8-2. Steps to take in an emergency
When trouble arises
If you have a set of jumper (or  
booster) cables and a second vehi-
cle with a 12-volt battery, you can 
jump start your vehicle by following 
the steps below. 
1 Vehicles with an alarm (P. 8 1 ) :   
Confirm that the key is being 
carried.
When connecting the jumper (or  booster) cables, depending on the situ- 
ation, the alarm may activate and doors  
locked. ( P. 8 2 )
2Open the hood. (P.470) 
3 Connect a positive jumper cable clamp to   on your vehicle and con- 
nect the clamp on the other end of the positive cable to   on the sec-
ond vehicle. Then, connect a negativ e cable clamp to   on the second  
vehicle and connect the clamp at the other end of the negative cable to  
.

minutes to recharge the battery  
of your vehicle. 
5 Vehicles with a smart entry &  
start system: Open and close 
any of the doors 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 con-
nected. 
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 stopped. 
(Vehicles with Stop & Start system:  except when the engine is stopped by  
the Stop & Start system.)
●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.587)
■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: In some cases, it may not be 
possible to unlock the doors using the  smart entry & star t system when the  
battery is discharged. Use the wire-
less remote control or the mechanical  key to lock or unlock the doors.
●Vehicles with a smart entry & start system: 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.
●Vehicles with a smart entry & start 
system: 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 dis-
connecting 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.

8-2. Steps to take in an emergency
When trouble arises
●Vehicles with Stop & Start system:  
After the battery terminals have been  disconnected and reconnected, or  
after the battery has been replaced, 
the Stop & Start system may not auto- matically stop the engine for approxi- 
mately 5 to 60 minutes.
■When replacing the battery
●Use a battery that conforms to Euro-
pean regulations.
●Vehicles with Stop & Start system: 
Use a genuine battery specifically 
designed for use with the Stop & Start  system or a battery with equivalent  
specifications to a genuine battery. If 
an unsupported battery is used, Stop  & Start system functions may be  
restricted to protect the battery. Also, 
battery performance may decrease  and the engine may not be able to  
restart. Contact any authorized Toyota 
retailer or Toyota authorized repairer,  or any reliable repairer for details.
●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. 

5608-2. 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
●Always wash your hands after han- 
dling the battery support, terminals, 
and other battery-related parts.
●Do not allow children near the bat-
tery.
■When replacing the battery
●When the vent plug and indicator 
are close to the hold down clamp,  the battery fluid (sulfuric acid) may  
leak.
●For information re garding battery  
replacement, contact any author-
ized Toyota retailer or Toyota  authorized repairer, or any reliable  
repairer.
NOTICE
■When handling jumper cables 
When connecting the jumper cables,  
ensure that they do not become 
entangled in the cooling fans or 
engine drive belt.
If  your vehicle overheats
The following may indicate that  
your vehicle is overheating.
 The engine coolant tempera- 
ture gauge ( P.89, 93) is in  
the red zone or a loss of 
engine power is experienced. 
(For example, the vehicle 
speed does not increase.) 
 “Engine Coolant Temp High  
Stop in a Safe Place See 
Owner’s Manual” is shown on 
the multi-information display. 
 Steam comes out from under  
the hood.
