2015 SKODA OCTAVIA heater

Note■The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux.
heating, you must maintain the comfort temperature normally selected by you,
leave the fan switched on and leave the air outlet vents in open. It is recom-
mended to put the air flow in the position 
or 
.

CAUTION
■
The radio remote control comprises electronic components and must there-
fore be protected against water, severe impacts and direct sunlight.■
When the battery is fully charged, the range of the remote control is a few
hundred metres. Obstacles between the radio remote control and the vehicle,
bad weather conditions and a weaker battery can clearly reduce the range.
119Heating and ventilation

Fabric
Clean upholstery cover materials and cloth trims on doors, luggage compart-
ment cover, etc. using specific cleaning agents, e.g., dry foam.
Use a soft sponge, brush, or commercially available microfibre cloth.
Use a cloth and a cleaning agent specifically designed for this purpose to clean the roof trim.
Remove any lumps on the cover fabric and any fabric residue using a brush.
Remove stubborn hair using a “cleaning glove”.
Alcantara ®
Dust and dirt in pores, creases and seams may chafe and damage the surface.
Therefore, they must be removed regularly at short intervals with a cloth or
vacuum cleaner.
Minor changes in colour caused by use are normal.
CAUTION
■ For Alcantara ®
seat covers, do not use any solvents, floor wax, shoe cream,
stain remover, leather cleaners or similar agents.■
Avoid leaving the vehicle in bright sunlight for long periods of time in order
to stop the artificial leather, materials or Alcantara ®
from bleaching. During ex-
tended periods of standing outdoors, protect artificial leather, fabrics or Alcan-
tara ®
by covering.
■
Some clothing materials, e.g. dark denim, do not have sufficient colour fast-
ness. This can cause damage or clearly visible discolouration to seat covers,
even when used correctly. This applies particularly to light-coloured seat cov-
ers. This does not relate to a fault in the seat cover, but rather to poor colour
fastness of the clothing textiles.
Seat covers
Read and observe
and on page 187 first.
Electrically heated seats
Use a specific cleaning agent such as dry foam or similar to clean the covers. »
.
Seats without seat heating
Thoroughly vacuum the seat covers with a vacuum cleaner before cleaning.
Clean the seat covers with a damp cloth or cleaning products specially de-
signed for this purpose.
Indented points arising on the fabrics by everyday use, can be removed by
brushing against the direction of hair with a damp brush.
Always clean all parts of the covers, so that there are no visible edges. Then
allow the seat to dry completely.
CAUTION
■ Do not clean the covers of electrically heated seats either with water or with
other liquids - there is a risk of damaging the seat heating system.■
Regularly remove dust from the seat covers using a vacuum cleaner.
■
Electrically heated seats must not be dried after cleaning by switching on the
heater.
■
Do not sit on wet seats - risk of seat deformation.
■
Always clean the seats from “seam to seam”.
Safety belts
Read and observe
and on page 187 first.
Wash dirty seat belts with mild soapy water.
Remove coarse dirt with a soft brush.
WARNING■ The seat belts must not be removed for cleaning.■Never clean the seat belts chemically as chemical cleaning products could
destroy the fabric.■
The seat belts must not be allowed to come into contact with corrosive
liquids (e.g. acids).
■
The seat belts must be fully dried before being rolled up.
188General Maintenance

The coolant additive percentage in the coolant must be at least 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec-
essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir
» Fig. 207 on page 199 .WARNINGThe engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 194.■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container, safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
If coolant is swallowed, consult a doctor immediately.
■
Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■ If for some reason it is not possible to top up the coolant under the current
circumstances,  do not continue driving! Switch off the engine and seek as-
sistance from a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of engine damage, 
do not continue driving! Switch off the en-
gine and seek assistance from a specialist garage.
■
The amount of coolant additive in the coolant must never be allowed to be
less than 40 %.
■
Over 60 % of coolant additive in the coolant reduces the antifreeze protec-
tion and coolant effectiveness.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■ Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage.■
Do not fill the coolant above the mark
A
» Fig. 207 on page 199 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and venti-
lation), the coolant capacity is approx. 1 l larger.

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 201 first.
The vehicle's electrical system automatically prevents the battery from dis-
charging when the battery is being heavily used. 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.204General Maintenance

Some manual skills are required to change a bulb. For this reason, we recom-
mend having bulbs replaced by a specialist garage or seeking other expert help
in the event of any uncertainties.
▶ Switch off the ignition and the relevant lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
A stowage compartment for replacement bulbs is located in a plastic box in
the spare wheel or underneath the floor covering in the luggage compartment.
We recommend having the headlight settings checked by a specialist garage
after replacing a bulb in the low, high or fog beam.
In case of failure of a xenon gas discharge lamp or an LED diode, visit a special- ist garage.
WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 194.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H7 H8 and H15 are pressurised and may burst when changing the
bulb - risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Do not carry out any work on the Xenon gas discharge lamps - risk of
death!
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar. 230Do-it-yourself
