ikeja 29 Posted January 16 Share Posted January 16 How do you jump start another car? Looking under the bonnet it all looks very complicated and I cannot see a clear positive and negative Battery terminal. Quote Link to post Share on other sites
scudney 308 Posted January 16 Share Posted January 16 Be very careful what you do especially if its a hybrid(apparently you shouldn't jump start it the traditional way)🤔 Quote Link to post Share on other sites

Herbie 1,834 Posted January 16 Share Posted January 16 NEVER use a hybrid to jump start another car! You may be lucky but you may find it a very expensive thing to have done. Normal advice is to have the engine of the donor car running because the recipient car draws from the donor alternator. That's not a problem because alternators can provide more than 300A to crank the engine. Our hybrids do not have alternators. Instead, they keep the 12V Battery charged by means of a DC/DC converter - and that device is not capable of supplying anywhere near 300A. As I said, you may be lucky but you may also hear a loud bang and lots of magic smoke come pouring out from your DC/DC converter. EDIT: You should be alright if the other car is a hybrid because they only take 20A or less to get the hybrid system into READY mode - but I can't be held responsible if it also fries the converter. 3 Quote Link to post Share on other sites

ikeja 29 Posted January 17 Author Share Posted January 17 Thanks for all the advice, which I will take onboard. I had thought that it was not a good idea to use a hybrid as the donor, thus I will not be doing so. Guess the best thing is to purchase a jump starter pack but still not too sure about how to connect it. Quote Link to post Share on other sites

Easiest way is to use the charging point in the engine bay, otherwise you have to remove trim in the boot to get to the Battery. 1 Quote Link to post Share on other sites
ikeja 29 Posted January 17 Author Share Posted January 17 Thanks Colin, where is the charging point in the engine bay? 1 Quote Link to post Share on other sites

There is a permanent 12v connection in the fuse box, under a cover, and you then use the engine/body for the -ve connection. 3 Quote Link to post Share on other sites

Barry, it looks like you may not have a copy of the owners manual, take a look at pages 631-635 of the attached which will give you additional info to Colin's excellent reply above. is300h.pdf 2 Quote Link to post Share on other sites
