Is there anything I should know before attempting to boost my girlfriend's car with my IS250?


Basic boosting practice would be:

Turn off IS250.

Connect terminals - POS then NEG to respective battery terminals on IS250, then POS to POS on dead car, and NEG to ground on dead car.

Start IS250.

Attempt to start dead car.

Let both run for a while, then disconnect terminals in reverse order.


The reason I ask if this is alright is because I've heard of other people with newer cars having issues with their electronics after boosting another car. Mine is a 2008, and I'm planning to boost my girlfriend's 2006 Honda Civic DX.

Hoping anyone with experience can chime in before the work day is over! Thanks.

I have actually used my IS 250 AWD to jump start my sister's Solara which had a dead battery. My electronics haven't acted up after the instance; it's more of the fact that I wasn't so happy using a new battery on my IS to jump start the car. I also had to jump start my mom's Camry with my IS too without issues.

 

Man there's nothing that special about doing it. Just connect cables and start the woman car lol... You will be fine. I start mine connect up plugs then connect the dead car and one crank

 

Use the IS to charge the battery on the other car of like 5min the remove cables and start the other car. this will avoid electrical problems from a serge from the other car

 

There is something special about it. The most important point to remember is:

1) Your car (the car with the good battery) should be on before you connect any of the terminals

2) You should never connect both the positive (red) and negative (black) terminals on the same car in a row.

Here's a step by step list of what you should do:

1) Turn your car on (the car with the good battery)

2) Connect the positive, red terminal to the positive terminal of your battery (the car with the good battery)

3) Connect the positive, red terminal to the positive terminal of the other car (the car with the bad battery)

4) Connect the negative, black terminal to the negative terminal of your battery (the car with the good battery)

5) This step is controversial. Some people say that the negative, black terminal should be connected to ground at a location away from the battery of the bad car because this minimizes the chance of a spark-induced explosion.

Most people simply connect the remaining black to the negative terminal of the bad car. Some people connect the remaining black to a good conductor to ground away from the battery.

The probability of exploding batteries is pretty small so I usually just connect the black to the negative terminal.


6) Obviously at this point, the good car should be on (it should have been on from the start before you connected the red to the positive terminal of your car) and the other car should be off.

Wait a couple of minutes to let the battery charge. After about 2-3 minutes of waiting, try to turn the car on.

 

Like DGNY said though, if you let the other car charge for a bit, you should be able to start it with the cables removed.

 

Red--->red
Black--->black

Never mix pos/neg. most jumper cables are color coded so you know exactly where to connect them.

 

your negative cable should always connect last

 

Good tutorial..

People have to make sure what terminal they are connecting to, some cars its hard to tell, I almost started a fire in my last car, the jumper cable started to melt...luckily I yanked it off.

 

technically, you don't connect the negativeclamp to the negative terminal. you should clamp it on a good ground somewhere on the engine bay to prevent you from exploding the battery.

 

My husband has a Lexus H250. I need him to jump my Lexus Gx470. Do we jump it from the front battery. . There is also a charging battery in the back. We just got his car so we want to be cautious.He is sick so I may have to do it alone I know how to jump a battery generally, but his H250 battery looks different than what I am used to.
