your vehicle with power from the bat-
tery in a second vehicle. You can also
use the same method to help start
another vehicle. Always 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

your vehicle's electrical system.

in both vehicles
3. Make absolutely certain that there
is no contact between the body-
work of the two vehicles – short cir-
cuit hazard

nect the positive terminal of the

port vehicle's negative battery ter-
minal or a suitable ground on its
