2023 NISSAN ALTIMA low oil pressure

7.Avoid Idling
• Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
• Automated passes permit drivers to use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting.
9. Winter Warm Up
• Limit idling time to minimize impact to fuel economy.
• Vehicles typically need no more than 30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving.
• Your vehicle will reach its ideal operat- ing temperature more quickly while
driving versus idling.
10. Keeping your Vehicle Cool
• Park your vehicle in a covered parking area or in the shade whenever
possible.
• When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, see “Engine
oil and oil filter recommendations”
(P. 10-7).
If any malfunction occurs in the AWD sys-
tem while the engine is running, messages
are displayed in the meter.
If the AWD error warning message is dis-
played, there may be a malfunction in the
AWD system. Reduce vehicle speed and
have your vehicle checked. It is recom-
mended that you visit a NISSAN dealer as
soon as possible.

equipped)

Installing the spare tire
WARNING
For AWD vehicles - the TEMPORARY USE
ONLY spare tire must be installed to the
rear wheels only. If a front tire is punc-
tured, install the original rear tire onto
the front wheel, then install the TEMPO-
RARY USE ONLY spare tire on the rear.
Failure to do so could cause overheat-
ing to the AWD system
The spare tire is designed for emergency
use. For additional information, see
“Wheels and tires” (P. 8-29). 1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence illustrated (
OA,OB,OC,OD,OE)
until they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence illustrated
(
OA,OB,OC,OD,OE). Lower the vehicle
completely.
WARNING
• Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
• Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
• Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.). As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque:
83 f t-lb (113 N·m)
The wheel nuts must be kept tightened
to specification at all times. It is recom-
mended that wheel nuts be tightened to
specifications at each lubrication
interval.
Adjust tire pressure to the COLD
pressure.
COLD pressure: Af ter vehicle has been
parked for 3 hours or more or driven less
than 1 mile (1.6 km).
COLD tire pressures are shown on the
Tire Load and Information label affixed
to the driver side center pillar.
Af ter adjusting tire pressure to the COLD
tire pressure, the display (if so equipped)
of the tire pressure information may
show higher pressure than the COLD tire
pressure af ter the vehicle has been
driven more than 1 mile (1.6 km). This is
because the tire pressure increases as
the tire temperature rises. This does not
indicate a system malfunction.

6-10In case of emergency

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
• Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
• It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle. •
Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without
warning, even if the ignition switch is
in the OFF position and the engine is
not running. To avoid injury, always
disconnect the negative battery
cable before working near the fan.
• If you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
• Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• On gasoline engine models, the fuel
filter or fuel lines should be serviced.
It is recommended that you visit a
NISSAN dealer for this service be-
cause the fuel lines are under high
pressure even when the engine is off.
CAUTION
• Do not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down. •
Avoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
• Never leave the engine or the trans-
mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, see
“Owner's Manual/Service Manual order in-
formation” (P. 10-26).
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.
