When trouble arises
■Changing engine switch modes
Release the brake pedal (automatic 
transmission) or clutch pedal (man-
ual transmission) and press the 
engine switch in step  3 above.
The engine does not start and 
modes will be cha nged each time 
the switch is pressed. ( P.147)
If you have a set of jumper (or 
booster) cables and a second 
vehicle with a 12-volt battery, 
you can jump start your vehicle 
by following the steps below.
1Confirm that the electronic 
key is being carried.
When connecting the jumper (or 
booster) cables, depending on the 
situation, the alarm may activate 
and doors locked.
2Open the hood. ( P.302)
3 Connect a positive jumper cable clamp to   on your vehicle and 
connect the clamp on the other end of the positive cable to   on  
the second vehicle. Then, connect a negative cable clamp to   
If  the vehicle batter y 
is discharged
The following procedures 
may be used to start the 
engine if the vehicle’s bat-
tery is discharged.
You can also call your Toy-
ota dealer or a qualified 
repair shop.

on the second vehicle and connect the clamp at the other end of 
the negative cable to  .
Positive (+) battery terminal (your vehicle)
Positive (+) battery terminal (second vehicle)
Negative (-) battery term inal (second vehicle)
Connect the jumper cable to ground on your vehicle as shown in 
the illustration.
4 Start the engine of the sec-
ond vehicle. Increase the 
engine speed slightly and 
maintain at that level for 
approximately 5 minutes to 
recharge the battery of your 
vehicle.
5 Open and close any of the 
door 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 bat tery 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 trouble arises
■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.
■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 terminals, contact 
your Toyota dealer.
■Charging the battery
The electricity stor ed in the battery 
will discharge gradu ally 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 ma y 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 battery was dis-
charged. Before disconnecting the 
battery, turn the engine switch off.
If you are unsure what mode the 
engine switch was in before the 
battery discharged, be especially 
careful when reconnecting the 
battery.
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, leading to a fire 
in addition to ele ctrical 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 + and - clamps 
of the jumper cables to come 
into contact with each other.
●Do not smoke, use matches, 
cigarette lighter s 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.

3747-2. Steps to take in an emergency
1Stop the vehicle in a safe 
place and turn off the air con-
ditioning 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: 
Carefully lift the hood.
3 After the engine has cooled 
down sufficiently, inspect the 
WARNING
●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 child ren near the 
battery.
■To prevent damage to the 
vehicle
Do not pull- or push-start the vehi-
cle as the three-way catalytic con-
verter may overheat and become 
a fire hazard.
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 connecting 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 no t operate, the 
window may inte rfere with the 
vehicle body, possibly scratching 
both the vehicle body and win-
dow, or even shattering the win-
d o w.
If  your vehicle over-
heats
The following may indicate 
that your vehicle is over-
heating.
 The engine coolant tem-
perature gauge ( P.88) is 
in the red zone or a loss of 
engine power is experi-
enced. (For example, the 
vehicle speed does not 
increase.)
 “High Coolant Temperature 
Check Owner's Manual” is 
shown on the multi-informa-
tion display.
 Steam comes out from 
under the hood.
