Gauges
There are six standard and four optional gauges in the
instrument panel gauge cluster to help monitor the vehicle
while in service. Most gauges have in-gauge warning
indicators which turn ON if the gauge pointer moves into
an out-of-acceptable-range condition. When the ignition switch
is turned ON, the gauge indicators will be ON. If any indicator
fails to go out after starting engine, stop engine and determine
cause of the gauge indication that is out of acceptable range.
Metric versions of the gauges and speedometer are available
as an option.
