Fig. 28 Keyless Access system: Sensor for unlocking A on the inside of the front door handles. Sensor for locking B on the outside of the front door handles.

The power locking system works 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.
The vehicle will lock again in a few seconds if you do not open one of the doors or the luggage com-partment lid.
Unlocking and opening doors (Keyless Entry)

x Open the door.
Closing and locking doors (Keyless Exit)
x Switch the ignition off.
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. 27 of the luggage compartment lid, it unlocks automatically when opened.
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 The most recently used vehicle key is inside the vehicle. All turn signals flash four times.
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 ⇒  Starting and stopping the engine. A key that was inside the vehicle when it was locked from the outside can be reactivated by pressing the

To use the convenience closing feature to close all power windows and the sunroof, hold your finger on the lock sensor surface on the outside of the door handle for a few seconds until the windows and sunroof close.
Remove your finger from the lock sensor surface ⇒ fig. 28 (B) to stop the function. If you touch the unlock sensor surface (A) on the inside of the door handle immediately after releasing the lock sensor surface (B), all of the windows will open (safety function).
Pinch protection is active during convenience closing of the windows and the power sunroof.
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.
x All windows may open if you turn the spray of water or steam away from and then back onto the door handle sensor surface in quick succession. If at least one power window is opened and the sensor is continuously activated, convenience closing is started.
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 ⇒  Manually unlocking and locking the driver door.
A driver message 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.
Anti-theft alarm system

The one-touch feature can be reactivated for one or more windows at the same time.

WARNING
Improper use of power windows can result in serious personal injury.

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 may not work properly. See an authorized Volkswagen dealer or authorized Volkswagen Service Facility right away.
If convenience closing of the power windows from the outside 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.

Daytime running lights (DRL)
Separate lamps are installed in the headlights or in the front bumper for the daytime running lights (DRL).
The daytime running lights are switched on whenever the ignition is switched on and the light switch is in position / or !54/.
When the daytime running lights are switched on, only these separate lamps come on ⇒ .
If the light switch is in position !54/, a low-light sensor switches the low beams as well as the instru-ment and switch lighting on and off automatically.
Daytime running lights (DRL) parking feature
Some models are equipped with a daytime running lights (DRL) parking feature that switches the daytime running lights off when the parking brake is engaged and the ignition is switched on.

Function Action
Switching the DRL off: – Switch the ignition on. – Turn the light switch to the / position. – Set the parking brake.
Switching the DRL back on: – Release the parking brake.

Static cornering lights
Your vehicle may have fog lights under the front bumper, which on some models are also static cor-nering lights. On some models the static cornering lights may 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 comes on; turn left and the left fog light comes on. 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. 80), 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/)
Your vehicle may be equipped with automatic headlights (!54/), which 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.
If the rain sensor recognizes rain and switches the windshield wipers on. If the windshield wipers have not moved for several minutes.

Leaving Home Action
Switch on: – Unlock the vehicle if the light switch is in the !54/ position and the low-light sensor registers darkness.
Switch off: – Automatically after preset delay period is over. – Lock the vehicle. – Turn the light switch to the / position. – Switch the ignition on.

The delay period can be adjusted in 10 second intervals and the function can be switched on and
off in the Lights & Vision menu ⇒  Volkswagen Information System.
If the Coming Home feature is switched on and the driver door is opened, no warning chime will sound to alert you that the lights are still on.
