ACTIVE LANE CONTROL OP-
ERATION
Active Lane Control slightly corrects front
tire angles and steering wheel torque to help
reduce the difference between the vehicle’s
direction and the lane direction
which is
detected by using the camera unitlocated
above the inside mirror.
Active Lane Control operates under the
following conditions:
. When the vehicle is driven at speeds of
approximately 45 MPH (70 km/h) and
above.
. When the Lane Departure Prevention
(LDP) system is enabled in the settings menu on the lower display. To turn on
the LDP system, see “Lane Departure
Warning (LDW)/Lane Departure Pre-
vention (LDP)” (P.5-34).
. When Active Lane Control is enabled in

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.
Starting and driving5-31

5-32Starting and driving
— 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
.
Action to take:
When the interior temperature is reduced,
push the dynamic driver assistance switch
again to turn Active Lane Control back on.
SYSTEM MALFUNCTION
If Active Lane Control malfunctions, it will
cancel automatically. The chassis control
warning will appear in the vehicle informa-
tion display.

Action to take:
If the chassis control warning appears, pull
off the road to a safe location and stop the
vehicle. Turn the engine off and restart the
engine. If the chassis control warning con-
tinues to illuminate, have the system
checked. It is recommended you visit an
INFINITI retailer for this service.

SYSTEM MAINTENANCE
The lane camera unitfor 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
chime that the vehicle is beginning to
leave the driving lane.
. Lane Departure Prevention (LDP) system
— warns the driver with an indicator in the vehicle information display and
chime, and helps the driver to return
the vehicle to the center of the
traveling lane.
JVS1124X
The LDW and LDP systems use a camerainstalled behind the windshield to monitor
the lane markers of your traveling lane.
