46 STARTING AND OPERATING
1 — Diesel Fuel Fill Location
2 — Diesel Exhaust Fluid (DEF) Fill Location
CAUTION!
It is extremely important to avoid any contamination of
the diesel fuel with Diesel Exhaust Fluid (DEF). Ensure
that the diesel fuel filler cap is in place and completely
tightened before opening or filling the DEF.
1. Remove cap from DEF filler neck (located on drivers
side of the vehicle in the fuel door).
2. Insert DEF fill adapter/nozzle into DEF tank filler neck.
CAUTION!
• To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not "top off" the DEF
tank after filling.
• DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, how-
ever, if the tank is overfilled and freezes, the system
could be damaged.
• When DEF is spilled, clean the area immediately
with water and use an absorbent material to soak up
the spills on the ground.
• Do not attempt to start your engine if DEF is acci-
dentally added to the diesel fuel tank as it can result
in severe damage to your engine, including but not
limited to failure of the fuel pump and injectors.
• Never add anything other than DEF to the tank –
especially any form of hydrocarbon such as diesel fuel,
fuel system additives, gasoline, or any other
petroleum-based product. Even a very small amount of
these, less than 100 parts per million or less than 1 oz.
