When your battery is discharged you 
can use two jumper cables to start your 
vehicle with power from the battery in a 
second vehicle. You can also use the 
same method to help start another 
vehicle. Only use jumper cables with 
fully insulated handles on the terminal 
clamps.

Do not touch high-voltage wiring 
and cables on a running engine. 

Contact with components carrying high 
voltage can be harmful or fatal. Care-
fully observe the following instructions 
to avoid personal injury and/or damage 
to one or both vehicles.

<

1. Check whether the battery of the 

support vehicle has 12 volts and 
approximately the same capacity – 
measured in Ah. This information is 
provided on the battery

2. Stop the engine of the support vehi-

cle

3. Switch off all electrical components 

in both vehicles.

Make absolutely certain that there 
is no contact between the body-

work of the two vehicles, otherwise 
there is a short circuit hazard.

<

Always adhere to this sequence 
when connecting jumper cables; 

failure to observe this procedure can 
lead to sparks at the battery terminals 
and pose an injury hazard.
