Lane Keeping Assist System (LKAS)
*
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides audible and visual alerts 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 vehicle control. The system does
not work if you take your hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 113
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; 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. 384

Driving
The system may not detect lane markings and therefore may not keep the vehicle in
the middle of a lane under certain conditions, including the following:■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interior of the front windshield.■Roadway conditions
• Driving on a snowy or wet roadway (obscured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on a road with temporary lane markings.
• Faint, multiple, or varied lane markings are visible on the roadway due to road
repairs or old lane markings.
• The roadway has merging, split, or crossing lines (e.g., such as at an intersection
or crosswalk).
• The lane markings are extremely narrow, wide, or changing.
• The vehicle in front of you is driving near the lane lines.
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving over bumps.■

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.

This button is on the driver side control panel.
To partially turn the VSA features on and off,
press and hold it until you hear a beep.
The traction control stops fully functioning,
allowing the wheels to spin more freely at low
speed. The VSA ® OFF indicator will also come
on.
To turn it on again, press the (VSA ® OFF)
button until you hear a beep.
VSA ® is turned on every time you start the
engine, even if you turned it off the last time
you drove the vehicle.
■
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.

Agile Handling Assist SystemLightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehicle’s stability and performance during
cornering.Precision All Wheel Steer System
*
Monitors road conditions while you are driving. In response to current driving
conditions, the system automatically makes slight adjustment to the relative rear
wheel toe settings to help enhance vehicle control and stability.
1Agile Handling Assist System
The agile handling assist system cannot enhance
stability in all driving situations. You still need to drive
and corner at speeds appropriate for the conditions
and always leave a suffi cient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agile handling assist system
does not activate.
You may hear a sound coming from the engine
compartment while the system is activated. This is
normal.1 Precision All Wheel Steer System
*
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.

Driving
Blind Spot Information (BSI) System
*
Is designed to detect vehicles in specified alert zones adjacent to your vehicle,
particularly in harder to see areas common ly known as “blind spots.”
When the system detects vehicles approaching from behind in adjacent lanes, the
appropriate indicator comes on for a few seconds, providing assistance when you
change lanes.■How the system works
1 Blind Spot Information (BSI) System
*
Important Safety Reminder
Like all assistance systems, BSI has limitations. Over
reliance on BSI may result in a collision.
The system is for your convenience only. Even if an
object is within the alert zone, the following
situations may occur.•The BSI alert indi cator may not come on due to
obstruction (splashes, etc.) even without the Blind
Spot Not Available multi-information display
appearing.•The BSI alert indicator may come on even with the
message appearing.
The BSI alert indicator may not come on under the
following conditions:•A vehicle does not stay in the alert zone for more
than two seconds.•A vehicle is parked in a side lane.•The speed difference between your vehicle and the
vehicle you are passing is greater than 6 mph (10
km/h).•An object not detected by the radar sensors
approaches or passes your vehicle.

WARNING
Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on the blind spot
information system when changing lanes.
Always look in your mirrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.
