Starting the engine when the battery is discharged (vehicles with a
Multidrive)
The engine cannot be started by push-starting.
Avoiding a discharged battery
Turn off the headlights and the audio system while the engine is turned
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, etc.
When the vehicle battery is removed or discharged
Any data stored in the computer will be erased. When the vehicle battery
is discharged, have the vehicle checked at any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
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. (P. 120)
Reminders when the vehicle battery is discharged (vehicles with smart
entry & start system)

system just after the vehicle battery has been discharged, it may fail. If
the doors cannot be unlocked, unlock the doors using a wireless remote
controller or a mechanical key.
The first engine start after the battery has been discharged may fail.
However, the engine should start after the second attempt, so it is not a
malfunction.

When trouble arises

The status of the “ENGINE START STOP” switch remains stored in the
vehicle memory. When the vehicle battery is discharged, the vehicle
returns to the status before the battery was discharged after disconnect-
ing and reconnecting the battery. When the battery needs to be discon-
nected, turn the “ENGINE START STOP” switch off before disconnecting
the battery. If the “ENGINE START STOP” switch status before the bat-
tery discharge is unknown, pay due attention to the vehicle when the bat-
tery is reconnected.
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.)
CAUTION
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
Do not allow the jumper cables to come into contact with the “+” and “-” ter-
minals.
Do not allow open flame or use matches, cigarette lighters or smoke near
the battery.
Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery.
When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
Do not lean over the battery.
