Features of your vehicle
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 electric power steering is con-
trolled by a power steering control
unit which senses the steering wheel
torque and vehicle speed to com-
mand 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. 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 ignition
switch on. This happens as the sys-
tem performs the EPS system
diagnostics. When the diagnostics
are completed, the steering wheel
will return to its normal condition.
• A click noise may be heard from the EPS relay after the ignition
switch is turned to the ON or
LOCK (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)

Engine Coolant Temperature
Gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is ON.
If the gauge pointer moves beyond
the normal range area toward the “H”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “If the Engine
Overheats” in chapter 6.
Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.OJF048134L
WARNING - Hot radiator
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could cause severe
burns. Wait until the engine is
cool before adding coolant to
the reservoir.

If the warning light stays on while the
engine is running, it indicates that
there may be serious engine dam-
age or malfunction. In this case,
1. Stop the vehicle as soon as it is
safe to do so.
2. Turn off the engine and check the oil level. If the oil level is low, fill the
engine oil to the proper level.
3. Start the engine again. If the warn- ing light stays on after the engine
is started, turn the engine off
immediately. In this case, have
your vehicle inspected by an
authorized Kia dealer.Low Tire Pressure
Warning Light
This warning light illuminates:
Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds and then goes off.
When one or more of your tires are significantly underinflated.
❈ For more details, refer to “Tire
Pressure Monitoring System
(TPMS)” in chapter 6.
This warning light remains on after
blinking for approximately 60 seconds
or repeats blinking on and off at the
intervals of approximately 3 seconds:
When there is a malfunction with the TPMS.
In this case, have your vehicle
inspected by an authorized Kia
dealer as soon as possible.
❈ For more details, refer to “Tire
Pressure Monitoring System
(TPMS)” in chapter 6.
CAUTION - Engine
damage
If the engine is not stopped
immediately after the engine oilpressure warning light is illumi-nated and stays on while theengine is running, seriousengine damage may result.
CAUTION - Engine
Overheating
Do not continue driving with theengine overheated. Otherwise,the engine may be damaged.

Fan speed control
The ignition switch must be in the ON
position for fan operation.
The fan speed control knob allows
you to control the fan speed of the air
flowing from the ventilation system.
To change the fan speed, turn the
knob to the right for higher speed or
left for lower speed.
Setting the fan speed control knob to
the “0” position turns off the fan.
Air conditioning
Press the A/C button to turn the air
conditioning system on (indicator
light will illuminate). Press the button
again to turn the air conditioning sys-
tem off.
WARNING- Sleeping with
A/C on
Do not sleep in a vehicle with
the air conditioning or heating
system on as this may cause
serious harm or death due to a
drop in the oxygen level and/or
body temperature.
WARNING- Recirculated
air
Continued use of the climate
control system in the recirculat-
ed air position can cause
drowsiness or sleepiness, and
loss of vehicle control. Set the
air intake control to the outside
(fresh) air position as much as
possible while driving.

If the windshield fogs up, set the mode to the or position. 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
Kia Air Conditioning Systems are
filled with R-1234yf refrigerant.
1.Start the engine. Push the air con-ditioning 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.
The refrigerant system should only be serviced by trained and certified
technicians to insure proper and
safe operation.
The refrigerant system should be serviced in a well-ventilated place.
The air conditioning evaporator (cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators
should be certified (and labeled) as
meeting SAE Standard J2842.

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
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.
