After the above conditions have finished and the necessary operating conditions are satisfied, the I-LI system application of the brakes will resume.

• "Not Available Poor Road Conditions":
  When the VDC system (except Traction Control System [TCS] function) or ABS operates.

Action to take:

When the above conditions no longer exist, turn off the I-LI system. Push the ProPILOT Assist switch (for vehicles with ProPILOT Assist) on the steering wheel again to turn the I-LI system back on.

Temporary disabled status at high temperature:

If the vehicle is parked in direct sunlight under high temperature conditions (over approximately 104ºF [40ºC] ) and then the I-LI system is turned on, the I-LI system may be deactivated automatically, a chime will sound and the following message will appear in the vehicle information display: "Unavailable: High Cabin Temperature."

System malfunction

If the I-LI system malfunctions, it will cancel automatically. The LDW indicator (orange), along with a message will appear in the vehicle information display, and a chime will sound. If the LDW indicator (orange) illuminates in the display, pull off the road to a safe location and stop the vehicle. Turn the engine/motor off and restart the engine/ motor. If the LDW indicator (orange) continues to illuminate, have the I-LI system checked. It is recommended that you visit a NISSAN dealer for this service.

System maintenance

The lane camera unit 1 for the I-LI system is located above the inside mirror. To keep the proper operation of the I-LI system and prevent a system malfunction, be sure to observe the following:

• Always keep the windshield clean.
• Do not attach a sticker (including transparent material) or install an accessory near the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument panel. The reflection of sunlight may adversely affect the camera unit’s capability of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the camera lens or remove the screw located on the camera unit. If the camera unit is damaged due to an accident, it is recommended that you visit a NISSAN dealer.
