When trouble arises
Connect the jumper cables according to the following procedure:
2.5 L 4-cylinder (A25A-FKS) engine
3.5 L V6 (2GR-FKS) engineConnect a positive jumper cable clamp to the positive (+) batte ry
terminal on your vehicle.
Connect  the  clamp  on  the  other  end  of  the  positive  cable  to  the
positive (+) battery termi nal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery term i-
nal on the s econd vehicle.
Connect  the  clamp  at  the  other  e nd  of  the  negative  cable  to  a
solid,  stationary,  unpainted  meta llic  point  away  from  the  battery

Start  the  engine  of  the  second  vehicle.  Increase  the  engine  speed
slightly  and  maintain  at  that  lev el  for  approximately  5  minutes to
recharge the batter y of your vehicle.
Vehicles with a smart key syst em: Open and close any of the doo rs
of your vehicle with the engine switch off.
Vehicles without a smart key system: 
Maintain  the  engine  speed  of  the  second  vehicle  and  turn  the
engine switch to the “ON” posit ion, then start the vehicle's engine.
Vehicles with a smart key system: 
Maintain  the  engine  speed  of  the  second  vehicle  and  turn  the
engine  switch  to  IGNITION  ON  mode,  then  start  the  vehicle's
engine.
Once the vehicle’s engine has st arted, 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 t he battery 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 running
at a low speed for an extended period, such as in heavy traffic .
■ When the battery is removed or discharged
●Information stored in the ECU is cleared. When the battery is d epleted, have
the vehicle inspected at your Toyota dealer.
● Some systems may require initialization. (→P. 614)
■ When removing the battery terminals
When the battery terminals are removed, the information stored  in the ECU is
cleared. Before removing the battery terminals, contact your Toyota dealer.
■ Charging the battery
The  electricity  stored  in  the  battery  will  discharge  gradually  even  when  the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long t ime, the battery may
discharge,  and  the  engine  may  be  unable  to  start.  (The  battery  recharges
automatically during driving.)

WARNING
■When removing the  battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts  any  metal  in  the  surrounding  area  when  the  positive  (+)  terminal  is
removed, a spark may occur, leading to a fire in addition to el ectrical shocks
and death or serious injury.
■ Avoiding battery fires or explosions
Observe  the following  precautions  to prevent accidentally ignit ing  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 in tended terminal.
● Do not allow the other end of the jumper cable connected to the  “+” termi-
nal 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 in to contact
with each other.
● Do  not  smoke,  use  matches,  cigarette  lighters  or  allow  open  fla me  near
the battery.
■ Battery precautions
The  battery  contains  poisonous  and  corrosive  acidic  electrolyte ,  while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery:
● 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 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 battery-related parts.
● Do not allow children near the battery.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not beco me entan-
gled in the cooling fan or engine drive belt.
