service NISSAN ARMADA 2021 Owner´s Manual

CAUTION
.Do not drive the vehicle in the 4HI
or 4LO position on dry hard sur-
face roads. Driving on dry, hard
surfaces in 4HI or 4LO may cause
unnecessary noise, tire wear and
increased fuel consumption.
If the Four-Wheel Drive (4WD)
warning light turns on when driv-
ing on dry hard surface roads:
— in the 4HI position, shift the
4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmis-
sion lever to the N (Neutral)
position with the brake pedal
depressed and shift the 4WD
shift switch to AUTO.
If the 4WD warning light is still
on after the above operation,
have your vehicle checked as
soon as possible. It is recom-
mended you visit a NISSAN
dealer for this service.
. The transfer case may be da-
maged if you continue driving
with the 4WD warning light blink-
ing. See “On-pavement and off-road driving
precautions” (P.5-9) for other precautions
for off-road driving.
NISSAN ALL-MODE 4WD® SYSTEM
The all mode 4WD system provides 3
positions (AUTO, 4HI and 4LO), so you
can select the desired drive mode accord-
ing to the driving conditions.
4WD shift procedure:
Starting and driving5-125

will either remain illuminated or blink.
If the 4WD warning light comes on, the
4WD shift indicator turns off.
High-temperature transfer case oil makes
the 4WD warning light blink rapidly (about
twice per second). If the warning light
blinks rapidly during operation, stop the
vehicle in a safe place immediately. Then
if the light turns off after a while, you can
continue driving.
A large difference between the diameters
of front and rear wheels will make the
4WD warning light blink slowly (about
once per two seconds). Change the 4WD
shift switch to AUTO and do not drive fast.
CAUTION
.If the 4WD warning light comes
on or blinks slowly during opera-
tion or rapidly after stopping the
vehicle for a while, have your
vehicle checked as soon as pos-
sible. It is recommended you visit
a NISSAN dealer for this service.
. Shifting between 4HI and 4LO is
not recommended when the 4WD
warning light turns on.
. When the 4WD warning light
comes on, the 2WD mode may be engaged even if the 4WD shift
switch is in AUTO or 4H. Be
especially careful when driving. If
corresponding parts are malfunc-
tioning, the 4WD mode will not be
engaged even if the 4WD shift
switch is shifted.
. Do not drive the vehicle in the 4HI
or 4LO position on dry hard sur-
face roads. Driving on dry, hard
surfaces in 4HI or 4LO may cause
unnecessary noise, tire wear and
increased fuel consumption.
If the 4WD warning light turns on
when driving on dry hard surface
roads:
— in the AUTO or 4HI position,
shift the 4WD shift switch to
AUTO.
— in the 4LO position, stop the vehicle and shift the transmis-
sion shift lever to the N (Neu-
tral) position and shift the
4WD shift switch to AUTO.
. If the 4WD warning light is still on
after the above operation, have
your vehicle checked as soon as
possible. It is recommended you
visit a NISSAN dealer for this
service. .
The transfer case may be da-
maged if you continue driving
with the warning light blinking.

BRAKING PRECAUTIONS
The brake system has two separate
hydraulic circuits. If one circuit malfunc-
tions, you will still have braking ability at
two wheels.
You may feel a small click and hear a
sound when the brake pedal is fully
depressed slowly. This is not a malfunc-
tion and indicates that the brake assist
mechanism is operating properly.
Hydraulically-assisted brakes
The hydraulically-assisted brake system is
designed to use a hydraulic pump driven
electrically, to assist braking. If the engine
stops, you can stop the vehicle by de-
pressing the foot brake pedal. However,
greater foot pressure on the foot brake
pedal will be required to stop the vehicle.
The stopping distance will be longer.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one
side during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake
pedal to heat-up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakesfunction correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes when-
ever the stopping effect of the parking
brake is weakened or whenever the
parking brake shoes and/or drums/ro-
tors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual. It is recommended you
visit a NISSAN dealer for this service.
Using the brakes
Avoid resting your foot on the brake
pedal while driving. This will cause over-
heating of the brakes, wearing out the
brake and pads faster and reduce gas
mileage.
To help save the brakes and to prevent
the brakes from overheating, reduce
speed and downshift to a lower gear
before going down a slope or long grade.
Overheated brakes may reduce braking
performance and could result in loss of
vehicle control.
WARNING
.
While driving on a slippery sur-
face, be careful when braking,
accelerating or downshifting. Abrupt braking or accelerating
could cause the wheels to skid
and result in an accident.
. If the engine is not running or is
turned off while driving, the
power assist for the brakes will
not work. Braking will be harder.
BRAKE SYSTEM

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

Push the switch on to warn other drivers
when you must stop or park under
emergency conditions. All turn signal
lights will flash.
WARNING
.If stopping for an emergency, be
sure to move the vehicle well off
the road.
. Do not use the hazard warning
flashers while moving on the
highway unless unusual circum-
stances force you to drive so
slowly that your vehicle might
become a hazard to other traffic. .
Turn signals do not work when
the hazard warning flasher lights
are on.
The flasher can be actuated with the
ignition switch in any position.
When an impact that could activate the
supplemental air bags is detected, the
hazard warning flasher lights blink auto-
matically. If the hazard warning flasher
switch is pushed twice, the hazard warn-
ing flashers will turn off.
WARNING
Do not turn the hazard warning
flasher switch to off until you can
make sure that it is safe to do so.
Also, the hazard flasher warning may
not blink automatically depending
on the force of impact.
Some state laws may prohibit the use of
the hazard warning flasher switch while
driving. In the event of a roadside emergency,
Roadside Assistance Service is available
to you. Please refer to your Warranty
Information Booklet (U.S.) or Warranty &
Roadside Assistance Information Booklet
(Canada) for details.
HAZARD WARNING FLASHER SWITCHROADSIDE ASSISTANCE PROGRAM

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.

