■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. 355)
● If the replaced fuse blows again, have the vehicle inspected by your Toy-
ota dealer.
■ If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.
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 fire.
● Do not modify fuses or the fuse box.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your Toy-
ota dealer.

AVALON_U_(L/O_0802)
Emergency start function (vehicles with smart key system)When the engine does not start, th e following steps can be used as
an interim measure to start the engine if the “ENGINE START STOP”
switch is functioning normally.
Set the parking brake.
Shift the shift lever to “P”.
Set the “ENGINE START STOP” switch to the ACC mode.
Push and hold the “ENGINE START STOP” switch about 15
seconds while depressing the brake pedal firmly.
Even if the engine can be started using the above steps, the system
may be malfunctioning. Have the vehicle checked by your Toyota
dealer.
■ The starter motor does not turn over (vehicles with smart
key system).
The engine starting system may be malfunctioning due to an
electrical problem such as an open circuit or a blown fuse. How-
ever, an interim measure is available to start the engine. 
(  P. 122)
■ The starter motor does not turn over, the interior lights and
headlights do not turn on, or the horn does not sound
One of the following may be the cause of the problem.
● One or both of the battery terminals may be disconnected.
● The battery may be discharged. ( P. 397)
● There may be a malfunction in the steering lock system (vehi-
cles with smart key system).
Contact your Toyota dealer if the problem cannot be repaired, or if
