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 purpose of drying and cleaning the brake discs if the traffic conditions per-
mit 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, catalytic converter, chassis or electrics can be severely damaged.
● Oncoming vehicles can generate water waves which can exceed the permissi-
ble 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. Immediately
rinse all the parts of the vehicle, which came into contact with the salt water, with
fresh water. Note
After driving through a body of water, we recommend that the vehicle is checked
by a specialist garage.  167

Towing a trailer
Technical requirements Your vehicle is designed primarily for transporting persons and luggage. It can,
however, also be used for towing a trailer - provided certain technical equipment
is fitted.
If your vehicle has been
factory-fitted with a towing device or has a towing device
from ŠKODA Original Accessories, then the towing device satisfies all technical
and legal requirements.
Your vehicle is fitted with a 13-pin power socket for the electrical connection be-
tween the vehicle and trailer. If the trailer which you wish to tow has a 7-pin con-
nector, you can use a suitable adapter from
ŠKODA Original Accessories.
This work must be carried out in accordance with the manufacturer's specifica-
tions if a towing device is retrofitted.
Authorised ŠKODA Service Partners can provide detailed information about retro-
fitting a towing device and for any necessary modifications to the cooling system. WARNING
We recommend that you have the towing device from ŠKODA Original Acces-
sories installed by an authorised
ŠKODA Service Partner. He is familiar with all
the relevant details relating to retrofitting such equipment. There is a risk of
an accident if the towing device is not properly fitted! 
General Maintenance Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclines and descents if you do not make
full use of the permissible trailer load.
The trailer loads specified only apply for
altitudes up to 1000 metres above mean
sea level. The fact that the engine power output drops with increasing height due
to a lowering of air pressure and thus the ability to climb, means that the towed
weight must be reduced by 10 % for every further increase of 1 000 metres in height above sea level. The towed weight is the weight of the (laden) vehicle and
the (laden) trailer together. One should take this into account before driving up to
higher altitudes.
The trailer and drawbar load information on the type plate of the towing device
are merely test data for the towing device The data relating to your vehicle,
which is often less than this test data, can be found in your vehicle registration
documents.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are located as
close as possible to the axle. Secure the items to prevent them slipping.
Tyre pressure
Correct the tyre inflation pressure on your vehicle for that of

“fully laden”
⇒  page 192. The inflation pressure of the tyres fitted to the trailer adjust in ac-
cordance with the manufacturer's recommendation.
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. Both exterior mirrors
should be attached to folding arms. Adjust the mirrors so that they provide you
with an adequate field of view to the rear.
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights.
Alter the setting as necessary with the aid of the headlight beam adjuster
⇒  page 49.
Detachable ball head
The ball head is detachable on vehicles with towing device and can be obtained
from ŠKODA Original Accessories. It is stowed together with separate fitting in-
structions in the spare wheel well in the luggage compartment of the vehicle. Note
● We recommend that you also have your vehicle inspected between service in-
tervals if you tow a trailer frequently.
● The handbrake on the towing vehicle must be put on when coupling and de-
coupling the trailer. 168
Towing a trailer

Driving Tips
–
Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to
downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is
high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for coun-
tries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when
there are unfavourable road, weather or wind conditions, particularly near acci-
dent black spots.
You must always reduce your speed immediately as soon as you detect even just
the slightest swaying of the trailer. On no account attempt to stop the trailer
from “swaying”
by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking. Shift down gears in good time before negotiating
a downhill section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engine speed when the outside temperature
is very high ⇒ page 11, Coolant temperature gauge.
If the needle of the coolant temperature gauge moves into the right-hand area or
even the red area of the scale, reduce your speed immediately. Stop and switch
off the engine if the warning light  in the instrument cluster begins flashing.
Wait a few minutes and check the level of coolant in the coolant expansion bottle
⇒  page 185, Inspecting the coolant level. Please refer to the following guidelines
⇒ page 25, Coolant temperature/ Coolant
quantity .
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear
and increasing the engine speed is not possible since the fan speed is independ-
ent of the engine speed. One should also not drop a gear for this reason when
towing a trailer as long as the engine can manage the slope without any drop in
speed.  169

CAUTION
Never wipe the headlights dry and do not use any sharp objects for cleaning the
plastic lenses, this may result in damage to the protective paintwork and conse-
quently in formation of cracks on the headlight lenses, e.g. through effect of
chemical products. 
Door and window seals The rubber seals on the doors, boot lid, bonnet, roof window and windows remain
supple and last longer if you treat them from time to time with a rubber care prod-
uct (e.g. with a spray with silicone-free oil). You also avoid premature wear of the
seals and prevent leakages in this way. It is also easier to open the doors. Rubber
seals which are well cared for also do not stick together in cold winter weather.

Locking cylinder Use specific products for de-icing locking cylinders.
Note
When washing your vehicle, ensure that as little water as possible gets into the
locking cylinders. 
Wheels Steel wheels
You should also thoroughly wash the wheels and wheel trims when giving your
vehicle its regular wash. This prevents any brake dust, dirt and road salt from
sticking to the wheel hubs. You can remove stubborn brake abrasion adhering to
the wheels with an industrial cleaner. Touch up any damage to the paintwork on
the wheels before rust is able to form.
Light alloy wheels
Regular care of light alloy wheels is necessary in order to retain their decorative
appearance over long periods. It is particularly important to remove regularly any
road salt and brake abrasion from light alloy wheels, otherwise the light metal will
suffer. Wash thoroughly and then treat the wheels with a protective product for
light alloy wheels which does not contain any acidic components. We recommend to apply a hard wax layer onto the wheel hubs every three months. You must not
use any products which cause abrasion when treating the wheel hubs. Any dam-
age to the paint layer on the wheel hubs must be touched up immediately. WARNING
One should remember when cleaning the wheels that moisture, ice and road
salt may adversely affect braking efficiency - risk of an accident! Note
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. 
Underbody protection The underside of your vehicle is protected for life against chemical and mechanical
influences.
One cannot, however, completely rule out damage to the protective layer
when
driving so we recommend that you inspect the protective layer on the underside
of your vehicle and on the chassis at certain intervals - this is best done at the be-
ginning and end of the winter - and to touch up any damaged areas.
The authorised ŠKODA Service Partners have suitable spray products available as
well as the necessary equipment and are familiar with the instructions for use.
Therefore, we recommend you have such touch-up work or additional corrosion
protection measures carried out by an authorised ŠKODA Service Partner. WARNING
Never use additional underbody protection or corrosion-protection agents for
the exhaust pipes, catalytic converters, diesel particle filter or heat shields.
When the engine reaches its operating temperature, these substances might
ignite - risk of fire! 
Protection of hollow spaces 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. £ 173
