maintenance NISSAN TITAN 2008 Repair Manual

If you install snow tires, they must be the same
size, brand, construction and tread pattern on all
four wheels.
For additional traction on icy roads, studded tires
may be used. However, some U.S. states and
Canadian provinces prohibit their use. Check
local, state and provincial laws before installing
studded tires. Skid and traction capabilities of
studded snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on P275/60R20 size tires. Installation of
the tire chains/cables on P275/60R20 size
tires will cause damage to the vehicle. If
you plan to use tire chains/cables, you
should install P265/70R18 size tires on
your vehicle.
Use of tire chains may be prohibited according to
location. Check the local laws before installing
tire chains. When installing tire chains, make sure
they are the proper size for the tires on your
vehicle and are installed according to the chain
manufacturer’s suggestions.Use only SAE
class “S” chains.Class “S” chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” chains are de-signed to meet the minimum clearances between
the tire and the closest vehicle suspension or
body component required to accommodate the
use of a winter traction device (tire chains or
cables) . The minimum clearances are determined
using the factory equipped tire size. Other types
may damage your vehicle. Use chain tensioners
when recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of the
tire chain must be secured or removed to prevent
the possibility of whipping action damage to the
fenders or underbody. If possible, avoid fully load-
ing your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise, your
vehicle may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving with
chains in such conditions can cause damage to
the various mechanisms of the vehicle due to
some overstress.
Use only the 2WD range when driving on clear
paved roads.CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km) .
See “Flat tire” in the “In case of emer-
gency” section in this manual for tire re-
placing procedures.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

The wheel nuts must be kept tight-
ened to specifications at all times. It
is recommended that wheel nuts be
tightened to specification at each
tire rotation interval.
WARNING
cAfter rotating the tires, check and
adjust the tire pressure.
cRetighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.) .
cDo not include the spare tire in

Tire wear and damage
WARNING
cTires should be periodically in-
spected for wear, cracking, bulg-
ing or objects caught in the tread.
If excessive wear, cracks, bulging
or deep cuts are found, the tire(s)
should be replaced.cThe original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
cTires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be ob-
vious. Replace the tires as neces-
sary to prevent tire failure and
possible personal injury.
cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact a NISSAN
dealer.

Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING
cThe use of tires other than those recom-
mended or the mixed use of tires of
different brands, construction (bias,
bias-belted or radial) , or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-
tire clearance, tire chain clearance,
speedometer calibration, headlight aim
and bumper height. Some of these ef-
fects may lead to accidents and could
result in serious personal injury.cIf the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics and/or
interference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear. Re-
fer to “Wheels and tires” in the “Techni-
cal and consumer information” section
of this manual for wheel off-set
dimensions.
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cReplacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.cDo not install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could have
structural damage and could fail with-
out warning.
cThe use of retread tires is not
recommended.
cFor additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Four-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial) , and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears.

If excessive tire wear is found, it is recommended
that all four tires be replaced with tires of the
same size, brand, construction and tread pattern.
The tire pressure and wheel alignment should
also be checked and corrected as necessary.
Contact a NISSAN dealer.
Wheel balance
Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can get
out of balance. Therefore, they should be bal-
anced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
cFor additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet .
Care of wheels
cWash the wheels when washing the vehicle
to maintain their appearance.
cClean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
cDo not use abrasive cleaners when washing
the wheels.
cInspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
cNISSAN recommends waxing the road
wheels to protect against road salt in areas
where it is used during winter.

General information
This information is for Flexible Fuel vehicles (FFV)
only. FFV vehicles can be identified by the fuel
filler door label that states Ethanol (E-85) or
Unleaded Gasoline Only. This section only cov-
ers those subjects that are unique to Flexible Fuel
vehicles.
CAUTION
Only vehicles with the E-85 filler door la-
bel can operate on E-85. Fuel system or
other damage can occur if E-85 is used in
vehicles that are not designed to run on
E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel etha-
nol and 15% unleaded gasoline.
WARNING
cEthanol vapors are extremely flam-
mable and could cause serious per-
sonal injury.
cNever have any smoking materials lit in
or near the vehicle when removing the
fuel filler cap or filling the tank.
cDo not use E-85 as a cleaning agent and
never use it near an open flame.Fuel requirements
Your vehicle will operate on both unleaded regu-
lar gasoline with an octane rating of at least 87
AKI (Anti-Knock Index) number (Research oc-
tane number 91) , or E-85 fuel, or any mixture of
these two.
For the best starting and vehicle driveability re-
sults, do not continually switch between E-85
and unleaded regular gasoline. If you must switch
fuels, NISSAN recommends the following:
cdo not switch when the fuel gauge indicates
less than 1/4 full
cadd more than 5 gallons of fuel
coperate the vehicle immediately after refuel-
ing for a period of at least 5 minutes
NOTE:
When the ambient temperature is above
90°F (32°C) , you may experience hard start-
ing and rough idle following start up even if
the above recommendations are followed.
Starting
The characteristics of E-85 fuel make it unsuit-
able for use when ambient temperatures fall be-
low 0°F (-18°C) . In the range of 0°F (-18°C) to
32°F (0°C) , you may experience an increase in
the time it takes for you engine to start, and adeterioration in drivability (sags and/or hesita-
tions) until the engine is fully warmed up.
Fuel consumption
Because E-85 fuel contains less energy per gal-
lon than gasoline, you will experience an increase
in fuel consumption. You can expect your fuel
mileage to decrease by about 30% compared to
gasoline operation.
Replacement parts
Many components in your Flexible Fuel Vehicle
(FFV) are designed to be compatible with etha-
nol. Always be sure that your vehicle is serviced
with correct ethanol compatible parts.
CAUTION
Replacing fuel system components with
non-ethanol compatible components can
damage your vehicle and may also affect
the warranty coverage.
Maintenance
If you operate your vehicle using E-85 fuel, follow
the correct maintenance log shown in the
“NISSAN Service and Maintenance Guide”.

Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is important
to select the engine oil viscosity based on the
temperatures at which the vehicle will be oper-
ated before the next oil change. Choosing an oil
viscosity other than that recommended could
cause serious engine damage.
Selecting the correct oil filter
Your new NISSAN vehicle is equipped with a
high-quality genuine NISSAN oil filter. When re-
placing, use a genuine NISSAN oil filter or its
equivalent for the reason described in “Change
intervals”.
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 war-
ranty.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:
crepeated short distance driving at cold out-
side temperatures
cdriving in dusty conditions
cextensive idling
ctowing a trailer
cstop and go commuting
Refer to the “NISSAN Service and Maintenance
Guide” for the maintenance schedule.
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 the oil, NISSAN
A/C system oil Type S or the exact equiva-
lents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replace-
ment of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle does not harm the earth’s ozone
layer. Although this refrigerant does not affect the
earth’s atmosphere, certain government regula-
tions require the recovery and recycling of any
refrigerant during automotive air conditioner sys-
tem service. A NISSAN dealer has the trained
technicians and equipment needed to recover
and recycle your air conditioner system refriger-
ant.
Contact a NISSAN dealer when servicing your air
conditioner system.

To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are
clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine over-
loading and/or overheating. However, for
long steep grades, do not stay in 1st gear
when driving above 35 MPH (56 km/h) or
2nd gear when driving above 58 MPH (93
km/h) .
cIf the engine coolant rises to an extremely
high temperature when the air conditioner
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.cTrailer towing requires more fuel than normal
circumstances.
cAvoid towing a trailer for your vehicle’s first
500 miles (805 km) .
cFor the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .
cHave your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
cWhen making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
cCrosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling.
Do the following if the trailer begins to sway:
1. Take your foot off the accelerator pedal to
allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the ve-
hicle– Do not correct trailer sway by steering or
applying the brakes.
2. When the trailer sway stops, gently apply the
brakes and pull to the side of the road in a
safe area.
3. Try to rearrange the trailer load so it is bal-
anced as described earlier in this section.
cBe 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.
cDownshift the transmission to a lower gear
for engine braking when driving down steep
or long hills. This will help slow the vehicle
without applying the brakes.
cTo maintain engine braking efficiency and
electrical charging performance, do not use
overdrive.
cAvoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
cIncrease your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.

cDo not use cruise control while towing a
trailer.
cSome states or provinces have specific
regulations and speed limits for vehicles that
are towing trailers. Obey the local speed
limits.
cCheck your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
cWhen stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
cWhen launching a boat, don’t allow the wa-
ter level to go over the exhaust tail pipe or
rear bumper.
cMake 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, see the
“Maintenance and do-it-yourself” section
earlier in this manual.Tow mode
Tow mode should be used when pulling a heavy
trailer or hauling a heavy load. Press the tow
button to activate the tow mode. The tow indica-
tor in the instrument panel illuminates when the
tow mode is selected. Press the Tow button
again to turn the tow mode OFF. The Tow mode is
automatically cancelled when the key is turned
OFF.
The Tow mode does the following:
cReduces transmissions shifts when pulling a
trailer or hauling a load.
cProvides similar shift feel to driver when the
vehicle is towing.
The Tow mode should be used when the vehicle
and trailer weight is at least 75% of the vehicle’s
GCWR. Tow mode is most useful in the following
driving conditions when towing a heavy trailer or
hauling a heavy load:
cRolling terrain.
cStop and go traffic.
cBusy parking lots.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, see the
“Maintenance and do-it-yourself” section
earlier in this manual.
FLAT TOWING
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.
CAUTION
cFailure to follow these guidelines can
result in severe transmission damage.
cWhenever flat towing your vehicle, al-
ways tow forward, never backward.
