engine NISSAN FRONTIER 2006 D22 / 1.G Service Manual

When installing a CB, ham radio or car phone in
your NISSAN, be sure to observe the following
cautions, otherwise the new equipment may ad-
versely affect the engine control system and
other electronic parts.
WARNING
cA cellular telephone should not be used
while driving so full attention may be
given to vehicle operation. Some juris-
dictions prohibit the use of cellular tele-
phones while driving.
cIf you must make a call while your ve-
hicle is in motion, the hands free cellu-
lar phone operational mode (if so
equipped) is highly recommended. Ex-
ercise extreme caution at all times so
full attention may be given to vehicle
operation.
cIf a conversation in a moving vehicle
requires you to take notes, pull off the
road to a safe location and stop your
vehicle before doing so.
CAUTION
cKeep the antenna as far away as pos-
sible from the electronic control
modules.
cKeep the antenna wire more than 8 in
(20 cm) away from the electronic con-
trol system harnesses. Do not route the
antenna wire next to any harness.
cAdjust the antenna standing-wave ratio
as recommended by the manufacturer.
cConnect the ground wire from the CB
radio chassis to the body.
cFor details, consult a NISSAN dealer.
cDo not ground electrical accessories
directly to the battery terminal. Doing
so, will bypass the variable voltage con-
trol system and the vehicle battery may
not charge completely. Refer to “Vari-
able voltage control system” in the
“Maintenance and do-it-yourself” sec-
tion later in this manual.
cUse electrical accessories with the en-
gine running to avoid discharging the

WARNING
cDo not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
cProperly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
cDo not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death.cIf you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
cDo not run the engine in closed spaces
such as a garage.
cDo not park the vehicle with the engine
running for any extended length of time.
cKeep the lift gate and rear windows
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
the lift gate or rear windows open, fol-
low these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton (if so equipped) to off and the fan
control dial to 4 (high) to circulate
the air.
cIf electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the lift gate or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle.cThe exhaust system and body should be
inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of
the exhaust system.
d. You have had an accident involving
damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
cThe exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.

cDo not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
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.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
underinflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly underinflated tire causes the tire to over-
heat and can lead to tire failure. Underinflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Additional information:
cThe TPMS does not monitor the tire pres-
sure of the spare tire.

DRIVING SAFETY PRECAUTIONS
Your NISSAN is designed for both normal and
off-road use. However, avoid driving in deep wa-
ter or mud as your NISSAN is mainly designed for
leisure use, unlike a conventional off-road ve-
hicle.
Remember that two-wheel drive models are less
capable than four-wheel drive models for rough
road driving and extrication when stuck in deep
snow or mud, or the like.
Please observe the following precautions:
WARNING
cDrive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving
over rough terrain.
cDo not drive across steep slopes. In-
stead drive either straight up or straight
down the slopes. Off-road vehicles can
tip over sideways much more easily
than they can forward or backward.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. Never
back down in N (Neutral) or with the
clutch depressed (manual transmission
vehicles) , using only the brake, as this
could cause loss of control.
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. Use the Hill
Descent Control feature (if so
equipped) .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.
cAlways drive with the floor mats in
place as the floor may become hot.

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.cMake sure the area around the vehicle is
clear.
cCheck fluid levels such as engine oil, cool-
ant, brake fluid, and window washer fluid as
frequently as possible, or at least whenever
you refuel.
cCheck that all windows and lights are clean.
cVisually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
cLock all doors.
cPosition seat and adjust head restraints.
cAdjust inside and outside mirrors.
cFasten seat belts and ask all passengers to
do likewise.
cCheck 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.
