To prevent battery discharge
Turn off the headlights and the audio system while the engine is off.
Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic.
Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately 5
minutes to recharge the battery of your vehicle.
Maintain the engine speed of the second vehicle and turn
the engine switch to the “ON” position, then start the vehi-
cle’s engine.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order from which they were con-
nected.
Once the engine starts, have the vehicle inspected at any autho-
rized Toyota dealer or repairer, or another duly qualified and
equipped professional, as soon as possible.
