These instructions apply to the Hyundai i10 Mk2 (IA) 2014-2019.

A flat 12 V battery is the most common reason a Hyundai i10 (IA, 2014–2019) won’t crank. With a set of jumper leads and a healthy 12 V donor car you can get going in a few minutes — as long as you connect the leads in the right order.
Before You Start
- Use only a 12 V donor source — a higher voltage will damage the i10’s electrics.
- Never jump a battery that is frozen or low on electrolyte — it can crack or burst.
- Keep sparks and flames away; the battery gives off hydrogen gas.
- Park the cars close but not touching, both ignitions off, and switch off all electrical loads.
How to Connect the Leads
- Connect one end of the red (+) lead to the positive (+) terminal of the flat battery.
- Connect the other end of the red lead to the positive (+) terminal of the donor battery.
- Connect one end of the black (−) lead to the negative (−) terminal of the donor battery.
- Connect the other end of the black lead to the negative (−) terminal of the flat battery. Keep the leads clear of any moving engine parts, and clip them to the terminals only.
- Start the donor car, hold it at about 2,000 rpm, then start the i10.
Once the i10 is running, remove the leads in the exact reverse order (4 → 3 → 2 → 1). Never touch the donor’s negative lead to the flat battery’s positive terminal — that can overheat and split the battery.
Don’t Push- or Tow-Start It
A manual i10 should not be push- or tow-started — it can damage the emission-control system — and an automatic can’t be started that way at all. Use jumper leads instead.
If Your i10 Has ISG (Stop/Start)
After the battery has been flattened, jumped or reconnected, the Idle Stop & Go system stays inactive until the battery sensor recalibrates — roughly 4 hours with the ignition off. That’s normal; see our i10 stop/start guide.
Frequently Asked Questions
Which terminal do I connect last?
The negative (−) terminal of the flat battery, after both positives and the donor negative are on. Remove that clip first when you disconnect.
My i10 started, then died again — why?
The battery isn’t holding charge, or the alternator isn’t charging. Drive for a while to recharge; if it goes flat again, have the battery and charging system tested.
Can I use a jump pack instead of another car?
Yes — any 12 V lithium jump pack works. Follow the same order: pack positive to battery positive, pack negative to battery negative.
Why won’t stop/start work after a jump-start?
The ISG battery sensor needs to relearn the battery’s state of charge — leave the car off for a few hours and it returns on its own.
If a warning light stays on after the jump, look the code up on autodtcs.com. To safely disconnect the battery, see our i10 battery guide.
