check engine light NISSAN ARMADA 2021 Owner´s Manual

— When your vehicle or the ve-hicle or pedestrian ahead
moves quickly or significantly
such that the system cannot
detect and react in time (for
example, pedestrian moving
quickly toward the vehicle at
close range, vehicle cutting in,
changing lanes, making a
turn, steering abruptly, sud-
den acceleration or decelera-
tion).
— When the vehicle or pedes- trian is offset from the vehi-
cle’s forward path.
— If the speed difference be- tween the two vehicles is
small.
— The pedestrian’s profile is par- tially obscured or unidentifi-
able; for example, due to
transporting luggage, push-
ing a stroller, wearing 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 after starting the engine
— If the vehicle ahead has a unique or unusual shape, ex-
tremely low or high clearance
heights, or unusual cargo
loading or is narrow (for ex-
ample, a motorcycle).
— When the vehicle or pedes- trian is located near a traffic
sign, a reflective area (for ex-
ample, water on road), or is in
a shadow.
— When multiple pedestrians are grouped together.
— When the view of the pedes- trian is obscured by a vehicle
or other object.
— While towing a trailer or other vehicle.
. The system performance may be
degraded in the following condi-
tions:
— 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 auto-
matically check the sensor (radar
and camera)’s functionality, with-
in certain limitations. The system
may not detect some forms of
obstruction of the sensor area
such as ice, snow or stickers, for
example. In these cases, the sys-
tem 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 condi-
tions, the AEB with pedestrian
detection system may unexpect-
edly apply partial braking. When
acceleration is necessary, de-
press the accelerator pedal to
override the system.
. The AEB with pedestrian detec-
tion system may operate when a
pattern, object, shadow or lights
are detected that are similar to
the outline of vehicles or pedes-
trians, or if they are the same size
and position as a vehicle or mo-
torcycle’s tail lights.

SYSTEM MAINTENANCE
The sonar sensorsare located on the
rear bumper. Observe the following items
to ensure proper operation of the system:
. Always keep the sonar sensors clean.
. If the sonar sensors are dirty, wipe
them off with a soft 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 objects obstructing
the area around the sonar sensors. .
Do not subject the area around the
sonar sensors to strong impact. Also,
do not remove or disassemble the
sonar sensors. If the sonar sensors
and peripheral areas are deformed in
an accident, etc., have the sonar
sensors checked. It is recommended
that you visit a NISSAN dealer for this
service.
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint on
the sonar sensors and their surround-
ing areas. This may cause a malfunc-
tion 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 sonar sensors.

5-144Starting and driving
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 you
visit a NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 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 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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.
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 con-
trol 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 condi-
tions).
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.
When the VDC system operates, the VDC
warning 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 indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is
off. When the VDC switch is used to turn
off the system, the VDC system still
operates to prevent one drive wheel from
slipping by transferring power to a non
slipping drive wheel. The VDC warning
light
flashes if this occurs. All other
VDC functions are off, and the VDC
warning light
will not flash. The VDC
system is automatically reset to on when
the ignition switch is placed in the OFF
position then back to the ON position.
When the 4L position is selected with the
4WD shift switch, the VDC system is
disabled and the VDC off indicator light
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

5-146Starting and driving
SIC4455
VEHICLE DYNAMIC CONTROL (VDC)
OFF SWITCH
The vehicle should be driven with the
Vehicle Dynamic Control (VDC) system ON
for most driving conditions.
When the vehicle is stuck in mud or snow,
the VDC system reduces the engine out-
put to reduce wheel spin. The engine
speed will be reduced even if the accel-
erator is depressed to the floor. If max-
imum engine power is needed to free a
stuck vehicle, turn the VDC system off.
To turn off the Vehicle Dynamic Control
(VDC) system, push the VDC OFF switch.
The VDC off indicator light
will
illuminate. Push the VDC OFF switch again or restart
the engine to turn ON the system.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing,
apply deicer through the key hole. If the
lock becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check antifreeze to assure
proper winter protection. For additional
information, see “Engine cooling system”
(P.8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P.8-11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).
COLD WEATHER DRIVING

To shut off the engine in an emergency
situation while driving, perform the fol-
lowing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less
than 1.5 seconds, or
. Push and hold the push-button igni-
tion switch for more than 2 seconds.TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (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 the vehicle is being driven with low tire
pressure, the TPMS will activate 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 more details, see “Low
tire pressure warning light” (P.2-15) and
“Tire Pressure Monitoring System (TPMS)”
(P.5-5).
WARNING
.If the low tire pressure warning
light illuminates or Low Pressure
information is displayed on the
monitor screen while driving,
avoid sudden steering maneu-
vers or abrupt braking, reduce
vehicle speed, pull off the road
to a safe location and stop the
vehicle as soon as possible. Driv-
ing 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 ser-
ious personal injury. Check the
tire pressure for all four tires.
Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low
tire pressure warning light OFF. If
the light still illuminates while
driving after adjusting the tire
pressure, a tire may be flat. 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, the TPMS will not
function and the low tire pressure
warning light will flash for ap-
proximately 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 you
visit a NISSAN dealer for these
services.
