Maintenance
Recommended engine coolant
• When adding coolant, use only
deionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
• The engine in your vehicle has alu-
minum engine parts and must de
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
solution.
For mixture percentage, refer to the
following table.

to visit an authorised Kia dealer/serv-
ice partner.
