2021 NISSAN ARMADA differential

8-38Do-it-yourself
the same size and you are only
replacing 2 of the 4 tires, install
the new tires on the rear axle.
Placing new tires on the front
axle may cause loss of vehicle
control in some driving condi-
tions and cause an accident and
personal injury.
. If the wheels are changed for any
reason, always replace with
wheels which have the same off-
set dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics and/or
interference with the brake
discs/drums. Such interference
can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. See “Wheels and
tires” (P.10-9) for wheel off-set
dimensions.
. 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.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. It is recommended you
visit a NISSAN dealer for ID regis-
tration.
. 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
deformed 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 tire is not
recommended.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
Four-Wheel Drive (4WD) 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 circum-
ference difference between tires
on the front and rear axles which
will cause excessive tire wear and
may damage the transmission,
transfer case and differential
gears.
. ONLY use spare tires specified for
the 4WD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,

construction and tread pattern. The tire
pressure and wheel alignment should
also be checked and corrected as neces-
sary. It is recommended 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.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehi-
cle could lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information”
(Canada) in the NISSAN Warranty Infor-
mation Booklet.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Spare tire
Since the spare tire is not equipped with
the TPMS, when a spare tire is mounted
(TEMPORARY USE ONLY or conventional),
the TPMS will not function.
Spare tire (FULL-SIZE TEMPORARY USE
ONLY spare tire) (Applies ONLY to vehi-
cles equipped with P275/50R22 or
P275/60R20 tires):
Observe the following precautions if the
full-size temporary use only spare tire
must be used, otherwise your vehicle
could be damaged or involved in an
accident.
WARNING
.The full-size temporary use only
spare tire should be used for
emergency use. It should be re-
placed with the standard tire at
the first opportunity to avoid
possible tire or differential da-
mage.
. Drive carefully while the spare tire
is installed. Avoid sharp turns and
abrupt braking while driving. The
vehicle driving performance may
be affected when driving on wet
or snow covered roads. .
When the spare tire is installed,
the following systems may not
work correctly.
— Tire Pressure Monitoring Sys-
tem (TPMS)
— Vehicle Dynamic Control (VDC) System
. Periodically check spare tire in-
flation pressure. Always keep the
spare tire inflated to the pressure
specification shown on the Tire
and Loading Information label.
For Tire and Loading Information
label location, see “Tire and Load-
ing Information label” in the index
of this manual.
. With the spare tire installed do
not drive your vehicle at speeds
faster than 70 MPH (112 km/h).
. When driving on roads covered
with snow or ice, the spare tire
should be used on the front
wheels and original tire used on
the rear wheels (drive wheels).
Use tire chains only on the two
rear original tires.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare
tire at the same time.

9-6Maintenance and schedules
Engine oil and oil filter:
Replace engine oil and oil filter at the
specified intervals. For recommended oil
grade and viscosity refer to “Capacities
and recommended fluids/lubricants”
(P.10-2).
Engine valve clearance*:
Inspect only if valve noise increases.
Adjust valve clearance if necessary.
Evaporative Emissions Control Vapor
Lines*:
Check vapor lines for leaks or looseness.
Tighten connections or replace parts as
necessary.
Fuel filter:
Periodic maintenance is not required. (in-
tank type filter)
