2018 KIA OPTIMA HYBRID fuses

H35
The Hybrid battery uses high voltage
top operate the electric motor and
other components and other compo-
nents. High voltage is dangerous if
touched.
Your vehicle is equipped with orange
colored insulation and covers over
the high voltage components to pro-
tect people from electric shock. High
voltage warning labels are attached
to some system components as
additional warnings. Your vehicle is
recommended to be serviced by an
authorized Kia dealer.
WARNING - High voltage
components
Never touch orange or high volt-
age labeled components includ-
ing wires, cables, and connec-
tions. If the insulators or covers
are damaged or removed, severe
injury or death from electrocu-
tion may occur.
WARNING- Touching HPCU
When replacing the fuses in the
engine compartment, never
touch the HPCU. The HPCU car-
ries high voltage. Touching the
HPCU could result in electrocu-
tion, serious injury, or death.

FUSES
❈ Left side : Normal , Right side : Blown
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will melt.
If the electrical system does not
work, first check the driver’s side
fuse panel.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized Kia
dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.
Do not arbitrarily modify or add-on electric wiring to the vehicle.
WARNING- Fuse replace-
ment
Never replace a fuse with any- thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or alu- minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.

✽
✽NOTICE
• When replacing fuse, turn the
ignition “OFF” and turn off
switches of all electrical devices
then remove battery (-) terminal.
• The actual fuse/relay panel label may differ from equipped items.
Inner panel fuse replacement
1. Turn the engine start/stop button
to the OFF position and all other
switches off.
2. Open the fuse panel cover.
If the switch is located in the “OFF”
position, a caution indicator will be
displayed in the cluster.
OJF075022
WARNING- Electrical Fire
Always ensure replacements
fuses and relays are securely
fastened when installed. Failure
to do so can result in a vehicle
fire.
CAUTION
When replacing a blown fuse or relay, make sure the newfuse or relay fits tightly intothe clips. Failure to tightlyinstall the fuse or relay maycause damage to the wiringand electric systems.
Do not remove fuses, relays and terminals fastened withbolts or nuts. The fuses, relaysand terminals may not be fas-tened correctly which maycause vehicle damage.

3. Pull the suspected fuse straight
out. Use the removal tool provided
on the engine compartment fuse
panel cover.
4. Check the removed fuse; replace it if it is blown.
Spare fuses are provided in theengine 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 authorized
Kia dealer.
If you do not have a spare, use a fuse of the same rating from a circuityou may not need for operating thevehicle, such as the power outletfuse.
If the head lamp, turn signal lamp,
stop signal lamp, fog lamp, DRL, tail
lamp, HMSL do not work and the
fuses are OK, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced.
✽ ✽ NOTICE
If the headlamp, fog lamp, turn sig-
nal lamp, or tail lamp malfunction
even without any problem to the
lamps, have the vehicle checked by
an authorized Kia dealer for assis-
tance.
OJFH075023
CAUTION - Fuse Panel
Covers
Set all switches to ON before
driving.
If the vehicle is going to be unused for over 1 month, setall switches to OFF to preventthe batteries from draining.
The contact points of the switches may wear out withexcessive use. Please refrainfrom excessive use of theswitches (except for long-termparking for over 1 month).

Maintenance
Fuse switch
Always set the fuse switch to the ON
position before using the vehicle.
If you move the switch to the OFF
position, some items such as audio
and digital clock must be reset and
transmitter (or smart key) may not
work properly. When the switch is
Off, the caution indicator will be dis-
played on the instrument cluster.
Always place the fuse switch in the
ON position while driving the vehicle.
If the switch is located in the “OFF”
position, a caution indicator will be
displayed in the cluster.
Engine compartment fuse
replacement
1. Turn the engine start/stop buttonto the OFF position and all other
switches off.
2. Remove the fuse panel cover by pressing the tab and pulling the
cover up. When the blade type
fuse is disconnected, remove it by
using the clip designed for chang-
ing fuses located in the engine
compartment fuse box. Upon
removal, securely insert reserve
fuse of the same rating. 3. 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.
4. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized Kia dealer.

Maintenance
✽
✽NOTICE
The electronic system may not func-
tion correctly even when the engine
compartment and internal fuse
box’s individual fuses are not dis-
connected. 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, have the
vehicle checked by an authorized
Kia dealer.
✽ ✽NOTICE- Random wiring pro-
hibited when retrofitting equip-
ment
Use of random wiring in the vehicle
might cause danger due to failure
and damage of the vehicle’s per-
formance.
Using random wires especially when
retrofitting AVN or theft alarm sys-
tem, remote engine control, car
phone or radio might damage the
vehicle or cause fire.
✽ ✽ NOTICE- Remodeling
Prohibited
Do not try remodeling the vehicle in
any way. It is illegal, and may affect
the vehicle’s performance, durabili-
ty, and safety. Warranty is also not
provided for problems caused by
remodeling.
Be aware of safety problems caused
by remodeling the vehicle with
unauthorized electrical
devices(lamp, black box, electrical
equipment, diagnostic device, com-
munication device, etc.). It might
cause malfunction of the vehicle,
wiring damage, battery discharge,
connector damage, or fire. the vehi-
cle or cause fire.
CAUTION
Visually inspect the battery capto ensure it is securely closed.If the battery cap is not securelyclosed, moisture may enter thesystem and damage the electri-cal components.
