replacement. (

●

If the replaced fuse blows again, have the vehicle inspected by your Lexus dealer.

If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.

When replacing light bulbs
Lexus recommends that you use genuine Lexus products designed for this vehicle.

Because certain bulbs are connected to circuits designed to prevent overload, nongenu-

ine 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 Lexus fuse or equivalent.

Never replace a fuse with a wire, even as a temporary fix.

●

Do not modify the fuses or fuse boxes.

■
