Starting with jumper
cables
If necessary, the engine can be started by con­

If the engine should fail to start because o f a dis­
charged or weak battery, the battery can be con­

another vehicle, us ing a
pair of jumper cables to start the engine .
Jumper cables
Use only jumper cables of sufficiently large cros s
section
to carry the starter current safe ly. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated term inal
clamps which are distinctly marked:
plus(+) cable in most cases co lored red
minus (-) cable
in most cases colored black .

- Do not try to jump start any vehicle with a
low acid level in the battery.
- The voltage of the booster battery must al ­
so have a 12-volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of batteries of different voltage or substantial­
ly different" Ah" rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery . Gas trapped
in the ice may cause an explosion .
- Never charge or use a battery that has been
frozen . The battery case may have be weak­
ened ,
- Use of batter ies of different voltage or sub­
stantially different capacity (Ah) rating may
cause an exp losion and injury. Th e capacity
(Ah) of the booste r battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed a ll
WARNINGS
q page 218 .
(D Note
-Applying a h igher voltage booster battery
w ill cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- Th ere must be no ele ct rical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) termina ls are connected.
(D Tips
