■The system operation is suspended if
you:
• Set the wipers to continuous operation.
u Turning the wipers off resumes the
LKAS.
• 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.
• Set the wiper switch to AUTO and the
wipers operate continuously.
u The LKAS resumes when the wipers stop
or operate intermittently.
■The LKAS may automatically be suspended when:
• The system fails to detect lane lines.
• The steering wheel is quickly turned.
• You fail to steer the vehicle.
• The vehicle runs on a curved road over the speed limit.
Once these conditions no longer exist, the LKAS automatically resumes.
When the LKAS is suspended,
the lane lines on the multi-
information disp lay change to
contour lines, and the beeper
sounds.

• The camera temperature gets too high.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• When driving through a sharp curve.
• When driving at a speed in excess of approximately 90 mph (145 km/h).

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 reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects ar e 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 extremel y 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
Vehicle Stability Assist (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering 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 ou tput and selectively applying the brakes.
When VSA ® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® 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 vehi cle 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 corner at speeds appropriate
for the conditions and alwa ys 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.

Driving
This button is on the driver side control panel.
To turn the VSA® system on and off, press and
hold it until you hear a beep.
VSA® will stop and the indicator will 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 ® On and Off1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control
(ESC), System
Without VSA ®, your vehicle will have normal braking
and cornering ability, bu t it will not have VSA®
traction and stability enhancement.
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the VSA ® system is off, the traction control
system is also off. You should only atte mpt to free
your vehicle with the VSA ® off if you ar e not able to
free it when the VSA ® is on.
Immediately after freeing your vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® and traction control
systems switched off.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.

uuWhen Driving uBlind spot information (BSI) System*
Continued
Driving
Blind spot informa tion (BSI) System*
Is designed to detect vehicles in specified alert zones adjacent to your vehicle,
particularly in harder to see areas commonly known as “blind spots.”
When the system detects vehicles approach ing from behind in adjacent lanes, the
appropriate indicator comes on for a few se conds, providing assistance when you
change lanes.
■How the system works
1 Blind spot inform ation (BSI) System*
Important Safety Reminder
Like all assistance systems, BSI has limitations. Over
reliance on BSI may re sult 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 indicator may not come on due to
obstruction (splashes, et c.) even without the BLIND
SPOT NOT AVAILABLE/Blind Spot Info Not
Available multi-information display appearing.
•The BSI alert indicator may come on even with the
message appearing.
3WARNING
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 wh en changing lanes.
Always look in your mirrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.
Radar sensors detect a
vehicle in the alert zone
when your vehicle is
moving forward at
between 20 mph (32 km/h)
and 100 mph (160 km/h). Alert zone range
A: Approx. 1.6 ft. (0.5 m)
B: Approx. 10 ft. (3 m)
C: Approx. 10 ft. (3 m) Radar Sensors:
