Non-operational conditions of
the parking distance warning-
reverse system
The parking distance warning-
reverse system may not operate
properly when:
1. Moisture is frozen to the sensor. (It will operate normally once the
moisture clears.)
2. The sensor is covered with foreign matter, such as snow or water, or
the sensor cover is blocked. (It will
operate normally when the materi-
al is removed or the sensor is no
longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps,
gradient).
4. Objects generating excessive noise (vehicle horns, loud motor-
cycle 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. The sensor is covered with snow.
8. Trailer towing. The detecting range may decrease
when:
1. The sensor is covered with foreign
matter such as snow or water.
(The sensing range will return to
normal when removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be
recognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sensor frequency such as clothes,
sound absorbent material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower
than 14 cm (6 in.) in diameter.

Parking distance warning-
reverse system precautions
The parking distance warning-
reverse system may not sound
consistently depending on the
speed and shapes of the objects
detected.
The parking distance warning- reverse system may malfunction if
the vehicle bumper height or sen-
sor installation has been modified
or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor
performance.
The sensor may not recognize objects less than 40 cm (15 in.)
from the sensor, or it may sense an
incorrect distance. Use caution.
When the sensor is frozen or cov- ered with snow, dirt, or water, the
sensor may be inoperative until the
material is removed using a soft
cloth.
To prevent damage, do not push, scratch or strike the sensor.
✽ ✽ NOTICE
This system can only sense objects
within the range and location of the
sensors. It cannot detect objects in
other areas where sensors are not
installed. Also, small or slim objects,
such as poles or objects located
between sensors may not be detected
by the sensors.
Always visually check behind the
vehicle when backing up.
Be sure to inform any drivers of the
vehicle that may be unfamiliar with
the system regarding the system’s
capabilities and limitations.
Self-diagnosis
If you don’t hear an audible warning
sound or if the buzzer sounds inter-
mittently when shifting the gear to the
R (Reverse) position, this may indi-
cate a malfunction in the parking dis-
tance warning-reverse system. If this
occurs, have your vehicle checked by
an authorized Kia dealer as soon as
possible.
✽ ✽NOTICE
Your new vehicle warranty does not
cover any accidents or damage to
the vehicle or injuries to its occu-
pants due to a parking distance
warning-reverse system malfunc-
tion. Always drive safely and cau-
tiously.

Driving your vehicle
Anti-lock brake system (ABS)
ABS (or ESC) will not prevent acci-
dents due to improper or dangerous
driving maneuvers. Even though
vehicle control is improved during
emergency braking, always maintain
a safe distance between you and
objects ahead. Vehicle speeds
should always be reduced during
extreme road conditions. The vehicle
should be driven at reduced speeds
in the following circumstances:
When driving on rough, gravel orsnow-covered roads
When driving on roads where the road surface is pitted or has differ-
ent surface heights.
Driving in these conditions increases
the stopping distance for your vehicle. The ABS continuously senses the
speed of the wheels. If the wheels
are going to lock, the ABS system
repeatedly modulates the hydraulic
brake pressure to the wheels.
When you apply your brakes under
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible to allow the ABS to
control the force being delivered to the
brakes.
✽ ✽
NOTICE
A click sound may be heard in the
engine compartment when the vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the anti-lock brake
system is functioning properly.
Even with the anti-lock brake sys-
tem, your vehicle still requires suf-
ficient stopping distance. Always
maintain a safe distance from the
vehicle in front of you.
Always slow down when cornering. The anti-lock brake system cannot
prevent accidents resulting from
excessive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake
system may result in a longer stop-
ping distance than for vehicles
equipped with a conventional
brake system.

Driving your vehicle
Check Blind-Spot Collision Warning
(BCW) system
If there is a problem with the BCW
system, a warning message will
appear and the light on the switch
will turn off. The system will turn off
automatically. BCW and RCCW will
operate also if the BCW system
turns off due to malfunction. We rec-
ommend that the system be checked
by an authorized Kia dealer.
Limitations of the system
The driver must be cautious in the
below situations, because the sys-
tem may not detect other vehicles or
objects in certain circumstances.
When a trailer or carrier isinstalled.
The vehicle drives in inclement weather such as heavy rain or
snow.
The sensor is covered with rain, snow, mud, etc.
The rear bumper where the sensor is located is covered with a foreign
object such as a bumper sticker, a
bumper guard, a bike rack, etc.
The rear bumper is damaged, or the sensor is out of the original
default position.
The vehicle height gets lower or higher due to heavy loading in a
trunk, abnormal tire pressure, etc.
When the temperature of the rear bumper is high. When the sensors are blocked by
other vehicles, walls or parking-lot
pillars.
The vehicle drives on a curved road.
The vehicle drives through a toll- gate.
The road pavement (or the periph- eral ground) abnormally contains
metallic components (i.e. possibly
due to subway construction).

The BCW system may not operate
properly when driving on a slope. In
certain instances the system may not
detect the vehicle in the next lane.
Also, in certain instances the system
may wrongly recognize the ground or
structures.
Always pay attention to road and
driving conditions while driving. Driving where the heights of the
lanes are different
The BCW system may not operate
properly when driving where the
heights of the lanes are different.
In certain instances, the system may
not detect the vehicle on a road with
different lane heights (underpass
joining section, grade separated
intersections, etc.).
Always pay attention to road and
driving conditions, while driving.[A] : noise barrier, [B] : guardrail
Driving where there is a structure beside the road

Maintenance
Tire replacement
If the tire is worn evenly, a tread wear
Indicator (A) will appear as a solid
band across the tread. This shows
there is less than 1.6 mm (1/16 inch)
of tread left on the tire. Replace the
tire when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.The ABS works by comparing the
speed of the wheels. The tire size
affects wheel speed. When replacing
tires, all 4 tires must use the same
size originally supplied with the vehi-
cle. Using tires of a different size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregularly.
✽ ✽

NOTICE
We recommend that when replacing
tires, use the same which were origi-
nally supplied with the vehicle. If
not, driving performance could be
altered.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
A wheel that is not the correct size
may adversely affect wheel and
bearing life, braking and stopping
abilities, handling characteristics,
ground clearance, body-to-tire clear-
ance, snow chain clearance,
speedometer and odometer calibra-
tion, headlight aim and bumper
height.
