on the DEF gauge and additional warning
lamps in the instrument cluster.
DEF Warning Lamp in Instrument Cluster
Diesel Exhaust Fluid (DEF) Gauge
2 1
1. DEF Symbol
2. DEF gauge warning lamp
The DEF lamp(s) will illuminate when the
fluid in the DEF tank reaches a low level. If
the lamp illuminates but the level is full,
seek service immediately for DEF fluid
quality or DEF equipment repair.
Engine Wait-To-Start Lamp
This warning icon will appear when the
system needs some time before attempting
to start the engine. The lamp 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 lamp 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.
(PACCAR PX and Cummins ISL engines)
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.
Engine Braking System
An engine compression brake is standard
on the PX-7 engines. Optionally, this
engine may be equipped with an exhaust
brake. When activated, these devices
create a braking effect on the drive wheels.
Because it can help keep your vehicle’s
brakes from overheating, it can save wear
and tear on the service brakes. However,
the engine compression or exhaust brake
is not an emergency brake or the primary
vehicle brake.
