WARNING
∙ Do not leave children or adults whowould normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acciden-
tally injure themselves or others through
inadvertent operation 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.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; they con-tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous. It
can cause unconsciousness or death.
∙ If you suspect that exhaust fumes are en- tering 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 running for any extended length of time.
∙ Keep the rear vent windows, liftgates, doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passenger
compartment. If you must drive with one
of these open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation button
to off and the fan control dial to high
to circulate the air.
∙ If electrical wiring or other cable connec- tions must pass to a trailer through the
seal on the liftgate or the body, follow
the manufacturer’s recommendation to
prevent carbon monoxide entry into the
vehicle.
∙ The exhaust system and body should be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service. b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
∙ The exhaust gas and the exhaust systemare very hot. Keep people, animals or
flammable materials away from the ex-
haust 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
5-4Starting and driving

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will 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
systems can cause over rich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that you visit an INFINITI retailer for this
service.
∙ 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 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 Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all 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. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’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
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 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 en-
sure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Starting and driving5-5

Additional information:∙ When replacing a wheel without the TPMS such as the spare tire, 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). Also, this system may not de-
tect 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 in-
flated 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” warn- ing appears in the vehicle information
display when the low tire pressure warn-
ing light is illuminated and low tire pres-
sure 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” warn-
ing appears each time the ignition switch
is in the ON position as long as the low
tire pressure warning light remains illumi-
nated.
∙ The “Tire Pressure Low — Add Air” warn- ing does not appear if the low tire pres-
sure warning light illuminates to indicate
a TPMS malfunction.
∙ Tire pressure rises and falls depending on the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure after driving be-
cause the tire pressure rises after driving.
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, check the tire
pressure for all four tires.
∙ The Tire and Loading Information label is located in the driver’s door opening.
∙ You can also check the pressure of all tires (except the spare tire) on the vehicle
information display screen. The order of
the tire pressure figures displayed on the
screen corresponds with the actual order
of the tire position. For additional information, refer to “Low tire
pressure warning light” and “Tire Pressure
Low — Add Air” in the “Instruments and con-
trols” section and “Tire Pressure Monitoring
System (TPMS)” in the “In case of emergency”
section of this manual.
WARNING
∙ Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
5-6Starting and driving

∙ If the low tire pressure warning light illu-minates 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 recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
off. If you have a flat tire, replace it with a
replacement tire as soon as possible. (For
additional information, refer to “Flat
tire” in the “In case of emergency” section
for changing a flat tire.) ∙ When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is re-
placed, tire pressure will not be indicated,
the TPMS will not function and the low
tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Have your tires
replaced and/or TPMS system reset as
soon as possible. It is recommended that
you visit an INFINITI retailer for this
service.
∙ 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 properlywhen 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 sig-
nals from the tire pressure sensors, and
the TPMS will not function properly. Some devices and transmitters may tempo-
rarily interfere with the operation of the
TPMS and cause the low tire pressure warn-
ing light to illuminate.
Some examples are:
∙ Facilities or electric devices using similar radio frequencies are near the vehicle.
∙ If a transmitter set to similar frequencies 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.
The low tire pressure warning light may illu-
minate in the following cases: ∙ If the vehicle is equipped with a wheel and tire without TPMS.
∙ If the TPMS has been replaced and the ID has not been registered.
∙ If the wheel is not originally specified by INFINITI.

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire, the
TPMS with Tire Inflation Indicator provides
visual and audible signals outside the vehicle
to help you inflate the tires to the recom-
mended 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 posi- tion. 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 thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three 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 TPMS with Tire Inflation Indi-
cator is not operating.
∙ The TPMS will not activate the TPMS with Tire Inflation Indicator under the
following conditions:
– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation de- vice is not sufficient to inflate the tire.
– There is a malfunction in the TPMS.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor is low.
∙
If the TPMS with Tire Inflation Indicator
does not operate due to TPMS interfer-
ence, move the vehicle about 3 ft (1 m)
backward or forward and try again.
If the TPMS with Tire Inflation Indicator is
not working, use a tire pressure gauge.
