G051300AUN
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
G051400AUN
Automatic transaxle fluid (if equipped)
The fluid level should be in the "HOT"
range of the dipstick, after the engine
and transaxle are at normal operating
temperature. Check the automatic
transaxle fluid level with the engine run-
ning and the transaxle in neutral, with the
parking brake properly applied.
G051500AUN Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.G051600AUN Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4specification.
G051700AUN
Parking brake
Inspect the parking brake system includ-
ing the parking brake lever and cables.
G051900AUN
Brake pads, calipers and rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
G052100AUN Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.G052200AUN
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine off,
check for excessive free-play in the
steering wheel.
Check the linkage for bends or damage.
Check the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
G052400AUN Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.

BRAKE AND CLUTCH (IF EQUIPPED) FLUID
G080100AFD-EA
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 autho-
rised HYUNDAI dealer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants andcapacities” in 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 authorised 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 extendedtime should never be used as itsquality 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 brakeclutch system can damage brake
clutch system parts.

AUTOMATIC TRANSAXLE FLUID (IF EQUIPPED)
G100100AFD-EA
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 leverthrough 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 “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 determinetransaxle 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 isdriven, the automatic transaxle fluid
will begin to look darker. The colour
may eventually appear light brown.
Therefore, have an authorised
HYUNDAI dealer change the automatictransaxle fluid according to theScheduled Maintenance at the begin-ning of this section.
Use only the specified automatic
transaxle fluid. (Refer to “Recommended
lubricants and capacities” in section 9.) G100200AFD-EA Changing the automatic transaxle fluid
Have automatic transaxle fluid changed
by an authorised HYUNDAI dealeraccording to the Maintenance Scheduleat 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 causefoaming, loss of fluid and transaxle malfunction.
The use of a non-specified fluid could result in transaxle malfunc-tion and failure.
