2018 NISSAN ALTIMA warning light

If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-
adjust every time the brake pedal is ap-
plied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended that you
visit a NISSAN dealer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched
scraping or screeching sound will be heard
when the vehicle is in motion. The noise will
be heard whether or not the brake pedal is
depressed. Have the brakes checked as
soon as possible if the wear indicator
sound is heard.Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information re-
garding brake inspections, refer to the ap-
propriate maintenance schedule informa-
tion in the "Maintenance and schedules"
section of this manual.
If any electrical equipment does not oper-
ate, check for an open fuse.
Fuses are used in the passenger and en-
gine compartment. Spare fuses are pro-
vided and can be found in the passenger
compartment fuse box.
When installing a fuse make sure the fuse is
installed in the fuse box securely.

If you have a flat tire, refer to “Flat tire” in
the “In case of emergency ” section of
this manual.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely af-
fect electric medical equipment.
Those who use a pacemaker
should contact the electric medi-
cal equipment manufacturer for
the possible influences before
use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all tires
except the spare. When the low tire
pressure warning light is lit and the
“Tire Pressure Low - Add Air” warning
appears in the vehicle information
display, one or more of your tires is
significantly under-inflated.
The TPMS will activate only when the
vehicle is driven at speeds above 16 mph (25 km/h). Also, this system
may not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
For additional information, refer to
“Low tire pressure warning light” in the
“Instruments and controls” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving”
section, and “Flat tire” in the “In case of
emergency” section of this manual.
Tire inflation pressure
Check the tire pressures (including
the spare) of ten and always prior to
long distance trips. The recom-
mended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S.
certification label or the Tire and
Loading Information label under the
"Cold Tire Pressure" heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
∙ Most tires naturally lose air over
time.
∙ Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a
curb while parking.
The tire pressures should be
checked when the tires are cold. The
tires are considered COLD af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
The TPMS with Easy-Fill Tire Alert
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
refer to “TPMS with Easy-Fill Tire
Alert” in the “Starting and driving”
section of this manual.
If the tires are used at speeds above
100 mph (162 km/h) where it is legal
to do so (on a race track for ex-
ample), the cold tire inflation pres-
sure must be increased. For addi-
WHEELS AND TIRES
Do-it-yourself8-31

Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. For ad-
ditional information, refer to “Wheels and
tires” in the “Technical and consumer infor-
mation” section of this manual.
WARNING
∙ The use of tires other than those rec-ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, Vehicle Dynamic
Control (VDC) system, ground clear-
ance, body-to-tire clearance, tire
chain clearance, speedometer cali-
bration, headlight aim and bumper
height. Some of these effects may
lead to accidents and could result in
serious personal injury. ∙ If your vehicle was originally
equipped with four tires that were the
same size and you are only replacing
two of the four 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 per-
sonal injury
∙ If the wheels are changed for any rea- son, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information
on wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section of
this manual. ∙ When replacing a wheel without the
TPMS, such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for this service.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ The TPMS sensor may be damaged if it is not handled correctly. Be careful
when handling the TPMS sensor.
∙ When replacing the TPMS sensor, the ID registration may be required. It is
recommended that you visit a NISSAN
dealer for ID registration.
∙ 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.

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* (for serviceable batteries):
Check the fluid level in each cell. The fluid
should be at the bottom of the filler open-
ing. Vehicles operated in high tempera-
tures or under severe conditions 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 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. 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 the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
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, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, refer to “Exhaust gas (carbon mon-
oxide)” in the “Starting and driving” section
of this manual.
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
