190 Starting and driving
WARNING
Do not let the other end touch anything
until the next step. The other end of the
negative cable does not go to the dead
battery. It goes to a major metal part with
a good ground on the engine of the vehi-
cle with the discharged battery.
9 Attach the cable at least 18 inches
(45 cm) away from the discharged bat-
tery, but not near engine parts that
move. To avoid an arc which could deto-
nate the hydrogen gas around the bat-
tery, the final connection must be at least
18" from the battery.
10 Start the vehicle with the good battery
and run the engine for a while.
11 Try to start the vehicle with the dis-
charged battery. If it does not start after
a few tries, it probably needs service.
12 Remove the cables in reverse order to
prevent electrical shorting. Take care
that they do not touch each other or any
other metal.
Charging the battery/Jump
starting
To avoid damaging the car's electrical
system and electronics, the following rules
must be followed when charging the battery
or jump starting the car.
• If the charger 1 or starter unit 1 can be

selected.
• Follow the manufacturer's instructions
supplied with the charger or starter unit.
• Nothing that is plugged into an electrical
outlet should be connected to the car
during charging or jump starting.
• The charger or starter unit must under no
conditions produce a voltage greater
than:
• 16V continuous
• 18V for 60 min.
• If you are unsure about the charge rating
of the unit, disconnect the battery clamp
from the positive terminal before connect-
ing the unit to the battery.
