Engine Coolant Temperature
Gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or 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.OJF048134L
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.

When ECO mode is activated:
The acceleration response may be
slightly reduced if the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The shift pattern of the automatic transmission may change.
The engine noise may get louder.
The above situations are normal
conditions when ECO mode is acti-
vated to improve fuel efficiency. Limitation of ECO mode operation:
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
When the coolant temperature is
low:
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
engine torque is restricted.

The use of chains may adversely
affect vehicle handling.
Do not exceed 20 mph (30 km/h) or the chain manufacturer’s recom-
mended speed limit, whichever is
lower.
Drive carefully and avoid bumps, holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.
Avoid sharp turns or locked-wheel braking.Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.CAUTION- Snow chains
Chains that are the wrong size or improperly installed candamage your vehicle's brakelines, suspension, body andwheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

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 soonas it is safe to do so.
2.Place the shift lever in P (for Automatic transmission / Dual
clutch transmission) and set the
parking brake. If the air condition-
ing 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 leak-
ing 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
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 side
of the coolant reservoir 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.
Recommended engine coolant
When adding coolant, use onlydeionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze. This would
reduce the effectiveness of the
solution.
OJF075006
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 may
sometimes operate even when
the engine is not running.

Temperature -A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law. Tire terminology and definitions
Air Pressure:
The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
kilopascal (kPa) or pounds per
square inch (psi).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic transmis-
sion, power seats, and air condition-
ing.
Aspect Ratio: The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire: A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread. Cold Tire Pressure:
The amount of
air pressure in a tire, measured in
kilopascals (kPa) or pounds per
square inch (psi) before a tire has
built up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: A code molded into
the sidewall of a tire signifying that
the tire is in compliance with the U.S.
Department of Transportation motor
vehicle safety standards. The DOT
code includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.
