Instrument panel fuse replace-
ment
1. Turn the vehicle off.
2. Turn all other switches off.
3. Open the fuse panel cover.
4. Refer to the label on the inside of
the fuse panel cover to locate the
suspected fuse location.5. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuses
panel.
6. Check the removed fuse; replace it
if it is blown. Spare fuses are pro-
vided in the instrument panel fuse
panels (or in the engine compart-
ment fuse panel).
7. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips. If it fits loosely, we rec-
ommend that you consult an
authorised HYUNDAI dealer.In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not
need for operating the vehicle, such
as the cigarette lighter fuse.
If the headlamps or other electrical
components do not work and the
fuses are undamaged, check the
fuse panel in the engine compart-
ment. If a fuse is blown, it must be
replaced with the same rating.

4. Check the removed fuse; replace it
if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
5. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorised HYUNDAI dealer.
After checking the fuse panel in
the engine compartment, securely
install the fuse panel cover. You
may hear a clicking sound if the
cover is securely latched. If it is
not securely latched, electrical
failure may occur from water con-
tact.
Main fuse (Plug-in hybrid vehi-
cle)
The electronic system may not func-
tion correctly even when the fuses
located in the engine compartment
and instrument panel are not discon-
nected. In such case, the cause of
the problem may be disconnection of
the main fuse (BFT type), which is
located inside the positive battery
terminal (+) cap. Since the main fuse
is designed more intricately than
other parts, we recommend you visit
the nearest HYUNDAI dealer.
Information
After inspection always securely
install the battery cap. If it is not
securely latched, electrical failure may
occur from water contact.
Multi fuse
If the multi fuse is blown, we recom-
mend that you consult an authorised
HYUNDAI dealer.
