2014 SKODA OCTAVIA ignition

WARNING■When refuelling, never get into the vehicle. If you have to get into your
vehicle in exceptional cases, 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 highly flammable.
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.

In some countries, national legislation requires that vehicles with CNG opera-
tion be identified by one of the listed labels » Fig. 183.
Position of the CNG label » Fig. 183.
Natural gas quality and consumption
Depending on the natural gas supplier, the natural gas quality (heating value)
may vary. The engine control unit adjusts automatically to the natural gas
quality.
Automatically switching over from natural gas mode to petrol mode
The vehicle automatically switches from natural gas to petrol, for example, if
one of the following cases occurs.
› With an empty gas tank or not enough pressure in the tank.
› After refuelling with natural gas.
› At very low surrounding temperatures.
Gas smell
If you smell gas, proceed as follows.
› Stop the vehicle.
› Put out cigarettes.
› Switch off the ignition.
› Open the doors and the boot lid to ventilate the vehicle sufficiently.
› Remove any spark-producing or incendiary items from the vehicle and switch
off immediately.
› Do not continue to drive if the odour persists.
Seek help from a specialist garage to correct the gas system fault.
Regular gas system checks must be carried out at a specialist workshop on natural gas-powered vehicles.WARNINGWhen operating a CNG-powered vehicle, the national legal requirements
must be observed.WARNINGDo not underestimate the smell of gas in the car or when refuelling - risk of
fire, explosion and injury.

WARNINGWhen working in the engine compartment, injuries, scolding, accident or
fire hazards may arise. For this reason, it is essential to comply with the
warning instructions stated below and with the general applicable rules of
safety. The engine compartment of your car is a hazardous area!WARNINGInstructions before beginning work in the engine compartment■Turn off the engine and withdraw the ignition key.■
Firmly apply the handbrake.
■
For vehicles with manual transmission the lever into the neutral position.
■
On vehicles with automatic transmission, shift the selector lever into the
P position.
■
Allow the engine to cool.
■
Never open the bonnet if you can see steam or coolant flowing out of the
engine compartment – risk of scalding! Wait until the steam or coolant has
stopped escaping.
WARNINGInformation for working in the engine compartment■Keep all people, especially children, away from the engine compartment.■
Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running!
■
Do not touch any hot engine parts – risk of burns!
WARNINGInformation for working in the engine compartment with the engine run-
ning■
Pay particular attention to moving engine parts, e.g. V-ribbed belt, gener-
ator, radiator fan - danger to life!
■
Never touch the electric wiring on the ignition system.
■
Avoid short circuits in the electrical system – particularly on the vehicle's
battery.
■
Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts – risk of death! Always remove any jewel-
lery, tie back long hair and wear tight fitting clothing before completing any
work.
WARNINGInformation for working on the fuel system or the electrical system■Always disconnect the vehicle battery from the electrical system.■
Do not smoke.
■
Never work near open flames.
■
Always have a functioning fire extinguisher nearby.
WARNING■ Read the information and warning instructions on the fluid containers.■Keep the working fluids in sealed original containers and safe from peo-
ple who are not completely independent, e.g. children.■
Never spill fluids over the hot engine - risk of fire.
■
If you wish to work under the vehicle, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is
not sufficient for this – risk of injury!
CAUTION
Always top up using the correct specification of fluids. This may result in major
operating problems and also vehicle damage!
For the sake of the environment
In view of the requirements for the environmentally friendly disposal of fluids and the special tools and knowledge required for such work, we recommend
that fluids be changed by a specialist garage.
Note
■ Please consult a specialist garage for any questions relating to fluids.■Fluids with the proper specifications can be purchased from the ŠKODA Origi-
nal Accessories or from the ŠKODA Genuine Parts ranges.193Inspecting and replenishing

NoteThe location of the inspection points in the engine compartment of petrol and
diesel engines is practically identical.
Radiator fan
Read and observe
and on page 193 first.
The radiator fan is powered by an electric motor. Operation is controlled ac-
cording to the temperature of the coolant.
WARNINGAfter switching off the ignition, the fan can intermittently continue to oper-
ate for approx. 10 minutes.
Windscreen washer system

