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
Serious loss of coolant indicates
there is a leak in the cooling system
and should be checked as soon as
possible by an authorized Kia dealer.
CAUTION
When the engine overheats from
low engine coolant, suddenlyadding engine coolant maycause cracks in the engine. Toprevent damage, add enginecoolant slowly in small quantities
WARNING
Do not remove the
radiator cap when the
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 6 mm (0.24 in).
Please contact the nearest Kia
dealership if the tire cannot be
made roadworthy with the Tire
Mobility Kit.
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 use the Tire Mobility Kit if the ambient temperature is below -30°C
(-22°F).
WARNING
• If sealant comes into contactwith skin, wash the affected
areas thoroughly. Seek med-
ical attention if irritation
develops and persists.
If sealant comes into contact with the eyes, flush eyes with
water for at least 15 minutes.
Seek medical attention if irri-
tation persists.
If sealant is swallowed, call a physician or poison control
center immediately.
WARNING
Do not use the Tire Mobility Kit
if a tire is severely damaged.
WARNING
Exposure to the sealant for a
long time may cause damage to
the body.
WARNING
Do not leave the compressor
running for more than 10 min. at
a time or it may overheat.

9. Connect between compressor and
the vehicle power outlet using the
cable and connectors (4).
✽ ✽NOTICE
Only use the front passenger side
power outlet.
10. With the engine start/stop button
position on: switch on the com-
pressor and let it run for approxi-
mately 5~7 minutes to fill the
sealant up to proper pressure
(refer to the "Tires and wheels" in
chapter 9). Be careful not to overinflate the
tire and stay away from the tire
when filling it. When the tire and
wheel are damaged, do not use
Tire Mobility Kit for your safety.
11. Switch off the compressor.
12. Detach the hose from the sealant bottle connector and from the tire
valve.
Return the Tire Mobility Kit to its stor-
age location in the vehicle.
Distributing the sealant
13. Immediately drive approximately 7 ~ 10 km (4 ~ 6 miles or, about
10 min) to evenly distribute the
sealant in the tire.

WARNING
Do not attempt to drive your
vehicle if the tire pressure is
below 200 kPa (29 psi). This
could result in an accident due
to sudden tire failure.
WARNING
Carbon monoxide poisoning
and suffocation is possible if the
engine is left running in a poorly
ventilated or unventilated loca-
tion (such as inside a building).
CAUTION
When you use the Tire MobilityKit, the tire pressure sensorsand wheel may be stained bysealant. Therefore, remove thetire pressure sensors and wheelstained by sealant and haveyour vehicle inspected by anauthorized Kia dealer.

Owner maintenance precau-
tions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section,
several procedures can be done only
by an authorized Kia dealer with spe-
cial tools.
✽ ✽NOTICE
Improper owner maintenance dur-
ing the warranty period may affect
warranty coverage. For details, read
the separate Warranty & Consumer
Information manual provided with
the vehicle. If you're unsure about
any servicing or maintenance proce-
dure, have it done by an authorized
Kia dealer.
WARNING- Maintenance
work
Do not wear jewelry or loose
clothing while working under
the hood of your vehicle with
the engine running. These items
can become entangled in mov-
ing parts, if you must run the
engine while working under the
hood, make certain that you
remove all jewelry (especially
rings, bracelets, watches, and
necklaces) and all neckties,
scarves, and similar loose
clothing before getting near the
engine or cooling fans.WARNING- Touching metal parts
Do not touch metal parts
(including strut bars) while the
engine is operating or hot.
Doing so could result in serious
bodily injury. Turn the engine off
and wait until the metal parts
cool down to perform any main-
tenance work on the vehicle.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized Kia dealer at the frequencies
indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, level
roads.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING- Hot coolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure.
WARNING
When you open the engine
hood, turn the Hybrid system
off. If not, it may result in death
or serious injury because of the
high voltage flow.

77
Maintenance
At least monthly:
Check the coolant level in theengine coolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year (i.e., every Spring and Fall) :
Check the radiator, heater and air conditioning hoses for leaks or
damage.
Check the windshield washer spray and wiper operation. Clean
the wiper blades with clean cloth
dampened with washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
At least once a year :
Clean the body and door drainholes.
Lubricate the door hinges and check the hood hinges.
Lubricate the door and hood locks and latches.
Lubricate the door rubber weather- strips.
Check the air conditioning system.
Inspect and lubricate automatic transmission linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.
