What are the precautions for automatic transmission cars?
3 Answers
There are four main precautions for automatic transmission cars: 1. Gear shifting during driving: Automatic transmission cars have protection and interlock for dangerous actions. 2. Rolling back on slopes: If an automatic transmission car is parked on a steep slope where gravity exceeds the power "margin" at idle, the car may roll back. Therefore, the handbrake should be used when starting. 3. Do not coast in neutral: Prolonged coasting in neutral can lead to insufficient oil pressure in the hydraulic lines of the automatic transmission, increasing friction, reducing lubrication effectiveness, and damaging the friction plates inside the transmission. 4. Pay attention to parking gear: When parking or idling for a long time in an automatic transmission car, first press the brake, shift to N gear, then engage the handbrake and release the brake pedal. Once the car is completely stopped, shift to P gear.
Driving an automatic transmission car is quite smooth, but there are some small details to pay attention to. Before starting the engine, make sure the gear is in P (Park) to prevent rolling. After starting, press the brake and shift to D (Drive) to move off—don’t rush to stomp on the accelerator to avoid damaging the transmission. Try to maintain a steady speed while driving and avoid frequent gear shifts, as sudden acceleration or braking can increase wear on components. When parking, shift to N (Neutral), engage the handbrake, then shift to P (Park) before turning off the engine—especially on slopes, this protects the transmission’s locking mechanism. Don’t forget to regularly check the transmission fluid; it’s usually replaced every 50,000 km, and if it turns black or has a burnt smell, it’s time for a change. During long traffic jams, avoid keeping the brake pressed—shifting to N (Neutral) reduces heat buildup. In short, developing good driving habits extends your car’s lifespan.
Safety comes first when driving. Automatic transmission vehicles offer high convenience, but safety measures must be observed. Before starting, ensure the gear is in P (Park) and press the brake to start the engine. When shifting gears while driving, be decisive without hesitation—for example, shifting from R (Reverse) to D (Drive) must be done after the vehicle has come to a complete stop. Avoid coasting in neutral; when going downhill, keeping the gear in D and relying on engine braking provides better stability. Do not operate the gearshift while distracted by using auxiliary equipment such as light switches or wipers. Regularly check tire pressure and the brake system to ensure timely response in emergencies. If a warning light comes on, pull over immediately for inspection—never force the vehicle to continue. Cultivate the habit of constantly checking the rearview mirror, as safe driving is paramount.
