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.

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.

The ABS warning light will stay on for
approximately 3 seconds after the
engine start/stop button is ON.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized Kia dealer as soon as
possible. When you drive on a road having
poor traction, such as an icy road,
and have operated your brakes
continuously, the ABS will be active
continuously and the ABS warning
light may illuminate. Pull your vehi-
cle over to a safe place and stop
the engine.
Restart the engine. If the ABS warning light goes off, then your
ABS system is normal. Otherwise,
you may have a problem with the
ABS. Contact an authorized Kia
dealer as soon as possible.
✽ ✽ NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on at
the same time. This happens because
of low battery voltage. It does not
mean your ABS has malfunctioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic stability control
(ESC)
The Electronic Stability control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle.

ESC OFF usage
When driving
ESC should be turned on for daily
driving whenever possible.
To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.
✽ ✽ NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated). If the ESC is left on,
it may prevent the vehicle speed
from increasing, and result in false
diagnosis.
• Turning the ESC off does not affect ABS or brake system opera-
tion.WARNING- Electronic sta-
bility control
Drive carefully even though your
vehicle has Electronic Stability
Control. It can only assist you in
maintaining control under cer-
tain circumstances.
WARNING- Operating ESC
Never press the ESC OFF but-
ton while ESC is operating (ESC
indicator light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip
out of control.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
Drive cautiously and allow extra
distance for braking.
Avoid sudden braking or steering.
When braking with non-ABS brakes pump the brake pedal with
a light up-and-down motion until
the vehicle is stopped.
Do not pump the brake pedal on a
vehicle equipped with ABS. If stalled in snow, mud, or sand,
use the second gear. Accelerate
slowly to avoid spinning the drive
wheels.
Use sand, rock salt, or other non- slip material under the drive
wheels to provide traction when
stalled in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and any
forward gear in vehicles equipped
with an Automatic Transmission. Do
not race the engine, and spin the
wheels as little as possible. If you are
still stuck after a few tries, have the
vehicle pulled out by a tow vehicle to
avoid engine overheating and possi-
ble damage to the transmission.
SPECIAL DRIVING CONDITIONS
WARNING- Downshifting
Do not downshift with an auto-
matic transmission while driv-
ing on slippery surfaces. The
sudden change in tire speed
could cause the tires to skid
and result in an accident.
WARNING- Sudden
Vehicle Movement
Do not attempt to rock the vehi-
cle if people or objects are near-
by. The vehicle may suddenly
move forward or backwards as it
becomes unstuck.

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.
