2019 NISSAN ALTIMA check engine light

During the normal day-to-day operation of
the vehicle, general maintenance should
be performed regularly as prescribed in
this section. If you detect any unusual
sounds, vibrations or smells, be sure to
check for the cause or have it checked
promptly. In addition, it is recommended
that you visit a NISSAN dealer if you think
that repairs are required.
When performing any checks or mainte-
nance work, closely observe the “Mainte-
nance precautions” in the “Do-it-yourself ”
section of this manual.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with“*”isfound in the “Do-it-
yourself ” section of this manual.
Outside the vehicle
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Doors and engine hood:
Check that the
doors and engine hood operate properly.
Also ensure that all latches lock securely. Lu-
bricate hinges, latches, latch pins, rollers and
links if necessary. Make sure that the sec- ondary latch keeps the hood from opening
when the primary latch is released.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Lights*:
Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: PR25DD Engine model; Tires
should be rotated every 5,000 miles
(8,000 km).
KR25DDET Engine Model; Tires should be
rotated every 7,500 miles (12,000 km).
Tires*: Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace theTPMS transmitter grommet seal, valve core
and cap when the tires are replaced due to
wear or age.
Wheel alignment and balance:
If the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may
be a need for wheel alignment. If the steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield: Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind-
shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to
http://collision.nissanusa.com.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
GENERAL MAINTENANCE
Maintenance and schedules9-3

Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc.
Accelerator pedal:Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Continuously Variable Transmission
(CVT) P (Park) position mechanism: On a
fairly steep hill check that the vehicle is held
securely with the shif t lever in the P (Park)
position without applying any brakes.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
Seats:
Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters 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 system, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner. Windshield wiper and washer*:
Check
that the wipers and washer operate prop-
erly 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*: This vehicle is equipped with a
sealed maintenance free battery. It is rec-
ommended that you visit a NISSAN dealer
for service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery 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.
9-4Maintenance and schedules

Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can
cause persistent, heavy “spark knock.”
(“Spark knock” is a metallic rapping
noise.) If severe, this can lead to engine
damage. If you detect a persistent heavy
spark knock even when using gasoline
of the stated octane rating, or if you hear
steady spark knock while holding a
steady speed on level roads, it is recom-
mended that you have a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not
a cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure
satisfactory engine life and performance.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in this section. NISSAN recommends the
use of an energy conserving oil in order to
improve fuel economy.
Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification orInternational Lubricant Standardization and
Approval Committee (ILSAC) certification
and SAE viscosity standard. These oils have
the API certification mark on the front of the
container. Oils which do not have the speci-
fied quality label should not be used as they
could cause engine damage.
Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
LTI2303
10-6Technical and consumer information

WARNING
A vehicle equipped with All -Wheel Drive
(AWD) should never be tested using a
two wheel dynamometer (such as the
dynamometers used by some states for
emissions testing), or similar equip-
ment. Make sure you inform the test fa-
cility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle 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/
Maintenance (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 ve-
hicle. If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready” condi-
tion. Before taking the I/M test, check the
vehicle’s inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds , the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
This vehicle is equipped with an EDR. The
main purpose of an EDR is to record, in
certain collision or near collision-like situa-
tions, such as an air bag deployment or
hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems
performed. The EDR is designed to record
data related to vehicle dynamics and
safety systems for a short period of time,
typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
∙ How various systems in your vehicle were operating;
∙ Whether or not the driver and passen- ger safety belts were buckled/fastened;
∙ How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
∙ How fast the vehicle was traveling.
∙ Sounds are not recorded.
