2018 NISSAN ALTIMA sensor

∙ Do not make unauthorized changesto your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
∙ Tampering with the front air bag sys- tem may result in serious personal in-
jury. Tampering includes changes to
the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad and
above the instrument panel or by in-
stalling additional trim material
around the air bag system.
∙ Removing or modif ying the front pas- senger seat may affect the function of
the air bag system and result in seri-
ous personal injury. ∙ Modif ying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing ma-
terial on the seat cushion or by install-
ing additional trim material, such as
seat covers, on the seat that are not
specifically designed to assure proper
air bag operation. Additionally, do not
stow any objects under the front pas-
senger seat or the seat cushion and
seatback. Such objects may interfere
with the proper operation of the occu-
pant classification sensor (weight
sensor).
∙ No unauthorized changes should be made to any components or wiring of
the seat belt system. This may affect
the front air bag system. Tampering
with the seat belt system may result
in serious personal injury. ∙ It is recommended that you visit a
NISSAN dealer for work on and around
the front air bag system. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental Re-
straint System (SRS) wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical
test equipment and probing devices
should not be used on the air bag
system.
∙ A cracked windshield should be re- placed immediately by a qualified re-
pair facility. A cracked windshield
could affect the function of the
supplemental air bag system.
*The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the front air
bag system and guide the buyer to the
appropriate sections in this Owner’s
Manual.

WARNING
∙ Once a front air bag, side air bag, orcurtain air bag has inflated, the air
bag module will not function again
and must be replaced. Additionally,
the activated pretensioner(s) must
also be replaced. The air bag module
and pretensioner(s) should be re-
placed. It is recommended that you
visit a NISSAN dealer for this service.
However, the air bag module and pre-
tensioner(s) cannot be repaired.
∙ The front air bag, side air bag, curtain air bag systems and the pretensioner
system should be inspected if there is
any damage to the front end or side
portion of the vehicle. It is recom-
mended that you visit a NISSAN dealer
for this service.
∙ If you need to dispose of the supple- mental air bag or pretensioner sys-
tems or scrap the vehicle, it is recom-
mended that you visit a NISSAN
dealer. Incorrect disposal procedures
could cause personal injury. ∙ If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) should be
checked to verif y it is still functioning
correctly. It is recommended that you
visit a NISSAN dealer for this service.
The OCS should be checked even if no
air bags deploy as a result of the im-
pact. Failure to verif y proper OCS
function may result in an improper air
bag deployment resulting in injury or
death.

2-30Instruments and controls

Be sure you do not put anything on top of
the autolight sensor located in the top side
of the instrument panel. The autolight sen-
sor controls the autolight; if it is covered,
the autolight sensor reacts as if it is dark
out and the headlights will illuminate. If this
occurs while parked with the engine off
and the key in the ON position, your vehi-
cle’s battery could become discharged.Headlight beam select
1To select the high beam function, en-
sure the low beams are engaged, and
push the lever forward. The high beam
lights come on and the blue
indi-
cator light illuminates.
2Pull the lever back to return to the low
beam.
3Pulling and releasing the lever flashes
the headlight high beams on and off.
The low beams need not be engaged
for this function.
Battery saver system
If the ignition switch is placed in the OFF
position while the headlight switch is in
the
orposition, the headlights
will turn off af ter a period of time.
NOTE:
The Battery Saver system may be dis-
abled. For additional information, refer
to “Vehicle information display ” in this
section.
CAUTION
Even though the battery saver feature
automatically turns off the headlights
af ter a period of time, you should turn
the headlight switch to the OFF position
when the engine is not running to avoid
discharging the vehicle battery.

To access the vanity mirror, pull the sun
visor down and flip open the mirror cover.
Some vanity mirrors are illuminated and
turn on when the mirror cover is open.
MANUAL ANTI-GLARE REARVIEW
MIRROR (if so equipped)
Use the night position1to reduce glare
from the headlights of vehicles behind you
at night.
Use the day position
2when driving in
daylight hours.
WARNING
Use the night position only when neces-
sary, because it reduces rear view
clarity.
AUTOMATIC ANTI-GLARE
REARVIEW MIRROR (if so equipped)
The inside mirror is designed so that it au-
tomatically dims during night time condi-
tions and according to the intensity of the
headlights of the vehicle following you. The
automatic anti-glare feature is activated
when the ignition switch is in the ON posi-
tion.
The indicator light
2will illuminate when
the automatic anti-glare feature is operat-
ing.
NOTE:
Do not hang any objects over the sen-
sors
1or apply glass cleaner to the sen-
sors. Doing so will reduce the sensitivity
of the sensors, resulting in improper op-
eration.

OPERATING TIPS
The sunload sensor, located on the top
driver’s side of the instrument panel, helps
the system maintain a constant tempera-
ture. Do not put anything on or around this
sensor.∙ When the climate system is in auto-
matic operation and the engine coolant
temperature and outside air tempera-
ture are low, the air flow outlet may de-
fault to defroster mode for a maximum
of 2 minutes 30 seconds. This is not a
malfunction. Af ter the engine coolant
temperature warms up, the air flow out-
let will return to foot mode and opera-
tion will continue normally.
∙ When the outside and interior cabin temperatures are moderate to high, the
intake setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may oc-
cur when previous climate setting was
system off. This is not a malfunction.
Af ter the initial warm air is expelled, the
intake will return to automatic control,
air flow outlet will return to previous set-
tings, and operation will continue nor-
mally. To exit, press any climate control
button.
∙ Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration.
