3287-2. Steps to take in an emergency
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the batter y of your vehicle.
Maintain the engine speed of t he second vehicle and start the
engine of your vehicle.
Once the vehicle’s engine has star ted, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the v ehicle inspected at your Toyota
dealer as soon as possible.
■ Starting the engine when the batt ery is discharged (vehicles with an
automatic transmission)
The engine cannot be started by push-starting.
■ To prevent battery discharge
●Turn off the headlights and the audio system while the engine is not running.
● Turn off any unnecessary electrical components when the vehicle is running
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.)
