Readings Screen
The 3D Readings screen displays the primary
vehicle alignment information in an intuitive,
three dimensional format. The screen
appears as a vehicle with the body lifted off,
viewed from the rear and above. Review
the figure shown to become familiar with the
screen layout and functions.
Each wheel angle has a numeric reading as
well as a graphical meter display indicating
directional orientation and relationship to
specifications. Camber meters, located along
the top of each tire, have a line that indicates
camber relative to the preferred specification.
Toe meters, projected onto the ground in front
of each tire, have an arrow that indicates the
toe angle. Caster is represented by a meter
in front of each wheel after a caster swing is
performed. The numeric value for caster is
directly above the meter. When a meter is
green, the reading is within specifications.
When the arrow is centered within the green it
is at the preferred value. A red meter indicates
the reading is out of specification. The red
meter contains a green band, indicating the
direction of needed change. A gray meter
indicates there is no specification for that
angle.
All numeric readings on this screen are actual
live measurements, including caster. If any
angles require correction, make sure the
brake pedal depressor is engaged and the
steering wheel is centered and locked, then
simply begin the adjustment. As the angles
change the display will update to reflect the
new readings. The numeric values change
and the meter indicators move in the direction
of change. Click on OK to proceed to the next
readings screen.
