Automatic driving common misunderstanding

People are already familiar with the use of manual transmissions and are relatively easy to use. But for automatic cars, people are less likely to use them. In the use of automatic vehicles, there is a considerable number of owners who lack awareness of automatic transmissions, and use manual transmissions to operate automatic transmissions, resulting in vehicle damage, degraded vehicle performance, and shortened life. The following are common mistakes in driving an automatic car. Hopefully, it will help the majority of owners to go out of their use mistakes.

Myth # 1: D-stop when parking for a long time

When a vehicle equipped with an automatic transmission is jammed, some owners often only depress the brake pedal and the shift lever stays in the D range (drive range) and does not shift. If the time is short, this is allowed. However, if parking time is long, it is better to swap in N (neutral) and tighten the parking brake. Because the shift lever is in the D range, the automatic transmission car generally has a slight forward movement. If the brake pedal is pressed for a long time, it is equal to forcibly stopping this forward movement, so that the oil temperature of the transmission is increased, and the oil is easily deteriorated, especially in When the air conditioning system is operating, it is more unfavorable for the engine to have a higher idle speed.

Myth 2: Hanging N-blocks at high speeds or downhill
In order to save fuel, some drivers shift the shift lever to N (neutral) when driving at high speed or downhill, which is likely to burn the transmission. Because at this time, the output shaft speed of the transmission is very high, and the engine runs at idle, the transmission oil pump is in short supply, the lubrication condition deteriorates, and in the multi-disc clutch inside the transmission, although the power is cut off, the passive piece is driven at high speed by the wheel. The operation may easily cause resonance and slippage, resulting in undesirable consequences. When the long slope is actually required to slide, the shift lever can be kept in the D block, but the engine can not be turned off.

Myth 3: Starting the engine outside the range of P or N

Some drivers start the engine in gears other than P or N. Although the engine cannot run (because the interlocking mechanism can only be started in P and N gears), it may burn out the transmission's neutral start switch. Because the automatic transmission is equipped with a neutral start switch. The transmission can only be started in the P or N range to prevent the car from starting immediately when the other range is mistakenly started. Therefore, make sure that the shift lever is in P or N before starting the engine.

Myth 4: The cart starts the engine

A vehicle equipped with an automatic transmission and a three-way catalytic converter cannot start because the battery is short of power, but it is very wrong to start using a person pushing or other vehicle dragging method. Because, using the above method can not transmit power to the engine, but will damage the three-way catalytic converter.

Myth 5: Increase the throttle can be changed to high gear

Some drivers think that as long as the D block starts, you can increase the throttle to shift to high speed. Because the shift operation should be "advanced early-advanced throttle, step on the throttle down ahead of schedule." That is, after the start of D block, keep the throttle opening 5%, accelerate to 40km / h, fast loose throttle, can be increased to a gear, and then accelerated to 75km / h, loose throttle can increase a gear. When driving down, press the driving speed and press the throttle slightly to return to the low gear. However, it must be noted that the throttle must not be stepped on. Otherwise, the low gear will be forcibly engaged and the transmission may be damaged.
