Fuses And Circuit Breakers; Underhood Compartment Fuse; Block - GMC HUMMER EV 2023 Owner's Manual

If the overload is caused by an electrical
problem and not snow or ice, be sure to get
it fixed.

Fuses and Circuit Breakers

The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit breakers.
This greatly reduces the chance of damage
caused by electrical problems.
Danger
Fuses and circuit breakers are marked
with their ampere rating. Do not exceed
the specified amperage rating when
replacing fuses and circuit breakers. Use
of an oversized fuse or circuit breaker can
result in a vehicle fire. You and others
could be seriously injured or killed.
Warning
Installation or use of fuses that do not
meet GM s original fuse specifications is
dangerous. The fuses could fail, and result
in a fire. You or others could be injured
or killed, and the vehicle could be
damaged.
