5-5. Using the driving support systems
Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
WARNING
●When there is rain, snow, etc. on the front surface of the radar or
front camera
●In traffic conditions that require fre-
quent repeated acceleration and deceleration
●When your vehicle is towing a trailer or during emergency towing
●When an approach warning buzzer is heard often

■Conditions under which the system
may not function correctly
●The BSM function may not detect
vehicles correctly in the following situ-
ations:
• When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
• When mud, snow, ice, a sticker, etc.,
is covering the sensor or surrounding
area on the rear bumper

wet with standing water during bad
weather, such as heavy rain, snow, or
fog
• When multiple vehicles are approach-
ing with only a small gap between
each vehicle
• When the distance between your vehi-
cle and a following vehicle is short
• When there is a significant difference
in speed between your vehicle and
the vehicle 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
vehicle remains in the detection area
• When driving up and down consecu-
tive 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
vehicle
• When there is a significant difference
in height between your vehicle and
the vehicle that enters the detection
area
• Immediately after the BSM func-
tion/RCTA function are turned on
• When towing a trailer
●Instances of the BSM function unnec-
essarily detecting a vehicle and/or
object may increase in the following
situations:
• When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
• When the distance between your vehi-
cle and a guardrail, wall, etc. that
enters the detection area is short
• When driving up and down consecu-
tive steep inclines, such as hills, dips
in the road, etc.
• When vehicle lanes are narrow, or
when driving on the edge of a lane,
and a vehicle traveling in a lane other
than the adjacent lanes enters the
detection area
• When driving on roads with sharp
bends, consecutive curves, or uneven
surfaces
• When the tires are slipping or spinning
• When the distance between your vehi-
cle and a following vehicle is short
• When an accessory (such as a bicycle
carrier) is installed to the rear of the
vehicle
• When the vehicle throws up water or
snow behind.
■Operation of the RCTA func-
tion
The RCTA function uses radar sen-
sors 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
indicators and sounding a buzzer.

space next to your vehicle
●Vehicles that the sensors cannot
detect due to obstructions

not operate properly
The RCTA function may not detect vehi-
cles correctly in the following situations:

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 approach-
ing with only a small gap between
each vehicle.

tion area.
■Situations in which the system may
operate even if there is no possibil-
ity of a collision

essarily detecting a vehicle and/or
object may increase in the following situ-
ations:
●When the parking space faces a
street and vehicles are being driven
on the street.
●When the distance between your vehi-
cle and metal objects, such as a
guardrail, wall, sign, or parked vehicle,
which may reflect electrical waves
toward the rear of the vehicle, is short.

NOTICE
■If “Parking Support Brake Unavailable” is displayed on the
multi-information display and the PKSB OFF indicator illuminates
If this message is displayed immedi-
ately after the power switch is changed to ON, operate the vehicle carefully, paying attention to your sur-
roundings. It may be necessary to drive the vehicle for a certain amount of time before the system returns to
normal. (If the system does not return to normal after driving for a while, clean the sensors and their surround-
ing area on the bumpers.)
