1) Make sure the following items.
• Place vehicle on a flat surface in front of blank wall (screen) (1) ahead of headlight surface.
Distance “a”
10 m (32.8 ft.)
• Adjust air pressure of all tires to the specified value respectively.
• Bounce vehicle body up and down by hand to stabilize suspension.
