check engine light NISSAN TITAN 2008 Owner's Guide

Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
E–85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square, orange
and black label with the common abbreviation or
the appropriate percentage for that region.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
Many of these additives intended for gum, varnish
or deposit removal may contain active solvents or
similar ingredients that can be harmful to the fuel
system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If youdetect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have a NISSAN dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
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.
CAUTION
cYour vehicle is not designed to run on
E-85 fuel. Using E-85 fuel in a vehicle
not specifically designed for E-85 fuel
can damage fuel system components
and is not covered by the NISSAN new
vehicle limited warranty.cE-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded
gasoline.
cU.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.
FLEXIBLE FUEL VEHICLE (FFV) FUEL
RECOMMENDATION (if so equipped)
Your vehicle is designed to use (E-85) Fuel Etha-
nol, “Regular” unleaded regular gasoline or any
percentage of the two fuels combined.
U.S. government regulations require Fuel
Ethanol dispensing pumps to have a small,
square, orange and black label with the
common abbreviation or the appropriate
percentage for that region.
CAUTION
Use of other fuels such as Fuel Methanol
may cause powertrain damage or a loss of
vehicle performance.

Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if it
has an abnormal nose-up or nose-down
condition; check for improper tongue load,
overload, worn suspension or other possible
causes of either condition.
cAlways secure items in the trailer to prevent
load shift while driving.
cKeep the cargo load as low as possible in
the trailer to keep the trailer center of gravity
low.
cLoad the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half. Also make sure the load is
balanced side to side.
cCheck your hitch, trailer tire pressure, ve-
hicle tire pressure, trailer light operation, and
trailer wheel lug nuts every time you attach a
trailer to the vehicle.
cBe certain your rearview mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.cDetermine the overall height of the vehicle
and trailer so the required clearance is
known.
Trailer towing tips
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.
cAlways secure items in the trailer to prevent
load shift while driving.
cLock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadvert-
ently becoming unlatched.
cAvoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
cWhen backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and
back up slowly. If possible, have someone
guide you when you are backing up.Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:
CAUTION
If you move the shift selector lever to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill
side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly
release the brake pedal until the blocks ab-
sorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Make sure the
indicator light (if so
equipped) indicates the transfer case is in
4H, 4L, or 2H and that the ATP light is off. If
the
indicator light is flashing, or the
ATP light is ON, make sure the transmission
is in P (Park) (AT) and turn the 4WD switch
to 2WD or 4H. See9Automatic transmission
park warning light9in the9Instruments and
controls9section and9Using four wheel
drive9in the9Starting and driving9section.
7. Turn off the engine.

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.

If you believe that your vehicle has a de-
fect which could cause a crash or could
cause injury or death, you should immedi-
ately inform the National Highway Traffic
Safety Administration (NHTSA) in addi-
tion to notifying NISSAN.
If NHTSA receives similar complaints, it
may open an investigation, and if it finds
that a safety defect exists in a group of
vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot be-
come involved in individual problems be-
tween you, your dealer, or NISSAN.
To contact NHTSA, you may call the Ve-
hicle Safety Hotline toll-free at 1-888-
327-4236 (TTY: 1-800-424-9153); go
to http://www.safercar.gov; or write to:
Administrator, NHTSA, 400 Seventh
Street, SW., Washington, D.C. 20590.
You can also obtain other information
about motor vehicle safety from
http://www.safercar.gov.
You may notify NISSAN by contacting our
Consumer Affairs Department, toll-free, at
1-800-NISSAN-1.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. Turn the ignition switch ON without starting
the engine. If the Malfunction Indicator Light
(MIL) comes on steady for 20 seconds 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”. If the
MIL indicates the vehicle is in a “not ready” con-
dition, drive the vehicle through the following
pattern to set the vehicle to the ready condition. If
you cannot or do not want to perform the driving
pattern, a NISSAN dealer can conduct it for you.WARNING
Always drive the vehicle in a safe and
prudent manner according to traffic con-
ditions and obey all traffic laws.
1. Start the engine when the engine coolant
temperature gauge needle points to C. Al-
low the engine to idle until the gauge needle
points between the C and H (normal oper-
ating temperature) .
2. Accelerate the vehicle to 55 MPH (88
km/h) , then quickly release the accelerator
pedal completely and keep it released for at
least 10 seconds.
3. Quickly depress the accelerator pedal for a
moment, then drive the vehicle at a speed of
53 - 60 MPH (86 - 96 km/h) for at least 9
minutes.
4. Stop the vehicle.
5. Accelerate the vehicle to 35 MPH (55 km/h)
and maintain the speed for 20 seconds.
6. Repeat steps 4 through 5 at least 10 times.
7. Accelerate the vehicle to 55 MPH (88 km/h)
and maintain the speed for at least 3 min-
utes.
