Service
Location:
Physical Telltale (Position 8 on Cluster)
Color: Amber (Yellow)
Purpose:
This telltale illuminates when the truck
needs to be serviced or permanent
damage could occur.
Stop Powertrain
Location:
Digital Telltale (Position 2 on Cluster)
Color: Red
Purpose:
This telltale illuminates when the truck
needs to be pulled over. Failure to stop
the truck could result in injury, death, or
permanent damage to the truck.
Limited Performance Mode
Location:
Physical Telltale (Position 8 on Cluster)
Color: Amber (Yellow)
Purpose:
This telltale illuminates when the truck
will be severely derated (i.e. below 25%
power output allowed).
Regenerative Braking System
Location:
Physical Telltale (Position 8 on Cluster)
Color: Amber (Yellow)
Purpose:
RBS stands for “Regenerative Braking
System.” This telltale illuminates when
the regenerative braking system is
severely derated or disabled due to
abnormal operating conditions such as
extreme ambient temperatures or long
downhill grades.
If the RBS telltale is activated, or the
high voltage battery pack is at a high
state of charge, the operator must rely
on the foundation brakes. If neither the
Service Telltale or the Stop Telltale are
activated, the truck may be driven while
the RBS telltale is activated.
WARNING!
Above 95% state of charge,
regenerative braking is severely
derated or disabled, and the RBS
telltale will NOT activate. If either the
RBS telltale is activated, or the high
voltage battery pack is above 95%
state of charge, the operator must use
the brake pedal to slow the vehicle.
Failure to comply may result in injury,
death, or property damage.
