■How to activate the system1Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
When the MAIN button is pressed, both ACC with
LSF and the Lane Keeping Assist System (LKAS) are
either turned on or off.
ACC with LSF may not work properly under certain
conditions. 2 ACC with LSF Conditions and Limitations
P. 461
When not using ACC with LSF: Turn off adaptive
cruise by pressing the MAIN button. This also will
turn off the Lane Keeping Assist System (LKAS).
Do not use ACC with LSF under the following
conditions:
•On roads with heavy traf fic or while driving in
continuous stop and go traffic.
•On roads with sharp turns.
•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC with LSF will not apply the brakes to
maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
How to use
■Press the MAIN button on
the steering wheel.
ACC (green) is on in the instrument panel.
ACC with LSF is ready to use.

Driving
When driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press down the RES/+/SET/– switch when you reach the desired speed.
The moment you release the switch, the set speed is fixed, and ACC with LSF begins.
When driving slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pressing the switch fixes your set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If your vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.
When ACC with LSF starts operating, the
vehicle icon, interval bars and set speed
appear on the multi-information display.
When you use ACC with LSF, Straight Driving
Assist (a feature of the Electric Power Steering
system) is activated.
By enabling the steering system to
automatically compensate for natural steering
pull, Straight Driving Assist makes it easier for
you to keep your vehicle in a straight line.

Increase or decrease the vehicle speed using the RES/+/SET/– switch on the steering
wheel.
• Each time you press the switch up or do wn, the vehicle speed is increased or
decreased by about 1 mph or 1 km/h accordingly.
• If you keep pressing the switch up or down, the vehicle speed increases or
decreases by about 5 mph or 5 km/h accordingly.
■To Adjust the Vehicle Speed1 To Adjust the Vehicle Speed
If a vehicle detected ahead is going at a speed slower
than your increased set speed, ACC with LSF may not
accelerate your vehicle. This is to maintain the set
interval between your vehi cle and the vehicle ahead.
When you depress the accelerator pedal and then
press down and release the RES/+/SET/– switch, the
current speed of the vehicle is set.

■Automatic cancellation
The beeper sounds and a message appears on the multi-information display when
ACC with LSF is automatically canceled. An y of these conditions may cause the ACC
with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor behind the emblem gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC with LSF range is too close to your
vehicle.
• When a detected vehicle goes out of th e ACC with LSF range while your vehicle
is stationary.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• When the Maximum Load Limit is exceeded.
• When passing through an enclosed space, such as tunnel.
The ACC with LSF automatic cancellation can be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicl e is stationary.
• The vehicle stops for mo re than 10 minutes.
• The engine is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically
canceled, you can still resu me the prior set speed.
Wait until the condition that caused ACC with LSF to
cancel improves, then press the RES/+/SET/– switch
down.

Driving
Lane Keeping Assist System (LKAS)
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides tactile and visual al erts if the vehicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicl e control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 97
Do not place objects on the instrument panel.
Objects may reflect on th e windshield and prevent
correct detection of the traffic lanes.
The LKAS only alerts you when lane drift is detected
without a turn signal in us e. The LKAS may not detect
all lane markings or lane departures; accuracy will
vary based on weather, speed, and lane marker
condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions:
2 LKAS Conditions and Limitations P. 476
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 483
When you operate the turn signals to chan ge lanes, the system is suspended, and
resumes after the signals are off.
If you make a lane change without operating the turn signals, the LKAS alerts
activate, and torque is applied to the steering.
■Front Sensor Camera
Monitors the lane
lines.■Tactile and visual alerts
Rapid vibrations on the steering
wheel and a warning display alert
you that the vehicle is drifting out of
a detected lane.
■Steering input assist
The system applies torque to the steering to keep the vehicle between the left and
right lane lines. The applied torque become s stronger as the vehicle gets closer to
either of the lane lines.

Driving
Provides assistance to keep the vehicle in the center of the lane. When the vehicle
nears a white or yellow line, steering force of the electric power steering will become
stronger.
When the vehicle enters the warning area, the LKAS alerts you with slight steering
wheel vibration as well as a warning display.
■Lane Keep Support Function1 Lane Keeping Assist System (LKAS)
The LKAS may not function as designed while driving
in frequent stop and go traf fic, or on roads with
sharp curves.
When it fails to detect lanes, the system will
temporarily be canceled. When a lane is detected, the
system will recover automatically.

■The system operation is suspended if
you:
• Set the wipers to HI.
u Turning the wipers o ff or setting it to LO
resumes the LKAS.
• Set the wiper switch to AUTO and the
wipers operate at high speed.
u The LKAS resumes when the wipers stop
or operate at low speed.
• Decrease the vehicle speed to about 40 mph
(64 km/h) or less.
u Increasing the vehicle speed to about
45 mph (72 km/h) or more resumes the
LKAS.
• Depress the brake pedal.
u The LKAS resumes and starts detecting
the lane lines again once you release the
brake pedal.
■The LKAS may automatica lly be suspended when:
• The system fails to detect lane lines.
• The steering wheel is quickly turned.
• You fail to steer the vehicle.
• Driving through a sharp curve.
• Driving at a speed in excess of approximately 90 mph (145 km/h).
Once these conditions no longer exist, the LKAS automatically resumes.
When the LKAS is suspended,
the lane lines on the multi-
information display change to
contour lines, and the beeper
sounds (if activated).
