• The KEYLESS-GO key can be used like a conventional key.
• You can combine KEYLESS-GO functions with those of a conventional key, e.g. unlock with KEYLESS-GO and lock with the button.
• Always carry your KEYLESS-GO key on your person.
• Do not keep the KEYLESS-GO key together with:
- electronic devices, e.g. a mobile phone or another key
- metallic objects, e.g. coins or metal foil.
This can affect the functionality of KEYLESS-GO.
• When locking and unlocking using KEYLESS-GO, the distance between the SmartKey and the corresponding door handle must not exceed 3 ft (1 m).
• If the vehicle is parked for more than 72 hours, the KEYLESS-GO function is deactivated. Pull the outer door handle and switch on the ignition to reactivate the KEYLESS-GO function.
• If the KEYLESS-GO key is removed from the vehicle, it is possible that the system may not recognize the SmartKey. The vehicle can then not be locked or started using KEYLESS-GO.
• If the KEYLESS-GO key has been removed from the vehicle, e.g. if a passenger leaves the vehicle with a KEYLESS-GO key:
- if the start/stop button is pressed or if an attempt is made to lock the vehicle with the locking button on the outer door handle, the Key Not Detected message appears in the multifunction display
- when the engine is running, the red Key Not Detected message appears in the multifunction display as you pull away.
Find the KEYLESS-GO key and change its position in the vehicle. Carry the KEYLESS-GO key in your shirt pocket, for example.
• If you have started the engine with the Start/Stop button, you can switch it off again by:
- pressing the Start/Stop button again
- inserting the KEYLESS-GO key into the ignition lock if the vehicle is stationary and the automatic transmission is in park position P.
• You could unlock the vehicle by mistake if the distance between the KEYLESS-GO key and the vehicle is less than 3 ft (1 m) and:
- an exterior door handle is hit by a water jet
or
- you clean an exterior door handle.
• Bear in mind that the engine can be started by any of the vehicle occupants if there is a KEYLESS-GO key in the vehicle.

To unlock the vehicle: pull the door handle.
To lock the vehicle: touch sensor surface 1.
Convenience closing feature: touch recessed sensor surface 2 for an extended period.

If you pull on the handle of the trunk lid, only the trunk of the vehicle is unlocked.
