Emergency situations
9.Connect the other end of the second
jumper cable to the chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections.
WARNING
Do not connect the jumper cable to the
negative (-) jumper terminal of the
discharged battery. A spark could
cause the battery to explode and lead
to a personal injury or vehicle damage.
10.Start the engine of the assisting vehicle
and let it run at about 2,000 RPM for a
few minutes. Then start your vehicle.
11.Keep your vehicle operating for at least
30 minutes at idle or driving to make
sure your battery receives enough
charge to be able to start on its own
after the vehicle is shut off. A
completely discharged battery may
require as long as 60 minutes runtime
to fully recharge it. If the vehicle has run
for less, the vehicle may not restart.
If your vehicle does not start after a few
attempts, it probably requires service. In
this event please seek qualified
assistance. We recommend that your
vehicle be inspected by a HYUNDAI
authorised repairer.
