■Front camera installation area
on the windshield
If the system determines that the
windshield may be fogged up, it
will automatically operate the
heater to defog the part of the
windshield around the front cam-
era. When cleaning, etc., be care-
ful not to touch the area around
the front camera until the wind-
shield has cooled sufficiently, as
touching it may cause burns.
■Precautions for the driver
monitor camera (if equipped)
Observe the following precau-
tions.
Failure to do so may lead to mal-
function of the driver monitor cam-
era and the systems not operating
properly, possibly leading to an

When trouble arises
depending on the type of mal-
function, an interim measure
is available to start the hybrid
system. (P.585)
 There is a possibility that the
temperature of the hybrid bat-
tery (traction battery) is
extremely low (approximately
below -22°F [-30°C]). ( P.84,
252)
*: 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.589)
 The 12-volt battery terminal
connections may be loose or
corroded. ( P.512)
One of the following may be the
cause of the problem:
 The 12-volt battery may be
discharged. ( P.589)
 One or both of the 12-volt bat-
tery terminals may be discon-
nected. ( P.512) Contact your Toyota dealer if
the problem cannot be repaired,
or if repair procedures are
unknown.
When the hybrid system does
not start, the following steps can
be used as an interim measure
to start the hybrid system if the
power switch is functioning nor-
mally.
Do not use this starting proce-
dure except in cases of emer-
gency.
1
Pull the parking brake switch
to check that the parking
brake is set. ( P.263)
