The procedure for jump starting is different for every vehicle, and serious damage can be caused if it is done incorrectly. Please consult your vehicle owner’s manual and follow the procedure detailed by the manufacturer.


The following information is for illustration of a typical jump start procedure only. You should not attempt a jump start unless you are confident and have the technical understanding to do so. It is essential that the correct procedure as defined by the vehicle manufacturer’s handbook is always followed.

GS Yuasa accepts no responsibility for any damage caused by following this guide.

A typical vehicle jump start procedure is as follows:


  • Make sure the vehicles are not touching, the ignition in both vehicles is turned off and both vehicles are in neutral or park.


  • The most common procedure is to firstly connect the red positive cable to the positive terminal on the non-start vehicle battery.


  • Then connect the opposite end of this cable to the positive terminal on the jump vehicle’s battery.


  • Now connect the black negative cable to the negative terminal on the jump vehicle’s battery.



  • Finally connect the other end to a suitable earth point on the non-start vehicle, away from the battery and clear of fuel lines and brake pipes. A suitable point is the engine block.


  • Ensure all connections are tight and away from moving or rotating components.


  • Start the jump vehicles engine and allow it to run for one minute.


  • Start the engine of the non-start vehicle and allow it to run for at least one minute before switching off the jump vehicles engine.


  • Remove the cables in the opposite order keeping them well away from any moving or rotating components on the vehicle.


  • If any injury occurs during this procedure seek medical advice as appropriate to the injury.
