TURNING ON AND OFF THE SONAR
FUNCTION
When the “P” keyis touched, the
indicator lighton the key will turn off
and the sonar will turn off temporarily.
The Moving Object Detection (MOD) (if so
equipped), the Rear Automatic Braking
(RAB), and the Intelligent Back-up Inter-
vention (I-BI) (if so equipped) systems will
also be turned off at the same time. See
“Moving Object Detection (MOD)” (P.4-29),
“Rear Automatic Braking (RAB)” (P.5-116)
and “Intelligent Back-up Intervention (I-
BI)” (P.5-63).
When the “P” key
is touched again, the
indicator lightwill turn on and the sonar will turn back on.
In the cases below, the sonar will be
turned back on automatically:
.
When the shift lever is in the R
(Reverse) position.
. When the CAMERA button is pushed
and a screen other than the camera
view is shown on the display.
. When vehicle speed decreases below
approximately 5 MPH (8 km/h).
. When the ignition switch is placed in
the OFF position and turned back to
the ON position again.
To prevent the sonar system from acti-
vating altogether, use the sonar system
settings menu. See “Sonar function set-
tings” (P.4-26).
When both Sonar and the MOD system
are deactivated from the settings menu,
the "P" key
will disappear from the
display. (See “Sonar function settings”
(P.4-26) and “MOD function settings” (P.4-
32).)

VEHICLE DYNAMIC CONTROL (VDC)
OFF SWITCH
The vehicle should be driven with the
Vehicle Dynamic Control (VDC) system ON
for most driving conditions.
When the vehicle is stuck in mud or snow,
the VDC system reduces the engine out-
put to reduce wheel spin. The engine
speed will be reduced even if the accel-
erator is depressed to the floor. If max-
imum engine power is needed to free a
stuck vehicle, turn the VDC system off.
To turn off the Vehicle Dynamic Control
(VDC) system, push the VDC OFF switch.
The VDC off indicator light
will
illuminate. Push the VDC OFF switch again or restart
the engine to turn ON the system.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing,
apply deicer through the key hole. If the
lock becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check antifreeze to assure
proper winter protection. For additional
information, see “Engine cooling system”
(P.8-4).
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, see “Battery”
(P.8-11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always
take care to prevent serious accidental
injury to yourself or damage to the
vehicle. The following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
Move the shift lever to P (Park).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing near the fan. .
Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items
which are relatively easy for an owner to
perform.
A genuine NISSAN Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-40).)
You should be aware that incomplete or
improper servicing may result in operat-
ing difficulties or excessive emissions, and

Extended storage fuse switch (if so
equipped)
To reduce battery drain, the extended
storage fuse switch comes from the
factory switched off. Prior to delivery of
your vehicle, the switch is pushed in
(switched on) and should always remain
on.
If the extended storage fuse switch is not
pushed in (switched on), the “Shipping
Mode On, Push Storage Fuse” warning
may appear on the vehicle information
display (if so equipped). See “Vehicle
information display” (P.2-19).
If any electrical equipment does not
operate, remove the extended storagefuse switch and check for an open fuse.
NOTE:
If the extended storage fuse switch
malfunctions or if the fuse is open, it is
not necessary to replace the switch. In
this case, remove the extended storage
fuse switch and replace it with a new
fuse of the same rating.
How to remove the extended storage
fuse switch:
1. To remove the extended storage fuse
switch, be sure the ignition switch is in
the OFF or LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabsfound on
each side of the storage fuse switch.
5. Pull the storage fuse switch straight out from the fuse box
.
CAUTION
Be careful not to allow children to
swallow the battery and removed
parts.

SDI2451
Replace the battery as follows:
1. Release the lock knob at the back ofthe Intelligent Key and remove the
mechanical key.
2. Insert a small screwdriver into the slit of the corner and twist it to separate
the upper part from the lower part. Use a cloth to protect the casing.
3. Replace the battery with a new one. Recommended battery: CR2025 or
equivalent.
.Do not touch the internal circuitand electric terminals as it could
cause a malfunction.
.Hold the battery by the edges.
Holding the battery across the
contact points will seriously deplete
the storage capacity.
.Make sure that the + side faces the bottom of the case.

4. Align the tips of the upper and lower
parts, and then push them together
until it is securely closed.
5. Push the buttons two or three times to check its operation.
If you need any assistance for replace-
ment, it is recommended you visit a
NISSAN dealer for this service.
