KEY, LOCKS AND ALARM
Remote key
The remote key is used to lock and unlock
doors, the trunk lid and the fuel filler door.
The remote key must be in the vehicle in
order to start the engine.
Remote key 3 and button-less key (Key Tag)*.
The remote key is not physically used to start
the ignition because the vehicle is standard-
equipped with keyless start (Passive Start).
The key only needs to be in the front section of
the passenger compartment.
For vehicles equipped with keyless locking
and unlocking (Passive Entry)*, the engine can
be started with the key anywhere in the vehi-
cle. A smaller, lighter and button-less key (Key
Tag) is also provided.
