cle with a 12-volt battery, you can
jump start your vehicle by following
the steps below.
1 Vehicles with an alarm (P. 7 6 ) :
Confirm that the electronic key
(vehicles with a smart entry &
start system) or key (vehicles
without a smart entry & start
system) is being carried.

moving parts as shown in the illustration
5 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.
6 Vehicles with a smart entry &
start system: Open and close
any of the doors of your vehicle
with the engine switch OFF.
7 Maintain the engine speed of
the second vehicle and start the
engine of your vehicle by turning
the engine switch to ON.
8 Once the vehicle’s engine has
started, remove the jumper
cables in the exact reverse
order from which they were con-
nected.
9 1ZR-FAE engine: Reinstall the
engine cover.
9 M15A-FKS engine: Reinstall the
positive (+) battery terminal
cover.
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 off.
●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.547)
■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)
●Vehicles with entry function: In some
cases, it may not be possible to unlock the doors using the smart entry
& start system when the battery is dis-
charged. 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 mal- function.

8-2. Steps to take in an emergency
When trouble arises
●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 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 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.

■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.
