Fuel NISSAN PATHFINDER 2023 Service Manual

Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1.Use Smooth Accelerator and Brake
Pedal Application
• Avoid rapid starts and stops.
• Use smooth, gentle accelerator and brake application whenever possible.
• Maintain constant speed while com- muting and coast whenever possible.
2. Maintain Constant Speed
• Look ahead to try and anticipate and minimize stops.
• Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops.
• Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
• Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load.
• Above 40 mph (64 km/h), it is more efficient to use A/C to cool the vehicle
due to increased aerodynamic drag. • Recirculating the cool air in the cabin
when the A/C is on reduces cooling
load.
4. Drive at Economical Speeds and
Distances
• Observing the speed limit and not ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
• Maintaining a safe following distance behind other vehicles reduces unnec-
essary braking.
• Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
• Select a gear range suitable to road conditions.
5. Use Cruise Control
• Using cruise control during highway driving helps maintain a steady speed.
• Cruise control is particularly effective in providing fuel savings when driving
on flat terrains.
6. Plan for the Shortest Route
• Utilize a map or navigation system to determine the best route to save time. 7.
Avoid Idling
• Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
• Automated passes permit drivers to use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting.
9. Winter Warm Up
• Limit idling time to minimize impact to fuel economy.
• Vehicles typically need no more than 30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving.
• Your vehicle will reach its ideal operat- ing temperature more quickly while
driving versus idling.
10. Keeping your Vehicle Cool
• Park your vehicle in a covered parking area or in the shade whenever
possible.
• When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS
5-170Starting and driving

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• 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.
• Use the recommended viscosity engine oil. For additional information, see “Engine
oil and oil filter recommendations”
(P. 10-7).
If any malfunction occurs in the I-4X4 sys-
tem while the engine is running, messages
are displayed in the meter.
If the “AWD error” warning appears, there
may be a malfunction in the I-4X4 system.
Reduce vehicle speed and have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer as soon as possible. The “AWD High Temp. Stop Vehicle” (high
temperature) warning appears when the
oil temperature of the powertrain parts will
increase due to the difference in rotation
between the front and rear wheels is large
(wheel slip), such as when driving the ve-
hicle on rough roads, through sand or mud,
or freeing a stuck vehicle. If this warning is
displayed, stop the vehicle with the engine
idling, as soon as it is safe to do so. In these
cases, the 4WD changes to 2WD to protect
the powertrain parts. Then if the warning
turns off, you continue 4WD driving.

• If the sonar sensors are dirty, wipe themoff with a sof t cloth while being careful to
not damage them.
• The sonar sensors may be blocked by temporary ambient conditions such as
splashing water, mist or fog. The blocked
condition may also be caused by objects
such as ice, frost or dirt obstructing the
sonar sensors. Check for and remove ob-
jects obstructing the area around the so-
nar sensors.
• Do not subject the area around the sonar sensors to strong impact. Also, do not
remove or disassemble the sonar sen-
sors. If the sonar sensors and peripheral
areas are deformed in an accident, etc.,
have the sonar sensors checked by a
NISSAN dealer.
• Do not attach stickers (including trans- parent material), install accessories or
apply additional paint on the sonar sen-
sors and their surrounding areas. This
may cause a malfunction or improper
operation.
• When washing the vehicle using a high- pressure washer, do not apply direct
washer pressure on the sonar sensors.
This may cause a malfunction of the so-
nar sensors. The Idling Stop System activates to prevent
unnecessary fuel consumption, exhaust
emissions and noise.
• When you stop the vehicle, the engine is
turned off automatically.
• When you release the brake pedal to be- gin moving again, the engine is turned on
automatically.
WARNING
The engine restarts if the vehicle
moves at approximately 1 mph (2
km/h) or more (on a downhill grade,
etc.) while the engine is turned off by
the Idling Stop System. Depress the
brake pedal immediately to stop the
vehicle to prevent an accident.
CAUTION
At the end of the journey the engine
must be stopped and ignition switch be
pushed off. Lock the vehicle as normal.
Pushing the ignition switch off will shut
down all electrical systems. Failure to
do this may result in a discharged
battery.
NOTE:
The Idling Stop System will not activate
under the following conditions:
• When the vehicle is in TOW mode.
• When the engine is kept idling without
the vehicle being driven af ter the en-
gine is turned on.
• When the engine coolant temperature
is low.
• When the battery capacity is low.
• When the battery temperature is low.
• When the vehicle is moving.
• When a negative pressure booster
decreases.
• When the engine hood is opened with
the engine running.
• When the engine is turned on with the
engine hood open.
• When the driver’s seat belt is not
fastened.
• When the driver’s door is open.
• When the steering wheel is operated.
• When the Idling Stop System indicator
blinks at a low speed.
• When the fan speed control is in any
position other than “OFF,” (0) while the
air flow control is in the front defroster
position.
IDLING STOP SYSTEM

CAUTION
• NEVER remove dirt, sand or other de-
bris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner
or broom.
• Never allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle as this
may damage them.
Chemicals used for road surface de-icing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be
cleaned periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended that you visit a
NISSAN dealer.
7-8Appearance and care

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
•
Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Push the park but-
ton to shif t to the P (Park) position.
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
• It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle.
• Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning, even if the ignition switch is
in the OFF position and the engine is
not running. To avoid injury, always
disconnect the negative battery
cable before working near the fan.
• If you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
• Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
•
Because the fuel lines on gasoline en-
gine models are under high pressure
even when the engine is off, it is recom-
mended that you visit a NISSAN dealer
for service of the fuel filter or fuel lines.
CAUTION
• Do not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
•
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other ve- hicle fluids can damage the environ-
ment. Always conform to local regula-
tions for disposal of vehicle fluid.
•
Never leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shif t to
other positions.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, see
“Owner’s Manual/Service Manual order in-
formation” (P. 10-38).
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

WARNING
• Operating the engine with the air
cleaner filter off can cause you or
others to be burned. The air cleaner
filter not only cleans the intake air, it
also stops the flame if the engine
backfires. If the air cleaner is not in-
stalled and the engine backfires, you
could be burned. Never drive with the
air cleaner filter off. Be cautious
working on the engine when the air
cleaner is off. •
Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
To remove the filter from the air cleaner,
push the tabs
OAand pull the cover
upward.
The dry paper type filter element may be
cleaned and reused. Replace the air filter
according to the maintenance log shown
in the "Maintenance and schedules" sec-
tion of this manual.
When replacing the air filter, wipe the inside
of the air cleaner housing and the cover
with a damp cloth.
NOTE:
Af ter installing a new air cleaner, make
sure the air cleaner cover is seated in
the housing and latch the clips
OA.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information, see "Main-
tenance and schedules" section of this
manual for change intervals.
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.

that the wipers and washer operate prop-
erly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery* (for maintenance free batter-
ies): This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec- tronic accessories that consume bat-
tery power when the engine is not
running (Phone chargers, 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.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.

minutes for the oil to drain back into the oil
pan.
9-4Maintenance and schedules

Exhaust system:Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, see “Exhaust gas (carbon monox-
ide)” (P. 5-4).
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
fuel fumes are evident, check for the cause
and have it corrected immediately.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections. Underbody:
The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust may form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P. 7-2).
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, see “Gen-
eral maintenance” (P. 9-2).
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
