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 level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.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.
(Continued)
(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.

Maintenance
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
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
additions are required, see an authorized
Hyundai dealer for a cooling system
inspection.
Recommended engine coolant Use only soft (de-mineralized) water in
the coolant mixture.
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.

Maintenance
BRAKES AND CLUTCH (IF EQUIPPED) FLUIDChecking 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 the section 9.)
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.
OHD076011
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.

Maintenance20 7AUTOMATIC TRANSAXLE FLUID (IF EQUIPPED)Checking the automatic transaxle
fluid level The automatic transaxle fluid level
should be checked regularly.
Keep the vehicle on the level ground with
the parking brake applied and check the
fluid level according to the following pro-
cedure.
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 70~80°C
(158~176°F), for example by 10 min-
utes 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 20~30°C
(68~86°F) add the fluid to “COLD” line
and then recheck the fluid level
according to the above step 2.

Maintenance
✽ ✽
NOTICE“COLD” range is for reference only and
should NOT be used to determine
transaxle fluid level.
✽ ✽
NOTICENew 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 beginning of this
section.Use only the specified automatic
transaxle fluid. (Refer to the section 9.)Changing the automatic transaxle
fluidHave automatic transaxle fluid changed
by an authorized Hyundai dealer accord-
ing to the Maintenance Schedule at the
beginning of this section.
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.

Maintenance24 7Replace the filter according to the
Scheduled Maintenance Section.If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-
ment more often than the usual recom-
mended intervals. (Refer to
“Maintenance under severe usage condi-
tions” in this section.)
CAUTION
Do not drive with the air cleaner
removed; this will result in exces-
sive engine wear.
When removing the air cleaner fil-
ter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
Use a Hyundai genuine part. Use
of nongenuine parts could dam-
age the air flow sensor.

Maintenance30 7
Battery recharging Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in a
short time (because, for example, the
headlights 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 electric load while the
vehicle is being used, recharge it at 20-
30A for two hours.
Reset itemsItems should be reset after the battery
has been discharged or the battery has
been disconnected.
