UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. For
additional information, refer to the “Appearance
and care” section of this manual.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir. The following descriptions are provided to give
you a better understanding of the scheduled
maintenance items that should be regularly
checked or replaced. The maintenance schedule
indicates at which mileage/time intervals each
item requires service.
Items marked with
“*”are recommended by
NISSAN for reliable vehicle operation. You are
not required to perform maintenance on these
items in order to maintain the warranties which
come with your NISSAN. Other maintenance
items and intervals are required.
When applicable, additional information can be
found in the “Do-it-yourself” section of this
manual.
NOTE: NISSAN does not advocate the use of
non-OEM approved aftermarket flushing sys-tems and strongly advises against performingthese services on a NISSAN product. Many of theaftermarket flushing systems use non-OEM ap-proved chemicals or solvents, the use of whichhas not been validated by NISSAN.

9-6Maintenance and schedules

countered, have your vehicle checked. It is rec-
ommended that you visit a NISSAN dealer for
servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS (for gas
engine only)
For diesel engine oil and oil filter recommenda-
tions, refer to “Engine oil and oil filter recommen-
dations” section of the “Titan Diesel Owner’s
Manual”.
Selecting the correct oil
It is essential to choose the correct grade, quality
and viscosity engine oil to ensure satisfactory
engine life and performance. For additional infor-
mation, refer to “Recommended fluids/lubricants
and capacities” in this section. NISSAN recom-mends the use of an energy conserving oil in
order to improve fuel economy.
Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE vis-
cosity standard. These oils have the API certifica-
tion mark on the front of the container. Oils which
do not have the specified quality label should not
be used as they could cause engine damage.

the Tire and Loading Information label, refer to
“Tire and Loading Information label” in this sec-
tion, indicates the maximum total weight of pas-
sengers, optional equipment (air conditioning,
trailer hitch, etc) and cargo that your vehicle is
designed to carry.
Before driving a loaded vehicle, confirm that you
do not exceed the GVWR or the GAWR for your
vehicle. Refer to ’’Vehicle Loading Information’’ in
this section for details.
Also check tires for proper inflation pressures.

TRUCK-CAMPER LOADING
INFORMATION
Technical and consumer information10-29

NOTE:
Trailer Sway Assist cannot reduce trailer
sway in all situations.● Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Use the Tow Mode or downshift the trans-
mission to a lower gear for engine braking
when driving down steep or long hills. This
will help slow the vehicle without applying
the brakes.
● Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
● Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
● NISSAN recommends that the cruise con-
trol (if so equipped) not be used while tow-
ing a trailer. ●
Some states or provinces have specific
regulations and speed limits for vehicles that
are towing trailers. Obey the local speed
limits.
● Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after
50 miles (80 km) of travel and at every break.
● When launching a boat, don’t allow the wa-
ter level to go over the exhaust tail pipe or
rear bumper.
● Make sure you disconnect the trailer lights
before backing the trailer into the water or
the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, refer to
the “Do-it-yourself” section in this manual.
Tow mode
Using tow mode is recommended when pulling a
heavy trailer or hauling a heavy load. Press the
TOW MODE switch to activate tow mode. The
indicator light on the TOW MODE switch illumi-
nates when tow mode is selected. Press the
TOW MODE switch again to turn tow mode off.
Tow mode is automatically cancelled when the
ignition switch is turned off. Tow mode includes the following features:
● Grade logic — Adjusts transmission shifts
when pulling a trailer or hauling a load up a
grade.
● Downhill Speed Control (DSC) — automati-
cally downshifts when driving down a grade
with a trailer or heavy load to help control
vehicle speed.
Driving the vehicle in the tow mode with no
trailer/load or light trailer/light load will not cause
any damage. However, fuel economy may be
reduced and the transmission/engine driving
characteristics may feel unusual.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, refer to
the “Maintenance and do-it-yourself” sec-
tion in this manual.FLAT TOWING FOR 2-WHEEL
DRIVE (2WD) VEHICLE (if so
equipped)
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.

WARNING
A vehicle equipped with Four-Wheel Drive
(4WD) should never be tested using a two
wheel dynamometer (such as the dyna-
mometers used by some states for emis-
sions testing) , or similar equipment. Make
sure you inform the test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may re-
sult in transmission damage or unex-
pected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” for an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition” when it
is driven through certain driving patterns. Usually,
the ready condition can be obtained by ordinary
usage of the vehicle. If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready” condition. Before taking the
I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Place the ignition switch in the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20 sec-
onds and then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not blink
after 20 seconds, the I/M test condition is
“ready”. It is recommended that you visit a
NISSAN dealer to set the “ready condition” or to
prepare the vehicle for testing.

Preventive maintenance is the easiest and least
expensive type of maintenance. Keep records of
regularly scheduled maintenance and follow the
maintenance schedule recommendations out-
lined in the “Titan Owner’s Manual”.
Use the correct fuel, lubricating oil, and coolant in
your engine. Blending engine oil with fuel is pro-
hibited for engines with an aftertreatment system.
For additional information refer to the “Capacities
and Specifications” section in this manual.
A NISSAN dealership knows your vehicle. When
you require any service or have any questions,
they will be glad to assist you with the extensive
resources available to them.
DIESEL ENGINE OPERATION
The operation of the diesel engine in your new
vehicle varies from the operation of traditional
gasoline engines found in other vehicles. Read-
ing this supplement will familiarize you and other
operators of the vehicle with the unique mainte-
nance and operating procedures that will prolong
the life of the diesel engine and related systems.
ENGINE BREAK-IN
RECOMMENDATIONS
●Warm up the engine before operating it un-
der load
● Do not operate the engine at idle for ex-
tended periods
● Prevent engine lugging by selecting the ap-
propriate transmission gear
● Monitor the vehicle oil pressure and tem-
perature gauges
● Check fluid levels frequently (Oil & Coolant)
● Vary the throttle position at highway speeds
when carrying weight or towing
NOTE:
Extended light or no load operation will
extend the time before the engine reaches
its full efficiency. If the engine is operated
in this manner, reduced fuel economy and
power may be observed.
The aforementioned procedure should be ob-
served for the first 6,000 miles. The engine run-in
is improved by operating the vehicle under load.
DIESEL FUEL SYSTEM
The diesel engine fuel system is a pressurized
two-stage filtration system and consists of: ● A frame-mounted primary (stage 1) fuel filter
containing water/fuel separator, electric fuel
pump, and water in fuel drain valve
● An engine-mounted secondary (stage 2)
fuel filter
● A fuel injector for each cylinder (8 total)
● A high-pressure fuel pump
● A high-pressure fuel rail for each cylinder
bank (2 total)
● High-pressure fuel lines from the high-
pressure fuel pump to the right bank fuel rail,
right bank fuel rail to the left bank fuel rail,
and fuel rails to fuel injectors.
The stage 1 fuel filter separates water and filters
impurities from the fuel. The stage 2 fuel filter
filters finer impurities from the diesel fuel. The
stage 1 and stage 2 fuel filters should be
changed at the recommended service interval or
when indicated by the information display. For
additional information, refer to the “Titan Owner’s
Manual”.