Windscreen washer fluid reser-
voir
Read and observe and on page 193 first.
The windscreen washer fluid reservoir
A
is located in the engine compart-
ment » Fig. 186 .
The cleaning fluid is provided for the cleaning of the front and rear window as
well as the headlight.
The capacity of the reservoir is about 3 litres or about 4.7 litres on vehicles that
have a headlight cleaning system 1)
.
Clear water is not sufficient to intensively clean the windscreen and head-
lights. We recommend using clean washing water together with the screen
cleaner from the range of ŠKODA Original Accessories (in winter additionally
with antifreeze) which is capable of removing stubborn dirt.
In Winter, the washing water should always be mixed with antifreeze even if
the vehicle has heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no
screen cleaner with antifreeze is available. The concentration of methylated
spirits must not be more than 15 %. The freeze protection at this concentration
is sufficient only to -5 °C.
CAUTION
■ Under no circumstances must radiator antifreeze or other additives be added
to the windscreen washer fluid.■
If the vehicle is fitted with a headlight cleaning system, only cleaning prod-
ucts which do not attack the polycarbonate coating of the headlights must be
added to the windscreen washer fluid.
■
Do not remove the filter from the windscreen washer fluid reservoir when re-
plenishing it with liquid otherwise the liquid transportation system can be con-
taminated, which can cause the windscreen washer system to malfunction.

The engine has been factory-filled with a high-grade oil that can be use
throughout the year - except in extreme climate zones.
The engine oils are undergoing continuous further development. Thus the in- formation stated in this Owner's Manual is only correct at the time of publica-
tion. 

In some countries, 4.7 ltr. applies for both variants.
195Inspecting and replenishing

Note■The battery acid level is also checked regularly by a specialist garage as part
of the inspection service.■
For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
Charging
Read and observe
and on page 200 first.
A properly charged vehicle battery is essential for reliably starting the engine.
A charging operation can be performed if the following conditions are satis-
fied.
The engine is turned off.
The ignition is switched off.
All consumers are turned off.
The bonnet is open.
“Fast charging” with high currents
›
Disconnect both battery cables (first of all “negative”, then “positive”).
›
Attach the terminal clamps of the charger to the battery terminals (red =
“positive”, black = “negative”).
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove the
mains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first of all “positive”, then “negative”).
Charging with low voltages
It is not necessary to disconnect the cables from the battery if you recharge
the vehicle battery, for example from a mini-charger.
Refer to the instructions of the charger manufacturer .
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
The vent plugs of the vehicle battery should not be opened for charging.
WARNING■ When you charge a battery, hydrogen is released, and a highly explosive
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.■
Creating a bridge between the poles on the battery (e.g. with metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the en-
gine, the ignition and all electrical components and disconnect the negative
terminal 
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START/STOP system or additional heating (auxiliary heat-
ing), do not connect the pole terminal of the charger directly to the negative
terminal of the vehicle battery, but rather only to the engine earth » page 220,
Jump-starting using the battery from another vehicle .
Replacing
Read and observe
and on page 200 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations.

CAUTION
■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 200 first.
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the bettery is subjected to heavy loads. This manifests itself by
the following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large convenience consumers, e.g. seat heaters, rear win-
dow heaters, have their power limited or in case of emergency shut off com-
pletely.
CAUTION
■ Despite such intervention by the vehicle electric system management, the
vehicle battery may be drained. For example, when the ignition is switched on
a long time with the engine turned off or the side or parking lights are turned
on during longer parking.■
Consumers which are supplied via a 12 V socket can cause the vehicle battery
to discharge when the ignition is switched off.
Note
Driving comfort is not disrupted by any shutting off of consumers. Often the
driver is not aware of it having taken place.203Inspecting and replenishing

