PANEL DIMMER CONTROL
Use to adjust the brightness of the
instrument panel and all applicable
illuminated switches in the vehicle
during headlamp and parklamp
operation.
Move the control to the full upright
position, past detent, to turn on the
interior lamps.
Note: If the battery is disconnected,
discharged, or a new battery is
installed, the dimmer switch requires re-calibration. Rotate the dimmer
switch from the full dim position to the full dome/on position to reset.
This will ensure that your displays are visible under all lighting
conditions
The dome lamp will not illuminate if the control switch is not rotated
past the detent.
VERTICAL AND HORIZONTAL AIM ADJUSTMENT (SEALED BEAM
HEADLAMPS)
The headlamps on your vehicle are intended to be aimed using
mechanical aimers. If mechanical aimers are used and the cross-car sight
line is in any way blocked, set the legs of the universal adaptor all to the
same setting, such that the cross-car sight line is no longer blocked, per
the instructions for the brand of mechanical aimer used. You can also
aim the headlamps visually using the procedure below.
