Fig. 1.103. Headlight corrector switch
To adjust the direction of the headlight beam depending on the number of passengers and the weight of the cargo carried by the vehicle, turn the headlight corrector switch.
The higher the headlight range control switch position number, the lower the beam of light from the headlights will be directed. Always use the headlight range control switch to adjust the distance illuminated by the headlights (when the low beam is on) so as not to blind oncoming drivers.
The following are examples of correct headlight beam adjustment. Under vehicle loading conditions other than those listed below, set the switch to the position that most closely matches the descriptions in the table.
