WARNING
The TSR system is only intended to be a
support device to help provide the driver
with information. It is not a replacement
for the driver’s attention to traffic condi-
tions or responsibility to drive safely. It
cannot prevent accidents due to careless-
ness. It is the driver’s responsibility to stay
alert and drive safely at all times.
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.
LSD3330LSD3378

– When rain, snow or dirt adheres tothe 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.)
– 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.

SYSTEM MAINTENANCE
The TSR system uses the same multi-sensing
front camera unit that is used by the Lane
Departure Warning (LDW) system, located in
front of the interior rearview mirror. For ad-
ditional information, see ”System mainte-
nance” (P. 5-38).
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 driv-
ing lane. For additional information, see
“LDW system operation” (P. 5-35).

LANE DEPARTURE WARNING (LDW)
5-34Starting and driving

LDW SYSTEM OPERATION
The LDW system provides a lane departure
warning function when the vehicle is driven at
speeds of approximately 37 mph (60 km/h)
and above and the lane markings are clear.
When the vehicle approaches either the left
or the right side of the traveling lane, the
steering wheel will vibrate and the LDW indi-
cator on the instrument panel will blink to
alert the driver.
The warning function will stop when the ve-
hicle returns inside of the lane markers.

LDW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDW system. Failure to follow the
warnings and instructions for proper use of
the LDW system could result in serious in-
jury 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 system will not operate at speeds
below approximately 37 mph (60 km/h)
or if it cannot detect lane markers.

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 must be turned on with the
ProPILOT Assist switch on the steering
wheel, every time the ignition is placed in the
ON position.
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 when the
vehicle has left the center of the traveling
lane with an indicator and 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 left or right
wheels individually (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.

LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDP system. Failure to follow the
warnings and instructions for proper use of
the LDP system could result in serious in-
jury or death.
• The LDP system may activate if you
change lanes without first activating
your turn signal or, for example, if a con-
struction zone directs traffic to cross an
existing lane marker. If this occurs you
may need to apply corrective steering to
complete your lane change.
• Because the LDP may not activate under
the road, weather, and lane marker con-
ditions described in this section, it may
not activate every time your vehicle be-
gins to leave its lane and you will need to
apply corrective steering.
• The LDP system will not operate at
speeds below approximately 37 mph (60
km/h) or if it cannot detect lane markers.
• When the LDP system is operating,
avoid excessive or sudden steering ma-
neuvers. Otherwise, you could lose con-
trol of the vehicle. •
Do not use the LDP system under the
following conditions as it may not func-
tion properly:
– During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such
as on ice or snow.
– When driving on winding or uneven
roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshift or tem-
porary lane.
– When driving on roads where the lane
width is too narrow.
– When driving without 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 brake parts or suspen-
sion parts.
• The system may not function properly
under the following conditions: – On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-
standard lane markers; or lane mark-
ers 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 shad-
ows, snow, water, wheel ruts, seams
or lines remaining after road repairs.
(The LDP system could detect these
items as lane markers.)
– On roads where the traveling lane merges or separates.
– When the vehicle’s traveling direc- tion does not align with the lane
marker.
– When traveling close to the vehicle in front of you, which obstructs the lane
camera unit detection range.
– When rain, snow or dirt 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.
