Maintenance and care
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. 660)
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 before the entire wiring harness is damaged.
CAUTION
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure 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 Lexus 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 Lexus
dealer as soon as possible.

5-2. Steps to take in an emergency
If the engine will not start
If the engine will not start even though correct starting procedures are
being followed (
P. 179), consider each of the following points:
The engine will not start even when the starter motor operates
normally
One of the following may be the cause of the problem:
There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
The engine may be flooded.
Try to restart the engine once more following correct starting
procedures. (
P. 179)
There may be a malfunction in the engine immobilizer system.
(
P. 114)
The starter motor turns over slowly, 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 battery may be discharged. (
P. 741)
The battery terminal connections may be loose or corroded.
The starter motor does not turn over
The engine starting system may be malfunctioning due to an electri-
cal problem such as an open circuit or a blown fuse. However, an
interim measure is available to start the engine. (
P. 738)
