If it fits loosely, we recommend that
you consult an authorized Kia dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you
may not need for operating the vehicle,
such as the cigarette lighter fuse.
If the headlights or taillights, stop lights, courtesy lamp, day time running
lights (D.R.L) do not work and the fuses
are OK, check the fuse panel in the en‐ gine compartment. If a fuse is blown, it
must be replaced.

Maintenance

• If you use unauthorized electronicdevices, it may cause the vehicle to
operate abnormally, wire damage, battery discharge and fire. For your
safety, do not use unauthorized elec‐
tronic devices.
Engine exhaust gas precautions
(carbon monoxide)
• Carbon monoxide can be present with other exhaust fumes. Therefore, if
you smell exhaust fumes of any kind inside your vehicle, have it inspected
and repaired immediately. If you ever
suspect exhaust fumes are coming
into your vehicle, drive it only with all
the windows fully open. Have your vehicle checked and repaired immedi‐
ately.
WARNING
nExhaust
Engine exhaust gases contain carbonmonoxide (CO). Though colorless andodorless, it is dangerous and couldbe lethal if inhaled. Follow the in‐structions on this page to avoid COpoisoning.
• Do not operate the engine in confined or closed areas (such as garages) any
more than what is necessary to move the vehicle in or out of the area.
• When the vehicle is stopped in an open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to
draw outside air into the vehicle.
• Never sit in a parked or stopped vehi‐ cle for any extended time with the
engine running.
• When the engine stalls or fails to start, excessive attempts to restart
the engine may cause damage to the
emission control system.
Operating precautions for catalytic
converters (if equipped)
WARNING
nFire
(Continued)
(Continued)
•A hot exhaust system can igniteflammable items under your vehi‐cle. Do not park the vehicle over ornear flammable objects, such asgrass, vegetation, paper, leaves,etc.
•The exhaust system and catalyticsystem are very hot while the en‐gine is running or immediately af‐ter the engine is turned off. Keepaway from the exhaust systemand catalytic, you may get burned.Also, do not remove the heat sinkaround the exhaust system, donot seal the bottom of the vehicleor do not coat the vehicle for cor‐rosion control. It may present afire risk under certain conditions.
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions must be observed: • Make sure to refuel your vehicle ac‐ cording to the L

Recommended SAE viscosity number
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.
