■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. 486)
● If the replaced fuse blows again, have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ 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.
■ 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 any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.

One of the following may be the cause of the problem:
● Vehicles with a smart entry & start system: The electronic key may
not be functioning properly. ( P. 573)
● There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle. ( P. 252)
● There may be a malfunction in the immobilizer system. (P. 9 6 )
● There may be a malfunction in the steering lock system.

lem such as electronic key battery depletion or a blown fuse. How-
ever, depending on the type of malfunction, an interim measure is
available to start the hybrid system. ( P. 572)
One of the following may be the cause of the problem:
● The 12-volt battery may be discharged. (P. 576)
● The 12-volt battery terminal connections may be loose or corroded.
( P. 445)
Reasons for the hybrid system not starting vary depending on

5788-2. Steps to take in an emergency
YARIS_HV_OM_Europe_OM52J66E
Maintain the engine speed of the second vehicle and start the
hybrid system of your vehicle by turning the power switch to “ON”
position (vehicles without a smart entry & start system) or ON mode
(vehicles with a smart entry & start system).
Make sure the “READY” indicator comes on. If the indicator does
not come on, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
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 any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer 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.
■ 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.)
