sensor NISSAN PATHFINDER 2017 R52 / 4.G Service Manual

●When excessively heavy baggage is loaded
in the rear seat or cargo area of your vehicle.
The ICC system is designed to automatically
check the sensor’s operation within the limita-
tions of the system.
The detection zone of the ICC sensor is limited. A
vehicle ahead must be in the detection zone for
the vehicle-to-vehicle distance detection mode
to maintain the selected distance from the vehicle
ahead.
A vehicle ahead may move outside of the detec-
tion zone due to its position within the same lane
of travel. Motorcycles may not be detected in the
same lane ahead if they are traveling offset from
the centerline of the lane. A vehicle that is enter-
ing the lane ahead may not be detected until the
vehicle has completely moved into the lane.
If this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime. The driver may have to
manually control the proper distance away
from vehicle traveling ahead. When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the ICC sensor may detect
vehicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may cause
the ICC system to decelerate or accelerate the
vehicle.
The detection of vehicles may also be affected by
vehicle operation (steering maneuver or traveling
position in the lane, etc.) or vehicle condition.If this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime unexpectedly. You will
have to manually control the proper dis-
tance away from the vehicle traveling
ahead.

Action to take
When the conditions listed above are no longer
present, turn the system off using the ICC
CRUISE ON/OFF switch. Turn the ICC system
back on to use the system.
Condition B
When the radar sensor area of the front bumper
is covered with dirt or is obstructed, the ICC
system will automatically be canceled. If the sen-
sor area is covered with ice, a transparent or
translucent vinyl bag, etc., the ICC system may
not detect vehicles ahead. In these instances, the
ICC system may not cancel and may not be able
to maintain the selected following distance from
the vehicle ahead. Be sure to check and clean the
sensor area.
The system warning light (orange) will illuminate
and the “Unavailable: Front Radar Obstruction”
warning message will appear in the vehicle infor-
mation display.
When driving on roads with limited road struc-
tures or buildings (for example, or long bridges,
deserts, snow fields, driving next to long walls) ,
the system may illuminate the system warning
light (orange) and display the “Unavailable: Front
Radar Obstruction” message.Action to take
If the warning light (orange) comes on, park the
vehicle in a safe location and turn the engine off.
Check to see if the radar sensor window is
blocked. If the radar sensor window is blocked,
remove the blocking material. Restart the engine.
If the warning light continues to illuminate, have
the ICC system checked. It is recommended that
you visit a NISSAN dealer for this service.
Condition C
When the ICC system is not operating properly, a
chime sounds and the system warning light (or-
ange) will come on.Action to take
If the warning light comes on, park the vehicle in a
safe place. Turn the engine off, restart the engine,
resume driving and set the ICC system again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the
system is malfunctioning. Although the ve-
hicle is still drivable under normal condi-
tions, have the vehicle checked. It is recom-
mended that you visit a NISSAN dealer for
this service.

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes 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
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates 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 vehicle
checked. It is recommended that you visit a
NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above3-6mph(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 ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation 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 operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional 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 driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle 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 per-
form 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 output
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 condi-
tions:
– Understeer (vehicle tends to not follow the steered path despite increased steer-
ing 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 cannot prevent loss of
vehicle control in all driving situations.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
Starting and driving5-69

●The system is designed as an aid to the
driver in detecting large stationary ob-
jects to help avoid damaging the ve-
hicle. The system will not detect small
objects below the bumper, and may not
detect objects close to the bumper or
on the ground.
● If your vehicle sustains damage to the
rear bumper fascia, leaving it mis-
aligned or bent, the sensing zone may
be altered causing inaccurate measure-
ment of obstacles or false alarms.
The RSS sounds a tone to warn the driver of
obstacles near the rear bumper when the shift
lever is in R (Reverse) . The system may not
detect objects at speeds above 3 mph (5 km/h)
and may not detect certain angular or moving
objects.
The RSS detects obstacles up to 5.9 ft (1.8 m)
from the rear bumper with a decreased coverage
area at the outer corners of the bumper (refer to
the illustration for approximate zone coverage
areas) . As you move closer to the obstacle, the
rate of the tone increases. When the obstacle is
less than 10 in (25.0 cm) away, the tone will
sound continuously. If the RSS detects a station-
ary or receding object further than 10 in.
(25.0 cm) from the side of the vehicle, the tone will sound for only 3 seconds. Once the system
detects an object approaching, the tone will
sound again.
The RSS automatically turns on when the shift
lever is placed in R (Reverse) and the ignition
switch is placed in the ON position. The RSS can
be turned off in the vehicle information display.
For additional information, refer to “Vehicle infor-
mation display” in the “Instruments and controls”
section of this manual. To turn the RSS off, the
ignition switch must be placed in the ON posi-
tion.
Keep the RSS sensors (located on the rear bum-
per fascia) free from snow, ice and large accumu-
lations of dirt (do not clean the sensors with sharp
objects) . If the sensors are covered, it will affect
the accuracy of the RSS.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole, or use the NISSAN Intelligent Key®.
ANTIFREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
antifreeze to assure proper winter protection. For
additional information, refer to “Engine cooling
system” in the “Do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For additional information, refer to “Bat-
tery” in the “Do-it-yourself” section of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For additional information, refer to “Changing
engine coolant” in the “Do-it-yourself” section of
this manual.
COLD WEATHER DRIVING
5-74Starting and driving

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It monitors
tire pressure of all tires except the spare. When
the low tire pressure warning light is lit, and the
“Tire Pressure Low - Add Air” warning appears in
the vehicle information display, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will acti-
vate and warn you of it by the low tire pressure
warning light. This system will activate only when
the vehicle is driven at speeds above 16 mph
(25 km/h). For additional information, refer to
“Warning lights, indicator lights and audible re-
minders” in “Instruments and controls” section
and the “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” sections of
this manual.
WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
● If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal in-
jury. Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible. ●
Since the spare tire is not equipped with
the TPMS, when a spare tire is mounted
or a wheel is replaced, tire pressure will
not be indicated, the TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit a NISSAN dealer for these services.
● Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
