WARNING
■Road accident cautions 
Observe  the  following  precautions  to  reduce  the  risk  of  death  o r  serious 
injury: 
● Pull  your vehicle  off  the road,  apply the parking brake,  shift the shift  lever 
to P, and turn the hybrid system off. 
● Do not touch the high voltage parts, cables and connectors. 
● If  electric  wires  are  exposed  inside  or  outside  your  vehicle,  an  electric 
shock may occur. Never touch exposed electric wires. 
● 2ZR-FXE engine (for Guadelope, Martinique, F. Guiana and Greenland): If 
a fluid leak occurs, do not touch the fluid as it may be strong  alkaline elec- 
trolyte  from  the  hybrid  battery  (traction  battery).  If  it  comes   into  contact 
with your skin or eyes, wash it off immediately with a large am ount of water 
or, if possible, boric acid solution. Seek immediate medical at tention. 
● 2ZR-FXE  engine  (except  for  Guadelope,  Martinique,  F.  Guiana  and 
Greenland): Do not touch the batte ry if liquid is leaking from or adhering to 
it. If electrolyte (carbonic-based organic electrolyte) from th e hybrid battery 
(traction  battery)  comes  into  contact  with  the  eyes  or  skin,  it   could  cause 
blindness  or  skin  wounds.  In  the  unlikely  event  that  it  comes  i nto  contact 
with the eyes or skin, wash it of f immediately with a large amount of water, 
and seek immediate medical attention. 
● 2ZR-FXE  engine  (except  for  Guadelope,  Martinique,  F.  Guiana  and 
Greenland):  If  electrolyte  is  leaking  from  the  hybrid  battery  ( traction  bat- 
tery),  do  not  approach  the  vehicle.  Even  in  the  unlikely  event  that  the 
hybrid  battery  (traction  battery)  is  damaged,  the  internal  cons truction  of 
the  battery  will  prevent  a  large  amount  of  electrolyte  from  lea king  out. 
However, any electrolyte that does leak out will give off a vap or. This vapor 
is an irritant to skin and eyes and could cause acute poisoning  if inhaled. 
● 2ZR-FXE  engine  (except  for  Guadelope,  Martinique,  F.  Guiana  and 
Greenland):  Do  not  bring  burning  or   high-temperature  items  close  to  the 
electrolyte. The electrolyte may ignite and cause a fire. 
● If a fire occurs in the Hybrid Electric Vehicle, leave the vehicle as soon as 
possible.  Never  use  a  fire  extinguisher  that  is  not  meant  for  e lectric  fires. 
Using even a small amount of water may be dangerous. 
● If  your  vehicle  needs  to  be  towed,  do  so  with  front  wheels  raised.  If  the 
wheels connected to the electric motor (traction motor) are on  the ground 
when  towing,  the  motor  may  continue  to  generate  electricity.  Th is  may 
cause a fire. ( P. 674) 
● Carefully  inspect  the  ground  under  the  vehicle.  If  you  find  that  liquid  has 
leaked onto the ground, the fuel system may have been damaged.  Leave 
the vehicle as soon as possible.

Winter driving tips
●Use  fluids  that  are  appropriate  to  the  prevailing  outside  tempera- 
tures.  
• Engine oil 
• Engine/power control unit coolant 
• Washer fluid 
● Have  a  service  technician  inspect  the  condition  of  the  12-volt bat- 
tery. 
● Have the vehicle fitted with four snow tires or purchase a set of tire 
chains for the front tires*. 
Ensure  that  all  tires  are  the  same  size  and  brand,  and  that  cha ins  match 
the size of the tires.
*: Tire chains cannot be mounted on 18-inch tires or 19-inch tir es.
Perform the following according to the driving conditions: 
● Do not try to forcibly open a window or move a wiper that is frozen. 
Pour  warm  water  over  the  frozen  area  to  melt  the  ice.  Wipe  away 
the water immediately to prevent it from freezing.  
● To  ensure  proper  operation  of  the  climate  control  system  fan, 
remove  any  snow  that  has  accumulated  on  the  air  inlet  vents  in
front of the windshield.  
● Check for and remove any excess ice or snow that may have accu- 
mulated  on  the  exterior  lights,  vehicle’s  roof,  chassis,  around  the 
tires or on the brakes.  
● Remove  any  snow  or  mud  from  the  bottom  of  your  shoes  before

WARNING
The  engine  compartment  contains  many  mechanisms  and  fluids  that  may 
move suddenly, become hot, or become electrically energized. To  avoid death 
or serious injury, observe  the following precautions. 
■ When working on the engine compartment 
● Make  sure  that  the  “ACCESSORY”  or  “IGNITION  ON”  on  the  multi-infor- 
mation display and the “READY” indicator are both off. 
● Keep hands, clothing and tools away from the moving fan. 
● Be  careful  not  to  touch  the  engine,  power  control  unit,  radiator,  exhaust 
manifold,  etc.,  right  after  driving  as  they  may  be  hot.  Oil  and  other fluids 
may also be hot. 
● Do not leave anything that may burn easily, such as paper and rags, in the 
engine compartment. 
● Do not smoke, cause sparks or expose an open flame to fuel or the 12-volt 
battery. Fuel and 12-volt battery fumes are flammable. 
● Be extremely cautious when working on the 12-volt battery. It contains poi- 
sonous and corrosive sulfuric acid. 
● Take care because brake fluid can harm your hands or eyes and damage 
painted  surfaces.  If  fluid  gets  on  your  hands  or  in  your  eyes,  flush  the 
affected area with clean water immediately. If you still experi ence discom- 
fort, consult a doctor. 
■ When working near the electric cooling fans or radiator grille 
Be sure the power switch is off. 
With the power switch in ON mode, the electric cooling fans may  automati- 
cally start to run if the air conditioning is on and/or the coo lant temperature 
is high. ( P. 606) 
■ Safety glasses 
Wear  safety  glasses  to  prevent  flying  or  falling  material,  flui d  spray,  etc., 
from getting in your eyes.
