2004 NISSAN TITAN check engine

2. If the brake fluid level is correct, have the
brake system checked by a NISSAN dealer.
WARNING
cYour brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it
to be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driv-
ing it could be dangerous.
cPressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
cIf the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at a
NISSAN dealer.
Charge warning light
If this light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and check
the generator belt. If the belt is loose, broken,
missing, or if the light remains on, see a NISSAN
dealer immediately.
CAUTION
Do not continue driving if the generator
belt is loose, broken or missing.
Door open warning light
This light comes on when any of the doors are not
closed securely while the ignition key is in the ON
position.
Engine oil pressure
low/Engine coolant tempera-
ture high warning light
This light warns of low engine oil pressure or high
engine coolant temperature.
If the light flickers or comes on during normal
driving, pull off the road in a safe area, stop the
engine and allow it to cool. If the light remains on
after checking the oil and coolant, stop the en-
gineimmediatelyand call a NISSAN dealer or
other authorized repair shop.
This light is not designed to indicate a low
oil or low coolant level.Check the oil level
with the dipstick and check the coolant level on
the reservoir. See “Engine oil” and “Checking
engine coolant level” in the “Maintenance and
do-it-yourself” section of this manual. Also see “If
your vehicle overheats” in the “In case of emer-
gency” section of this manual.
CAUTION
cRunning the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
cIf the gauge indicates engine coolant
temperature over the normal range,
stop the vehicle as soon as safely pos-
sible. If the engine is overheated, con-
tinued operation of the vehicle may se-
riously damage the engine. See “If your
vehicle overheats” in the “In case of
emergency” section for immediate ac-
tion required.

the fuel filler cap is installed and closed tightly,
and that the vehicle has at least 3 gallons of fuel
in the fuel tank.
After a few driving trips, the
lamp should
turn off if no other potential emission control
system malfunction exists.
Operation
The malfunction indicator lamp will come on in
one of two ways:
cMalfunction indicator lamp on steady — An
emission control system malfunction has
been detected. Check the fuel filler cap. If
the fuel filler cap is loose or missing, tighten
or install the cap and continue to drive the
vehicle. The
lamp should turn off after
a few driving trips. If thelamp does
not turn off after a few driving trips, have the
vehicle inspected by a NISSAN dealer. You
do not need to have your vehicle towed to
the dealer.
cMalfunction indicator lamp blinking — An
engine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– do not drive at speeds above 45 MPH
(72 km/h) .– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo
being hauled or towed.
The malfunction indicator lamp may stop blinking
and come on steady. Have the vehicle inspected by
a NISSAN dealer. You do not need to have your
vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Security indicator light (NVIS)
(if so equipped)
This light blinks whenever the ignition switch is in
the LOCK, OFF or ACC position. This function
indicates the security system equipped on the
vehicle is operational.
For additional information, see “Security system”
later in this section.
Slip indicator light (if so
equipped)
This indicator light will blink when the traction
control system is limiting wheel spin. Slippery
road conditions may exist if the slip indicator
blinks on. If this happens, adjust your driving
accordingly.
The slip indicator light also comes on when you
turn the ignition key to the ON position. The light
will turn off after about 2 seconds if the system is
operational. If the light does not come on or go
off, have the traction control system checked by a
NISSAN dealer.

If the 4WD shift switch is set in the 4LO position
and the light blinks, stop the vehicle, drive slowly
forward and the light will turn on.
When you shift between 4H and 4LO, stop the
vehicle, move the automatic transmission selec-
tor lever to the N (Neutral) position with the brake
pedal depressed, then push the 4WD shift
switch and move it to 4LO or 4H.
The transfer case may be damaged if you shift the
switch while driving.
You cannot move the transfer 4WD shift switch
between 4H and 4LO unless you have first
stopped the vehicle and moved the automatic
transmission shift selector lever to N (Neutral)
with the brake pedal depressed. Make sure the
transfer 4LO position indicator light turns on
when you shift the 4WD shift switch to 4LO.
The indicator light may blink while shifting
from one drive mode to the other.
Turn signal/hazard indicator
lights
The appropriate light flashes when the turn signal
switch is activated.
Both lights flash when the hazard switch is turned
on.
Vehicle dynamic control off
indicator light (if so equipped)
This indicator light comes on when the vehicle
dynamic control off switch is pushed to OFF. This
indicates the vehicle dynamic control system is
not operating.
Push the vehicle dynamic control off switch again
or restart the engine and the system will operate
normally. See “Vehicle dynamic control (VDC)
system” in the “Starting and driving” section of
this manual.
The vehicle dynamic control light also comes on
when you turn the ignition key to the ON position.
The light will turn off after about 2 seconds if the
system is operational. If the light stays on or
comes on along with the SLIP indicator light
while you are driving, have the vehicle dynamic
control system checked by a NISSAN dealer.
While the vehicle dynamic control system is op-
erating, you might feel slight vibration or hear the
system working when starting the vehicle or ac-
celerating, but this is normal.
AUDIBLE REMINDERS
Brake pad wear warning
The front disc brake pads have audible wear
warnings. When a front brake pad requires re-
placement, it makes a high pitched scraping
sound when the vehicle is in motion, whether or
not the brake pedal is depressed. Have the
brakes checked as soon as possible if the warn-
ing sound is heard.
Key reminder chime
A chime sounds if the driver’s door is opened
while the key is left in the ignition switch. Remove
the key and take it with you when leaving the
vehicle.

