CAUTION
When making the connections,
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
9. Charge the discharged battery with the
jumper cables connected for approxi-
mately 5 minutes. At this time, run the
engine in the vehicle with the booster
battery at about 2000 rpm with the ac-
celerator pedal lightly depressed.
10. Start the hybrid system. Make sure the
"READY" light is on. If the hybrid bat-
tery warning light comes on in the mul-
ti−information display, the hybrid battery
is also discharged. Contact your Toyota
dealer.
11. Carefully disconnect the cables in the
exact reverse order: the negative cable
and then the positive cable.
12. Carefully dispose of the battery cover
cloths—they may now contain sulfuric
acid.
13. If removed, replace all the battery vent
plugs.
If the cause of your 12 volt battery dis-
charging is not apparent (for example,
lights left on), you should have it checked
at your Toyota dealer.

Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your hybrid
system in the normal way.
If the another attempt is not successful,
the battery may be depleted. Have it
checked at your Toyota dealer.
