4RUNNER (1998) TURN SIGNALS To signal a turn, push the headlight/turn signal lever up or down to position 1. The key must be in the "ON" position. The lever automatically returns after you make a turn, but you may have to return it by hand after you change lanes. To signal a lane change, move the lever up or down to the pressure point (position 2) and hold it. If the turn signal indicator lights (green lights) on the instrument panel flash faster than normal, a front or rear turn signal bulb is burned out. Emergency flashers
