and low tire pressure is detected. The CHECK
TIRE PRESSURE warning turns off when the
low tire pressure warning light turns off.
The CHECK TIRE PRESSURE warning does not
appear if the low tire pressure warning light
illuminates to indicate a TPMS malfunction.
● Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. 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 illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires.
For additional information, see “Low tire pres-
sure warning light” in the “2. Instruments and
controls” section and “TIRE PRESSURE MONI-
TORING SYSTEM (TPMS)” in the “6. In case of
emergency” section.WARNING
● If the low tire pressure warning light illumi-
nates 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 recommended COLD tire
pressure shown on the Tire and Loading In-
formation label to turn the low tire pressure
warning light OFF. If the light still illumi-
nates while driving after adjusting the tire
pressure, a tire may be flat. If you have a flat
tire, replace it with a spare tire as soon as
possible. (See “FLAT TIRE” in the “6. In case
of emergency” section for changing a flat
tire.)
● When a spare tire is mounted or a wheel is
replaced, 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. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting. ●
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 signals from
the tire pressure sensors, and the TPMS will
not function properly.
Some devices and transmitters may temporarily
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.
5-4Starting and driving

The Blind Spot Warning (BSW) system can help
alert the driver of other vehicles in adjacent
lanes when changing lanes.The BSW system uses radar sensors
Ain-
stalled near the rear bumper to detect other
vehicles beside your vehicle in an adjacent
lane. The radar sensors can detect vehicles on either
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 approximately 10 ft (3.0 m)
sideways.
The BSW system operates above approximately
20 MPH (32 km/h). If the radar sensors detect a
vehicle in the detection zone, the BSW indicator
light illuminates. If the driver then activates the
turn signal, a chime will sound twice and the
BSW indicator light will flash.

WARNING
●The BSW system is not a replacement for
proper driving procedure 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 you will move to ensure it is
safe to change lanes. Never rely solely on the
BSW system.
● The BSW system may not provide a warning
for vehicles that pass through the detection
zone quickly.
BSW SYSTEM OPERATION
If the radar sensors detect a vehicle in the
detection zone, the BSW indicator light next to
the outside mirror will illuminate in the direc-
tion of the detected vehicle. If the turn signal is
then activated, the BSW indicator light flashes
and a chime sounds twice. The indicator light
continues to flash until the detected vehicle
leaves the detection zone.
The BSW indicator lights illuminate for a few
seconds when the ignition switch is pushed to
the ON position.

5-26Starting and driving

The brightness of the BSW indicator lights is
adjusted automatically depending on the
brightness of the ambient light.
A chime sounds if the radar sensors have
already detected vehicles when the driver acti-
vates the turn signal. If a vehicle comes into the
detection zone after the driver activates the turn
signal, then only the BSW indicator light flashes
and no chime sounds. (See “BSW DRIVING
SITUATIONS” later in this section)
The BSW system is automatically turned on
when the engine is started and the warning
systems ON indicator light
1illuminates on
the switch. You can turn the BSW system off by
pushing the warning systems switch on the
instrumental panel. This switch will turn on and
off the LDW, BSW and FCW systems at the same
time.
NOTE:
If you continue to push the warning systems
switch from off to on for over 4 seconds, a chime
will sound. This will change the default status of
the LDW, BSW and FCW systems to OFF so that
these systems will not automatically turn on
when the engine is started. If this procedure is
repeated, the default status will return to ON.
WARNING
● Do not use the BSW system when towing a
trailer because the system may not function
properly.
● Excessive noise (e.g. audio system volume,
open vehicle window) will interfere with the
chime sound, and it may not be heard.
● The radar sensors may not be able to detect
and activate BSW when certain objects are
present such as:
– Pedestrians, bicycles, animals
– Several types of vehicles such as motor- cycles
– Oncoming vehicles
– Vehicles remaining in the detection zone when you accelerate from a stop
(See “BSW DRIVING SITUATIONS” later in
this section)
– A vehicle merging into an adjacent lane at a speed approximately the same as your
vehicle
(See “BSW DRIVING SITUATIONS” later in
this section) – A vehicle approaching rapidly from be-
hind.
(See “BSW DRIVING SITUATIONS” later in
this section)
– A vehicle which your vehicle overtakes rapidly.
(See “BSW DRIVING SITUATIONS” later in
this section)
● Severe weather or road spray conditions
may reduce the ability of the radar to detect
other vehicles.
● 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 adja-
cent lane. When driving in a narrow lane, the
radar sensors may detect vehicles driving
two lanes away.
● The radar sensors are designed to ignore
most stationary objects, however objects
such as guardrails, walls, foliage and parked
vehicles may occasionally be detected. This
is a normal operating condition.

