WINDOW ANTENNA
The antenna pattern is printed inside the
rear window.
CAUTION
.Do not place metalized film near the rear
window glass or attach any metal parts
to it. This may cause poor reception or
noise.
. When cleaning the inside of the rear
window, be careful not to scratch or
damage the rear window antenna.
Lightly wipe along the antenna with a
dampened soft cloth.

SATELLITE ANTENNA
There is a satellite antenna on the rear part
of the vehicle roof.
A buildup of ice on the satellite radio
antenna can affect satellite radio perfor-
mance. Remove the ice to restore satellite
radio reception. When installing a car phone or a CB radio
in your vehicle, be sure to observe the
following cautions, otherwise the new
equipment may adversely affect the elec-
tronic control modules and electronic con-
trol system harness.
WARNING
.
A cellular phone should not be used for
any purpose while driving so full atten-
tion may be given to vehicle operation.
Some jurisdictions prohibit the use of
cellular phones while driving.
. If you must make a call while your
vehicle is in motion, the hands-free
cellular phone operational mode (if so
equipped) is highly recommended. Ex-
ercise extreme caution at all times so full
attention may be given to vehicle opera-
tion.
. 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.

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
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
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 elec-
trical systems 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 retai-
ler.
. 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 SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended 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 pressure 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
pressure. 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.
If the vehicle is being driven with one or
more flat tires, the low tire pressure
warning light will illuminate continuously
and a chime will sound for 10 seconds. The
flat tire warning will also appear in the
vehicle information display. The chime will
only sound at the first indication of a flat
tire, and the warning light will illuminate
continuously. When the flat tire warning is
activated, have the system reset and the
tire checked and replaced if necessary by
an INFINITI retailer. Even if the tire is
inflated to the specified COLD tire pres-
sure, the warning light will continue to

illuminate until the system is reset by an
INFINITI retailer. Your vehicle can be driven
for a limited time on a flat tire. See“Run-
flat tires” (P.8-36).
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 com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions 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 prop- erly. 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 (if so
equipped).
. 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).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is
inflated to the recommended pressure,
the vehicle must be driven at speeds
above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
. The “Tire Pressure Low - Add Air”
warning appears in the vehicle informa-
tion display when the low tire pressure warning light is illuminated and low tire
pressure is detected. The
“Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light
turns off.
The “Tire Pressure Low - Add Air”
warning does not appear if the low tire
pressure warning light illuminates to
indicate a TPMS malfunction.
. The “Flat Tire - Visit dealer” warning
appears in the vehicle information dis-
play when the low tire pressure warn-
ing light is illuminated and one or more
flat tires are detected.
. Tire pressure rises and falls depending
on the heat caused by the vehicle’s
operation and the outside temperature.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If
the warning light illuminates in low
ambient temperature, check the tire
pressure for all four tires.
. You can also check the pressure of all
tires (except the spare tire) in the
vehicle information display. (See “Ve-
hicle information display” (P.2-20).)

WARNING
. Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufacturer
for the possible influences before use.
. If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure shown
on the Tire and Loading Information
label to turn the low tire pressure
warning light OFF. If the light still illuminates while driving after adjusting
the tire pressure, a tire may be flat. If
you have a flat tire, replace it with a
spare tire (if so equipped). (See
“Flat
tire” (P.6-3) for changing a flat tire.)
. Although you can continue driving with a
punctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and
personal injury. Also, driving a long
distance at high speeds may damage
the tires.
. Do not drive at speeds above 50 MPH
(80 km/h) and do not drive more than
approximately 93 miles (150 km) with a
punctured run-flat tire. The actual dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature,
vehicle load, road conditions and other
factors.
. If you detect any unusual sounds or
vibrations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously
damaged and need to be replaced.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function and the low tire pressure warning light
will flash for approximately 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.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CAUTION
.The TPMS may not function properly
when the wheels are equipped with tire
chains or the wheels are buried in snow.
. Do not place metalized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the
signals from the tire pressure sensors,
and the TPMS will not function properly.
Some devices and transmitters may tem-
porarily interfere with the operation of the

TPMS and cause the low tire pressure
warning light to illuminate. Some exam-
ples are:
.Facilities or electric devices using simi-
lar radio frequencies are near the
vehicle.
. If a transmitter set to similar frequen-
cies is being used in or near the
vehicle.
. If a computer (or similar equipment) or
a DC/AC converter is being used in or
near the vehicle.

