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 be melted or broken.
If the electrical system does not
work, first check the driver's side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-
ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer. Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.
NOTICE
NEVER replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not 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
possibly a fire.

Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
Information
After heavy driving rain or washing,
lamps could appear frosty. This condi-
tion is caused by the temperature dif-
ference between the lamp inside and
the outside temperature. This is simi-
lar to the condensation on your win-
dows inside your vehicle when raining
and doesn 't indicate a problem with
your vehicle. If the water leaks into
the lamp bulb circuitry, have your
vehicle checked by an authorized
HYUNDAI dealer.

Prior to replacing a lamp,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the Engine Start/Stop button
to the OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.

Starting the Vehicle
1. Carry the smart key or leave itinside the vehicle.
2. Make sure the parking brake is firmly applied.
3. Place the shift lever in P (Park). With the shift lever in N (Neutral),
you cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop but- ton. If the hybrid system starts, the
" " indicator will come on.
Whether the engine is cold or warm, it should be started without
depressing the accelerator.
After following the start proce-
dures, " " indicator on the
instrument cluster will turn on.
For more information, please
check Chapter 5. ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a
moderate rate and maintain a
steady cruising speed. Do not
make "jack-rabbit" starts. Do not
race between stoplights.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
The regenerative brake generates energy when the vehicle deceler-
ates.
When the hybrid battery power is low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine is running with the shift lever in N (Neutral), the
hybrid system cannot generate
electricity. The hybrid battery can-
not recharge with the shift lever in N
(Neutral).
Information
In the hybrid system, the engine auto-
matically runs and stops. When the
hybrid system operates, the " "
indicator is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is beingcharged
- Depending on the temperature con- dition of the hybrid battery
