When trouble arises
■When recharging or replacing the 12-volt battery 
● In  some  cases,  it  may  not  be  possible  to  unlock  the  doors  using  the  smart 
entry  &  start  system  when  the  12-volt  battery  is  discharged.  Us e  the  wire- 
less remote control or the mechanical key to lock or unlock the  doors. 
● The hybrid system may not start on the first attempt after the 12-volt battery 
has recharged but will start normally after the second attempt.  This is not a 
malfunction. 
● The power switch mode is memorized by the vehicle. When the 12-volt bat- 
tery  is  reconnected,  the  system  will  return  to  the  mode  it  was  in  before  the 
12-volt  battery  was  discharged.  Before  disconnecting  the  12-vol t  battery, 
turn the power switch off.  
If you are unsure what mode the power switch was in before the  12-volt bat- 
tery discharged, be especially careful when reconnecting the 12 -volt battery. 
■ When replacing the 12-volt battery
2ZR-FXE engine 
● Use a 12-volt battery that conforms to European regulations. 
● Use a 12-volt battery that the case size is same as the previous one (LN1), 
20  hour  rate  capacity  (20HR)  is  equivalent  (45Ah)  or  greater,  a nd  perfor- 
mance rating (CCA) is equivalent (286A) or greater. 
• If the sizes differ, the 12-volt battery cannot be properly se cured. 
• If the 20 hour rate capacity is low, even if the time period w here the vehi- 
cle is not used is a short time, the 12-volt battery may discha rge and the 
hybrid system may not be able to start. 
● For  details,  consult  any  authorized  Toyota  retailer  or  Toyota  authorized 
repairer, or any reliable repairer.

C-HR_HV_OM_Europe_OM10720E
M20A-FXS engine 
● Use a Central Degassing type 12-volt battery (European Regulations). 
● Use a 12-volt battery that the case size is same as the previous one (LN1), 
20  hour  rate  capacity  (20HR)  is  equivalent  (45Ah)  or  greater,  a nd  perfor- 
mance rating (CCA) is equivalent (286A) or greater. 
• If the sizes differ, the 12-volt battery cannot be properly se cured. 
• If an improper 12-volt battery is used, battery performance ma y decrease 
and the hybrid system may not be able to restart. 
• If the 20 hour rate capacity is low, even if the time period w here the vehi- 
cle is not used is a short time, the 12-volt battery may discha rge and the 
hybrid system may not be able to start. 
● Use  a  12-volt  battery  with  a  handle.  If  a  12-volt  battery  without  a  handle  is 
used, removal is more difficult. 
● After  replacing,  firmly  attach  the  following  items  to  the  exhaust  hole  of  the 
12-volt battery. 
● For  details,  consult  any  authorized  Toyota  retailer  or  Toyota  authorized 
repairer, or any reliable repairer. 
Exhaust hole plug 
Exhaust hole
Exhaust hose
• Use  the  exhaust  hose  that  was 
attached  to  the  12-volt  battery  before 
replacing  and  confirm  that  it  is  firmly
connected  to  the  hole  section  of  the 
vehicle. 
• Use  the  exhaust  hole  plug  included
with  the  12-volt  battery  replaced  or 
the  one  installed  on  the  12-volt  bat- 
tery  prior  to  the  replacement.
(Depending  on  the  12-volt  battery  to 
be replaced, the exhaust hole may be 
plugged.)

When trouble arises
WARNING
■When removing the 12-volt battery terminals 
Always remove the negative (-) terminal first. If the positive  (+) terminal con- 
tacts  any  metal  in  the  surrounding  area  when  the  positive  (+)  t erminal  is 
removed, a spark may occur, leading to a fire in addition to el ectrical shocks 
and death or serious injury. 
■ Avoiding 12-volt battery fires or explosions 
Observe  the  following precautions  to  prevent  accidentally  ignit ing the flam- 
mable gas that may be emitted from the 12-volt 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 into contact 
with each other. 
● Do  not  smoke,  use  matches,  cigarette  lighters  or  allow  open  flame  near 
the 12-volt battery. 
■ 12-volt battery precautions 
The  12-volt  battery  contains  poisonous  and  corrosive  acidic  ele ctrolyte, 
while related parts contain lead and lead compounds. Observe th e following 
precautions when handling the 12-volt battery: 
● When  working  with  the  12-volt  battery,  always  wear  safety  glasses  and 
take  care  not  to  allow  any  battery  fluids  (acid)  to  come  into  c ontact  with 
skin, clothing or the vehicle body. 
● Do not lean over the 12-volt 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 medica l attention 
can be received. 
● Always wash your hands after handling the 12-volt battery support, termi- 
nals, and other battery-related parts. 
● Do not allow children near the 12-volt battery.

C-HR_HV_OM_Europe_OM10720E
WARNING
■After recharging the 12-volt battery (M20A-FXS engine) 
Have  the  12-volt  battery  inspected  at  any  authorized  Toyota  ret ailer  or 
Toyota  authorized  repairer,  or  any  reliable  repairer  as  soon  as   possible.  If 
the  12-volt  battery  is  deteriorating,  continued  use  may  cause  t he  12-volt 
battery to emit a malodorous gas, which may be detrimental to t he health of 
passengers. 
■ When replacing the 12-volt battery 
● When  the  vent  plug  and  indicator  are  close  to  the  hold  down  clamp,  the 
battery fluid (sulfuric acid) may leak. 
● For information regarding 12-volt  battery  replacement, contact any autho- 
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer. 
● M20A-FXS  engine:  After  exchanging,  securely  attach  the  exhaust hose 
and  exhaust  hole  plug  to  the  exhaust  hole  of  the  exchanged  12-v olt  bat- 
tery.  If  not  properly  installed,  gases  (hydrogen)  may  leak  into   the  vehicle 
interior, and there is the possible danger of the gas igniting  and exploding.
NOTICE
■When handling jumper cables 
When connecting the jumper cables, ensure that they do not beco me entan- 
gled in the cooling fans, etc. 
■ To prevent damaging the vehicle (M20A-FXS engine) 
The exclusive jump starting terminal is to be used when chargin g the 12-volt 
battery  from  another  vehicle  in  an  emergency.  It  cannot  be  used  to jump 
start another vehicle.

WARNING
■Cautions during customization 
As  the  hybrid  system  needs  to  be  operating  during  customization ,  ensure 
that  the  vehicle  is  parked  in  a  place  with  adequate  ventilation . In a closed 
area  such  as  a  garage,  exhaust  gases  including  harmful  carbon  m onoxide 
(CO) may collect and enter the vehicle. This may lead to death  or a serious 
health hazard.
NOTICE
■ During customization 
To prevent 12-volt battery discharge, ensure that the hybrid sy stem is oper- 
ating while customizing features.
