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 EPS is controlled by a power
steering control unit which senses
the steering wheel torque and vehi-
cle 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 posi-
tion. This happens as the system
performs the EPS system diagnos-
tics. 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 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.

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
All Kia Air Conditioning Systems are
filled with R-1234yf refrigerant.
1.Start the engine. Press 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.
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.CAUTION - Excessive A/C
Use
When using the air conditioning
system, monitor the tempera-
ture gauge closely while driving
up hills or in heavy traffic when
outside temperatures are high.
Air conditioning system opera-
tion may cause engine over-
heating. Continue to use the
blower fan but turn the air con-
ditioning system off if the tem-
perature gauge indicates engine
overheating.
CAUTION
When opening the windows in
humid weather, air conditioning
may create water droplets
inside the vehicle. Since exces-
sive water droplets may cause
damage to electrical equipment,
air conditioning should only be
used with the windows closed.

Driving your vehicle
Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P
(Park) position.
ENGINE START/STOP button inter-
lock system (if equipped)
The ENGINE START/STOP button
will not change to the OFF position
unless the shift lever is in the P
(Park) position.Good driving practices
Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into P
(Park) when the vehicle is in motion.
Be sure the car is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
Never take the car out of gear and
coast down a hill. This may be
extremely hazardous. Always leave
the car in gear when moving.
Do not "ride" the brakes. This can
cause them to overheat and mal-
function. Instead, when you are
driving down a long hill, slow down
and shift to a lower gear. When you
do this, engine braking will help
slow the car.
Slow down before shifting to a
lower gear. Otherwise, the lower
gear may not be engaged. Always use the parking brake. Do
not depend on placing the
transaxle in P (Park) to keep the
car from moving.
Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
the vehicle to go out of control.
Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator pedal.
CAUTION
- Holding the Vehicle Using
Accelerator Pedal
Do not attempt to hold your
vehicle on a hill by applying the
accelerator pedal. This can
cause your clutch and transmis-
sion to be damaged as a result
of overheating.

Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and any
forward gear in vehicles equipped
with a dual clutch transmission. Do
not race the engine, and spin the
wheels as little as possible. If you are
still stuck after a few tries, have the
vehicle pulled out by a tow vehicle to
avoid engine overheating and possi-
ble damage to the transaxle.
The ESC system should be turned
OFF prior to rocking the vehicle.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration. If
you follow these suggestions, tire
wear will be held to a minimum.CAUTION- Vehicle rocking
Prolonged rocking may cause
engine overheating, transaxle
damage or failure, and tire dam-
age.
CAUTION- Spinning tires
Do not spin the wheels, espe-
cially at speeds more than 56
km/h (35 mph). Spinning the
wheels at high speeds when the
vehicle is stationary could
cause a tire to overheat which
could result in tire damage that
may injure bystanders.
WARNING- Sudden
Vehicle Movement
Do not attempt to rock the vehi-
cle if people or objects are near-
by. The vehicle may suddenly
move forward or backwards as it
becomes unstuck.

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING- Under/over
inflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
WARNING- Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out tires
should be replaced as soon as
possible. For further information
and tread limits, refer to "Tires
and wheels" in chapter 8.
