Headlamp Warning Light
Continuous driving with the LED Headlamp Warning Lighton or blinking can reduce LEDheadlamp (low beam) life.

Driving your vehicle

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 8. 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 8. 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 9 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 8 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.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Turn on the emergency warning
flasher and stop in a safe place.
Move the shift lever to P (Park)
and engage the parking brake.
2. If hot steam does not come out from the engine room, carefully
open the engine room and check
whether the water pump connec-
tor is properly engaged. If the con-
nector is not properly engaged,
stop the engine immediately and
properly engage the connector.
Then, turn the engine on.
3. Turn on the air conditioner. 4. If the “HEV Warning” light turns on
in the driver instrument cluster, or
engine coolant or hot steam emits
from the engine coolant filler, stop
the engine immediately. Then, call
the nearest authorized Kia dealer
for assistance. If the “Engine
Warning” light remains illuminated
or the engine coolant is not flowing
out, keep the engine running.
Open the engine hood for ventila-
tion to help cool down the engine. 5. Check whether the engine coolant
temperature is low enough by
checking its temperature. If the
engine coolant level is low, please
check the connecting parts
between the radiator hose, heater
hose, and water pump for any
signs of leakage. When there is no
sign of leakage, please refill the
engine coolant. If causes and
signs of engine overheating such
as warning light illumination,
engine coolant leakage, or cooling
fan malfunction are found, stop the
vehicle the earliest. Then, call the
nearest authorized Kia dealer for
assistance.
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.

What to do in an emergency
6. If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir 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 over heating happens again,
call the nearest authorized Kia
dealer for assistance.
✽ ✽NOTICE
Serious loss of coolant indicates
there is a leak in the cooling system
and should be checked as soon as
possible by an authorized Kia dealer.
CAUTION
When the engine overheats from
low engine coolant, suddenlyadding engine coolant maycause cracks in the engine. Toprevent damage, add enginecoolant slowly in small quantities
WARNING- Radiator Cap
Do not remove the
radiator cap when the
engine is hot. This
can allow coolant to
blow out of the open-
ing and cause seri-
ous burns.

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.
The engine coolant and/or inverter
coolant level is influenced by the
hybrid system temperature. Before
checking or refilling the engine
coolant and/or inverter coolant,
turn the hybrid vehicle off.
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 theradiator cap while the engine isoperating or hot. Doing somight lead to cooling systemand engine damage.
