If the Some Driver Assist Systems Cannot
Operate: message appears:
•Use the heating and cooling system*/climate
control system* to cool down the interior and, if
necessary, also use defr oster mode with the air
flow directed towards the camera.
•Start driving the vehicle to lower the windshield
temperature, which cool s down the area around
the camera.
If the Some Driver Assist Systems Cannot
Operate: message appears:
•Park your vehicle in a sa fe place, and clean the
windshield. If the message does not disappear after
you have cleaned the winds hield and driven for a
while, have your vehicle checked by a dealer.

uuWhen Driving uRoad Departure Mitigation (RDM) System*
Driving
Road Departure Mitigation (RDM) System*
Alerts and helps to assist you when the system detects a possibility of your vehicle
unintentionally crossing over detected la ne markings and/or leaving the roadway
altogether.
The front camera behind the rearview mirror
monitors left and right lane markings (in white
or yellow). If your vehicle is getting too close to
detected lane markings without a turn signal
activated, the system, in addition to a visual
alert, applies steering torque and alerts you
with rapid vibrations on the steering wheel, to
help you remain within the detected lane.
As a visual alert, the Lane Departure
message appears on the multi-information
display.
If the system determines that its steering input
is insufficient to keep your vehicle on the
roadway, it may apply braking. u Braking is applied only when the lane
markings are solid continuous lines.
The system cancels assisting operations when you turn th e steering wheel to avoid
crossing over detected lane markings.
If the system operates several times without detecting driver response, the system
beeps to alert you.
■How the System Works
1 Road Departure Mitigation (RDM) System*
Important Safety Reminder
Like all assistance systems, the RDM system has
limitations.
Over-reliance on the RDM system may result in a
collision. It is always your responsibility to keep the
vehicle within your driving lane.
The RDM system only alerts you when lane drift is
detected without a turn signal in use. The RDM
system may not detect all la ne markings or lane or
roadway departures; accu racy will vary based on
weather, speed and lane marker condition. It is
always your responsibilit y to safely operate the
vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.

improperly under the certain conditions: 2 RDM Conditions and Limitations P. 455

functions due to your opera tion of the vehicle, or

Continued
Driving
Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed and a set following interval behind a vehicle
detected ahead of yours, without you having to keep your foot on the brake or the
accelerator.1Adaptive Cruise Control (ACC)*
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe interval betw een your vehicle and other vehicles.
Be careful not to have the radar sensor cover strongly
impacted.
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below 22
mph, ACC will automatically cancel and no
longer will apply your vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.
When to use
■Vehicle speed for adaptive crui se control: Desired speed in a
range above roughly 25 mph (40 km/h) ~
■Shift positions for adaptive cruise control: In ( D
The radar sensor is in the
front grille.
The camera is located
behind the rearview
mirror.

The system may automatically shut off and the ACC indicator will come on under
certain conditions. Some examples of th ese conditions are listed below. Other
conditions may reduce some of the ACC functions.
2 Front Sensor Camera* P. 450
■Environmental conditions
Driving in bad weather (r ain, fog, snow, etc.).
■Roadway conditions
Driving on a snowy or wet roadway (obscure d lane marking, vehicle tracks, reflected
lights, road spray, high contrast).
■Vehicle conditions
• The outside of the windshie ld is blocked by dirt, mud, leaves, wet snow, etc.
• An abnormal tire or wheel condition (wrong sized, varied size or construction,
improperly inflated, comp act spare tire, etc.).
• The camera temperature gets too high.
• The parking brake is applied.
• When the radar sensor cover is dirty.
• The vehicle is tilted due to a heav y load or suspension modifications.
• When tire chains are installed.
■ACC Conditions and Limitations1ACC Conditions and Limitations
The radar sensor for ACC is shared with the collision
mitigation braking system
TM (CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM)* P. 494
Do not put a sticker on the radar sensor cover or
replace the radar sensor cover.
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehi cle checked by a dealer:
•The vehicle mounted onto a bump, curb, chock,
embankment, etc.
•You drive the vehicle where the water is deep.
•Your vehicle has a frontal collision.

■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The interval between your vehicle and the vehicle or pedestrian ahead of you is
too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• When you accelerate rapidly and approach the vehicle or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter, or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved or winding or undulating road that makes it difficult
for the sensor to properly detect a vehicle or a pedestrian in front of you.
• The speed difference between your vehicle an d a vehicle or pedestrian in front of
you is significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.
• When driving through a narrow iron bridge.
• When the vehicle ahead of you brakes suddenly.
• When the vehicle ahead of you has a unique shape.
• When your vehicle or the vehicle ahead of you is driving on one edge of the lane.

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 alerts if the ve hicle 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. 101
Do not place objects on the instrument panel.
Objects may reflect on th e front windshield and
prevent correct detectio n of the traffic lanes.
LKAS only alerts you when lane drift is detected
without a turn signal in use. LKAS may not detect all
lane markings or lane departures; a ccuracy will vary
based on weather, speed, an d 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
LKAS may not function as designed on while driving
in frequent stop and go traf fic, or on roads with
sharp curves.

* P. 450
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 operat ing the turn signals, the LKAS alerts
activate, and torque is applied to the steering.
■LKAS camera

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 beco mes stronger as the vehicle gets closer to
either of the lane lines.
