      *a Automatic High Beam Indicator Light

      Check the operation of the automatic high beam indicator light.

      Note

      If the inner rear view mirror assembly cannot correctly recognize the front due to bad weather (dense fog, etc.) or obstructions, the automatic high beam indicator in the combination meter assembly may not illuminate, and the automatic high beam system may not operate.


      1. Turn the engine switch on (IG).

      2. Turn the headlight dimmer switch to the AUTO position and check that the low beam headlights are on.

      3. Turn the dimmer switch to the high position.

        Tech Tips

        If the automatic high beam switch is turned on when the light control switch is not in the AUTO or head position, or the dimmer switch is not in the high position, the message shown in the illustration will be displayed on the multi-information display.

      5. The shift lever is in any position other than R.

      6. Check that the automatic high beam indicator comes on.

    2. Check the operation of the automatic high beam function.


      1. At night, when driving the vehicle with the automatic high beam system in standby mode, check that the high beams automatically turn on after a short delay when all of the following conditions are met:


        • Vehicle speed is more than 30 km/h (19 mph).

        • The area in front of the vehicle is dark.

        • There are no oncoming vehicles with headlights on.

        • There are no preceding vehicles with taillights on.

        • There are few streetlights along the street ahead.

        Note

        The low beams may not change to high beams due to illumination from city lighting, signals or billboards, or due to reflective surfaces, such as signs or signboards.

      2. At night, when driving the vehicle with the high beams turned on by the automatic high beam system, check that the automatic high beam system turns off the high beams and returns to standby mode when any of the following conditions are met:


        • Vehicle speed is less than 25 km/h (16 mph).

        • The level of ambient light is higher than a specified threshold.

        • There are oncoming vehicles with headlights on.

        • There are preceding vehicles with taillights on.

        • Light from streetlights ahead is higher than a specified threshold.

        Note


        • Under the following conditions, the high beams may change to beams.


          1. There is interference from other illumination, such as city lighting, signals or billboards, or reflective surfaces, such as signs or signboards

          2. There is interference from the fog lights of an oncoming vehicle


        • Under the following conditions, the high beams may not change to beams.


          1. Passing an oncoming vehicle on a curve

          2. Preceding or oncoming vehicle appears and disappears on a continuous curve

          3. Preceding or oncoming vehicle appears and disappears due to the median, roadside trees or other obstructions

          4. Another vehicle cuts in front of the vehicle

      3. When any of the following conditions are met, the automatic high beam system will be canceled and the indicator light will turn off:


        • The engine switch is turned off.

        • The light control switch is turned to any position except the AUTO or head position.

        • The dimmer switch is moved to the low position.

        • The automatic high beam switch is turned off.


    1. General Description

      The automatic high beam system is a system that helps ensure visibility by automatically turning the high beams on and off. In addition, due to control limitations of the automatic high beam system, it may be necessary to manually turn the high beams on and off. For safety reasons, make sure to turn the high beams 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 beams might cause glare or flash pedestrians or the occupants of other vehicles. Manual operation should be considered.

      • When any other abnormal conditions exist with the inner rear view mirror assembly.
      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.
