Automatic Update of Charge Facility/Search for Nearest Charge Station

Automatic update of charge facility

• Nearby charge stations around the user's vehicle (area of within a radius of 25 km <15-1/2 miles> from the

vehicle) are automatically updated when the low battery warning lamp turns ON.

• Neighborhood charge stations around user's house (area within approximately 160 km <approx. 100 miles>)

are automatically updated periodically.

Search for nearest charge station

• If the battery capacity is low during driving, a charge warning is given in 3 steps. If the user follows the warn-

ing, data is sent/received to/from the Nissan CARWINGS Data Center. Charge facilities around the vehicle

are searched, and guidance is started on the navigation system. The search location is memorized on the

AV control unit as charge station information.

• When the user selects update of the charge facilities in the area, data is sent and received to/from the Nis-

san CARWINGS Data Center. Charge facilities around the area are searched, and the locations searched

are memorized to the AV control unit as charge station information.

NOTE:

Up to approximately 1,000 charge stations can be memorized.

Information channel/probe information

• Start the navigation menu or power switch with external signals and perform data communication with the

Nissan CARWINGS Data Center through TCU.

• Information channel obtains various kinds of information such as Internet content prepared by the Nissan

CARWINGS Data Center and provides voice guidance and display guidance.

• For voice sound used in the information channel, TCU receives the text data from the Nissan CARWINGS

Data Center through the TEL antenna in packet communication and sends it to the AV control unit. The AV

control unit converts the text data to voice signal and sends it to the front speaker.

• If CARWINGS reading voice is output while the audio is ON and/or the voice guidance is being output, these

audio sounds are muted and only the CARWINGS reading voice is output.

• Various vehicle information data (battery condition, driving distance, warning display, etc.) is sent to the Nis-

san CARWINGS Data Center to store the data. The timing for transmission is the information channel, ECO

drive connection, fastest route search and connection to operator service.
