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. 467)
● 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.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.
CAUTION
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage, 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.
This can cause extensive damage or even fire.
● 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.

5-2. Steps to take in an emergency
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at
that level for approximately
5 minutes to recharge the battery of your vehicle.
Maintain the engine speed of the second vehicle and start
the hybrid system of your ve hicle by turning the “POWER”
switch to ON mode.
Make sure the “READY” indicator comes on. If the indicator
light does not come on, contact your Toyota dealer.
Once the hybrid system has started, remove the jumper
cables in the exact reverse or der from which they were con-
nected.
Close the exclusive jump starting terminal cover, and rein-
stall the fuse box cover to its original position.
When installing, first hook the fuse box cover onto the two rear

Once the hybrid system starts , have the vehicle inspected at
