3607-2. Steps to take in an emergency
recharge the battery of your 
vehicle.
5 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 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 electri-
cal 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
●Information stor ed in the ECU is 
cleared. When the battery is 
depleted, have the vehicle 
inspected at you r Toyota dealer.
●Some systems may  require initial-
ization. ( P.395)
■When removing the battery ter-
minals
When the battery terminals are 
removed, the information stored in 
the ECU is cleared. Before remov-
ing the battery term inals, contact 
your Toyota dealer.
■Charging the battery
The electricity stored in the battery 
will discharge grad ually even when 
the vehicle is not in use, due to nat-
ural discharge and the draining 
effects of certain  electrical appli-
ances. If the vehicle is left for a long 
time, the battery  may discharge, 
and the engine may be unable to 
start. (The battery recharges auto-
matically during driving.)
■When recharging or replacing 
the battery
●In some cases, it may not be pos-
sible to unlock the doors using the 
smart key system when the bat-
tery is discharged. Use the wire-
less 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 switch mode is memo-
rized by the vehicle. When the 
battery is reconnected, the system 
will return to the mode it was in 
before the bat tery was dis-
charged. Before disconnecting the 
battery, turn the engine switch off.
If you are unsure what mode the 
engine switch wa s in before the 
battery discharged, be especially 
careful when reconnecting the 
battery.
■When replacing the battery
●Use a battery that conforms to 
European regulations.
●Use a battery that the case size is 
same as the previous one (LN1), 
20 hour rate capacity (20HR) is  
3617-2. Steps to take in an emergency
7
When trouble arises
equivalent (45Ah) or greater, and 
performance rating (CCA) is 
equivalent (307A) or greater.
• If the sizes differ, the battery can- not be properly secured.
• If the 20 hour rate  capacity is low, 
even if the time period where the 
vehicle is not used is a short time, 
the battery may discharge and the 
engine may not be able to start.
●For details, consu lt your Toyota 
dealer.
WARNING
■When removing the battery 
terminals
Always remove the negative (-) 
terminal first. If the positive (+) ter-
minal contacts any metal in the 
surrounding area when the posi-
tive (+) terminal is removed, a 
spark may occur, l eading to a fire 
in addition to electrical shocks 
and death or serious injury.
■Avoiding battery fires or 
explosions
Observe the following precautions 
to prevent accidentally igniting the 
flammable gas that may be emit-
ted from the battery:
●Make sure each jumper cable is 
connected to the correct termi-
nal and that it is not unintention-
ally 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 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 precautions when 
handling the battery:
●When working with the battery, 
always wear safety glasses and 
take care not to allow any bat-
tery 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 bat-
tery-related parts.
●Do not allow children near the 
battery.
NOTICE
■When handling jumper cables
When connecting the jumper 
cables, ensure that they do not 
become entangled in the cooling 
fan or engine drive belt.
