*1 Fuel additives

If TOP TIER Detergent Gasoline is unavailable, Kia recommends adding one bottle of approved fuel additive at the specified interval. These additives are available from authorized Kia dealers along with detailed usage instructions. Do not mix different types of fuel additives.

*2 Engine oil and engine oil filter

It is normal for a Kia Seltos engine to consume a small amount of engine oil during operation. Check the engine oil level regularly and top up when necessary.

The engine oil replacement interval for normal driving conditions is based on the use of the recommended Kia engine oil specification. If a different oil specification is used, replace the engine oil and filter according to the severe usage maintenance schedule.

Never add aftermarket additives to the engine oil. Such products may alter the oil's properties and could result in serious engine damage or reduced engine durability.

For maximum performance and long-term reliability, always use genuine Kia parts and approved lubricants when servicing your Kia Seltos. Regular maintenance helps preserve fuel efficiency, emissions performance, and overall driving safety.

*3 Coolant

When adding coolant to your Kia Seltos, use only deionized water or soft water. Never mix hard water with the factory-filled coolant. An incorrect coolant mixture may cause serious engine malfunction, cooling system damage, or reduced long-term engine protection.

*4 Drive belts (Engine)

Inspect the alternator, water pump, and air conditioner drive belts. If necessary, have them adjusted, repaired, or replaced. The drive belt tensioner, idler pulley, and alternator pulley should also be checked and corrected or replaced when wear, noise, or improper tension is found.

*5 Differential oil

If your Kia Seltos has been submerged in water or driven through a flooded area, the differential oil should be changed as a precaution to prevent internal damage.

*6 Transfer case oil

If the Kia Seltos has been submerged in water or exposed to flooding, the transfer case oil should be replaced as a preventive measure.

* Transmission fluid

If the vehicle has been submerged in water or driven through deep flooding, the transmission fluid should be changed as a precaution. Water contamination can seriously affect transmission durability and operation.

Fuel filter (Gasoline engine)

The fuel filter in the gasoline engine is normally maintenance-free, but periodic inspection is recommended during scheduled maintenance, especially if poor fuel quality is suspected.

If safety-related symptoms occur, such as restricted fuel flow, engine surging, loss of power, difficult starting, or unstable operation, replace the fuel filter immediately regardless of the maintenance schedule. Consult an authorized Kia dealer for proper diagnosis and service.

Severe Driving Conditions

A: Repeated short-distance driving of less than 5 miles (8 km) in normal temperatures, or less than 10 miles (16 km) in freezing temperatures.

B: Extended low-speed driving over long distances.

C: Driving on rough, dusty, muddy, unpaved, gravel, or salt-covered roads.

D: Driving in areas where road salt or other corrosive materials are used, or operating the Kia Seltos in very cold weather.

E: Driving in heavy dust conditions.

F: Driving regularly in heavy traffic areas.

G: Repeated driving on uphill, downhill, or mountain roads.

H: Using the Kia Seltos for towing, camping, or driving with cargo loaded on the roof.

I: Using the vehicle as a patrol car, taxi, commercial vehicle, or for frequent towing.

J: Frequent high-speed driving or repeated rapid acceleration and deceleration.

K: Frequent stop-and-go driving.

When the Kia Seltos is used under any of these severe conditions, maintenance should be performed more often to help protect the engine, transmission, AWD components, brakes, and suspension from accelerated wear.
