741-1. For safe use
SIENNA_OM_OM08007U_(U)
Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an  accident  caused  by  light-headedness,  or  may  lead  to  death  or  a  serious
health hazard.
■Important points while driving
●Keep the back door closed.
● If  you  smell  exhaust  gases  in  the  vehicle  even  when  the  back  door  is
closed,  open  the  windows  and  have  the  vehicle  inspected  at  your  Toyota
dealer as soon as possible.
■ When parking
●If  the  vehicle  is  in  a  poorly  ventilated  area  or  a  closed  area,  such  as  a
garage, stop the engine.
● Do not leave the vehicle with the engine on 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 engine running in an area with snow build-up, or where it
is  snowing.  If  snowbanks  build  up  around  the  vehicle  while  the  engine  is
running, exhaust gases may collect and enter the vehicle.
■ Exhaust pipe
The  exhaust  system  needs  to  be  checked  periodically.  If  there  is  a  hole  or
crack caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.

cators will turn off after a few seconds.

change  the  brightness  level  of
night mode.
■ Outside temperature display
●In  the  following  situations,  the  correct  outside  temperature  may  not  be  dis-
played, or the display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])
• When  the  outside  temperature  has  changed  suddenly  (at  the  entrance/
exit of a garage, tunnel, etc.)
● The temperature range that can be displa yed is from -40°F (-40°C) to 122°F
(50°C). 
Vehicles with monochrome display
When  the  outside  temperature  drops  below  37°F  (3°C),  the  temperature
display flashes 10 times.
Vehicles with color display
When  the  outside  temperature  drops  below  37°F  (3°C),  the  ICE  warning
indicator will be displayed on the multi-information display. ( P. 84)
● When “--” or “E” is displayed, the system may be malfunctioning. Take your
vehicle to your Toyota dealer.

NOTICE
■ To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in  the  red  zone  (H).  In  this  case,  immediately  stop  the  vehicle  in  a  safe
place, and check the engine after it has cooled completely. (P. 594)

■ In order to correctly use the dr iving position memory function
If  a  seat  position  is  already  in  the  furthest  possible  position  and  the  seat  is
operated in the same direction, the recorded position may be slightly different
when it is recalled.
Each  electronic  key  can  be  registered  to  recall  your  preferred  driving
position.
■Registering procedure

Driving
WARNING
Observe the following precautions. 
Failure to do so may result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible. 
Rotor damage may result if the pads are not replaced when needed.
It  is  dangerous  to  drive  the  vehicle  when  the  wear  limits  of  the  brake  pads
and/or those of the brake discs are exceeded.
■ When the vehicle is stopped
●Do not race the engine. 
If the vehicle is in any gear other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing  the  brake  pedal  while  the  engine  is  running,  and  apply  the
parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine. 
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.
■ When the vehicle is parked
●Do  not  leave  glasses,  cigarette  lighters,  spray  cans,  or  soft  drink  cans  in
the vehicle when it is in the sun. 
Doing so may result in the following:
• Gas  may  leak  from  a  cigarette  lighter  or  spray  can,  and  may  lead  to  a
fire.
• The  temperature  inside  the  vehicle  may  cause  the  plastic  lenses  and plastic material of glasses to deform or crack.
• Soft  drink  cans  may  fracture,  causing  the  contents  to  spray  over  the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
