Indicator lights in instrument cluster,
locations (1998 through 1999)


Note:
With the exception of two indicator lights, all the
remaining indicator lights are equipped with Light
Emitting Diodes (LEDs). This means that if one
LED fails, the instrument cluster must be
replaced.

If the instrument cluster is replaced in vehicles with outside temperature
display or if outside temperature display is added later, cover -C- must be
removed from the Lowline model. 1 - High beam indicator lamp - 1.2 W/1.1 W (Nippon Seiki)/ (VDO)
