Can the Jetta NF car battery start the engine without electricity? What to do?

If not, the car battery has no power and cannot start the engine, you can use the jumper cable to connect the battery of another car to start the engine of the car. Check the electrolyte level of the car battery before starting the engine with a jumper cable.

Jumper cables must comply with DIN 72553 (consult manufacturer's documentation) and have a minimum cross-sectional area of 25 mm2 (for petrol engines) and 35 mm2 (for diesel engines).

1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery connection line must buy the right brand, the quality is the best, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it.

2. Emergency power supply: This is a new type of power bank like a thing, there are two kinds of lead-acid and polymer lithium battery, which can help the vehicle with a loss of power to start, and can also have lighting, charging mobile phones and multi-functional supplies used with an inflatable pump to inflate the car. And it is generally portable, very lightweight, if you have it, you don't have to ask others for help.

Be sure to charge it in time after use and keep it full of power to deal with emergencies.

3. Positive, first connect the positive: first turn off all the electrical equipment on the car, make the key in the OFF position, open the cabin cover to find the battery, there are positive and negative poles written on the battery, generally the red "+" sign is the positive pole, and there are generally two wires, at this time, take out the red one, open the battery cover, pinch the clamp on the head to clamp firmly the positive pole of the battery of the electric car, and the clamp at the other end to clamp the positive pole of the battery of the rescue vehicle. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.

4. Negative connection, negative connection: After the red positive electrode is connected, take out another wire, first clamp the negative pole of the tram battery, the negative electrode is generally black "—" number, and then pinch the other end of the clip, from beginning to end the clip do not touch other places, to clamp the negative pole of the rescue vehicle battery, when the connection will pop out of the electric spark, please don't be afraid, this also shows that you are right. The reason why the negative electrode is not connected first is because the whole vehicle is basically a negative electrode (that is, commonly known as "tie iron"), if the negative electrode is connected first, when connecting the positive electrode, the clip will cause a short circuit and burn the parts on the car when it touches any conductive place in the body.

5. After starting the vehicle, first remove the negative, and then dismantle the positive: after the battery is connected, the rescue vehicle will first ignite and charge the battery, and then the no tram enters the vehicle to open the key, at this time the instrument light will be lit smoothly, and then try to ignite (not more than 5 seconds), if it fails to start smoothly, step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then the tram is ignited again, if the starter is no problem, the car has oil in the case of general can be started smoothly, after the non-electric vehicle starts, Remove the negative clamp first, then remove the positive clamp, for the same reason as why the negative pole is followed by the fourth one.

The positive and negative poles of the battery must not be reversed, and the order of assembly and disassembly should be strictly in accordance with the order of first connecting the positive and then the negative, and the first dismantling and then the positive.

If an invalid car key is used or there is a fault in the system, the engine cannot be started.

The risk of serious injury is reduced when the engine is running or when the engine is started.

Never start the engine in poorly ventilated or enclosed spaces! Because the engine exhaust contains colorless and odorless carbon monoxide toxic gas, it can cause coma and even suffocation.

Don't leave your car unattended when the engine is running! The car may suddenly move on its own or other unexpected circumstances may occur, damaging the car or injuring people.

Do not use the starting aid to start the engine! Due to the possibility of starting aids, the engine may suddenly run at high speed and damage the engine.

1. Check the status of the battery.

In most cases, the difficulty of starting the car in winter is caused by the loss of battery power or the expiration of the battery life. When the battery is low, the speed is weak when starting the car, and only the clicking sound is heard, and the clicking sound will gradually become a clicking sound when the ignition is lit again. Do not ignite continuously to avoid the battery running out.

2. Change the appropriate engine oil.

In winter, as the temperature drops, the viscosity of the oil increases, making it difficult for the oil to flow, which increases the resistance of the engine. If it is difficult to start, check whether the oil label is incorrect.

3. Replace the spark plug in time.

After a few years of use, spark plugs are prone to cause problems such as carbon deposition, leakage, excessive clearance, and ablation, which will cause difficulties in car ignition, cold start, and even hot engine start, and often need to be ignited multiple times. Therefore, when driving to a certain number of kilometers or feeling that the vehicle is difficult to start, weak, shaking, increasing fuel consumption, or inexplicably stalling, please check the spark plug status and replace it in time.
