Use only jumper cables of suffic iently large
cross
section
to carry the starter current safely.
Refer
to the manufacturer's
specifications.

away from batteries.
-
Do not try to jump start any vehicle with a
low acid
level
in the battery
.
-
The voltage of the booster battery must also
have a 12-volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged
battery.
Use of
batter ies of different voltage or substantial-
ly different "Ah" rating
may
cause an exp lo-
sion and personal injury
.
