7-2. Steps to take in an emergency

Connect the jumper cables according to the following procedure:

Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.
Connect  the  clamp  at  the  other  end  of  the  negative  cable  to  a
solid, stationary, unpainted metallic point away from the battery
and any moving parts, as shown in the illustration.

Start the engine of the second vehicle. Increase the engine speed
slightly  and  maintain  at  that  level  for  approximately  5  minutes  to
recharge the battery of your vehicle.

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 electrical 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 stored in the ECU is cleared. When the battery is depleted, have
the vehicle inspected at your Toyota dealer.

Some systems may require initialization. (

P. 499)

When removing the battery terminals
When the battery terminals are removed, the information stored in the ECU is
cleared. Before removing the battery terminals, contact your Toyota dealer.

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.)

When recharging or replacing the battery

In some cases, it may not be possible to unlock the doors using the smart
key 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 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 battery, turn the engine switch off. 
If you are unsure what mode the engine switch was in before the battery dis-
charged, 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 (LN3), 20 hour
rate capacity (20HR) is equivalent (70Ah) or greater, and performance rating
(CCA) is equivalent (603A) 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 battery may discharge and the engine
may not be able to start.

For details, consult your Toyota dealer.

WARNING

When removing the battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts  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 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 other end of the jumper cable connected to the “+” termi-
nal 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 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.

NOTICE

When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fan or engine drive belt.
