If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inaccu-
rate measurement of obstacles or false
alarms.
CAUTION
• Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
• Keep the sonar sensors (located on the
bumper fascias) free from snow, ice and
large accumulations of dirt. Do not clean
the sensors with sharp objects. If the
sensors are covered, the accuracy of the
sonar function will be diminished.
SYSTEM OPERATION
1Center sonar sensors
2Corner sonar sensors
The system informs with a visual and audible
alert of:
• front obstacles when the shift lever is in the D (Drive) position
• front and rear obstacles when the shift le- ver is in the R (Reverse) position How the system alerts of obstacles:
The system is deactivated at speeds above 6
mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after several
seconds when the obstacle is identified only
with the center sensor. The tone will stop
when the obstacle gets away from the
vehicle.
When the object is detected, the indicator
(green) appears and blinks and the tone
sounds intermittently. When the vehicle
moves closer to the object, the color of the
indicator turns yellow and the rate of the
blinking increases. When the vehicle is very
close to the object, the indicator stops blink-
ing and turns red, and the tone sounds
continuously.

•The system is not designed to prevent
contact with small or moving objects. Al-
ways move slowly. The system will not
detect small objects below the bumper or
on the ground.
• The system may not detect the following
objects: fluffy objects such as snow,
cloth, cotton, glass-wool, etc.; thin ob-
jects such as rope, wire and chain, etc.; or
wedge-shaped objects; complex-shaped
objects or multiple objects in close.
• The sonar system may not detect objects
at speeds above 3 mph (5 km/h) and may
not detect certain angular or moving
objects.
• The sonar system may not operate in the
following conditions:
– When rain, snow, ice, dirt, etc. ad- heres to the sonar.
– When a loud sound is heard in the area around the vehicle.
– When the surface of the obstacle is diagonal to the front or rear of the
vehicle.
– When a sonar or the area around the sensor is extremely hot or cold. •
The sonar system may unintentionally
operate in the following conditions:
– When there is overgrown grass in the area around the vehicle.
– When there are bumps, protrusions or manhole covers on the road
surface.
– When the vehicle drives through a draped flag or a curtain.
– When there is an accumulation of snow or ice behind the vehicle.
– When driving on a steep hill.
SYSTEM TEMPORARILY
UNAVAILABLE
When sonar blockage is detected, the system
will be deactivated automatically.
The system is not available until the condi-
tions no longer exist.
The sonar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog. The blocked condition
may also be caused by objects such as ice,
frost or dirt obstructing the sonar sensors.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
SYSTEM MAINTENANCE
The sonar sensorsOAandOBare located on
the front and rear bumpers.
• Always keep the area near the sonar sen- sors clean.

• If the sonar sensors are dirty, wipe them offwith a soft cloth while being careful to not
damage them.
• The sonar sensors may be blocked by tem- porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the sonar sen-
sors. Check for and remove objects ob-
structing the area around the sonar
sensors.
• Do not subject the area around the sonar sensors to strong impact. Also, do not re-
move or disassemble the sonar sensors. If
the sonar sensors and peripheral areas are
deformed in an accident, etc., have the so-
nar sensors checked by an INFINITI retailer.
• Do not attach stickers (including transpar- ent material), install accessories or apply
additional paint on the sonar sensors and
their surrounding areas. This may cause a
malfunction or improper operation.
• When washing the vehicle using a high- pressure washer, do not apply direct
washer pressure on the sonar sensors. This
may cause a malfunction of the sonar
sensors. The Idling Stop System activates to prevent
unnecessary fuel consumption, exhaust
emissions and noise.
