check engine NISSAN PATHFINDER 2023 Workshop Manual

–The braking force becomes poor
due to wet brakes af ter driving
through a puddle or washing the
vehicle.
• Turn the RAB system off in the follow-
ing conditions to prevent the occur-
rence of an unexpected accident re-
sulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed
truck.
– The vehicle is on the chassis
dynamometer.
– The vehicle drives on an uneven
road surface.
– The vehicle is towing an object (if
so equipped).
– Suspension parts other than
those designated as Genuine
NISSAN parts are used. (If the ve-
hicle height or the vehicle body in-
clination is changed, the system
may not detect an obstacle
correctly.)
– If the vehicle is using an accessory
like a bike rack, or cargo carrier
that blocks the sensors. •
Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “Mal-
function” warning message will appear in
the vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure
proper operation of the system:
• Always keep the parking sensors
O1
clean.
• If the parking sensors are dirty, wipe them off with a sof t cloth while being careful to
not damage them.

5-136Starting and driving

–When the vehicle, pedestrian or
cyclist is offset from the vehicle’s
forward path.
– If the speed difference between
the two vehicles is small.
– The pedestrian’s profile is par-
tially obscured or unidentifiable;
for example, due to transporting
luggage, pushing a stroller, wear-
ing bulky or very loose-fitting
clothing or accessories, or being
in a unique posture (such as rais-
ing hands).
– There is poor contrast of a person
to the background, such as having
clothing color or pattern which is
similar to the background.
– For approximately 15 seconds af-
ter starting the engine.
– If the vehicle ahead has a unique
or unusual shape, extremely low
or high clearance heights, or un-
usual cargo loading or is narrow
(for example, a motorcycle).
– When the vehicle, pedestrian or
cyclist is located near a traffic
sign, a reflective area (for ex-
ample, water on road), or is in a
shadow. –
When multiple pedestrians or cy-
clists are grouped together.
– When the view of the pedestrian
or cyclist is obscured by a vehicle
or other object.
– While towing a trailer or other
vehicle.
• The system performance may be de-
graded in the following conditions:
– The vehicle is driven on a slippery
road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is
loaded in the rear seat or the
cargo area of your vehicle.
• The system is designed to automati-
cally check the sensor’s (radar and
camera) functionality, within certain
limitations. The system may not de-
tect some forms of obstruction of the
sensor area such as ice, snow or
stickers, for example. In these cases,
the system may not be able to warn
the driver properly. Be sure that you
check, clean and clear sensor areas
regularly. •
In some road and traffic conditions,
the AEB with Pedestrian Detection
system may unexpectedly apply par-
tial braking. When acceleration is
necessary, depress the accelerator
pedal to override the system.
• The AEB with Pedestrian Detection
system may operate when a pattern,
object, shadow or lights are detected
that are similar to the outline of ve-
hicles, pedestrians or cyclists, or if
they are the same size and position
as a vehicle or motorcycle’s tail
lights.
• The system may keep operating
when the vehicle ahead is turning
right or lef t.
• The system may operate when your
vehicle is approaching and passing a
vehicle ahead.
• Depending on the road shape
(curved road, entrance and exit of the
curve, winding road, lane regulation,
under construction, etc.), the system
may operate temporarily for the on-
coming vehicle in front of your
vehicle.

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to ob-
tain maximum engine performance
and ensure the future reliability and
economy of your new vehicle. Failure to
follow these recommendations may
result in shortened engine life and re-
duced engine performance.
• Avoid driving for long periods at constant speed, either fast or slow, and do not run
the engine over 4,000 rpm.
• Do not accelerate at full throttle in any gear.
• Avoid quick starts.
• Avoid hard braking as much as possible.
• Do not tow a trailer for the first 500 miles (805 kilometers). Your engine, axle or
other parts could be damaged.

• 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.

