Hyundai Tucson: Driving Your Vehicle / Key Ignition Switch


To reduce the risk of serious injury or death:

  • Never allow children or any person who is unfamiliar with the vehicle to touch the ignition switch or related parts. Unexpected and sudden vehicle movement may occur.
  • Never reach through the steering wheel for the ignition switch, or any other control, while the vehicle is moving. The presence of your hand or arm in this area may cause a loss of vehicle control resulting in a collision.

A: Lock, B: ACC, C: ON, D: START

Whenever the front door is opened, the ignition switch illuminates if the ignition switch is not in the ON position. The light goes off immediately when the ignition switch is turned ON or goes off after about 30 seconds when the door is closed. (for vehicles equipped with ignition switch illumination)


  • Never turn the ignition switch to the LOCK or ACC position while the vehicle is moving except in an emergency. This may result in the engine turning off and loss of power assist for the steering and brake systems. This may cause loss of directional control and braking function, which could cause a collision.
  • Before leaving the driver's seat, always make sure the shift lever is in the P (Park) position, apply the parking brake, turn the ignition switch to the LOCK position, and take the keys with you to prevent unintended vehicle movement.


Never use aftermarket keyhole covers. These covers may prevent the vehicle from recognizing the key and not allow the vehicle to start.
