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.

Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
When assembling parts, be sure to
wipe the inside and outside of the
boot bottom of the ignition coil and
the insulator of the spark plug with a
soft cloth to prevent contamination of
the spark plug insulator.
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 (Engine / Inverter)
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Dual clutch transmission Fluid
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.

ENGINE OIL
Checking the engine oil level
Engine oil is used for lubricating,
cooling, and operating various
hydraulic components in the engine.
Engine oil consumption while driving
is normal, and it is necessary to
check and refill the engine oil regu-
larly. Also, check and refill the oil
level within the recommended main-
tenance schedule to prevent deterio-
ration of oil performance.
Check the engine oil following the
below procedure.1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to reach normal operating tempera-
ture. 3. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to
return to the oil pan.
4. Wipe the dipstick clean and rein- sert it fully.
5. Pull the dipstick out again and check the level. Check if the oil
level is between the F-L line, and if
it is below the L line, add enough
oil to bring the level to F line.
CAUTION
When you wipe the oil levelgauge, you should wipe it with aclean cloth.
When mixed with debris, it cancause engine damage.
WARNING- Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding engine oil as it may be
hot enough to burn you.

Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil.
(Refer to “Recommended lubricantsand capacities” in chapter 8.)
Do not spill engine oil when adding or changing engine oil. Wipe off
spilled oil immediately.
The engine oil consumption may increase while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles (6,000 km).
The engine oil consumption can be affected by driving habits, climate
conditions, traffic conditions, oil
quality, etc. Therefore, it is recom-
mended that you inspect the
engine oil level regularly and refill it
if necessary.Changing the engine oil and
filter
Have engine oil and filter changed by
an authorized Kia dealer according
to the Maintenance Schedule at the
beginning of this chapter.
If the maintenance schedule toreplace engine oil is exceeded, the
engine oil performance may deterio-
rate, and the engine condition may
be affected. Therefore, replace the
engine oil according to the mainte-
nance schedule.
To keep the engine in optimal condi- tion, use the recommended engine
oil and filter. If the recommended
engine oil and filter are not used
replace it according to the mainte-
nance schedule under severe usage
conditions.
The purpose of the maintenance schedule for engine oil replace-
ment is to prevent oil deterioration
and it is irrelevant to oil consump-
tion. Check and refill engine oil reg-
ularly.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.Periodically check that the fluid level
in the brake fluid reservoir is
between MIN and MAX. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsand capacities” in chapter 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
Brake fluid, which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
CAUTION - Brake fluid
Do not allow brake fluid to con-tact the vehicle's body paint, aspaint damage will result.
CAUTION - Proper fluid
Only use brake fluid in brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.

ENGINE CLUTCH ACTUATOR FLUID
Checking the engine clutch
actuator fluid level
In normal driving conditions, the
actuator fluid level does not go down
rapidly. However, oil consumption
rate may rise as vehicle mileage
increases, and leakage in actuator
related parts may result in increased
consumption of the engine clutch
actuator oil. Regularly check and
make sure the engine clutch actuator
oil fluid level is between [MIN] and
[MAX] marks.
If the oil level is below [MIN] mark,
we recommend that your vehicle be
checked by an authorized Kia dealer.If the fluid level is excessively low, we
recommend that the system be
checked by an authorized Kia dealer.
Use only the specified engine clutch
actuator fluid.
(Refer to “Recommended lubricants
or capacities” in chapter 8.)
Never mix different types of fluid.
✽ ✽
NOTICE - Loss of engine
clutch actuator fluid
In the event the engine clutch actua-
tor requires frequent additions of
fluid, we recommend that the system
be inspected by an authorized Kia
dealer.
WARNING- Engine clutch actuator fluid
When changing and adding
engine clutch actuator fluid,
handle it carefully. Do not let it
come in contact with your eyes.
If engine clutch actuator fluid
should come in contact with
your eyes, immediately flush
them with a large quantity of
fresh water, and seek medical
attention as soon as possible.
