3. Attach the remaining jumper cable FIRST to the neg-
ative terminal (black “–” or “N”) of the good battery.
4. Attach the other end of the negative cable to a bare
metal part bolted to the engine block or clamp directly
to the engine block if possible.
IMPORTANT: Always connect positive (+) to positive (+)
and negative (–) to negative (–).
5. Start the engines:
• Start the vehicle that has the good battery first. Let it
run for a few minutes.
• Then start the vehicle that has the discharged
(dead) battery.
If the engine fails to start, do not continue to crank the
starter but contact the nearest Authorized Service
Center.
Remove jumper cables:
WARNING! When disconnecting jumper
cables, make sure they do not get caught in
any moving parts in the engine compartment.
You could be killed or seriously injured.
Reverse the above procedure exactly when removing the
jumper cables. With engine running, disconnect jumper
cables from both vehicles in the exact reverse order
(Steps 4 – 1), making sure to first remove the negative
cable from the vehicle with the discharged battery.
Battery Charging
Except for using small trickle charges (as explained on
Page 222
) to maintain battery condition, you should have
your vehicle's batteries charged by a qualified service
facility.
WARNING! Batteries can kill or injure you
severely. They contain acid, produce poison-
ous and explosive gases, and supply levels of
electric current high enough to cause burns.
A spark or flame near a battery on charge may
cause it to explode with great force.
To help reduce the risk of personal injuries, follow these
guidelines carefully when recharging a battery:
• Before attempting any service in the electrical installa-
tion, disconnect the battery negative cable.
• Allow no sparks or open flame anywhere near the
charging area.
