Features of your vehicle
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system. If
dust or other pollutants accumulate in
the filter over a period of time, the air
flow from the air vents may decrease,
resulting in moisture accumulation on
the inside of the windshield even
when the outside (fresh) air position is
selected. If this happens, have the cli-
mate control air filter replaced by an
authorized Kia dealer.
✽ ✽NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner filter inspections and
changes are required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized Kia
dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a negative impact on the air con-
ditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.

WARNING - Vehicles
equipped with R-1234yf
Because the refriger-
ant is mildly inflam-
mable and at very
high pressure, the air
conditioning system
should only be serv-
iced by trained and
certified technicians.
It is important that the correct
type and amount of oil and
refrigerant is used.
Failure to heed this warning
may result in serious personal
injuries.

WARNING
The oil and refrigerant in your
vehicle's air conditioning sys-
tem is under very high pres-
sure. If proper service proce-
dures are not followed an explo-
sion may result. To reduce the
risk of serious injury or death,
the air conditioning system in

Be sure the exhaust system does
not leak.
The exhaust system should be
checked whenever the vehicle is
raised to change the oil or for any
other purpose. If you hear a change in
the sound of the exhaust or if you drive
over something that strikes the under-
neath side of the vehicle, have the
exhaust system checked as soon as
possible by an authorized Kia dealer.
WARNING- Engineexhaust
Do not inhale exhaust fumes or
leave your engine running in a
enclosed area for a prolonged
time. Exhaust fumes contain
carbon monoxide, a colorless,
odorless gas that can cause
unconsciousness and death by
asphyxiation.
WARNING- Open trunk
Do not drive with the trunk open.
Poisonous exhaust gases can
enter the passenger compart-
ment. If you must drive with the
trunk open proceed as follows:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at “Fresh”, the air flow control
at “Floor” or “Face” and the
fan at the highest speed.

Driving your vehicle
Before entering vehicle
• Be sure that all windows, outsidemirror(s), and outside lights are
clean.
Check the condition of the tires.
Check under the vehicle for any sign of leaks.
Be sure there are no obstacles behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, at the exact interval
depending on the fluid. Further
details are provided in chapter 7,
“Maintenance”.
Before starting
Close and lock all doors.
Position the seat so that all con-trols are easily reached.
Buckle your seat belt.
Adjust the inside and outside rearview mirrors.
Be sure that all lights work.
Check all gauges.
Check the operation of warning lights when the ignition switch is
turned to the ON position.
Input any phone numbers or map locations (if vehicle equipped with
a navigation system) that you may
need during your trip.
Release the parking brake and make sure the brake warning light
goes out.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.
BEFORE DRIVING
WARNING - Distracted driving
Focus on the road while driving.
The driver's primary responsi-
bility is in the safe and legal

Various driving situations, which you
may encounter in SMART mode
The driving mode automatically
changes to ECO mode after a cer-
tain period of time, when you gen-
tly depress the accelerator pedal
(Your driving is categorized to be
mild.).
The driving mode automatically changes from SMART ECO mode
to SMART COMFORT mode after
a certain period of time, when you
sharply or repetitively depress the
accelerator pedal.
The driving mode automatically changes to SMART COMFORT
mode with the same driving pat-
terns, when the vehicle starts to
drive on an upward slope of a cer-
tain angle. The driving mode auto-
matically returns to SMART ECO
mode, when the vehicle enters a
leveled road. The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
You may still sense the engine brake performance, even when you
release the accelerator pedal in
SMART SPORT mode. It is
because your vehicle remains to
be in a lower gear over a certain
period of time for next acceleration.
Thus, it is a normal driving situa-
tion, not indicating any malfunc-
tion.
The driving mode automatically changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situa-
tions, the driving mode sets to be
either in SMART ECO mode or in
SMART COMFORT mode. Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indica-
tor illuminates in those situations.)
The driver manually moves the
shift lever : It deactivates SMART
mode. The vehicle drives, as the
driver manually moves the shift
lever.
The cruise control is activated : The cruise system may deactivate
the SMART mode. When a higher
system is set by the cruise system,
it starts to control vehicle speed
and deactivates SMART mode.
(SMART mode is not deactivated
just by activing the cruise system.)
The transmission oil temperature is either extremely low or extremely
high : The SMART mode can be
active in most of the normal driving
situations. However, an extremely
high/ low transmission oil tempera-
ture may temporarily deactivate the
SMART mode, because the trans-
mission condition is out of normal
operation condition.

DRIVER’S ATTENTION
The driver must be cautious in the
below situations may not work
properly when recognition of the
lane marker is poor or limited :
  When lane and road condition is
poor

marker is covered with dust or
sand.
• It is difficult to distinguish the color of the lane marker from
road.
• There is something looks like a lane marker.

• The number of lanes increases/ decreases or the lane lines are
crossing (Driving through a toll
plaza/toll gate, merged/divided
lane).
• There are more than two lane markers.
• The lane marker is very thick or thin. (Continued)(Continued)
• The lane marker is not visible due
to snow, rain, stain, a puddle or
other factors.
• A shadow is on the lane marker because of a median strip,

for the lines such as a construc-
tion area.
• There are crosswalk signs or other symbols on the road.
• The lane suddenly disappears such as at the intersection.

vened
• The brightness of outside changes suddenly when entering/existing a
tunnel or passing under a bridge.

• There is a boundary structure in the roadway. (Continued)(Continued)
• The light of street, sun, oncoming
vehicle and so on reflects from the
water on the road.
• When light shines brightly in the reverse direction you drive.
• The distance from the vehicle ahead is very short or the vehicle
ahead drives hiding the lane line.
• You drive on a steep grade or a sharp curve.
• The vehicle vibrates heavily.
• The temperature near inside mir- ror is very high due to direct sun
light and etc.
  When front visibility is poor
• The lens or windshield is covered by strange materials.
• The sensor cannot detect the lane because of fog, heavy rain or snow.
• The windshield is fogged by humid air in the vehicle.
• Putting something on the crash pad and etc.
