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 improved 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 position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics are complet-
ed, the steering system 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. (Continued)

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.
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 turn the steering wheel suddenly when the steering
wheel is being assisted 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.
OJFHP058305L
WARNING
The operation of the LKA canbe cancelled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
Do not disassemble the front view camera temporarily for
tinting window or attaching
any types of coatings and
accessories.
If you disassemble the camera
and assemble it again, take
your vehicle to an authorized
Kia dealer and have the system
checked to need a calibration.
When you replace the wind- shield glass, front view camera
or parts of the steering, take
your vehicle to an authorized
Kia dealer and have the system
checked to need a calibration.

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.
If the indicated (white) was activated
in the previous ignition cycle, the
system will remain activated.
If you press the LKA button again,
the indicator on the cluster display
will go off.
OJFHP058308
(Continued)
The system is designed todetect lane markers using a
front view camera. If the lane
markers are hard to detect,
then the system may be limit-
ed. 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 dashboard that reflects light
such as mirrors, white paper,
etc. This may prevent the LKA
system from functioning
properly.
You may not hear warning sound of LKA if the audio vol-
ume is high.
(Continued)(Continued)
If you to drive with your handsoff the steering wheel, the
LKA will stop controlling the
steering wheel after the hands
off alarm. If you drive with
your hands on the steering
wheel again the control will be
activated again.
If the vehicle speed is high, steering 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 steering wheel, the system
may not assist steering.
If you attach objects to the steering wheel, hands off
alarm may not work properly.

Driving your vehicle
If the speed of the vehicle is over 60
km/h (37 mph) 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 64 km/h(40 mph).
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 are not satisfied, the system will
convert to the Lane Departure
Warning (LDW) system and warn
the driver only when the driver
crosses the lane markers. If the driver takes hands off the steer-
ing wheel for several seconds while
the LKA is activated, the system will
warn the driver.

IF YOU HAVE A FLAT TIRE (WITH TIRE MOBILITY KIT)
Please read the instructions before
using the Tire Mobility Kit.
(1) Compressor
(2) Sealant bottle
The Tire Mobility Kit is a temporary
fix to the tire and the tire should be
inspected by an authorized Kia deal-
er as soon as possible.
✽ ✽
NOTICE
When repairing a flat tire with the
Tire Mobility Kit (TMK), quickly
remove the sealant on the tire pres-
sure sensor and wheel. When
installing the repaired tire and
wheel, tighten the wheel nut to a
torque value of 11 ~ 13kgf·m.
OJFH068043WARNING- 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 air
will leak from the tire. This can
result in tire failure.
CAUTION - One sealant for one tire
When two or more tires are flat,do not use the Tire Mobility Kitbecause the canister of sealantonly contains enough sealantfor one flat tire.
WARNING- Speed with temporary fix
Do not exceed a speed of 80
km/h (50 mph) when driving
with a tire sealed with the Tire
Mobility Kit. While driving, if you
experience any unusual vibra-
tion, ride disturbance or noise,
reduce your speed and drive
with caution until you can safe-
ly pull off the side of the road.
WARNING
- Temporary fix
Have your tire repaired as soon
as possible. The tire may lose air
pressure at any time after inflat-
ing with the Tire Mobility Kit.

Maintenance
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 dam-
age.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.

NOTICE
Do not disassemble nor assemble the
multi fuse when it is secured with
nuts and bolts. Incorrect or partial
assembly torque may cause a fire.
Have the vehicle checked by an
authorized Kia dealer.
Main fuse
If the main fuse is blown, it must be
removed as follows:
1. Turn off the engine.
2. Disconnect the negative battery
cable.
3. Remove the nuts shown in the pic- ture above.
4. Replace the fuse with a new one of the same rating.
5. Reverse these steps to reinstall the main fuse.
✽ ✽NOTICE
The electronic system may not func-
tion correctly even when the engine
compartment and internal fuse
box’s individual fuses are not dis-
connected. In such case the cause of
the problem may be disconnection
of the main fuse (BFT type), which is
located inside the positive battery
terminal (+) cap.

Specification & Consumer information
TIRES AND WHEELS
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 (3 psi) to the standard tire pressure specification if colder temperatures are expect-
ed soon.
Tires typically lose 7 kPa (1 psi) for every -11°C (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: 10.5 kPa (1.5psi/km)
