OPERATING TIPS
The sensors,AandBon the instrument
panel, help the system maintain a constant
temperature. Do not put anything on or
around these sensors. ∙ When the engine coolant temperature
and outside air temperature are low, the
air may flow from defroster or foot out-
lets to initialize automatic heating mode.
This is not a malfunction. After the cool-
ant temperature warms up, air will flow
normally from the foot outlets.
∙ A visible mist may be seen coming from the ventilators in hot, humid conditions as
the air is cooled rapidly. This does not
indicate a malfunction.

Automatic Climate Control System
(if so equipped)
The Automatic Climate Control System
keeps the air inside of the vehicle clean, using
the automatic air recirculation control with
the exhaust gas/outside odor detecting sen-
sor with ion control.
1Auto Recirc key
Touch to turn on the automatic recirculation
mode.
2Plasmacluster® icon
Indicates the Plasmacluster® ion emission
status.
Ion control:
The Automatic Climate Control System unit
generates highly concentrated Plasmaclus-
ter® ions into the air blown from the ventila-
tors to reduce odor absorbed into the interior
trim and to suppress airborne bacteria. The high-density Plasmacluster®ions also have a
proven skin moisture preserving effect.
The Plasmacluster® icon on the CLIMATE
screen indicates the status of the Plasma-
cluster® ion emission from the system and
changes with the amount of the air flow.
Automatic air recirculation control with the
exhaust gas/outside odor detection sensor:
The Automatic Climate Control System
comes with an exhaust gas
detection/outside odor sensor. When the au-
tomatic air circulation control is activated, the
sensor detects odors outside the vehicle such
as pulp or chemicals, and exhaust such as
gasoline or diesel. When such odors or gases
are detected the display and the system au-
tomatically change from fresh air mode to the
recirculation mode.
When the automatic air recirculation is on, for
the first 5 minutes, the air recirculation mode
is selected to prevent dust, dirt, and pollen
from entering the vehicle and to clean the air
inside of the vehicle.
After 5 minutes, the sensor detects exhaust
gas and automatically alternates between
the air recirculation mode and the fresh air
mode.

∙ 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 system.
– 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 Indica- tor does not operate due to TPMS
interference, 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.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the BSW system
could result in serious injury or death.
∙ The BSW system is not a replacement forproper driving procedures and is not de-
signed to prevent contact with vehicles
or objects. When changing lanes, always
use the side and rear mirrors and turn and
look in the direction your vehicle will
move to ensure it is safe to change lanes.
Never rely solely on the BSW system.
The BSW system helps alert the driver of
other vehicles in adjacent lanes when chang-
ing lanes. The BSW system uses radar sensors
1in-
stalled near the rear bumper to detect other
vehicles in an adjacent lane. The radar sensors can detect vehicles on ei-
ther side of your vehicle within the detection
zone shown as illustrated. This detection
zone starts from the outside mirror of your
vehicle and extends approximately 10 ft
(3.0 m) behind the rear bumper, and approxi-
mately 10 ft (3.0 m) sideways.

BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 mph (32 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
1
illuminates. If the turn signal is then activated,
the system chimes (twice) and the side indi-
cator light flashes. The side indicator light
continues to flash until the detected vehicle
leaves the detection zone.
The side indicator light illuminates for a few
seconds when the ignition switch is placed in
the ON position.
The brightness of the side indicator light is
adjusted automatically depending on the
brightness of the ambient light.
If a vehicle comes into the detection zone
after the driver activates the turn signal, then
only the side indicator light flashes and no
chime sounds. For additional information, re-
fer to “BSW driving situations” in this section.

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the BSW system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
∙ The BSW system cannot detect all ve-hicles under all conditions.
∙ The radar sensors may not be able to de- tect and activate BSW when certain ob-
jects are present such as:
– Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low height vehicles, or high ground clear-
ance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detection zone when you accelerate from a stop.
– A vehicle merging into an adjacent lane at a speed approximately the
same as your vehicle.
– A vehicle approaching rapidly from behind. – A vehicle which your vehicle overtakes
rapidly.
– A vehicle that passes through the de- tection zone quickly.
– When overtaking several vehicles in a row, the vehicles after the first vehicle
may not be detected if they are trav-
eling close together.
∙ The radar sensors’ detection zone is de- signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an ad-
jacent lane. When driving in a narrow
lane, the radar sensors may detect ve-
hicles driving two lanes away.
∙ The radar sensors are designed to ignore most stationary objects; however, ob-
jects such as guardrails, walls, foliage and
parked vehicles may occasionally be de-
tected. This is a normal operation
condition.
∙ The following conditions may reduce the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray – Ice/frost/dirt build-up on the vehicle
∙ Do not attach stickers (including trans- parent material), install accessories or
apply additional paint near the radar sen-
sors. These conditions may reduce the
ability of the radar to detect other
vehicles.
∙ Excessive noise (for example, audio sys- tem volume, open vehicle window) will
interfere with the chime sound, and it
may not be heard.
