  3. PRECAUTIONS FOR INSPECTING POWER SOURCE FOR MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) (w/ Door Control Battery)

    The vehicle battery supplies power to the main body ECU (multiplex network body ECU) via the door control battery. If a main body ECU (multiplex network body ECU) power source malfunction occurs, the door control battery may be malfunctioning.

  4. PRECAUTION FOR BULB REPLACEMENT


    1. Always prepare a new bulb for immediate replacement. While replacing the bulb, the lens may attract dust and moisture if the bulb is removed from the vehicle for a long time.

    2. Always replace a bulb with another bulb of the same wattage.

    3. If only replacing the bulb on one side, differences in brightness and lighting color between the right and left sides may occur.

    4. Securely install the socket after bulb replacement. The lens may become cloudy or the light assembly may fill with water through gaps around the socket if it is not installed securely.

  6. PRECAUTION FOR AUTOMATIC HIGH BEAM SYSTEM (w/ Automatic High Beam System)


    1. General Description

      The automatic high beam system is a system that helps ensure visibility by automatically turning the high beam headlights on and off. Additionally, due to control limitations of the automatic high beam system, it may be necessary to manually turn the high beam headlights on and off. For safety reasons, make sure to turn the high beam headlights on and off manually according to the driving conditions.

    2. Conditions Unsuitable for Using Automatic High Beam System

      Under the following conditions, the automatic high beam system might not detect other vehicles or lights correctly, or the high beam headlights might cause glare or flash pedestrians or the occupants of other vehicles. Manual operation should be considered.

      Factor Condition
      Weather/Climate When driving in bad weather (rain, snow, fog, sandstorms, etc.).
      Front windshield
      • When the windshield glass is not clear (ice, snow or frost on the glass).

      • When the windshield glass is dirty (sand, mud, water stains or bugs on the glass).

      • When the windshield glass is cracked.

      • When the windshield glass is fogged-up.

      • When the windshield glass has a film attached.

      • When an object on the instrument panel reflects off of the windshield glass.

      • When any other abnormal conditions exist with the windshield glass.

      Forward recognition camera
      • When the forward recognition camera is deformed.

      • When the forward recognition camera is dirty.

      • When any other abnormal conditions exist with the forward recognition camera.

      Nearby vehicles or lights
      • When lights similar to headlights or taillights are in the vicinity of the vehicle.

      • When a nearby vehicle has no lights or its lights are off.

      • When a vehicle in front has misaligned lights, or its lights are changing color.

      • When a vehicle in front has extremely dirty headlights or taillights.

      Road conditions
      • When driving in areas where the conditions often change between bright and dark.

      • When driving on hilly roads.

      • When driving on winding roads or around sharp curves.

      • When driving on bumpy roads (cobblestone paving, gravel roads, rough unpaved roads, etc.).

      • When highly reflective objects are in front of the vehicle (mirrors, road signs, etc.).

      Own vehicle
      • When the headlights are damaged, deformed or dirty.

      • When the vehicle posture is abnormal (posture has changed due to the vehicle being fully loaded, a trailer being towed, road conditions, etc.).

      • When the vehicle has other malfunctions or has been modified.

      Automatic high beam system

      Malfunction:

      When the automatic high beam indicator light on the combination meter assembly is off and "Headlight System Malfunction Visit Your Dealer" is displayed on the multi-information display.

      Others:


      • When the automatic high beam system does not seem to be turning the high beam headlights on and off properly.

      • When the automatic high beam system is frequently turning the high beam headlights on and off.
