key fob battery NISSAN SENTRA 2013 B17 / 7.G Owners Manual

WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
● The remote keyless entry keyfob trans-
mits radio waves when the buttons are
pressed. The FAA advises radio waves
may affect aircraft navigation and com-
munication systems. Do not operate the
remote keyless entry keyfob while on
an airplane. Make sure the buttons are
not operated unintentionally 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 keyfob from outside the vehicle.
Be sure to remove the key from the vehicle
before locking the doors.
The keyfob can operate at a distance of approxi-
mately 33 ft (10 m) from the vehicle. The effective
distance depends on the conditions around the
vehicle. As many as 5 keyfobs can be used with one
vehicle. For information concerning the purchase
and use of additional keyfobs, contact a NISSAN
dealer.
The keyfob will not function when:
● the battery is discharged
● the distance between the vehicle and the
keyfob is over 33 ft (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 keyfob:
● Do not allow the keyfob, which contains
electrical components, to come into
contact with water or salt water. This
could affect the system function.
● Do not drop the keyfob.
● Do not strike the keyfob sharply against
another object.
● Do not change or modify the keyfob.
● Wetting may damage the keyfob. If the
keyfob gets wet, immediately wipe until
it is completely dry. ●
Do not place the keyfob for an extended
period in an area where temperatures
exceed 140°F (60°C) .
● Do not attach the keyfob with a key
holder that contains a magnet.
● Do not place the keyfob near equip-
ment that produces a magnetic field,
such as a TV, audio equipment and per-
sonal computers.
If a keyfob is lost or stolen, NISSAN rec-
ommends erasing the ID code of that key-
fob. This will prevent the keyfob from un-
authorized use to unlock the vehicle. For
information regarding the erasing proce-
dure, please contact a NISSAN dealer.

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 inserting it into the key
hole, or use the remote keyless entry keyfob (if so
equipped) or the NISSAN Intelligent Key® (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and 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 maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires. 3. Tire chains may be used. For details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
● A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra washer fluid to refill the windshield-
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
● Wet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.

extends to approximately 10 m (33 ft)
from the vehicle. This range may vary
with conditions.
Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) this device
must accept any interference received, in-
cluding interference that may cause unde-
sired operation of the device.NISSAN INTELLIGENT KEY® (if so
equipped)
Replace the battery in the Intelligent Key as fol-
lows: 1. Remove the mechanical key from the Intelli- gent Key.
