2805-5. Using the driving support systems
Owners Manual_USA_M62064_enwhen the R shift position is
selected, the rear camera lens
may be dirty. Clean the rear cam-
era lens.
■Situations in which the system
may not operate properly
●Some pedestrians, such as the
following, may not 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 exit of a garage or
underground parking lot
• When backing up i n a dim envi-
ronment such as during dusk or in
an underground parking lot
• 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
tire puncture repair kit is used
• If the suspension has been modi- fied or tires of a size other than
specified are installed
• If an electronic component, such as a backlit license plate or rear
fog light, is insta lled near the rear
camera
• If a bumper protector, such as an
additional trim strip, is installed to
the rear bumper
■Situations in which the system
may operate unexpectedly
●Even though there are no pedes-
trians in the detection area, some
objects, such as the following,
may be detected, possibly caus-
ing the rear cam era detection
function to operate.
• Three dimensional objects, such as a pole, traffic cone, fence, or
parked vehicle
• Moving objects, such as a car or motorcycle
• Objects moving to ward your vehi-
cle when backing up, such as
flags or puddles (or airborne mat-
ter, such as smoke, steam, rain, or
snow)
• Cobblestone or gravel roads, tram
rails, road repai rs, white lines,
pedestrian crossings or fallen
leaves on the road
• Metal covers (gratings), such as those used for drainage ditches
• Objects reflected in a puddle or on
a wet road surface
• Shadows on the road
●In some situations, such as the
following, the rea r camera detec-
tion function may operate even
though there are no pedestrians in
the detection area.
• When backing up toward the road- side or a bump on the road
• When backing up toward an incline/decline

4808-2. Steps to take in an emergency
Owners Manual_USA_M62064_en
One of the following may be the
cause of the problem:
The electronic key may not be
functioning properly.
( P.482)
 There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle.
 The fuel door may be open.
( P.212)
 There may be a malfunction
in the immobilizer system.
( P. 7 0 )
 There may be a malfunction
in the shift control system.
*
( P.183, 465)
 The fuel cell system may be
malfunctioning due to an elec-
trical problem such as elec-
tronic key battery depletion or
a blown fuse. However, depending on the type of mal-
function, an interim measure
is available to start the fuel
cell system. (
P.481)
 There is a possibility that the
temperature of the traction
battery is extremely low
(approximately below -22˚F [-
30˚C]). ( P.85, 180)
 It is possible the fuel cell sys-
tem is frozen. ( P.180)
*: It may not be possible to shift the
shift position from P.
One of the following may be the
cause of the problem:
 The 12-volt battery may be
discharged. ( P.485)
 The 12-volt battery terminal
connections may be loose or
corroded. ( P.413)
One of the following may be the
cause of the problem:
 One or both of the 12-volt bat-
tery terminals may be discon-
nected. ( P.413)
If the fuel cell system
will not start
Reasons for the fuel cell
system not starting vary
depending on the situation.
Check the following and
perform the appropriate
procedure:
The fuel cell system will
not start even though the
correct starting procedure
is being followed.
( P.180)
The interior lights and
headlights are dim, or the
horn does not sound or
sounds at a low volume.
The interior lights and
headlights do not turn on,
or the horn does not
sound.

When trouble arises
■Starting the fuel cell system
when the 12-volt battery is dis-
charged
The fuel cell system cannot be
started by push-starting.
■To prevent 12-volt battery dis-
charge
●Turn off the headlights and the
audio system while the fuel cell
system is off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the 12-volt battery is
removed or discharged
●Information stor ed in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at you r Toyota dealer.
●Some systems may require initial-
ization. ( P.526)
●If the 12-volt battery discharges, it
may not be possible to shift the
shift position to other positions.
In this case, the vehicle cannot be
towed without lifting both rear
wheels because the rear wheels will
be locked.
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cleared. Before
removing the 12-volt battery termi-
nals, contact your Toyota dealer.
■Charging the 1 2-volt battery
The electricity stor ed in the 12-volt
battery will discharge gradually even
when the vehicle is not in use, due
to natural discharge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the fuel cell system
may be unable to s tart. (The 12-volt battery recharges automatically
while the fuel cell
system is operat-
ing.)
■When recharging or replacing
the 12-volt battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the 12-
volt battery is discharged. Use the
wireless remote c ontrol or the
mechanical key to lock or unlock
the doors.
●The fuel cell system may not start
on the first attempt after the 12-
volt battery has recharged but will
start normally after the second
attempt. This is not a malfunction.
●The power switch mode is memo-
rized by the vehicle. When the 12-
volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
If you are unsure what mode the
power switch was in before the
12-volt battery discharged, be
especially careful when recon-
necting the 12-volt battery.
●When the 12-volt battery is recon-
nected, start the fuel cell system,
depress the brake pedal, and con-
firm that it is possible to shift into
each shift position.
●If the battery is removed or the ter-
minals disconnected without oper-
ating the water release function
during cold weather, the vehicle
may not start due to the fuel cell
system being frozen. To prevent
this, operate th e water release
function before removing the bat-
tery or disconnecting the termi-
nals. ( P.196)
