2009 SKODA ROOMSTER engine coolant

Heating and air conditioning system 90HeatingUsing the system
The heating system delivers air into the interior of the vehicle and
warms it as required.Setting temperature
– Turn the control dial ⇒fig. 115 to the right in order to increase the
temperature.
– Turn the control dial to the left in order to increase the tempera-
ture.
Controlling blower
– Turn the blower switch into one of the positions, 1 to 4, in order to
switch the blower on.
– Turn the blower switch into position 0 in order to switch the blower
off.
– Pressing button causes the recirculating air system ⇒ to be
switched on.Control for air distribution
– You can adjust the direction of the air flow using the air distribution
control ⇒page 89.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the heating and ventilation systems operate properly.
All controls apart from the control dial can be set to any desired intermediate
position.
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
The blower should aways be on to prevent the windows from misting up.
WARNING
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 acci-
dent increases. Switch recirculated air mode off as soon as the windows
begin misting up.
Note
•
If the air distribution is positioned towards the windows, the total amount of air
is used to defrost the windows and thus no air will be fed to the footwell. This can
lead to restriction of the heating comfort.
•
The used air streams out through the air removal openings in the luggage
compartment.
•
Have the air conditioning system cleaned by a specialist workshop.

Heating and air conditioning system 92Climatic (semi-automatic air conditioning system)*Description
Climatic is a combined cooling and heating system with electronic
control of the convenience temperature in the vehicle interior. It
makes it possible to optimally control the air temperature at any
season of the year.Description of the Climatic
It is important for your safety and for your driving comfort that the Climatic is oper-
ating properly.
The air conditioning system operates when switch ⇒page 93, fig. 116 is
pressed and the following conditions are met:•
engine running,
•
outside temperature above +2°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 the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculated 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 misting. Please familiarize yourself about
how to correctly operate the 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 the Climatic is operating which can only
be eliminated through considerable effort and expense (replacement of
compressor).

Technical Data
Using the air conditioning system economicallyThe compressor on the Climatic uses power from the engine when in cooling mode
which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the inte-
rior has been strongly heated through the effect of direct sunlight in order to allow
the heated air to escape.
The cooling system should not be switched on while travelling when the window is
open.
The desired interior temperature can also be achieved without switching in the
cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.Operational problemsIf the cooling system does not operate at outside temperatures higher than +2 °C,
there is a problem in the system. The reasons for this may be:•
The fuse of the Climatic is defective. Check the fuse, replace it if necessary
⇒page 218.
•
The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot ⇒page 19.
If you are not able to rectify the operational problem yourself, or if the cooling
capacity decreases, switch the cooling system off. Contact a specialist garage.
If there is a fault at the Climatronic, all symbols on the display flash after switching
on the ignition for 15 seconds. Contact a specialist garage.
Climatronic (automatic air conditioning)*Description
The Climatronic system is a combination of an automatic heating,
fresh air and cooling system which provides optimal comfort for the
occupants of the car.The Climatronic maintains a constant temperature fully automatically, once it has
been set. This is achieved by automatically varying the temperature of the
outflowing air, the blower stages and the air distribution. The system also takes into
account sunlight which eliminates the need to alter the settings manually. The
automatic mode ⇒page 97 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 +2°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
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 the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculated air mode in order to enhance the
cooling effect ⇒.
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 high coolant temperature in order to provide
cooling at a high load of the engine.

Technical Data
•
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 another vehicle as a jump-start aid ⇒page 213.
It is only possible to tow-start vehicles fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres ⇒page 216.
WARNING
•
Never run the engine in non ventilated 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 operated 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 operating temperature - risk of damaging the
engine!
•
Vehicles which are fitted with an exhaust gas catalytic 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 vehicle is standing. Drive off right away. When
driving 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 operate 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 seconds before repeating the attempt.
•
It is possible that the fuse on the electrical fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary ⇒page 218.
•
If the engine does not start, 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.
•
Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
•
It is possible that the fuse on the diesel preglow system is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒page 218.

Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after 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 switched off by turning the ignition key from posi-
tion into ⇒page 100, fig. 120.
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 for 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 for 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 185, “Working in the engine compartment”.
Shifting (manual gearbox)Shift into reverse only when the vehicle is stationary. Depress the clutch pedal and
hold it fully depressed. Wait 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 changing gears, in order to avoid unneces-
sary wear and damage.

Technical Data 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 55.
Detachable ball head
The ball rod is detachable on vehicles with towing device and suppliable from
Škoda original accessories. It is stowed together with separate fitting instructions in
the spare wheel well in the luggage compartment of the vehicle.
Note
•
We recommend that you also have your 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 temperature 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/h for safety reasons. This also applies for countries
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 accident
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 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 19.
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 189, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 32, “Coolant temperature/coolant
level ”.
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
