3. Replace the battery with a new one.
Recommended battery: CR2032 or
equivalent.
.Do not touch the internal circuit andelectric terminals as it could cause a
malfunction.
.Hold the battery by the edges.
Holding the battery across the con-
tact points will seriously deplete the
storage capacity.
.Make sure that the + side faces thebottom of the case.SDI2452

Replacing
Fog may temporarily form inside the lens of
the exterior lights in the rain or in a car
wash. A temperature difference between
the inside and the outside of the lens
causes the fog. This is not a malfunction. If
large drops of water collect inside the lens,
contact an INFINITI retailer.
Xenon headlight bulb (if so equipped):
If replacement is required, see an INFINITI
retailer.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon headlights
replaced at an INFINITI retailer. For addi-
tional information, see “Headlight and turn
signal switch” (P.2-36).

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
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 CHECK TIRE
PRESSURE warning appears on the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
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 pressure (for
example a flat tire while driving).
For more details, see “Low tire pressure
warning light” (P.2-15),“Tire Pressure
Monitoring System (TPMS)” (P.5-4) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-2).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al- ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure”
heading. The
Tire and Loading 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 whendriven 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
moderate speeds.
Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.
WHEELS AND TIRES

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. certification label.
The vehicle weight capacity is
indicated on the Tire and Loading
Information label. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may re-
sult in reduced tire life, unsafe
operating conditions due to pre-
mature tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident.
Loading beyond the specified ca-
pacity may also result in failure of
other vehicle components.
. Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures are at the specified level.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.

*1Seating capacity: The maximum
number of occupants that can be
seated in the vehicle.
*2Vehicle load limit: See“Vehicle
loading information” (P.9-15).
*3Original size: The size of the tires
originally installed on the vehicle
at the factory.
*4Cold tire pressure: Inflate the
tires to this pressure when the
tires are cold. Tires are consid- ered 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 manufacturer to
provide the best balance of tire
wear, vehicle handling, driveabil-
ity, tire noise, etc., up to the
vehicle’s GVWR.

Checking the tire pressure
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, re-
position the gauge to eliminate
this leakage.
3.Remove the gauge.
4.Read the tire pressure on the
gauge stem and compare it to
the specification shown on the
Tire and Loading Information la-
bel.
5.Add air to the tire as needed. If
too much air is added, press the
core of the valve stem briefly with
the tip of the gauge stem to
release pressure. Recheck the
pressure and add or release air
as needed.
6.Install the valve stem cap.
7.Check the pressure of all other
tires, including the spare.
