Precautions on BSW/Blind Spot
InterventionTMsystem
WARNING
.Do not use the Blind Spot InterventionTM
system under the following conditions
because the system may not function
properly.
—During bad weather (for example,
rain, fog, snow, wind, etc.)
—When driving on slippery roads,such as on ice or snow, etc.
—When driving on winding or uneven
roads.
—When there is a lane closure due toroad repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane width is too narrow.
—When driving with a tire that is notwithin normal tire conditions (for
example, tire wear, low tire pressure,
installation of spare tire, tire chains,
non-standard wheels).
—When the vehicle is equipped withnon-original brake parts or suspen-
sion parts.
. Do not use the BSW or Blind Spot
Intervention
TMsystems when towing a
trailer.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound, and
it may not be heard.
. The radar sensors may not be able to
detect and activate Blind Spot Interven-
tion
TM/BSW when certain objects are
present such as:
—Pedestrians, bicycles, animals
—Several types of vehicles such as motorcycles
—Oncoming vehicles
—Vehicles remaining in the detectionzone when you accelerate from a
stop
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle merging into an adjacent lane at a speed approximately the same as your vehicle
(See
“BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle approaching rapidly from behind.
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle which your vehicle over-
takes rapidly.
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
. Severe weather or road spray conditions
may reduce the ability of the radar to
detect other vehicles.
. The radar sensors detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect vehi-
cles in an adjacent lane. When driving in
a narrow lane, the radar sensors may
detect vehicles driving two lanes away.
. The radar sensors are designed to ignore
most stationary objects, however ob-
jects such as guardrails, walls, foliage

NOTE:
If you accelerate from a stop with a vehicle
in the detection zone, the other vehicle
may not be detected.
SSD1033
Overtaking other vehicles
The Blind spot warning indicator light
illuminates if you overtake a vehicle and
that vehicle stays in the detection zone for
approximately 3 seconds.
The radar sensors may not detect slower
moving vehicles if they are passed quickly.

PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the distance sensor
*Adetects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance.
The system automatically controls the
throttle and applies the brakes (up to
25% of vehicle braking power) if neces- sary.
The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING
.
This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the
system in city traffic or congested areas.
. This system will not adapt automatically
to road conditions. This system should
be used in evenly flowing traffic. Do not
use the system on roads with sharp
curves, or on icy roads, in heavy rain or
in fog.
The distance sensor will not detect the
following objects:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway .
Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
(ICC) system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Decelerate the vehicle speed by depres-
sing the brake pedal, depending on the
distance to the vehicle ahead and the
surrounding circumstances in order to
maintain a safe distance between vehi-
cles.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not function properly

5-60Starting and driving
traveling ahead. The sensor generally
detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if
the sensor cannot detect the reflector on
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:
.When the reflector of the vehicle ahead
is positioned high on the vehicle
(trailer, etc.)
. When the reflector on the vehicle ahead
is missing, damaged or covered
. When the reflector of the vehicle ahead
is covered with dirt, snow and road
spray
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When dense exhaust or other smoke
(black smoke) from vehicles reduces
the sensor’s visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
area of your vehicle
. When your vehicle is towing a trailer,
etc.
The ICC system is designed to automati- cally check the sensor’s operation within
the limitation of the system. When the
sensor is covered with dirt or obstructs, the
system will automatically be canceled. If
the sensor is covered with ice, a transpar-
ent or translucent vinyl bag, etc., the ICC
system may not detect them. In these
instances, the vehicle-to-vehicle distance
control mode may not cancel and may not
be able to maintain the selected following
distance from the vehicle ahead. Be sure to
check and clean the sensor regularly.
The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match
the slower vehicle ahead; the system will
decelerate the vehicle as necessary, and if
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill. How-
ever, the ICC system can only apply up to
25% of the vehicles total braking power.
This system should only be used when
traffic conditions allow vehicle speeds to
remain fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decele-
rates, the distance between vehicles may
become closer because the ICC system
cannot decelerate the vehicle quickly en-
ough. If this occurs, the ICC system will
sound a warning chime and blink the
system display to notify the driver to take
necessary action.
The system will cancel and a warning
chime will sound if the speed falls below
approximately 15 MPH (24 km/h) and a
vehicle is not detected ahead. The system
will also disengage when the vehicle goes
above the maximum set speed.
See
“Approach warning” later in this
section.
The following items are controlled in the
vehicle-to-vehicle distance control mode:
. When there are no vehicles traveling
ahead, the vehicle-to-vehicle distance
control mode maintains the speed set
by the driver. The set speed range is
between approximately 20 and 90 MPH
(32 and 144 km/h).
. When there is a vehicle traveling ahead,
the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by driver, from the
vehicle ahead. The adjusting speed
range is up to the set speed. If the
vehicle ahead comes to a stop, the
vehicle decelerates to a standstill with-

System operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the brake pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when
using the Intelligent Cruise Control (ICC)
system.The driver sets the desired vehicle speed
based on the road conditions. The ICC
system maintains the set vehicle speed,
similar to standard cruise control, as long
as no vehicle is detected in the lane ahead.
The ICC system displays the set speed.Vehicle detected ahead:
When a vehicle is detected in the lane
ahead, the ICC system decelerates the
vehicle by controlling the throttle and
applying the brakes to match the speed
of a slower vehicle ahead. The system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
The stoplights of the vehicle come on
when braking is performed by the ICC
system.
When the brake operates, a noise may be
heard and/or vibration may be felt. This is
not a malfunction.
When a vehicle ahead is detected, the
vehicle ahead detection indicator comes
on. The ICC system will also display the set
speed and selected distance.
Vehicle ahead not detected:
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.
When a vehicle is no longer detected the
vehicle ahead detection indicator turns off.

.The distance to the vehicle ahead will
change according to the vehicle speed.
The higher the vehicle speed, the
longer the distance.
. If the engine is stopped, the set
distance becomes “long”. (Each time
the engine is started, the initial setting becomes
“long”.)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle or if another vehicle cuts in, the
system warns the driver with the chime
and Intelligent Cruise Control (ICC) system
display. Decelerate by depressing the
brake pedal to maintain a safe vehicle
distance if:
.The chime sounds.
. The vehicle ahead detection and set
distance indicator blink.
The warning chime may not sound in some
cases when there is a short distance
between vehicles. Some examples are:
. When the vehicles are traveling at the
same speed and the distance between
vehicles is not changing
. When the vehicle ahead is traveling
faster and the distance between vehi-
cles is increasing
. When a vehicle cuts in near your vehicle
The warning chime will not sound in the
following cases:
. When your vehicle approaches vehicles
that are parked or moving slowly
. When the accelerator pedal is de-
pressed, overriding the system

5-78Starting and driving
The Distance Control Assist (DCA) system
brakes and moves the accelerator pedal
upward according to the distance from and
the relative speed of the vehicle ahead to
help assist the driver to maintain a
following distance.
WARNING
.Always drive carefully and attentively
when using the Distance Control Assist
system. Read and understand the Own-
er’s Manual thoroughly before using the
DCA system. To avoid serious injury or
death, do not rely on the system to
prevent accidents or to control the
vehicle’s speed in emergency situations.
Do not use the Distance Control Assist
system except in appropriate road and
traffic conditions.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill with
a warning chime. To prevent the vehicle
from moving, the driver must depress
the brake pedal. .
The DCA system will not apply brake
control while the driver’s foot is on the
accelerator pedal.
