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)

Driving your vehicle
The Lane Keeping Assist system is
designed to detect 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
• LKA helps prevent the driver
from moving out of the lane unin-
tentionally by assisting the dri-
ver’s steering. However, the sys-
tem is just a convenience function
and the steering wheel is not
always controlled. While driving,
the driver should pay attention to
the steering wheel.
• The operation of the LKA can be cancelled or not work properly
according to road condition and
surroundings. Always be cautious
when driving.
• Do not disassemble a front view camera temporarily for tinted
window or attaching any types of
coatings and accessories.
If you disassemble the camera and
assemble it again, take your vehi-
cle to an authorized Kia dealer
and have the system checked to
need a calibration. (Continued)
LANE KEEPING ASSIST (LKA) SYSTEM (IF EQUIPPED)
WARNING
Driver is responsible for being
aware of surroundings and
steering the vehicle for safe
driving practices.
Do not steer the steering wheel suddenly when the
steering wheel is being assist-
ed by the system.
WARNING
The Lane Keeping Assist System
is a supplemental system and is
not a substitute for safe driving
practices. It is the responsibility
of the driver to always pay atten-
tion and drive safely.

(Continued)
• When you replace the windshield
glass, front view camera or related
parts of the steering, take your
vehicle to an authorized Kia deal-
er 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.
• Do not place objects on the crash pad that reflects light such as mir-
rors, white paper, etc. it may cause
malfunction of LKA if the sunlight
is reflected. (Continued)(Continued)
• You may not hear warning sound
of LKA because of the excessive
audio sound.
• If you continue to drive with your hands off the steering wheel, the
LKA 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.
• 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.
• 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.LKA operation
To activate/deactivate the LKA:
With the ignition switch in the ON
position, press the LKA button locat-
ed on the instrument panel on the
lower left hand side of the driver.
The indicator in the cluster display
will initially illuminate white.
When the indicator(white) activated
in the previous ignition cycle, the
system turns on without any control.
If you press the LKA button again,
the indicator on the cluster display
will go off.

If the speed of the vehicle is over 40
mph (64 km/h) and the system
detects lane markers, the color
changes from gray to white
When the conditions below are met,
LKA will be enable to assist steering.
Vehicle speed is above 40 mph (64
km/h).
Both lane markers are detected by LKA.
The vehicle is between the lane markers.
If LKA can assist steering, a green
steering wheel indicator will illumi-
nate.
Warning
If the vehicle leaves a lane, the lane
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 indica-
tor will blink. If all the conditions to activate LKA
is not satisfied, the system will con-
vert to LDW and warn the driver
only when the driver crosses the
lane markers. In this scenario, the
LDW system does not provide any
steering inputs into the vehicle for
you. Accordingly, you must take the
necessary steps to maintain con-
trol of the vehicle and keep it with-
in the lanes.

What to do in an emergency
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:
79~94 lbf·ft (11~13 kgf·m)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.

Introduction
With the Tire Mobility Kit (TMK) you
stay mobile even after experiencing a
tire puncture.
The system compressor and sealing
compound effectively seal most
punctures in a passenger car tire
caused by nails or similar objects and
reinflates the tire.
After you ensure that the tire is prop-
erly sealed, you can drive cautiously
on the tire at a max. speed of 50 mph
(80 km/h) in order to reach a vehicle
or tire dealer to have the tire replaced.
WARNING- Temporary fix
Have your tire repaired as soon
as possible. The tire may lose
air pres-sure at any time after
inflating with the Tire Mobility
Kit.WARNING- Tire wall
Do not use the Tire Mobility Kit
to repair large punctures or
damage to the tire sidewalls. In
these situations, the tire cannot
be sealed completely and airwill
leak from the tire. This can
result in tire failure.
CAUTION
When repairing a flat tire with the Tire Mobility Kit (TMK),quickly remove the sealant onthe tire pressure sensor andwheel. When installing therepaired tire and wheel, tightenthe wheel nut to a torque valueof 24~28 ft.lb.

Maintenance
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake discs, pads, calipers
and rotors
Check the pads and discs for exces-
sive wear and calipers for fluid leak-
age.
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and damage.When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important in dusty or sandy
areas and when the vehicle is used
on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.

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 3psi to the standard tire pressure specification if colder temperatures are expected soon.
Tires typically loose 1psi for every 12°F temperature drop. If extreme temperature variations are expected, 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: 1.5psi/km
