CAUTION
Oil level should be checked regularly. Op-
erating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
For additional information on checking the Cum-
mins 5.0L engine oil level, refer to the “Titan
Diesel Owner’s Manual”.
CHANGING ENGINE OIL
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.
3. Turn the engine off and wait more than 15 minutes.
4. Remove the oil filler cap
Aby turning it
counterclockwise.
5. Place a large drain pan under the drain plug
B.
6. Remove the drain plug
Bwith a wrench by
turning it counterclockwise and completely
drain the oil.
If the oil filter is to be changed, remove and

Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using engine oil and filters
that are not of the specified quality, or exceeding
recommended oil and filter change intervals
could reduce engine life. Damage to the engine
caused by improper maintenance or use of incor-
rect oil and filter quality and/or viscosity is not
covered by the NISSAN New Vehicle Limited
Warranty.
Your engine was filled with a high-quality engine
oil when it was built. You do not have to change
the oil before the first recommended change
interval. Oil and filter change intervals depend
upon how you use your vehicle.
Operation under the following conditions may
require more frequent oil and filter changes:● repeated short distance driving at cold out-
side temperatures
● driving in dusty conditions
● extensive idling
● towing a trailer
● stop and go commuting
For additional information, refer to the “Mainte-
nance and schedules” section of this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and NISSAN A/C
system oil Type S (DH-PS) or the exact
equivalents.

CAUTION
Your vehicle may require more frequent
maintenance if it operates on biodiesel
blends between 6% and 10% (B6 and B10) .
To avoid damage to your vehicle, the oil,
oil filter, and fuel filter will need to be
replaced after a shorter time interval than
if your vehicle was operating on pure
petroleum-based diesel. For additional in-
formation, refer to the “Maintenance” sec-
tion in the “Titan Owner’s Manual.”
CHECKING ENGINE OIL LEVEL
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. 3. Turn off the engine.
Wait more than
10 minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way.
