■Conditions under which the
system may not function cor-
rectly
●The BSM function may not detect
vehicles correctly in the following
situations:
• When the sensor is misaligned
due to a strong impact to the sen-
sor or its surrounding area
• When mud, snow, ice, a sticker, etc., is covering the sensor or sur-
rounding 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 vehicle
• When the distanc e between your
vehicle and a following vehicle is
short
• When there is a significant differ-
ence in speed between your vehi-
cle 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 con- secutive 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 adja-
cent 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 differ- ence in height between your vehi-
cle 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
unnecessarily detecting a vehicle
and/or object may increase in the
following situations:
• When the sensor is misaligned due to a strong impact to the sen-
sor or its surrounding area
• When the distance between your vehicle and a guardrail, wall, etc.
that enters the detection area is
short
• When driving up and down con-
secutive 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 r oads with sharp
bends, consecutive curves, or
uneven surfaces
• When the tires are slipping or spinning
• When the distance between your vehicle 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
function
The RCTA function uses 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 indica-
tors and sounding a buzzer.

■The Parking Support Brake
function (rear-crossing vehi-
cles) will operate when
The function will operate when the
PKSB OFF indicator is not illumi-
nated ( P.168, 170) and all of the
following condit ions are met:
●Hybrid system output restriction
control
• The Parking Support Brake is enabled.
• The vehicle speed is approxi-
mately 9 mph (15 km/h) or less.
• Vehicles are approaching from the right or left at th e rear of the vehi-
cle at a traveling speed of approx-
imately 5 mph (8 km/h) or more.
• The shift lever is in R.
• The Parking Support Brake deter-
mines that a stronger than normal
brake operation is necessary to
avoid a collision with an approach-
ing vehicle.
●Brake control
• Hybrid system output restriction control is operating
• The Parking Support Brake deter- mines that an emergency brake
operation is necessary to avoid a
collision with an approaching vehi-
cle.
■The Parking Support Brake
function (rear-crossing vehi-
cles) will stop operating when
The function will st op operating if
any of the following conditions are
met:
●Hybrid system output restriction
control • The Parking Support Brake is dis-
abled.
• The collision becomes avoidable
with normal brake operation.
• A vehicle is no longer approaching from the right or left at the rear of
the vehicle.
●Brake control
• The Parking Support Brake is dis- abled.
• Approximately 2 seconds have
elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed
after the vehicle is stopped by
brake control.
• A vehicle is no longer approaching
from the right or left at the rear of
the vehicle.
■Detection area of the Parking
Support Brake function (rear-
crossing vehicles)
The detection area of the Parking
Support Brake function (rear-cross-
ing vehicles) differs from the detec-
tion area of the RCTA function
( P.384). Therefore, even if the
RCTA function detects a vehicle
and provides an alert, the Parking
Support Brake function (rear-cross-
ing vehicles) may not start operat-
ing.

driving at high speed on wet or
slick roads.
■Stopping distance when the
ABS is operating may exceed
that of normal conditions
The ABS is not designed to
shorten the vehicle’s stopping dis-
tance. Always maintain a safe dis-
tance from the vehicle in front of
you, especially in the following sit-
uations:
●When driving on d irt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with
potholes or uneven surfaces
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Active Cornering Assist does
not operate effectively when
●Do not overly rely on Active
Cornering Assist. Active Corner-

●Unlike the parking brake, hill-
start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.
■When the
TRAC/ABS/VSC/Trailer Sway
Control is activated
The slip indicator light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particula r care when the
