different brands or types could damage vehi

Engine
NOTE: The engine in this vehicle may comply
with 2007 EPA emission standards. Consult the
engine manufacturer’s manual for changed lubri

cation and maintenance requirements.
Proper engine lubrication depends on the outside temper-
atures where you will be driving. Use the oil recom-
mended for the conditions you are most likely to be facing.
You will find a complete engine lubrication service guide in
the Engine Operation Manual that came with your vehicle.
There, the engine manufacturer explains more fully all the
maintenance operations that you and a qualified service
mechanic need to perform on your engine.
WARNING! Exhaust fumes from the engine
contain carbon monoxide, a colorless and
odorless gas. Do not breathe the engine
exhaust gas. A poorly maintained, damaged
or corroded exhaust system can allow carbon
monoxide to enter the cab or sleeper. Entry of
carbon monoxide into the cab is also possible
from other vehicles nearby. Failure to properly
maintain your vehicle could cause carbon
monoxide to enter the cab/sleeper and causes
serious illness
