■After a fuse is replaced
●If the lights do not turn on even after the fuse has been repla ced, a bulb may
need replacement. ( P. 563)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.

unusable.

Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
