Where is the auto start/stop switch and what is the symbol?

Car automatic start-stop function button symbol is a capital letter A plus a circle, usually on the left side of the dashboard;

1, the engine's automatic start-stop function is in the process of the vehicle driving a temporary stop (such as a red light), the automatic shutdown, when the need to continue to move forward, the system automatically restart the engine of a set of systems;

2, driving as long as directly step on the brake pedal, the vehicle comes to a complete stop for about two seconds, the engine will automatically shut down, has been stepping on the brake pedal, the engine will remain off;

3, as long as you release the brake, or turn the steering wheel, the engine will be immediately automatic ignition, immediately you can step on the gas pedal to start, the whole process is in the state of D gear.

The need to close the automatic start-stop situation:

1, if the vehicle driving to the more hiking ramp, try not to open the automatic start-stop, because the automatic start-stop time is very short, but the engine start-stop on the ramp may cause the vehicle braking assistance is insufficient.

2, in the southern weather hot air conditioning running at full power, it is best to close the automatic start-stop function off, because the air conditioning needs to be relatively large power consumption, and engine shutdown in the case of the body may not be enough to drive the air-conditioning power operation, will make the car passengers feel uncomfortable.

3, the vehicle in the wading driving, it is best to turn off the start-stop system, this is to prevent the need to stop in driving, the engine stalled, when the exhaust pressure suddenly reduced. Water can easily flow backward from the exhaust pipe into the engine, resulting in the engine can not start.

4, if you meet serious traffic, it is also recommended to turn off the automatic start-stop, because at this time the engine stops working longer, the temperature of the combustion chamber is lowered, and the incomplete combustion of hydrocarbons and paraffin waxes will form carbon deposits adhering to the inner wall of the cylinder. Carbon deposits will make fuel consumption higher, power weaker, this is designed to reduce fuel consumption of the automatic start-stop function, in turn, increased fuel consumption.
