Checking the engine oil level
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on level ground.
3. Start the engine and allow it to reach normal operating temperature.
4. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
5. Pull the dipstick out, wipe it clean, and re-insert it fully. 6. Pull the dipstick out again and
check the level. The level should
be between F (Full) and L (Low). 7. If it is near or at L, add enough oil
to bring the level to F.
Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” in chapter 8.)

Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding engine oil as it may be
hot enough to burn you.
WARNING

MaintenanceThe electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.
WARNING
Never remove the
coolant cap/radiator
cap or the drain plug
while the engine and
radiator are hot. Hot
coolant and steam may blow out
under pressure, causing serious
injury.
Turn the engine off and wait until
the engine cools down. Use
extreme care when removing the
coolant cap/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.

Maintenance
Recommended engine coolant
When adding coolant, use only dis-tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory. An
improper coolant mixture can
result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the solu-
tion. For mixture percentage, refer to the
following table.
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
Changing the engine coolant
We recommend that coolant be
changed by an authorized HYUNDAI
dealer according to the Maintenance
Schedule at the beginning of this
chapter.
To prevent damage to engine parts,
put a thick towel around the radia-
tor cap and/or radiator cap before
refilling the coolant to prevent the
coolant from overflowing into
engine parts, such as the genera-
tor.
