Steps
Confirm a flat battery (not alternator)
Dashboard lights dim, no crank, dead clock — flat battery. If the car was driven recently and died, suspect the alternator and call a flatbed.
Connect red (+) to dead car positive
Identify the positive terminal (red cap or '+' sign) on the dead battery.
Connect red (+) to good car positive
Other end of the red cable on the good car's positive terminal.
Connect black (–) to good car negative
Black to the good car's negative terminal.
Connect black (–) to bare metal on dead car
Not the dead battery — clamp on a bare metal bolt on the engine block. This prevents a spark over hydrogen gas.
Start good car, then dead car
Let the good car idle 2–3 minutes, then start the dead car. Once running, remove cables in reverse order.
FAQ
Can I jump-start an EV?
Only the 12V auxiliary battery — never the high-voltage pack. Procedure is the same as a petrol car for the 12V; the EV then 'boots' and the HV pack handles itself.
No jumper cables — what do I do in Thailand?
Call +66 92 910 6168 or LINE @859zfnis. A roadside unit with a lithium jump-pack arrives in 20–40 minutes in Bangkok and major tourist cities.
