FUEL GAUGE
The gauge indicates theapproximatefuel level
in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down hills.
The gauge needle returns to 0 (Empty) after the
ignition switch is pushed to the OFF position.
Refill the fuel tank before the gauge registers
“0” (Empty).
The low fuel warning
appears on the dot
matrix liquid crystal display when the fuel tank
is getting low. Refuel as soon as it is conve-
nient, preferably before the gauge reaches “0”. There will be a small reserve of fuel in the tank
when the fuel gauge needle reaches “0”.
The
indicates that the fuel-filler door is
located on the driver’s side of the vehicle.
CAUTION
● If the vehicle runs out of fuel, themalfunction indicator light (MIL) may come
on. Refuel as soon as possible. After a few
driving trips, the
light should turn off.
If the light remains on after a few driving
trips, have the vehicle inspected by an
INFINITI retailer.
● For additional information, see “Malfunction
Indicator Light (MIL)” later in this section.
ENGINE OIL PRESSURE GAUGE
The gauge indicates the engine lubrication sys-
tem oil pressure while the engine is running.
When the engine speed is high, the engine oil
pressure is also high. When it is low, the gauge
indicates the low (L) oil pressure.
The engine oil pressure is normal when the
gauge needle points within the zone
1shown
in the illustration.
CAUTION
● This gauge is not designed to indicate low
engine oil level. Use the dipstick to check
the oil level. (See “ENGINE OIL” in the “8.
Maintenance and do-it-yourself” section.)

The unit can be converted between “US” and
“Metric”. (See “HOW TO USE SETTING BUTTON”
later in this section.)
The fuel economy information may differ from
the information displayed on the vehicle infor-
mation display. This is due to the timing differ-
ence in updating the information and does not
indicate a malfunction.
TIRE PRESSURE information
WARNING
●When a spare tire is mounted or a wheel is
replaced, tire pressure will not be indicated,
the TPMS will not function and the low tire
pressure warning light will flash for approxi-
mately 1 minute. The light will remain on
after 1 minute. Contact your INFINITI retailer
as soon as possible for tire replacement
and/or system resetting. ●
Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
The tire pressure will be displayed for refer-
ence.
The pressure indication “** kPa” or “** psi” on
the screen means that the pressure is being
measured. After a few driving trips, the pres-
sure for each tire will be displayed.
To change the measurement units, select the
“Select Units” key with the INFINITI controller
and push the ENTER button.
In case of low tire pressure, LOW PRESSURE
information will be displayed on the screen.
Check the pressure of all tires.
Tire pressure rises and falls depending on the
heat caused by the vehicle’s traveling condition
and the temperature.

SERVICING CLIMATE CONTROL
The climate control system in your INFINITI is
charged with a refrigerant designed with the
environment in mind.This refrigerant will not
harm the earth’s ozone layer. However, special
charging equipment and lubricant are required
when servicing your INFINITI air conditioner.
Using improper refrigerants or lubricants will
cause severe damage to your climate control
system. (See “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section for climate con-
trol system refrigerant and lubricant recommen-
dations.)
Your INFINITI retailer will be able to service your
environmentally friendly climate control sys-
tem.
WARNING
The system contains refrigerant under high
pressure. To avoid personal injury, any air con-
ditioner service should be done only by an ex-
perienced technician with the proper
equipment.
AUDIO OPERATION PRECAUTIONS
Radio
Push the ignition switch to the ACC or ON
position and push the radio band select button
to turn on the radio. If you listen to the radio
with the engine not running, the ignition switch
should be pushed to the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external
influences. Intermittent changes in reception
quality normally are caused by these external
influences.
Using a cellular phone in or near the vehicle may
influence radio reception quality.
Radio reception :
Your INFINITI radio system is equipped with
state-of-the-art electronic circuits to enhance
radio reception. These circuits are designed to
extend reception range, and to enhance the
quality of that reception. However there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle,
even when the finest equipment is used. These
characteristics are completely normal in a given
reception area, and do not indicate any mal-
function in your INFINITI radio system.
Reception conditions will constantly change
because of vehicle movement. Buildings, ter-
rain, signal distance and interference from
other vehicles can work against ideal reception.
Described below are some of the factors that
can affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the
device in a different location may reduce or
eliminate the noise.

CAUTION
●Do not use leaded gasoline. Deposits from
leaded gasoline seriously reduce the three-
way catalyst’s ability to help reduce exhaust
pollutants.
● Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems can cause overrich fuel flow into the
three-way catalyst, causing it to overheat.
Do not keep driving if the engine misfires, or
if noticeable loss of performance or other
unusual operating conditions are detected.
Have the vehicle inspected promptly by an
INFINITI retailer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-way
catalyst.
● Do not race the engine while warming it up.
● Do not push or tow your vehicle to start the
engine.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check all 4 tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Starting and driving5-3

The IBA system will remain in the last ON or OFF
state it was left in until it is manually changed
by pressing the IBA OFF switch.
Illumination of the IBA OFF indicator light with-
out a beep sound is an indication that the IBA
system is temporarily unavailable. It will occur
under the following conditions:
– When driving into a strong light (for example,sunlight)
– When the 4WD shift switch is in the 4H or 4L position (for 4WD models)
The IBA OFF indicator light will turn off when the
system returns to its normal operating condi-
tions.
For the sensor maintenance, see “Sensor main-
tenance” earlier in this section.CAUTION
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle.
Failure to follow these recommendations may
result in shortened engine life and reduced en-
gine performance.
● Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 miles
(805 km). ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
● Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
● Select a gear range suitable to road condi-
tions.
● Avoid unnecessary prolonged engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated at the correct pres-
sure. Improper tire pressure will increase
wear and waste fuel.
● Make sure the front wheels are properly
aligned. Improper alignment will cause pre-
mature tire wear and lower fuel economy.
● Climate control operation lowers fuel
economy. Use the air conditioner only when
necessary.
● When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
