2021 NISSAN ARMADA ECU

9-4Maintenance and schedules
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Steering wheel:Check for changes in the
steering conditions, such as excessive
free play, hard steering or strange noises.
Warning lights and chimes: Make sure
that all warning lights and chimes are
operating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets prop-
erly and in sufficient quantity when oper-
ating the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate
properly and that the wipers do not
streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example,
each time you check the engine oil or
refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level. NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start condi-
tions such as:
1.
Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
2. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the
oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in- spected. It is recommended you visit a
NISSAN dealer for this service. (See “Pre-
cautions when starting and driving” (P.5-
4) for exhaust gas (carbon monoxide).)
Fluid leaks:
Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks
or if gasoline fumes are evident, check for
the cause and have it corrected immedi-
ately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control
dust. It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt
may accumulate. For additional informa-

SECURING THE LOAD
There are tie down hooks located in the
cargo area as shown. The tie down hooks
can be used to secure cargo with ropes or
other types of straps.
Do not apply a total load of more than
22 lb (10 kg) to a single hook
or 7 lb (3
kg) to a single hookwhen securing
cargo.
WARNING
. Properly secure all cargo with
ropes or straps to help prevent it
from sliding or shifting. Do not place cargo higher than the seat-
backs. In a sudden stop or colli-
sion, unsecured cargo could
cause personal injury.
. The child restraint top tether
strap may be damaged by con-
tact with items in the cargo area.
Secure any items in the cargo
area. Your child could be seriously
injured or killed in a collision if the
top tether strap is damaged.
. Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear GAWRs.
If you do, parts of your vehicle
can break, tire damage could
occur, or it can change the way
your vehicle handles. This could
result in loss of control and cause
personal injury.
LOADING TIPS
.The GVW must not exceed GVWR
or GAWR as specified on the F.M.
V.S.S./C.M.V.S.S. certification la-
bel.
.Do not load the front and rear
axle to the GAWR. Doing so will
exceed the GVWR.
WARNING
.Properly secure all cargo to
help prevent it from sliding
or shifting. Do not place
cargo higher than the seat-
backs. In a sudden stop or
collision, unsecured cargo
could cause personal injury.
. Do not load your vehicle any
heavier than the GVWR or
the maximum front and rear
GAWRs. If you do, parts of
your vehicle can break, tire
damage could occur, or it
can change the way your
vehicle handles. This could
result in loss of control and
cause personal injury.
. Overloading not only can
shorten the life of your ve-
hicle and the tire, but can
cause unsafe vehicle hand-
ling and long braking dis-
tance. This may cause a
premature tire failure, which
could result in a serious

accident and personal in-
jury. Failures caused by
overloading are not covered
by the vehicle’s warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shifts that could affect the
balance of your vehicle. When the
vehicle is loaded, drive to a scale
and weigh the front and the rear
wheels separately to determine
axle loads. Individual axle loads
should not exceed either of the
gross axle weight ratings (GAWR).
The total of the axle loads should
not exceed the gross vehicle
weight rating (GVWR). These ratings
are given on the vehicle certifica-
tion label. If weight ratings are
exceeded, move or remove items
to bring all weights below the
ratings.WARNING
Overloading or improper loading of a
trailer and its cargo can adversely
affect vehicle handling, braking and
performance and may lead to acci-
dents.
CAUTION
. Do not tow a trailer or haul a
heavy load for the first 500 miles
(800 km). Your engine, axle or
other parts could be damaged.
. For the first 500 miles (800 km)
that you tow a trailer, do not drive
over 50 MPH (80 km/h) and do
not make starts at full throttle.
This helps the engine and other
parts of your vehicle wear in at
the heavier loads.
Your new vehicle was designed to be
used primarily to carry passengers and
cargo. Remember that towing a trailer
places additional loads on your vehicle’s
engine, drivetrain, steering, braking and
other systems.
A NISSAN Towing Guide (U.S. only) is available on the website at
www.nissanusa.com. This guide includes
information on trailer towing capability
and the special equipment required for
proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to
exceed the value specified in the “Towing
load/specification” (P.10-23). The total
trailer load equals trailer weight plus its
cargo weight.
.
When towing a trailer load of 3,500
lbs (1,587 kg) or more, trailers with a
brake system MUST be used.
The maximum Gross Combined Weight
Rating (GCWR) should not exceed the
value specified in the following “Towing
Load/Specification” chart.
Technical and consumer information10-19
TOWING A TRAILER

