STARTING AND OPERATING 167
2. Remove the fuel cap by rotating it counterclockwise.
Fuel and Diesel Exhaust Fluid (DEF) Fill Location
3. Fully insert the fuel nozzle into the filler pipe.
4. Fill the vehicle with fuel.
NOTE:
When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
Wait five seconds before removing the fuel nozzle
to allow excess fuel to drain from the nozzle.
5. Remove the fuel nozzle, reinstall fuel cap and close
fuel filler door.
NOTE:
Tighten the fuel filler cap about a quarter turn until you
hear one click. This is an indication that the cap is properly
tightened.
AVOID USING CONTAMINATED FUEL
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper
maintenance of the engine fuel filter and fuel tank is
essential see
Ú page 321.
BULK FUEL STORAGE — DIESEL FUEL
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with water
will promote the growth of “microbes.” These microbes
form “slime” that will clog the fuel filtration system and
lines. Drain condensation from the supply tank and
change the line filter on a regular basis.
NOTE:
When a diesel engine is allowed to run out of fuel, air is
pulled into the fuel system.
If the vehicle will not start see
Ú page 323.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic
Reduction (SCR) system to meet the very stringent diesel
emissions standards required by the Environmental
Protection Agency.
The purpose of the SCR system is to reduce levels of NOx
(oxides of nitrogen emitted from engines) that are harmful
to our health and the environment to a near-zero level. A
small quantity of Diesel Exhaust Fluid (DEF) is injected into
the exhaust upstream of a catalyst where, when
vaporized, it converts smog-forming nitrogen oxides (NOx)
into harmless nitrogen (N2) and water vapor (H2O), two
natural components of the air we breathe. You can
operate with the comfort that your vehicle is contributing
to a cleaner, healthier world environment for this and
generations to come.

2 — DEF Filler
CAUTION!
For diesel engines, only use diesel fuel for motor
vehicles in accordance with ASTM D-975 Grade S15
specifications. The use of other products or mixtures
may damage the engine beyond repair and
consequently void the warranty, due to the damage
caused. If you accidentally introduce other types of fuel
into the tank, do not start the engine. Empty the tank. If
the engine has been run for even an extremely limited
amount of time, you must not only drain the fuel tank,
but the rest of the supply circuit as well.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
