WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar function
as outlined in this section could result in
serious injury or death.
• The sonar is a convenience feature. It is
not a substitute for proper parking.
• This function is designed as an aid to the
driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
• The driver is always responsible for
safety during parking and other
maneuvers.
• Always look around and check that it is
safe to move before parking.
• Read and understand the limitations of
the sonar as contained in this section.
The sonar function helps to inform the driver
of large stationary objects around the vehicle
when parking by issuing an audible and visual
alert.

OPERATING TIPS
The sensors,OAandOBon 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 outlets to ini-
tialize automatic heating mode. This is not a
malfunction. After the coolant 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.

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 automatic air
circulation control is activated, the sensor de-
tects odors outside the vehicle such as pulp or
chemicals, and exhaust such as gasoline or
diesel. When such odors or gases are de-
tected the display and the system automati-
cally change from fresh air mode to the recir-
culation 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.The automatic air recirculation mode can be
activated under the following conditions.
• The air flow control is not in the front de-
froster mode (the indicator light on the
front defroster button is turned off).
• The outside temperature is about 32°F (0°C) or more.

•When using a wheel without the TPMS
such as the spare tire, when a spare tire is
mounted or a wheel is replaced, tire pres-
sure 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. 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 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 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
warning 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.

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.
Starting and driving5-7

Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and press thepark button to engage 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 indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indi-
cators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more than ap-proximately 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 pres-
sure, 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.ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than pas-
senger cars to make them capable of per-
forming in a variety of on-pavement and off-
road applications. This gives them a higher
center of gravity than ordinary vehicles. An
advantage of higher ground clearance is a
better view of the road, allowing you to an-
ticipate problems. However, they are not de-
signed for cornering at the same speeds as
conventional 2-Wheel Drive vehicles any
more than low-slung sports cars are de-
signed to perform satisfactorily under off-
road conditions. If at all possible, avoid sharp
turns at high speeds. As with other vehicles of
this type, failure to operate this vehicle cor-
rectly may result in loss of control or vehicle
rollover.
In a rollover crash, an unbelted person is sig-
nificantly more likely to die than a person
wearing a seat belt.
For additional information, see “Driving
safety precautions” (P. 5-10).

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 for
proper 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
O1in-
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.

1. Side Indicator Light
2. BSW Indicator
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
O1
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, see
“BSW driving situations” (P. 5-49).

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the BSW system. Failure to operate the
vehicle in accordance with these system
limitations 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 over-
takes rapidly. –
A vehicle that passes through the de-
tection zone quickly.
– When overtaking several vehicles in a
row, the vehicles after the first ve-
hicle may not be detected if they are
traveling 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
detected. This is a normal operation
condition.
• The following conditions may reduce the
ability of the radar to detect other ve-
hicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on the
vehicle •
Do not attach stickers (including trans-
parent material), install accessories or
apply additional paint near the radar
sensors. 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.

which are approaching rapidly from behind.
Illustration 2:If the driver activates the turn
signal when another vehicle is in the detec-
tion zone, then the system chimes (twice) and
the side indicator light flashes.
NOTE:
• The radar sensors may not detect vehicles which are approaching rapidly from
behind.
• If the driver activates the turn signal be- fore a vehicle enters the detection zone,
the side indicator light will flash but no
chime will sound when the other vehicle is
detected.
