NOTE
The length of time the 'Wait-To-Start'
lamp
remains illuminated depends on
the ambient temperature. The lower
the ambient temperature, the longer
the lamp will be illuminated.
Once the Wait-to-Start light turns off, turn
the key to the starting position to start the
engine.
Y
ou may see this appear if the system has
detected a situation where the starter is too
hot and needs to cool down. Alternatively,
you may see it when the engine grid heater
is on and needs some time to warm up.
NOTE
Some engines are equipped with an
engine
starting motor protection fea-
ture. If the starting motor is engaged
for 30 or more seconds, without the
engine starting, the starter will be
locked out from operating, allowing for
proper cooling of the starting motor.
During this time, the 'Wait-To-Start'
lamp will flash for 2 minutes. Once the
lamp stops flashing, the starting motor
will be allowed to function.
