jump start cables, first the negative (black)
cable from both vehicles and then the positive
(red) cable from both vehicles.
Allow the recipient engine to run until the
discharged battery is sufficiently recharged (15
to 20 minutes) to start the engine without
assistance. Set the engine to OFF and restart
the engine. Take the vehicle on a long run to
fully charge the battery.
Contact your Aston Martin Dealer to have the
battery checked or replaced.
Recharge time will depend on the initial 'state of
health' of discharged battery.
If this vehicle will not start consult your
Aston Martin Dealer.
