CAUTION
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.

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 con-
nected.
Close the exclusive jump starting terminal cover, and rein-
stall the fuse box cover to its original position.
