2016 NISSAN TITAN check engine

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedures:1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK position, and wait approximately 10 sec-
onds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid, DEF (Diesel only) and
windshield-washer fluid as frequently as
possible, or at least whenever you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Check that all doors are closed.
● Position seat and adjust head
restraints/headrests.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is placed in the ON posi-
tion. For additional information, refer to
“Warning lights, indicator lights and audible
reminders” in the “Instruments and controls”
section of this manual. 1. Apply the parking brake.
2. Move the shift lever to P (Park) or N (Neu-
tral) . P (Park) is recommended.
The starter is designed not to operate
unless the shift lever is in either P
(Park) or N (Neutral) .
3. Push the ignition switch to the ON position. Depress the brake pedal and push the igni-
tion switch to start the engine.
To start the engine immediately, push and
release the ignition switch while depressing
the brake pedal with the ignition switch in
any position.
● If the engine is very hard to start in ex-
tremely cold weather or when restarting,
depress the accelerator pedal a little (ap-
proximately 1/3 to the floor) and while
holding, crank the engine. Release the
accelerator pedal when the engine starts.
● If the engine is very hard to start because
it is flooded, depress the accelerator
pedal all the way to the floor and hold it.
Push the ignition switch to the ON posi-
tion to start cranking the engine. After five
or six seconds, stop cranking by pushing
the ignition switch to LOCK. After crank-
ing the engine, release the accelerator
pedal. Crank the engine with your foot off
BEFORE STARTING THE ENGINE STARTING THE ENGINE (gasoline engine only)
5-14Starting and driving

the accelerator pedal by depressing the
brake pedal and pushing the push-button
ignition switch to start the engine. If the
engine starts, but fails to run, repeat the
above procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, push the ignition switch to the
OFF position and wait 10 seconds before
cranking again, otherwise the starter
could be damaged.4. Warm-up
Allow the engine to idle for at least 30 sec-
onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather. In cold weather, keep the en-
gine running for a minimum of two to three
minutes before shutting it off. Starting and
stopping the engine over a short period of
time may make the vehicle more difficult to
start.
5. To stop the engine, shift the shift lever into the P (Park) position and push the ignition
switch to the OFF position. In preparation for the next engine start, the engine
may have a slightly delayed shutoff after placing
the ignition switch in the OFF position, depend-
ing on the driving conditions.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
REMOTE START (if so equipped)
Vehicles started with the remote start require the
ignition switch to be placed in the ON position
before the shift lever can be moved from the P
(Park) position. To place the ignition switch to the
ON position, follow these steps: 1. Make sure that the Intelligent Key is on you.
2. Apply the brake. 3. Push the ignition switch once to the ON
position.
For additional information, refer to “NISSAN In-
telligent Key®” in the “Pre-driving checks and
adjustments” section of this manual.

Shift lock release
If the battery is discharged, the shift lever may not
be moved from the P (Park) position even with the
brake pedal depressed.
To move the shift lever, release the shift lock. The
shift lever can be moved to N (Neutral) . However,
for models without the NISSAN Vehicle Immobi-
lizer System, the steering wheel will be locked
unless the ignition switch is turned to the ON
position. This allows the vehicle to be moved if
the battery is discharged.To push the shift lock release, complete the fol-
lowing procedure:
1. Place the ignition switch to the LOCK posi- tion.
2. Apply the parking brake.
3. Remove the shift lock release cover. If a screwdriver is used to remove the cover, it
should be wrapped in a protective cloth to
prevent damage to the cover and surround-
ing plastic.
4. Insert a small object or finger in the shift lock release slot and push.
5. Move the shift lever to the N (Neutral) posi- tion while holding the shift lock release.
6. Now the vehicle may be moved to the de- sired location.
If the shift lever cannot be moved out of P (Park) ,
have the automatic transmission system checked
as soon as possible. It is recommended that you
visit a NISSAN dealer for this service.
WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.
Accelerator downshift
— in D (Drive) 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 the transmission checked and re-
paired, it if necessary. It is recommended
that you visit a NISSAN dealer for this ser-
vice.

●Keep your engine tuned up.
● Follow the recommended scheduled main-
tenance.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
● For vehicles equipped with
, use 4H
or 4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
● Use the recommended viscosity engine oil.
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
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 or vehicle in-
formation display warning message
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 lever to the N (Neutral)
position with the brake pedal de-
pressed, and shift the 4WD shift
switch to 2WD.