WAJ0219X
To install the trailer hitch cover:
1. Insert the upper clips to the recesses
, and then push in the cover to its
original position.
2. Install the 2 clips
.
WARNING
Trailer hitch components have spe-
cific weight ratings. Your vehicle may
be capable of towing a trailer heavier
than the weight rating of the hitch
components. Never exceed the
weight rating of the hitch compo-
nents. Doing so can cause serious personal injury or property damage.
Hitch ball
Choose a hitch ball of the proper size and
weight rating for your trailer:
.
The required hitch ball size is stamped
on most trailer couplers. Most hitch
balls also have the size printed on top
of the ball.
. Choose the proper class hitch ball
based on the trailer weight.
. The diameter of the threaded shank of
the hitch ball must be matched to the
ball mount hole diameter. The hitch
ball shank should be no more than
1/16″ smaller than the hole in the ball
mount.
. The threaded shank of the hitch ball
must be long enough to be properly
secured to the ball mount. There
should be at least 2 threads showing
beyond the lock washer and nut.
Ball mount
The hitch ball is attached to the ball
mount and the ball mount is inserted into
the hitch receiver. Choose a proper class
ball mount based on the trailer weight.
Additionally, the ball mount should be
chosen to keep the trailer tongue level
with the ground.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and
gross weight directly on the ball mount
and on the receiver.
Weight distribution hitch
This type of hitch is also called a “load-
leveling” or “equalizing” hitch. A set of bars
attach to the ball mount and to the trailer
to distribute the tongue weight (hitch
weight) of your trailer. Many vehicles
cannot carry the full tongue weight of a
given trailer, and need some of the
tongue weight transferred through the
frame and pushing down on the front
wheels. This gives stability to the tow
vehicle.
A weight-distributing hitch system (Class
IV) is recommended if you plan to tow
trailers with a maximum weight over
5,000 lbs (2,267 kg). Check with the trailer
and towing equipment manufacturers to
determine if they recommend the use of a
weight-distributing hitch system.
NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge
brakes. If you are considering use of a
weight-distributing hitch system with a
surge brake-equipped trailer, check
Technical and consumer information10-25

10-32Technical and consumer information
Pre-towing tips
.Be certain your vehicle maintains a
level position when a loaded or un-
loaded trailer is hitched. Do not drive
the vehicle if it has an abnormal nose-
up or nose-down condition; check for
improper tongue load, overload, worn
suspension or other possible causes
of either condition.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible
in the trailer to keep the trailer center
of gravity low.
. Load the trailer so approximately 60%
of the trailer load is in the front half
and 40% is in the back half. Also make
sure the load is balanced side to side.
. Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light op-
eration, and trailer wheel lug nuts
every time you attach a trailer to the
vehicle.
. Be certain your rearview mirrors con-
form to all federal, state or local
regulations. If not, install any mirrors
required for towing before driving the
vehicle.
. Determine the overall height of the
vehicle and trailer so the required
clearance is known.
Trailer towing tips
In order to gain skill and an understand-
ing of the vehicle’s behavior, you should
practice turning, stopping and backing up
in an area which is free from traffic.
Steering stability, and braking perfor-
mance will be somewhat different than
under normal driving conditions.
.Always secure items in the trailer to
prevent load shift while driving.
. Lock the trailer hitch coupler with a
pin or lock to prevent the coupler from
inadvertently becoming unlatched.
. Avoid abrupt starts, acceleration or
stops.
. Avoid sharp turns or lane changes.
. Always drive your vehicle at a moder-
ate speed. Some states or provinces
have specific speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
. When backing up, hold the bottom of
the steering wheel with one hand.
Move your hand in the direction in
which you want the trailer to go. Make
small corrections and back up slowly.
If possible, have someone guide you
when you are backing up.
Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you must do so:
CAUTION
If you move the shift lever to the P
(Park) position before blocking the
wheels and applying the parking
brake, transmission damage could
occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer
wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until
the blocks absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park).
6. Four-Wheel Drive (4WD) models:
Make sure that the 4WD shift switch is
engaged in the AUTO, 4HI or 4LO
position and the Automatic Transmis-
sion (AT) park warning light is turned
off.
7. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal.

WARNING
A vehicle equipped with Four-Wheel
Drive (4WD) should never be tested
using a two wheel dynamometer
(such as the dynamometers used by
some states for emissions testing),
or similar equipment. Make sure you
inform test facility personnel that
your vehicle is equipped with 4WD
before it is placed on a dynam-
ometer. Using the wrong test equip-
ment may result in transmission
damage or unexpected vehicle
movement which could result in
serious vehicle damage or personal
injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” for an Inspection/Main-
tenance (I/M) test of the emission control
system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of
the vehicle.
If a powertrain system component is
repaired or the battery is disconnected,