WARNING■If you cannot inflate the tyre to at least 2.0 bar, this means the damage
sustained was too serious. The sealing agent cannot be used to seal the
tyre. 
Do not drive the vehicle. Seek help from a specialist garage.■
The tyre inflation hose and air compressor may get hot as the tyre is be-
ing inflated – risk of burning.
CAUTION
Switch off the air compressor after running 8 minutes at the latest – risk of
overheating! Allow the air compressor to cool a few minutes before switching
it on again.
Notes for driving with a repaired tyre
Read and observe
on page 218 first.
The inflation pressure of the repaired tyre must be checked after driving for 10
minutes.
If the tyre inflation pressure is 1.3 bar or less
›
 Do not drive the vehicle! You cannot properly seal with tyre with the
breakdown kit.
If the tyre inflation pressure is 1.3 bar or more
›
Set the tyre pressure back to the correct value.
›
Continue driving carefully to the nearest specialist garage at a maximum speed of 80 km/h (50 mph).
WARNING■ A tyre filled with sealant has the same driving characteristics as a stand-
ard tyre.■
Do not drive faster than 80 km/h (50 mph).
■
Avoid accelerating at full throttle, sharp braking and fast cornering.

 Introduction
This chapter contains information on the following subjects:
Jump-starting using the battery from another vehicle
220The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat.WARNING■ Pay attention to the warning instructions relating to working in the en-
gine compartment » page 192.■
A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C. If the battery is frozen, do not carry out a jump start with the bat-
tery of another vehicle – risk of explosion!
■
Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
away from the battery – risk of explosion!
■
Never jump-start vehicle batteries with an electrolyte level that is too low
– risk of explosion and caustic burns.
■
The vent screws of the battery cells must be tightened firmly.
Note
We recommend you buy jump-start cables from a car battery specialist.

Vehicles with manual transmission may be towed in with a tow bar or a tow
rope or with the front or rear wheels raised.
Vehicles with automatic transmission may be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the auto-
matic gearbox is damaged!
Driver of the tow vehicle›
Engage the clutch gently when starting off or depress the accelerator partic-
ularly gently if the vehicle is fitted with an automatic gearbox.
›
Only then approach correctly when the rope is taut.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
›
Switch on the ignition so that the steering wheel is not locked and so that
the turn signal lights, windscreen wipers and windscreen washer system can
be used.
›
Take the vehicle out of gear or move the selector lever into position N if the
vehicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the
engine is running. If the engine is not running, significantly more physical force
is required to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
Both drivers should be familiar with the problems which might possibly occur while a vehicle is being towed. Unskilled drivers should not attempt to tow in
another vehicle or to be towed in.
The vehicle must be transported on a special breakdown vehicle or trailer if it
is not possible to tow in the vehicle in the way described or if the towing dis-
tance is greater than 50 km.
WARNING■ When towing, respect the national legal provisions, especially those
which relate to the identification of the towing vehicle and the vehicle be-
ing towed.■
When towing, exercise increased caution.
■
Spiral tow ropes must not be used for towing » Fig. 207- 
, the towing
eye may unscrew out of the vehicle - risk of accident.
■
The tow rope should not be twisted - risk of accident.
CAUTION■ Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter. The battery from another vehicle can be used as a jump-
start aid » page 220 , Jump-starting .■
If the gearbox no longer contains any oil, your vehicle must only be towed
with the front axle raised clear of the ground or on a breakdown vehicle or
trailer.
■
To protect both vehicles when tow-starting or towing, the tow rope should
be elastic. Thus one should only use plastic fibre rope or a rope made out of a
similarly elastic material.
■
There is always a risk of excessive stresses and damage resulting at the
points to which you attach the tow rope or tow bar when you attempt to tow a
vehicle which is not standing on a paved road.
■
Attach the tow rope or the tow bar to the towing eyes » page 222
or » page 223 to the detachable ball head of the towing equip-
ment » page 169 .
Note
We recommend using a tow rope from ŠKODA Original Accessories available
from a ŠKODA Partner.
