Driving your vehicle
Detecting Sensor
The rear radars are located inside
the rear bumper for detecting the
side and rear areas.
Always keep the rear bumper clean
for proper operation of the system.
ODEP059158
CAUTION
The system may not work
properly when the bumper has
been damaged, or if the rear
bumper has been replaced or
repaired.
The system may turn off due to
strong electromagnetic waves.
Always keep the sensors clean.
NEVER arbitrarily disassem-
ble the sensor component nor
apply any impact on the sen-
sor component.
Be careful not to apply unnec-
essary force on the radar sen-
sor or sensor cover. If the sen-
sor is forcibly moved out of
proper alignment, the system
may not operate correctly. In
this case, a warning message
may not be displayed.

WARNING
Drive safely even though the
vehicle is equipped with Rear
Cross-Traffic Collision
Warning system. Do not sole-
ly rely on the system but
check your surrounding when
backing the vehicle up.
The driver is responsible for
accurate brake control.
Always pay extreme caution
while driving. Rear Cross-
Traffic Collision Warning sys-
tem may not operate properly
or unnecessarily operate
depending on traffic and driv-
ing conditions.

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 is
installed.
The vehicle drives in inclement
weather such as heavy rain or
snow.
The sensor is polluted 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
liftgate, 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 road pavement (or the periph-
eral ground) abnormally contains
metallic components (i.e. possibly
due to subway construction).
There is a fixed object near the
vehicle, such as a guardrail.
While going down or up a steep
road where the height of the lane is
different.
Driving on a narrow road where
trees or grass or overgrown.
Driving in rural areas where the sen-
sor does not detect another vehicle
for an extended period of time.
Driving on a wet road.
Driving on a road where the guardrail
or wall is in double structure.
A big vehicle is near such as a bus
or truck.
When the other vehicle approaches
very close. When the other vehicle passes at a
very fast speed.
While changing lanes.
If the vehicle has started at the
same time as the vehicle next to
you and has accelerated.
When the vehicle in the next lane
moves two lanes away from you OR
when the vehicle two lanes away
moves to the next lane from you.
A motorcycle or bicycle is near.
A flat trailer is near.
If there are small objects in the
detecting area such as a shopping
cart or a baby stroller.
If there is a low height vehicle such
as a sports car.
The brake pedal is depressed.
ESC (Electronic Stability Control)
is activated.
ESC (Electronic Stability Control)
malfunctions.
The tire pressure is low or a tire is
damaged.

What to do in an emergency
18 6
You may not be able to identify a low
tire by simply looking at it. Always
use a good quality tire pressure
gauge to measure the tire's inflation
pressure. Please note that a tire that
is hot (from being driven) will have a
higher pressure measurement than a
tire that is cold (from sitting station-
ary for at least 3 hours and driven
less than 1.6 km (1 mile) during that
3 hour period).
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1.6 km (1 mile) in that 3
hour period.
Never use tire sealant if your vehicle
is equipped with a Tire Pressure
Monitoring System. The liquid
sealant can damage the tire pres-
sure sensors. The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors such as
nails or road debris.
If you feel any vehicle instability,
immediately take your foot off the
accelerator, apply the brakes grad-
ually and with light force, and slow-
ly move to a safe position off the
road.
✽ ✽
NOTICE - Protecting TPMS
Tampering with, modifying, or dis-
abling the Tire Pressure Monitoring
System (TPMS) components may
interfere with the system's ability to
warn the driver of low tire pressure
conditions and/or TPMS malfunc-
tions. Tampering with, modifying,
or disabling the Tire Pressure
Monitoring System (TPMS) compo-
nents may void the warranty for
that portion of the vehicle.
This device complies with
Industry Canada licence-exempt
RSS standard(s).
Operation is subject to the following
conditions:
1. This device may not cause inter-
ference, and
2. This device must accept any inter-
ference, including interference that
may cause undesired operation of
the device.
3. Changes or modifications not
expressly approved by the party
responsible for compliance could
void the user's authority to operate
the device.

Notes on the safe use of the
Tire Mobility Kit
Park your car at the side of the
road so that you can work with the
Tire Mobility Kit away from moving
traffic.
To be sure your vehicle will not
move, even when you're on fairly
level ground, always set your park-
ing brake.
Only use the Tire Mobility Kit for
sealing/inflation passenger car
tires. Only punctured areas located
within the tread region of the tire
can be sealed using the Tire
Mobility Kit.
Do not use on motorcycles, bicy-
cles or any other type of tires.
When the tire and wheel are dam-
aged, do not use Tire Mobility Kit
for your safety. Use of the Tire Mobility Kit may not
be effective for tire damage larger
than approximately 4 mm (0.16
in.).
Please contact the nearest Kia
dealership if the tire cannot be
made roadworthy with the Tire
Mobility Kit.
Do not use the Tire Mobility Kit if a
tire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects
such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave
the engine running. Otherwise
operating the compressor may
eventually drain the car battery.
Never leave the Tire Mobility Kit
unattended while it is being used.
Do not leave the compressor run-
ning for more than 10 min. at a time
or it may overheat.
Do not use the Tire Mobility Kit if
the ambient temperature is below -
-30°C (22°F).
WARNING
Do not use the Tire sealant after
the sealant has expired (i.e.
past the expiration date on the
sealant container). This can
increase the risk of tire failure.
CAUTION
When repairing a flat tire with
the Tire Mobility Kit (TMK),
quickly remove the sealant on
the tire pressure sensor and
wheel. When installing the
repaired tire and wheel, tighten
the wheel nut to a torque value
of 11 ~ 13 kgf·m.
WARNING - Sealant
Keep out of reach of children.
Avoid contact with eyes.
Do not swallow.
