ACTIVE LANE CONTROL LIM-
ITATIONS

WARNING

Listed below are the limitations for
Active Lane Control. Failure to operate
the vehicle in accordance with these
limitations could result in serious injury
or death.

.

Active Lane Control is primarily in-
tended for use on well-developed
freeways or highways. It may not
detect the lane markers for certain
roads, weather or driving conditions.

.

Using Active Lane Control under
some conditions of road, lane marker
or weather, or if you attempt to
change lanes without using the lane
change signal could lead to an un-
expected system operation. In such
conditions, you need to correct the
vehicle’s direction with your steering
operation to avoid accidents.

.

Active Lane Control will not operate
at speeds below approximately 45

MPH (70 km/h) or if it cannot detect
lane markers.

.

Active Lane Control may not operate
properly and should not be used
under the following conditions:

— During bad weather (rain, fog,

snow, etc.).

— When driving on slippery roads,

such as on ice or snow, etc.

— When driving on winding or un-

even roads.

— When there is a lane closure due

to road repairs.

— When driving in a makeshift lane.

— When driving on roads where the

lane width is too narrow.

— When driving with a tire that is

not within normal tire conditions
(for example, tire wear, low tire
pressure, installation of spare tire,
tire chains, non-standard wheels).

— When the vehicle is equipped with

non-original steering parts or sus-
pension parts.

.

Active Lane Control may or may not
operate properly under the following
conditions:

— On roads where there are multi-

ple parallel lane markers; lane
markers that are faded or not
painted clearly; yellow painted
lane markers; non-standard lane
markers; or lane markers covered
with water, dirt, snow, etc.

— On roads where discontinued lane

markers are still detectable.

— On roads where there are sharp

curves.

— On roads where there are sharply

contrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs. (Active Lane Control
could detect these items as lane
markers.)

— On roads where the traveling lane

merges or separates.

— When the vehicle’s traveling di-

rection does not align with the
lane marker.

— When traveling close to the ve-

hicle in front of you, which ob-
structs the lane camera unit
detection range.

— When rain, snow, dirt or object

adheres to the windshield in front

of the lane camera unit.

— When the headlights are not

bright due to dirt on the lens or
if the aiming is not adjusted
properly.

— When strong light enters the lane

camera unit. (For example, the
light directly shines on the front
of the vehicle at sunrise or sun-
set.)

— When a sudden change in bright-

ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)

— When entering or exiting toll-

gates.

— When driving on roads with a

widening or narrowing lane width.

SYSTEM TEMPORARILY UNA-
VAILABLE

Automatic deactivation

Active Lane Control is not designed to
operate under the following conditions:

.

When the Vehicle Dynamic Control

(VDC) system (except TCS function) or
ABS operates.

.

When you operate the lane change signal

and change the traveling lanes in the
direction of the signal. (Active Lane
Control is deactivated for approximately
2 seconds after the lane change signal is

turned off.)

.

When the vehicle speed lowers to less

than approximately 45 MPH (70 km/h).

.

When the hazard warning flashers are

operated.

After the above conditions have finished and
the operating conditions are satisfied again,
Active Lane Control will resume operation.

Temporary disabled status at high
temperature

If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F (40°C)) and then Ac-
tive Lane Control is turned on, Active Lane
Control may be deactivated automatically.
The high cabin temperature message will
appear in the vehicle information display

.

SYSTEM MAINTENANCE

The lane camera unit

for Active Lane

Control is located above the inside mirror. To
keep the proper operation of Active Lane
Control and prevent a system malfunction,
be sure to observe the following:

.

Always keep the windshield clean.

.

Do not attach a sticker (including trans-

parent material) or install an accessory
near the camera unit.

.

Do not place reflective materials, such as

white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.

.

Do not strike or damage the areas around

the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit. It is recommended
you contact an INFINITI retailer if the
camera unit is damaged due to an
accident.

WARNING

Failure to follow the warnings and
instructions for proper use of the LDW
and LDP systems could result in serious
personal injury or death.

.

The LDW and LDP systems will not
prevent loss of control. It is the
driver’s responsibility to stay alert,
drive safely, keep the vehicle in the
traveling lane, and be in control of
the vehicle at all times.

.

The LDP system may activate if you
change lanes without first activating
your turn signal or, for example, if a
construction zone directs traffic to
cross an existing lane marker. If this
occurs, you may need to apply cor-
rective steering to complete your lane
change.

.

Because the LDP system may not
activate under the road, weather,
and lane marker conditions described
in this section, it may not activate
every time your vehicle begins to
leave its lane and you will need to
apply corrective steering.

.

Lane Departure Warning (LDW) system

— warns the driver with an indicator in

the vehicle information display and
vibrations of the steering wheel that
the vehicle is beginning to leave the
driving lane.

.

Lane Departure Prevention (LDP) system

(if so equipped)
— warns the driver with an indicator in

the vehicle information display and
vibrations of the steering wheel, and
helps the driver to return the vehicle
to the center of the traveling lane.

JVS1124X

WARNING

Failure to follow the warnings and
instructions for proper use of the BSW
system could result in serious injury or
death.

.

The BSW system is not a replacement
for proper driving procedure and is
not designed to prevent contact with
vehicles or objects. When changing
lanes, 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.
Never rely solely on the BSW system.

.

There is a limitation to the detection
capability of the radar. Not every
moving object or vehicle will be
detected. Using the BSW system
under some road, ground, lane mar-
ker, traffic or weather conditions
could lead to improper system opera-
tion. Always rely on your own opera-
tion to avoid accidents.

The BSW system helps alert the driver of
other vehicles in adjacent lanes when chan-
ging lanes.

JVS1122X

The BSW system uses radar sensors
installed near the rear bumper to detect
other vehicles in an adjacent lane.

BLIND SPOT WARNING (BSW) (if
so equipped)

SSD1030

Detection zone

The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion zone shown as illustrated. This detec-
tion 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.

If the radar sensors detect a vehicle in the
detection zone, the side indicator light
illuminates.
If the turn signal is then activated, the
system chimes (twice) and the side indicator
light flashes. The side indicator light con-
tinues to flash until the detected vehicle
leaves the detection zone.

NOTE:

.

The side indicator lights illuminate for a

few seconds when the ignition switch is
placed in the ON position.

.

The brightness of the side indicator

lights is adjusted automatically depend-
ing on the brightness of the ambient
light.

.

If a vehicle comes into the detection zone

after the driver activates the turn
signal, then only the side indicator light
flashes and no chime sounds. (See “BSW
driving situations” (P.5-43).)

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
vehicles under all conditions.

.

The radar sensors may not be able to
detect and activate BSW when cer-
tain objects are present such as:

— Pedestrians, bicycles, animals.

— Vehicles such as motorcycles, low

height vehicles, or high ground
clearance vehicles.

— Oncoming vehicles.

— Vehicles remaining in the detec-

tion zone when you accelerate
from a stop.

— A vehicle merging into an adja-

cent lane at a speed approxi-
mately the same as your vehicle.

— A vehicle approaching rapidly

from behind.

— A vehicle which your vehicle over-

takes rapidly.

— A vehicle that passes through the

detection zone quickly.

.

The radar sensor’s detection zone is
designed 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 vehicles driving
two lanes away.

.

The radar sensors are designed to
ignore most stationary objects, how-
ever objects such as guardrails, walls,
foliage and parked vehicles may oc-
casionally be detected. 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/snow build-up on the

vehicle

— Dirt build-up on the vehicle

.

Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar to
detect other vehicles.

.

Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.
