• Do not park in an area of combustible
vapors or materials. You must keep
combustibles at least 5 ft. (1.5 m)
away from the exhaust (outlet)
stream (as it exits the tail pipe) while
the HEST lamp is illuminated. Always
park your vehicle outside. Failure to
do so could ignite an explosion or
harm bystanders which could result
in serious injury.
• Do not park in an area where people
are close by. You must keep
combustibles at least 5 ft. (1.5 m)
away from the exhaust outlet while
the HEST lamp is illuminated. Failure
to do so could result in serious injury.
• Do not approach the exhaust system
or surrounding areas without allowing

serious burns to the skin.

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,
