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. 510)
If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
Never use a fuse of a higher amperage rating than 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.
This can cause extensive damage or even fire.
Do not modify fuses or the fuse box.
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.

5-2. Steps to take in an emergency
If the hybrid system will not start
Reasons for the hybrid system not starting vary depending on the
situation. Check the following and perform the appropriate proce-
dure:
The hybrid system will not start, even though the correct
starting procedure is being followed. (
P. 179, 184)
One of the following may be the cause of the problem.
The electronic key may not be functioning properly. (
P. 556)
There may be a malfunction in the immobilizer system.
(
P. 123)
There may be a malfunction in the steering lock system.
The hybrid system may be malfunctioning due to an electrical
problem such as an open circuit or a blown fuse. However,
depending on the type of malfunction, an interim measure is
available to start the hybrid system. (
P. 553)
The interior lights and headlights are dim, or the horn does
not sound or sounds at a low volume.
One of the following may be the cause of the problem.
The 12-volt battery may be discharged. (
P. 558)
The 12-volt battery terminal connections may be loose or cor-
roded.
558
5-2. Steps to take in an emergency
If the 12-volt battery is discharged
The following procedures may be used to start the hybrid system if
the vehicle's 12-volt battery is discharged.
You can call your Toyota dealer or qualified repair shop.
If you have a set of jumper (or booster) cables and a second vehi-
cle with a 12-volt battery, you can jump start your Toyota following
the steps below.
Open the hood.
Remove the fuse box cover and open the exclusive jump
starting terminal cover.
Connect the jumper cables according to the following procedure:
Connect a positive jumper cable clamp to the exclusive jump
starting terminal on your vehicle
Connect a positive jumper cable clamp to the positive (+) battery
terminal on the second vehicle
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the exclu-
sive jump starting terminal and any moving parts, as shown in
the illustration.
