Why didn’t my air bag go off in
a collision? (Inflation and non-
inflation conditions of the air
bag)
There are many types of accidents
in which the air bag would not be
expected to provide additional
protection.
These include rear impacts, sec-
ond or third collisions in multiple
impact accidents, as well as low
speed impacts.

Safety features of your vehicle
Problems may arise if the sensor
installation angles are changed due
to the deformation of the front
bumper, body or B pillar where side
collision sensors are installed. Have
the vehicle checked and repaired by
an authorized Kia dealer.
Installing aftermarket bumper guards
or replacing a bumper with non-gen-
uine parts may adversely affect your
vehicle’s collision and air bag deploy-
ment performance.Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the intensity, speed or angles of
impact of the front collision.
WARNING - Air bag sensors
Do not hit or allow any objects to impact the locations where
air bag or sensors are installed.
This may cause unexpected
air bag deployment, which
could result in serious per-
sonal injury or death.
If the installation location or angle of the sensors is altered
in any way, the air bags may
deploy when they should not
or they may not deploy when
they should.
Therefore, do not try to per-
form maintenance on or
around the air bag sensors.
Have the vehicle checked and
repaired by an authorized Kia
dealer.

❈ The actual air bags in the vehicle may differ
from the illustration.
Side air bags
Side air bags (side and/or curtain air
bags) are designed to inflate when
an impact is detected by side colli-
sion sensors depending on the
strength, speed or angles of impact
resulting from a side impact collision. Although the front air bags (driver’s
and front passenger’s air bags) are
designed to inflate in frontal colli-
sions, they also may inflate in other
types of collisions if the front impact
sensors detect a sufficient frontal
force in another type of impact. Side
and curtain air bags are designed to
inflate in certain side impact colli-
sions. They may inflate in other type
of collisions where a side force is
detected by the sensors.
If the vehicle chassis is impacted by
bumps or objects on unimproved
roads or sidewalks, air bags may
deploy. Drive carefully on unim-
proved roads or on surfaces not
designed for vehicle traffic to prevent
unintended air bag deployment.
Air bag non-inflation conditions
In certain low-speed collisions the
air bags may not deploy. The air
bags are designed not to deploy in
such cases because they may not
provide benefits beyond the pro-
tection of the seat belts in such col-
lisions.

Features of your vehicle
The smart key will not work if any of
following occurs:
The ignition key is in the ignitionswitch.
You exceed the operating distance limit (about 90 feet [30 m]).
The battery in the smart key is weak.
Other vehicles or objects may be blocking the signal.
The weather is extremely cold.
The smart key is close to a radio transmitter such as a radio station or
an airport which can interfere with
normal operation of the transmitter.
When the smart key does not work
properly, open and close the door
with the ignition key. If you have a
problem with the smart key, contact
an authorized Kia dealer. If the smart key is in close proximity
to your cell phone or smart phone,
the signal from the smart key could
be blocked by normal operation of
your cell phone or smart phone.
This is especially important when
the phone is active such as making
call, receiving calls, text messaging,
and/or sending/receiving emails.
Avoid placing the smart key and
your cell phone or smart phone in
the same pants or jacket pocket and
maintain adequate distance
between the two devices. This device complies with Part 15
of the FCC rules.
Operation is subject to the following
two conditions:
1. This device may not cause harm-
ful interference, and
2. This device must accept any inter- ference received, including inter-
ference that may cause undesired
operation.

ECO GUIDE gauge
This is a gauge to let drivers know
efficient the current driving condi-
tions are. The fuel efficiency is high
in the green zone but is low in the red
zone.
- Green zone : Good driving condi-tion
- White zone : Average driving con- dition
- Red zone : Poor driving condition
Odometer
The odometer indicates the total dis-
tance the vehicle has been driven.
You will also find the odometer useful
to determine when periodic mainte-
nance should be performed.
Outside temperature display
This display indicates the current
outside air temperatures by 1°F

‘Check brake' is displayed when the
brake function is not well or the
regenerative brake system is not
operated with brake system malfunc-
tion. Refer to the "Brake system
warning light" in this chapter.

Non-operational conditions of
Back-Up Warning System
The Back-Up Warning System may
not operate properly when:
1. Moisture is frozen to the sensor. (It
will operate normally when the
moisture has been cleared.)
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 stained 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,
spongy material or snow.
3. Undetectable objects smaller than 40 in. (1 m) in height and narrower
than 6 in. (14 cm) in diameter.
Back-Up Warning System pre-
cautions
The Back-Up Warning System maynot sound sequentially depending
on the speed and shapes of the
objects detected.
The Back-Up Warning 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 11 in. (30 cm)
from the sensor, or it may sense an
incorrect distance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains
are removed using a soft cloth.
Do not push, scratch or strike the sensor. Sensor damage could occur.
