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
detect and activate BSW when certain
objects are present such as: – Pedestrians, bicycles, or animals.
NSD626
5-40Starting and driving

–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 that is too close to your
vehicle.
– A vehicle approaching rapidly from
behind.
– A vehicle which your vehicle over-
takes rapidly.
•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
adjacent 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 operating
condition.
•The following conditions may reduce the
ability of the radar to detect other ve-
hicles: – 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
sensors. These conditions may reduce
the ability of the radar to detect other
vehicles.
•Do not use the BSW system when tow-
ing a trailer because the system may not
function properly.
•Excessive noise (e.g. audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.
•The BSW system may not provide a
warning for vehicles that pass through
the detection zone quickly.
Another vehicle approaching from
behind
Illustration 1: The BSW indicator light illumi-
nates if a vehicle enters the detection zone
from behind in an adjacent lane.
However, if the overtaking vehicle is travel-
ling much faster than your vehicle, the indica-
tor light may not illuminate before the de-
tected vehicle is beside your vehicle. 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.

system are located near the rear bumper.
Always keep the area near the radar sensors
clean.
The radar 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 radar sensors.
Check for and remove objects obstructing
the area around the radar sensors.
Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors. Do not strike or damage the area around the
radar sensors. It is recommended you consult
an INFINITI retailer if the area around the

Rules. Operation is subject to the following
two conditions: (1) This device may not
cause harmful interference, and (2) this de-
vice must accept any interference received,
including interference that may cause unde-
sired operation.
NOTE
Changes or modification not expressly ap-
proved by the party responsible for compli-
ance could void the user’s authority to oper-
ate the equipment.
For Canada:
This device complies with Industry Canada
license-exempt RSS standard(s). Operation
is subject to the following two conditions: (1)
this device may not cause harmful interfer-
ence, and (2) this device must accept any
interference received, including interference
that may cause undesired operation of the
device.Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. You must
select a lower gear in good time on long and
steep downhill gradients, especially if the ve-
hicle is laden or towing a trailer.WARNING
For vehicles with automatic transmission,
you need to have selected manual drive
program M (see "Manual drive program"
earlier in this section). By doing so, you will
make use of the braking effect of the en-
gine. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Use cruise control only if road and traffic
conditions are appropriate for maintaining a
steady speed for a prolonged period. You can
set the cruise control at any road speed
above 20 MPH (30 km/h).
The speed indicated in the speedometer may
differ slightly from the set speed.

How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
To increase the distance to the vehicle ahead,
turn the knob
3toward the rear2.To
decrease the distance to the vehicle ahead,
turn the knob
3toward the front1.
You can see this distance in the vehicle infor-
mation display.
The distance to the vehicle ahead will change
according to the vehicle speed. The higher the
vehicle speed, the longer the distance.
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 distance
warning light. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
•The chime sounds.
•The distance warning light is illuminated.
The warning chime may not sound and the
distance warning light may not illuminate 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 ve-
hicles is not changing. In this case, the
distance warning light will be on.
•When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing.
•When a vehicle cuts in near your vehicle
•The warning chime will not sound and the
distance warning light will not illuminate
when: – The vehicle approaches other vehicles that are parked or moving slowly. – The accelerator pedal is depressed,
overriding the system.
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 and the message [ICC off] is
displayed in the vehicle information display
for 5 seconds under the following conditions
and the control is automatically canceled.
•The electric parking brake is applied.
•The VDC intervenes or the VDC is deacti-
vated.
•The P (Park), R (Reverse) or N (Neutral)
position is engaged.
•The cruise control lever is pulled in order to
pull away but the front passenger door or
one of the rear doors is open.
•The vehicle is skidding or a wheel slips.
•Active Park Assist is activated.

ICC LIMITATIONS
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
•This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’s re-
sponsibility 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 sys-
tem in city traffic or congested areas.
•This system will not adapt automati-
cally to road conditions. This system
should be used in evenly flowing traffic.
Do not use the system on roads with
sharp curves, or on icy roads, in heavy
rain or in fog.
•As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive or
absent-minded driving, or overcome poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween vehicles.
•If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. Once the
vehicle is stationary, it remains station-
ary and you do not need to depress the
brake pedal.
•Always pay attention to the operation
of the vehicle and be ready to manually
control the proper following distance.
The ICC system may not be able to main-
tain the selected distance between ve-
hicles (following distance) or selected
vehicle speed under some circum-
stances.
•Normally when controlling the distance
to a vehicle ahead, this system auto-
matically accelerates or decelerates
your vehicle according to the speed of
the vehicle ahead. If required, depress
the accelerator to properly accelerate
your vehicle when acceleration is re-
quired for a lane change. Depress the
brake pedal when deceleration is re- quired to maintain a safe distance to the
vehicle ahead due to its sudden braking
or if a vehicle cuts in. Always stay alert
when using the ICC system.
•The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never
use the ICC 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.
– During bad weather (rain, fog, snow,
etc.).
– When rain, snow or dirt adhere to the
system sensor.
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes).
– On repeated uphill and downhill
roads.
– When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration.
– If there is interference by other radar
sources.
