If vehicle front body has been repaired and /or the headlamp assembly has been replaced, check headlamp
aiming.
●
Before performing aiming adjustment, check the following:
–
Confirm headlamp aiming switch is set to "0" (zero) position.
–
Ensure all tires are inflated to correct pressure.
–
Place vehicle and screen on level surface.
–
Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.
–
Confirm spare tire, jack and tools are properly stowed.
–
Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
–
Use adjusting screw to perform aiming adjustment
