Illuminates when the engine retarder
(compression brake or exhaust brake)
switch is turned on.
Engine, Stop Engine
Illuminates and an audible alarm tone will
sound when a major engine system
problem exists.
WARNING
If the Stop Engine warning light illumi-
nates, it means you have a serious en-
gine system problem. This should be
considered an emergency. You should
stop the vehicle as safely as possible
and turn OFF the ignition. The vehicle
must be serviced and the problem cor-
rected before driving again. Failure to
comply may result in death, personal
injury, equipment or property damage.
Engine Wait-to-Start Light
This warning icon will appear when the
system needs some time before attempting
to start the engine. The light will illuminate
at key ON, and will stay on for a period of
up to 30 seconds.
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.
You 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.
Emissions, Engine Derate
Fifth Wheel Slide Unlocked
Illuminates when fifth wheel slide switch is
activated. Indicates fifth wheel can move.
