Warning Lights and Indicators
Page 17
Report the fault to
service/maintenance
personnel.
18. Motor Over-Speed Warning
Indicator
This red indicator illuminates
when the vehicle’s speed
exceeds the maximum limits of
the hybrid propulsion system.
Speed must be reduced by
activating the vehicle brakes,
failure to do so may result in
damage to the hybrid
propulsion system.
19. Low Steering Fluid Indicator
This red indicator illuminates
when the fluid level in the
steering pump reservoir is low.
Report the fault to
service/maintenance personnel
immediately.
20. Stop Hybrid Electric Vehicle
(HEV) Indicator
This red indicator illuminates
and an audible alarm is
activated when a severe fault is
detected within the hybrid
propulsion system.
Immediately move the vehicle
to a safe location and shutdown
engine.
See “Stop HEV
Indicator” on page 44.
21. Class Door Error Indicator
This red indicator illuminates
when a fault has been detected
with the rear door Contact-less
Acoustic Sensing System.
The class error fault will not
prohibit operation of the rear
doors.
22. Regenerative Braking
Applied Indicator
This red indicator illuminates
when regenerative braking is
occurring in the hybrid
propulsion system.
23. Regenerative Braking OFF
Indicator
This red indicator illuminates
when regenerative braking
switch, located in the front
destination sign compartment,
is placed in the OFF position.
24. High Exhaust System
Temperature (HEST)
Indicator
This amber indicator illuminates
to notify the operator of a high
heat hazard caused by the
exhaust system entering the
process of active regeneration.
When the vehicle is engaged in
active regeneration, the
exhaust will produce
temperatures in excess of
812°F (433.3°C) and caution
must be taken to ensure a two
foot minimum clearance of the
Exhaust heat can reach 812°F
(433.3° C). Ensure that the
exhaust outlet is away from
areas that could potentially be
damaged by severe heat.
