Engine revolutions counter
First read and observe the introductory information and safety warn-ings
on page 9.
The red scale of the rev counter
1
» Fig. 2 on page 9 indicates the range in which
the system begins to limit the engine speed. The system automatically restricts
the engine speed to a steady limit.
You should shift into the next higher gear before the red scale of the revolution counter is reached, or select mode D on the automatic gearbox.
Follow the recommended gear to prevent engine speeds that are too high or too low » page 21 .
For the sake of the environment
Shifting to a higher gear in good time helps to lower fuel consumption, minimises
operating noise levels, protects the environment and contributes to a longer lifeand reliability of the engine.
Speedometer
First read and observe the introductory information and safety warn-
ings
on page 9.
7Warning against excessive speeds
An audible warning signal will sound when the vehicle speed exceeds 120 km/h 1)
.
The audible warning signal is switched off when the vehicle speed falls below
this speed limit.
Coolant temperature gauge display
First read and observe the introductory information and safety warn-
ings
on page 9.
The coolant temperature gauge
4
» Fig. 2 on page 9 operates only when the ig-
nition is switched on.
The following guidelines regarding the temperature ranges must be observed to avoid any damage to the engine:
Cold range
If the pointer is still in the left area of the scale it means that the engine has not
yet reached its operating temperature. Avoid high speeds, full throttle and high
engine loads.
The operating range
The engine has reached its operating temperature as soon as the pointer moves
into the mid-range of the scale, for a normal style of driving. The pointer may also
move further to the right at high engine loads and high outside temperatures.
CAUTION
Additional headlights and other attached components in front of the fresh air in-
let impair the cooling efficiency of the coolant. There is then a risk of the engine
overheating at high outside temperatures and high engine loads » page 15.

Heating and air conditioning system
Heating and air conditioning system
Introductory information
The heating effect is dependent upon the coolant temperature, thus full heat output only occurs when the engine has reached its operating temperature.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The well-being 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.
It is possible to briefly activate recirculated air mode to enhance the cooling ef-fect.
Please refer to the information regarding recirculated air mode for the air-condi- tioning system » page 85 or for Climatronic » page 87.
The air inlet in front of the windscreen must be free of e.g. ice, snow or leaves to ensure that the heating and cooling system operates 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 not a leak!
WARNINGFor 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 cor-
rectly operate the heating and ventilation systems, how to demist and defrost
the windows, as well as with the cooling mode.
Note
■ The used air streams out through the vents in the luggage compartment.■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 in-
terior of the vehicle forms deposits in the evaporator of the air conditioning sys- tem. This produces a permanent odour when the air conditioning system is oper-ating which can only be eliminated through considerable effort and expense (re-
placement of compressor).

Using the air conditioning system economically
The compressor on the air conditioning system 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 al-low the heated air to escape.
The cooling system should not be switched on while travelling when the window is open.
For the sake of the environment
Pollutant emissions are also reduced when fuel is saved » page 101, Economical
and environmentally friendly driving .
Operational problems
If 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.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 200 .
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 10.
If you are not able to resolve the operational fault yourself, or if the cooler output has reduced, switch off the cooling system and get assistance from a ŠKODA Spe- cialist garage.

›Press the button
 again, the warning light underneath the button goes out.
Recirculated air mode is switched off automatically if the air distribution controlC
» Fig. 85 on page 84 is turned to position . Recirculated air mode can be
switched on again from this setting by repeatedly pressing the button .
WARNINGDo not leave recirculated air mode on over a longer period of time, as “stale”
air can cause fatigue of the driver and passengers, reduce attention levels andalso cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up.

