6. If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheat-
ing. If over heating happens again,
call the nearest authorized Kia
dealer for assistance.
✽ ✽NOTICE

there is a leak in the cooling system
and should be checked as soon as
possible by an authorized Kia dealer.

engine is hot. This
can allow coolant to
blow out of the open-
ing and cause seri-
ous burns.

Use of the Tire Mobility Kit may not
be effective for tire damage larger
than approximately 0.24 in (6 mm).
Please contact the nearest Kia
dealership if the tire cannot be
made roadworthy with the Tire
Mobility Kit.
Do not use the Tire Mobility Kit if a tire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave the engine running. Otherwise
operating the compressor may
eventually drain the car battery. Never leave the Tire Mobility Kit
unattended while it is being used.
Do not leave the compressor run- ning for more than 10 min. at a time
or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below -22°F
(-30°C).
If the sealant gets on your skin, wash it with a large amount of
water and if it irritates continuously,
visit a doctor for examination.
If the sealant gets into your eyes, raise your eyelid and wash for at
least 15 minutes. If it irritates con-
tinuously, visit a doctor for exami-
nation.
If you have drank the sealant, wash the mouth and drink a large amount
of water. However, do not give any-
thing to an unconscious person and
see the doctor immediately.
Exposure to the sealant for a long
time may cause damage to the
bodily tissues.
