2009 SKODA OCTAVIA TOUR coolant temperature

Heating and air conditioning system
86
The air conditioning only operates if button
⇒fig. 101
is pressed and the
following conditions are met:•
engine running,
•
outside temperature above +5 °C and
•
blower switch switched
on (positions 1 to 4).
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The wellbeing of the occupants of
the car is enhanced as a result of this
particularly at high outside temperatures and a high air humidity. The system prevents the windows misting up during the cold season of the year. The heating effect is dependent upon th
e coolant temperature, thus full heat
output only occurs when the engine
has reached its operating temperature.
It is possible to briefly activate recirc
ulated air mode in order to enhance the
cooling effect

.
Air at a temperature of about 5°C may flow
out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg area) and large differences in temperature, for example when getting out of
the vehicle, can result in chills in
sensitive persons. The air inlet in front of the windscreen must be free of ice, snow or leaves in order to ensure that the heating and cooling systems operate properly. After switching on the cooling
Condensation
from the evaporator of the air condi-
tioning may drip down and form a puddle
below the vehicle. This is quite normal
and not an indication of a leak!
WARNING
•
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin
g. Please familiarize yourself about
how to correctly operate th
e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.•
You should not leave recirculated air mode on over a longer period of
time, as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an
accident increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
•
We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the inte- rior of the vehicle forms deposits in the
evaporator of the air conditioning system.
This produces a permanent odour when th
e air conditioning system is operating
which can only be eliminated through co
nsiderable effort and expense (replace-
ment of compressor).Using the systemSetting temperature – Turn the control dial

Climatronic* (automatic air conditioning)Description The Climatronic system is a combin
ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the occupants of the car.The Climatronic maintains a constant temp
erature fully automatically, once it has
been set. This is achiev
ed by automatically varying the temperature of the
outflowing air, the blower stages and the ai
r distribution. The system also takes into
account bright sunlight which eliminates
the need to alter the settings manually.
The
automatic mode
⇒page 90 ensures maximum wellbeing of the occupants at
all times of the year. Description of Climatronic system The cooling operates only if the following conditions are met:•
engine running,
•
outside temperature above +5 °C,
•
the button is
not
pressed.
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The wellbeing of the occupants of
the car is enhanced as a result of this

.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to ensure that the heating and cooling systems operate properly. The AC compressor is switched off at a hi
gh coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling
Condensation
from the evaporator of the air condi-
tioning may drip down and form a puddle be

and not an indication of a leak! If you make a change before switching off
the ignition, which differs from the auto-
matic mode, the changed functions remain
stored. Only the function “circulating
air” is erased 20 minutes after switching off the ignition. Recommended setting for all periods of the year:•
Set the temperature to 22 °C (72 °F).

WARNING
•
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin
g. Please familiarize yourself about
how to correctly operate th
e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.•
You should not leave recirculated air mode on over a longer period of

Note
•
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of
deposits. Switch the cooling system on
at least once a month for approximately 5 mi
nutes at the highest blower stage - also
during the cold season of the year - in
order to remove such odours. Also open a
window for a short time.

. After the
windscreen has been demisted, press the button .Setting temperatureYou can set the interior temperature randomly with the buttons and
.
You can set the interior temperature between +18°C (64°F) and +29°C (84 °F). The interior temperature is regulated automatica
lly within this range. If you select the
temperature below +18°C (64 °F), “LO” appe
ars in the display. If you select the
temperature higher than +29°C (84 °F), “H
I” appears in the display. In both limit
positions the Climatronic operates at
maximum cooling or heating capacity,
respectively. The temperature is not controlled in this case. Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg area) and large differences in temperature, for example when getting out of the vehicle, can result in chills in sensitive persons.Controlling blower There are a total of six blower stages available.The Climatronic system controls the bl
ower stages automatically in line
with the interior temperature. You
can also, however, adapt the blower
stages manually to suit
your particular needs.

WARNING
•
“Stale air” may result in fatigue in
the driver and occupants, reduce
attention levels and also cause the windows to mist up. The risk of having an accident increases.•
Do not switch the Climatronic syst
em off for longer than necessary.
•
Switch the Climatronic system on as soon as the windows mist up.
Operational problemsIf all the symbols on the display of the au
tomatic air conditioning system flash for
approx. 15 seconds after switching on the ignition, then there is a fault in the system - visit a specialist garage. If the cooling system does not oper
ate, the following faults may exist:
•
the outside temperature is lower than +5°C,
•
The compressor of the automatic air
conditioning system was temporarily
switched off due to a too high temperature of the coolant,•
a blown fuse.
Check the fuse, replace it if necessary
⇒page 192. If a blown fuse is not the source
of the fault, switch the Climatronic off and have it checked. If the cooling capacity decreases, switch
the Climatronic off and have it checked.

