VEHICLE MAINTENANCE REQUIREMENTS8
F070G02A-AATo Brake FluidCheck 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 4.F070F01A-AATo Brake Hoses and LinesVisually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
F070E06A-AATo Automatic Transaxle FluidThe 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 running
and the transaxle in neutral, with the
parking brake properly applied. Use
HYUNDAI GENUINE ATF SP III, DIAMOND
ATF SP III, SK ATF SP III or other brands
meeting the SP III specification approved
by Hyundai Motor Co. when adding or
changing fluid. Using the wrong ATF may
result in damage to the ATM.

Parking BrakeCheck the rear brake drums and linings for
scoring, burning, leaking fluid, broken parts,
and excessive wear. Inspect the parking
brake system including the parking brake
lever and cables. For detailed service
procedures, refer to the Shop Manual.

API SJ, SL or ABOVE,
ILSAC GF-3 or ABOVE
G030B01JM-U G030A01A-AAT
Engine oil is essential to the performance
and service of the engine. It is suggested
that you check the oil level at least once a
week in normal use and more often if you
are on a trip or driving in severe conditions.

G050B01A-AATRecommended Engine CoolantUse a high quality ethylene-glycol coolant
in a 50/50 mix with water. The engine
coolant should be compatible with
aluminum engine parts. Additional
corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration
and type of engine coolant to prevent
freezing and corrosion. Never allow the
concentration of antifreeze to exceed the
60% level or go below the 35% level, or
damage to the cooling system may result.
For proper concentration when adding or
replacing the engine coolant, refer to the
following table.
G050C01NF-GATTo Check the Coolant LevelThe coolant level can be seen on the side
of the plastic coolant reservoir. The level of
the coolant should be between the "L" and
"F" lines on the reservoir when the engine
is warm with it at idle . If the level is below
the "L" mark, add engine coolant to bring
it up to "F". If the level is low, inspect for
coolant leaks and recheck the fluid level
frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
diagnosis of the reason.
G050C01NFG050D01NF-GAT
To Change the Engine CoolantThe engine coolant should be changed at
those intervals specified in the vehicle
maintenance schedule in Section 5.
CAUTION:
o Engine coolant can damage the finish
of your car. If you spill engine coolant
on the car, wash it off thoroughly with
clean water.
o The engine in your vehicle has alumi-
num engine parts and must be
protected by an ethylene-glycol base
coolant to prevent corrosion and freez-
ing.
Do not use hard water. Hard water can
cause engine damage from corro-
sion, overheating or freezing.

2. After the transaxle is warmed up
sufficiently (fluid temperature 70~80°C
(158~176°F), 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.
G110D03O-AATChecking the automatic transaxle
fluid levelThe 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
procedure.
1. Place the selector lever in N (Neutral)
position and confirm the engine is
running at normal idle speed.
ONF078008
OHD076045N
Fluid level should be within "HOT" range
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
condition (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.