The front seats are warmed by built-in heaters (if
so equipped) .
1. Start the engine.
2. Push the
(low) or(high) posi-
tion of the switch, as desired, depending on
the temperature. The indicator light in the
switch will illuminate.
The heater is controlled by a thermostat,
automatically turning the heater on and off.
The indicator light will remain on as long as
the switch is on.
3.
When the seat is warmed or before you leave
the vehicle, be sure to turn the switch off.
CAUTION
cDo not use the seat heater for extended
periods or when no one is using the
seat.
cDo not put anything on the seat which
insulates heat, such as a blanket, cush-
ion, seat cover, etc. Otherwise, the seat
may become overheated.
cDo not place anything hard or heavy on
the seat or pierce it with a pin or similar
object. This may result in damage to the
heater.
cAny liquid spilled on the heated seat
should be removed immediately with a
dry cloth.
cWhen cleaning the seat, never use
gasoline, benzine, thinner, or any simi-
lar materials.
cIf any abnormalities are found or the
heated seat does not operate, turn the
switch off and have the system checked
by your NISSAN dealer.
cThe battery could run down if the seat
heater is operated while the engine is
not running.The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most driv-
ing conditions.
If the vehicle is stuck in mud or snow, the VDC
system reduces the engine output to reduce
wheel spin. The engine speed will be reduced
even if the accelerator is depressed to the floor. If
maximum engine power is needed to free a stuck
vehicle, turn the VDC system off.
To turn off the VDC system, push the VDC OFF
switch. The
indicator will come on.
Push the VDC OFF switch again or restart the

CAUTION
cDo not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo not push or tow your vehicle to start
the engine.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than passen-
ger cars to make them capable of performing in a
variety of on-pavement and off-road applications.
This gives them a higher center of gravity than
ordinary cars. An advantage of higher ground
clearance is a better view of the road, allowing
you to anticipate problems. However, they are not
designed for cornering at the same speeds as
conventional two-wheel drive vehicles any more
than low-slung sports cars are designed to per-
form satisfactorily under off-road conditions. If at
all possible, avoid sharp turns at high speeds. As
with other vehicles of this type, failure to operate
this vehicle correctly may result in loss of control
or vehicle rollover. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt.
Be sure to read the driving safety precautions
later in this section.
LOW TIRE PRESSURE WARNING
SYSTEM
This vehicle is equipped with the low tire pres-
sure warning system. It monitors tire pressure of
all tires except the spare. When the tire pressure
monitoring system warning light it lit, one or more
of your tires is significantly underinflated. If
equipped, the system also displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel.
The low tire pressure warning system will activate
only when the vehicle is driven at speeds above
20 MPH (32 km/h) . Also, this system may not
detect a sudden drop in tire pressure (for ex-
ample a flat tire while driving) .
Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and the
outside temperature. Low outside temperature
can lower the temperature of the air inside the tire
which can cause a lower tire inflation pressure.
This may cause the low tire pressure warning
light to illuminate.
If the warning light illuminates in low ambient
temperature as described above, check the tire
pressure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure shown

cMany hills are too steep for any vehicle.
If you drive up them, you may stall. If
you drive down them, you may not be
able to control your speed. If you drive
across them, you may roll over.
cDo not shift gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
cStay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an
accident.
cIf your engine stalls or you cannot make
it to the top of a steep hill, never at-
tempt to turn around. Your vehicle
could tip or roll over. Always back
straight down in R (Reverse) gear and
apply brakes to control your speed.
cHeavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
cUnsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.cTo avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so
equipped) and evenly distribute the
load. Secure heavy loads in the cargo
area as far forward and as low as pos-
sible. Do not equip the vehicle with tires
larger than specified in this manual.
This could cause your vehicle to roll
over.
cDo not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move sud-
denly and injure your hands. Instead
drive with your fingers and thumbs on
the outside of the rim.
cBefore operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
cLower your speed when encountering
strong crosswinds. With a higher center
of gravity, your NISSAN is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
cDo not drive beyond the performance
capablity of the tires, even with 4WD
engaged.cAccelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
cIf at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your NISSAN four-wheel drive vehicle
has a higher center of gravity than a
two-wheel drive vehicle. The vehicle is
not designed for cornering at the same
speeds as conventional two-wheel
drive vehicles. Failure to operate this
vehicle correctly could result in loss of
control and/or a rollover accident.
cAlways use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial) , and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
cBe sure to check the brakes immedi-
ately after driving in mud or water. See
“Brake system” later in this section for
“Wet brakes”.
cAvoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
