can you jump start new cars

Yes, you can jump‑start many new cars, but only if you do it by the book—modern electronics are as fussy as a barista at 6am.

Use a quality jump pack or another car, connect positive to positive and negative to a solid engine/earth point, and follow the owner’s manual for any designated terminals.

Let the donor idle a minute before cranking, and remove the leads in reverse order to avoid voltage spikes.

Hybrids and EVs are different: you may jump the 12V system to “wake” them, but never touch the high‑voltage battery, and don’t use an EV as a donor unless the manual explicitly allows it.

If the dash lights look like a Christmas tree afterwards, get the battery tested and consider a smart charger rather than another round of cable calisthenics.
