What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine will probably be
too hot. If this happens, you should:
1.Pull off the road and stop as soonas it is safe to do so.
2.Place the shift lever in P (for Automatic transmission / Dual
clutch transmission) and set the
parking brake. If the air condition-
ing is on, turn it off.
3.If engine coolant is running out under the vehicle or steam is com-
ing out from underneath the hood,
stop the engine. Do not open the
hood until the coolant has stopped
running or the steaming has
stopped. If there is no visible loss
of engine coolant and no steam,
leave the engine running and
check to be sure the engine cool-
ing fan is operating. If the fan is not
running, turn the engine off. 4.Check to see if the water pump
drive belt is missing. If it is not
missing, check to see that it is
tight. If the drive belt seems to be
satisfactory, check for coolant leak-
ing from the radiator, hoses or
under the vehicle. (If the air condi-
tioning had been in use, it is nor-
mal for cold water to be draining
from it when you stop).
5.If the water pump drive belt is bro- ken or engine coolant is leaking
out, stop the engine immediately
and call the nearest authorized Kia
dealer for assistance. 6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. If coolant has been lost, care-
fully add coolant to the reservoir 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 overheating happens again,
call an authorized Kia dealer for
assistance.
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized Kia
dealer.
WARNING - Under the hood
While the engine is running, keep hair,
hands and clothing
away from moving
parts such as the fan
and drive belts to pre-
vent injury.
WARNING - Radiator cap
Do not remove the
radiator cap when the
engine is hot. This may
result in coolant being
blown out of the open-
ing and cause serious
burns.

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
road.
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 transmis- sion/dual clutch 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.
