Lamp Combination
After prolonged idle, you may notice momentary white vapor
and odor. This is normal.
Use only Ultra Low Sulfur Diesel (ULSD) fuel.
Oil classification CJ-4 (low ash) is the recommended oil.
This will increase the time between regeneration events.
Exhaust-Related Engine Indicator
Lamps
Malfunction Indicator Lamp
The MIL illuminates when the On-Board Diagnostics system
detects a malfunction related to the emissions control system.
The illuminated MIL indicates that the engine and
aftertreatment system should be diagnosed and serviced at
your next available opportunity.
Diesel Exhaust Fluid (DEF) Lamp
Illuminated
An illuminated DEF lamp is an indication that the DEF level is
low. This can be corrected by refilling the DEF tank.
Flashing
A flashing DEF lamp indicates that the DEF level has fallen
below a critical level. This can be corrected by refilling the DEF
tank.
Flashing with Warning or Check Engine
Lamp
A flashing DEF lamp combined with an illuminated Warning or
Check Engine lamp indicates that the DEF level is critically low
and you will experience a power loss. Normal engine power
will be restored after refilling the DEF tank.
Stop Engine Lamp with Flashing DEF and
Warning or Check Engine Lamp
If the engine has been shut down or has idled for one hour
after the DEF tank has been run dry, the Stop Engine Lamp will
also be illuminated along with the flashing DEF lamp and
illuminated Warning or Check Engine lamp. Engine power will
continue to be reduced automatically. The vehicle will also be
limited to 5 M.P.H. (8 K.P.H.). Normal engine power and
vehicle speed will be restored after refilling the DEF tank.
