2019 NISSAN ALTIMA Headrest

Af ter step 3 is performed, when the
ignition switch is pushed without de-
pressing the brake pedal, the ignition
switch position will change to the ON
position.
4. Push the ignition switch while depress- ing the brake pedal within 10 seconds
af ter the chime sounds. The engine will
start.
NOTE: ∙ When the ignition switch is pushed to
the ON position or the engine is
started by the above procedure, the
Intelligent Key battery discharge in-
dicator appears in the vehicle infor-
mation display even when the Intelli-
gent Key is inside the vehicle. This is
not a malfunction. To turn off the In-
telligent Key battery discharge indi-
cator, touch the ignition switch with
the Intelligent Key again.
∙ If the Intelligent Key battery dis-
charge indicator appears, replace the
battery as soon as possible. For addi-
tional information, refer to “Battery
replacement” in the “Do-it-yourself ”
section of this manual.NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the in-
terference) separate from the regis-
tered key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, coolant, brake fluid, and windshield-
washer fluid as frequently as possible,
or at least whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appear- ance and condition. Also check tires for
proper inflation.
∙ Lock all doors.
∙ Position seat and adjust headrests/ head restraints.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the ignition switch is pushed to
the ON position. For additional informa-
tion, refer to “Warning lights, indicator
lights and audible reminders” in the “In-
struments and controls” section of this
manual.
BEFORE STARTING THE ENGINE
5-16Starting and driving

Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc.
Accelerator pedal:Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Continuously Variable Transmission
(CVT) P (Park) position mechanism: On a
fairly steep hill check that the vehicle is held
securely with the shif t lever in the P (Park)
position without applying any brakes.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
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*: This vehicle is equipped with a
sealed maintenance free battery. It is rec-
ommended that you visit a NISSAN dealer
for service.
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.

WARNING
To ensure proper operation of the pas-
senger’s NISSAN Advanced Air Bag Sys-
tem, please observe the following
items.
∙ Do not allow a passenger in the rear
seat to push or pull on the seatback
pocket.
∙ Do not place heavy loads heavier than
9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
∙ Make sure that there is nothing press-
ing against the rear of the seatback,
such as a child restraint installed in
the rear seat or an object stored on
the floor.
∙ Make sure that there is no object
placed under the front passenger
seat.
∙ Make sure that there is no object
placed between the seat cushion and
center console or between the seat
cushion and the door.∙ If a forward facing child restraint is
installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts the
instrument panel. If the child restraint
does contact the instrument panel,
the system may determine the seat is
occupied and the passenger air bag
and passenger knee air bag may de-
ploy in a collision. Also the front pas-
senger air bag status light may not
illuminate. For additional information
about installing and using child re-
straints, refer to "Child restraints" in
this section.
∙ Confirm the operating condition with
the front passenger air bag status
light.
∙ If you notice that the front passenger
air bag status light is not operating as
described in this section, get the oc-
cupant classification system checked.
It is recommended that you visit a
NISSAN dealer for this service.
∙ Until you have confirmed with a
dealer that your passenger seat occu-
pant classification system is working
properly, position the occupants in
the rear seating positions.∙ Do not position the front passenger
seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may
flash.
This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada.However, all of the information,
cautions and warnings in this manual
still apply and must be followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
dashboard above the glove box. The front
air bags are designed to inflate in higher
severity frontal collisions, although they
may inflate if the forces in another type of
collision are similar to those of a higher
severity frontal impact. They may not in-
flate in certain frontal collisions.
