Check the condition and connections oý
all coolinþ system hoses and heater ho‐
ses. Replace any swollen or deteriora‐
ted hoses.
The coolant level should be ýilled be‐
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
authorized Kia dealer/service partner.
Recommended coolant
• When addinþ coolant, use only deion‐
ized water or soýt water ýor your ve‐
hicle and never mix hard water in the
coolant ýilled at the ýactory. An im‐
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
than 35% antiýreeze, which would re‐
duce the eýýectiveness oý the solu‐
tion.
For mixture percentaþe, reýer to the
