Remote key
The remote key is used to lock and unlock doors, the tailgate and the fuel filler door. The remote key must be in the vehicle in order to start the engine.
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 vehicle. For vehicles with Passive Entry, a smaller, lighter and buttonless key (Key Tag) can be purchased as an accessory.
The remote keys2 can be linked to different driver profiles to store personal settings in the vehicle.
Warning
The remote key contains a button cell battery. Keep new and used batteries out of the reach of children. If batteries are swallowed, they can cause serious injury.
If any damage is detected, e.g. if the battery cover cannot be closed properly, do not use the product. Keep defective products out of the reach of children.

Note
Be aware of the risk of locking the remote key in the vehicle.
If the remote key or key tag is left in the vehicle, it will be deactivated when the vehicle is locked and the alarm set using another valid key. The key will be reactivated when the vehicle is unlocked.
Button-less key (Key Tag)*
A buttonless key3 can be ordered as an accessory for vehicles equipped with the keyless locking and unlocking function. A buttonless key works the same way as the regular remote key as regards keyless start and keyless locking and unlocking. The key is waterproof up to a depth of approx. 10 meters (30 feet) for up to 60 minutes. It does not have a detachable key blade and its battery cannot be replaced.
Care Key - restricted remote key
A Care Key enables the vehicle owner to set a maximum speed limit for the vehicle. This limit is intended to promote safe use of the vehicle, e.g. when it is loaned out.
Interference
Electromagnetic fields or obstructing objects may interfere with the remote key's functions for keyless start and keyless locking and unlocking*.
Note
If you experience interference, use the remote key's detachable blade to unlock the vehicle and then place the remote key in the backup reader in the tunnel console storage compartment to disarm the alarm and start the vehicle.
