The power switch is in ACCESSORY or ON mode.
■ When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror d efoggers. Turn
on  the  rear  window  defogger  to  turn  on  the  outside  rear  view  mi rror  defog-
gers. ( P. 440, 450)
WARNING
■Important points while driving
Observe the following precautions while driving.
Failing  to  do  so  may  result  in  loss  of  control  of  the  vehicle  a nd  cause  an
accident, resulting in death or serious injury.
● Do not adjust the mirrors while driving.
● Do not drive with the mirrors folded.
● Both the driver and passenger side mirrors must be extended and  properly
adjusted before driving.
■ When a mirror is moving
To  avoid  personal  injury  and  mirror  malfunction,  be  careful  not   to  get  your
hand caught by the moving mirror.

Driving
Firmly  set  the  parking  brake  with  the  brake  pedal  depressed,  and
then shift the shift position to D.
Release the brake ped al and gently depress the accelerator peda l.
Release the parking brake.
■ When starting off on an uphill
The hill-start assist control will activate. ( P. 421)
■ For fuel-efficient driving
Keep in  mind  that hybrid  vehicles  are similar  to  conventional vehicles,  and  it
is necessary to refrain from activities such as sudden accelera tion. (P. 427)
■ Driving in the rain
●Drive carefully when it is raining, because visibility will be  reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain  from  high  speeds  when  driving  on  an  expressway  in  the  r ain,
because there may be  a layer of  water  between the tires  and  the  road sur-
face, preventing the steering  and brakes from operating properl y.
■ Restraining the hybrid system o utput (Brake Override System)
● When the accelerator and brake pedals are depressed at the same  time, the
hybrid system output may be restrained.
● A  warning  message  is  displayed  on  the  multi-information  display  while the
system is operating. ( P. 608)
■ “ECO Accelerator Guidance” (P. 130)
It is easier to drive in an Eco-friendly manner by driving whil e referring to the
“ECO  Accelerator  Guidance”  display.  Also,  by  using  the  “ECO  Accelerator
Guidance”, it is easier to increase the Eco score evaluation.
● When starting off:
While  staying  within  the  “ECO  Accelerator  Guidance”  range,  gradually
depress the accelerator pedal and accelerate to the desired spe ed. If exces-
sive acceleration is avoided, the “Eco-Start” score will increa se.
● When driving:
After  accelerating  to  the  desired  speed,  release  the  accelerato r  pedal  and
drive  at  a  stable  speed  within  the  “ECO Accelerator  Guidance”  range.  By
keeping the vehicle within the “ECO Accelerator Guidance” range, the “Eco-
Cruise” score will increase.
● When stopping:
When stopping the vehicle, early releasing the accelerator peda l will cause
the “Eco-Stop” score to increase.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the  “READY”
indicator is illuminated. This prevents the vehicle from creepi ng.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal. 
• Accidentally  depressing  the  accelerator  pedal  instead  of  the  b rake
pedal will result in sudden acceleration that may lead to an ac cident.
• When  backing  up,  you  may  twist  your  body  around,  leading  to  a  diffi-
culty in operating the pedals. Make sure to operate the pedals  properly.
• Make  sure  to  keep  a  correct  driving  posture  even  when  moving  t he
vehicle only slightly. This allows you to depress the brake and  accelera-
tor pedals properly.
• Depress  the  brake  pedal  using  your  right  foot.  Depressing  the  brake
pedal using your left foot may delay response in an emergency,  result-
ing in an accident.
● The  driver  should  pay  extra  attention  to  pedestrians  when  the  v ehicle  is
powered only  by the electric  motor (traction motor). As there i s  no engine
noise,  the  pedestrians  may  misjudge  the  vehicle’s  movement.  Eve n
though  the  vehicle  is  equipped  with  the  vehicle  proximity  notif ication  sys-
tem,  drive  with  care  as  pedestrians  in  the  vicinity  may  still  n ot  notice  the
vehicle if the surrounding area is noisy.
● Do not drive the vehicle over or stop the vehicle near flammabl e materials
such as leaves, paper or rags. 
The  exhaust  system  and  exhaust  gases  can  be  extremely  hot. Thes e  hot
parts may cause a fire if there is any flammable material nearby.
● During normal driving, do not turn off the hybrid system. Turni ng the hybrid
system  off  while  driving  will  not  cause  loss  of  steering  or  bra king  control,
however,  power  assist  to  the  steering  will  be  lost.  This  will  m ake  it  more
difficult to steer smoothly, so you should pull over and stop t he vehicle as
soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 581

