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.

Illustration 3: If the BSI system is on and your
vehicle is approaching a lane marker and a
vehicle is in the detection zone, the system
chimes a sound (three times), and the side
indicator light flashes. Then the BSI system
slightly applies the brakes on one side to help
return the vehicle back to the center of the
driving lane.NOTE:

with a vehicle in the detection zone, the
other vehicle may not be detected.Overtaking another vehicle
Illustration 5: The side indicator light illumi-
nates if you overtake a vehicle and that ve-
hicle stays in the detection zone for approxi-
mately 3 seconds.
The radar sensors may not detect slower
moving vehicles if they are passed quickly.

∙ The radar sensors may be blocked bytemporary 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
radar sensors. Check for and remove ob-
jects obstructing the area around the ra-
dar sensors.
∙ Do not attach stickers (including trans- parent material), install accessories or
apply additional paint near the camera
unit or radar sensors.
∙ Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
∙ Do not strike or damage the area around the radar sensors. Do not touch the cam-
era lens or remove the screw located on
the camera unit. It is recommended that
you visit an INFINITI retailer if the camera
unit and/or area around the radar sen-
sors is damaged due to a collision.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the BCI system could
result in serious injury or death.
∙ The BCI system is not a replacement for
proper driving procedure, is not designed
to prevent contact with vehicles or ob-
jects and does not provide full brake
power. When backing out of a parking
space, always use the side and rear mir-
rors and turn and look in the direction you
will move. Never rely solely on the BCI
system.

BACKUP COLLISION INTERVENTION
(BCI) (if so equipped)
Starting and driving5-65

If the radar detects an approaching vehicle
from the side, the system chimes a sound
(single beep), the side indicator light on the
side of the approaching vehicle flashes and a
yellow rectangular frame appears in the dis-
play
A.NOTE:
∙ In the case of several vehicles approach-
ing in a row (Illustration 1) or in the op-
posite direction (Illustration 2), a chime
may not be sounded by the BCI system
after the first vehicle passes the sensors.
∙
The sonar system chime indicating there is
an object behind the vehicle has a higher
priority than the BCI chime (single beep)
indicating an approaching vehicle. If the
sonar system detects an object behind the
vehicle and the BCI system detects an ap-
proaching vehicle at the same time the fol-
lowing indicators are provided:
– The sonar system chime sounds
– The side indicator light on the side of
the approaching vehicle flashes and
– A yellow rectangular frame appears
in the display
If an approaching vehicle or object behind the
vehicle is detected when your vehicle is back-
ing up, a red frame will appear in the display
Aand the system will chime three times.
Then, the brakes will be applied momentarily.
After the automatic brake application, the
driver must depress the brake pedal to main-
tain brake pressure.

∙ 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. ∙ The sonar sensors detect stationary ob-
jects behind the vehicle. The sonar sensor
may not detect:
– Small or moving objects
– Wedge-shaped objects
– Objects close to the bumper (less than approximately 1 ft [30 cm])
– Thin objects such as rope, wire and chain, etc.
∙ The brake engagement by the BCI system is not as effective on a slope as it is on flat
ground. When on a steep slope the sys-
tem may not function properly.
∙ Do not use the BCI system under the fol- lowing conditions because the system
may not function properly:
– When driving with a tire that is not within normal tire conditions (e.g., tire
wear, low tire pressure, installation of
spare tire, tire chains, non-standard
wheels).
– When the vehicle is equipped with non-original brake parts or suspen-
sion parts.
∙ Do not use the BCI system when towing a trailer. ∙ Excessive noise (e.g., audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.
SYSTEM TEMPORARILY NOT
AVAILABLE
If the following messages appear on the ve-
hicle information display, a chime will sound
and the BCI system will be turned off auto-
matically:
∙ “Unavailable: High Accelerator Temp.”: If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then
started, the BCI system may be deacti-
vated automatically and the “Unavailable:
High Accelerator Temp” message will ap-
pear in the vehicle information display for
a period of time.
When the interior temperature is re-
duced, turn off the BCI system and turn it
on again.
∙ “Unavailable: Side Radar Obstruction”: When side radar blockage is detected.
When the blockage is removed, turn off
the BCI system and turn it on again.
5-72Starting and driving

If the radar sensorBdetects a slower mov-
ing vehicle ahead, the system will reduce the
vehicle speed so that your vehicle follows the
vehicle in front at the selected distance.
The system automatically controls the
throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.

Starting and driving5-87

Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and ICC sys-
tem display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing.
∙ When the vehicle ahead is traveling faster and the distance between vehicles
is increasing.
∙ When a vehicle cuts in near your vehicle. The warning chime will not sound when:
∙ The vehicle approaches other vehicles that are parked or moving slowly.
∙ The accelerator pedal is depressed, over- riding the system.
NOTE:
The approach warning chime may sound and
the system display may blink when the ICC
sensor detects objects on the side of the ve-
hicle or on the side of the road. This may
cause the ICC system to decelerate or accel-
erate the vehicle. The ICC sensor may detect
these objects when the vehicle is driven on
winding roads, narrow roads, hilly roads, or
when entering or exiting a curve. In these
cases you will have to manually control the
proper distance ahead of your vehicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
condition (for example, if a vehicle is being
driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed: ∙ When the vehicle ahead is not detected and your vehicle is traveling below the
speed of 15 mph (24 km/h)
∙ When the system judges the vehicle is at a standstill
∙ When the shift lever is not in the D (Drive) position or Manual mode
∙ When the electronic parking brake sys- tem is applied
∙ When the VDC system is turned off
∙ When VDC operates
∙ When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
∙ When a wheel slips
∙ When the radar signal is temporarily in- terrupted
