Modes can be changed by
pressing the power switch with
the brake pedal released. (The
mode changes each time the
switch is pressed.)
WARNING
■Stopping the hybrid system
in an emergency
●If you want to stop the hybrid
system in an emergency while
driving the vehicle, press and
hold the power switch for more
than 2 seconds, or press it
briefly 3 times or more in suc-
cession. (P.457)
However, do not touch the
power switch while driving
except in an emergency. Turn-
ing the hybrid system off while
driving will not cause loss of
steering or braking control.
However, power assist for the
steering wheel may be lost mak-
ing it difficult to steer smoothly
before stopping the vehicle
depending on the remaining
charge in the 12-volt battery or
usage conditions. In this situa-
tion, you should pull over and
stop the vehicle as soon as it is
safe to do so.
●If the power switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-info rmation display
and a buzzer sounds.
●When restarting the hybrid sys-
tem after an emergency shut-
down, shift the shift lever to N
and press the power switch
shortly and firmly.
■When parking
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time. If such a situation
cannot be avoided, park the
vehicle in an open space and
ensure that exhaust fumes do
not enter the ve hicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem is operating, exhaust gases
may collect and enter the vehi-
cle.

ON, the brake pedal is depressed
and the shift release button is
pushed.
■If the shift lever cannot be
shifted from P
First, check whether the brake pedal
is being depressed.
If the shift lever cannot be shifted
even though the brake pedal is
depressed and the shift release but-
ton is pushed, there may be a prob-

A rear camera lens may be dirty or
covered with snow or ice. In such
cases, if it is removed from the rear
camera lens, the system should
return to normal. ( It may be neces-
sary to drive the vehicle for some
time before the system returns to
normal. Even afte r the camera

Clean the rear camera lens.
■Situations in which the system
may not operate properly
●Some pedestrians, such as the following, may no
t be detected by
the rear camera detection func-
tion, preventing the function from
operating properly:
• Pedestrians who are bending for- ward or squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• People riding a bicycle, skate- board, or other light vehicle
• Pedestrians wearing oversized clothing such as a rain coat, long
skirt, etc., making their silhouette
obscure
• Pedestrians whose body is par- tially hidden by an object, such as
a cart or umbrella
• Pedestrians which are obscured by darkness, such as at night
●In some situations, such as the
following, pedestrians may not be
detected by the rear camera
detection function, preventing the
function from operating properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is
obscured (dirt, snow, ice, etc. are
attached) or scratched
• When a very bright light, such as
the sun, or the headlights of
another vehicle, shines directly
into the rear camera
• When backing up in a place where the surrounding brightness
changes suddenly, such as at the
entrance or exi t of a garage or
underground parking lot
• When backing up in a dim envi-
ronment such as during dusk or in
an underground parking lot
• When the dedicated camera
cleaning washer is operating
• When the camera position and direction are deviated
• When a towing hook is attached
• When water droplets are flowing
on the camera lens
• When the vehicle height is
extremely changed (nose up,
nose down)
• When tire chains or an emergency

mately 9 mph (15 km/h) or less.
• Vehicles are approaching from the right or left at the 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.308). 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.
