PREPARATION BEFORE ADJUSTING

Before performing aiming adjustment, check the following:

• 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.

• Remove cargo and/or luggage to maintain an unloaded vehicle condition.

• Confirm spare tire, jack and tools are properly stowed.

• Carefully wipe off any dirt from headlamp lens.

CAUTION:

Do not use organic solvent (thinner, gasoline etc.)

• Place a driver or equivalent weight of 68.5 kg (150 lb) on the driver seat.

• By hand, bounce the front and rear of the vehicle to settle the suspension and eliminate any static load.

• Place the front tires in the straight ahead position.

• Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.

NOTE:

• For headlamp aiming details, refer to regulations in your area.

• By regulation, no means for horizontal aim adjustment is provided from the factory; only vertical aim is

adjustable.

• Use adjusting screw to perform aiming adjustment.

• Perform headlamp aiming if:

- The vehicle front body has been repaired.

- The front combination lamp has been removed or replaced.

- Any outfitting has been installed.

- The vehicle’s standard load condition has been substantially increased.

Aiming Adjustment Procedure

INFOID:0000000009175401

Aiming Chart

LOW BEAM AND HIGH BEAM

NOTE:

• Basic illuminating area for evaluation and/or adjustment should be within range shown on aiming chart. 
1. Use adjustment screw to perform aiming adjustment.

• Ensure fog lamps (if equipped) are turned off.

2. Block the opposite headlamp from projecting a beam pattern onto the adjustment screen, using a suitable

object. Aim each headlamp individually.

CAUTION:

Do not cover the lens surface with tape etc. The lens is made of resin.

3. Place the screen on the same level and flat surface as the vehicle.

NOTE:

• Surface should be free of any debris that would cause a difference between the headlamp center and

the adjustment screen.

4. Face the front of the vehicle to the screen and measure distance between the headlamp center and the

screen surface.
