Unlocking and locking vehicles with Keyless Access

Fig. 40 Ranges of the Keyless Access with push button start. Outside the vehicle: Unlocking range. Inside the vehicle: Starting range.

Fig. 41 Keyless Access with push button start: Sensor for unlocking A on the inside of the front door handles. Sensor for locking B on the outside of the front door handles.

x Keyless Exit: Locking the vehicle via the door handle sensor on the driver or front passenger door (B).
The power locks and the closing system work like the standard unlocking and locking system. Only the way that the systems are operated is different.
All turn signals flash twice to confirm that the vehicle has been unlocked and once to confirm that it has been locked.
If the vehicle was unlocked and within the next few seconds no door or the luggage compartment lid has been opened, the vehicle is automatically locked again.
Unlocking and opening doors (Keyless Entry)
x Grasp the door handle of the driver or front passenger door so that you touch the unlocking sensor surface (A).
x Open the door.
Closing and locking doors (Keyless Exit)
x Close the driver door.
x Touch the sensor surface in the door handle on the driver or front passenger door (B). The vehicle is locked. The door being locked must be closed.
Unlocking and locking the luggage compartment lid
If the vehicle is locked and a valid remote control vehicle key is within range ⇒ fig. 40 of the luggage compartment lid, it unlocks automatically when opened.
x Open and close the luggage compartment lid as you would a standard luggage compartment lid ⇒  Luggage compartment lid.
The luggage compartment lid locks automatically when it is closed except in the following situations:
x The vehicle is completely unlocked.
x When an authorized remote control vehicle key is inside the vehicle.
Locking with a second vehicle key
If a remote control vehicle key is inside the passenger compartment, the vehicle can be locked from the outside only if a second valid remote control vehicle key is within range.
When the vehicle is locked from the outside, the keyless go (starting) function of any keys left in the passenger compartment will be deactivated. All other functions (remote central locking and unlocking as well as emergency starting) remain active and unchanged.
A key that was inside the vehicle when it was locked from the outside is reactivated:
x by pressing a button on the deactivated key.
x by pressing a door handle sensor when the deactivated key is outside of the vehicle, but within range.
x by starting the engine with the starter button on the center console (but not by starting the engine
with the remote start button on a key that is outside of the vehicle ⇒  Remote start feature).
Automatic deactivation of sensors
If the vehicle has not been unlocked or locked for a longer period of time, the proximity sensors in the passenger door are automatically deactivated.
If a sensor on the door handle of a locked vehicle is activated too often, for instance by a bush or hedge that rubs against the vehicle, the sensors in the door handle on that side of the vehicle are switched off for about 30 minutes.
The door handle sensors become active again if one of the following events occurs:
x 30 minutes have passed.
x OR: The vehicle is unlocked using the 0 button in the remote control vehicle key.

x Remove the cover cap from the concealed lock cylinder on the driver door ⇒  Manually unlocking and locking the driver door.
x Turn the vehicle key bit in the lock of the driver door to the closing position and hold it there ⇒  Power locking system. The power sunroof now closes. Release the vehicle key in order to stop the process.
x On vehicles with Keyless Access, using the door handle sensors ⇒  Power locking system.
Convenience closing first closes the windows and then the power sunroof. All turn signals blink once to confirm that the windows and power sunroof are closed.
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 win-dows for several minutes after the ignition is switched off as long as the driver or front pas-senger door has not been opened.
x Always use the safety switch when children are in the back seat to disable the rear power windows and keep them from being opened and closed.
If the power windows malfunction, the one-touch feature, as well as pinch protection will not work properly. See an authorized Volkswagen dealer or authorized Volkswagen Service Facility right away.
Power window pinch protection

Static cornering lights
Your vehicle may have fog lights under the front bumper that are also static cornering lights. On some models the static cornering lights may also be integrated in the headlights. At speeds below about 25 mph (40 km/h), the light on one side of the vehicle will come on automatically when you turn a corner. If you turn to the right, the right fog light lights up; turn left and the left fog light lights up. The light dims and goes out when the steering wheel is straightened out again.
When you move the selector lever to Reverse (R), the static cornering lights on both sides of the vehicle may come on so that you can see the area around the vehicle better when backing up.
The static cornering lights work only when the headlights are on. If you are using automatic headlights
(headlight switch in the !54/ position ⇒ fig. 101), they work only when the headlights have been auto-matically switched on. The static cornering lights do not come on when the headlight switch is in the /
position or when the fog lights themselves have been switched on ⇒  Switching lights on and off.
Automatic headlights (!54/)
Automatic headlights are a convenience feature only and cannot always recognize all lighting and driving situations.
If the light switch is in the !54/ position, both vehicle lighting and instrument and switch lighting are
automatically switched on and off in the following situations ⇒ :

Automatic activation: Automatic deactivation:
If the low-light sensor registers darkness, for example when driving through a tunnel. If sufficient brightness is registered.

WARNING
Crashes and other accidents can happen when you cannot see the road ahead and when you cannot be seen by other motorists.
x Never use daytime running lights (DRL) to see where you are going. DRL are not bright enough to light up the roadway and be seen by other motorists. You will not be able to see far enough ahead for safety, especially at dusk or when it is dark. Always switch on the low-beam headlights at dusk or when it is dark.
x The taillights do not come on when the daytime running lights are switched on. A vehicle without taillights on cannot be seen by others in bad weather, at dusk, or when it is dark.
x If automatic headlights (!54/) are switched on, the low-beam headlights still may not be switched on in fog or heavy rain. You have to switch on the low-beam headlights yourself.
In cool or humid weather, the insides of the headlights, rear lights, and turn signals can tempo-rarily fog up. This is normal and does not affect the service life of the vehicle's lighting system.
