Features of your vehicle

When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic.
Operating the air conditioning sys- tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.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 every 15,000
miles or once a year.
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.

(For Hybrid)When the vehicle is under regular
maintenance, make sure to separate
the (-) cable inside the luggage room
before maintenance.
Procedures to separate the (-) cable
is as below :
Fold the rear left side seat.
Using the key or (-) screwdriver,remove the service cover (A) on
the luggage trim.
Separate the (-) cable (B). Reassemble in the reverse order of
disassembly.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-