Overtaking other vehicles
The BSW indicator light illuminates if you over-
take a vehicle and that vehicle stays in the
detection zone for approximately 3 seconds.
The radar sensors may not detect slower mov-
ing vehicles if they are passed quickly.If the driver activates the turn signal while
another vehicle is in the detection zone, then
the BSW indicator light flashes and a chime will
sound twice.

NOTE:
When overtaking several vehicles in a row, the
vehicles after the first vehicle may not be de-
tected if they are traveling close together.Entering from the side
The BSW indicator light illuminates if a vehicle
enters the detection zone from either side.
NOTE:
The radar sensors may not detect a vehicle
which is traveling at about the same speed as
your vehicle when it enters the detection zone.
SSD1036SSD1037
5-30Starting and driving

If the driver activates the turn signal, then the
BSW indicator light flashes and a chime will
sound twice.
NOTE:
If the driver activates the turn signal before a
vehicle enters the detection zone, the BSW indi-
cator light will flash but no chime will sound
when another vehicle is detected.
BSW temporarily not available
●When radar blockage is detected, the BSW
system will be turned off automatically, a
beep will sound and the BSW system warn- ing light (orange) will blink. The BSW system
is not available until the condition no longer
exists.
The radar sensors may be blocked by temporary
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.
Action to take:
When the above condition no longer exists, the
BSW system will resume automatically.
If the warning light (orange) continues to blink,
have the BSW system checked by an INFINITI
retailer.
BSW MALFUNCTION
When the BSW system malfunctions, they will
be turned off automatically, a beep will sound
and the BSW system warning light (orange) will
illuminate.
Action to take:
Stop the vehicle in a safe location, turn the
engine off and restart the engine.
If the warning light (orange) continues to illu-
minate, have the BSW system checked by an
INFINITI retailer.
SYSTEM MAINTENANCE
The two radar sensor unitsAfor the BSW
system are located near the rear bumper. Al-
ways keep the area near the radar sensors
clean. Do not attach stickers (including trans-
parent material), install accessories or apply
additional paint near the radar sensors. Do not
strike or damage the area around the radar
sensors. Consult an INFINITI retailer if the area
around the radar sensors is damaged due to a
collision.

PRECAUTIONS ON VEHICLE-TO-
VEHICLE DISTANCE CONTROL MODE
The system is intended to enhance the opera-
tion of the vehicle when following a vehicle
traveling in the same lane and direction.
If the distance sensor
Adetects a slower
moving 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 25% of vehicle
braking power) if necessary.
The detection range of the sensor is approxi-
mately 390 ft (120 m) ahead.
WARNING
● This system is only an aid to assist the driver
and is not a collision warning or avoidance
device. It is the driver’s responsibility to stay
alert, drive safely and be in control of the
vehicle at all times.
● The system is primarily intended for use on
straight, dry, open roads with light traffic. It
is not advisable to use the system in city
traffic or congested areas.
● This system will not adapt automatically to
road conditions. This system should be used
in evenly flowing traffic. Do not use the sys-
tem on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
The distance sensor will not detect the follow-
ing objects:
● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane
● Motorcycles traveling offset in the travel
lane
WARNING
● As there is a performance limit to the dis-
tance control function, never rely solely on
the Intelligent Cruise Control system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances in order to maintain
a safe distance between vehicles.
● If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within the
limitations of the system. The system will
cancel once it judges that the vehicle has
come to a standstill and sound a warning
chime. To prevent the vehicle from moving,
the driver must depress the brake pedal.
● The system may not detect the vehicle in
front of you in certain road or weather condi-
tions. To avoid accidents, never use the In-
telligent Cruise Control system under the
following conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
SSD0701
5-36Starting and driving

