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.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.

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- 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 trunk of your vehicle
● When your vehicle is towing a trailer, etc.
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 obstructs, the system will automati-
cally 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 con- trol 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 falls 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.

– When rain, snow or dirt adhere to the sys-tem sensor
– On steep downhill roads (frequent brak- ing may result in overheating the brakes)
– On repeated uphill and downhill roads
– When towing a trailer or other vehicle
● 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 DCA system when it is not recommended
in this section.
DISTANCE CONTROL ASSIST
OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually decelerate to
maintain the proper following distance. The
Distance Control Assist (DCA) system may not
be able to decelerate the vehicle under some
circumstances.
The DCA system uses a sensor
Alocated on
the front of the vehicle to detect vehicles trav-
eling ahead. The sensor generally detects the
signals returned from the reflectors on a vehicle
ahead. Therefore, if the sensor cannot detect
the reflector on the vehicle ahead, the DCA
system may not operate. 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 DCA system is designed to automatically
check the sensor’s operation. When the sensor
is covered with dirt or is obstructed, the system
will automatically be canceled. If the sensor is
covered with ice, a transparent or translucent
vinyl bag, etc., the DCA system may not detect
them. In these instances, the Distance Control
Assist (DCA) system may not be able to decel-
erate the vehicle properly. Be sure to check and
clean the sensor regularly.

5-64Starting and driving

The FCW system uses the distance sensorA
located below the front bumper to measure the
distance to the vehicle ahead. When the system
judges that your vehicle is getting close to the
vehicle ahead in the travel lane, the vehicle
ahead detection indicator blinks and a warning
chime sounds.
PRECAUTIONS ON FCW SYSTEM
WARNING
●The FCW system is intended to warn you be-
fore a collision but will not avoid a collision.
It is the driver’s responsibility to stay alert,
drive safely and be in control of the vehicle at
all times.
● As there is a performance limit, the system
may not provide a warning in certain
conditions.
● The system will not detect the following
objects:
– Pedestrians, animals or obstacles in the roadway
– Oncoming vehicles in the same lane
● The system will not detect another vehicle
under the following conditions: – When the sensor gets dirty and it is im-
possible to detect the distance from the
vehicle ahead.
– When driving into a strong light (i.e., sunlight)
● The sensor generally detects the signals re-
turned from the reflectors on a vehicle
ahead. Therefore, the system may not func-
tion properly under the following conditions:
– When the reflectors of the vehicle ahead are positioned high or close to each other
(including a small vehicle such as
motorcycles).
– When the sensor gets dirty or it is impos- sible to detect the distance from the ve-
hicle ahead.
– When the reflectors on the vehicle ahead are missing, damaged or covered.
– When the reflectors of the vehicle ahead are covered with dirt, snow or road spray.
– When visibility is low (such as rain, fog, snow, etc.).
– When snow or road spray from traveling vehicles is splashed. – When dense exhaust or other smoke
(black smoke) from vehicles reduces the
visibility of the sensor.
– When excessively heavy baggage is loaded in the rear seat or the luggage
room of your vehicle.
– When abruptly accelerating or decelerating.
– On a steep downhill slope or on roads with sharp curves.
– When there is a highly reflective object near the vehicle ahead (i.e., being very
close to another vehicle, signboard, etc.)
– When you are towing a trailer.
● Depending on certain road conditions
(curved or beginning of a curve), vehicle con-
ditions (steering position or vehicle posi-
tion), or the preceding vehicle’s conditions
(position in lane, etc.), the system may not
function properly. The system may detect
highly reflective objects such as reflectors,
signs, white markers, and other stationary
objects on the road or near the traveling lane
and provide unnecessary warning.
● The system may not function in offset
conditions.

WARNING
●If the low tire pressure warning light illumi-
nates or LOW PRESSURE information is dis-
played on the monitor screen 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 fail-
ure. Serious vehicle damage could occur and
may lead to an accident and could result in
serious personal injury. Check the tire pres-
sure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure
shown on the Tire and Loading Information
label to turn the low tire pressure warning
light OFF. If the light still illuminates 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.
● 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.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the selector lever to
the P (Park) position.
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from
traffic and clear of the vehicle.
WARNING
●Make sure the parking brake is securely ap-
plied and the automatic transmission is in
the P (Park) position.
● Never change tires when the vehicle is on a
slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for professional
road assistance.
In case of emergency6-3

When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking the
tires, make sure no wheel nuts are missing, and
check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires should be rotated every
7,500 miles (12,000 km).
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If nec-
essary, adjust the pressure in all tires, includ-
ing the spare, to the pressure specified. Check
carefully for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS) trans-
mitter components: Replace the TPMS transmit-
ter grommet seal, valve core and cap when the
tires are replaced due to wear or age.
Tire, wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment. If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Accelerator pedal: Check the pedal for smooth
operation and make sure the pedal does not
catch or require uneven effort. Keep the floor
mat away from the pedal.
Automatic transmission P (Park) mechanism: On
a fairly steep hill, check that your vehicle is held
securely with the selector lever in the P (Park)
position without applying any brakes. Brake pedal:
Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down
further than normal, the pedal feels spongy or
the vehicle seems to take longer to stop, see an
INFINITI retailer immediately. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely
held on a fairly steep hill with only the parking
brake applied. If the parking brake needs ad-
justed, see an INFINITI retailer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints/headrests move up and down
smoothly and that the locks (if so equipped)
hold securely in all latched positions.
Steering wheel: Check for changes in the steer-
ing conditions, such as excessive free play,
hard steering or strange noises.
