SYSTEM OPERATION
The Traffic Sign Recognition (TSR) system
displays the following types of road signs:
OASpeed sign detected (in Canada)
OBSpeed sign detected (in USA)
OCSpeed sign detected (no speed limit
detected)
OD“Do not pass” sign detected
CAUTION
• The TSR system is intended as an aid to
careful driving. It is the driver’s responsi-
bility to stay alert, drive safely, and ob-
serve all road regulations that currently
apply, including looking out for road
signs. •
The TSR system may not function prop-
erly under the following conditions:
– When the road sign is not clearly vis-
ible, for example, due to damage or
weather conditions.
– When rain, snow or dirt adheres to
the windshield in front of the multi-
sensing camera unit.
– When the headlights are not bright,
for example, due to dirt on the lens or
if the aiming is not adjusted properly.
– When strong light enters the camera
unit. (For example, the light directly
shines on the front of the vehicle at
sunrise or sunset.)
– When a sudden change in brightness
occurs. (For example, when the ve-
hicle enters or exits a tunnel or under
a bridge.)
– In areas not covered by the naviga-
tion system.
– If there are deviations in relation to
the navigation, for example due to
changes in the road routing.
– When overtaking buses or trucks
with speed stickers.

TSR system may be deactivated automati-
cally. The “Not Available: High Camera
Temp.” warning message will appear in the
vehicle information display.
Action to take:
When the interior temperature is reduced,
the TSR system will resume operating
automatically.
SYSTEM MALFUNCTION
If the TSR system malfunctions, it will be
turned off automatically and the system
“Malfunction” warning message will appear
in the vehicle information display.
Action to take:
If the TSR “Malfunction” message appears,

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the LDW system
could result in serious injury or death.
• This system is only a warning device to
inform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or prevent loss of control. It is
the driver’s responsibility to stay alert,
drive safely, keep the vehicle in the trav-
eling lane, and be in control of the vehicle
at all times. The LDW 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 LDW system monitors the lane markers
on the traveling lane using the camera unit
O1
located above the inside mirror.
The LDW system warns the driver with an
indicator in the vehicle information display
and the steering wheel will vibrate, indicating
that the vehicle is beginning to leave the
driving lane. For additional information, see
“LDW system operation” (P. 5-36).

SYSTEM TEMPORARILY
UNAVAILABLE
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F [40°C]) and then started, the
LDW system may be deactivated automati-
cally and the following message will appear
in the vehicle information display: “Not avail-
able: High Camera Temp.”
When the interior temperature is reduced,
the LDW system will resume operating
automatically.
The LDW system is not designed to warn
under the following conditions:
• When you operate the lane change signaland change traveling lanes in the direction
of the signal. (The LDW system will become
operable again approximately 2 seconds
after the lane change signal is turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDW functions will resume.
SYSTEM MALFUNCTION
If the LDW system malfunctions, it will cancel
automatically and “Malfunction” will appear
in the vehicle information display. If “Mal-
function” appears in vehicle information dis-
play, pull off the road to a safe location and
stop the vehicle. Place the shift position in the
P (Park) position and ignition switch in the
OFF position and restart the engine. If “Mal-
function” continues to appear in vehicle infor-
mation display, have the system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
SYSTEM MAINTENANCE
The lane camera unitO1for the LDW system
is located above the inside mirror. To keep the
proper operation of the LDW system and
prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the camera unit.

• Do not place reflective materials, such aswhite paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely 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 recommended that
you visit an INFINITI retailer.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the LDP system
could result in serious injury or death.
• The LDP system will not steer the vehicle
or prevent loss of control. It is the driv-
er’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 is primarily intended for
use on well-developed freeways or high-
ways. It may not detect the lane markers
in certain road, weather, or driving
conditions.
The LDP 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 LDP system warns the driver with a
warning indicator in the vehicle information
display, the steering wheel will vibrate and
helps assist the driver to return the vehicle to
the center of the traveling lane by applying
the brakes to the left or right wheels individu-
ally (for a short period of time).
The LDP system monitors the lane markers
on the traveling lane using the camera unit
O1
located above the inside mirror.
