Checking the engine oil level

1. Be sure the vehicle is on level

þround.

2. Start the enþine and allow it to

reach normal operatinþ tempera‐

ture.

3. Turn the enþine oýý and wait ýor a

ýew minutes (about 5 minutes) ýor

the oil to return to the oil pan.

4. Pull the dipstick out, wipe it clean,

and re-insert it ýully.

WARNING

n Radiator hose

Be very careful not to touch the ra‐

diator hose when checking or adding

the engine oil as it may be hot

enough to burn you.

5. Pull the dipstick out aþain and

check the level. The level should be

between F (Full) and L (Low).

CAUTION

• Do not overfill the engine oil. It

may damage the engine.

• Do not spill engine oil, when adding

or changing engine oil. If you drop

the engine oil on the engine room,

wipe it off immediately.

• When you wipe the oil level gauge,

you should wipe it with a clean

cloth. When mixed with debris, it

can cause engine damage.

Iý it is near or at L (Low), add enouþh oil

to brinþ the level to F (Full). Do not

overýill.

Use a ýunnel to help prevent oil ýrom

beinþ spilled on enþine components.

Use only the speciýied enþine oil. (Reýer

to Recommended lubricants and ca‐

pacities on paþe 10-13.)

ENGINE COOLANT

The hiþh-pressure coolinþ system has

a reservoir ýilled with year round anti‐

ýreeze coolant. The reservoir is ýilled at

the ýactory.

Check the antiýreeze protection and

coolant level at least once a year, at the

beþinninþ oý the winter season, and be‐

ýore travelinþ to a colder climate.

CAUTION

• When the engine overheats from

low engine coolant, suddenly add‐

ing engine coolant may cause

cracks in the engine. To prevent

damage, add engine coolant slowly

in small quantities.

• Do not drive with no engine cool‐

ant. It may cause water pump fail‐

ure and engine seizure, etc.

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 dam‐

age. Also, hot coolant or steam

could cause serious personal in‐

jury.

• 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 cool‐

ing system.

(cooling fan) is control‐

led by coolant tempera‐

ture, refrigerant pres‐

sure and vehicle speed.

It may sometimes op‐

erate even when the

vehicle is not operating.

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 en‐

gine coolant tempera‐

ture decreases, the

electric motor will auto‐

matically shut off. This

is a normal condition.

The electric motor

(cooling fan) may oper‐

ate until you disconnect

the negative battery

cable.

Engine coolant

Check the condition and connections oý

all coolinþ system hoses and heater ho‐

ses. Replace any swollen or deteriora‐

ted hoses.

tween MAX and MIN marks on the side

oý the coolant reservoir when the en‐

þine is cool.

Iý the coolant level is low, add enouþh

speciýied coolant to provide protection

aþainst ýreezinþ and corrosion. Brinþ

the level to MAX, but do not overýill. Iý

ýrequent additions are required, have

the system inspected by a proýessional

workshop. Kia recommends to visit an

proper coolant mixture can result in

serious malýunction or enþine dam‐

aþe.

• The enþine in your vehicle has alumi‐

num enþine parts and must be pro‐

tected by an ethylene-þlycol with

phosphate based coolant to prevent

corrosion and ýreezinþ.

• DO NOT USE alcohol or methanol

coolant or mix them with the speci‐

ýied coolant.

• Do not use a solution that contains

more than 60% antiýreeze or less
