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. 411)
If the replaced fuse blows again, have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
When replacing light bulbs
Toyota recommends that you use genuine Toyota products.
Because certain bulbs are connected to circuits designed to prevent over-
load, non-genuine parts may be unusable.
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 a fire.
Do not modify the fuse or the fuse box.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional, as soon as possible.

If the hybrid system will not start
If the hybrid system still does not start after following the correct
starting procedure (P. 175), confirm the following points.
The hybrid system will not start even if you are carrying the
correct key.
One of the following may be the cause of the problem.
The electronic key may not be functioning properly.*
(P. 474)
There may not be sufficient fuel in the vehicle’s tank. Refuel
the vehicle.
The electronic key battery may be discharged. (P. 474)
There may be a malfunction in the P position control 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. 472)
There may be a malfunction in the immobilizer system.*
(P. 107)
*: It may not be possible to shift out of P.
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. 476)
The 12-volt battery terminal connections may be loose or cor-
roded.

If the 12-volt batter y 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 any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
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 and fuse block
cover.
Open the exclusive jump start-
ing terminal cover.

UK_AURIS_HV_EE
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
Avoiding a discharged 12-volt battery
Turn off the headlights and the audio system while the hybrid system is
turned off.
Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
When the 12-volt battery is removed or discharged
If the 12-volt battery is depleted with the shift position in P, it will not be
possible to shift out of P. In this case, the vehicle cannot be towed without
lifting both front wheels because the front wheels are locked by the park-
ing lock. (P. 423)
The hybrid system may not start. (P. 384)
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 oper-
ating.)
Once the hybrid system has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Close the exclusive jump starting terminal cover and rein-
stall the fuse box cover.
Once the hybrid system starts, have the vehicle checked at any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional, as soon as possible.STEP7
