There is a fault in the locking system.
Go to a qualified workshop. Volkswagen recommends using a Volkswagen dealership for this
purpose.
Turn signals do not flash
If the turn signals do not flash as confirmation when the vehicle is locked:
At least one of the doors or the boot lid is not closed.
OR: convenience closing is in progress and not all windows and the glass roof have been closed.
Vehicle locks itself automatically
The vehicle will lock itself again automatically after approx. 45 seconds if one of the following
conditions applies:
The vehicle has been unlocked but not opened.
The ignition has not been switched on.
The boot lid has not been opened.
The vehicle has been unlocked using the lock cylinder.
The vehicle has been locked using the central locking button in the vehicle interior.
Response when locking the vehicle with a second vehicle key
Keyless Access: the vehicle key located inside the vehicle will be blocked from starting the engine if
the vehicle has been locked from the outside using a second vehicle key. Press the button on the
vehicle key in the vehicle interior to enable it to start the engine ⇒ Starting and stopping the
engine .
Locking the vehicle after airbags have been triggered
The entire vehicle is unlocked if the airbags are activated in an accident. Depending on the extent of
the damage, the vehicle can be locked as follows after an accident:
Switch the ignition off and then back on again.
Automatic deactivation of the sensors
The vehicle is not unlocked or locked for an extended period.
A sensor has been triggered an excessive number of times.
Reactivating the sensors:
Unlock the vehicle with the button in the vehicle key.

NOTICE

Please note that the sensors in the door handles can be activated by a powerful jet of water or
steam if a valid vehicle key is simultaneously within the operating range. If at least one window is
open and sensor surfaces on the door handles are continuously activated, all windows will close. All
windows could open if the jet of water or steam is moved away from the door handle sensors briefly
and then moved back again ⇒  .

It may not be possible to lock or unlock the vehicle using the Keyless Access if the 12-volt vehicle
battery or button cell in the vehicle key is weak or discharged. The vehicle can be locked or unlocked
manually ⇒  .

If there is no valid vehicle key in the vehicle or if it is not detected, a corresponding message will be
shown on the instrument cluster display. This may occur if the vehicle key is exposed to interference
from another radio signal or is covered by another item, e.g. an aluminium case ⇒ Starting and
stopping the engine .
Anti-theft alarm
Depending on the vehicle equipment level, the vehicle may have an anti-theft alarm.
The anti-theft alarm is activated automatically when the vehicle is locked using the vehicle key.
The anti-theft alarm outputs acoustic and visual warning signals for up to five minutes.
When does the system trigger an alarm?
If a door is opened.
If the bonnet is opened.
If the boot lid is opened.
If the ignition is switched on with a valid vehicle key. (The alarm may sound briefly.)
If the 12-volt vehicle battery is disconnected.
If there is movement inside the vehicle (in vehicles with interior monitoring) ⇒ Interior monitoring
system and anti-tow alarm .
If the vehicle is lifted or towed (vehicles with anti-tow alarm) ⇒ Interior monitoring system and anti-
tow alarm .
If the vehicle is transported on a car ferry or by rail (vehicles with anti-tow alarm or interior
monitoring) ⇒ Interior monitoring system and anti-tow alarm .
If a trailer that is connected to the anti-theft alarm system is removed ⇒ Trailer towing .
Switching off the alarm
Unlock the vehicle using the unlocking button on the vehicle key.

OR: switch on the ignition using a valid vehicle key. A short alarm lasting around one second may
sound.
On vehicles with Keyless Access: grip the door handle ⇒ Unlocking or locking the vehicle with
Keyless Access .

The anti-theft alarm will not function correctly if the 12-volt vehicle battery is weak or discharged.
Interior monitoring system and anti-tow alarm

Fig. 60 In the roof console: sensors for the interior monitoring system (arrows).
If movements are detected in the vehicle interior when the vehicle is locked, the interior monitoring
system will trigger an alarm ⇒ Fig. 60 .
The anti-tow alarm will be triggered if the vehicle is lifted.
Switching on the interior monitoring system and anti-tow alarm
Close the stowage compartments in the roof console so that the sensors can function.
Close the windows, glass roof, doors and boot lid
Press the locking button once.
The interior monitoring system and anti-tow alarm are activated.
Temporarily switching off the interior monitoring system and anti-tow alarm
The interior monitoring and the anti-tow alarm can be switched off temporarily in the Vehicle
settings menu in the Infotainment system ⇒ Infotainment system controls and displays .
To avoid false alarms, deactivate interior monitoring and the anti-tow alarm in the following
situations:
If any people or animals are to remain inside the vehicle.
If the vehicle is to be loaded onto another vehicle, transported or towed away.
If the vehicle is to be parked in a car wash or a two-storey garage.
If one or more windows or the glass roof are fully or partly open.

Automatic anti-dazzle interior mirror
When the ignition is switched on, the sensors measure the incident light from the rear ⇒ Fig. 86  ①
and from the front ②.
Depending on the values measured, the interior mirror dips automatically.
If the incident light on the sensors is hindered or interrupted, e.g. by a sun blind or other hanging
objects, the automatic anti-dazzle interior mirror will not function or will not function correctly.
Mobile navigation systems fitted to the windscreen or near the interior automatic anti-dazzle
interior mirror can also affect the sensors ⇒ .
The automatic anti-dazzle function will be deactivated in some situations, e.g. when reverse gear is
engaged.
Manual anti-dazzle interior mirror
Basic position: the lever on the lower part of the mirror is pointing towards the windscreen.
Pull the lever to the back to use the anti-dazzle function ⇒ Fig. 87 .

WARNING
The illuminated display from a mobile navigation device can lead to malfunctions of the interior
automatic anti-dazzle mirror and cause accidents or serious injuries.
You may not be able to precisely determine the distance from vehicles travelling behind you or from
other objects if the automatic anti-dazzle function malfunctions.
Exterior mirrors

First read and observe the introductoryinformation and safety warnings⇒Introduction 
Switch on the ignition.
Turn the rotary knob in the driver door to the desired symbol ⇒ Fig. 88 .

Vehicles with special body equipment or add-on parts
The manufacturers of body equipment and add-on parts must ensure that the body equipment and
add-on parts (conversions) adhere to the applicable environmental laws and regulations, particularly
the EU directive 2000/53/EC concerning end-of-life vehicles and EU directive 2003/11/EC concerning
the restrictions on the marketing and use of certain dangerous substances and preparations.
The vehicle owner should keep all assembly documentation for these conversions, and pass it on to
the disassembly company upon vehicle handover if the vehicle is scrapped. This is designed to
facilitate environmentally friendly disposal for all vehicles, including converted vehicles.
Windscreen repairs
To function properly, some items of equipment require an electrical or electronic module, which is
located on the inside of the windscreen near the interior mirror. If the windscreen has been
damaged in the viewing field of the electrical or electronic module, e.g. by stone impact, the
windscreen must be replaced. Repairing the crack can lead to malfunctions or faults in the
equipment.
After changing the windscreen, the camera and sensors must be set up and calibrated by a qualified
workshop.
Impairment or damage to sensors and cameras
Incorrectly performed repairs, structural changes to the vehicle, e.g. lowering the suspension,
retrofitted add-on parts or changes to the trim can lead to sensors and cameras being displaced or
damaged. This can also be caused by collisions, e.g. when parking, or also even by minor damage,
e.g. stone impacts on the windscreen.
Failure to observe this point may impair important functions (driver assist systems) and damage the
vehicle.
