Features of your vehicle
Engine coolant temperature gauge
This gauge shows the temperature
of the engine coolant when the igni-
tion switch is ON.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the engine over-
heats" in chapter 6.
If the gauge pointer moves beyond
the normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Fuel gauge
The fuel gauge indicates the approx-
imate amount of fuel remaining in the
fuel tank. The fuel tank capacity is
given in chapter 8. The fuel gauge is
supplemented 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.
WARNING - Fuel gauge
Stop and obtain additional fuel
as soon as possible after the
warning light comes on or when
the gauge indicator comes
close to the E level. Running out
of fuel can expose vehicle occu-
pants to danger.
CAUTION - Low fuel
Avoid driving with extremelylow fuel level. Running out offuel could cause the engine tomisfire, damaging the catalyticconverter.OTF044057

In this case, have your vehicle
inspected by an authorized Kia
dealer as soon as possible.
Engine Coolant Temperature WarningLight (if equipped)
This warning light illuminates:
When the engine coolant tempera- ture is above 120°C (248°F). This
means that the engine is overheat-
ed and may be damaged.
If your vehicle is overheated, refer
to "Overheating" in chapter 6.
Engine Oil Pressure
Warning Light
This warning light illuminates:
Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It remains on until the engine isstarted.
When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. Turn the engine off and check the engine oil level (For more details,
refer to "Engine Oil" in section 7). If
the level is low, add oil as required.
If the warning light remains on
after adding oil or if oil is not avail-
able, have your vehicle inspected
by an authorized Kia dealer as
soon as possible.
CAUTION - Engine
Overheating

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, with 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.

turned to the ON position.
Release the parking brake and make sure the brake warning light
goes off.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.

ACTIVE ECO SYSTEM (IF EQUIPPED)
Active ECO operation
Active ECO helps improve fuel effi-
ciency by controlling the engine and
transaxle. But fuel-efficiency can be
affected by the driver's driving habits
and road conditions.
When the Active ECO button is
pressed the ECO indicator (green)
will illuminate to show that the
Active ECO is operating.
When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn
off the system, press the active
ECO button again. If Active ECO is turned off, it will
return to the normal mode.
When Active ECO is activated:
The engine noise may get louder.
The vehicle speed may slightly bereduced.
The air conditioner performance may be affected.
Limitation of Active ECO oper-
ation:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
When the coolant temperature islow:
The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
the engine torque is restricted.
When using sports mode: The system will be limited accord-
ing to the shift location.
When the accelerator pedal is deeply pressed for a few seconds:
The system will be limited,as it has
determined that the driver has
accelerated judging that the driver