Let go of the key as soon as the engine starts otherwise there may be damage
to the starter. The engine running noises may louder at
first be louder for
a short time after
starting the cold engine until oil pressure
can be built up in the hydraulic valve
clearance compensation. This is quite normal and is not an operating problem. If the engine does not start ... You can use the battery of anothe
r vehicle as a jump-start aid
⇒page 188.
It is only possible to tow-start vehicl
es fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres
⇒page 191.
WARNING
•
Never run the engine in non ventilat
ed or enclosed areas. The exhaust
gases of the engine contain besides
the odorless and colourless carbon
monoxide a poisonous gas - hazard! Carbon monoxide can cause uncon- sciousness and death.•
Never leave your vehicle unattended with the engine running.Caution
•
The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is immediately oper
ated after switching off the engine, the
starter or the engine can be damaged.•
Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper
ating temperature - risk of damaging the
engine!•
Vehicles which are fitted wi
th an exhaust gas catalyti
c converter should not be
tow-started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehi
cle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the pollutant emissions are lower.
Petrol enginesThese engines are fitted with a starter system which selects the correct fuel-air mixture for every external air temperature.•
Do
not depress
accelerator before and when starting engine.
•
Interrupt the attempt at starting after
10 seconds if the engine does not start
right awayand wait for about 30 se
conds before repeating the attempt.
•
It is possible that the fuse on the electric
al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary
⇒page 192.
•
Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is
very hot
, to slightly depress the accelerator
after the engine has started.Diesel enginesGlow plug system Diesel engines are equipped with a glow
plug system, the preglow period being
controlled automatically in
line with the coolant temperature and outside temper-
ature. The preglow indicator light
 comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating period otherwise the vehicle battery will be drained unnecessarily.•
You should start the engine immediately after the glow plug warning light

has gone out.•
The glow plug warning light will come on for about one second if the engine is
at a normal operating temperature or if the outside temperature is above +5°C. This means that you can start the engine
right away
.

Starting the engine after the fuel tank has run dry It may take longer than normal to start the
engine after refuelling
if the fuel tank has
run completely dry - up to one minute. This is because the fuel system must first of all be filled while the attempting to start the engine.Switching off the engine– The engine can be swit
ched off by turning the ignition key from posi-
tion into
⇒
page 94, fig. 105
.
WARNING
•
Never switch off the engine before the
vehicle is stationary - risk of acci-
dent!•
The brake booster only operates when the engine is running. Greater
physical effort for braking is required
when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.
Caution
you should not switch the engine off right
away at the end of your journey after the
engine has been operated fo
r a lengthy period at high
loads but should be allowed
it to run at idling speed for about 2 minutes
. This prevents any accumulation of heat
when the engine is switched off.
Note
•
The radiator fan may continue running fo
r a further 10 minutes or so after the
engine and the ignition have been switched
off. The coolant fan may, however, also
switch on again after some time if the coolant temperature rises because of an accumulation of heat in the engine or
if the engine is warm and the engine
compartment is additionally
heated by strong sunlight.
•
This is why particular care is required when carrying out any work in the engine
compartment
⇒page 160, “Working in the engine compartment”.
ShiftingShift into reverse only when the vehicle is
stationary. Depress the clutch pedal and
hold it fully depressed. Wa
it a moment before engaging reverse gear in order to
avoid any shift noises. The reversing lights will come on once reverse gear is engaged, provided the igni- tion is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•
One should not lay the hand on the shift lever while driving the vehicle. The
pressure of the hand will be transferred to
the gearshift forks in the gearbox. This
can, over a period of time, lead to
early wear of the gearshift forks.
•
Depress the clutch pedal fully when chan
ging gears, in order to avoid unneces-
sary wear and damage.

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 th
e aid of the headlight beam adjuster
⇒ page 51. Detachable ball head The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle. Further information on the towing device
⇒page 146.
Note
•
We recommend that you also have yo
ur vehicle inspected between service
intervals if you tow a trailer frequently.•
The handbrake on the towing vehicle
must be put on when coupling and
decoupling the trailer.Driving Tips Particular caution is required when towing a trailer.– 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 temper
ature gauge if the outside temper-
ature 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, particul
arly near accident
black spots. You must always reduce your speed immedi
ately 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 down-
hill 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 16.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce yo
ur speed immediately. Stop and switch off
the engine if the warning light
 in the instrument cluste
r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 165, “Inspecting the coolant level”. Please refer to the following guidelines
⇒page 30, “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 independent

You should also consult a doctor without delay if you have inadvertently
swallowed coolant.
Caution
Do not continue your journey if for some reason it is not possible under the conditions prevailing to top up with coolant. Switch the engine off
and obtain
professional assistance from a specialist garage, otherwise it could lead to severe engine damage.
For the sake of the environment
Do not re-use coolant if it is necessary to
drain the coolant in the system. It should
be collected and disposed of in comp
liance with environmental protection
regulations.Radiator fan The radiator fan may switch on suddenly.The radiator fan is driven by an electr
ic motor and controlled according to the
coolant temperature. The radiator fan may continue running fo
r up to 10 minutes after the engine has
been switched off - even if
the ignition is also off. It
may also switch on suddenly
after a certain time, if•
the coolant temperature has risen beca
use of an accumulation of heat or
•
the warm engine compartment is heated
up additionally by
strong sunlight.
WARNING
You must therefore be aware when work
ing in the engine compartment that
the fan may switch on suddenly - risk of injury!
Brake fluidInspecting the brake fluid levelThe brake fluid reservoir is located on the left of the engine compartment. The brake fluid reservoir on right-hand steering models is positioned on the other side of the engine compartment. – Switch the engine off.– Open the bonnet
⇒
in “Working in the engine compartment” on
page 160.
– Inspect the brake fluid level in the reservoir
⇒
fig. 155
. The level must
be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and automatic adjustment of the br
ake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level drops significantly within a short time or if it drops below the “MIN” marking. A situ- ation where the brake fluid level is too low is indicated by the warning light

lighting up in the instrument cluster
⇒page 34. In this case
stop immediately and
do not drive any further! Obtain professional assistance.
