●If recharging with the battery installed
on the vehicle, be sure to disconnect the ground cable.
●Make sure the charger is off when connecting and disconnecting the
charger cables to the battery.

Coolant is neither plain water nor
straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication,
corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.

Keep the plate in a safe place
such as your wallet, not in the
vehicle.
NOTICE
■When an electronic key is lost
(vehicles with a smart entry &
start system)
If the electronic ke y remains lost, the
risk of vehicle thef t increases signifi-
cantly. Visit any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer immediately
with all remaining electronic keys that were provided with your vehicle.
If the electronic key
does not operate prop-
erly (vehicles with a
smar t entr y & star t sys-
tem)
If communication between the
electronic key and vehicle is
interrupted ( P.138) or the
electronic key cannot be used
because the battery is
depleted, the smart entry &
start system and wireless
remote control cannot be used.
In such cases, the doors can
be opened and the engine can
be started by following the pro-
cedure below.
NOTICE
■In case of a smart entry & start
system malfunction or other key-related problems
Take your vehicle with all the elec-
tronic keys provided with your vehicle to any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.

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.
