2012 NISSAN TITAN check engine light

If:1. The engine coolant temperature is not re- duced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure low/engine coolant temperature high warning light
illumi-
nates, this may indicate a malfunction. Move
the vehicle off the road in a safe area and
allow the engine to cool. If after checking the
oil and coolant, the
remains on, do not
continue to drive and call a NISSAN dealer.
The malfunction indicator light (MIL) may also
come ON. If onlyit remains on, you do not need
to have your vehicle towed, but have it inspected
soon by a NISSAN dealer. See “Malfunction in-
dicator light (MIL)” in the “Instruments and con-
trols ” section of this manual.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
If the vehicle cannot maintain a safe driv-
ing speed, pull to the side of the road in a
safe area. Allow the engine to cool and
return to normal operation. See “If your
vehicle overheats” in the “In case of emer-
gency” section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
AUTOMATIC TRANSMISSION
WARNING
● Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , or L (Low) . Always
depress the brake pedal until shifting is
completed. Failure to do so could cause
you to lose control and have an
accident.
● Cold engine idle speed is high, so use
caution when shifting into a forward or
reverse gear before the engine has
warmed up.
● Never shift to P (Park) or R (Reverse)
while the vehicle is moving. This could
cause an accident.
● Except in an emergency, do not shift to
the N (Neutral) position while driving.
Doing so can cause a loss of engine
braking which may result in a collision,
serious personal injury or death. In ad-
dition, coasting with the transmission
in the N (Neutral) position may cause
serious damage to the transmission.

To push the shift lock release, complete the fol-
lowing procedure:1. Turn the ignition key to the LOCK position and remove the key
2. Apply the parking brake.
3. On vehicles equipped with a column shifter, tilt the steering wheel down to the lowest
position.
4. Remove the shift lock release cover as shown. 5. Use a protective cloth on the end of a small
screwdriver before inserting it in the shift
lock release slot and pushing down.
6. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
7. For models without the NISSAN vehicle im- mobilizer system, turn the key to the ON
position to unlock the steering wheel.
8. Now the vehicle may be moved to the de- sired location.
If the shift selector cannot be moved out of P
(Park) , have a NISSAN dealer check the auto-
matic transmission system as soon as possible.
WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, please note
that the transmission will be locked in any of the
forward gears according to the condition.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, turn the ignition
switch OFF and wait for 3 seconds. Then
turn the ignition switch back to the ON
position. The vehicle should return to its
normal operating condition. If it does not
return to its normal operating condition,
have a NISSAN dealer check the transmis-
sion and repair it if necessary.

●When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
● For vehicles equipped with
, use 4H
or 4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
WARNING
● For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
CAUTION
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the shift selector to the N (Neu-
tral) position with the brake pedal
depressed, and shift the 4WD shift
switch to 2WD.
● If the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.

4WD shift indicator light
The 4WD shift indicator light is located in the
vehicle information display.
The light should turn off within 1 second after
turning the ignition switch to the ON position.
While the engine is running, the 4WD shift indi-
cator light will illuminate the position selected by
the 4WD shift switch.● The 4WD shift indicator light may blink
while shifting from one drive mode to
the other. When the shifting is com-
pleted, the 4WD shift indicator light
will come on. ●
If the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
● If the 4WD shift indicator light indica-
tion changes to 2WD when the 4WD
shift switch is shifted to the 4H position
at low ambient temperatures, the 2WD
mode may be being engaged due to
malfunctioning drive system. If the indi-
cator does not return to normal and the
4WD warning light comes on, have the
system checked by the nearest NISSAN
dealer.
4WD warning light
Warning light Comes on or blinks

Comes on There is a mal-
function in the4–wheel drive system
Blinks
slowly The difference in
wheel rotation is large
The 4WD warning light is located in the meter. The 4WD warning light comes on when the key
switch is turned to ON. It turns off soon after the
engine is started.
If any malfunction occurs in the 4WD system
when the key switch is ON, the warning light will
either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
shift indicator light goes out.
A large difference between the diameters of front
and rear wheels will make the warning light blink
slowly (about once per two seconds) . Change
the 4WD shift switch into 2WD and do not drive
fast.
CAUTION
●
If the warning light comes on or blinks
slowly during operation or rapidly after
stopping the vehicle for a while, have
your vehicle checked by a NISSAN
dealer as soon as possible.
● Shifting between 4H and 4LO is not
recommended when the 4WD warning
light turns on.