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire,
the TPMS with Tire Inflation Indicator
provides visual and audible signals out-
side the vehicle to help you inflate the tires
to the recommended COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level
place.
2. Apply the parking brake and place the shift lever in the P (Park) position.
3. Place the ignition switch in the ON position. Do not start the engine.
Operation:
1. Add air to the tire. 2. After a few seconds, the hazard indica-
tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire.
. If the tire is over-inflated more than
approximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash 3
times. To correct the pressure, push the
core of the valve stem on the tire briefly
to release pressure. When the pressure
reaches the designated pressure, the
horn beeps once.
. If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates
that the Tire Inflation Indicator is not
operating.
. The TPMS will not activate the Tire
Inflation Indicator under the following
conditions:
— If there is interference from an
external device or transmitter
— The air pressure from the inflation
device such as those using a power
socket is not sufficient to inflate the
tire

RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a“blow-out”can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by
driving on under-inflated tires.
Rapid air pressure loss can affect the
handling and stability of the vehicle,
especially at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspect the tires for wear and
damage. See “Wheels and tires” (P.8-29) of
this manual.
If a tire rapidly loses air pressure or
“blows-out” while driving maintain control
of the vehicle by following the procedure
below. Please note that this procedure is
only a general guide. The vehicle must be
driven as appropriate based on the condi-
tions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a collision and result in personal injury.
.
The vehicle generally moves or pulls in
the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelerator
pedal.
. Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course.
3. When appropriate, slowly release the accelerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from
traffic if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emer-
gency service to change the tire or see
“Changing a flat tire” (P.6-4) 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
coordination, delays reaction time and im-
pairs judgement. Driving after drinking
alcohol increases the likelihood of being
involved in an accident injuring yourself and
others. Additionally, 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 influence of alcohol. Every year
thousands of people are injured or killed in
alcohol-related accidents. 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
alcohol.
Remember, drinking and driving don ’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs).

LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
. This system is only a warning device to
inform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or prevent loss of control. It
is the driver’ s responsibility to stay
alert, drive safely, keep the vehicle in
the traveling lane, and be in control of
the vehicle at all times.
. The system will not operate at speeds below approximately 45 MPH (70 km/h)
or if it cannot detect lane markers.
. If the LDW system malfunctions, it will
cancel automatically, and the LDW mal-
function message will appear in the
vehicle information display.
. If the LDW malfunction message ap-
pears, pull off the road to a safe location
and stop the vehicle. Turn the engine off
and restart the engine. If the LDW
malfunction message continues to ap-
pear, have the system checked by an
INFINITI retailer.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
The system may not function properly
under the following conditions:
.On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-stan-
dard lane markers; or lane markers
covered with water, dirt, snow, etc.
. On roads where the discontinued lane
markers are still detectable. .
On roads where there are sharp curves.
. On roads where there are sharply
contrasting objects, such as shadows,
snow, water, wheel ruts, seams or lines
remaining after road repairs. (The Lane
Departure Warning (LDW) system could
detect these items as lane markers.)
. On roads where the traveling lane
merges or separates.
. When the vehicle’s traveling direction
does not align with the lane marker.
. When traveling close to the vehicle in
front of you, which obstructs the lane
camera unit detection range.
. When rain, snow or dirt adheres to the
windshield in front of the lane camera
unit.
. When the headlights are not bright due
to dirt on the lens or if the aiming is not
adjusted properly.
. When strong light enters the lane
camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.)
. When a sudden change in brightness
occurs. (For example, when the vehicle
enters or exits a tunnel or under a
bridge.)
