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 start the
engine of your vehicle.
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at your Toyota
dealer as soon as possible.
■
Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■
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 running
at a low speed for an extended period, such as in heavy traffic.
■
When the battery is removed or discharged
●
The moon roof must be initialized. (

P. 143)
●
Flex-fuel vehicles: The information recorded in the computer will be cleared,
which may cause the engine to run roughly and reduce driving performance
for a while when the engine is first started. In this case, wait until the engine
runs normally.
If the vehicle is running on E85, the engine may stall.
In this case, restart the engine, repeatedly if necessary.
●
Vehicles with alarm: Make sure that the key is not inside the vehicle when
recharging or replacing the battery. The key may be locked in the vehicle if
the alarm is activated. (

■
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.)
