4006-1. Maintenance and care
WARNING
■Water in the vehicle
●Do not splash or spill liquid in
the vehicle, such as on the floor,
on the front seats, in the hybrid
battery (traction battery) air
intake vent or in the luggage
compartment. ( P.85)
Doing so may cause the hybrid
battery, electrical components,
etc. to malfunction or catch fire.
●Do not get any of the SRS com-
ponents or wiring in the vehicle
interior wet.
(  P.42)
An electrical malfunction may
cause the airbags to deploy or
not function properly, resulting
in death or serious injury.
●Vehicles with wireless charger:
Do not let the wireless charger
(  P.381) get wet. Failure to do
so may cause the charger to
become hot and cause burns or
could cause electric shock
resulting in death or serious
injury.
■Cleaning the interior (espe-
cially instrument panel)
Do not use a polis h wax or polish
cleaner. The instrument panel
may reflect off the windshield,
obstructing the dr iver’s view and
leading to an accident, resulting in
death or serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types
of detergent, as they may dis-
color the vehicle interior or
cause streaks or damage to
painted surfaces:
• Non-seat portions: Organic sub- stances such as benzene or
gasoline, alkaline or acidic solu-
tions, dye, and bleach
• Seats: Alkaline or acidic solu- tions, such as thinner, benzene,
and alcohol
●Do not use a polish wax or pol-
ish cleaner. The instrument
panel’s or other interior part’s
painted surface may be dam-
aged.
■Water on the floor
Do not wash the v ehicle floor with
water.
Vehicle systems such as the
audio system may be damaged if
water comes into contact with
electrical components such as the
audio system above or under the
floor of the vehicle. Water may
also cause the body to rust.
■When cleaning the inside of
the windshield
Do not allow glass cleaner to con-
tact the lens. Also, do not touch
the lens. ( P.264)
■Cleaning the inside of the rear
window

5067-2. Steps to take in an emergency
recharge the 12-volt battery
of your vehicle.
6 Open and close any of the
doors of your vehicle with the
power switch OFF.
7 Maintain the engine speed of
the second vehicle and start
the hybrid system of your
vehicle by turning the power
switch to ON.
8 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
9 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
10 Close the exclusive jump
starting terminal cover, and
reinstall the fuse box cover to
its original position.
Once the hybrid system starts,
have the vehicle inspected at
your Toyota dealer as soon as
possible.
■Starting the hybrid system
when the 12-volt battery is dis-
charged
The hybrid system cannot be
started by push-starting.
■To prevent 12-vol t battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnec essary 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 stored 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.551)
■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 12-volt battery
The electricity stored in the 12-volt
battery will discha rge gradually even
when the vehicle i s not in use, due
to natural dischar ge 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 hybrid system may
be unable to start. (The 12-volt bat-
tery recharges automatically while
the hybrid system is operating.)
■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 hybrid syste m may not start
on the first attemp t after reinstall-
ing the 12-volt battery. In that
case, start the hybrid system in
the same manner as when the
electronic key does not operate
properly ( P.503). This is not a
malfunction, as the hybrid system
will start normally on the second
attempt.

tion. In a closed area such as a
garage, exhaust gases including
harmful carbon monoxide (CO)
may collect and enter the vehicle.
This may lead to death or a seri-
ous health hazard.
