Fig. 26 Keyless Access locking and starting system: Sensor for unlocking A on the inside of the front door handles. Sensor for locking B on the outside of the door handles.

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, Starting and stopping the engine. A key that was inside the vehicle when it was locked from the outside is reactivated by pressing the 0 button on the deac-
tivated key ⇒ fig. 23.
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 a short time.
The door handle sensors become active again if one of the following events occurs:
x A short time has passed.
x OR: The vehicle is unlocked using the 0 button in the remote control vehicle key.
x OR: The luggage compartment lid is opened.
Convenience features
The settings in the Settings – Convenience menu, Volkswagen Information System determine which doors open when the door handle unlocking surface is grasped.
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.
Anti-theft alarm system

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 headlight
control (headlight switch in the AUT O position ⇒ fig. 83), they work only when the headlights have been automatically switched on. The static cornering lights do not come on when the headlight switch is in the O position or when the fog lights themselves have been switched on, Switching lights on and off.
Automatic headlight control (AUTO)
Automatic headlight control is a convenience feature only and cannot always recognize all lighting and driving situations.
If the light switch is in the AUT O 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.
Adaptive Front Lighting System (AFS)
The Adaptive Front Lighting System works only with the low beams switched on and only at speeds above about 6 mph (10 km/h). The swivel-mounted lamps automatically improve road illumination during cornering.
On vehicles equipped with the Adaptive Front Lighting System, the feature is switched on and off via the Assistants menu in the instrument cluster display, Volkswagen Information System .
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 headlight control (AUTO) is 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, the rear lights, and turn signals can temporarily fog up. This is normal and does not affect the service life of the vehicle's lighting system.
“Coming home” and “Leaving home” feature (orientation lighting)

“Coming home” Action
Switch on: – Switch off the ignition. – Operate the headlight flasher for about 1 second The “Coming home” lighting is switched on when the driver door is open. The delay period starts once the last vehicle door or the luggage compartment lid is closed.
Switch off: – Automatically after delay period is over. – Automatically, if a vehicle door or the luggage compartment lid is still open about 30 seconds after activation. – Turn light switch to the O position. – Switch the ignition on.

“Leaving home” Action
Switch on: – Unlock the vehicle if the light switch is in the AUT O 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 O position. – Switch the ignition on.
Background lighting in the outside mirrors
The background lighting in the outside mirrors illuminates the area near the doors when entering and exiting the vehicle. It is switched on when the vehicle is unlocked, a vehicle door is opened, or the “Coming home” or “Leaving home” feature is activated. If the vehicle is equipped with a light sensor, the background lighting in the outside mirrors is only switched on in darkness.
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.

NOTICE
x To help prevent damage to the engine hood and the windshield wiper arms, lift the wiper arms away from the windshield only when they are in the service position.
x Always carefully fold the windshield wiper arms down against the windshield before driving the vehicle.
Rain sensor

Fig. 90 Inside the front windshield above the inside mirror: Sensitive rain sensor surface.

Possible reasons for changes in the way the rain sensor works
The rain sensor may misread what is happening in the detection zone of its sensitive rain-sensor
surface ⇒ fig. 90 (arrow) and not work for a number of reasons, which include:
x Worn out wiper blades: Worn out wiper blades may leave a film of water or wiping streaks; this can cause the wipers to run longer, to wipe more often, or to wipe continuously at high speed.
x Insects: Insects hitting the sensor may trigger the wipers.
x Salt streaks: Salt streaks on the windshield from winter driving can cause wiping more often or continuously on glass that is almost dry.
x Dirt: Caked-on dust, wax, any other buildup on the windshield (lotus effect), or car-wash detergent residue can lower the rain sensor's sensitivity and cause it to react too slowly or not at all.
x Crack or chip in the windshield: If a stone hits and chips the windshield while the rain sensor is on, this will trigger a wiper cycle. After that, the rain sensor will recognize the change and recalibrate itself to respond to the sensitive surface's reduced detection zone. Depending on the size of the chip, the sensor's reaction pattern may or may not change.
WARNING
The rain sensor cannot always recognize rain and activate the wipers.
x Switch the wipers on manually when water on the windshield reduces visibility.
Clean the rain sensor's sensitive surface (arrow) regularly and check the wiper blades for wear or damage.
To remove wax and coats of polish safely, we recommend using an alcohol-based windshield cleaner.
