Electric power steering (EPS)
The power steering uses a motor to
assist you in steering the vehicle. If
the engine is off or if the power steer-
ing system becomes inoperative, the
vehicle may still be steered, but it will
require increased steering effort.
The motor driven power steering is
controlled by a power steering con-
trol unit which senses the steering
wheel torque and vehicle speed to
command the motor.
The steering becomes heavier as the
vehicle’s speed increases and
becomes lighter as the vehicle’s
speed decreases for optimum steer-
ing control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering checked by an authorized
Kia dealer. If the Electric Power Steering
System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steering
wheel may require increased
steering effort. Take your vehicle to
an authorized Kia dealer and have
the vehicle checked as soon as
possible.
When you operate the steering wheel in low temperature, noise
may occur. If temperature rises, the
noise will likely disappear. This is a
normal condition.
When the vehicle is stationary, and the steering wheel is turned all the
way to the left or right continuous-
ly, the steering wheel becomes
harder to turn. The power assist is
limited to protect the motor from
overheating.
As time passes, the steering wheel
will return to its normal condition.
✽ ✽ NOTICE
The following symptoms may occur
during normal vehicle operation:
• The EPS warning light does not
illuminate.
• The steering gets heavy immedi- ately after turning the Engine
Start/Stop button is ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics are complet-
ed, the steering wheel will return
to its normal condition.
• A click noise may be heard from the EPS relay after turning the
Engine Start/Stop button is ON or
OFF position.
• A motor noise may be heard when the vehicle is at a stop or at a low
driving speed.
• If the Electric Power Steering System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steer-
ing wheel may become difficult to
control or operate abnormally.
Take your vehicle to an authorized
Kia dealer and have the vehicle
checked as soon as possible. (Continued)

4.Set the fan speed control to the desired speed.
5.If dehumidified heating is desired, turn the air conditioning system (if
equipped) on.
If the windshield fogs up, set the mode to the
orposition. Operation Tips
To keep dust or unpleasant fumes
from entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Be sure to
return the control to the fresh air
position when the irritation has
passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
Air for the heating/cooling system is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
To prevent interior fog on the wind- shield, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to desired
temperature.
Air conditioning (if equipped)
All Kia Air Conditioning Systems are
filled with R-1234yf refrigerant.
1.Start the hybrid system. Press theair conditioning button.
2.Set the mode to the position.
3.Set the air intake control to the out- side air or recirculated air position.
4.Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired, set the temperature control to the
extreme left position, set the mode
control to the MAX A/C position,
then set the fan speed control to
the highest speed.

Air conditioning system operation tips
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system.
During air conditioning system operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance. 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.CAUTION - Excessive A/C
Use
When using the air conditioningsystem, monitor the tempera-ture gauge closely while drivingup hills or in heavy traffic whenoutside temperatures are high.Air conditioning system opera-tion may cause engine over-heating. Continue to use theblower fan but turn the air con-ditioning system off if the tem-perature gauge indicates engineoverheating.
CAUTION
When opening the windows inhumid weather, air conditioningmay create water dropletsinside the vehicle. Since exces-sive water droplets may causedamage to electrical equipment,air conditioning should only beused with the windows closed.
