2404-5. Using the driving support systems
■Vehicles that can be detected by the Blind Spot Monitor
The Blind Spot Monitor uses rear side radar sensors to detect the following vehi-
cles traveling in adjacent lanes and advises the driver of the presence of such vehi-
cles via the indicators on th e outside rear view mirrors.
Vehicles that are traveling in areas that are not visible using the outside rear
view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that are not visible
using the outside rear view mirrors (the blind spots)
■The Blind Spot Monitor detection areas
The areas that vehicles can be detected in are outlined below.
The range of each detection area is:
Approximately 1.6 ft. (0.5 m) to 11.5 ft. (3.5 m) from either side of the vehicle*1
Approximately 3.3 ft. (1 m) forward of the rear bumper
Approximately 9.8 ft. (3 m) from the rear bumper
Approximately 9.8 ft. (3 m) to 19 7 ft. (60 m) from the rear bumper
*2
*1: The area between the side of the vehicle and 1.6 ft. (0.5 m) from the side of the vehicle
cannot be detected.
*2: The greater the difference in speed between your vehicle and the detected vehicle is,

●The Blind Spot Monitor is on.
●The shift lever is in a position other than R.
●The vehicle speed is greater than approx-
imately 10 mph (16 km/h).
■The Blind Spot Monitor will detect a
vehicle when
The Blind Spot Monitor will detect a vehicle
present in the detection area in the follow-
ing situations:
●A vehicle in an adj acent lane overtakes
your vehicle.
●You overtake a vehicle in an adjacent lane
slowly.
●Another vehicle enters the detection
area when it changes lanes.
■Conditions under wh ich the Blind Spot
Monitor will not detect a vehicle
The Blind Spot Monitor is not designed to

: Depending on the conditions, detection of a vehicle and/or object may occur.
■Conditions under which the Blind Spot
Monitor may not function correctly
●The Blind Spot Monitor may not detect
vehicles correctly in the following situa-
tions:
• When the sensor is misaligned due to a
strong impact to the sensor or its sur-
rounding area
• When mud, snow, ice, a sticker, etc. is
covering the sensor or surrounding area
on the rear bumper
• When driving on a road surface that is
wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching
with only a small gap between each vehi-
cle
• When the distance between your vehicle
and a following vehicle is short
• When there is a significant difference in speed between your vehicle and the vehi-
cle that enters the detection area
• When the difference in speed between your vehicle and another vehicle is
changing
• When a vehicle enters a detection area traveling at about the same speed as your
vehicle
• As your vehicle starts from a stop, a vehi- cle remains in the detection area
• When driving up and down consecutive steep inclines, such as hills, dips in the
road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When vehicle lanes are wide, or when
driving on the edge of a lane, and the
vehicle in an adjacent lane is far away
from your vehicle
• When an accessory (such as a bicycle carrier) is installed to the rear of the vehi-
cle
• When there is a significant difference in height between your vehicle and the
vehicle that enters the detection area

■Cautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always drive safely, taking care
to observe your surroundings.
The RCTA function is only a supplemen-
tary function which alerts the driver that a
vehicle is approaching from the right or
left at the rear of the vehicle. As the
RCTA function may not function cor-
rectly under certai n conditions, the
driver’s own visual confirmation of safety
is necessary. Over re liance on this func-
tion may lead to an accident resulting
death or serious injury.
NOTICE
■Before using the RCTA function
Do not place objects near the sensors.

■Operation of the RCTA function
The RCTA function uses rear side radar sensors to detect vehicles approaching
from the right or left at the rear of the vehicle and alerts the driver of the presence
of such vehicles by flashing the outside rear view mirror indi cators and sounding a
buzzer.

■Defogging the windshield
Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch.
Set the outside/recirc ulated air mode but-
ton to outside air mode if the recirculated
air mode is used. (It may switch automati-
cally.)

dows early, turn the air flow and tempera-
ture up.
To return to the previous mode, press the
windshield defogger switch again when the
windshield is defogged.
■Defogging the rear window and

window, and to remove raindrops, dew
and frost from the outside rear view
mirrors.
Press the rear window and outside rear
view mirror defoggers switch.

■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
●Recirculated air mode is selected as a
default mode when the engine switch is
turned to IGNITION ON mode.
●It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■Fogging up of the windows
The windows will easily fog up when the
humidity in the vehicle is high. Selecting
“A/C” on will dehumidify the air from the
outlets and defog the windshield effectively.
●If you turn “A/C” off, the windows may fog
up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode tem-
porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
●Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.
■Registering air conditioning settings to
electronic keys (vehicles with driving
position memory)
●Unlocking the vehicle using an electronic
key and turning the engine switch to
IGNITION ON mode will recall that
key’s registered air conditioning settings.
●When the engine switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
●The system may not operate correctly if
more than one electr onic key is in the
vicinity or if the smart access system with
