fuel type KIA Optima 2012 3.G Owner's Manual

Introduction
41
Use of MTBE
Kia recommends avoiding fuels contain-
ing MTBE (Methyl Tertiary Butyl Ether)
over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
Fuel Additives
Kia recommends that you use good qual-
ity gasolines treated with detergent addi-
tives such as TOP TIER Detergent
Gasoline, which help prevent deposit for-
mation in the engine. These gasolines
will help the engine run cleaner and
enhance performance 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, additives that you can buy
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is not
available, one bottle of additive added to
the fuel tank at every 12,000 km or every
engine oil change is recommended.
Additives are available from your author-
ized Kia dealer along with information on
how to use them. Do not mix other addi-
tives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg- istration and insurance.
Determine that acceptable fuel is avail- able. No special break-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
Do not race the engine.
While driving, keep your engine speed
(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or slow.
Varying engine speed is needed to
properly break-in the engine.
Avoid hard stops, except in emergen- cies, to allow the brakes to seat prop-
erly.
Don't let the engine idle longer than 3 minutes at one time.
Don't tow a trailer during the first 2,000 km (1,200 miles) of operation.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob- lems that are caused by the use offuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)
VEHICLE BREAK-IN PROCESS

429
Features of your vehicle
(Continued)
If a fire breaks out during refuel-ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment. Follow any safety instruc-
tions they provide.(Continued)
Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
Do not use cellular phones while refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
When refueling, always shut the engine off. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler cap and filler door are
securely closed, before starting
the engine.
DO NOT use matches or a lighter and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
(Continued)CAUTION
Make sure to refuel your vehicleaccording to the "Fuel require-ments" suggested in section 1.
If the fuel filler cap requires replacement, use only a genuineKia cap or the equivalent speci-fied for your vehicle. An incorrect fuel filler cap can result in a seri-ous malfunction of the fuel sys- tem or emission control system.
Do not spill fuel on the exterior surfaces of the vehicle. Any typeof fuel spilled on painted surfacesmay damage the paint.
After refueling, make sure the fuel cap is installed securely to pre-vent fuel spillage in the event ofan accident.

The tachometer pointer may move slight-
ly when the ignition switch is in ACC or
ON position with the engine OFF. This
movement is normal and will not affect
the accuracy of the tachometer once the
engine is running.
Fuel gauge
The fuel gauge indicates the approxi-
mate amount of fuel remaining in the fuel
tank. The fuel tank capacity is given in
section 8. The fuel gauge is supplement-
ed by a low fuel warning light, which will
illuminate when the fuel tank is nearly
empty.
On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
CAUTION
Do not operate the engine within
the tachometer's RED ZONE. This may cause severe engine damage.
OTF040058
WARNING- Fuel gauge
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addition-
al fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
E level.
CAUTION
Avoid driving with extremely lowfuel level. Running out of fuel couldcause the engine to misfire, damag- ing the catalytic converter.

Engine temperature gauge
This gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
Trip computer
The trip computer is a microcomputer-
controlled driver information system that
displays information related to driving on
the display when the ignition switch is in
the ON position. All stored driving infor-
mation (except odometer) is reset if the
battery is disconnected.■ ■

Odometer (km or mi.)
The odometer indicates the total dis-
tance the vehicle has been driven.
You will also find the odometer useful to
determine when periodic maintenance
should be performed.
The odometer is always displayed until
the display is turned off. Tripmeter (km or mi.)
TRIP A : Tripmeter A
TRIP B : Tripmeter B
This mode indicates the distance of indi-
vidual trips selected since the last trip-
meter reset.
The meter's working range is from 0.0 to
9999.9 km (0.0 to 9999.9 miles).
Pressing the RESET button for more
than 1 second, when the tripmeter (TRIP
A or TRIP B) is being displayed, clears
the tripmeter to zero (0.0).

Features of your vehicle
Distance to empty (km or mi.)
This mode indicates the estimated dis-
tance to empty based on the current fuel
in the fuel tank and the amount of fuel
delivered to the engine. When the
remaining distance is below 50 km (30
miles), “---” will be displayed and the dis-
tance to empty indicator will blink.
The meter’s working range is from 50 to
990 km (30 to 990 miles).Average fuel consumption (if equipped)
(l/100 km or MPG)
This mode calculates the average fuel
consumption from the total fuel used and
the distance since the last average con-
sumption reset. The total fuel used is cal-
culated from the fuel consumption input.
For an accurate calculation, drive more
than 50 m (0.03 miles).
Pressing the RESET
button for more than
1 second, when the average fuel con-
sumption is being displayed, clears the
average fuel consumption to zero (---).
If the vehicle speed exceeds 1 km/h after
refueled more than 6 l , the average fuel
consumption will be cleared to zero (---). Instant fuel consumption
(l/100 km or MPG)
This mode calculates the instant fuel
consumption every 2 seconds from the
driving distance and quantity of fuel
injection.

Average speed (km/h or MPH)
This mode calculates the average speed
of the vehicle since the last average
speed reset.
Even if the vehicle is not in motion, the
average speed keeps going while the
engine is running.
Pressing the RESET button for more
than 1 second, when the average speed
is being displayed, clears the average
speed to zero (---). Elapsed time
This mode indicates the total time trav-
eled since the last driving time reset.
Even if the vehicle is not in motion, the
driving time keeps going while the engine
is running.
The meter’s working range is from
0:00~99:59.
Pressing the RESET button for more
than 1 second, when the driving time is
being displayed, clears the driving time to
zero (0:00).
✽ ✽
NOTICE
• If the vehicle is not on level ground or
the battery power has been interrupt-
ed, the “Distance to empty” function
may not operate correctly.
The trip computer may not register
additional fuel if less than 6 liters (1.6
gallons) of fuel are added to the vehi-
cle.
• The fuel consumption (if equipped) and distance to empty values may
vary significantly based on driving
conditions, driving habits, and condi-
tion of the vehicle.
• The distance to empty value is an esti- mate of the available driving distance.
This value may differ from the actual
driving distance available.
