2010 SKODA ROOMSTER cooling

Heating and air conditioning system
84
Using the air conditioning system economicallyThe compressor on the Climatic uses powe r 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 interior
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 malfunctionsIf the cooling system does not operate at outside temperatures higher than +5 °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 191.

The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot page 16.
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.
Climatronic* (automatic air conditioning)Description
The Climatronic system is a combinat ion of an automatic heating, fresh
air and cooling system which provides optimal comfort for the occu-
pants of the car.The Climatronic maintains a constant temperat ure 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 86 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 approx. +2°C,

switched on.
If the cooling system is switched on, th e temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this partic-
ularly 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 recirculat ed 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.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!AC

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

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 minut es 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.

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 interior
of the vehicle forms deposits in the evapor ator of the air conditioning system. This
produces a permanent odour when the air co nditioning system is operating which can
only be eliminated through considerable effort and expense (replacement of
compressor).

Setting temperature– You can set the desired interior temperature after switching on the ignition with the
control dial .
You can set the interior temperature betw een +18°C (64°F) and +29°C (86 °F). The
interior temperature is regulated automatica lly within this range. If you select the
temperature below +18°C (64°F), “LO” appears in the display. If you select the temper-
ature higher than +29°C (86°F), “HI” appears in the display. In both limit positions the
Climatronic operates at ma ximum 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 seven blower stages available.The Climatronic system controls the blower st ages automatically in line with the inte-
rior temperature. You can also, however, adap t the blower stages manually to suit your
particular needs.
– Turn the control dial  page 85, fig. 90 to the left (reduce blower speed) or right
(increase blower speed).
If you switch off the blower, th e Climatronic is switched off.
WARNING

“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident
increases.

Do not switch the Climatronic system off for longer than necessary.

Switch the Climatronic system on as soon as the windows mist up.

Towing a trailer
148
Towing a trailerTo w i n g a t r a i l e rTechnical requirements
The towing device must satisfy certain technical requirements.Your vehicle is designed primarily for tr ansporting persons and luggage. It can,
however, also be used for towing a traile r - provided certain technical equipment is
fitted.
If your vehicle has been equipped with a towing device from Škoda Original Accesso-
ries, then the towing device satisfies all technical and legal requirements.
Your vehicle is fitted with a 13-pin power socket for the electrical connection between
the vehicle and trailer. If the tr ailer which you wish to tow has a 7-pin connector, you
can use a suitable adapter
13) from Škoda original accessories.
This work must be carried out in accordance with the manufacturer's specifications if
a towing device is retrofitted.
Specialist garages are familiar with details re lating to retrofitting a towing device and
for any necessary modifications to the cooling system.
WARNING
We recommend that you have the towing device from Škoda original accesso-
ries installed by a specialist garage. 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
There are a number of points to pay attention to when towing a trailer.Trailer load
The permissible trailer load must on no account be exceeded. You can negotiate appropriately steeper inclin
es and descents if you do not make full
use of the permissible trailer load.
The trailer loads specified only apply for altitudes up to 1 000 metres above mean sea
level. On petrol engines without forced indu ction, the engine power output drops with
increasing height due to a lowering of air pr essure and thus the ability to climb, this
means that the trailer load must be reduced by 10% for every further increase of 1 000
metres in height above sea le vel. The towed weight is the weight of the (laden) vehicle
and the (laden) trailer together. One should ta ke this into account before driving up to
higher altitudes. Petrol engines with forced induction use an air pressure correction
method, so that their power output does not depend on the height above sea level.
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 docu-
ments.
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 th e items to prevent them slipping.
Tyre pressure
Correct the tyre inflation pressure on yo ur vehicle for that of “fully laden”, page 173.
The inflation pressure of the tyres fitted to the trailer adjust in accordance with the
manufacturer's recommendation.
Exterior mirrors
You have to have additional ex terior 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, al so check the setting of the headlights. Alter
the setting as necessary with the aid of the headlight beam adjuster page 49.13)In some countries the adapter is supplied with the towing device.s16g.4.book Page 148 Wednesda y, February 10, 2010 3:53 PM

Detachable ball head
The ball rod is detachable on vehicles with towing devi
ce 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 inter-
vals if you tow a trailer frequently.

The handbrake on the towing vehicle must be put on when coupling and decou-
pling 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 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 combina-
tion.
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 allo wed speed should not be used when there
are unfavourable road, weather or wind cond itions, particularly near accident black
spots. You must always reduce your speed immediat
ely 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 engi ne 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 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 166,
“Inspecting the coolant level”.
Please refer to the following guidelines  page 28, “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 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 th e slope without any drop in speed.

Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!There is a risk of injuries, scalding, acci dents and fire when working in the engine
compartment, e.g. inspecting and replenishing oil and other fluids. For this
reason, it is essential to comply with the warning instructions stated below and
with the general applicable rules of safe ty. The engine compartment of your car
is a hazardous area  .
WARNING

Never open the bonnet if you see that steam or coolant is flowing out of the
engine compartment - risk of scalding! Wait long enough until the steam or
coolant has stopped escaping.

Switch off the engine and pull out the ignition key.

Apply the handbrake firmly.

If your vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if it is fitted with automatic gearbox, move the selector lever into
position P.

Allow the engine to cool down.

Keep children clear of the engine compartment.

Do not touch any hot engine parts - risk of burns!

Never spill oil and other fluids over the hot engine. Such fluids (e.g. the anti-
freeze contained in the wash liquid) may ignite!

Avoid short circuits in the electrical system - particularly on the battery.

Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!

Never open the cap of the coolant expans ion bottle as long as the engine is
still warm. The cooling system is pressurized!

Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your face, hands and arms from hot steam or
hot coolant.

Do not let objects, such as e.g cleaning cloth or tools lie in the engine
compartment.

If you wish to work under the vehicl e, 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!

In cases where it be necessary to carry out inspection work when the engine
is running there is an additional risk fr om rotating parts (e.g. the V-ribbed belt,
alternator, radiator fan) and from the high-voltage ignition system. Please
observe in addition the following:
Never touch the electrical cabl es of the ignition system.
 Absolutely avoid any jewellery, loose it ems of clothing or long hair from
getting into the rotating parts of the engine - Hazard! Therefore remove any
jewellery beforehand, tie up your hair and wear tight fitting clothing.

Please also comply with the warnin g instructions stated below when
carrying out any essential work on the fuel system or on th e electrical system:
 Always separate the car battery from the electrical system.
 Do not smoke.
 Never carry out any work close to naked flames.
 Always keep a working fire extinguisher at hand.Caution
When replenishing fluids in the engine, always ensure that the fluids are on no account
mixed up. This may result in major oper ating problems and also vehicle damage!

Caution
You must not pour any additives into the en gine oil - risk of engine damage! Damage,
which results from such product, are excluded from the warranty.
For the sake of the environment

You must on no account pour oil into the ground or into the sewage system.

In view of the problems involved in prop erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by an authorised Škoda Service Partner.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating condi-
tions. The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture not only provides antifreeze protection down to -25°C but also protects
the cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the coolant by
adding water, also not during the summer mo nths or in countries with a warm climate.
The concentration of coolant additive in the coolant must be at least 40%.
You can increase the amount of antifreeze in the coolant if a higher concentration of
antifreeze is necessary for climatic reasons but only up to 60% (antifreeze protection
down to approx. -40°C). The antifreeze prot ection tails off above that concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland) are
already factory-filled with a coolant which offers antifreeze protection down to about
-35°C. In these countries the concentration of coolant additive should be at least 50%. Coolant
The cooling system is factory-
filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the antifr eeze agent G13 (purple in colour).
We recommend that you contact a specialist garage if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
A specialist garage can also supply you with the correct coolant additives.
Coolant capacity
Caution

Other coolant additives may cause operational problems which, in particular,
involves significantly reduci ng the anticorrosion effect.

Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequenc e of this, result in major engine damage.Petrol engines

Inspecting and replenishing
166
Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet  in “Working in the engine compartment” on page 162.
– Check the level of coolant in the coolant expansion bottle fig. 138 . The coolant
level when the engine is cold must lie between the “MIN” and “MAX” mark-
ings. The level may also rise slightly above the “MAX” marking when the engine is
warm.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in
the instrument cluster
  page 28. We nevertheless recommend inspecting the
coolant level directly at the reservoir from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You should
not merely top up the coolant in the reservoir. It is also important to have the cooling
system inspected without delay by a specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant expansion
bottle which is completely free of leaks if the coolant boils as a result of overheating
and is forced out of the cooling system.
WARNING
Read and observe the warning notes page 162, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as s oon as possible if the source of overheating
itself cannot be determined and removed, since there may be grave damage to the
engine.Replenishing the coolant– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir fig. 138 and
unscrew the cap carefully by turning it to the left .
–Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one specific
specification page 165, “Coolant”. Do not use an al ternative additive if the coolant
additive G12 PLUS - PLUS is not available in exceptional cases. Just top up the system
with water and as soon as possible arrange adjustment to correct the mixing ratio of
water and coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant which is heated up is forced out
of the cooling system through the pressure relief valve in the cap of the coolant
compensation bottle.
Wait until the engine has cooled down for a system which has suffered a major loss of
coolant before pouring in coolant. This is necessary to avoid engine damage.
WARNING

The cooling system is pressurized! Do not open the cap of the coolant
expansion bottle if the engine is still hot - risk of scalding!

The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the health.
It is important, therefore, to always safely store any coolant additive in its orig-
inal container out of the reach of children - risk of poisoning!
