Forward Collision Warning (FCW) with Pedestrian Detection
*
Alerts you when it determines the possibility of your vehicle colliding with a vehicle
or pedestrian detected in front of you.
If the system determines a collision is possible, it gives visual and audible alerts.
u Take appropriate action to prevent a collision (apply the brakes, change lanes,
etc.).■How the system works
For a possible collision with a vehicle: Warnings may be given when your vehicle
speed is about 10 mph (15 km/h) and above.
For a possible collision with a pedestrian: Warnings may be given when your vehicle
speed is between about 10 and 62 mph (15 and 100 km/h).
1 Forward Collision Warning (FCW) with Pedestrian Detection

Important Safety Reminder
FCW with Pe destrian Detection cannot detect all
objects ahead and may not detect a given object;
accuracy of the system will vary based on weather,
speed and other factors. FCW with Pedestrian
Detection does not include a braking function. It is
always your responsibility to safely operate the
vehicle and avoid collisions.
You can change the Forward Collision Warning
Distance setting or turn the system on and off.

■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The distance 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, bic ycle, mobility scooter or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved winding or undulating road that makes it difficult for
the sensor to properly detect a vehicle in front of you.
• The speed difference between your vehicle and a vehicle in front of you is
significantly large.
• When there is a group of people in front of your vehicle walking together side by
side.
• Surrounding conditions or belongings of the pedestrian alter the pedestrian’s
shape, preventing the system from recognizing that the person is a pedestrian.
• When the pedestrian is squatting.
• When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.Limitations applicable to pedestrian detection only

Driving
Lane Departure Warning (LDW)
*
Alerts you when the system determines a possibility of your vehicle unintentionally
crossing over detected lane markings.
If your vehicle is getting too close to detected
left or right side lane markings without a turn
signal activated, LDW will give audible and
visual alerts.
The beeper sounds and the Lane Departure
message appears on the multi-information
display, letting you know that you need to
take appropriate action.
The system begins to search for lane markings when all the following conditions are
met:
• The vehicle is traveling between 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.■

Important Safety Reminder
Like all assistance systems, LDW has limitations.
Over-reliance on LDW may result in a collision. It is
always your responsibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in use. LDW 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

Driving
Road Departure Mitigation (RDM) System
*
Alerts and helps to assist you when the system determines a possibility of your
vehicle unintentionally crossing over detected lane markings.
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, steers the vehicle with rapid
vibrations on the steering wheel, to help you
remain within your driving 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 the 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.■

uuWhen Driving uVehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
Driving
Vehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), SystemVSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine output and selectively applying the brakes.
When the VSA® system indicator comes on
and stays on while driving, there may be a
problem with the system. While this may not
interfere with normal driving, have your
vehicle checked by a dealer immediately.■
VSA ® Operation
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
The VSA ® may not function properly if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the ai r pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and cor ner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.

VSA ® OFF Button
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
With the button pressed, your vehicle will have
normal braking and cornering ability, but VSA ®
traction and stability enhancement becomes less
effective.
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fresh snow, it may be easier
to free it with the button pressed.
When the button is pressed, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the button
pressed if you are not able to free it without.
Immediately after freeing your vehicle, be sure to
press the button again. We do not recommend
driving your vehicle with the button pressed
(indicator on).
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediatel y after starting the engine or
while driving. This is normal.

The Precision All Wheel Steer System cannot enhance
vehicle control and stability in all driving situations.
You still need to drive and corner at speeds
appropriate for the conditions and always leave a
sufficient margin of safety.
The toe setting of the rear wheels may get stuck in a
non-centered setting if the system malfunctions
while driving. This can cause the vehicle to pull to a
side even as you keep the steering wheel in the
center position. If this occurs, the system
automatically limits the vehicle speed to a maximum
of 50 mph (80 km/h). Reduce your speed and be
extra cautious, as handling may be difficult. Go to a
dealer immediately.
