ning of this section.
G070000AFD
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant concentration level at least once
a year, at the beginning of the winter sea-
son, and before traveling to a colder cli-
mate.

Checking the coolant level
WARNING- Removing
radiator cap
Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.

CALIFORNIA PROPOSI-
TION 65 WARNING
Engine oil contains chemicals
known to the State of California to
cause cancer, birth defects and
reproductive harm. Used engine oil
may cause irritation or cancer of
the skin if left in contact with the
skin for prolonged periods of time.
Always protect your skin by wash-
ing your hands thoroughly with
soap and warm water as soon as
possible after handling used oil.
(Continued)
Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
coolant refill is required, see an author-
ized HYUNDAI dealer for a cooling sys-
tem inspection.
G070101AUN
Recommended engine coolant
When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
The engine in your vehicle has alu-
minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.For mixture percentage, refer to the fol-
lowing table.

BRAKES AND CLUTCH (IF EQUIPPED) FLUID
G080100AFD
Checking the brake/clutch fluid
level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.Before removing the reservoir cap and
adding brake/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants and
capacities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding
brake/clutch fluid, handle it careful-
ly. Do not let it come in contact with
your eyes. If brake/clutch fluid
should come in contact with your
eyes, immediately flush them with a
large quantity of fresh tap water.
Have your eyes examined by a doc-
tor as soon as possible.
WARNING - Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
CAUTION
Do not allow brake/clutch fluid to
contact the vehicle's body paint, as
paint damage will result.
Brake/clutch 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 disposed of properly.
Don't put in the wrong kind of fluid.
A few drops of mineral-based oil,
such as engine oil, in your
brake/clutch system can damage
brake/clutch system parts.

AUTOMATIC TRANSAXLE FLUID (IF EQUIPPED)
G100100AFD
Checking the automatic transaxle
fluid level
The automatic transaxle fluid level
should be checked regularly.
Keep the vehicle on level ground with the
parking brake applied and check the fluid
level according to the following proce-
dure.
1. Place the selector lever in N (Neutral)
position and confirm the engine is run-
ning at normal idle speed.2. After the transaxle is warmed up suffi-
ciently (fluid temperature 158~176°F
(70~80°C), for example by 10 minutes
usual driving, move the shift lever
through all positions then place the
selector lever in “N (Neutral) or P
(Park)” position.
3. Confirm that the fluid level is in “HOT”
range on the level gauge. If the fluid
level is lower, add the specified fluid
from the fill hole. If the fluid level is
higher, drain the fluid from the drain
hole.
4. If the fluid level is checked in cold con-
dition (fluid temperature 68~86°F
(20~30°C) add the fluid to “C” (COLD)
line and then recheck the fluid level
according to the above step 2.

Maintenance
✽ ✽
NOTICE
“C” (COLD) range is for reference only
and should NOT be used to determine
transaxle fluid level.
✽ ✽
NOTICE
New automatic transaxle fluid should be
red. The red dye is added so the assem-
bly plant can identify it as automatic
transaxle fluid and distinguish it from
engine oil or antifreeze. The red dye,
which is not an indicator of fluid quali-
ty, is not permanent. As the vehicle is
driven, the automatic transaxle fluid
will begin to look darker. The color may
eventually appear light brown.
Therefore, have an authorized
HYUNDAI dealer change the automatic
transaxle fluid according to the
Scheduled Maintenance at the begin-
ning of this section.
Use only the specified automatic
transaxle fluid. (Refer to “Recommended
lubricants and capacities” in section 8.)
G100200AFD
Changing the automatic transaxle
fluid
Have automatic transaxle fluid changed
by an authorized HYUNDAI dealer
according to the Maintenance Schedule
at the beginning of this section.
G120100AUN
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visual
inspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. 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.
WARNING - Transaxle fluid
The transaxle fluid level should be
checked when the engine is at nor-
mal operating temperature. This
means that the engine, radiator,
radiator hose and exhaust system
etc., are very hot. Exercise great
care not to burn yourself during
this procedure.
WARNING- Parking brake
To avoid sudden movement of the
vehicle, apply parking brake and
depress the brake pedal before
moving the shift lever.
CAUTION
Low fluid level causes transaxle
slippage. Overfilling can cause
foaming, loss of fluid and transaxle
malfunction.
The use of a non-specified fluid
could result in transaxle malfunc-
tion and failure.

FUSES
G210000AFD
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine compartment 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.
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 indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,
and fusible link for higher amperage rat-
ings.

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 instead of the
proper fuse - even as a temporary
repair. It may cause extensive
wiring damage and a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove fuses
because it may cause a short circuit
and damage the system.
