WARNING
When this switch is activated the following
systems (if so equipped) are turned off and
will not work.
∙ Distance Control Assist (DCA)
∙ Blind Spot Intervention (BSI)
∙ Lane Departure Prevention (LDP)
The dynamic driver assistance switch is used
to turn on and off the following systems (Dis-
tance Control Assist (DCA) , Blind Spot Inter-
vention® (BSI), and Lane Departure Preven-
tion (LDP)) that are activated (if so equipped)
using the settings menu in the lower display. When the dynamic driver assistance switch is
turned off, the indicator on the switch is off.
The indicator will also be off if the system is
deactivated using the settings menu.
The DCA system brakes and moves the ac-
celerator pedal upward according to the dis-
tance from and the relative speed of the ve-
hicle ahead to help assist the driver in
maintaining a following distance. For addi-
tional information, refer to “Distance Control
Assist (DCA)” in the “Starting and driving”
section of this manual.
The BSI system helps alert the driver of other
vehicles in adjacent lanes when changing
lanes, and helps assist the driver to return the
vehicles to the center of the traveling lane.
For additional information, refer to “Blind
Spot Intervention® (BSI)” in the “Starting and
driving” section of this manual.
The LDP system warns the driver with a
warning indicator in the vehicle information
display and a steering wheel vibration, 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). For additional
information, refer to “Lane Departure Pre-
vention (LDP)” in the “Starting and driving”
section of this manual

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 toinform the driver of a potential unin-

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.

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 vehicleor 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 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
1
located above the inside mirror.

3. Dynamic driver assistance switch (forvehicles without ProPILOT Assist)
4. ProPILOT Assist switch (for vehicles with ProPILOT Assist)
LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 37 mph (60 km/h). When the vehicle
approaches either the left or the right side of
the traveling lane, the steering wheel will vi-
brate and the LDP indicator (orange) on the
instrument panel will blink to alert the driver.
Then, the LDP system will automatically ap-
ply 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 LDP system, push the dynamic
driver assistance switch (for vehicles without
ProPILOT Assist) or the ProPILOT Assist
switch (for vehicles with ProPILOT Assist) on
the steering wheel after starting the engine.
The LDP indicator (green) on the instrument
panel will illuminate. Push the dynamic driver
assistance switch (for vehicles without Pro-
PILOT Assist) or the ProPILOT Assist switch
(for vehicles with ProPILOT Assist) on the
steering wheel again to turn off the LDP
system. The LDP indicator will turn off.

rarily by pushing the dynamic driver assis-
tance switch (for vehicles without ProPILOT
Assist) or the ProPILOT Assist switch (for
vehicles with ProPILOT Assist) on the steer-
ing wheel.

5-40Starting and driving

∙ When the headlights are not bright dueto 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 sun-
rise or sunset.)
∙ When a sudden change in brightness oc- curs. (For example, when the vehicle en-
ters or exits a tunnel or under a bridge.)
While the LDP system is operating, you may
hear a sound of brake operation. This is nor-
mal and indicates that the LDP system is
operating properly.
SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the LDP
system are not designed to work under the
following conditions: ∙ When you operate the lane change signal and change the traveling lanes in the di-
rection of the signal. (The LDP system will
be deactivated for approximately 2 sec-
onds 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 warning and assist functions will
resume.
Condition B:
The assist function of the LDP system is not
designed to work under the following condi-
tions (warning is still functional): ∙ When the brake pedal is depressed.
∙ When the steering wheel is turned as far as necessary for the vehicle to change
lanes.
∙ When the vehicle is accelerated during LDP system operation.
∙ When the Intelligent Cruise Control (ICC) approach warning occurs.
∙ When the hazard warning flashers are operated.
∙ When driving on a curve at high speed.
After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDP system application of the
brakes will resume. Condition C:
If the following messages appear in the ve-
hicle information display the LDP system will
be turned off automatically:
∙ “Not Available Poor Road Conditions”: When the VDC system (except Traction
Control System [TCS] function) or ABS
operates.
∙ “Currently not available”: When the VDC system is turned off.
Action to take:
When the above conditions no longer exist,
turn off the LDP system. Push the dynamic
driver assistance switch (for vehicles without
ProPILOT Assist) or the ProPILOT Assist
switch (for vehicles with ProPILOT Assist) on
the steering wheel again to turn the LDP
system back on.
Temporary disabled status at high temperature:
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F [40°C]) and then the LDP sys-
tem is turned on, the LDP system may be de-
activated automatically and the following
message will appear on the vehicle information
display: “Not available: High Camera Temp.”
