5. If the fuse is openOA, replace it with a
new fuse
OB.
6. If a new fuse also opens, have the electri- cal system checked and repaired. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
Fusible links
If the electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace with only Genuine NISSAN
parts.
PASSENGER COMPARTMENT
WARNING
Never use a fuse of higher or lower amper-
age rating than that specified on the fuse
box cover. This could damage the electrical
system or electronic control units or cause
a fire.
If any electrical equipment does not operate,
check for an open fuse.
NOTE:
The fuse box is located on the driver's side of
the instrument panel. 1. Be sure the ignition switch and the head-
light switch are OFF.
2. Remove the fuse box cover
OAwith a
suitable tool. Use a cloth to avoid damag-
ing the trim.
3. Locate the fuse that needs to be replaced.
4. Remove the fuse with the fuse puller
OB.

BATTERY REPLACEMENT
8-22Do-it-yourself

Replace the battery in the Intelligent Key as
follows:
1. Remove the mechanical key from the In-telligent Key.
2. Insert a small flathead screwdriver
OAinto
the slit
OBof the corner and twist it to
separate the upper part from the lower
part. Place a cloth over the screwdriver to
protect the casing. 3. Replace the battery with a new one.
Recommended battery: CR2032 or
equivalent.
• Do not touch the internal circuit and electric terminals as doing so could cause a
malfunction.
• Hold the battery by the edges. Holding the battery across the contact points will seri-
ously deplete the storage capacity.
• Make sure that the + side faces the bottom of the lower part.
4. Close the lid securely as illustrated with
OCandOD.
5. Operate the buttons to check the operation.
If you need assistance with replacement, it is
recommended that you visit an INFINITI re-
tailer for this service.

If you have a flat tire, see “Flat tire” (P. 6-3).
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all tires
except the spare. When the low tire
pressure warning light is lit and the
“Tire Pressure Low – Add Air” warning
appears in the vehicle information dis-
play, one or more of your tires is sig-
nificantly under-inflated. If equipped,
the system also displays pressure of all
tires (except the spare tire) on the dis- play screen by sending a signal from a
sensor that is installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16
mph (25 km/h). Also, this system may
not detect a sudden drop in tire pres-
sure (for example a flat tire while
driving).
For additional information, see “Low
tire pressure warning light” (P. 2-13),
“Tire Pressure Monitoring System
(TPMS)” (P. 5-5) and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label or the Tire and Loading In-
formation label under the “Cold Tire
Pressure” heading. The Tire and Load-
ing Information label is affixed to the
driver side center pillar. Tire pressures
should be checked regularly because:
• Most tires naturally lose air over
time.
• Tires can lose air suddenly when driven over potholes or other objects
or if the vehicle strikes a curb while
parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
see “TPMS with tire inflation indicator”
(P. 5-7).
WHEELS AND TIRES
Do-it-yourself8-27

Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING
• Improperly inflated tires can fail
suddenly and cause an accident.
•
The Gross Vehicle Weight Rating
(GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight ca-
pacity is indicated on the Tire and
Loading Information label. Do not
load your vehicle beyond this ca-
pacity. Overloading your vehicle
may result in reduced tire life, un-
safe operating conditions due to
premature tire failure, or unfavor-
able handling characteristics and
could also lead to a serious acci-
dent. Loading beyond the specified
capacity may also result in failure
of other vehicle components.
• Before taking a long trip, or when-
ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level.
• For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

1Seating capacity: The maximum
number of occupants that can be
seated in the vehicle.
2Original tire size: The size of the
tires originally installed on the ve-
hicle at the factory.
3Cold tire pressure: Inflate the tires
to this pressure when the tires are
cold. Tires are considered COLD
after the vehicle has been parked for 3 or more hours, or driven less
than 1 mile (1.6 km) at moderate
speeds. The recommended cold
tire inflation is set by the manufac-
turer to provide the best balance
of tire wear, vehicle handling,
driveability, tire noise, etc., up to
the vehicle's GVWR.4Tire size - see “Tire labeling”

Checking tire pressure
WARNING
• Driving at high speeds, 100 mph
(160 km/h) or higher sustained
where it is legal to do so, can cause
tires to have excessive heat build
up, which may result in a tire fail-
ure causing loss of control, crash,
injuries or even death. •
Some high-speed rated tires re-
quire inflation pressure adjust-
ment for high-speed operation.
When speed limits and road condi-
tions allow vehicle driving at high
speeds, make sure tires are rated
to support high speed operation,
tires are in optimal conditions and
pressure is adjusted to correct
cold inflation pressure for high
speed operation.
• If your vehicle is equipped with
P235/55RF19 or P255/45RF20
tire sizes, tires require adjustment
to the inflation pressure when
driving the vehicle at speeds of
100 mph (160 km/h) or higher
where it is legal to do so. Set the
cold inflation pressure to 36 psi
(250 kPa). •
After vehicle high speed operation
has ended, readjust the tire pres-
sure to the recommended cold in-
flation pressure. For additional in-
formation, see "Checking tire
pressure" (P. 8-30).
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely onto the valve stem. Do not press
too hard or force the valve stem
sideways, or air will escape. If the
hissing sound of air escaping from
the tire is heard while checking the
pressure, reposition the gauge to
eliminate this leakage.
3. Remove the gauge.
4. Read the tire pressure on the gauge stem and compare to the
specification shown on the Tire
and Loading Information label.
