2018 NISSAN ALTIMA SL warning light

This light illuminates when the AEB with
Pedestrian Detection system is set to OFF
in the vehicle information display.
If the light illuminates when the AEB with
Pedestrian Detection system is on, it may
indicate that the system is unavailable. For
additional information, refer to “Automatic
Emergency Braking (AEB) with Pedestrian
Detection” and “Intelligent Forward Colli-
sion Warning (I-FCW)” in the “Starting and
driving” section of this manual.

Electronic parking brakewarning light (yellow)
(if so equipped)
The electronic parking brake system
warning light functions for the electronic
parking brake system. If the warning light
illuminates, it may indicate the electronic
parking brake system is not functioning
properly. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
For additional information, refer to “Parking
brake” in the “Starting and driving” section
of this manual.

TPMS malfunction
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The light
will remain on af ter 1 minute. Have the sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service. The "Tire
Pressure Low — Add Air" warning does not
appear if the low tire pressure warning light
illuminates to indicate a TPMS malfunction.
For additional information, refer to “Tire
Pressure Monitoring System (TPMS)” in the
“Starting and driving” section and “Tire
pressure” in the “Do-it-yourself ” section of
this manual.

Master warning light
When the ignition is in the ON position, the
master warning light illuminates if any of
the following are displayed on the vehicle
information display.∙ No key warning
∙ Low windshield-washer fluid warning
∙ Parking brake release warning
∙ Door/trunk open warning
∙ Loose fuel cap
∙ Low tire pressure warning

Supplemental air bagwarning light
When the ignition switch is placed in the ON
or START position, the supplemental air
bag warning light illuminates for about
7 seconds and then turns off. This means
the system is operational.
If any of the following conditions occur, the
front air bag, side air bag, curtain air bag,
and pretensioner systems need servicing
and your vehicle must be taken to a NISSAN
dealer:
∙ The supplemental air bag warning light remains on af ter approximately 7 sec-
onds.
∙ The supplemental air bag warning light flashes intermittently.
∙ The supplemental air bag warning light does not come on at all.
Unless checked and repaired, the supple-
mental restraint system (air bag system)
and/or the pretensioners may not function
properly. For additional details, refer to
“Supplemental Restraint System (SRS)” in
the “Safety—Seats, seat belts and supple-
mental restraint system” section of this
manual.

Locking doors
1. Move the shif t lever to the P (Park) posi-tion, place the ignition switch in the
LOCK position and make sure you carry
the Intelligent Key with you.
2. Close all doors.
3. Push any door handle request switch
1while carrying the Intelligent Key
with you.
4. All doors and the trunk will lock.
5. The hazard warning lights flash twice and the outside chime sounds twice. NOTE:
∙ Request switches for all doors and trunk can be deactivated when the “Ext.
Door Switch” setting is switched to OFF
in the vehicle settings of the vehicle in-
formation display. For additional infor-
mation, refer to “Vehicle information
display” in the “Instruments and con-
trols” section of this manual.
∙ Doors lock with the door handle re- quest switch while the ignition switch is
not in the LOCK position. ∙ Doors do not lock by pushing the door
handle request switch while any door is
open. However, doors lock with the me-
chanical key even if any door is open.
∙ Doors do not lock with the door handle request switch with the Intelligent Key
inside the vehicle and a beep sounds to
warn you. However, when an Intelligent
Key is inside the vehicle, doors can be
locked with another Intelligent Key.

Additional information:∙ When replacing a wheel without the TPMS such as the spare tire, the TPMS
does not monitor the tire pressure of
the spare tire.
∙ 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 pres-
sure (for example, a flat tire while driv-
ing).
∙ The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted on all four tires. Af-
ter all four tires are inflated to the rec-
ommended pressure, the vehicle must
be driven at speeds above 16 mph
(25 km/h) to activate the TPMS and turn
off the low tire pressure warning light.
Use a tire pressure gauge to check the
tire pressure.
∙ The “Tire Pressure Low - Add Air” warn- ing appears in the vehicle information
display when the low tire pressure
warning light is illuminated and low tire
pressure is detected. The “Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light turns
off. ∙ The “Tire Pressure Low - Add Air” warn-
ing appears each time the ignition
switch is placed in the ON position as
long as the low tire pressure warning
light remains illuminated.
∙ The “Tire Pressure Low - Add Air” warn- ing does not appear if the low tire pres-
sure warning light illuminates to indi-
cate a TPMS malfunction.
∙ Tire pressure rises and falls depending on the heat caused by the vehicle’s op-
eration and the outside temperature.
Do not reduce the tire pressure af ter
driving because the tire pressure rises
af ter driving. Low outside temperature
can lower the temperature of the air
inside the tire which can cause a lower
tire inflation pressure. This may cause
the low tire pressure warning light to
illuminate. If the warning light illumi-
nates, check the tire pressure for all four
tires.
∙ The Tire and Loading Information label is located in the driver’s door opening. ∙ You can also check the tire pressure of
all tires (except the spare) on the vehicle
information display screen. The order of
the tire pressure figures displayed on
the screen corresponds with the actual
order of the tire position.
For additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “In case of
emergency” section and “Tire pressure” in
the “Do-it-yourself ” section of this manual.

∙ If the low tire pressure warning lightilluminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop
the vehicle as soon as possible. Driv-
ing with underinflated tires may per-
manently damage the tires and in-
crease the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light off. If you have a flat
tire, replace it with a spare tire as soon
as possible. (For additional informa-
tion, refer to “Flat tire” in the “In case of
emergency ” section for changing a
flat tire.) ∙ When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, tire pressure will not be indi-
cated, the TPMS will not function and
the low tire pressure warning light will
flash for approximately 1 minute. The
light will remain on af ter 1 minute. It is
recommended that you visit a NISSAN
dealer for tire replacement and/or
system resetting.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
