Connect the jumper cable to ground on your vehicle as shown in the
illustration.
4 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.

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

ized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■Starting the engine when the bat-
tery is discharged

When trouble arises
■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.
■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
●In some cases, it may not be possible
to unlock the doors using the smart
entry & start 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 mal-
function.
●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.
WA R N I N G
■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 + 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.

3627-2. Steps to take in an emergency
1Stop the vehicle in a safe place
and turn off the air conditioning
system, and then stop the
engine.
2 If you see steam: Carefully lift
the hood after the steam sub-
sides.
If you do not see steam: Care-
fully lift the hood.
3 After the engine has cooled
down sufficiently, inspect the
WA R N I N G
●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.
■To prevent damage to the vehicle
Do not pull- or push-start the vehicle
as the three-way catalytic converter
may overheat and become a fire haz- ard.
NOTICE
■When handling jumper cables
Be careful that the jumper cables do
not become tangled in the cooling fans or any of the belts when connect-
ing or disconnecting them.
■When closing the doors
While pushing the door glass towards
the inside of the vehicle, slowly close the door.
Because the side window open/close
function linked to door operation will not operate, the window may interfere
with the vehicle body, possibly
scratching both the vehicle body and window, or even shattering the win-
dow.
If your vehicle overheats
The following may indicate that
your vehicle is overheating.
 The engine coolant tempera-
ture gauge ( P.88) is in the
red zone or a loss of engine
power is experienced. (For
example, the vehicle speed
does not increase.)
 “High Coolant Temperature
Check Owner's Manual” is
shown on the multi-information
display.
 Steam comes out from under
the hood.
