Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery. • If the battery becomes discharged in a short time (because, for example,the headlights or interior lights were
left on while the vehicle was not in
use), recharge it by slow charging
(trickle) for 10 hours.
• If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge it
at 20-30A for two hours.
WARNING
nRecharging battery
When recharging the battery, ob‐serve the following precautions:•The battery must be removedfrom the vehicle and placed in anarea with good ventilation.
•Do not allow cigarettes, sparks, orflame near the battery.
•Watch the battery during charg‐ing, and stop or reduce the charg‐ing rate if the battery cells begingassing (boiling) violently or if thetemperature of the electrolyte ofany cell exceeds 49°C (120°F).
•Wear eye protection when check‐ing the battery during charging.
•Disconnect the battery charger inthe following order.1.Turn off the battery chargermain switch.
2.Unhook the negative clampfrom the negative battery ter‐minal.
3.Unhook the positive clamp fromthe positive battery terminal.
WARNING
•Before performing maintenance orrecharging the battery, turn off allaccessories and stop the engine.
•The negative battery cable mustbe removed first and installed lastwhen the battery is disconnected.
•Operation related to the battery isrecommended to an authorized Kiadealer.
CAUTION
•Keep the battery away from wa‐ter or any liquid.
•For your safety, we recommendthat you use parts for replace‐ment from an authorized Kia deal‐er.
Reset items
Items should be reset after the battery
has been discharged or the battery has been disconnected. • Auto up/down window (if equipped)
• Sunroof (if equipped)
• Trip computer

Maintenance

Don't neglect the interior
Moisture can collect under the floor
mats and carpeting and cause corro‐
sion. Check under the mats periodically to be sure the carpeting is dry. Use
particular care if you carry fertilizers,
cleaning materials or chemicals in the vehicle.
These should be carried only in proper
containers and any spills or leaks
should be cleaned up, flushed with clean water and thoroughly dried.
Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand cleaner, and air freshener from contacting the
interior parts because they may cause
damage or discoloration. If they do con‐ tact the interior parts, wipe them off
immediately. If necessary, use a vinyle
cleaner, see instructions for correct us‐ age.
CAUTION
Never allow water or other liquids tocome in contact with electrical/elec‐
(Continued)
(Continued)
tronic components inside the vehicleas this may damage them.
CAUTION
When cleaning leather products(steering wheel, seats etc.), useneutral detergents or low alcoholcontent solutions. If you use high al‐cohol content solutions or acid/alka‐line detergents, the color of theleather may fade or the surface mayget stripped off.
Cleaning the upholstery and
interior trim
Vinyl
Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner. Clean vinyl surfaces with a vinyl clean‐
er.
Fabric
Remove dust and loose dirt from fabric
with a whisk broom or vacuum cleaner. Clean with a mild soap solution recom‐
mended for upholstery or carpets. Re‐
move fresh spots immediately with a fabric spot cleaner. If fresh spots do
not receive immediate attention, fabric
can be stained and its color can be af‐ fected. Also, its fire-resistant proper‐
ties can be reduced if the material is
not properly maintained.
CAUTION
Using anything but recommendedcleaners and procedures may affectthe fabric’s appearance and fire-re‐sistant properties.
Cleaning the lap/shoulder belt
webbing
Clean the belt webbing with any mild
soap solution recommended for clean‐ ing upholstery or carpet. Follow the in‐
structions provided with the soap. Do
not bleach or re-dye the webbing be‐ cause this may weaken it.

CAUTION
Always be sure to clean the area around any filler plug, drain plug, or dipstick before checking or draining any lubricant.This is especially important in dusty or sandy areas and when the vehicle is used on unpaved roads. Cleaning the plug anddipstick areas will prevent dirt and grit from entering the engine and other mechanisms that could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather operating (engine start and engine oil flowabil‐
ity). Lower viscosity engine oils can provide better fuel economy and cold weather performance, however, higher viscosity en‐ gine oils are required for satisfactory 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 recommended oil vis‐ cosity from the chart.

*1 : For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-30 (ACEA A5). However, if
the engine oil is not available in your country, select the proper engine oil using the engine oil viscosity chart.
