2023 NISSAN PATHFINDER brake sensor

BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert,
drive safely and be in control of the ve-
hicle at all times. The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions:
• Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power
is transferred to a non-slipping drive
wheel on the same axle.
• Controls brake pressure and engine out- put to reduce drive wheel slip based on
vehicle speed (traction control function).
• Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:– Understeer (vehicle tends to not follow the steered path despite increased
steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to
maintain control of the vehicle, but it can-
not prevent loss of vehicle control in all driv-
ing situations. When the VDC system operates, the
indicator light in the instrument panel
flashes so note the following:
• The road may be slippery or the system
may determine some action is required
to help keep the vehicle on the steered
path.
• You may feel a pulsation in the brake pedal and hear a noise or vibration from
under the hood. This is normal and indi-
cates that the VDC system is working
properly.
• Adjust your speed and driving to the road conditions.
For additional information, see “Slip indica-
tor light” (P. 2-21) and “Vehicle Dynamic Con-
trol (VDC) OFF indicator light” (P. 2-21).
If a malfunction occurs in the system, the
andindicator lights come on in
the instrument panel. The VDC system au-
tomatically turns off when these indicator
lights are on.
The vehicle information display is used to
turn off the VDC system. The
indicator
light and the AEB with Pedestrian Detec-
tion system warning light illuminate to in-
dicate the VDC and AEB with Pedestrian
Detection systems are off.

WARNING
• Never rely solely on the hill start as-
sist system to prevent the vehicle
from moving backward on a hill. Al-
ways drive carefully and attentively.
Depress the brake pedal when the
vehicle is stopped on a steep hill. Be
especially careful when stopped on a
hill on frozen or muddy roads. Failure
to prevent the vehicle from rolling
backwards may result in a loss of
control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and
may result in a collision or serious
personal injury.
• The hill start assist may not prevent
the vehicle from rolling backwards
on a hill under all load or road condi-
tions. Always be prepared to depress
the brake pedal to prevent the ve-
hicle from rolling backwards. Failure
to do so may result in a collision or
serious personal injury. The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backward in the
time it takes the driver to release the brake
pedal and apply the accelerator when the
vehicle is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
• The shif t lever is moved to a forward or
reverse gear.
• The vehicle is stopped completely on a hill by applying the brake.
The maximum holding time is 2 seconds.
Af ter 2 seconds the vehicle will begin to roll
back and hill start assist will stop operating
completely.
Hill start assist will not operate when the
shif t position is moved to N (Neutral) or P
(Park), or on a flat and level road. The sonar system sounds a tone to inform
the driver of obstacles around the vehicle
using the sonar sensors located in the
front and rear bumpers..
When the sonar system is turned on, the
sonar view will automatically appear in the
vehicle information display.
WARNING
• The sonar system is a convenience
but it is not a substitute for proper
parking.

•The driver is always responsible for
safety during parking and other ma-
neuvers. Always look around and
check that it is safe to do so before
parking.
• Read and understand the limitations
of the sonar system as contained in
this section. The colors of the corner
sonar indicator indicates different
distances to the object.
• Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck's compressed-air
brakes or a pneumatic drill may af-
fect the function of the system; this
may include reduced performance or
a false activation.
• The sonar system is designed as an
aid to the driver in detecting large
stationary objects to help avoid
damaging the vehicle.
• The sonar system is not designed to
prevent contact with small or moving
objects. Always move slowly. The
system will not detect small objects
below the bumper, and may not de-
tect objects close to the bumper or
on the ground. •
The sonar system may not detect the
following objects: fluff y objects such
as snow, cloth, cotton, glass, wool,
etc.; thin objects such as rope, wire
and chain, etc.; or wedge-shaped
objects.
If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles or false alarms.
CAUTION
• Excessive noise (such as audio sys-
tem volume or an open vehicle win-
dow) will interfere with the tone and
it may not be heard.
• Keep the sonar sensors (located on
the bumper fascias) free from snow,
ice and large accumulations of dirt.
Do not clean the sensors with sharp
objects. If the sensors are covered,
the accuracy of the sonar function
will be diminished.
SYSTEM OPERATION

• 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
Starting and driving5-189

•If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information
on wheel off-set dimensions, see
“Wheels and tires” (P. 10-10).
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor. •
When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a
NISSAN dealer for ID registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
• Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.Four-wheel drive models
CAUTION
• Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), and tread pattern on
all four wheels. Failure to do so may
result in a circumference difference
between tires on the front and rear
axles which will cause excessive tire
wear and may damage the transmis-
sion and the drivetrain parts.
• Only use the spare tire specified for
your vehicle.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. It is recom-
mended that you visit a NISSAN dealer for
this service.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Do-it-yourself8-41

Doors and engine hood:Check that the
doors and engine hood operate properly.
Also ensure that all latches lock securely.
Lubricate hinges, latches, latch pins, rollers
and links if necessary. Make sure that the
secondary latch keeps the hood from
opening when the primary latch is
released.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch fully open. If the hood, trunk, or rear
hatch is not held open, have the gas stays
or struts replaced.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Rotate tires at the specified
interval shown in the maintenance
schedule. Tires*:
Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
tire pressure sensor: It is recommended
that you replace the TPMS tire pressure
sensor assembly when the tires are re-
placed due to wear or age.
Wheel alignment and balance: If the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may
be a need for wheel alignment. If the steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield: Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind- shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to
http://collision.nissanusa.com.
Windshield wiper blades*:
Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
