How does the air bag system
operate?
Air bags are activated (able to
inflate if necessary) only when
engine start/stop button has been
changed to ON position.
The appropriate air bags inflate instantly in the event of a serious
frontal collision or side collision in
order to help protect the occupants
from serious physical injury.
There is no single speed at which the air bags will inflate.
Generally, air bags are designed to
inflate based upon the severity of a
collision and its direction. These
two factors determine whether the
sensors produce an electronic
deployment/ inflation signal.
Air bag deployment depends on a number of factors including vehicle
speed, angles of impact, and, the
density and stiffness of the vehi-
cles or objects which your vehicle
hits in the collision. The determin-
ing factors are not limited to those
mentioned above. The front air bags will completely
inflate and deflate in an instant.
It is virtually impossible for you to
see the air bags inflate during an
accident.
It is much more likely that you will
simply see the deflated air bags
hanging out of their storage com-
partments after the collision.
In addition to inflating in serious side collisions, side and/or curtain
air bags will inflate if the sensing
system detects a rollover.
When a rollover is detected, side and/or curtain air bags will remain
inflated longer to help provide pro-
tection from ejection, especially
when used in conjunction with the
seat belts. In order to help provide protection,
the air bags must inflate rapidly.
The speed of the air bag inflation is
a consequence of extremely short
time in which to inflate the air bag
between the occupant and the
vehicle structures before the occu-
pant impacts those structures. This
speed of inflation reduces the risk
of serious or life-threatening
injuries and is thus a necessary
part of the air bag design.
However, air bag inflation can also
cause injuries which can include
facial abrasions, bruises and bro-
ken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
There are even circumstances under which contact with the
steering wheel or passenger air
bag can cause fatal injuries,
especially if the occupant is
positioned excessively close to
the steering wheel or passenger
air bag.

If any of the following conditions
occur, this indicates a malfunction in
the air bag system. Have an author-
ized Kia dealer inspect the air bag
system as soon as possible.
The light does not turn on briefly
when you change engine start/stop
button to ON.
The light stays on after illuminating for approximately 6 seconds.
The light comes on while the vehi- cle is in motion.
The light blinks when engine start/stop button is ON position. The front air bag modules are locat-
ed both in the center of the steering
wheel and in the front passenger's
panel above the glove box. When the
SRSCM detects a sufficiently severe
impact to the front of the vehicle, it
will automatically deploy the front air
bags. Upon deployment, tear seams mold-
ed directly into the pad covers will
separate under pressure from the
expansion of the air bags. Further
opening of the covers then allows full
inflation of the air bags.

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 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 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 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. (Continued)

• When the charging system warninglight comes on due to the low volt-
age (When the alternator or bat-
tery) does not operate normally or
malfunctions), the steering wheel
may require increased steering
effort.Tilt and telescopic steering
Tilt and telescopic steering allows
you to adjust the steering wheel
before you drive. You can also raise it
to give your legs more room when
you exit and enter the vehicle.
The steering wheel should be posi-
tioned so that it is comfortable for
you to drive, while permitting you to
see the instrument panel warning
lights and gauges. To change the steering wheel angle,
pull down the lock-release lever (1),
adjust the steering wheel to the
desired angle (2) and height (3, if
equipped) then pull up the lock-
release lever to lock (4) the steering
wheel in place. Be sure to adjust the
steering wheel to the desired posi-
tion before driving.
✽ ✽NOTICE
After adjustment, sometimes the
lock release lever may not lock the
steering wheel. It is not a malfunc-
tion. This occurs when two gears are
not engaged correctly. In this case,
adjust the steering wheel again and
then lock the steering wheel.
WARNING- Steering

Never adjust the angle and
height of the steering wheel