Climatronic (automatic air conditioning system)
Introductory information
The Climatronic in automatic mode ensures the best-possible setting of the tem-
perature of the outflowing air, the blower stage and air distribution.
The system also takes sunlight into account, which eliminates the need to alter
the settings manually.
Recommended setting for all periods of the year:
›
Set the desired temperature, we recommend 22 °C.
›
Press the button AUTO
» Fig. 86 on page 86.
›
Move the air outlet vents 3 and 4 » Fig. 82 on page 82 so that the air flow is
directed slightly upwards.
Cooling conditions
The cooling system only operates if the following conditions are met: › engine running;
› outside temperature above approx. +2 °C;
› 

» Fig. 86 on page 86 switched on.

ABC123SETUPDUAL86Using the system

›The engine is also preheated when the vehicle is stationary and the engine is
not running;
› It warms up the coolant by burning fuel from the vehicle tank. The coolant
warms up the air, which (if the blower speed is not set to zero) flows into the passenger compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).WARNING■ The auxiliary heating must never be operated in closed rooms - risk of poi-
soning!■
The auxiliary heating must not be running during refuelling - risk of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore, if you wish to operate the auxiliary heating, do not park the vehicle in such a way that the exhaust gases can come into contact with high-
ly flammable materials (e.g. dry grass) or easily inflammable substances (e.g.
spilt fuel).
CAUTION
■ The running auxiliary heater consumes fuel from the vehicle tank and automati-
cally controls the filling level. If only a low quantity of fuel is present in the fuel
tank, the function of the auxiliary heating is blocked.■
The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating and ventilation is running, the vehicle battery discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometres in order to recharge
the vehicle battery.
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 operating problem.
■
The air inlet in front of the windscreen must be free of e.g. ice, snow or leaves
to ensure that the auxiliary heating and cooling system operates properly.

» Fig. 99 on page 106 upwards before hitching
the trailer to the vehicle.
Safety eye
The purpose of the safety eye
2
» Fig. 99 on page 106 is to attach the break-
away cable of the trailer.
When attaching the breakaway cable to the safety eye, it must sag freely in all
trailer positions (sharp bends, in reverse, etc.).
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. The national legal
requirements must be observed.
Headlights
The headlight settings must be checked before starting a journey with a coupled
trailer. If necessary, adjust the settings with the headlight beam adjust-
ment » page 44 .
Driving speed
For safety reasons, do not drive faster than 80 km/h when hitching a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the trail- er is detected. Never attempt to stop the trailer from “swaying” by accelerating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first, then brake firmly. This will avoid brake jolts resulting from
the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as a
brake.
Trailer stabilisation
The trailer stabilisation is an extension of the stabilisation control that works in
conjunction with the counter-steering assistance to reduce the amount the trail-
er "sways".
After turning on the ignition, the ESC warning light  in the instrument cluster
lights up for about 2 seconds longer than the ABS warning light.
Prerequisites: › The towing device is assembled or retrofitted ex works;
› The ESC system is active. The warning light
 or  in the instrument cluster is
not illuminated;
› The trailer is electrically connected to the towing vehicle by means of the trailer
socket;
› The speed is higher than approx. 60 km/h;
› The trailer has a fixed drawbar;
› The ESC system works for both braked and unbraked trailers.
A trailer is connected to the anti-theft alarm system, when: › the vehicle is factory-fitted with an anti-theft alarm system and a towing de-
vice;
› the trailer is electrically connected to the towing vehicle by means of the trailer
socket;
› the electrical system of the vehicle and trailer is fully functional;
› the vehicle is locked with the car key and the anti-theft alarm system is activa-
ted.
When the vehicle is locked, the alarm is activated as soon as the electrical con-
nection to the trailer is interrupted.
Always switch off the anti-theft alarm system before a trailer is connected/dis- connected » page 35, Anti-theft alarm system .
Engine overheating
If the needle for the coolant temperature gauge moves into the right-hand area or the red area of the scale, the speed must be reduced immediately.
Stop and switch off the engine if the warning light 
in the instrument cluster
lights up. Wait a few minutes and check the level of coolant » page 174.
The following guidelines must be observed » page 15, Coolant temperature/cool-
ant level 
.
The coolant temperature can be reduced by switching on the heating. 110Using the system
