Maintenance18 7Changing the coolantHave coolant changed by an authorized
Hyundai dealer according to the
Maintenance Schedule at the beginning
of this section.
WARNING -
Radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.
OHD076009
WARNING -
Coolant
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control or damage
to paint and body trim.
Windshield Washer fluid agents
contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
Windshield washer fluid is poi-
sonous to humans and animals.
Do not drink and avoid contact-
ing windshield washer fluid.
Serious injury or death could
occur.

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 thrown out. Don't put in
the wrong kind of fluid. A few drops
of mineral-based oil, such as
engine oil, in your brake clutch sys-
tem can damage brake clutch sys-
tem parts.

Maintenance20 7AUTOMATIC TRANSAXLE FLUID (IF EQUIPPED)Checking the automatic transaxle
fluid level The automatic transaxle fluid level
should be checked regularly.
The volume of the transaxle fluid
changes with temperature. Although it is
best to check the level after having driv-
en the vehicle for at least 30 minutes, the
level can be checked after warming the
fluid using the following procedure.1. Park the vehicle on level ground and
firmly apply the parking brake.
2. Allow the engine to idle for about 2
minutes.
3. Depress the brake pedal and move the
shift lever slowly through all ranges
then set it in P (Park) or N (Neutral).
4. With the engine still idling, pull out the
dipstick, wipe it clean and reinsert it
fully.
5. Pull out the dipstick again and check
the fluid level.
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.
OHD076012

721
Maintenance
If the fluid has been warmed to normal
operating temperature of approximately
158~176°F (70~80°C), the fluid level
should be within “HOT” range.✽ ✽
NOTICE“COLD (C)” 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.

Maintenance22 7WASHER FLUIDChecking 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.
Checking the parking brake Check the stroke of the parking brake by
counting the number of “clicks’’ heard
while fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, have the parking
brake adjusted by an authorized Hyundai
dealer.
Stroke : 7 “clicks’’ at a force of
44 lbs (20 kg, 196 N).

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 part could damage
the air flow sensor.

Maintenance
CLIMATE CONTROL AIR FILTERFilter inspectionThe climate control air filter should be
replaced every 10,000 miles (15,000
km). If the vehicle is operated in the
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you try to replace
the climate control air filter by owner
maintenance, replace it performing the
following procedure, and be careful to
avoid damaging other components.
Filter replacement1. Open the glove box and remove the
support rod.2. With the glove box open, remove the
stoppers on both sides to allow the
glove box hang freely on the hinges.
