G060200AEN Changing the engine oil and filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according tothe Maintenance Schedule at the begin-ning of this section. G070000AUN 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 thebeginning of the winter season, and
before traveling to a colder climate. G070100AEN
Checking the coolant level
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 thoroughlywith soap and warm water as soon
as possible after handling used oil.
ENGINE COOLANT
WARNING - Removing
radiator cap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might leadto 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 untilit 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 aresure 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 radiatorcap 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.

Maintenance
Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine iscool.If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
HYUNDAI dealer for a cooling systeminspection.
G070101AUN
Recommended engine coolant
Use only soft (de-mineralized) water in
the coolant mixture.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution. For mixture percentage, refer to the fol-
lowing table.

BRAKE AND CLUTCH (IF EQUIPPED) FLUID
G080100AUN
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 author-
ized HYUNDAI dealer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants orcapacities” in section 8.)
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.
OBK079007
CAUTION
Do not allow brake/clutch fluid to contact the vehicle's body paint, aspaint damage will result.Brake/clutch fluid, which has been exposed to open air for an extended
time 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 brake / clutch system can damage brake /clutch system parts.

POWER STEERING FLUID
G090100ABH
Checking the power steering fluid
level
With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the gauge at the normal tempera-
ture. Before adding power steering fluid, thor-oughly clean the area around the reser-
voir cap to prevent power steering fluidcontamination.
If the level is low, add fluid to the MAX
level.
✽✽
NOTICE - (if equipped)
Check that the fluid level is in the
"HOT" range on the gauge. If the fluid
is cold, check that it is in the "COLD"
range.
In the event the power steering system requires frequent addition of fluid, the
vehicle should be inspected by an
authorized HYUNDAI dealer.
Use only the specified power steering fluid. (Refer to "Recommended lubricants
or capacities" in section 8.)
G090200AEN
Checking the power steering hose
Check the connections for oil leaks, dam-
age and twists in the power steering
hose before driving.
CAUTION
To avoid damage to the power steering pump, do not operate the
vehicle for prolonged periods with a low power steering fluidlevel.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into the tank.
Too little fluid can result in increased steering effort and/ornoise from the power steering
system.
The use of the non-specified fluid could reduce the effectiveness ofthe power steering system andcause damage to it.
