Door, hood, liftgate, or sunroof open

For your safety, the Kia K4 LCD display provides an immediate warning if a door, the hood, the rear liftgate, or the sunroof is not securely closed. The visual indicator will clearly pinpoint which specific area requires your attention, allowing you to secure the Kia K4 before driving.

Lights mode

Exterior Lights status indicator

This indicator provides real-time feedback on which exterior light setting is currently selected via the Kia K4 lighting control stalk.

When the windshield washer fluid reservoir in your Kia K4 reaches a critically low level, this warning message will appear on the LCD. We recommend refilling the reservoir promptly with high-quality washer fluid to ensure optimal visibility in all driving conditions.

Engine overheated

Engine temperature warning alert

This is a critical alert for your Kia K4. If this warning appears, it means the engine temperature has exceeded the safe operating limit. For the longevity of your Kia K4, you should stop the vehicle in a safe location immediately and allow the engine to cool down, or contact roadside assistance.

This critical warning message appears on the Kia K4 instrument cluster when the engine coolant temperature exceeds 248°F (120°C). This indicates that the engine has severely overheated, and continued operation may cause permanent, irreversible damage to your Kia K4 engine components.

If your vehicle displays this alert, you must pull over safely and refer to the "If the engine overheats" section of your owner's manual immediately.

Icy road warning

Ice possible. Drive with care.

This safety warning in the Kia K4 is designed to alert the driver to potential ice accumulation on the road surface. Whenever the outside temperature gauge detects conditions below approximately 40°F (4°C), the warning light and the temperature readout will blink 5 times, then remain illuminated. Simultaneously, a single warning chime will sound to capture your attention.
