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 cooling system prevents the windows from misting up when
outside temperatures are particularly low.
It is possible to briefly activate recirculated air mode to enhance the cooling
effect.
Please refer to the information regarding recirculated air mode for the air-con-
ditioning system » page 94 or for Climatronic » page 96.
WARNING■
For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting. Please familiarize yourself about
how to correctly operate the heating and ventilation systems, how to de-
mist and defrost the windows, as well as with the cooling mode.■
To reduce health risks (e.g. common colds), the following instructions for
the use of the cooling system are to be observed. ■The difference between the indoor temperature and the outdoor air
temperature should not be greater than about 5 ° C.
■ The cooling system is to be turned off about 10 minutes before the end
of the journey.
■ Once a year, a disinfection of the air conditioner or the Climatronic is to
be carried out by a specialist company.
CAUTION■ The air inlet in front of the windscreen must be free (e.g. of 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
conditioning may drip down and form a puddle below the vehicle. This is not a
leak.
Note
■ The exhaust air streams out through vents at the rear of the luggage com-
partment.■
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 evaporator of the air condition-
ing system. This produces a permanent odour when the air conditioning sys-
tem is operating which can only be eliminated through considerable effort and
expense (replacement of compressor).
Air outlets

Note
Do not cover the air outlet vents with objects of any kind.
Using the air conditioning system economically
Read and observe
and on page 90 first.
The air conditioning system compressor uses power from the engine when incooling mode, which will affect 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 if the windows are open.
For the sake of the environment
Pollutant emissions are also lower when fuel is being saved » page 113.Operational problems
Read and observe
and on page 90 first.
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 175 .
› The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot » page 31.
If you are not able to resolve the operational problem yourself, or if the cooler
output has reduced, switch off the cooling system and seek assistance from a
specialist garage.

WARNINGNever leave recirculated air mode on over a longer period of time, as “stale
air” can cause fatigue of the driver and the passengers, reduce attention
levels and also cause the windows to mist up. The risk of having an acci-
dent increases. Switch off recirculated air mode as soon as the windows
start to mist up.

The cooling system operates only if the following conditions are met. The cooling system is switched on » page 93.
The engine is running.
The outside temperature is above approximately +2 °C.
The blower switch is switched on (positions 1-4).
If the desired interior temperature can also be achieved without activating the
cooling system, fresh air mode should be selected.
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.
CAUTION
■ Under certain circumstances, air at a temperature of about 5 °C can flow out
of the vents when the cooling system is switched on.■
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when get-
ting out of the vehicle, can cause susceptible individuals to catch a cold.
Note
■ We recommend that you have the air conditioning system cleaned by a spe-
cialist garage once every year.■
During operation of the air conditioning, an increase in engine idle speed may
occur under certain circumstances in order to ensure sufficient heating com-
fort.

107
Switching off the engine
107
The engine can only be started using a correctly coded original key.
The engine running noises may louder at first be louder for a short time after starting the cold engine. This is quite normal and is not an operating problem.
WARNING■ When driving, the ignition key must always be in the position 2 » Fig. 107
on page 107 (ignition switched on) without the engine running. This posi-
tion is indicated by the warning lights coming on. If this is not the case, this
could result in unexpected locking of the steering wheel – risk of accident!■
Only pull the ignition key from the ignition lock when the vehicle has
come to a complete stop (by applying the handbrake). Otherwise, the steer- ing could be blocked – risk of accident!
■
Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!
■
Never leave the vehicle unattended with the engine running - there is
risk of accident, damage or theft!
■
Never switch off the engine before the vehicle is stationary – risk of acci-
dent!
WARNING■ Never (e.g. in garages) run the engine in a closed place - there is the dan-
ger of poisoning and death!■
Do not leave any items (e.g. cleaning cloths or tools) in the engine com-
partment. This presents a fire hazard and the risk of engine damage.
■
Never cover the engine with additional insulation material (e.g. with a
cover) – risk of fire!
CAUTION
■ The starter must only be operated when the engine is not running and the
vehicle is at a standstill. The starter or engine can be damaged if the starter is
activated when the engine is running 3
» Fig. 107 on page 107 .
■
If the engine does not start up after a second attempt, the fuse for the fuel
pump may have a fault. Check the fuse and replace if necessary » page 175, or
seek assistance from a specialist garage.
■
Let go of the ignition key as soon as the engine starts otherwise the starter
could be damaged.
■
Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter. The battery from another vehicle can be used as a jump-
start aid » page 172 , Jump-starting .
CAUTION
■
Avoid high engine revolutions, full throttle and high engine loads before the
engine has reached its operating temperature – risk of damaging the engine!■
Do not switch the engine off immediately at the end of your journey after the
engine has been operated over a prolonged period at high loads but leave it to
run at an idling speed for about 1 minute. This prevents any possible accumula-
tion of heat when the engine is switched off.
For the sake of the environment
Do not warm up the engine while the vehicle is stationary. If possible, start
your journey as soon as the engine has started. Through this the engine rea-
ches its operating temperature more rapidly and the pollutant emissions are
lower.
Note
After switching off the ignition, the radiator fan can intermittently continue to
operate for approx. 10 minutes.106Driving

