Driving your vehicle
The use of chains may adverselyaffect 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 section 7. Never attempt to check
the Hybrid High Voltage Battery. 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 igni-
tion 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.

RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute
to fuel economy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements
are difficult to measure in everyday driving, but in a year’s time, they can offer significant cost and energy savings.

3If the API service SM engine oil is not available in your country, you are able to use API service SL.

Recommended SAE viscosity
numberEngine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather.Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle
will be operated in before the next oil
change. Proceed to select the rec-
ommended oil viscosity from the
chart.
CAUTION
Always be sure to clean the area
around any filler plug, drainplug, or dipstick before check-ing or draining any lubricant.This is especially important industy or sandy areas and whenthe vehicle is used on unpavedroads. Cleaning the plug anddipstick areas will prevent dirtand grit from entering theengine and other mechanismsthat could be damaged.

*1. For better fuel economy, it is recommended to use the engine oil of
a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However, if
the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.
