to the side of the road at a safe place
and allow the transmission to return to
normal operation; or have it repaired if
necessary.

VEHICLE SECURITY SYSTEM

NOTE:
• Once activated, your heated steeringwheel will automatically turn on and
off to maintain a temperature above
68°F (20°C).
• When the temperature of the steering wheel is above 122°F (50°C) and the
heated steering wheel switch is turned
on, the system will not heat the steer-
ing wheel. This does not indicate a
malfunction.
The Steering Assist switch is used to en-
able and disable the Steering Assist sys-
tem that is activated using the settings
menu of the vehicle information display.
The Steering Assist system controls the
steering system, when ProPILOT Assist is
engaged, to help keep your vehicle near
the center of the lane when driving. For
additional information, see ”ProPILOT As-
sist” (P. 5-94) and “Intelligent Lane Interven-
tion (I-LI)” (P. 5-40).

• Do not place reflective materials, such aswhite 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. If the camera unit is
damaged due to an accident, it is recom-
mended that you visit a NISSAN dealer.
WARNING
Failure to follow the warnings and in-
structions for proper use of the I-LI sys-
tem could result in serious injury or
death.
• The I-LI system will not steer the ve-
hicle or 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 I-LI system is primarily intended
for use on well-developed freeways
or highways. It may not detect the
lane markers in certain road,
weather, or driving conditions.
The I-LI system must be turned on with the
ProPILOT Assist switch (for vehicles with
ProPILOT Assist) on the steering wheel, ev-
ery time the ignition is placed in the ON
position.
The I-LI system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The I-LI system warns the driver when the
vehicle has lef t the center of the traveling
lane with an indicator and a steering wheel
vibration. The system helps assist the
driver to return the vehicle to the center of
the traveling lane by applying the brakes to
the lef t or right wheels individually (for a
short period of time).
The I-LI system monitors the lane markers
on the traveling lane using the camera unit
OAlocated above the inside mirror.

approaches either the lef t or the right side
of the traveling lane, the steering wheel will
vibrate and the LDW indicator (orange) on
the instrument panel will blink to alert the
driver. Then, the I-LI system will automati-
cally apply the brakes for a short period of
time to help assist the driver to return the
vehicle to the center of the traveling lane.
To turn on the I-LI system, push the ProPI-
LOT Assist switch (for vehicles with ProPI-
LOT Assist) on the steering wheel af ter
starting the engine/motor. The I-LI indica-
tor on the instrument panel will illuminate.
Push the ProPILOT Assist switch again to
