Remote control
Introductory information
You can use the remote control key to:
› unlock and lock the vehicle,
› unlocking boot lid;
› open and close the windows
» page 40, Window convenience operation .
The transmitter with the battery is housed in the handle of the remote control
key. The receiver is located in the interior of the vehicle. The operating range of
the remote control key is approx. 30 m. But this range of the remote control can
be reduced if the batteries are weak.
The key has a fold-open key bit which can be used for unlocking and locking the
car manually and also for starting the engine.
The spare key must by initialised by a ŠKODA partner after the receiver unit is re-
paired or replaced. Only then can the remote control key be used again.
Note
■ The operation of the remote control may temporarily be affected by interfer-
ence from transmitters close to the car and which operate in the same frequency
range (e.g. mobile phone, TV transmitter).■
The battery must be replaced if the central locking or anti-theft alarm system
does react to the remote control at less than approx. 3 metres away » page 28.

the battery in the remote control key was replaced.
This means it is necessary to synchronise the key as follows:
› press any button on the remote control key;
› pressing of the button means that the door will unlock with the key within 1 mi-
nute.

On vehicles fitted with automatic gearbox, the selector lever must be moved into the position P before unlocking.
The KESSY system can find the valid key, even if it was left in the front of the ve-
hicle's roof for example
D
» Fig. 15 . It is therefore not always necessary to know
where the key is.
Always check to see whether the vehicle is locked.
CAUTION
■ After leaving the vehicle, it does not lock automatically, the procedure for lock-
ing the vehicle must therefore be observed.■
Do not use gloves or other objects which might prevent direct contact between
the hand and the sensor.
Note
■ If the battery in the key is weak or discharged, the vehicle may not be unlocked
or locked via the KESSY system. In this case, use the emergency unlocking or emergency locking on the driver's door » page 36.ABCProtection against inadvertently locking the key in the vehicle
If the key which was used to lock the vehicle including the boot lid, remains in the
vehicle, the protection mechanism against inadvertently locking the key in the ve-
hicle is activated and the vehicle unlocks itself again D
» Fig. 15 on page 33.
The turn signal lights flash four times as confirmation that the vehicle has been
unlocked again.
The following message is displayed in the information display or display of the in-
strument cluster: Key in vehicle. or KEY IN VEHICLE .
Additionally, on vehicles which are fitted with the anti-theft alarm system, an au- dible signal sounds.

engine is running or when no key was found in the vehicle. This can occur if the
key is outside the vehicle, the battery in the key is discharged, the key is defec-
tive or the electromagnetic field is strongly disturbed. Some electronic devices,
e.g. mobile phones, can also cause faults.

Operational faults in the automatic power windows
First read and observe the introductory information and safety warn-
ings
on page 38.
The automatic power windows do not work if the vehicle battery was disconnec-
ted and connected while a window is open. The system must be activated.
Proceed as follows in order to re-establish the function:
›
Switch on the ignition.