3. If engine overheating is caused by climbing a long hill on a hot day, run
the engine at a fast idle (approxi-
mately 1,500 rpm) until the tempera-
ture gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from
the radiator before opening the hood.
(If steam or coolant is escaping, turn
off the engine.) Do not open the hood
further until no steam or coolant can
be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent get-
ting burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking or the cooling fan does
not run, stop the engine.
WARNING
Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or get caught in, engine
belts or the engine cooling fan. The
engine cooling fan can start at any
time.
7. After the engine cools down, check the coolant level in the reservoir tank
with the engine running. Add coolant
to the reservoir tank if necessary. Have
your vehicle repaired. It is recom-
mended you visit a NISSAN dealer for
this service.

6-16In case of emergency
When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations
for towing must be followed. Incorrect
towing equipment could damage your
vehicle. Towing instructions are available
from a NISSAN dealer. Local service op-
erators are familiar with the applicable
laws and procedures for towing. To
assure proper towing and to prevent
accidental damage to your vehicle,
NISSAN recommends that you have a
service operator tow your vehicle. It is
advisable to have the service operator
carefully read the following precautions.
WARNING
.Never ride in a vehicle that is
being towed.
. Never get under your vehicle after
it has been lifted by a tow truck.
CAUTION
.When towing, make sure that the
transmission, axles, steering sys-
tem and powertrain are in work-
ing condition. If any of these
conditions apply, dollies or a
flatbed tow truck must be used. .
Always attach safety chains be-
fore towing.

cle behind a recreational vehicle (RV), see
“Flat towing” (P.10-35).
TOWING YOUR VEHICLE

VEHICLE RECOVERY (freeing a stuck
vehicle)
WARNING
.Stand clear of a stuck vehicle.
. Do not spin your tires at high
speed. This could cause them to
explode and result in serious in-
jury. Parts of your vehicle could
also overheat and be damaged.
Pulling a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device
designed specifically for vehicle recovery.
Always follow the manufacturer’s instruc-
tions for the recovery device.
Attach the tow strap to the towing hook.
CAUTION
.Tow chains or cables must be
attached only to the main struc-
tural members of the vehicle or
the towing hooks. Otherwise, the
vehicle body will be damaged.
. Use the towing hook only to free
a vehicle stuck in sand, snow, mud, etc. Never tow the vehicle
for a long distance using only the
towing hook.
. The towing hook is under tre-
mendous force when used to free
a stuck vehicle. Never pull the
hook at an angle.
. Always pull the cable straight out
from the front or rear of the
vehicle.
. Pulling devices should be routed
so they do not touch any part of
the suspension, steering, brake or
cooling systems.
. Pulling devices such as ropes or
canvas straps are not recom-
mended for use in vehicle towing
or recovery.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control
(VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstruc-
tions.
3. Turn the steering wheel right and left to clear an area around the front tires. 4. Slowly rock the vehicle forward and
backward.
.Shift back and forth between R(Reverse) and D (Drive).
.Apply the accelerator as little as possible to maintain the rocking
motion.
.Release the accelerator pedal be-
fore shifting between R and D.
.Do not spin the tires above 35 MPH(55 km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional tow-
ing service to remove the vehicle.
In case of emergency6-19

6-20In case of emergency
This section describes the procedure for
manually shifting the vehicle into the 4WD
mode (4L position) in case of an emer-
gency.
WHEN 4WD WARNING LIGHT ILLU-
MINATES
If the 4WD warning light illuminates while
driving, there may be a malfunction in the
4WD system. Stop the vehicle and have
the vehicle checked as soon as possible. It
is recommended you contact a NISSAN
dealer for this service. (See “NISSAN all-
mode 4WD®” (P.5-124).)
When the vehicle is stuck on an uneven
road (desert, mud, etc.) and the 4WD
warning light is illuminated, be sure to
place the 4WD shift switch in the 4L
position. If only the rear wheels are
spinning, this means that the transfer
has not switched to the 4L position
electrically.
If this situation occurs, contact a dealer or
road assistance service for help. If an
immediate service is not available, per-
form the following procedure to switch to
the 4L position manually and free the
vehicle.
CAUTION
Only perform this procedure in an
emergency.
If the vehicle is driven for a long
period of time over a long distance
with a component detached, foreign
material such as water, sand, etc.
may enter from the opening and this
may cause a malfunction in the
drivetrain system. After freeing a
vehicle that has become stuck, it is
recommended you contact a NISSAN
dealer for inspection and repair.
WARNING
.Ensure your safety before per-
forming the operations. The ve-
hicle may move unexpectedly.
. Place the ignition switch in the
OFF position, apply the parking
brake and let the vehicle cool
down.
. Do not perform the following
procedure immediately after
driving the vehicle. Parts such as
exhaust components, the trans- mission, etc. are very hot and
may cause a burn injury.
. Make sure that the parts that will
be operated as well as related
parts cool down before perform-
ing the operation.
. Burrs or projecting portions of
metal components may cause
unexpected injury to your fingers
or arms. Pay special attention in
regard to your safety while re-
moving and installing these
parts. Wear work gloves and pro-
tective arm covers.
CAUTION
While removing and installing the
parts, prevent the removed parts
from getting dirty with water, dirt or
sand. Protect the parts using a cover
such as a clean cloth, etc.
