How to safely turn the car engine on and off.
To ensure safe driving, drivers need to pay attention to basic principles, including starting and stopping the engine.
How to turn the car engine on and off correctly and safely.
Choose the most comfortable driving position: Positioning yourself comfortably while driving and adjusting your posture accordingly is crucial for enhancing driving safety and avoiding traffic violations.
For manual transmission vehicles, drivers need to follow these steps:
Depress the clutch pedal with your left foot.
Press the brake pedal with your right foot.
Set the gear lever to the N (Neutral) position.
Turn the key or press the start button to start the engine.
For automatic transmission vehicles, drivers need to follow these steps:
Make sure the gear lever is in the "P" (Parking) position.
Press the brake pedal with your right foot.
Turn the key or press the start button to begin operating the engine.
Things to note during the car starting process.
With a mechanical ignition lock, drivers need to follow these steps to start the vehicle:
Use the key to turn it past the two stops before pushing it into the final stop to start the engine.
Keep the key in place while the car starts.
Keep your hand on the key in the final position until you notice the engine has started, then release the key.
Avoid holding the key in place for too long after the engine has started to prevent damage to the starter motor.
With a push-button start, starting the engine is much simpler than with a mechanical key. Drivers need to follow these steps:
Press the brake pedal to ensure safety.
Press the start button to start the car.
The vehicle will be started using an electronic signal from the vehicle's electronic system.
For the latest car models, manufacturers have improved safety features and required a series of conditions for starting the engine. This helps reduce the risk during the starting process. However, the following points should still be noted:
For manual transmission vehicles: During startup, ensure the gear lever is in the correct position, especially not in first gear. Also, make sure the clutch pedal is fully depressed. This helps avoid unexpected situations and maintain control of the vehicle.
For older cars, especially manual transmissions: Ensuring the gear lever is in the correct position and the clutch pedal is fully depressed is crucial. If the engine is started while the gear lever is still in the first gear position and the clutch pedal is not fully depressed, the car may accelerate rapidly and become difficult to control, posing a danger to everyone around.
How long after starting the engine can the vehicle move?
When a vehicle has been turned off for an extended period, especially overnight, the engine needs to be "warmed up" before starting and driving. This ensures optimal engine performance and prevents unnecessary malfunctions. When the engine is warm, sufficient engine oil is pumped into the combustion chamber, enhancing lubrication and protecting critical components.
The proper engine warm-up time is typically around 30-40 seconds in normal weather conditions. If the temperature is very low, the warm-up time may be longer. Most modern vehicles are designed to automatically increase the engine speed to a high level (around 2,000 rpm) if the engine is not yet warm enough, and after a short time, the engine will return to normal operation with a speed below 1,000 rpm. At this point, you can start and drive normally.
When the vehicle is only stopped and switched off for short periods during the day, warming up the engine before driving is unnecessary.
At the same time, prolonged engine idling is not recommended. When the vehicle is idling and the engine does not reach its full operating temperature, acids and moisture may not evaporate completely, accumulating on the cylinder surfaces and causing engine corrosion. This can affect engine performance and lifespan.
Turn off the engine properly.
Turning off the air conditioner a few minutes before the end of the journey can help your body gradually adjust to the outside temperature and avoid thermal shock. Additionally, turning off the air conditioner and running the fan during the final minutes of the trip can help dry the air vents, preventing moisture buildup and mold formation that causes unpleasant odors. At the same time, turning off the air conditioner before the end of the trip can also help save fuel.
When parking and finishing a journey, some guides recommend letting the engine idle for about 30 seconds before completely shutting it off. This is especially important for vehicles equipped with turbochargers. During long journeys, some engine components, such as the turbocharger, can become hotter than others. When the engine is shut off immediately, the flow of oil in the engine stops, causing hot oil to concentrate in the turbocharger components. This can cause oil degradation and reduce its lubricating properties.
Allowing the engine to idle before shutting it off allows the oil to distribute evenly throughout the engine and helps reduce oil degradation. However, note that specific timings and usage instructions may vary depending on the vehicle type and manufacturer. Refer to your owner's manual and manufacturer's information for proper handling and maintenance of your vehicle's engine.
