These instructions apply to the Suzuki Swift Mk3 (AZG/AZH) 2010-2017.
For other models, please choose your vehicle here.
If the Suzuki Swift (2010–2017) will not crank and the lights are dim, a flat 12-volt battery is the usual cause. The battery sits in the engine bay, and with a set of jump leads and a donor car you can start the Swift in a few minutes. Connect the leads in the right order to avoid sparks and electrical damage.
Before You Start
- Use jump leads rated for the engine size and check them for damage.
- Park the donor car close but not touching, switch both engines off and apply both handbrakes.
- Only jump-start a battery of the same 12V rating — never a frozen or leaking battery.
How to Jump-Start the Swift
- Connect one end of the red positive lead to the (+) terminal of the flat battery in the Swift.
- Connect the other end of the red lead to the (+) terminal of the donor battery.
- Connect one end of the black negative lead to the (–) terminal of the donor battery.
- Connect the other end of the black lead to a solid, unpainted metal earth point on the Swift’s engine — not to the flat battery’s negative terminal, to keep sparks away from battery gases.
- Start the donor car and let it run for a minute, then start the Swift.
- With the Swift running, remove the leads in the exact reverse order and keep them clear of moving parts.
- Drive or idle the Swift for at least 20–30 minutes to let the battery recharge.
FAQ
Where is the battery on a Suzuki Swift?
In the engine bay. Lift the bonnet and you will find the 12V battery with its positive and negative terminals clearly marked.
The Swift still won’t start after a jump — what now?
If it cranks slowly or dies again, the battery is likely at the end of its life or the alternator is not charging. Have both tested.
Do I need to reset anything after a flat battery?
The clock and radio may need re-setting, and on cars with auto up/down windows the power windows may need re-initializing.
If a dead battery leaves stored fault codes once the car restarts, check them against the OBD-II guides at autodtcs.com.
