Opening the fuel filler door
The fuel filler door must be opened
from inside the vehicle by pressing
the fuel filler door opener button.
If the fuel filler door does not open
because ice has formed around it,
tap lightly or push on the lid to break
the ice and release the lid. Do not pry
on the lid. If necessary, spray around
the lid with an approved de-icer fluid
(do not use radiator anti-freeze) or
move the vehicle to a warm place
and allow the ice to melt.1. Stop the engine.
2. To open the fuel filler door, push
the fuel filler door opener button.
3. Pull open the fuel filler door (1).
4. To remove the cap, turn the fuel filler cap (2) counterclockwise.
5. Refuel as needed.

WARNING
Before refueling, be sure to
check what type of fuel is used
for your vehicle.
If you put diesel fuel into a
gasoline-powered vehicle or
gasoline into a diesel-powered
vehicle, it may affect the fuel
system and cause serious dam-
age to the vehicle.

Engine Coolant Temperature
Gauge
This gauge indicates the tempera-
ture of the engine coolant when the
Engine Start/Stop button is ON.
If the gauge pointer moves beyond
the normal range area toward the “H”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “If the Engine
Overheats” in chapter 6.
Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
✽ ✽
NOTICE
• 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 - Hot radiator
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could cause severe
burns. Wait until the engine is
cool before adding coolant to
the reservoir.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine will probably be
too hot. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P and set
the parking brake. If the air condi-
tioning is on, turn it off.
3. If engine coolant is running out
under the vehicle or steam is com-
ing out from underneath the hood,
stop the engine. Do not open the
hood until the coolant has stopped
running or the steaming has
stopped. If there is no visible loss
of engine coolant and no steam,
leave the engine running and
check to be sure the engine cool-
ing fan is operating. If the fan is not
running, turn the engine off.4. Check to see if the water pump
drive belt is missing. If it is not
missing, check to see that it is
tight. If the drive belt seems to be
satisfactory, check for coolant
leaking from the radiator, hoses or
under the vehicle. (If the air condi-
tioning had been in use, it is nor-
mal for cold water to be draining
from it when you stop).
5. If the water pump drive belt is bro-
ken or engine coolant is leaking
out, stop the engine immediately
and call the nearest authorized
Kia dealer for assistance.6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. If coolant has been lost, care-
fully add coolant to the reservoir to
bring the fluid level in the reservoir
up to the halfway mark.
7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized Kia dealer for
assistance.
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized Kia
dealer.
WARNING - Under the
hood
While the engine is
running, keep hair,
hands and clothing
away from moving
parts such as the fan
and drive belts to pre-
vent injury.
WARNING - Radiator cap
Do not remove the
radiator cap when the
engine is hot. This may
result in coolant being
blown out of the open-
ing and cause serious
burns.

Maintenance
Air cleaner filter
A Genuine Kia air cleaner filter is rec-
ommended when the filter is replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance (if equipped)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized Kia dealer
should perform the operation.
Cooling system
Check the cooling system compo-
nents, such as the radiator, coolant
reservoir, hoses and connections for
leakage and damage. Replace any
damaged parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
But in severe conditions, the fluid
should be changed at an authorized
Kia dealer in accordance to the
scheduled maintenance at the begin-
ning of this chapter.
✽ ✽
NOTICE
Automatic transmission fluid color
is basically red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
CAUTION
Use only specified automatic
transmission fluid. The use of a
non-specified fluid could result
in a transmission malfunction
and failure. (Refer to
"Recommended lubricants and
capacities" in chapter 8.)

ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year: at
the beginning of the winter season,
and before traveling to a colder cli-
mate.Checking the coolant level Turn the engine off and wait until it
cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the cool-
ing system.
When you are sure all the pressure
has been released, press down on
the cap, using a thick towel, and
continue turning counterclockwise
to remove it.
Even if the engine is not operating,
do not remove the radiator cap or
the drain plug while the engine and
radiator are hot. Hot coolant and
steam may still blow out under
pressure, causing serious injury.
WARNING
Removing radiator
cap
Never attempt to remove the
radiator cap while the engine is
operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal injury
from escaping hot coolant or
steam.
CAUTION - Radiator cap
Never attempt to remove the
radiator cap while the engine is
operating or hot. Doing so
might lead to cooling system
and engine damage.

723
Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F and L marks on the
coolant level gauge when the engine
is cool.
If the coolant level is low, add enough
specified coolant to provide protec-
tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
see an authorized Kia dealer for a
cooling system inspection.
✽ ✽
NOTICE
Make sure the coolant cap is proper-
ly closed after refill of coolant.
Otherwise the engine could be over-
heated while driving.
1. Check if the radiator cap label is
on straight.WARNING- Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by engine coolant
temperature, refrigerant pres-
sure and vehicle speed. It can
operate even when the engine
is not running.