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● Use engine braking (shift position B instead of shift position D) to maintain
a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat  and lose
effectiveness. ( P. 256)
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving. 
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, head or other parts of  their body
are not outside the vehicle.
● AWD models: Do not drive the vehicle off-road.
This is not an AWD  vehicle designed  for  off-road driving.  Proce ed with  all
due caution if it becomes unavoidable to drive off-road.
● Do not drive across river crossings or through other bodies of  water. 
This  may  cause  electric/electronic  components  to  short  circuit,   damage
the hybrid system or cause other serious damage to the vehicle.
● Do not drive in excess of the speed limit. Even if the legal sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed  capability  tires.  Driving  over  85  mph  (140  km/h)  may  resu lt  in  tire
failure,  loss  of  control  and  possible  injury.  Be  sure  to  consult  a  tire  dealer
to  determine  whether  the  tires  on  your  vehicle  are  high-speed  c apability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden  braking,  acceleration  and  steering  may  cause  tire  slippa ge  and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes  in engine
speed could cause the vehicle to skid, resulting in an accident .
● After driving through a puddle, depress the brake pedal to make  sure that
the  brakes  are  functioning  properly.  Wet  brake  pads  may  prevent  the
brakes  from  functioning  properly.  If  the  brakes  on  only  one  sid e  are  wet
and not functioning properly, steering control may be affected.

● Do  not  use  the  accelerator  pedal  or  depress  the  accelerator  and  brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always  set the  parking  brake, and shift  the shift  position to  P . Failure to  do
so may cause the vehicle to move or the vehicle may accelerate  suddenly if
the accelerator pedal is accidentally depressed.
■ Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and ho ld it there for
an extended period of time. 
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possibl e to avoid
damaging the wheels, underside of the vehicle, etc. 
■ If you get a flat tire while driving 
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly  and  gradually  depress  the  brake  pedal to  slow  down  the  vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.

depress  the  accelerator  pedal  while  starting  the  hybrid  system  under  any
circumstances. 
Doing so may cause an accident resulting in death or serious in jury.
■ Stopping the hybrid system in an emergency
● If  you  want  to  stop  the  hybrid  system  in  an  emergency  while  dri ving  the
vehicle,  press  and  hold  the  power  switch  for  more  than  2  second s,  or
press it briefly 3 times or more in succession. ( P. 581)
However,  do  not  touch  the  power  switch  while  driving  except  in  an  emer-
gency.  Turning  the  hybrid  system  off  while  driving  will  not  cau se  loss  of
steering  or  braking  control,  however,  power  assist  to  the  steer ing  will  be
lost.  This  will  make  it  more  difficult  to  steer  smoothly,  so  yo u  should  pull
over and stop the vehicle as soon as it is safe to do so.
● If  the  power  switch  is  operated  while  the  vehicle  is  running,  a   warning

■ When parking
Exhaust  gases  include  harmful  carbon  monoxide  (CO),  which  is  colorless
and odorless. Observe the following precautions.
Failure  to  do  so  may  cause  exhaust  gases  to  enter  the  vehicle  a nd  may
lead to an accident caused by light-headedness, or may lead to  death or a
serious health hazard.
● If  the  vehicle  is  in  a  poorly  ventilated  area  or  a  closed  area,  such  as  a
garage, stop the hybrid system.
● Do not leave the vehicle with the hybrid system operating for a long time. If
such a situation cannot be avoided, park the vehicle in an open space and
ensure that exhaust fumes do not enter the vehicle interior.
● Do not leave the hybrid system operating in an area with snow build-up, or
where  it  is  snowing.  If  snowbanks  build  up  around  the  vehicle  w hile  the
hybrid system is operating, exhaust gases may collect and enter  the vehi-
cle.
