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.

For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired
while defrosting or defogging, set
the mode to the floor-defrost posi-
tion.
Before driving, clear all snow and
ice from the windshield, rear win-
dow, outside rear view mirrors, and
all side windows.
Clear all snow and ice from the
hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probabili-
ty of fogging up the inside of the
windshield.Automatic climate control
system
To defog inside windshield
1. Set the fan speed to the desired
position.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The outside (fresh) air position will
be selected automatically and the
air conditioning will turn on accord-
ing to the detected ambient tem-
perature.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - Windshield
heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and the
windshield could cause the
outer surface of the windshield
to fog up, causing loss of visi-
bility. If this occurs, set the
mode selection to the posi-
tion and fan speed control to
the lower speed.

Automatic climate control system
1. Turn the ignition switch to the ON
position.
2. Press the defroster button ( ).
3. While pressing the air conditioning
button (A/C), press the air intake
control button at least 5 times with-
in 3 seconds.
The recirculation indicator blinks 3
times with 0.5 second of interval. It
indicates that the defogging logic is
canceled or returned to the pro-
grammed status.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.
Auto defogging system
Auto defogging reduces the probabil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture of inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.This indicator illuminates
when the auto defogging
system senses the mois-
ture on the inside of the
windshield and operates.
If more moisture is in the vehicle,
higher steps operate as follow. For
example if auto defogging does not
defog inside the windshield at step 1
Outside air position, it tries to defog
again at step 2 Operating the air con-
ditioning.
Step 1 : Outside air position
Step 2 : Operating the air condition-
ing
Step 3 : Blowing air flow toward the
windshield
Step 4 : Increasing air flow toward
the windshield

Driving your vehicle

Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle may also pull to one side when
the brakes are applied. Applying the
brakes lightly will indicate whether
they have been affected in this way.
Always test your brakes in this fash-
ion after driving through deep water.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
✽ ✽
NOTICE
Do not depress the brake pedal con-
tinuously without the “ ” indica-
tor ON. The battery may be dis-
charged.
In the event of brake failure
If service brakes fail to operate while
the vehicle is in motion, you can
make an emergency stop with the
parking brake. The stopping dis-
tance, however, will be much greater
than normal.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high-pitched warning sound from
your front brakes or rear brakes. You
may hear this sound come and go or
it may occur whenever you depress
the brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
Always replace the front or rear
brake pads as pairs.
WARNING- Parking
brake
Avoid applying the parking
brake to stop the vehicle while it
is moving except in an emer-
gency situation. Applying the
parking brake while the vehicle
is moving at normal speeds can
cause a sudden loss of control
of the vehicle. If you must use
the parking brake to stop the
vehicle, use great caution in
applying the brake.
CAUTION- Replace brake
pads
Do not continue to drive with
worn brake pads. Continuing to
drive with worn brake pads can
damage the braking system and
result in costly brake repairs.

As explained above, if the vehicle
cannot be started after pressing the
“12V Batt Reset” switch (1) due to
over discharge, try to jump-start
(refer to Jump-starting).Charging method for 12V battery
(A) It is recommended to charge the
12V battery by starting and run-
ning the vehicle (HEV Ready
Mode) for a minimum of 30 min-
utes if a 12V reset, or jump start
has been used.
(B) If you cannot start the vehicle :
After connecting the jumper cables
at the recommended locations, you
should press “12V batt Reset”
switch (1) to charge the battery.
The voltage range of the charger
should be 13.3~14V and its current
range should be less than 60A.
(13.8V is recommended).CAUTION
• The use of an improper charg-
er with a voltage and current
range higher than specified
may cause overheating and
damage to the 12V battery.
The use of an incorrect charg-
er will lead to a power shut-off
to save the 12V battery. Stop
using the incorrect charger
once the power of the vehicle
is shut off.

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.

CLIMATE CONTROL AIR FILTER (IF EQUIPPED)
Filter inspection
The climate control air filter should
be replaced according to the
Maintenance Schedule. If the vehicle
is operated in severely air-polluted
cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
1. Open the glove box and remove
the stoppers on both sides.2. With the glove box open, pull the
support strap (1).