The “Tire Size Incorrect” warning may be
displayed if there is a large difference be-
tween the diameters of front and rear
wheels and tires. Pull off the road in a safe
area, with the engine idling. Check that all
tire sizes, brand, construction and tread
pattern are the same, that the tire pressure
is correct and that the tires are not exces-
sively worn. If you have any problems,
please change tires or adjust the correct
tire pressure. Do not select the SNOW, MUD/
RUT, or SAND modes with the Drive Mode
Selector and do not drive fast.
If any warning message continues to be
displayed, have your vehicle checked. It isrecommended that you visit a NISSAN
dealer as soon as possible.
WARNING
• For 4WD equipped vehicles, do not
attempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or per-
sonal injury.
• Do not attempt to test an 4WD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamom-
eters used by some states for emis-
sions testing) or similar equipment
even if the other two wheels are
raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with
4WD before it is placed on a dyna-
mometer. Using the wrong test
equipment may result in drivetrain
damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal
injury.
CAUTION
• Do not operate the engine on a free
roller when any of the wheels are
raised.
• The powertrain may be damaged if
you continue driving with the “AWD
Error” warning on.
• If the warning message remains on
af ter the above operation, have your
vehicle checked as soon as possible.
It is recommended that you visit a
NISSAN dealer for this service.
• If the “AWD Error” warning appears
while driving, there may be a mal-
function in the 4WD system.
Reduce the vehicle speed and have
your vehicle checked as soon as pos-
sible. It is recommended that you visit a
NISSAN dealer for this service.
When the vehicle is in the P (Park) position,
the operation noise may be heard from the
lower part of the vehicle. This is not a
malfunction.

CURB
OC:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the ignition switch in the LOCK position.
NOTE:
Use the Idling Stop System when the ve-
hicle is stopped for a period of time, for
example waiting at stop lights. Stop the
engine with the ignition switch when
parking, etc. for an extended period of
time.
WARNING
• If the engine is not running or is
turned off while driving, the power
assist for the steering will not work.
Steering will be harder to operate.
• When the electric power steering
warning light illuminates with the
engine running, there will be no
power assist for the steering. You will
still have control of the vehicle, but
the steering will be harder to operate.
Have the power steering system
checked. It is recommended that you
visit a NISSAN dealer for this service.
The power steering system is designed to
provide power assist while driving to oper-
ate the steering wheel with light force.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and protect it from getting
damaged. While the power assist is re-
duced, steering wheel operation will be-
come heavy. When the temperature of the
power steering system goes down, the
power assist level will return to normal.
Avoid repeating such steering wheel op- erations that could cause the power steer-
ing system to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the electric power steering warning light
illuminates while the engine is running, it
may indicate the power steering system is
not functioning properly and may need
servicing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the electric power steering warning
light illuminates with the engine running,
there will be no power assist for the steer-
ing, but you will still have control of the
vehicle. At this time, greater steering effort
is required to operate the steering wheel,
especially in sharp turns and at low speeds.
For additional information, see “Electric
Power steering warning light” (P. 2-17).
POWER STEERING
5-174Starting and driving

•Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
– When installing a spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, see “Tire and
Loading Information label”
(P. 8-30).
– For additional information, see
“Wheels and tires” (P. 8-28).
The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (ABS) in-
cludes 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 mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates 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 ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov
e3-6mph(5-10
km/h). The speed varies according to road
conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
5-176Starting and driving

If the chassis control system error warning
message appears in the vehicle informa-
tion display, it may indicate that the ARC is
not functioning properly. Have the system
checked as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
WARNING
The ARC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively.
When the ARC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
ARC is operating properly. You may also feel
deceleration when the ARC is operating.
However, this is not a malfunction.
WARNING
• Never rely solely on the hill descent
control system to control vehicle
speed when driving on steep down-
hill grades. Always drive carefully and
attentively when using the hill de-
scent control system and decelerate
the vehicle speed by depressing the
brake pedal if necessary. Be espe-
cially careful when driving on frozen,
muddy or extremely steep downhill
roads. Failure to control vehicle
speed may result in a loss of control
of the vehicle and possible serious
injury or death.
• The hill descent control may not con-
trol the vehicle speed on a hill under
all load or road conditions. Always be
prepared to depress the brake pedal
to control vehicle speed. Failure to do
so may result in a collision or serious
personal injury. The hill descent control system helps
maintain vehicle speed when driving under
15 mph (25 km/h) on steeper downhill
grades. Hill descent control is useful when
engine braking alone cannot control ve-
hicle speed. Hill descent control applies the
vehicle brakes to control vehicle speed al-
lowing the driver to concentrate on steer-
ing while reducing the burden of brake and
accelerator operation. The hill descent
control system will only work in the Sand
and Mud/Rut mode.
If the hill descent control system ON indica-
tor light is blinking, the hill descent control
is engaged; however, the hill descent con-
trol will not control the vehicle speed.
• Once the system is activated, the indica-
tor light will remain on in the instrument
panel. For additional information, see “Hill
descent control system ON indicator
light” (P. 2-18).
If the accelerator or brake pedal is de-
pressed while the hill descent control sys-
tem is on, the system will stop operating
temporarily. As soon as the accelerator or
brake pedal is released, the hill descent
control system begins to function again if
the hill descent control operating condi-
tions are fulfilled.
