What are the different positions of a car key?

[NevaehAnn]

Detailed introduction is as follows: 1. LOCK position: This is where the key is inserted and removed. At this position, all circuits are completely turned off except for the anti-theft system and interior small lights, and the steering wheel is locked. 2. ACC position: Accessory power-on position. When the key is turned to this position, the accessory circuit is activated, allowing devices like the radio to function. 3. ON position: Power-on position. When the key is turned to this position, all vehicle circuits are activated, and the system prepares for engine start-up with necessary procedures and self-checks. The key remains in this position during normal driving. 4. START position: Engine start position. When the key is turned to this position, the starter circuit is activated, causing the engine to crank and start. Upon releasing the key, it automatically returns to the ON position. Additional information: These four positions are progressive, designed to allow electrical devices to enter operation one by one, thereby alleviating the burden on the car battery caused by instantaneous power-on.

Having driven for over a decade, I've found that key positions are quite particular. LOCK is the parking position - removing the key locks the steering wheel to prevent theft; ACC is the accessory position where you can turn on the radio or use the cigarette lighter without starting the engine, saving power; ON is the ignition position where dashboard lights illuminate for vehicle pre-checks, but don't leave it too long to avoid draining the battery; START activates the engine to get the car moving. I remember a friend once left it in ON position all day and completely drained the battery, costing unnecessary money for replacement. These designs prioritize both safety and energy efficiency - always develop the habit of returning to LOCK when parked. Many modern cars now use push-button start systems, but the position principles remain similar - simple yet practical.

When I first got my driver's license, I often got confused about the key positions. The ACC position is super convenient—you can relax and listen to music or charge your phone before driving. The ON position powers up the entire car but doesn't move it, so you need to quickly turn to START to ignite the engine. After starting, it automatically returns to ON. LOCK is the parking and locking position—not locking it could make your car an easy target for theft. Once, I accidentally left it in ON for several hours and got a scare when the car wouldn't start. I recommend beginners memorize the sequence: LOCK when exiting, ACC for breaks, ON for checks, and START to drive. Don't overlook the ACC position—it's perfect for using the AC outlet to brew coffee during weekend picnics, which is super thoughtful. Developing a habit of locking your car is crucial—safety first, and it also reduces battery drain.

Car key positions actually come in four types: LOCK secures the vehicle against theft; ACC provides power to accessory electronics, suitable for listening to the radio while parked; ON activates the dashboard without starting the engine; START ignites the vehicle. Each position controls different functions, and if faulty, it may get stuck in ON or have poor contact in LOCK. Dust tends to accumulate with prolonged use, so regularly cleaning the keyhole can prevent issues. Always turn back to LOCK when parking to save power and ensure safety.
