Auxiliary heating (parking heating)
The auxiliary heating (auxiliary heating) functions in connection with the air-con-
ditioning system or Climatronic.
It can be used when stationary, when the engine is switched off to preheat the
vehicle and while driving (e.g. during the heating phase of the engine).
The engine is also preheated, if the auxiliary heating is switched on when the ve-
hicle is stationary and the engine is switched off. This is not valid for vehicles with
the 3.6 l/191 kW
FSI engine.
The auxiliary heating (parking heating) warms up the coolant by combusting 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 from the auxiliary heating can
come into contact with highly flammable materials (e.g. dry grass) or easily in-
flammable substances (e.g. spilt fuel). Note
■ If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
The auxiliary heating automatically controls the filling level in the fuel tank. 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.
■ 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.
■ After switching off the auxiliary heating, the coolant pump runs for a short peri-
od.
■ The auxiliary heating and ventilation does not switch on or comes on, if the ve-
hicle battery indicates a low loading state » page 186, Automatic load deactiva-
tion .
■ The auxiliary heating (parking heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please re-
fuel! ■ The air inlet in front of the windscreen must be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
■ So that warm air can flow into the vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by
you, leave the fan switched on and leave the air outlet vents in an open position.
It is recommended to put the air flow in the position  or . Ð
100 Using the system

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 reaches its
operating temperature more rapidly and the pollutant emissions are lower. Note
■ The engine can only be started with a genuine ŠKODA key with the matching
code. ■ 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. ■ After switching off the ignition, the radiator fan can intermittently continue to
operate for approx. 10
minutes.
■ If the engine also does not start after the second attempt, the fuse for the elec-
tric fuel pump (petrol engines) or the control unit for the glow plug system or
glow plug system relay and fuel pump (diesel engine) could be faulty. Check the
fuse and replace, if necessary » page 207 or seek assistance from a

ŠKODA spe-
cialist garage.
■ We recommend locking the steering wheel whenever leaving the vehicle. This
acts as a deterrent against the attempted theft of your car. ÐAdjusting the steering wheel position
Fig. 112
Adjustable steering wheel: Lever below the steering wheel/safe
distance to the steering wheel
First read and observe the introductory information and safety warn-
ings on page 103.
The height and forward/back position of the steering wheel can be adjusted.
ä ›
First of all adjust the driver's seat
» page 66.
› Pull the lever below the steering wheel down
» Fig. 112 - .
› Adjust the steering wheel to the desired position (with regard to the height and
forward/back position).
› Push the lever upwards to the stop. Ð Electromechanical power steering
First read and observe the introductory information and safety warn-
ings on page 103.
The power steering enables you to steer the vehicle with less physical force.
With the electromechanical power steering, the steering assist is automatically
adapted to the speed and to the steering angle.
It is still possible to fully steer the vehicle if the power steering fails or if the en-
gine is not running (vehicle being towed in). However, greater physical effort is
required to turn the steering wheel.
If there is a fault in the power steering, the indicator light  or  lights up in the
instrument cluster » page 21. Ð Electronic immobiliser
First read and observe the introductory information and safety warn-
ings on page 103.
An electronic chip is integrated in the head of the key. The immobiliser is deacti-
vated 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 with-
drawn from the lock.
The engine will not start if a non-authorized ignition key is used.
The following is displayed in the information display: Immobilizer active. Ð

Introduction
This chapter contains information on the following subjects:
Refuelling 174
Unleaded petrol 175
Diesel fuel 176
The correct type of fuel for your vehicle and the tyre size and inflation pressure
are specified on the inside of the fuel filler flap » Fig. 155 on page 174 - . WARNING
The national legal requirements must be observed if carrying a spare canister
in the vehicle. We do not recommend carrying any fuel canisters in your vehi-
cle for safety reasons. In the event of an accident, the canister might be dam-
aged and fuel may leak out - risk of fire! CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring, which can result in considerable damage to parts of the en-
gine and exhaust system. ■ Immediately remove any fuel that has spilled onto the vehicle's paintwork - risk
of paint damage! Ð Refuelling

ings on page 174.
The filler flap is automatically unlocked or locked with the central locking.
Open fuel filler flap
›
Press in the middle of the left area of the fuel filler flap
» Fig. 155 -  .
› Unscrew the filler cap by turning it to the left and place the cap onto the top of
the fuel filler flap » Fig. 155 - .
Closing the filler cap
› Turn the filler cap to the right until it clicks into place.
› Close the fuel filler flap until it clicks into place.
Check that the fuel filler flap is closed properly. CAUTION
■ Before refuelling it is necessary to switch off the auxiliary heating system (aux-
iliary heating and ventilation).
■ The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Do not continue filling the
fuel tank otherwise the expansion volume is filled up. Note
The fuel tank has a capacity of about 60 litres, containing a reserve of approx.
10.5 litres . Ð
