•Drive carefully and avoid bumps,holes, sharp turns, and other roadhazards, which may cause the ve‐hicle to bounce.
•Avoid sharp turns or locked wheelbraking.
CAUTION
•Chains that are the wrong size orimproperly installed can damageyour vehicle's brake lines, suspen‐sion, body and wheels.
•Stop driving and retighten thechains any time you hear themhitting the vehicle.
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high quali‐ty 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 cooling sys‐
tem, lubricates the water pump and
prevents freezing. Be sure to replace or replenish your coolant in accordance
with the L

Use approved window washer
anti-freeze in system
To keep the water in the window wash‐er system from freezing, add an ap‐
proved window washer anti-freeze sol‐
ution in accordance with instructions on the container. Window washer anti-
freeze is available from an authorized
Kia dealer and most auto parts outlets. Do not use engine coolant or other
types of anti-freeze as these may
damage the paint finish.
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged posi‐ tion. This is most likely to happen when
there is an accumulation of snow or ice
around or near the rear brakes or if the brakes are wet. If there is a risk the
parking brake may freeze, apply it only
temporarily while you put the shift lev‐ er in P (Automatic Transaxle / Dual
clutch transmission) or in first or re‐
verse gear (manual transaxle) and block
the rear wheels so the vehicle cannot roll. Then release the parking brake.
Don't let ice and snow
accumulate underneath
Under some conditions, snow and ice can build up under the fenders and in‐
terfere with the steering. When driving
in severe winter conditions where this may happen, you should periodically
check underneath the vehicle to be sure
the movement of the front wheels and the steering components is not ob‐
structed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropriate emergency equipment. Some of the
items you may want to carry include
tire chains, tow straps or chains, flash‐ light, emergency flares, sand, shovel,
jumper cables, window scraper, gloves,
ground cloth, coveralls, blanket, etc.

CAUTION
•Serious loss of coolant indicatesthere is a leak in the cooling sys‐tem and we recommend that thesystem be checked by an author‐ized Kia dealer.
•When the engine overheats fromlow engine coolant, suddenly add‐ing engine coolant may causecracks in the engine. To preventdamage, add engine coolant slowlyin small quantities.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per‐
formed at the frequencies indicated to help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties
and you may be charged for labor, parts and lubricants used.
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check the coolant level in the coolant reservoir.
• Check the windshield washer fluid level.
• Look for low or under-inflated tires.
WARNING
Be careful when checking your en‐gine coolant level when the engine ishot. Scalding hot coolant and steam

may blow out under pressure. Thiscould cause burns or other seriousinjury.
While operating your vehicle:
• Note any changes in the sound of the exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-
ahead position.
• Notice if your vehicle constantly turns slightly or L

NORMAL MAINTENANCE SCHEDULE - FOR GASOLINE ENGINE [FOR EUROPE (EXCEPT RUSSIA)]
The following maintenance services must be performed to ensure good emission control and performance. Keep receipts for
all vehicle emission services to protect your warranty. Where both mileage and time are shown, the frequency of service is determined by whichever occurs first.
NO.ITEMREMARK
*1 Coolant (Engine / Inverter) When adding coolant, use only deionized water or soft water for your vehicle
and never mix hard water in the coolant filled at the factory. An improper
coolant mixture can result in serious malfunction or engine damage.
*2 Engine oil and engine oil filter Check the engine oil level and leak every 500 km (350 miles) or before start‐ing a long trip.
*3 Fuel additives (Gasoline) Kia recommends that you use unleaded gasoline which has an octane rating
of RON (Research Octane Number) 95 / AKI (Antiknock Index) 91 or higher
(for Europe) or Octane Rating of RON (Research Octane Number) 91 / AKI(Antiknock Index) 87 or higher (except Europe).
For customers who do not use good quality gasolines including fuel additives
regularly, and have problems starting or the engine does not run smoothly,
one bottle of additives added to the fuel tank at every 15,000 km (for Eu‐rope, Australia and New Zealand)/10,000 km (except Europe, Australia andNew Zealand).
Additives are available from your authorized Kia dealer along with informa‐
tion on how to use them. Do not mix other additives.
*4 HSG (Hybrid Starter & Generator) belt Inspect HSG belt for evidence of cuts, crocks, excessive wear or oil saturation
and replace if necessary. If drive belt noise occurred, readjust drive belt ten‐
sion before replace.
*5 Spark plug For your convenience, it can be replaced prior to it's interval when you domaintenance of other items.
