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.

WARNING
- Recharging
battery
When recharging the battery,
observe the following precautions:
The battery must be removed
from the vehicle and placed in an
area with good ventilation.
Do not allow cigarettes, sparks,
or flame near the battery.
Watch the battery during charg-
ing, and stop or reduce the charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 120°F (49°C).
Wear eye protection when check-
ing the battery during charging.
(Continued)
(Continued)
Disconnect the battery charger in
the following order.
1. Turn off the battery charger main
switch.
2. Unhook the negative clamp from
the negative battery terminal.
3. Unhook the positive clamp from
the positive battery terminal.
WARNING
Before performing maintenance
or recharging the battery, turn off
all accessories and stop the
engine.
The negative battery cable must
be removed first and installed
last when the battery is discon-
nected.

Maintenance
FUSESA 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.

Maintenance46 7Inner panel fuse replacement1. Turn the ignition switch and all other
switches off.
2. Open the fuse panel cover.3. Pull the suspected fuse straight out.
Use the removal tool provided on the
main fuse box in the engine compart-
ment.
4. Check the removed fuse; replace it if it
is blown.
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.
If you do not have a spare, use a fuse of
the same rating from a circuit you may
not need for operating the vehicle, such
as the cigar lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse block in the engine
compartment. If a fuse is blown, it must
be replaced.
