Driving your vehicle
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 (64km/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.

Multi fuse
✽ ✽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
✽ ✽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.
✽ ✽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.
Since the main fuse is designed more
intricately than other parts, have the
vehicle checked by an authorized
Kia dealer.

CAUTION
Visually inspect the battery cap
to ensure it is securely closed.If the battery cap is not securelyclosed, moisture may enter thesystem and damage the electri-cal components.

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
