Introduction
Vehicle key
The key can be used to lock and unlock the car from a distance ⇒ Central locking system.
The remote control transmitter and the battery are integrated in the key. The receiver is located in
the vehicle interior. The remote control range is several metres around the vehicle when the battery
is fully charged.
If the vehicle cannot be opened and closed using the vehicle key, the vehicle key will have to be re-
synchronised ⇒ Synchronising the vehicle key, or the battery in the key replaced ⇒ Replacing the
battery.
Several vehicle keys can be used.
Opening and closing the key bit
Press button ⇒ Fig. 16① to release the key bit and open it.
To fold in, press button ① and simultaneously fold in the key bit until it clicks into place.
Swallowing batteries with a diameter of 20 mm or other lithium batteries can result in severe
or even fatal injuries within a very short period of time.
•Always keep the vehicle key, key ring with batteries, spare batteries, round cells and other
batteries that are larger than 20 mm out of the reach of children.
•Call for medical help immediately you suspect that someone has swallowed a battery.
DANGER
Improper or unsupervised use of the vehicle key can lead to accidents or injuries.
•Always take all vehicle keys with you every time you leave the vehicle. Children or
unauthorised persons could lock the doors and tailgate, start the engine, switch on the
ignition and thus operate electrical equipment, such as the electric windows.
•Never leave children or people requiring assistance alone in the vehicle. They could
become trapped in the vehicle in an emergency and may not be able to get themselves to
safety. For example, locked vehicles may be subjected to very high or very low
temperatures, according to season. This can cause serious injuries and illness or
fatalities, especially for small children.
•Never remove the vehicle key from the ignition lock when the vehicle is in motion. The
steering lock may be activated and you will no longer be able to steer the vehicle.
WARNING

Replacement key
You will need to quote the vehicle chassis number when ordering a replacement key or additional
remote control keys.
Every new key contains a microchip which must be encoded with the data for the vehicle's
electronic immobilizer. The vehicle key will not work if it is not fitted with a microchip, or if the
microchip has not been encoded. The same goes for keys that have been cut to fit the vehicle.
New keys or replacement keys are available from Volkswagen dealerships or from qualified
workshops and authorised key services that are qualified to manufacture these vehicle keys.
New and replacement vehicle keys must be synchronised before use. Proceed to a qualified
workshop.
Press the buttons on the key only if the corresponding function is actually needed. Pressing
a button when the function is not required could lead to the vehicle being unlocked unintentionally
or the alarm going off. This also applies even when you are not within the effective range.
The function of the vehicle key can be affected temporarily if there is more than one
transmitter in the direct vicinity working on the same frequency (e.g. a two-way radio or mobile
telephone).
Obstacles between the key and the vehicle, bad weather conditions and weak batteries can
reduce the range of the remote control.
If the buttons on the vehicle key ⇒ Fig. 16 or one of the central locking buttons ⇒ Central
locking system are pressed repeatedly within a short period of time, the central locking system will
switch off briefly to prevent overloading. The vehicle will then be unlocked. Lock the vehicle if
necessary.

microchip has not been encoded. The same goes for keys that have been cut to fit the vehicle.
New keys or replacement keys are available from Volkswagen dealerships or from qualified
workshops and authorised key services that are qualified to manufacture these vehicle keys.
New and replacement vehicle keys must be synchronised before use. Proceed to a qualified
workshop.
Indicator lamp in the vehicle key
Every vehicle key contains electronic components. Protect the key from damage, moisture
and excessive vibration.

If a button on the vehicle key is pressed briefly, the indicator lamp ⇒ Fig. 18 (arrow) flashes once.
The lamp will flash several times if the button is pressed and held, e.g. convenience closing of the
electric panorama sliding/tilting glass roof.
If the indicator lamp in the key does not light up when a button is pressed, the battery in the key
should be replaced ⇒ Replacing the battery.

Synchronising the vehicle key
First read and observe the introductoryinformation and safety warnings⇒
Introduction
It may no longer be possible to lock or unlock the vehicle with the remote control if the  button
is pressed repeatedly outside of the effective range of the vehicle key. If this is the case, the vehicle
key should be re-synchronised as follows:
•Fold out the key bit of the vehicle key ⇒ Opening and closing the key bit.
•The vehicle key can be damaged if the battery is not changed properly.
•Unsuitable batteries can damage the vehicle key. Discharged batteries should only be
replaced with new batteries of the same voltage rating, size and specification.
•Ensure that the battery is fitted the right way round.
NOTICE

•Press the  button on the vehicle key. Remain standing close to the vehicle.
•Unlock the vehicle with the key bit within one minute. The synchronisation process is complete.
Central locking system
 Introduction
This chapter contains information on the followingsubjects:
⇒ Description of the central locking system
⇒ Locking or unlocking the vehicle from outside
⇒ Locking or unlocking the vehicle from the inside
⇒ SAFELOCK mechanism
The central locking system will only work correctly when all doors and the tailgate are properly
closed. The vehicle cannot be locked with the key if the driver door is open.
If the vehicle is unlocked and not used for a long time (e.g. in your own garage) the vehicle battery
could discharge or the engine may not start.

Description of the central locking system
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The central locking system enables you to lock and unlock all doors and the tailgate from one point:
•From outside the vehicle with the vehicle key ⇒ Locking or unlocking the vehicle from outside.
•From inside the vehicle with the central locking button ⇒ Locking or unlocking the vehicle from
the inside.
Certain functions for the central locking system can be activated or deactivated by a qualified
workshop.
The doors and the tailgate can be locked or unlocked manually if the vehicle key or central locking
system fails.
Locking the vehicle after the airbags have been triggered
The entire vehicle is unlocked if the airbags are activated during an accident. After an accident, the
vehicle can be locked by one of the methods below, depending on the damage incurred.
FunctionAction
Locking the vehicle with the
central locking button.
– Switch off the ignition.
– Open one of the vehicle doors once.
– Press the central locking button .
Locking the vehicle using the
vehicle key.
– Switch off the ignition.
OR: remove the key from the ignition lock.
– Open one of the vehicle doors once.
– Lock the vehicle with the vehicle key.
Improper use of the central locking system could lead to serious injury.
•The central locking system locks all doors. Locking the vehicle from the inside may
prevent the doors from being opened unintentionally and unauthorised persons from
entering the vehicle. However, locked doors can delay assistance to passengers inside
the vehicle in the event of an accident or emergency.
•Never leave children or people requiring assistance alone in the vehicle. All doors can be
locked from the inside using the central locking button. This may mean that people lock
themselves in the vehicle. People locked in the vehicle may be subjected to very high or
very low temperatures.
•Temperatures inside a locked vehicle may reach extremes of heat or cold, according to
season. This can cause serious injuries and illness or fatalities, especially for small
children.
•Never leave anyone inside a locked vehicle. People in the vehicle could become trapped
in an emergency and may not be able to get themselves to safety.
WARNING

If the buttons on the vehicle key ⇒ Fig. 21 or one of the central locking buttons ⇒ Fig. 23 are
pressed repeatedly within a short period of time, the central locking system will switch off briefly to
prevent overloading. The vehicle is then unlocked for approximately 30 seconds. If the doors or the
tailgate are not opened during this time the vehicle will lock again automatically.
