& WARNING
Batteries contain electricity , acid , and gas. Any of these can cause
very serious or fatal injury. Follow the instructions below for safe
handling of your vehicle 's battery.
• Always shield your eyes and avoid leaning over the battery
whenever possible .
• A discharged battery can freeze at temperatures just below
32 °F (0 °C l. Before connecting a jumper cable, you must thaw the
frozen battery completely , otherwise it could explode .
• Do not allow battery a cid to contact eyes or skin . Flush any
contacted area with water immediately .
• Improper use of a booster battery to start a vehicle may cause
an explosion.
• Vehicle batteries generate e xplosive gases . Keep sparks, flame
and lighted cigarettes away from batteries.
• Do not try to jump start any vehicle with a low ac id level in the
battery.
• The voltage of the booster battery must also have a 12-Volt
rating . The capacity (Ahl of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
different voltage or substantially different
" Ah " rating may cause
an explosion 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 weakened.

fl::. WARNING (continued)
• Before you check anything in the engine compartment, always
read and heed all
WARNINGS~ page 299, "Engine compartment".
0 Note
• Applying a higher voltage booster battery will cause expensive
damage to sensitive electronic components, such as control units,
relays, radio, etc .
• There must be no electrical contact between the vehicles as
otherwise current could already start to flow as soon as the positive
( + ) terminals are connected.
[ i) Tips
• The discharged battery must be properly connected to the
vehicle's electrical system. When jump starting or charging the battery , never connect the negative ground cable to the battery
negative post because the battery manager system must be able to
detect the battery's state of charge. Always connect the negative
ground cable to the negative ground post of the battery manager
control unit .•

4. Connect the other end to the negative ground post of the
battery manager control unit located next to the battery.
Starting the engine
-Start the engine of the vehicle with the booster battery.
Run the engine at a moderate speed.
- Start engine with discharged vehicle battery in the usual
manner .
- If the engine fails to start: do not keep the starter
cranking for longer than 10 seconds. Wait for about 30
seconds and then try again.
- With engine running, remove jumper cables from both vehicles in the exact
reverse order.
The battery is vented to the outside to prevent gases from entering
the vehicle interior . Make sure that the jumper clamps are well
connected with their metal ports in full contact with the battery
terminals.
& WARNING
To avoid serious personal injury and damage to the vehicle, heed all warnings and instructions of the jumper cable manufacturer. If
in doubt, call for road service.
• Jumper cables must be long enough so that the vehicles do not
touch.
• When connecting jumper cables, make sure that they cannot
get caught in any moving parts in the engine compartment.
• Before you check anything in the engine compartment, always
read and heed all
WARNINGS ~ page 299, "Engine compartment".
0 Note
Improper hook -up of jumper cables can ruin the generator. •
Always connect POSITIVE(+) to POSITIVE(+), and NEGATIVE(-) to
NEGATIVE( -) ground post of the battery manager control unit.
• Check that all screw plugs on the battery cells are screwed in
firmly. If not, tighten plugs prior to connecting clamp on negative
battery terminal.
• Please note that the procedure for connecting a jumper cable as
described above applies specifically to the case of your vehicle
being jump started. When you are giving a jump start to another
vehicle, do not connect the negative(-) cable to the negative(-)
terminal on the discharged
battery @~ page 365, fig. 297. Instead,
securely connect the negative(-) cable to either a solid metal
component that is firmly bolted to the engine block or to the engine
block itself. If the battery that is being charged does not vent to the
outside, escaping battery gas could ignite and explode! •
Emergency towing with commercial
tow truck
General hints