– During bad weather (rain, fog, snow, etc.)When the windshield wiper is operated at
the low speed (LO) or high speed (HI) po-
sition, the Intelligent Cruise Control sys-
tem is automatically canceled.
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed and fre-
quent braking may result in overheating
the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it difficult to keep a proper distance between vehicles
because of frequent acceleration or
deceleration
● Do not use the Intelligent Cruise Control sys-
tem if you are towing a trailer. The system
may not detect a vehicle ahead. ●
In some road or traffic conditions, a vehicle
or object can unexpectedly come into the
sensor detection zone and cause automatic
braking. You may need to control the dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the ICC system when it is not recommended
in this section.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually control the
proper following distance. The vehicle-to-
vehicle distance control mode of the Intelligent
Cruise Control (ICC) system may not be able to
maintain the selected distance between ve-
hicles (following distance) or selected vehicle
speed under some circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
Alocated on the front of the
vehicle to detect vehicles traveling ahead. The
sensor generally detects the signals returned
from the reflectors on a vehicle ahead. There-
SSD0701
Starting and driving5-37

fore, if the sensor cannot detect the reflector on
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which the
sensor cannot detect the signals:
●When the reflector of the vehicle ahead is
positioned high on the vehicle (trailer, etc.)
● When the reflector on the vehicle ahead is
missing, damaged or covered
● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When the snow or road spray from traveling
vehicles reduces the sensor’s visibility
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility
● When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The ICC system is designed to automatically
check the sensor’s operation within the limita-
tion of the system. When the sensor is covered
with dirt or is obstructed, the system will auto-
matically be canceled. If the sensor is covered
with ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them. In
these instances, the vehicle-to-vehicle distance control mode may not cancel and may not be
able to maintain the selected following distance
from the vehicle ahead. Be sure to check and
clean the sensor regularly.
The vehicle-to-vehicle distance control mode is
designed to maintain a selected distance and
reduce the speed to match the slower vehicle
ahead. The system will decelerate the vehicle as
necessary and if the vehicle ahead comes to a
stop, the vehicle decelerates to a standstill.
However, the ICC system can only apply up to
25% of the vehicles total braking power. This
system should only be used when traffic condi-
tions allow vehicle speeds to remain fairly
constant or when vehicle speeds change gradu-
ally. If a vehicle moves into the traveling lane
ahead or if a vehicle traveling ahead rapidly
decelerates, the distance between vehicles may
become closer because the ICC system cannot
decelerate the vehicle quickly enough. If this
occurs, the ICC system will sound a warning
chime and blink the system display to notify the
driver to take necessary action.
The system will cancel and a warning chime will
sound if the speed is below approximately 15
MPH (24 km/h) and a vehicle is not detected
ahead. The system will also disengage when
the vehicle goes above the maximum set speed.
See “Approach warning” later in this section.
The following items are controlled in the
vehicle-to-vehicle distance control mode:
●
When there are no vehicles traveling ahead,
the vehicle-to-vehicle distance control mode
maintains the speed set by the driver. The
set speed range is between approximately
20 and 90 MPH (32 and 144 km/h).
● When there is a vehicle traveling ahead, the
vehicle-to-vehicle distance control mode ad-
justs the speed to maintain the distance,
selected by driver, from the vehicle ahead.
The adjusting speed range is up to the set
speed. If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill within
the limitations of the system. The system
will cancel once it judges a standstill with a
warning chime.
● When the vehicle traveling ahead has moved
out from its lane of travel, the vehicle-to-
vehicle distance control mode accelerates
and maintains vehicle speed up to the set
speed.
The ICC system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead when approaching toll
gates or traffic congestion.
