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 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)

Driving your vehicle
SMART mode selects the
proper driving mode
among ECO, COMFORT
and SPORT by judging
the driver's driving habits
(i.e. mild or dynamic)
from the brake pedal
depression or the steer-
ing wheel operation.
Press the DRIVE MODE button to activate SMART mode. When
SMART mode is activated, the
indicator illuminates on the instru-
ment cluster.
The indicator illuminates in blue, when the driver's driving is catego-
rized to be mild. It illuminates in
white, when the driver's driving is
categorized to be normal. It illumi-
nates in red, when the driver's driv-
ing is categorized to be dynamic
during abrupt braking or sharp
curving. The vehicle starts in COMFORT
mode, when the engine was turned
OFF in SMART mode.
SMART mode automatically con- trols the vehicle driving, such as
gear shifting patterns, engine
torque, riding quality (if equipped
with the electronic suspension sys-
tem), and power distribution (if
equipped with the All-Wheel Drive
(AWD) system), in accordance with
the driver's driving habits.✽ ✽ NOTICE
• When you mildly drive the vehicle
in SMART mode, the driving
mode changes to ECO mode to
improve fuel efficiency. However,
the actual fuel efficiency may dif-
fer in accordance with your driv-
ing situations (i.e. upward/down-
ward slope, vehicle
deceleration/acceleration).
• When you dynamically drive the vehicle in SMART mode by
abruptly decelerating or sharply
curving, the driving mode changes
to SPORT mode. However, it may
adversely affect fuel economy.SMART

Driving your vehicle
The Lane Keeping Assist System
detects the lane markers on the road
with a front view camera at the front
windshield, and assists the driver’s
steering to help keep the vehicle in
the lanes.When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audible warn-
ing, while applying a slight counter-
steering torque, trying to prevent the
vehicle from moving out of its lane.
✽ ✽

NOTICE
• Driver is responsible for being
aware of surroundings and steer-
ing the vehicle for safe driving
practices.
• LKA SYSTEM helps prevent the driver from moving out of the lane
unintentionally by assisting the
driver’s steering. However, the
system is just a convenience func-
tion and the steering wheel is not
always controlled. While driving,
the driver should pay attention to
the steering wheel.
• The operation of the LKA SYS- TEM can be cancelled or not work
properly according to road condi-
tion and surroundings. Always be
cautious when driving.
LANE KEEPING ASSIST (LKA) SYSTEM (IF EQUIPPED)
WARNING
Do not turn the steering wheel
suddenly when the vehicle is
being directed by the LKA sys-
tem. This can result in a sudden
loss of control and crash of the
vehicle.OUMA058032

Do not disassemble a front view
camera temporarily for tinted win-
dow or attaching any types of coat-
ings and accessories. If you disas-
semble the camera and assemble
it again, take your vehicle to an
authorized Kia dealer and have the
system checked to need a calibra-
tion.
When you replace the windshield glass, front view camera or related
parts of the steering, take your
vehicle to an authorized Kia dealer
and have the system checked to
need a calibration.
The system detects lane markers and controls the steering wheel by
a front view camera, therefore, if
the lane markers are hard to
detect, the system may not work
properly. Always be cautious when
using the system. When the lane markers are hard to
detect, please refer to “Driver’s
Attention”.
Do not remove or damage the related parts of LKA SYSTEM.
Do not place objects on the crash pad that reflects light such as mir-
rors, white paper, etc. it may cause
malfunction of LKA SYSTEM if the
sunlight is reflected.
You may not hear warning sound of LKA SYSTEM because of the
excessive audio sound.
If you continue to drive with your hands off the steering wheel, the
LKA SYSTEM will stop controlling
the steering wheel after the hands
off alarm. After then, if you drive
with your hands on the steering
wheel, the control will be activated
again.✽ ✽
NOTICE
• If the vehicle speed is high, steer-
ing torque for assistance will not
be enough to keep your vehicle
within the lane. If so, the vehicle
may move out of its lane. Obey
speed limit when using LKA SYS-
TEM.
• If you attach objects to the steer- ing wheel, the system may not
assist steering.
• If you attach objects to the steer- ing wheel, hands off alarm may
not work properly.

Driving your vehicle
Warning
If the vehicle leaves a lane, thelane marker you cross will blink on
the LCD display. If the vehicle moves out its lane
because steering torque for assis-
tance is not enough, the line indi-
cator of deviation direction will
blink.
If all the conditions to activate LKA SYSTEM are not satisfied, the sys-
tem will convert to LDW system
(Lane Departure Warning) and
warn the driver only when the driv-
er crosses the lane lines.
If the driver takes hands off the steer-
ing wheel for several seconds while
the LKA is activated, the system will
warn the driver.

Then position the wrench as shown
in the drawing and tighten the wheel
nuts. Be sure the socket is seated
completely over the nut. Do not stand
on the wrench handle or use an
extension pipe over the wrench han-
dle. Go around the wheel tightening
every nut following the numerical
sequence shown in the image until
they are all tight. Then double-check
each nut for tightness. After changing
wheels, have an authorized Kia deal-
er tighten the wheel nuts to their
proper torque as soon as possible.
Wheel nut tightening torque:
11 ~ 13 kgf·m (79 ~ 94 lbf·ft) If you have a tire gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. Always reinstall
the valve cap after checking or
adjusting the tire pressure. If the cap
is not replaced, dust and dirt may get
into the tire valve and air may leak
from the tire. If you lose a valve cap,
buy another and install it as soon as
possible.
After you have changed the wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations.
Note that most lug nuts do not have
metric threads. Be sure to use
extreme care in checking for thread
style before installing aftermarket lug
nuts or wheels. If in doubt, consult an
authorized Kia dealer.
CAUTION- Reusing lug
nuts
Make certain during wheelremoval that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the samechamfer configuration are used.Your vehicle has metric threadson the wheel studs and nuts.Installation of a non-metricthread nut on a metric stud willnot secure the wheel to the hubproperly and will damage thestud so that it must be replaced.

✽ ✽ NOTICE
• It is permissible to add 21 kPa (3 psi) to the standard tire pressure specification if colder temperatures are expect-
ed soon.
Tires typically loose 1psi for every -11°C (12°F) temperature drop. If extreme temperature variations are expect-
ed, re-check your tire pressure as necessary to keep them properly inflated.
• We recommend that when replacing tires, use the same originally supplied with the vehicles. If not, that aff\
ects driving performance.
• When driving in high altitude grades, it is natural for the atmospheric pressure to decrease. Therefore, please check the tire pressure and add more air when necessary.
Additionally required tire air pressure per km above sea level: 10 kPa (1.5psi/km)
