Instrument Panel Gauge Cluster
WARNING
To prevent personal injury and / or death, or
damage to property, never operate the vehicle
when insufficient air pressure (less than 70 psi
[483 kPa]) is indicated for either the primary or
secondary air system. The volume of air required
to stop the vehicle may be greater than that
available. Have the brake system checked and
repaired before returning the vehicle to service.
There are 10 gauges in the instrument panel gauge cluster to
help monitor the vehicle while in service. Most gauges have
in-gauge warning indicators that 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.
Metric versions of the gauges and speedometer are available
as an option.
NOTE: 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.
