• 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

Non-operational conditions of
rear parking assist system
The rear parking assist 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 40 in. (1 m) in height and narrower
than 6 in. (14 cm) in diameter.

Rear parking assist system
precautions
The rear parking assist system
may not sound consistently
depending on the speed and
shapes of the objects detected.
The rear parking assist system may malfunction if the vehicle bumper
height or sensor 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 15 in. (40 cm)
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 systems
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 rear parking
assist system. If this occurs, have
your vehicle checked by an author-
ized 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 rear parking assist
system malfunction. Always drive
safely and cautiously.

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 or
snow-covered roads
When driving with tire chains installed
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 or as hard as the sit-
uation allows 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.

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 1/16 inch (1.6 mm)
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.
