What are the hidden features of the 9th-gen Civic's small screen?

The hidden feature of the 9th-gen Civic's small screen is that pressing the Source and Menu buttons on the left side of the steering wheel simultaneously will trigger an Easter egg. Taking the 2012 9th-gen Civic 1.8L Manual Comfort Edition as an example: This vehicle is manufactured by Dongfeng Honda, classified as a compact car with gasoline power. It has a maximum power output of 104kW, maximum torque of 174Nm, and comes with a 5-speed manual transmission. The car measures 4535mm in length, 1755mm in width, and 1450mm in height, with a wheelbase of 2670mm. It's a 4-door, 5-seater sedan with a 5-speed manual transmission, capable of reaching a top speed of 199km/h, and features naturally aspirated intake.

I've been driving a ninth-gen Civic, and this small screen has quite a few hidden features worth exploring. First, you can enter the engineering mode with a simple button combination: turn the key to the ACC position without starting the engine, then press and hold the reset and setup buttons on the dashboard for about 10 seconds. The small screen will then display a hidden menu. Inside, you can view various useful data, such as battery voltage (shows the current battery status—below 12.5V means it might be running low), engine runtime (records the total operating hours of the vehicle), and coolant temperature (if it rises abnormally, it indicates engine overload issues). This feature was originally intended for mechanics to diagnose problems, but now owners can easily use it too. I often use it to check my car's health and avoid breakdowns on the road. Another fun feature is the ability to adjust settings, like switching units from kilometers to miles or setting warning thresholds. Just remember not to tamper with core parameters to avoid affecting system stability. Overall, this is a valuable Easter egg that makes daily driving smarter.

As someone who frequently tinkers with cars, I particularly enjoy exploring the hidden modes of the ninth-generation Civic's small screen. The method is straightforward: while the car is parked, press a combination of buttons like the reset and up adjustment keys for a few seconds to enter the diagnostic interface. The information displayed is incredibly useful, such as showing the battery voltage, which helps you gauge the remaining lifespan of the battery, and engine error codes—if a red light flashes, you can address the issue before it worsens. I once used this feature to detect a coolant problem, which I fixed in time and saved a lot of money. Additionally, some versions allow you to fine-tune alarm volumes or display brightness, enhancing driving comfort. Be cautious when operating, and avoid altering sensitive data, as this mode is designed for vehicle maintenance. In short, this hidden menu makes the car feel more like a smart device. I recommend giving it a try, but consult the manual to avoid mistakes.

The hidden functions of the 9th-gen Civic's small screen are mainly diagnostic-related. I've tried entering the engineering mode with button combinations, which displays battery voltage and system status—very helpful for routine maintenance. For example, it allows changing the battery in advance if the voltage is too low, avoiding roadside failures. It also shows engine parameters like abnormal coolant temperature. Simple to operate but highly practical.