Electronic immobilizerRead and observe
and on page 106 first.
An electronic chip is integrated in the head of the key. The immobiliser is deac-
tivated with the aid of this chip when the key is inserted in the ignition lock.
The electronic immobiliser is automatically activated when the ignition key is
withdrawn from the lock.
The engine will not start if a non-authorized ignition key is used.
The MAXI DOT display shows the following: Immobilizer active.

Brakes
Introduction
This chapter contains information on the following subjects:
Information on braking
108
Handbrake
109WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
The clutch pedal must be depressed when braking on a vehicle with man-
ual transmission, when the vehicle is in gear and at low revs. Otherwise,
the function of the brake booster may be impaired – risk of accident!
■
If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must
be ensured that the air supply to the front wheel brakes is not reduced.
The front brakes may overheat, which can have a negative impact on the
functioning of the braking system – there is a risk of an accident.
■
When leaving the vehicle, never leave persons who might, for example,
release the handbrake or take the vehicle out of gear unattended in the ve-
hicle. The vehicle could then start to move – risk of accident!
CAUTION
■ Observe the recommendations on the new brake pads » page 113.■Never let the brakes slip with light pressure on the pedal if braking is not
necessary. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.
Information on braking
Read and observe
and on page 108 first.
If the brakes are applied in full and the control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af- ter accelerating or driving off again.
Before travelling a long distance down a steep gradient, reduce speed and
shift into the next lowest gear. As a result, the braking effect of the engine will
be used, reducing the load on the brakes. Any additional braking should be
completed intermittently, not continuously.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv- ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
Under these severe conditions , the thickness of the brake pads must also be
checked by a specialist garage between services.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake
pads may be moist or have a coating of ice or layer of salt on them in winter.
The brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned and dried by applying the brakes several times.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that
the brake pedal can be depressed further, the brake system may be faulty.
Visit a specialist garage immediately and adjust your style of driving appropri-
ately as you will not know the exact extent of the damage.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The level of the brake fluid is monitored electronically » page 40,
 Brake sys-
tem .
Brake booster
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.108Driving

In the driver's footwell, only a footmat, which is attached to the two corre-
sponding attachment points, may be used.
Only use footmats from the range of ŠKODA Original Accessories, which are fit-
ted to two attachment points.WARNINGNo objects are allowed in the driver's footwell – risk of obstruction or limi-
tation in operating the pedals!

112WARNING■ Do not depress the accelerator if the forward driving mode is changed
when the vehicle is halted and the engine is running – there is a risk of an
accident.■
Never shift the selector lever to R or P modes when driving – there is a
risk of an accident.
■
The vehicle must be held on the brake pedal in D, S or R modes if the ve-
hicle is halted and the engine is running. Even when the engine is idling,
power transmission is never completely interrupted – the vehicle will creep.
CAUTION■ If the selector lever is shifted to N while the vehicle is being driven you must
lift off the accelerator pedal and you will need to wait until the engine has
reached its idling speed before shifting the selector lever to a forward driving
mode again.■
At temperatures below -10 °C, the engine can only be started in selector lev-
er position P.
■
Never try to hold the vehicle using the accelerator pedal when stopping on a
hill – this may lead to transmission damage.
