The remote control key is not physically used when starting since the car is equipped with support for keyless starting (Passive Start) as standard. The key must be in the front part of the passenger compartment, e.g. in the driver's pocket or the runnel console cup holder, for it to be possible to start the car.
Keyless locking and unlocking of doors, tailgate (Passive Entry*) is also available as an option. The key then has a range extending in a semicircle with a radius of approx. 1.5 metres (5 feet) out from the driver's door and approx. 1 metre (3 feet) out from the tailgate respectively.
With keyless starting and keyless locking and unlocking, the remote control key can be located anywhere in the passenger compartment or the cargo area and maintain the functionality to start the car.
Each one of the remote control keys included with the car can be linked to a driver profile with unique settings for the car. When a key with a certain profile is used, the car's settings are adapted according to the profile.
Button-less key (Key Tag)
For cars equipped with keyless locking and unlocking*, a slightly smaller, lighter and button-less key (Key Tag) is supplied. It works the same way as the normal remote control key when it comes to keyless starting and locking and unlocking1. It has no detachable key blade and the battery cannot be replaced.
Remote control key buttons
Locking - Pressing the button locks the doors, tailgate and fuel filler flap and also arms the alarm*. - Press and hold to close all of the windows and the panorama roof* simultaneously.
Unlocking - Pressing the button unlocks the doors and tailgate and also disarms the alarm.- A longer press opens all windows simultaneously2.
Tailgate - Unlocks the tailgate only and disarms its alarm. On cars with power operated tailgate*, the tailgate is opened automatically when the button is held depressed. The tailgate is also closed with a long press - acoustic warning signals sound. 
Panic function – Used to attract attention in an emergency. Press and hold the button for at least 3 seconds or press it twice within 3 seconds to activate the direction indicators and the horn. The function can be turned off with the same button once it has been active for at least 5 seconds. Otherwise the function switches off automatically after 3 minutes.
Warning
If anyone is left in the car, make sure the power windows and panoramic roof* are de-energised by always taking the remote control key with you when you leave the car.
Note
Be aware of the risk of locking the remote control key/Key Tag in the car.
A remote control key/Key Tag left in the car will be deactivated when the car is locked and the alarm is armed using another valid key. The "Double lock" function is also deactivated.
The deactivated key is reactivated when the car is unlocked.
Interference
Remote control key functions for keyless starting and keyless locking and unlocking* can be disrupted by electromagnetic fields and screening.
Note
If there is still interference - use the remote control key's detachable key blade to unlock and then place the key in the backup reader in the cup holder to disarm the car.
