ENGINE OIL
G060100CEN
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal operating temperature.
3. Turn the engine off and wait for a few
minutes (about 5 minutes) for the oil to
return to the oil pan.
4. Pull the dipstick out, wipe it clean, and
re-insert it fully.5. Pull the dipstick out again and check
the level. The level should be between
F and L.
If it is near or at L, add enough oil to bring
the level to F.Do not overfill.
Use a funnel to help prevent oil from
being spilled on engine components.
Use only the specified engine oil. (Refer
to “Recommended lubricants and capaci-
ties” in section 9.)
WARNING - Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may be
hot enough to burn you.
OTQ077002LOTQ077003L
CAUTION - Diesel engine
Overfilling the engine oil may cause
severe dieseling due to churning
effect. It may lead to engine damage
accompanied with abrupt engine
speed increment, combustion noise
and white smoke emission.
CAUTION
• Do not overfill with engine oil.
Engine damage may result.
• Do not spill engine oil, when
adding or changing engine oil. If
you drop the engine oil on the
engine room, wipe it off immedi-
ately.

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.
• 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.
(Continued)CAUTION
• Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.

727
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 is
cool.
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, we recommend
that the system be inspected by an
authorized HYUNDAI dealer.
G070101BUN
Recommended engine coolant
• When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
• 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 specified
coolant.
• 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.
WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate even
when the engine is not running.
Use extreme caution when working
near the blades of the cooling fan
so that you are not injured by a
rotating fan blades. As the engine
coolant temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
(Continued)
• 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.

BRAKE/CLUTCH FLUID (IF EQUIPPED)
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 nor-
mal condition associated with the wear of
the brake linings. If the fluid level is
excessively low, we recommend that the
system be checked by an authorized
HYUNDAI dealer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants and
capacities” in section 8.)
Never mix different types of fluid.
✽NOTICE
Before removing the brake/clutch filter
cap, read the warning on the cap.
OTQ074006
WARNING- Loss of
brake/clutch fluid
In the event the brake/clutch sys-
tem requires frequent additions of
fluid, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.
WARNING- Brake/ clutch
fluid
When changing and adding brake/
clutch fluid, handle it carefully. 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 doctor as
soon as possible.
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.
WARNING
Clean filler cap before removing.
Use only DOT3 or DOT4 brake/clutch
fluid from a sealed container.

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 reservoir at the normal tem-
perature.
Before adding power steering fluid, thor-
oughly clean the area around the reser-
voir cap to prevent power steering fluid
contamination.
If the level is low, add fluid to the MAX
level.
✽NOTICE
Check that the fluid level is in the
"HOT" range on the reservoir. If the
fluid is cold, check that it is in the
"COLD" range.
In the event the power steering system
requires frequent additions of fluid, we
recommend that the system be inspect-
ed by an authorized HYUNDAI dealer.
Use only the specified power steering
fluid. (Refer to "Recommended lubricants
or capacities" in section 9.)
G090200AEN
Checking the power steering
hose
Check the connections for oil leaks, dam-
age and twists in the power steering
hose before driving.
OTQ077007CAUTION
• To avoid damage to the power
steering pump, do not operate the
vehicle for prolonged periods
with a low power steering fluid
level.
• Never start the engine when the
reservoir tank is empty.
• When adding fluid, be careful that
dirt does not get into the reser-
voir.
• Too little fluid can result in
increased steering effort and/or
noise from the power steering
system.
• The use of the non-specified fluid
could reduce the effectiveness of
the power steering system and
cause damage to it.
