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 EPS is controlled by a power
steering control unit which senses
the steering wheel torque and vehi-
cle 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. 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 posi-
tion. This happens as the system
performs the EPS system diagnos-
tics. 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 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 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.

Features of your vehicle
Air conditioning system operation tips
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system.
During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic. Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling; howev-
er, continual operation in this mode
may cause the air inside the vehi-
cle to become stale.
During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.
Automatic ventilation
The system automatically selects the
outside (fresh) air position when the
climate control system operates over
a certain period of time (5 minutes)
in low temperature with the recircu-
lated air position selected. (when
floor mode or bi-level mode)
CAUTION
When using the air condition-
ing system, monitor the tem-
perature gauge closely while
driving up hills or in heavy
traffic when outside tempera-
tures are high. Air condition-
ing system operation may
cause engine overheating.
Continue to use the blower fan
but turn the air conditioning
system off if the temperature
gauge indicates engine over-
heating.
When opening the windows in
humid weather, air condition-
ing may create water droplets
inside the vehicle. Since
excessive water droplets may
cause damage to electrical
equipment, air conditioning
should only be used with the
windows closed.
