5588-2. Steps to take in an emergency
minutes to recharge the battery
of your vehicle.
5 Vehicles with a smart entry &
start system: Open and close
any of the doors of your vehicle
with the engine switch OFF.
6 Maintain the engine speed of
the second vehicle and start the
engine of your vehicle by turning
the engine switch to ON.
7 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 author-
ized Toyota reta iler or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■Starting the engine when the bat- tery 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 stopped.
(Vehicles with Stop & Start system: except when the engine is stopped by
the Stop & Start system.)
●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.
■When the battery is removed or dis-
charged
●Information stored in the ECU is
cleared. When the battery is depleted,
have the vehicle inspected at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
●Some systems may require initializa-
tion. ( P.587)
■When removing the battery termi- nals
When the battery terminals are
removed, the information stored in the ECU is cleared. Before removing the
battery terminals, contact any author-
ized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Charging the battery
The electricity stored in the battery will
discharge gradually even when the vehi- cle is not in use, due to natural dis-
charge and the draining effects of
certain electrical appliances. If the vehi- cle is left for a long time, the battery may
discharge, and the engine may be una-
ble to start. (The battery recharges auto- matically during driving.)
■When recharging or replacing the
battery
●Vehicles with a smart entry & start
system: In some cases, it may not be
possible to unlock the doors using the smart entry & star t system when the
battery is discharged. Use the wire-
less remote control or the mechanical key to lock or unlock the doors.
●Vehicles with a smart entry & start system: 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 mal-
function.
●Vehicles with a smart entry & start
system: The engine 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 dis-
connecting the battery, turn the engine switch off.
If you are unsure what mode the
engine switch was in before the bat- tery discharged, be especially careful
when reconnecting the battery.

8-2. Steps to take in an emergency
When trouble arises
●Vehicles with Stop & Start system:
After the battery terminals have been disconnected and reconnected, or
after the battery has been replaced,
the Stop & Start system may not auto- matically stop the engine for approxi-
mately 5 to 60 minutes.
■When replacing the battery
●Use a battery that conforms to Euro-
pean regulations.
●Vehicles with Stop & Start system:
Use a genuine battery specifically
designed for use with the Stop & Start system or a battery with equivalent
specifications to a genuine battery. If
an unsupported battery is used, Stop & Start system functions may be
restricted to protect the battery. Also,
battery performance may decrease and the engine may not be able to
restart. Contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer for details.
●Use a battery with the same case size as the previous battery and an equiva-
lent 20 hour rate capacity (20HR) or
greater. • If the sizes differ, the battery cannot
be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the bat-
tery may discharge and the engine may not be able to start.
●For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
WA R N I N G
■When removing the battery ter-
minals
Always remove the negative (-) termi-
nal first. If the positive (+) terminal
contacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading
to a fire in addition to electrical shocks and death or serious injury.
■Avoiding battery fires or explo-sions
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 other end of the
jumper cable connected to the “+”
terminal to come into contact with any other parts or metal surfaces in
the area, such as brackets or
unpainted metal.
●Do not allow the + and - clamps of
the jumper cables to come into con- tact with each other.
●Do not smoke, use matches, ciga-rette 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
precautions when handling the bat- tery:
●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 atten-
tion. Place a wet sponge or cloth over the affected area until medical
attention can be received.
