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. 623)
If the replaced fuse blows again, have the vehicle inspected by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
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.
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.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional as soon as possible.

ever, depending on the type of malfunction, an interim measure is
available to start the hybrid system. (
P. 677)
There is a possibility that the temperature of the hybrid battery
(traction battery) is extremely low (approximately below -30
C
[-22
F]). (

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 vehicle by turning the “POWER”
switch to ON mode.

dealer or repairer, or another duly qualified and equipped
professional.
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.
When installing, first hook the fuse box cover onto the two rear
tabs.
