Fuel Economy
Diesel engines offer superb fuel economy under
certain conditions. Fuel economy should im-
prove after the vehicle is broke in. Many factors
will affect or reduce fuel economy.
• After-treatment Regeneration
• Cold Temperatures
• Wind
• Extended Idling
• Towing
• Short Trips
• Fuel Quality
• City Driving
• Aftermarket Grills
• Oversized Tires
• Gear Ratios
If at any time your check engine light is on,
please visit an authorized dealer.

Diesel Exhaust Fluid
Your truck is equipped with a Selective Cata-
lytic Reduction (SCR) exhaust emissions after-
treatment system. This technology is used to
reduce Nitrogen Oxides (NOx) emissions of the
engine so that it meets current U.S. EPA and
California exhaust emissions requirements.
This system is new to many truck operators and
does require some maintenance for proper op-
eration.
In order to function properly and ensure the
vehicle meets applicable emissions standards,
the SCR system injects Diesel Exhaust Fluid
(DEF) into the exhaust upstream of the SCR
catalyst. The DEF reacts with the exhaust gas
inside the catalyst to convert NOx to harmless
gasses prior to release into the atmosphere.
DEF consumption varies with vehicle use and
duty cycle in much the same way as diesel fuel.
Since it is consumed during operation of the
vehicle, the DEF tank must be refilled periodi-
cally when indicated by the DEF gauge and
warning messages. The blue filler cap is clearly
marked “Diesel Exhaust Fluid”. On Chassis Cab
