Lockout protection
To prevent the Intelligent Key from being
accidentally locked in the trunk, lockout
protection is equipped with the Intelligent
Key.
When all doors are locked and the trunk lid
is closed with the Intelligent Key inside the
trunk, the outside buzzer will sound and the
trunk will open.
HOW TO USE THE REMOTE
KEYLESS ENTRY FUNCTION
The remote keyless entry function can op-
erate all door locks using the remote key-
less function of the Intelligent Key. The re-
mote keyless function can operate at a
distance of 33 f t (10 m) away from the ve-
hicle. The operating distance depends
upon the conditions around the vehicle.
The remote keyless entry function may not
function under the following conditions:∙ When the Intelligent Key is not within the operational range.
∙ When the doors or the trunk are open or not closed securely.
∙ When the Intelligent Key battery is dis- charged.
CAUTION
When locking the doors using the Intel-
ligent Key, be sure not to leave the key in
the vehicle.

position.
2. Close all doors.

button on the Intelli-
gent Key.

SYSTEM MAINTENANCE
The sonar sensors1are located on the
rear bumper. Always keep the area near
the sonar sensors clean.
The sonar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.
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 function on the Intelli-
gent 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.
