2019 NISSAN SENTRA key fob battery

DOME LIGHT
The interior light has a three-position
switch and operates regardless of ignition
switch position.
When the switch is in the ON position
1,
the interior lights illuminate, regardless of
door position. The lights will go off af ter a
period of time unless the ignition switch is
placed in the ACC or ON position. When the switch is in the DOOR position
2,
the interior lights will stay on for a period of
time when:
∙ The doors are unlocked by the key fob, a key, or the power door lock switch, while
all doors are closed and the ignition
switch is placed in the OFF position.
∙ The driver’s door is opened and then closed while the key is removed from
the ignition switch.
∙ The key is removed from the ignition switch while all doors are closed.
The lights will turn off while the timer is
activated when: ∙ The driver’s door is locked by the key fob, a key, or the power door lock switch.
∙ The ignition switch is placed in the ON position.
When the switch is in the OFF position
3,
the interior lights do not illuminate, regard-
less of door position. The lights will turn off automatically af ter a
period of time while doors are open to pre-
vent the battery from becoming dis-
charged.
CAUTION
Do not use for extended periods of time
with the engine stopped. This could re-
sult in a discharged battery.

WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙ The remote keyless entry key fob transmits radio waves when the but-
tons are pressed. The FAA advises ra-
dio waves may affect aircraf t naviga-
tion and communication systems. Do
not operate the remote keyless entry
key fob while on an airplane. Make
sure the buttons are not operated un-
intentionally when the unit is stored
for a flight.
It is possible to lock/unlock all doors, turn
the interior lights on, and activate the panic
alarm by using the key fob from outside the
vehicle.
Be sure to remove the key from the ve-
hicle before locking the doors.
The key fob can operate at a distance of
approximately 33 f t (10 m) from the vehicle.
The effective distance depends on the
conditions around the vehicle. As many as four key fobs can be used with
one vehicle. For information concerning
the purchase and use of additional key
fobs, it is recommended that you visit a
NISSAN dealer.
The key fob will not function when:
∙ The battery is discharged.
∙ The distance between the vehicle and the key fob is over 33 f t (10 m).
The panic alarm will not activate when
the key is in the ignition switch.
CAUTION
Listed below are conditions or occur-
rences which will damage the key fob:
∙ Do not allow the key fob, which con- tains electrical components, to come
into contact with water or salt water.
This could affect the system function.
∙ Do not drop the key fob.
∙ Do not strike the key fob sharply against another object.
∙ Do not change or modif y the key fob.
∙ Wetting may damage the key fob. If the key fob gets wet, immediately
wipe until it is completely dry. ∙ Do not place the key fob for an ex-
tended period in an area where tem-
peratures exceed 140°F (60°C).
∙ Do not attach the key fob with a key holder that contains a magnet.
∙ Do not place the key fob near equip- ment that produces a magnetic field,
such as a TV, audio equipment and
personal computers.
If a key fob is lost or stolen, NISSAN rec-
ommends erasing the ID code of that
key fob. This will prevent the key fob
from unauthorized use to unlock the
vehicle. For information regarding the
erasing procedure, it is recommended
that you visit a NISSAN dealer.
REMOTE KEYLESS ENTRY SYSTEM (if
so equipped)
3-8Pre-driving checks and adjustments

∙ When driving on extremely inclinedsurfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate. Do not drive on these
types of roads.
∙ When driving on an unstable surface such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash or the
indicator light may
illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface.
∙ If wheels or tires other than the NISSAN recommended ones are used,
the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole, or use the re-
mote keyless entry key fob or the NISSAN
Intelligent Key®.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, refer to “Battery”
in the “Do-it-yourself ” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, refer
to “Changing engine coolant” in the “Do-it-
yourself ” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance
of these tires will be substantially re-
duced in snowy and icy conditions. If
you operate your vehicle on snowy or
icy roads, NISSAN recommends the use
of MUD & SNOW or ALL SEASON TIRES
on all four wheels. It is recommended
that you visit a NISSAN dealer for the tire
type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
