2. Remove the diesel fuel filler cap by rotating it counterclockwise.

Fuel and Diesel Exhaust Fluid (DEF) Fill Location

3. Fully insert the diesel nozzle into the filler pipe. Fill the vehicle with fuel.
4. When the 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 nozzle.
5. Remove the diesel nozzle, reinstall fuel cap and close the fuel filler door.
NOTE:
When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap about a quarter turn
until you hear one click. This is an indication that
the cap is properly tightened.
If the fuel filler cap is not tightened properly, the
MIL will come on. Be sure the cap is tightened
every time the vehicle is refueled.
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 368.
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 370.
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.
System Overview
This vehicle is equipped with a Diesel Exhaust Fluid
(DEF) injection system and a Selective Catalytic
Reduction (SCR) catalyst to meet the emission
requirements.

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.
