Maintenance and care
After a fuse is replaced
If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (
P. 420)
If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
Do not modify the fuses or fuse boxes.
Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring
near the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer as soon as possible.

interim measure is available to start the hybrid system. (
P. 474)
One of the following may be the cause of the problem:
The 12-volt battery may be discharged. (

8-2. Steps to take in an emergency
Make sure the “READY” indicator comes on. If the indicator does
not come on, contact your Toyota dealer.
Once the hybrid system has started, remove the jumper cables in
the exact reverse order from which they were connected.
Close the exclusive jump starting terminal cover, and reinstall the
fuse box cover to its original position.
When installing, first hook the fuse box cover onto the two rear tabs.
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 discharged
The hybrid system cannot be started by push-starting.
To prevent 12-volt battery discharge
Turn off the headlights and the audio system while the hybrid system is off.
Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
Precautions when the 12-volt battery is discharged (vehicles with a
smart key system)
In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the 12-volt battery has been disconnected and
reconnected. Use the wireless remote control or the mechanical key to lock
or unlock the doors.
The hybrid 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 memorized 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 disconnecting the 12-volt battery,
turn the “POWER” switch off.
If the “POWER” switch was in ACCESSORY or ON mode before the 12-volt
battery was discharged, the audio system and/or air conditioning system
may operate when the 12-volt battery is reconnected.
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of
certain electrical appliances. If the vehicle is left for a long time, the 12-volt
battery may discharge, and the hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)
