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.

WARNING
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.

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.

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.

Maintenance
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.

Specifications4 9Recommended lubricants and capacities To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in improved fuel economy.These lubricants and fluids are recommended for use in your vehicle.*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing the amount of fuel nec-
essary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s time, they can offer significant cost and
energy savings.Lubricant Volume Classification

Specifications
Recommended SAE viscosity
number
Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operation (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and cold
weather performance, however, higher
viscosity engine oils are required for sat-
isfactory lubrication in hot weather. Using
oils of any viscosity other than those rec-
ommended could result in engine dam-
age.When choosing an oil, consider the range
of temperature your vehicle will be oper-
ated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or drain-
ing any lubricant. This is especially
important in dusty or sandy areas
and when the vehicle is used on
unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine
and other mechanisms that could
be damaged.

1. For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-
20,5W-30 (API SJ, SL / ILSAC GF-3 or above). However, if the engine oil is not available in
your country, select the proper engine oil using the engine oil viscosity chart.
