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 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 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
The Dual Clutch Transmissiongives the driving feel of a manual
transmission, yet provides the
ease of a fully automatic transmis-
sion. Unlike a traditional automatic
transmission, the gear shifting can
be felt (and heard) on the dual
clutch transmission
- Think of it as an automaticallyshifting manual transmission.
- Shift into Drive range and get fully automatic shifting, similar to a con-
ventional automatic transmission.
Dual clutch transmission adopts dry-type dual clutch, which is dif-
ferent from the torque converter of
an automatic transmission, and
shows better acceleration perform-
ance during driving. But, initial
launch from a stop might be little
bit slower than with an Automatic
Transmission.
The dry-type clutch transfers torque and provides a direct driving feeling
which may feel different from a con-
ventional automatic transmission
with a torque converter. This may be
more noticeable when starting from
a stop or low vehicle speed. When rapidly accelerating at low
vehicle speed, engine could rev at
higher rpm than with a comparable
Automatic Transmission.
For smooth launch uphill, press down the accelerator pedal
smoothly depending on the current
conditions.
If you release your foot from the accelerator pedal at a low vehicle
speed, you may feel strong engine
brake, which is similar to a manual
transmission.
When driving downhill, you may use Sports Mode and press the
paddle shifters to downshift to a
lower gear in order to control your
speed without using the brake
pedal excessively.
When you turn the engine on and off, you may hear clicking sounds
as the system goes through a self
test. This is a normal sound for the
Dual Clutch Transmission.
WARNING
To reduce the risk of serious
injury or death:
ALWAYS check the surround-ing areas near your vehicle for
people, especially children,
before shifting a vehicle into
D (Drive) or R (Reverse).
Before leaving the driver’s seat, always make sure the
shift lever is in the P (Park)
position, then set the parking
brake, and place the ignition
switch in the LOCK/OFF posi-
tion. Unexpected and sudden
vehicle movement can occur
if these precautions are not
followed.
Do not use engine braking (shifting from a high gear to
lower gear) rapidly on slip-
pery roads. The vehicle may
slip causing an accident.

fuel efficiency by control-
ling certain engine and

ing parameters. Fuel effi-
ciency depends on the
driver's driving habit and
road condition.

the ECO mode is select-
ed, the ECO indicator
(green) will illuminate to
show that the Active
ECO is operating.
activated, it does not
turn off even though the
engine is restarted
again. To turn off the
system, press the
DRIVE MODE button
again. When Active ECO is activated:
The acceleration may slightly be
reduced even though you depress
the accelerator fully.
The air conditioner performance may be limited
The shift pattern of the automatic transaxle may change.
The engine noise may get louder.
The above situations are normal
conditions when the Active Eco
System is activated to improve fuel
efficiency. Limitation of Active ECO opera-
tion:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
the engine torque is restricted.
When using manual mode: The system will be limited accord-
ing to the shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds:
The system will be limited, judging
that the driver wants to speed up.

Position the wrench as shown in the
drawing and tighten the wheel nuts.
Be sure the socket is seated com-
pletely over the nut. Do not stand on
the wrench handle or use an exten-
sion pipe over the wrench handle. Go
around the wheel, tightening every
nut following the numerical sequence
shown in the image until they are all
tight. Double-check each nut for
tightness. After changing wheels,
have an authorized Kia dealer tight-
en the wheel nuts to their proper
torque as soon as possible.
Wheel nut tightening torque:
9~11 kg·m (65~79 lb·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.

CAUTION
When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the related parts or make them work irregularly.
✽
✽ NOTICE
• It is permissible to add 21 kPa (3psi) 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.
