7-2. Steps to take in an emergency
to the mode it was in before the bat-
tery was discharged. Before discon- necting 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.
■When replacing the battery
●Use a battery that conforms to Euro-
pean regulations.
●Use a battery that the case size is
same as the previous one, 20 hour rate capacity (20HR) is equivalent or greater, and performance rating
(CCA) is equivalent or greater. Check the label on top of the battery for the battery size and specifications (ex.
LN2, 60Ah, 345A). • 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.
WARNING
■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.
●Always wash your hands after han-dling the battery support, terminals,
and other battery-related parts.
●Do not allow children near the bat-
tery.
