NOTICE
The remote control vehicle keys contain electrical components. Protect them from damage, moisture and rough handling.
Do not press the buttons on the remote control vehicle key unless you actually want to use the function in question. Since terrain and conditions vary, pressing a button on the remote control vehicle key when it is not necessary may unlock the vehicle or set off the panic alarm, even if you think you are out of range.
Remote control vehicle key functions can be temporarily disrupted by interference from transmitters near the vehicle that use the same frequency range (such as radio equipment or mobile phones).
Things between the remote control vehicle key and vehicle, bad weather, as well as a weak battery can reduce the operating range.
If the remote control vehicle key buttons, Vehicle key set or the power locking buttons, Unlocking and locking the vehicle from the inside are pushed repeatedly in quick succession, the power locking system is switched off for a brief period to help keep it from being overloaded. The vehicle is then unlocked for about 30 seconds. Unless a door or the luggage compartment lid is opened in this span of time, the vehicle is automatically locked afterwards.

Volkswagen recommends having the battery in the remote control vehicle key changed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
The battery is on the back of the remote control vehicle key under a cover ⇒ fig. 30.
When changing the battery, pay attention to the correct polarity and use the same type of battery

Synchronizing the remote control vehicle key

Preparation for the anti-theft alarm system
If the vehicle is pre-equipped for installation of the anti-theft alarm system, the alarm system can be retrofitted by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
The anti-theft alarm system makes it more difficult for someone to break into or steal the vehicle.
The anti-theft alarm system is automatically activated when the vehicle is locked by pressing the lock button on the remote control vehicle key.
When is the alarm triggered?
The anti-theft alarm system sounds for about 30 seconds and the turn signals flash for up to 5 minutes if the following occurs with respect to the locked vehicle:
x Opening a door that has been mechanically unlocked without switching on the ignition within about 15 seconds.
x Forcibly opening a door.
x Forcibly opening the engine hood.
x Forcibly opening the luggage compartment lid.
x Switching on the ignition with an invalid key.
x Disconnecting the vehicle battery.
Deactivating the alarm
Unlock the vehicle with the unlock button on the remote control vehicle key and switch on the ignition with a valid vehicle key.
For vehicles with Keyless Access, the alarm can be deactivated by grasping one of the door handles when a valid remote control vehicle key is in range or by holding the remote control vehicle key to the right of the steering column trim and pressing the starter button, Unlocking and locking vehicles with Keyless Access.
After the alarm has stopped and the vehicle is opened again in the same or a different area that is protected by the alarm, the alarm is triggered again. For example, the alarm will sound again if the luggage compartment lid is opened after one of the doors has been opened.
The anti-theft alarm system is not activated when the vehicle is locked with the power lock switch 1 on the inside of the driver or front passenger doors.
If the driver door is mechanically unlocked using the vehicle key bit, only the driver door is unlocked, but not the entire vehicle. Switching on the ignition deactivates the anti-theft alarm system and activates the central locking button. To unlock the doors, use the central locking button or remote control vehicle key.
If the vehicle battery is dead or weak, the anti-theft alarm system will not work properly.

DANGER
20 mm button cells and other lithium batteries will cause serious personal injury and even death within a short time if swallowed.
x Always keep hand-held remote control devices with batteries, spare batteries, as well as dead button cell and larger 20 mm batteries out of the reach of children.
x Get medical attention immediately if you suspect that a battery has been swallowed.
WARNING
Improper use of the HomeLink® Universal Transmitter can cause serious or even fatal personal injury.
x Garage doors operate with enough force to cause serious personal injury.
x Never let anyone get in the way of a garage door when it is opening or closing.
x When programming the HomeLink® Universal Transmitter, you may be operating a garage door or estate gate. Always make sure that people and objects are out of the way to help prevent serious personal injury or property damage.
x When operating the “training” button on a garage door opener with a rolling code, you will need to stand on a ladder or step-stool. Always take extra precautions to prevent falls and serious injury.
x Never use the HomeLink® Universal Transmitter with any garage door opener that does not have the safety stop-and-reverse feature, as required by federal safety standards. This includes any garage door opener model manufactured before April 1, 1982.
x A garage door opener that cannot detect an object, signaling the door to stop and reverse, does not meet current federal safety standards. Using a garage door opener without these features increases the risk of serious injury or death.

WARNING
Improper use of vehicle keys can result in serious personal injury.
x Always take the key with you when you leave the vehicle. The engine can be started and vehicle systems such as the power windows can be operated, leading to serious personal injury.
x Never leave children, disabled persons, or anyone who cannot help themselves in the vehicle. The doors can be locked with the remote control vehicle key. This could result in people being trapped in the vehicle in an emergency. For example, depending on the time of year, people trapped in the vehicle can be exposed to very high or very low temperatures.
x Heat build-up in the passenger and luggage compartment of a parked vehicle can result in temperatures in the vehicle that are much higher than the outside temperatures, particularly in summer. Temperatures can quickly reach levels that can cause unconsciousness and death, particularly to small children.
x Never remove the key from the ignition switch while the vehicle is moving or rolling to a stop. The steering wheel will lock and you will not be able to steer or control the vehicle.
Leaving the key in the ignition for a long time when the engine is not running will drain the vehicle battery.
