2018 NISSAN ALTIMA oil

∙ Your vehicle will reach its ideal oper-ating 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 pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases
tire wear and lowers fuel economy.
∙ Keep the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Recommended fluids/lubricants and
capacities” in the “Technical and con-
sumer information” section of this
manual.
INCREASING FUEL ECONOMY

4. Lower the vehicle slowly until the tiretouches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence illus-
trated (
A,B,C,D,E). Lower the ve-
hicle 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 inter-
val.
Adjust tire pressure to the COLD pres-
sure.
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.
5. Securely store the flat tire and jacking equipment in the vehicle.
6. Place the spare tire cover and the trunk floor carpeting over the damaged tire. NOTE:
You may need to remove the wheel cap
in order to secure the damaged tire us-
ing the spare tire clamp.
7. Close the trunk.
WARNING
∙ Always make sure that the spare tire and jacking equipment are properly
secured af ter use. Such items can be-
come dangerous projectiles in an ac-
cident or sudden stop.
∙ The spare tire is designed for emer- gency use. For additional information,
refer to “Wheels and tires” in the “Do-
it-yourself ” section of this manual.
In case of emergency6-9

∙ Wax your vehicle only af ter a thoroughwashing. Follow the instructions sup-
plied with the wax.
∙ Do not use a wax containing any abra- sives, cutting compounds or cleaners
that may damage the vehicle finish.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint fin-
ish may dull the finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the surface of the paint to avoid last-
ing damage or staining. Special cleaning
products are available at a NISSAN dealer
or any automotive accessory store. It is
recommended that you visit a NISSAN
dealer for these products.
UNDERBODY
In areas where road salt is used in winter, it
is necessary to clean the underbody regu-
larly in order to prevent dirt and salt from
building up and causing the acceleration of
corrosion on the underbody and suspen-
sion. Before the winter period and again in
the spring, the underseal must be checked
and, if necessary, re-treated.
GLASS
When cleaning the rear window, it may be
easier to clean if the inside high-mounted
stop light (if so equipped) is removed first.
Be careful when removing the high-
mounted stop light to reduce the risk of
damaging the high-mounted stop light
wires.
To remove the high-mounted stop light:
1Push toward rear of vehicle.
2Lif t to remove. The high-mounted stop light must be
properly reinstalled before driving your ve-
hicle.
Use glass cleaner to remove smoke and
dust film from the glass surfaces. It is nor-
mal for glass to become coated with a film
af ter the vehicle is parked in the hot sun.
Glass cleaner and a sof t cloth will easily
remove this film.
CAUTION
When cleaning the inside of the win-
dows, do not use sharp-edged tools,
abrasive cleaners or chlorine-based
disinfectant cleaners. They could dam-
age the electrical conductors, radio an-
tenna elements or rear window de-
froster elements.
ALUMINUM ALLOY WHEELS (if so
equipped)
Wash the wheels regularly with a sponge
dampened in a mild soap solution, espe-
cially during winter months in areas where
road salt is used. If not removed, road salt
can discolor the wheels.
WAI0005
Appearance and care7-3

CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
∙ Do not use a cleaner that uses strongacid or alkali contents to clean the
wheels.
∙ Do not apply wheel cleaners to the wheels when they are hot. The wheel
temperature should be the same as
ambient temperature.
∙ Rinse the wheel to completely remove the cleaner within 15 minutes af ter
the cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a
non-abrasive chrome polish to maintain
the finish.
TIRE DRESSINGS
NISSAN does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce discolor-
ation of the rubber. If a tire dressing is ap-
plied to the tires, it may react with the coat-
ing and form a compound. This compound
may come off the tire while driving and
stain the vehicle paint. If you choose to use a tire dressing, take the
following precautions:
∙ Use a water-based tire dressing. The coating on the tire dissolves more easily
than with an oil-based tire dressing.
∙ Apply a light coat of tire dressing to help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove).
∙ Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is
completely removed from the tire
tread/grooves.
∙ Allow the tire dressing to dry as recom- mended by the tire dressing manufac-
turer. Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or sof t bristled brush. Wipe
the vinyl and leather (if so equipped) sur-
faces with a clean, sof t cloth dampened in
mild soap solution, then wipe clean with a
dry, sof t cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather (if so equipped).
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifi-
cation sensor. This can also affect the
operation of the air bag system and re-
sult in serious personal injury.
CLEANING INTERIOR
7-4Appearance and care

CAUTION
∙ Never use benzine, thinner or anysimilar material.
∙ Small dirt particles can be abrasive and damaging to leather surfaces
and should be removed promptly. Do
not use saddle soap, car waxes, pol-
ishes, oils, cleaning fluids, solvents,
detergents or ammonia-based clean-
ers as they may damage the leather’s
natural finish.
∙ Never use fabric protectors unless recommended by the manufacturer.
∙ Do not use glass or plastic cleaner on meter or gauge lens covers. It may
damage the lens cover.
AIR FRESHENERS
Most air fresheners use a solvent that
could affect the vehicle interior. If you use
an air freshener, take the following precau-
tions:
∙ Hanging-type air fresheners can cause permanent discoloration when they
contact vehicle interior surfaces. Place
the air freshener in a location that al-
lows it to hang free and not contact an
interior surface. ∙ Liquid-type air fresheners typically clip
on the vents. These products can cause
immediate damage and discoloration
when spilled on interior surfaces.
Carefully read and follow the manufactur-
er’s instructions before using the air fresh-
eners.
FLOOR MATS (if so equipped)
WARNING
To avoid potential pedal interference
that may result in a collision, injury or
death:
∙ NEVER place a floor mat on top of an- other floor mat in the driver front po-
sition or install them upside down or
backwards.

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, ap-ply 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 key is in the OFF or LOCK position when performing 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 jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even
if the ignition key is in the OFF position
and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before work-
ing 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 neces-
sary to work under the vehicle, sup-
port 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 because
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. Al-
ways conform to local 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 component
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.
