The remote key is not physically used to start the ignition because the vehicle is standard-equipped with keyless start (Passive Start). To start the vehicle, the key must be in the front section of the passenger compartment, e.g. in the driver's pocket or in a cup holder in the tunnel console.
The keyless system for locking/unlocking the doors, tailgate (Passive Entry*) and fuel filler door is available as an option. This system has a range in a semicircle with a radius of approximately 1.5 meter (5 feet) out from the driver's door and approx. 1 meter (3 feet) out from the tailgate.
With keyless start in combination with keyless locking and unlocking, the remote key can be located anywhere in the passenger compartment or cargo compartment in order to start the engine.
Each remote key supplied with the vehicle can be linked to a driver profile with unique settings for the vehicle. When a key with a specific profile is used, the vehicle settings are adjusted according to that profile.
Buttonless key, Key Tag
For vehicles equipped with keyless locking and unlocking*, a smaller, lighter and button-less key (Key Tag1) is also provided. It works the same way as the regular remote key as regard keyless start and keyless locking and unlocking2. It does not have a detachable key blade and its battery cannot be replaced.
