Action to take:
When the above conditions no longer
exist, the system will resume automati-
cally.
SYSTEM MAINTENANCE
The sonar sensors are located on the rear
bumpers. (See “Exterior rear” (P.0-4).)
.Always keep the area near the sonar
sensors clean.
. If the sonar sensors are dirty, wipe
them off with a soft cloth while being
careful to not damage them.
. The sonar sensors may be blocked by
temporary ambient conditions such
as splashing water, mist or fog. The
blocked condition may also be caused
by objects such as ice, frost or dirt
obstructing the sonar sensors. Check
for and remove objects obstructing
the area around the sonar sensors.
. Do not subject the area around the
sonar sensors to strong impact. Also,
do not remove or disassemble the
sonar sensors. If the sonar sensors
and peripheral areas are deformed in
an accident, etc., have the sonar
sensors checked by a NISSAN dealer.
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint on
the sonar sensors and their surround- ing areas. This may cause a malfunc-
tion or improper operation.
. When washing the vehicle using a
high-pressure washer, do not apply
direct washer pressure on the sonar
sensors. This may cause a malfunction
of the sonar sensors.
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 or the remote
keyless entry key fob.
ANTI-FREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check the anti-freeze 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
anti-freeze, drain the cooling system,
including the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).

off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, and
engine coolant and/or other ve-
hicle fluids can damage the en-
vironment. Always conform to
local regulations for disposal of
vehicle fluid.
. Never leave the engine or the CVT
related component harnesses
disconnected while the ignition
switch is in the ON position.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. 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.
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.10-21).)
You should be aware that incomplete or
improper servicing may result in operat-
ing difficulties or excessive emissions, and
could affect your warranty coverage.
If in
doubt about any servicing, it is recom-
mended you have it done by a NISSAN
dealer.

Remove the air duct if necessary.
To remove the air duct
:
1. Remove the clips
with a suitable
tool.
2. Loosen the bolt
with a suitable tool.
3. Pull the air duct upward and then sideways.
To install the air duct, perform the in-
stallation procedure in reverse order.

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 meter may
display a warning message. See “21. Ship-
ping Mode On Push Storage Fuse warn-
ing” (P.2-33).
If any electrical equipment does not
operate, remove the extended storage
fuse 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 headlights are off. (See “Headlight switch” (P.2-52) or “Intelli-
gent Auto Headlight system” (P.2-52).)
3. Remove the fuse box cover.
4. Pinch the locking tabs
found on
each side of the extended storage
fuse switch.
5. Pull the extended storage fuse switch straight out from the fuse box
.
CAUTION
.Be careful not to allow children to
swallow the battery and removed
parts.
. An improperly disposed battery
can harm the environment. Al-
ways confirm local regulations
for battery disposal.
. When changing batteries, do not
let dust or oil get on the compo-
nents.
. There is danger of explosion if the
lithium battery is incorrectly re-
placed. Replace only with the
same or equivalent type.

Replace the battery in the Intelligent Key
as follows:
1. Remove the mechanical key from the
Intelligent 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:
CR2032 or equivalent
.Do not touch the internal circuitand electric terminals as doing so
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.
