Canadian customers can contact an authorized Volkswagen dealer or Volkswagen Service Facility or call the Volkswagen Canada Customer CARE Center at 1-800-822-8987.
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 ⇒ fig. 19 or the power locking buttons ⇒ page 52, Unlocking or 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.

Synchronizing the remote control vehicle key

NOTICE
The door handle sensor surfaces can be activated by a strong stream of water or steam if a valid vehicle key is within range of the vehicle.
The door may not open if the outside and inside door handles are used at the same time.
If the vehicle battery or the battery in the remote control vehicle key is weak or dead, it might not be possible to unlock and lock the vehicle using Keyless Access. The vehicle can still be manually locked or unlocked with the key bit, Emergency closing and opening.
The driver message Key not in range appears in the instrument cluster display if there is no remote control vehicle key inside the vehicle or if the system does not recognize the remote control vehicle key. The key may not be recognized, for example, if it is covered by something that interferes with the signal (such as a briefcase), or if the remote control vehicle key battery is weak. Electronic devices such as mobile phones can also interfere with the signal.
Dirt on the door handles that contains a lot of salt (especially in winter) can affect the way the door handle sensors work. Cleaning the door handles can help with this problem, Exterior care and cleaning.
If the automatic transmission is not in Park (P) position, the electronic steering column lock will not lock and the vehicle will not lock via sensors in the front door handles or the remote control vehicle key.

Reactivating the one-touch feature
If the vehicle battery is disconnected or dead and the windows are not completely closed, the one-touch feature will not work and must be reactivated:
x Close all windows and doors.
x Insert the vehicle key into the door lock and turn and hold the key for more than 2 seconds in the direction of locking. See, Manually unlocking and locking the driver door.
x Release the key and then again turn and hold it in locking direction for more than 2 seconds. The one-touch feature is now reactivated.
The one-touch feature can be reactivated for one or more windows at the same time.
Convenience closing
The convenience closing feature lets you close the windows and the power sunroof from outside the vehicle as follows:
x Manual locking: lock the vehicle with the vehicle key bit in the driver door and keep the key turned in the locking position to close all windows and the power sunroof, Manually unlocking and locking the driver door.
Convenience closing first closes the windows and then the power sunroof.
WARNING
Improper use of power windows can result in serious personal injury.
x Never let anyone get in the way of a power window when closing it.
x When locking the vehicle from the outside, make sure that no one, especially children, remains in the vehicle. The windows will not open in case of an emergency.
x Always take the key with you when you leave the vehicle. You can still use the power windows for several minutes after the ignition is switched off as long as the driver or passenger door has not been opened.
NOTICE
The windows must go down slightly when you unlock the vehicle. Otherwise the windows and seals could be damaged when opening the doors.
If the power windows malfunction, the one-touch feature, as well as pinch protection may not work properly. See an authorized Volkswagen dealer or authorized Volkswagen Service Facility right away.
If convenience closing of the power windows requires removing the cover cap of the lock cylinder on the driver door, the cover cap must be reinstalled after the vehicle is locked, Manually unlocking and locking the driver door.

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 buildup 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.
Leaving the selector lever for a long period of time in any position other than Park (P) when the ignition is switched off can drain the vehicle battery.
On automatic transmission vehicles, the vehicle key can be removed from the ignition switch only when the transmission is in Park (P). You may have to press the release button on the transmission selector lever to put the lever into Park (P).
