Introduction
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. “E85” is not compati-
ble with your vehicle. Use of “E85”
may result in poor engine perform-
ance and damage to your vehicle's
engine and fuel system. Kia recom-
mends that customers do not use
fuel with an ethanol content exceed-
ing 15 percent.
✽ ✽ 
 
NOTICE
Your New Vehicle Limited Warranty
does not cover damage to the fuel sys-
tem or any performance problems
caused by the use of “E85” fuel.
✽ ✽  
 
NOTICE
Never use any fuel containing
methanol. Discontinue use of any
methanol containing product which
may inhibit proper drivability.
Other fuels
Using fuels that contain Silicone (Si),
MMT (Manganese, Mn), Ferrocene
(Fe), and Other metalic additives,
may cause vehicle and engine dam-
age or cause misfiring, poor acceler-
ation, engine stalling, catalyst melt-
ing, clogging, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
✽ ✽  
 
NOTICE
Damage to the fuel system or per-
formance problem caused by the use
of these fuels may not be covered by
your New Vehicle Limited
Warranty. 
Gasoline containing MMT
Some gasoline contains harmful man-
ganese-based fuel additives Such as
MMT(Methylcyclopentadienyl
Manganese Tricarbonyl). Kia does not
recommend the use of gasoline con-
taining MMT. This type of fuel can
reduce vehicle performance and affect
your emission control system. The
Malfunction Indicator Lamp on the
cluster may come on.
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damage
components of the fuel system,
engine control system and emission
control system.

Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance perform-
ance of the Emission Control System.
For more information on TOP TIER
Detergent Gasoline, please go to the
website (www.toptiergas.com)
For customers who do not use TOP
TIER Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that can be purchased sepa-
rately may be added to the gasoline.
If TOP TIER Detergent Gasoline is
not available, one bottle of additive
should be added to the fuel tank at
every 7,500 miles (12,000 km) or
every engine oil change is recom-
mended. Additives are available from
your authorized Kia dealer along with
information on how to use them. Do
not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
 Observe all regulations regardingregistration and insurance.
 Determine that acceptable fuel is available.

Storing positions into memory
using the buttons on the door
Storing driver’s seat positions
1. Shift the shift lever into P while the engine start/stop button is ON.
2. Adjust the driver’s seat and out- side rearview mirror comfortable
for the driver.
3. Press SET button on the control panel. The system will beep once.
4. Press one of the memory buttons (1 or 2) within 5 seconds after
pressing the SET button. The sys-
tem will beep twice when memory
has been successfully stored.
When recalling an adjustment mem-
ory button while sitting in the vehicle,
you can be surprised by the setting
chosen if the memory has been
adjusted by someone else. If that
occurs, immediately push the seat
position control knob in the direction
of the desired position to stop further
undesired movement. Recalling positions from memory
1. Shift the shift lever into P while the
engine start/stop button is ON.
2. To recall the position in the memo- ry, press the desired memory but-
ton (1 or 2). The system will beep
once, then the driver’s seat will
automatically adjust to the stored
position.
Adjusting the control switch for the
driver’s seat while the system is
recalling the stored position will
cause the movement to stop and
move in the direction that the control
switch is moved.

The system will move the driver's
seat automatically as follows:
 With smart key system - It will move the driver’s seat rear-ward when the engine start/stop
button is changed to the OFF

the upright position, remember to
return the rear shoulder belts to their
proper position.
CAUTION - Damaging
rear seat belt buckles
When you fold the rear seat- back, insert the buckle betweenthe rear seatback and cushion.Doing so can prevent the bucklefrom being damaged by the rearseatback.
WARNING - Cargo loading
Make sure the engine is off, the
automatic transaxle is in P (Park)
and the parking brake is secure-
ly applied whenever loading or
unloading cargo. Failure to take
these steps may allow the vehi-
cle to move if the shift lever is
inadvertently moved to another
position.
WARNING- Cargo
Cargo should always be
secured to prevent it from being
thrown about the vehicle in a
collision and causing injury to
the vehicle occupants. Do not
place objects in the rear seats,
since they cannot be properly
secured and may hit the front
seat occupants in a collision.WARNING - Rear
Seatback
To ensure maximum protection
in the event of an accident or
sudden stop, when returning the
rear seat to the upright position:
 Be careful not to damage the seat belt webbing or buckle.
 Do not allow the seat belt webbing or buckle to become
pinched or caught in the rear
seat.
 Ensure the seatback is com- pletely locked into its upright
position by pushing on the
top of the seatback.
Failure to adhere to any of
these instructions could

 No modifications or additions
should be made by the user which
would either prevent the seat belt
adjusting devices from operating to
remove slack, or prevent the seat
belt assembly from being adjusted
to remove slack.
 When you fasten the seat belt, be careful not to latch the seat belt in
buckles of other seat. It's very dan-
gerous and you may not be pro-
tected by the seat belt properly.
 Do not unfasten the seat belt and do not fasten and unfasten the seat
belt repeatedly while driving. This
could result in loss of control, and
an accident causing death, serious
injury, or property damage.
 When fastening the seat belt, make sure that the seat belt does
not pass over objects that are hard
or can break easily. Driver's seat belt warning
As a reminder to the driver, the seat
belt warning light will illuminate and
warning chime will sound for approx-
imately 6 seconds each time engine
start/stop button is ON if the seat belt
is unfastened.
WARNING- Seat belt
buckle
Do not allow foreign material
(gum, crumbs, coins, etc.) to
obstruct the seat belt buckle.
This may prevent the seat belt
from fastening securely.
