CAUTION
●Overfilling your DEF tank can cause
damage to the tank.
● DEF will freeze below 12°F (-11°C) ;
however, your vehicle is equipped with
an automatic preheating system, which
allows the DEF system to operate be-
low 12°F (-11°C) . When the vehicle is not
in operation for an extended period of
time with temperatures at or below 12°F (-11°C) , the DEF tank could freeze. In
this condition, adding DEF will not
change the gauge level and added DEF
will not reach the pump, because it will
sit on top of the frozen layer. Move the
vehicle to a warm location to thaw the
DEF completely for the gauge to read
accurately and allow new DEF to reach
the pump. If the tank is overfilled and
freezes, it could be damaged, therefore
do not overfill in sustained cold condi-
tions below 12°F (-11°C) .

NOTE:
The factory fill oil may include a red dye
that is added for manufacturing quality pro-
cesses. The dye makes the oil appear to be
red. This is normal. The red dye will be
flushed from the engine after approxi-
mately 4–5 oil changes.1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature, then turn it off.

7. Refill engine with recommended oil through the oil filler opening, then install the oil filler
cap securely.
For additional information on drain and refill
capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information” sec-
tion of this manual. The drain and refill capacity depends on the
oil temperature and drain time. Use these
specifications for reference only. Always use
the dipstick to determine when the proper
amount of oil is in the engine.
8. Start the engine. Check for leakage around the drain plug and oil filter. Correct as re-
quired.
9. Turn the engine off and wait more than 10 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.

FUEL SYSTEM PRIMING
WARNING
The fuel pump, high-pressure fuel lines,
and fuel rail contain very high-pressure
fuel. To reduce the possibility of personal
injury, never loosen any fittings while the
engine is running.
NOTE: ● It is not necessary to vent air from the
high-pressure fuel system before start-
ing the engine.
● Upon ignition on the electric lift pump
will run until the fuel system is primed
or 90 seconds, whichever comes first. Purge the air out of the fuel system after refilling a
completely empty fuel tank by the following pro-
cedure:
1. Turn the key ON for 90 seconds to prime the fuel system. After 90 seconds, crank the
engine for a maximum of 30 seconds or until
the engine starts. If the engine does not
