The Steering Assist switch is used to turn on
and off the Steering Assist system that is
activated using the settings menu of the ve-
hicle information display.

sist” (P. 5-73).WARNING
• The front sonar system is a convenience
but it is not a substitute for proper
driving.
• The rear sonar system is a convenience
but it is not a substitute for proper back-
ing. Always turn and check that it is safe
to do so before backing up. Always back
up slowly. The front sonar system:
• is active when the ignition switch is in the
ON position and the shift lever is in a for-
ward gear position.
• a beeping tone is emitted when the sensors detect obstacles within 3 ft (1.0 m) of the
front bumper.
The rear sonar system:
• is active when the ignition is in the ON position and the shift lever is in R (Reverse).
• a beeping tone is emitted when the sensors detect obstacles within 4.9 ft (1.5 m) of the
rear bumper.
The front and rear sonar system may be en-
abled by pushing the front and rear sonar
switch. Push the switch again to disable the
system.
The system will automatically reset the next
time the ignition switch is turned on.
For additional information, see “Front and
rear sonar system” (P. 5-147).

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 OPERATION
1. LDP indicator
2. Lower display buttons3. ProPILOT Assist switch
4. LDP ON indicatorThe 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 ProPI-
LOT Assist switch on the steering wheel af-
ter starting the engine. The LDP ON indicator
on the instrument panel will illuminate. Push
the ProPILOT Assist switch on the steering
wheel again to turn off the LDP system. The
LDP ON indicator will turn off.
