engine NISSAN FRONTIER 2014 D23 / 3.G Workshop Manual

There is an OFF position between the
LOCK and ON positions. The OFF position
is indicated by a “1” on the ignition switch.
When the ignition is in the OFF position,
the steering wheel is not locked (for mod-
els with a steering lock mechanism) .
In order for the steering wheel to be locked, it
must be turned about 1/8 of a turn clockwise
from the straight up position.
To lock the steering wheel, turn the key to
the LOCK position. Remove the key. To
unlock the steering wheel, insert the key
and turn it gently while rotating the steer-
ing wheel slightly right and left.
If the key will not turn from the LOCK posi-
tion, turn the steering wheel to the left or
right while turning the key to unlock the key
cylinder.
MANUAL TRANSMISSION (if so
equipped)
The ignition switch includes a device that helps
prevent accidental removal of the key while driv-
ing.
The key can only be removed when the ignition
switch is in the LOCK position.
On manual transmission models, to turn the igni-
tion switch to the LOCK position from the ACC or
ON position, place the ignition switch in the OFF
position, push the key in, then place the ignition
switch in LOCK position.
KEY POSITIONS

NISSAN VEHICLE IMMOBILIZER
SYSTEM (if so equipped)
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 and clutch fluid (if so equipped) ,
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 headrests.
● Adjust inside and outside mirrors.
● Fasten the seat belt and ask all passengers
to do likewise.
● Check the operation of warning lights when
the key is turned to the ON (3) position. See
“Warning/indicator lights and audible re-
minders” in the “Instruments and controls”
section of this manual. 1. Apply the parking brake.
2.
Automatic transmission:
Move the shift lever to P (Park) or N (Neu-
tral) . P (Park) is recommended.
The shift lever cannot be moved out of
the P (Park) position and into any of
the other gear positions if the ignition
switch is placed in the OFF position or
if the key is removed from the ignition
switch.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
Manual transmission:
Move the shift lever to N (Neutral) . Depress
the clutch pedal to the floor while cranking
the engine.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.

proximately 1/3 to the floor) and hold it
and then crank the engine. Release the
key and 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.
Crank the engine for 5-6 seconds. After
cranking the engine, release the accel-
erator pedal. Crank the engine with your
foot off the accelerator pedal by plac-
ing the ignition in the START position.
Release the key when the engine starts. 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, turn the key off and wait 10 sec-
onds before cranking again, otherwise the
starter could be damaged.
4. 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.
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.

equipped)
WARNING
●Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , D (Drive) , 3, 2 or 1.
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.
Coasting with the transmission in the N
(Neutral) position may cause serious
damage to the transmission.
● Do not downshift abruptly on slippery
roads. This may cause a loss of control.
DRIVING THE VEHICLE

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,
the steering wheel will be locked unless the igni-
tion switch is placed in the ON position (for
models with a steering lock mechanism) . 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 in the LOCK posi- tion and remove the key.
2. Apply the parking brake.
3. Remove the shift lock release cover as shown.
4. Use a protective cloth on the tip of a small screwdriver before inserting it in the shift
lock release slot and pushing down.
5. Move the shift lever to the N (Neutral) posi- tion while holding down the shift lock re-
lease.
6. Place the ignition switch in the ON position to unlock the steering wheel (for models with

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 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.
Overdrive switch (if so equipped)
Each time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and theshift lever in the D (Drive) position,
the transmission upshifts into Over-
drive as vehicle speed increases.
Overdrive does not engage until the engine
has reached operating temperature.
OFF: For driving up and down longslopes where engine braking is nec-
essary push the Overdrive switch
once. The O/D OFF indicator light
in the instrument panel comes on at
this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable shift
shocks as the transmission shifts into and out of
Overdrive repeatedly. In this case, depress the
Overdrive switch to turn the Overdrive off. The
O/D OFF indicator light in the instrument panel
comes on at this time.
When driving conditions change, depress the
Overdrive switch to turn the Overdrive on.
Remember not to drive at high speeds for ex-
tended periods of time with the Overdrive off.
This reduces fuel economy.
