Key Positions
Ignition Switch Positions
LOCK

The steering wheel locks to help protect against theft.
The ignition key can only be removed in the LOCK position. When the ignition is on, switch to the LOCK position, push the key in while in the ACC position, and turn the key to the LOCK position.
The steering column lock does not replace the parking brake.
Before leaving the driver's seat, always make sure the gear shift lever is in 1st gear for a manual transmission or P (Park) for an intelligent variable transmission, fully apply the parking brake, and turn off the engine.
ACC (Accessory)
The steering wheel is unlocked and electrical accessories can be operated.
If you have difficulty turning the ignition key to the ACC position, turn the key while turning the steering wheel left and right to relieve the tension.
ON
The warning lights can be checked before starting the engine. This is the normal operating position after the engine is started.
Do not leave the ignition in the ON position when the engine is not running, to prevent battery discharge.
START
Turn the ignition key to the START position to start the engine. The engine will crank until you release the key; it then returns to the ON position. The brake warning light can be checked in this position.
✽ NOTICE
If you leave the ignition key in the ACC or ON position for a long time, the battery may discharge.
WARNING - Ignition Switch
Never turn the ignition key to the LOCK or ACC position while the vehicle is moving. This may result in loss of steering control and braking function, which may cause an accident.
WARNING - Steering Wheel
Never reach through the steering wheel to operate any controls while the vehicle is moving. The presence of your hand or arm in this area may result in loss of vehicle control.
WARNING - Key Holder
Do not attach small wallets, multiple keys or any other heavy accessories to the key ring used to start the vehicle. This may cause the inserted key to unintentionally move the ignition to the ACC position while the vehicle is moving, thereby increasing the risk of an accident and deactivating several safety features.
WARNING - Exiting the Vehicle
To avoid unexpected or sudden vehicle movement, never leave the vehicle unless the transmission is locked in P (Park) and the parking brake is fully applied. Before leaving the driver's seat, always check that the lever is in P (Park), fully apply the parking brake, and turn off the engine.
