HYBRID STARTER & GENERATOR (HSG) BELT
Checking the hybrid starter &
generator (HSG) belt
We recommend that you have the
hybrid starter & generator (HSG)
belt inspected or replaced according
to the Maintenance Schedule in this
chapter by an authorized HYUNDAI
dealer.
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.
•Turn the vehicle off while you
inspect the engine or hybrid
starter & generator(HSG) belt.
Otherwise it may result in
serious injury.
•Keep hands, clothing etc.
away from the hybrid starter &
generator (HSG) belt.
WARNING
When the HSG belt is worn out or
damaged, replace the belt.
Otherwise, it may cause engine
overheating or battery discharge.
CAUTION

Maintenance
If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, we
recommend that the brake system
be checked by an authorized
HYUNDAI dealer.• Do not allow brake fluid to con-
tact the vehicle’s body paint, as
paint damage will result.
• Brake fluid, which has been
exposed to open air for an
extended time should NEVER be
used as its quality cannot be
guaranteed. It should be dis-
posed of properly.
• Do not use the wrong kind of
brake fluid. A few drops of miner-
al based oil, such as engine oil, in
your brake system can damage
brake system parts.
Information
Use only the specified brake fluid
Refer to “Recommended Lubricants
and Capacities” in chapter 8.
Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
i
NOTICE
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. We recommend
that the vehicle be inspected by
an authorized HYUNDAI dealer.
WARNING
Do not allow brake fluid to come
in contact with your eyes. If
brake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediate
medical attention.

Maintenance
Checking the parking brake
Foot type (if equipped)
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196 N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
have the parking brake adjusted by
an authorized HYUNDAI dealer.
Stroke : 4~5 notch
Filter replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.OAE056014
PARKING BRAKE
To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
•Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility
when sprayed on the wind-
shield and may cause loss of
vehicle control resulting in an
accident or damage to paint
and body trim.
•Do not allow sparks or flames
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain
alcohol and can be flamma-
ble.
•Do not drink washer fluid and
avoid contact with skin.
Washer fluid is poisonous to
humans and animals.
•Keep washer fluid away from
children and animals.

Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
over a short time (because, for
example, the headlamps or interior
lights were left on while the vehicle
was not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electrical load
while the vehicle is being used,
recharge it at 20-30A for two hours.Always follow these instructions
when recharging your vehicle’s
battery to avoid the risk of SERI-
OUS INJURY or DEATH from
explosions or acid burns:
•Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and place the Engine Start/
Stop button to the OFF posi-
tion.
•Keep all flames, sparks, or
smoking materials away from
the battery.
•Always work outdoors or in an
area with plenty of ventilation.
•Wear eye protection when
checking the battery during
charging.
•The battery must be removed
from the vehicle and placed in
a well ventilated area.

FUSES
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.
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 indi-
cates an electrical problem. Avoid
using the system involved and immedi-
ately consult an authorized HYUNDAI
dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.

Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.
CAUTION
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.

Maintenance
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
authorized 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 authorized 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 vehicle)
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, it must be
removed as follows:
1. Turn the vehicle off.
2. Disconnect the negative battery
cable.
3. Remove the fuse panel cover by
pressing the tab and pulling it up.
4. Remove the nuts shown in the pic-
ture above.
5. Replace the fuse with a new one
of the same rating.
6. Reinstall in the reverse order of
removal.
Information
If the multi fuse is blown, consult an
authorized HYUNDAI dealer.
