Steering Effort Inspection Procedure
1 Place a vehicle on the paved flat ground with front wheels in a straight ahead position.
2 Start the engine and run it at 1,000rpm.
3 Using a scale, measure the steering effort in both directions.
NoticeThe difference in steering effort of left and right should be within 0.6 kg.

9B-10 LIGHTING SYSTEM Head Lamp Focusing When using the beam setting device
1. The head lamp focus should be adjusted by using a properbeam setting device.
2. Adjust the head lamp focus by using Up/Down, Left/Right adjusting screws.
When using the screen
1. Put the vehicle on the leveling surface.
2. One person is needed to seat on the driver's seat without other loads(CVW) and check the tire pressure if it is in the specification.
3. The distance between the headlamp and the screen is 25m.
4. Draw the vertical line (crossing the center of each headlamp) on the screen.
5. Start the engine.
6. Check if the cut-off line of the headlamp on the screen is in the specification.
1 ) Left/right direction
- The degree of the cross point at the cut-off line of theheadlamp and the vertical line should be 15.
2 ) Up/down direction - The distance between the cut-off line of the headlampand the horizontal line should be 25cm.
7. Adjust the focus if the cut-off line of the headlamp is out of
the specification by using up/down, left/right adjusting screws. A : Up/down direction adjusting screwB : Left/right direction adjusting secrw
