Knowing your vehicle
✽ ✽
NOTICE• If luggage or other objects are placed
on the front passenger's seat or if the
temperature of the seat changes while
the seat is unoccupied, the "PASSEN-
GER AIR BAG OFF" indicator may
blink. These conditions do not indi-
cate a problem.
• Do not put heavy objects on the front
passenger's seat. This may cause front
passenger air bag deployment in the
event of an accident, thus increasing
your repair costs.

Kia does not endorse nor will it
support any changes to any part
or structure of the vehicle that
could affect the advanced air bag
system, including the occupant
classification system.
Specifically, the front passenger
seat, dashboard or door should
not be replaced except by an
authorized Kia dealer using origi-
nal Kia parts designed for this
vehicle and model. Any other
such replacement or modification
could adversely affect the opera-
tion of the occupant classification
system and your advanced air
bags.
For the same reason, do not
attach anything to the seat, dash-
board or door, even temporarily. If
the system is adversely affected,
it could cause severe personal
injuries or death in a collision.

(Continued)
Do not place sharp objects on the
front passenger seat. These can
damage the occupant classifica-
tion system, if they puncture the
seat cushion.
Do not install accessory seat cov-
ers on the front seats, since these
will interfere with proper sensor
operation.
WARNING
The front seat passenger’s air bag
is much larger than the steering
wheel air bag and inflates with
considerably more force. It can
seriously hurt or kill a passenger
who is not in the proper position
and wearing the safety belt prop-
erly. The front passengers
should always move their seat as
far back as practical and sit back
in their seat.
It is essential that the front pas-
sengers always wear their safety
belts when vehicle is in motion,
even when the vehicle is moving
in a parking lot or up a driveway
into garage.
If the driver brakes the vehicle
heavily in urgent situations, occu-
pants will be thrown forward. If
front passengers are not wearing
the safety belts, they will be
directly in front of the air bags
when inflation occurs. In that sit-
uation, severe injury or death is
possible.

Knowing your vehicle64 3 Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it to
“ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this "under-ride" situation
because deceleration forces that are
detected by sensors may be signifi-
cantly altered by such “under-ride” col-
lisions. Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide proper protection to
the occupants.
However, side air bags may inflate
when the vehicle is rolled over by a
side impact collision, if the vehicle is
equipped with side air bags and cur-
tain air bags. Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated to one area and
the full force of the impact is not trans-
mitted to the sensors.

Driving your vehicle
The Electronic Stability Control (ESC)
monitors information from various vehicle
sensors and then compares the driver's
commands with the actual behavior of the
vehicle. If an unstable condition occurs - a
sudden evasive movement for example -
ESC intervenes within fractions of a
second via the engine computer and
brake system and attempts to stabilize
the vehicle.
ESC operationESC ON condition

ON, ESC and ESC OFF indi-
cator lights illuminate for
approximately 3 seconds,
then ESC is turned on.

for at least half a second after
turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).

you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem.
When operating
When the ESC is in operation,
ESC indicator light blinks.

Control is operating properly,
you can feel a slight pulsation
in the vehicle. This is only the
effect of brake control and
indicates nothing unusual.

or slippery road, pressing the
accelerator pedal may not
cause the engine rpm (revo-
lutions per minute) to
increase.

Driving your vehicle38 4Operation of the rear parking
assist systemOperating condition This system will activate when backing
up with the ignition key ON.
If the vehicle is moved at speed over
5 km/h (3 mph), the system may not
activated correctly.
The sensing distance while the rear
parking assist system is in operation is
approximately 120 cm (47 in.).
When more than two objects are
sensed at the same time, the closest
one will be recognized first.Types of warning sound When an object is 120 cm to 81 cm (47
in. to 32 in.) from the rear bumper :
Buzzer beeps intermittently
When an object is 80 cm to 41 cm (31
in. to 16 in.) from the rear bumper :
Buzzer beeps more frequently
When an object is within 40 cm (15 in.)
of the rear bumper : Buzzer sounds
continuously.
Non-operational conditions of
rear parking assist systemRear parking assist system may not
operate normally when:1. Moisture is frozen to the sensor. (It will
operate normally when moisture
melts.)
2. Sensor is covered with foreign matter,
such as snow or water, or the sensor
cover is blocked. (It will operate nor-
mally when the material is removed or
the sensor is no longer blocked.)
3. Driving on uneven road surfaces
(unpaved roads, gravel, bumps, gradi-
ent).
4. Objects generating excessive noise
(vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones
are within range of the sensor.
7. Sensor is covered with snow.
8. Trailer towing
Detecting range may decrease when:1. Sensor is stained with foreign matter
such as snow or water. (Sensing range
will return to normal when removed.)
2. Outside air temperature is extremely
hot or cold.Following objects may not be recog-
nized by the sensor:1. Sharp or slim objects such as ropes,
chains or small poles.
2. Objects which tend to absorb sensor
frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 1 m
(40 in.) and narrower than 14 cm (6 in.)
in diameter.
