WARNING
.The sonar system is a convenience
but it is not a substitute for proper
parking. Always look around and
check that it is safe to do so before
parking. Always move slowly.
.Read and understand the limitations
of the sonar system as contained in
this section. Inclement weather may
affect the function of the sonar
system; this may include reduced
performance or a false activation..This system is not designed to pre-
vent contact with small or moving
objects.
.The system is designed as an aid to
the driver in detecting large station-
ary objects to help avoid damaging
the vehicle. The system will not
detect small objects below the bum-
per, and may not detect objects that
are too close to the bumper or on the
ground.
.If your vehicle sustains damage to the
bumper fascia, leaving it misaligned
or bent, the sensing zone may be
altered causing inaccurate measure-ment of obstacles or false alarms.
CAUTION
Keep the interior of the vehicle as quiet
as possible to hear the tone clearly.
The sonar system sounds a tone to warn the
driver of obstacles near the bumper. When
the [Auto Show Sonar Image] key is turned
on in the [Parking Sonar] settings, the sonar
indicator will also appear on the upper
display. (See “Sonar indicator” (P.5-138).)
The system detects front obstacles when the
shift lever is in the D (Drive) position or N
(Neutral) position. The system detects both
front and rear obstacles when the shift lever
is in the R (Reverse) position.
The system may not detect objects at speeds
above 6 MPH (10 km/h) and may not detect
certain angular or moving objects.
The sonar system detects obstacles up to
3.9 ft (1.2 m) from the bumper with a
decreased coverage area at the outer cor-
ners of the bumper. Refer to the illustration
for approximate zone coverage areas. As
you move closer to the obstacle, the rate of
the tone increases. When the obstacle is less
than 11.8 in (30 cm) away, the tone will

SONAR INDICATOR
When the corner of the vehicle moves closer
to an object, the corner sensor indicator
appears on the upper display.
When the center of the vehicle moves close
to an object, the center sensor indicator
appears on the upper display.
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 insert-
ing 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 informa-
tion, see “Engine cooling system” (P.8-3) or
“Intercooler cooling system” (P.8-5).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery 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, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system” (P.8-3).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide 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
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended you consult an INFINITI re-
tailer for the tire type, size, speed rating and
availability information.
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.
Tire chains may be used. For details, see
“Tire chains” (P.8-34) of this manual.
Intelligent All-Wheel Drive (AWD)
models
If you install snow tires, they must also be
the same size, brand, construction and tread
pattern on all four wheels.

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 precautions which
should be closely observed.
WARNING
.Park the vehicle on a level surface,
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 per-
forming any parts replacement or
repairs.
.Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
.Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
.If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other movingparts.
.It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
.Always wear eye protection when-
ever you work on your vehicle.
.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 warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
.Because the fuel lines are under high
pressure even when the engine is off,
it is recommended you visit an
INFINITI retailer for service of thefuel 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 en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal 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 INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-24).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could
affect your warranty coverage.If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.

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
in the vehicle information display. See “19.
Extended storage fuse warning” (P.2-24).
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 mal-
functions 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 tabs
found 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.

To replace the battery:
1. Release the lock knob at the back of the
Intelligent Key and remove the mechan-
ical key.
2. Insert a flat-blade screwdriver wrapped
with a cloth into the slit of the corner and
twist it to separate the upper part fromthe lower part.
3. Replace the battery with a new one.
Recommended battery:
CR2032 or equivalent
.Do not touch the internal circuit and
electric terminals as it could cause a
malfunction.
.Hold the battery by the edges. Hold-
ing the battery across the contact
points will seriously deplete the sto-
rage capacity.
.Make sure that the + side faces the
bottom of the case.
