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

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 givenreception 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.

erational mode (if so equipped) is highly rec-
ommended. Exercise extreme caution at all
times so full attention may be given to ve-
hicle operation.
● If a conversation in a moving vehicle requires
you to take notes, pull off the road to a safe
location and stop your vehicle before doing
so.
CAUTION
● Keep the antenna as far away as possible
from the electronic control modules.
● Keep the antenna wire more than 8 in (20 cm)
away from the electronic control system har-
ness. Do not route the antenna wire next to
any harness.
● Adjust the antenna standing-wave ratio as
recommended by the manufacturer.
● Connect the ground wire from the CB radio
chassis to the body.
● For details, consult an INFINITI retailer.
WARNING
●Use a phone after stopping your vehicle in a
safe location. If you have to use a phone
while driving, exercise extreme caution at all
times so full attention may be given to ve-
hicle operation.
● If you find yourself unable to devote full at-
tention to vehicle operation while talking on
the phone, pull off the road to a safe location
and stop your vehicle before doing so.
CAUTION

vehicle phone module, no phone connecting
procedure is required. Your phone is automati-
cally connected with the in-vehicle phone mod- ule when the ignition switch is pushed to the
“ON” position with the registered cellular
phone turned on and carried in the vehicle.
You can register up to 5 different Bluetooth
cellular phones in the in-vehicle phone module.
However, you can talk on only one cellular
phone at a time.
When a call is active, the audio system and
microphone (located in the ceiling in front of the
rearview mirror) are used for the handsfree
communications.
If the audio system is being used at the time,
the audio mode will mute and will stay muted
until the active call is ended.
The INFINITI Voice Recognition system supports
the phone commands, so dialing a phone num-
ber using your voice is possible.
Before using the Bluetooth
Hands-Free Phone
System, refer to the following notes.
● Set up the wireless connection between a
cellular phone and the in-vehicle phone
module before using the Bluetooth Hands-
Free Phone System.
● Some Bluetooth enabled cellular phones
may not be recognized by the in-vehicle
phone module. ●
You will not be able to use a hands-free
phone under the following conditions:
– Your vehicle is outside of the telephone service area.
– Your vehicle is in an area where it is difficult to receive radio waves; such as in
a tunnel, in an underground parking ga-
rage, behind a tall building or in a moun-
tainous area.
– Your cellular phone is locked in order not to be dialed.
● When the radio wave condition is not ideal
or ambient sound is too loud, it may be
difficult to hear the other person’s voice
during a call.
● Immediately after the ignition switch is
pushed to the “ON” position, it may be
impossible to receive a call for a short period
of time.
● Do not place the cellular phone in an area
surrounded by metal or far away from the
in-vehicle phone module to prevent tone
quality degradation and wireless connection
disruption.
● While a cellular phone is connected through
the Bluetooth wireless connection, the bat-
tery power of the cellular phone may dis-
charge quicker than usual.

system asks the user to confirm.
NOTE:
When the user deletes a phone, the associated
phone book for that phone will also be deleted.
● Replace Phone
Use the Replace Phone command to change
the priority level of the active phone.
The priority level determines which phone is
active when more than one paired
Bluetooth phone is in the vehicle.
The system states the priority level of the
active phone and asks for a new priority
level (1, 2, 3, 4, 5).
If the new priority level is already being used
for another phone, the two phones will swap
priority levels.
For example, if the current priority levels are: Priority Level 1 = Phone A
Priority Level 2 = Phone B
Priority Level 3 = Phone C and you change the priority level of Phone C to
Level 1, then:
Priority Level 1 = Phone C
Priority Level 2 = Phone B
Priority Level 3 = Phone A

