Section 3.2: Brake Override
Section 3.3: Brake Start
When the chassis engine is started, the base idle RPM
is reached, and lead-acid charge set point is reached,
the five-second countdown will appear. During the five-
second countdown, the engine shutdown sequence can
be overridden by pressing and holding the vehicle’s brake
pedal, thus engaging Brake Override (if applicable). When
in brake override the engine running icon will have a yellow
flashing background.
•
The engine will remain at idle as long as the override is
active.
•
To disengage Brake Override and initiate the engine
shutdown sequence again, perform one of the following
actions (depending on your system settings):
1. Release the brake pedal.
2. Press and hold F1.
When the chassis engine is off and the IMS is active, the
chassis engine can be started quickly by pressing the brake
pedal.
