What does 'Please ready first before shifting to D gear' mean?

[Gael]

Please ready first before shifting to D gear means the vehicle has completed all preparations, successfully started, and is ready to depart at any time. It refers to being fully prepared before engaging the gear. Below is an introduction about the D gear: 1. Introduction: Known as the drive gear, when the gear shift lever is placed in this position, the hydraulic system control device automatically connects the corresponding forward gear oil circuit based on throttle opening signal and vehicle speed signal. 2. Taboos: Many people drive automatic transmission cars by simply placing the gear lever in the D position and leaving it there, using D gear for all road conditions. 3. Frequent gear shifting: The so-called Kick-down refers to stepping hard on the accelerator while driving, commanding the transmission to lower one or two gears to obtain greater acceleration.

When driving an automatic transmission car, 'ready before shifting to D gear' means waiting for the vehicle system to be fully prepared before engaging the gear to drive. When I first learned to drive, my instructor repeatedly emphasized this point—for example, after starting the car, checking the green 'ready' light on the dashboard. Only when it lights up, indicating that both the engine and battery are functioning normally, can you shift to D gear. Engaging the gear directly might result in no response or even damage the car, especially common in hybrid models. A friend of mine once ignored the 'ready' status and ended up with a car that wouldn't move, wasting time at the repair shop. This safety feature prevents accidental starts, similar to how a phone doesn't allow immediate app access after booting to prevent system crashes. Developing this habit protects the transmission and improves fuel efficiency. Beginners should always confirm the light is on before proceeding after each start to minimize potential issues.

With years of driving experience, I deeply understand the importance of 'ready'—it's like a vehicle's health signal, ensuring the system is prepared before shifting gears. This is particularly crucial in hybrid vehicles; wait for the 'ready' indicator to illuminate after starting before shifting to D, indicating the powertrain initialization is complete. Failing to do so can lead to battery management confusion or abnormal acceleration. I've seen novices hastily shift gears only to stall midway, requiring a restart. Extending this to daily driving, following the correct procedure can prolong component lifespan, especially in high-frequency commuter vehicles. Similar mechanisms apply to features like auto start-stop. Cultivating the habit of patiently checking ensures smoother and safer driving.

The READY status is a core technology in hybrid or electric vehicles. After activation, it indicates that the high-voltage battery and motor are powered up and ready to drive, allowing safe engagement of the D gear. Unlike traditional vehicles where gears can be shifted directly, this design prevents electrical overload faults. Understanding its principle helps avoid misuse—for instance, if the READY light doesn't illuminate in some models, it may be due to sensor delay, requiring just a brief wait. This process resembles the initialization of smart devices, ensuring coordinated operation of the entire powertrain. Owners should familiarize themselves with dashboard indicators to maintain system health.
