  2. Set speed

The Manual Speed Limit Assist (MSLA) system is a helpful tool for your Kia Carnival, allowing you to set a maximum speed limit when you wish to avoid driving above a specific velocity. If you exceed this preset limit, the system activates by flashing the limit indicator and emitting an audible chime until your Kia Carnival speed returns to or falls below the designated limit.

Manual Speed Limit Assist operation

Setting speed limit

  1. While driving at your desired speed, press and hold the Driving Assist button (Kia Carnival Driving Assist button icon). The Speed Limit indicator (Kia Carnival Speed Limit symbol) will appear on your cluster.

  2. Push the (+) switch up or the (-) switch down to adjust your speed settings. Briefly pushing the switch increments the speed; holding it will increase or decrease the limit to the nearest multiple of 5 mph (10 km/h) initially, followed by 5 mph (10 km/h) increments thereafter.

  3. Once set, the speed limit is displayed on your Kia Carnival cluster. If you need to accelerate beyond the preset limit—such as during an overtaking maneuver—firmly depress the accelerator pedal. The indicator will blink and a warning chime will sound until the Kia Carnival returns to a speed within the set limit.

  • As long as the accelerator pedal is not pressed beyond the resistance point, your Kia Carnival will maintain the set speed.

  • Depending on your specific Kia Carnival trim and regional features, the maximum allowable speed setting may vary. You cannot increase the limit beyond the factory-defined maximum.

If you push the (+) switch up or the (-) switch down, the Kia Carnival will adopt your current driving speed as the new limit, which will be updated and displayed on the instrument cluster.

Alternatively, if you press the resume button (Kia Carnival resume button for speed limit assist), your Kia Carnival will automatically revert to the previously stored speed limit setting.

To ensure a safe driving experience while using the Manual Speed Limit Assist in your Kia Carnival, please observe the following precautions:

  • Always calibrate your vehicle's speed limit setting to remain within the legally posted traffic speed limits for the road you are currently traveling on.

  • Keep the Manual Speed Limit Assist system turned off when it is not actively required to prevent unintentional speed restrictions. Always verify that the Speed Limit indicator (Kia Carnival speed limit indicator light) is extinguished when the system is not in use.

  • Remember that the Manual Speed Limit Assist is a driver-aid, not a substitute for attentive and safe driving. The driver retains full responsibility for vehicle control, maintaining awareness of sudden changes in traffic conditions, and strictly monitoring the road ahead at all times.
