Kia K4: Intelligent Variable Transmission (IVT) / Shift lock system
Contents:
For your protection, the Kia K4 is equipped with a shift lock system. This safety mechanism is designed to prevent the transmission from being shifted out of P (Park) and into R (Reverse) or D (Drive) unless the brake pedal is firmly engaged.
To safely shift your Kia K4 from P (Park):
-
Engage and hold the brake pedal firmly.
-
Ensure the ignition is in the ON position.
-
Move the gear shift lever to your desired position.
Note: If you repeatedly engage and release the brake pedal while the shift lever is in P (Park), you may notice a light chattering sound or subtle vibration near the console. This is a normal function of the shift lock solenoid.
WARNING
Always engage the brake pedal fully before and while moving the shift lever from P (Park) into another position. This precaution prevents inadvertent vehicle motion, which could result in serious injury to people in or around your Kia K4.