Use the Bluetooth On/Off command to turn
on/off Bluetooth Hands-Free Phone Sys-
tem.
● Help
The system announces the available com-
mands.
VOICE ADAPTATION MODE
The Voice Adaptation mode allows up to two
users with different dialects to train the system
to improve recognition accuracy. By repeating a
number of commands, the users can create a
voice model of their own voice that is stored in
the system. The system is capable of storing a
different voice adaptation model for each con-
nected phone.
Training procedure
1. Position the vehicle in a reasonably quiet outdoor location.
2. Sit in the driver’s seat with the engine running, the parking brake on, and the
transmission in Park. 3. Press the

WARNING
●Do not leave children or adults who would
normally require the support of others alone
in your vehicle. Pets should not be left alone
either. They could accidentally injure them-
selves or others through inadvertent opera-
tion of the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause severe
or possibly fatal injuries to people or
animals.
● Closely supervise children when they are
around cars to prevent them from playing
and becoming locked in the trunk where they
could be seriously injured. Keep the car
locked, with the rear seatback and trunk lid
securely latched when not in use, and pre-
vent children’s access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they contain
colorless and odorless carbon monoxide.
Carbon monoxide is dangerous. It can cause
unconsciousness or death. ●
If you suspect that exhaust fumes are enter-
ing the vehicle, drive with all windows fully
open, and have the vehicle inspected
immediately.
● Do not run the engine in closed spaces such
as a garage.
● Do not park the vehicle with the engine run-
ning for any extended length of time.
● Keep the trunk lid closed while driving, oth-
erwise exhaust gases could be drawn into
the passenger compartment. If you must
drive with the trunk lid open, follow these
precautions:
1. Open all the windows.
2. Set the
air recirculation to off and
the fan control to high to circulate the air.
● If electrical wiring or other cable connec-
tions must pass to a trailer through the seal
on the trunk lid or the body, follow the manu-
facturer’s recommendation to prevent car-
bon monoxide entry into the vehicle.
● The exhaust system and body should be in-
spected by a qualified mechanic whenever:
– The vehicle is raised for service.
– You suspect that exhaust fumes are en- tering into the passenger compartment. – You notice a change in the sound of the
exhaust system.
– You have had an accident involving dam- age to the exhaust system, underbody, or
rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust system are
very hot. Keep people, animals or flammable
materials away from the exhaust system
components.
● Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-2Starting and driving

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 your 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.
Additional information
●
The TPMS does not monitor the tire pressure
of the spare tire.
● The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h).
Starting and driving5-3

6. Turn on the hazard warning flashers andeither contact a roadside emergency ser-
vice to change the tire or see “CHANGING
A FLAT TIRE” in the “6. In case of emer-
gency” section of this Owner’s Manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces co-
ordination, delays reaction time and impairs
judgement. Driving after drinking alcohol in-
creases the likelihood of being involved in an
accident injuring yourself and others. Addition-
ally, if you are injured in an accident, alcohol
can increase the severity of the injury.
INFINITI is committed to safe driving. However,
you must choose not to drive under the influ-
ence of alcohol. Every year thousands of people
are injured or killed in alcohol-related acci-
dents. Although the local laws vary on what is
considered to be legally intoxicated, the fact is
that alcohol affects all people differently and
most people underestimate the effects of alco-
hol. Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter,
prescription, and illegal drugs). Don’t drive if
your ability to operate your vehicle is impaired
by alcohol, drugs, or some other physical con-
dition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS
WARNING
●
Do not drive beyond the performance capa-
bility of the tires, even with AWD engaged.
Accelerating quickly, sharp steering maneu-
vers or sudden braking may cause loss of
control.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Install tire chains on the rear wheels when
driving on slippery roads and drive carefully.
● This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in. ●
For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any D (Drive) or R (Re-
verse) position with the engine running. Do-
ing so may result in drivetrain damage or
unexpected vehicle movement which could
result in serious vehicle damage or personal
injury.
● Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer, (such as
the dynamometers used by some states for
emissions testing), or similar equipment
even if the other two wheels are raised off
the ground. Make sure you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
