Push or bump starting only works on manual cars. You push the car, put it in gear and release the clutch to turn the engine. The RAC doesn't recommend it. Use jump leads or a portable battery pack instead. Automatic cars can't be push started, and many modern cars aren't suited to it.
What the RAC says
The RAC states that it does not recommend push starting or bump starting a vehicle. It advises using jump leads or a portable battery pack instead.
How bump starting works
On a manual car, the moving wheels can turn the engine through the gearbox when the clutch is released in gear. The RAC describes this as needing a manual car, two people to push, and a speed of about 10 to 15 mph. That's why it can't work on an automatic.
Why it's risky
- the RAC does not recommend it
- it doesn't fix the battery, which will still need recharging or replacing
Safer options
- Jump leads and a donor car. Follow the RAC or AA steps.
- A portable booster pack. The RAC suggests keeping one in the car.
- A mobile jump start. Jump Start Car does these from £70. Call 0333 567 1785.
