■ Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision,
the system is design ed to automatically call the response center.
The responding agent receives th e vehicle’s location and attempts
to speak with the vehicle occupant s to assess the level of emer-
gency. If the occupants are unable to communicate, the agent
automatically treats the call as an emergency, contacts the nearest
emergency services provider to describe the situation, and
requests that assistance be sent to the location.

effective range, the door may lock and unlock repeatedly. Place the key
in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information