●When the warning light comes on, the
2WD mode may be engaged even if the
4WD shift switch is in 4H. Be especially
careful when driving. If corresponding
parts are malfunctioning, the 4WD
mode will not be engaged even if the
4WD shift switch is shifted.
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the automatic transmission
shift selector to the N position with
the brake pedal depressed, and shift
the 4WD shift switch to 2WD.
● If the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.
● The transfer case may be damaged if
you continue driving with the warning
light blinking. The E-Lock system can provide additional trac-
tion and should only be used when a vehicle has
become or is becoming stuck. This system oper-
ates by electronically “locking” the two rear drive
wheels together, allowing them to turn at the
same speed. The system is used when it is not
possible to free a stuck vehicle even when using
the 4LO position (4 wheel drive vehicles) .
When added traction is required, activate the
E-Lock system by pushing the switch ON. See
“Electronic locking rear differential (E-Lock) sys-
tem switch” in the “Instruments and Controls”
section. Once the system fully engages, the indi-
cator light in the instrument panel will remain ON.
When the system is activated, both rear wheels
will engage, providing added traction.
The rear wheels may momentarily slip or move to
engage the system, and the system will only
engage up to approximately 4 MPH (7 km/h) .
Once the vehicle is free, the system should be
turned OFF and driving resumed.
The Anti-Lock Brake (ABS) system is disabled
and the ABS light illuminates when the E-Lock
system is ON. Also, the Vehicle Dynamic Control
(VDC) system is disabled and the VDC light
illuminates when the E-Lock system is ON.
WARNING
●
Never leave the E-Lock system ON
when driving on paved or hard-surfaced
roads. Turning the vehicle may result in
the rear wheels slipping and result in an
accident and personal injury. After us-
ing the E-Lock system to free the ve-
hicle, turn the system OFF.
● Use the E-Lock system only when free-
ing a stuck vehicle. Try the 4LO position
before using the E-Lock system. Never
use the E-Lock system on a slippery
road surface such as snow or ice sur-
face. Using the E-Lock system when
driving in these road conditions may
cause unexpected movement of the ve-
hicle during engine braking, accelerat-
ing or turning, which may result in an
accident and serious personal injury.

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) . The speed varies according to road
conditions.
When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.●
ABLS system uses automatic braking to
transfer power from a slipping drive wheel to
the wheel on the same axle with more trac-
tion. The ABLS system applies braking to
the slipping wheel, which helps redirect
power to the other wheel.
● On 4WD models the ABLS system operates
in both 4H and 4LO modes. If 4WD mode is
engaged, the ABLS system operates for
both drive axles. On 2WD vehicles, the
ABLS system operates on the drive axle
only.
● The ABLS system is always ON. In some
conditions, the system may automatically
turn the ABLS system off. If the system is
automatically turned off, normal brake func-
tion will continue. ABLS will function even
when the VDC system is turned OFF.
● The ABLS does not operate if both wheels
on a drive axle are slipping.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, and the CHECK
TIRE PRESSURE warning appears in the vehicle
information display, one or more of your tires is
significantly under-inflated. If equipped, the sys-
tem 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. If the vehicle is being driven with low tire
pressure, the TPMS will activate and warn you of
it by the low tire pressure warning light. This
system will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h) . For
more details, refer to “Warning/indicator lights
and audible reminders” in the “Instruments and
controls” section, “Tire pressure information” in
the “Display screen, heater, air conditioner, audio
and phone systems” section and “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section.
WARNING
●If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury. Check the tire pressure for
all four tires. Adjust the tire pressure to
the recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible.
● When 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. ●
Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift selector to P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
