DIESEL ENGINE FEATURES
DIESEL EXHAUST FLUID (DEF)
DEF reduces the amount of regulated emis-
sions produced by the diesel engine. The
DEF level must be maintained for the vehicle
to run properly. As the DEF level becomes
low, warnings are displayed on the Driver
Information Center. These warnings will
increase in intensity as the DEF level is
reduced. As the tank nears empty, vehicle
speed will be limited in a series of steps.
At least 2 gallons of DEF must be added to
release the speed limitation.
The DEF fill port (blue cap) is located on the
rear of the passenger-side fender, behind
the front wheel.
DIESEL PARTICULATE FILTER (DPF)
The DPF filters the diesel exhaust gas to
reduce emissions. Occasionally, the DPF
needs to be cleaned. When needed, the
DPF will clean itself as part of normal
operation as the vehicle is driven. If driving conditions do not allow the cleaning to take
place, a Driver Information Center message will be displayed.
