When trouble arises

Starting the engine when the battery is discharged (vehicles with a
Multidrive)
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 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.)
Precautions when the battery is discharged (vehicles with a smart
entry & start system)
In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the battery is discharged. Use the wireless
remote control or the mechanical key to lock or unlock the doors.
The engine may not start on the first attempt after the battery has
recharged but will start normally after the second attempt. This is not a
malfunction.
The “ENGINE START STOP” switch mode is memorized by the vehicle.
When the battery is reconnected, the system will return to the mode it
was in before the battery was discharged. Before disconnecting the bat-
tery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
before the battery discharged, be especially careful when reconnecting
the battery.

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 each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
Do not smoke, use matches, cigarette lighters or allow open flame 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.
In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
Do not allow children near the battery.
To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
(gasoline-powered vehicles) or catalytic converter (diesel-powered vehicles)
may overheat and become a fire hazard.

To prevent 12-volt battery discharge
Turn off the headlights and the audio system while the hybrid system 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.
Precautions when the 12-volt battery is discharged
In some cases, it may not be possible to unlock the doors using the smart
entry & start system immediately after the 12-volt battery has been dis-
connected and reconnected. Use the wireless remote control or the
mechanical key to lock or unlock the doors.
Open and close any of the doors of your vehicle with the
engine switch (vehicles without an electronic key) or
“POWER” switch (vehicles with an electronic key) off.
Maintain the engine speed of the second vehicle and start
the hybrid system of your vehicle by turning the engine
switch (vehicles without an electronic key) to “ON” position
or “POWER” switch (vehicles with an electronic key) to ON
mode.
Make sure the “READY” indicator comes on. If the indicator
does not come on, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped profes-
sional.
Once the hybrid system has started, remove the jumper
cables in the exact reverse order from which they were con-
nected.
Once the hybrid system starts, have the vehicle inspected at any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional as soon as possible.
