Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, have the climate control air fil-
ter replaced by an authorized Kia
dealer.
✽ ✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized Kia
dealer.

What to do in an emergency
86
Jump starting
Connect cables in numerical order
and disconnect in reverse order.
Remove the air filter cover before
connecting the cable to part (4).
Jump starting can be dangerous if
done incorrectly. Therefore, to avoid
harm to yourself or damage to your
vehicle or battery, follow these jump
starting procedures. If in doubt, we
strongly recommend that you have a
competent technician or towing serv-
ice jump start your vehicle.
ODEP069002
CAUTION - Push/pull start
to 12 Volt Battery
Use only a 12-volt jumper sys- tem. You can damage a 12-voltstarting motor, ignition system,and other electrical partsbeyond repair by use of a 24-volt power supply (either two12-volt batteries in series or a24-volt motor generator set).
WARNING- Battery
Never attempt to check the elec-
trolyte level of the battery as
this may cause the battery to
rupture or explode.
WARNING- Frozen batteries
Do not attempt to jump start the
vehicle if the discharged battery
is frozen as the battery may
rupture or explode.
CAUTION - For hybrid
Do not jump start another vehi- cle with your hybrid vehicle.Jump starting another vehiclewill damage the hybrid vehicle's12 volt battery (lithium poly-mer type).

1: If TOP TIER Detergent Gasoline is not available, one bottle of additive is recommended. Additives are available from your authorized Kia dealer along with information on how to use them. Do not mix other additives.
*
2: Inspect HSG belt for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. If HSG belt noise occurred, readjust HSG belt tension before replace.
❈ As it is normal for engine oil to be consumed during driving, the amount of engine oil should be checked regularly.
❈ The replacement cycle of engine oil is set by the period which the performance of our recommended engine oil is maintained.
So, if recommended engine oil is not used, a replacement is required as in\
dicated severe usage condition.

Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
When assembling parts, be sure to
wipe the inside and outside of the
boot bottom of the ignition coil and
the insulator of the spark plug with a
soft cloth to prevent contamination of
the spark plug insulator.
Cooling system
Check the cooling system compo-
nents, such as the radiator, coolant
reservoir, hoses and connections for
leakage and damage. Replace any
damaged parts.
Coolant (Engine / Inverter)
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Dual clutch transmission Fluid
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.

AIR CLEANER
Filter replacement
The filter must be replaced when
necessary, and should not be
washed.
You can clean the filter when inspect-
ing the air cleaner element.
Clean the filter by using compressed
air.1. Loosen the air cleaner cover
attaching clips and open the cover.2. Wipe the inside of the air cleaner.
3. Replace the air cleaner filter.
4. Lock the cover with the cover
attaching clips.

Maintenance
Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extreme-
ly dusty or sandy areas, replace the
element more often than the usual
recommended intervals. (Refer to
“Maintenance under severe usage
conditions” in this chapter.)
CAUTION - Air filter
maintenance
Do not drive with the air clean-
er removed; this will result in
excessive engine wear.
When removing the air cleaner
filter, be careful that dust or
dirt does not enter the air
intake, or damage may result.
Use a Kia genuine part. Use of
a non-genuine part could
damage the air flow sensor.
