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.
Remote Air Conditioning (Immediate ON/Timer Reservation) Operation
Before/after driving the vehicle, remote air conditioning operation can be performed through the Nissan CAR-
WINGS Data Center by operating a user's cellular phone or PC. When using the remote control operation, the
vehicle must be stopped in a location where radio waves between the Nissan CARWINGS Data Center and
the vehicle can be received.
Immediate ON operation
• Vehicle air conditioning can be turned ON by remote control by operating a user's cellular phone or PC.
NOTE:
If air conditioning is operated with the charging plug inserted, battery power is saved.
OPERATION PRINCIPLE
- The user operates the remote air conditioning with a cellular phone or PC and sends the data to the Nissan
CARWINGS Data Center via the web site.
