The correct way to use an exhaust brake is as follows: 1. Automatic shutdown: When the vehicle is in motion and the driver presses the accelerator pedal or clutch pedal, the exhaust brake will automatically shut off. 2. Avoid usage: It is best not to use the exhaust brake when driving in rainy weather or on slippery roads, as it may cause the vehicle to skid or even overturn. Precautions for using the exhaust brake are as follows: 1. The exhaust brake is an auxiliary brake and cannot replace the service brake for emergency braking, nor can it be used for parking braking. However, the exhaust brake can be used simultaneously with the service brake. 2. When using the exhaust brake, the accelerator pedal should be at zero position, and the fuel injector stops injecting fuel. If the accelerator pedal or clutch pedal is pressed, the exhaust brake will automatically shut off, preventing the engine from stalling when stopping and ensuring the exhaust brake operates during fuel injection. 3. It is advisable not to use the exhaust brake on icy or slippery roads, as there is a risk of the vehicle's drive wheels skidding or sliding. 4. The braking power of the engine exhaust brake depends on the engine speed (the higher the engine speed, the better the braking effect). To ensure optimal braking performance when using the exhaust brake on long downhill slopes, select an appropriate gear (the transmission should not be in neutral) to keep the engine speed between 1600-2400 rpm.

If the fog is not heavy and it's not too cold outside, you can slightly open both side windows to allow air convection inside the car.
