Electronic 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 Electronic 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 wheel 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.
• If the Electronic 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)

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.

Brake fluid
Check the brake fluid level in the
brake fluid reservoir. The level should
be between “MIN” and “MAX” marks
on the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
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.

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
