6-8 Starting and Stopping Procedures
PA-1628Operator's ManualH3-45 COACH
l Low engine oil pressure
l High crankcase pressure
After the automatic engine shutdown sequence, the
engine may be restarted. To do so, turn the ignition
switch to the OFF position for 7 seconds and then
turn it back to ON. However, it will only operate for
30 seconds unless the problem is resolved.
Use this function sparingly and in order to move the
vehicle to a safe parking place only. Excessive use
may result in severe engine damage.
WARNING
Failure to take necessary action when the STOP
telltale light is on can ultimately result in automatic
engine derate and shutdown.
IDLE SHUTDOWN TIMER
The idle shutdown timer (optional) is programmed to
shut down the engine after a specific engine idling
time. The idling time cannot be changed by the driver
but can be changed with the use of a laptop
computer and Premium Tech Tool. In this case, the
engine idling time can be set from 30 seconds up to 1
hour.
The engine will shut down at the set time under the
following conditions:
l Vehicle speed is 0;
l Engine is running at normal idle speed;
l Engine coolant temperature above 120°F
(49°C);
l Temperature inside vehicle is between 59°F
(15°C) and 81°F (27°C);
l Parking brake applied;
l Transmission into neutral (N);
l Wheelchair lift system not in use;
Pressing the fuel pedal will prevent engine shutdown
and restart countdown.
ENGINE BLOCK HEATER
The vehicle may be equipped with an engine
immersion-type electric block heater to assist cold
weather starting. A connector is on the rear pillar of
the curbside engine compartment door frame. Using
an extension cord, connect to a 110 - 120 VAC
outlet.
CAUTION
Connect only to a 120 VAC power source. Use
only grounded (three prongs) extension cords with
a minimum rated capacity of 15 A. Disconnect the
extension cord before starting. Before driving,
make sure the extension cord is disconnected.

ENGINE WARM-UP
After starting the engine, keep the parking brake
applied and let the engine run at normal idle for two
minutes to allow lubricating oil to reach the
turbocharger. Increase engine speed to fast idle,
using the fast idle switch located on the dashboard
for five minutes, without loading the engine. Monitor
the gauges and indicator lights to make sure all
conditions are normal. If an abnormal condition is
observed, stop the engine immediately and have the
condition corrected.
NOTE
The engine will reach normal operating temperature
shortly after driving. Avoid driving at full throttle
until engine coolant temperature reaches 140°F
(60°C).
