2019 NISSAN ALTIMA SL ignition

∙ Be sure the seat belt tongue is se-curely fastened to the proper buckle.
∙ Do not wear the seat belt inside out or twisted. Doing so may reduce its
effectiveness.
∙ Do not allow more than one person to use the same seat belt.
∙ Never carry more people in the vehicle than there are seat belts.
∙ If the seat belt warning light glows continuously while the ignition is
turned ON with all doors closed and all
seat belts fastened, it may indicate a
malfunction in the system. Have the
system checked. It is recommended
that you visit a NISSAN dealer for this
service.
∙ No changes should be made to the seat belt system. For example, do not
modif y the seat belt, add material, or
install devices that may change the
seat belt routing or tension. Doing so
may affect the operation of the seat
belt system. Modif ying or tampering
with the seat belt system may result
in serious personal injury. ∙ Once seat belt pretensioner(s) have
activated, they cannot be reused and
must be replaced together with the
retractor. It is recommended that you
visit a NISSAN dealer for this service.
∙ All seat belt assemblies, including retractors and attaching hardware,
should be inspected af ter any colli-
sion. It is recommended that you visit
a NISSAN dealer for this service.
NISSAN recommends that all seat belt
assemblies in use during a collision be
replaced unless the collision was mi-
nor and the belts show no damage
and continue to operate properly.
Seat belt assemblies not in use during
a collision should also be inspected
and replaced if either damage or im-
proper operation is noted.
∙ All child restraints and attaching hardware should be inspected af ter
any collision. Always follow the re-
straint manufacturer’s inspection
instructions and replacement recom-
mendations. The child restraints
should be replaced if they are
damaged.
SEAT BELT WARNING LIGHT AND
CHIME
The driver and front passenger seat is
equipped with an enhanced seat belt re-
minder function. If your vehicle is equipped
with an enhanced seat belt reminder func-
tion, a visual and audible alert will operate if
a driver or front passenger seat belt is un-
buckled at speeds of approximately 9 mph
(15 km/h) or more under the following con-
ditions:
∙ If the driver seat belt is not fastened.

∙ The front passenger’s seat belt is notfastened and the seat is occupied by a
passenger for 7 seconds af ter the igni-
tion switch is placed in the ON position.
∙ The front passenger’s seat belt is not fastened and objects or external force
on the passenger seat change the seat
belt reminder classification to Occu-
pied.
The seat belt warning light will flash under
the conditions shown above until the nec-
essary seat belt is securely fastened.
A warning chime will sound for approxi-
mately 90 seconds or until one of the fol-
lowing conditions is met: ∙ The unbuckled front occupant’s seat belt is securely fastened.
∙ The seat belt reminder function in the front passenger seat no longer detects
that the front passenger seat is occu-
pied.
∙ The ignition is turned off. The below situations could result in the
seat belt reminder light being illuminated
and the chime sounding, even with no oc-
cupant present in the passenger seat:
∙ Heavy objects placed on the seat.
∙ Someone pushing or pulling on the front passenger seat.
∙ An object placed under the front pas- senger seat.
∙ An object placed between the seat cushion and center console or between
the seat cushion and the door.
∙ An object hanging on the seat or placed in the seatback pocket.
∙ A child restraint or other object pressing against the rear of the seatback.
PREGNANT WOMEN
NISSAN recommends that pregnant
women use seat belts. The seat belt should
be worn snug and always position the lap
belt as low as possible around the hips, not
the waist. Place the shoulder belt over your
shoulder and across your chest. Never run
the lap/shoulder belt over your abdominal
area. Contact your doctor for specific rec-
ommendations.
INJURED PERSONS
NISSAN recommends that injured persons
use seat belts. Check with your doctor for
specific recommendations.
THREE-POINT TYPE SEAT BELT
WITH RETRACTOR

Driver and passenger supplemental knee
air bags
This system can help cushion the impact
force to the driver’s and front passenger’s
knees in certain collisions.
The SRS is designed tosupplementthe
crash protection provided by the driver and
front passenger and rear seat belts and is
not a substitute for them. Seat belts
should always be correctly worn and the
occupant seated a suitable distance away
from the steering wheel, instrument panel
and door finishers. For additional informa-
tion, refer to “Seat belts” in this section.
The supplemental air bags operate only
when the ignition switch is placed in the
ON position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.

although they may inflate if the forces in
another type of collision are similar to
those of a higher severity impact. They are
designed to inflate on the side where the
vehicle is impacted. They may not inflate in
certain side collisions.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (for example, during severe off-
roading) may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always
an indication of proper side air bag and
curtain air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by the release of smoke. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on
the chest and pelvic area of the front and
rear outboard occupants. Curtain air bags
help to cushion the impact force to the
head of occupants in the front and rearoutboard seating positions. They can help
save lives and reduce serious injuries. How-
ever, an inflating side air bag and curtain air
bag may cause abrasions or other injuries.
Side air bags and curtain air bags do not
provide restraint to the lower body.
The seat belts should be correctly worn
and the driver, front passenger and rear
outboard occupants seated upright as far
as practical away from the side air bag.
Rear seat passengers should be seated as
far away as practical from the door finish-
ers and side roof rails. The side air bags and
curtain air bags inflate quickly in order to
help protect the occupants. Because of
this, the force of the side air bag and curtain
air bag inflating can increase the risk of
injury if the occupant is too close to, or is
against, these air bag modules during in-
flation. The side air bag will deflate quickly
af ter the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags
operate only when the ignition switch is
placed in the ON position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.

Vehicle damage (or lack of it) is not always
an indication of proper knee air bag opera-
tion.
When the knee air bag inflates, a fairly loud
noise may be heard, followed by release of
smoke. This smoke is not harmful and
does not indicate a fire. Care should be
taken not to inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.The knee air bag helps to cushion the im-
pact force on the knees of the driver and
passenger. It can help reduce serious inju-
ries. However, an inflating knee air bag may
cause abrasions or other injuries. The knee
air bag provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of
this, the force of the knee air bag inflating
can increase the risk of injury if the occu-
pant is too close to, or is against, this air bag
module during inflation. The knee air bag
will deflate quickly af ter the collision is over
OR the knee air bag will remain inflated for
a short time.
The knee air bag operates only when the
ignition switch is placed in the ON posi-
tion.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.

FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle returns to 0 (Empty) af-
ter the ignition switch is placed in the OFF
position.
The low fuel warning message shows in
the vehicle information display when the
amount of fuel in the tank is getting low. Refill the fuel tank before the gauge reg-
isters 0 (Empty).
The

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
