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  do or  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  o pen  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.

The brightness of the meter panel lights can be adjusted.
Pressing the butto n will adjust the
brightness  of  the  meter  panel
lights.
The  brightness  level  of  the  meters
when  the  surroundings  are  bright
(day  mode)  and  dark  (night  mode)
can  be  adjusted  individually.  How-
ever,  when  in  day  mode,  adjusting
the  brightness  level  will  also
change  the  brightness  level  of
night mode.
■ Outside temperature display
●In  the  following  situations,  the  correct  outside  temperature  ma y  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 k m/h])
• When  the  outside  temperature  has  changed  suddenly  (at  the  entr ance/
exit of a garage, tunnel, etc.)
● The temperature range that can be displayed is from -40°F (-40° C) to 122°F
(50°C). 
When  the  outside  temperature  drops  below  37°F  (3°C),  the  Low  ou tside
temperature  indicator  will  be  displayed  on  the  multi-informatio n  display.
( P. 86)
● 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. 509)

Driving
WARNING
Observe the following precautions. 
Failure to do so may result in death or serious injury.
■If you hear a squealing or scrap ing 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  app ly  the
parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent ac cidents 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 m ay 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  d rink  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  le ad  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  ov er  the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.

4-1. Before driving
■Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 522)
● Trailer  tires  are  inflated  according  to  the  trailer  manufacture r’s  recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on  the trailer.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for imprope r tongue weight,
overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The  rear  view  mirrors  conform  to  all  applicable  federal,  state/provincial  or
local regulations. If they do not, install rear view mirrors ap propriate for tow-
ing purposes.
■ Break-in schedule
If  your  vehicle  is  new  or  equipped  with  any  new  power  train  com ponents
(such  as  an  engine,  transmission,  differential  or  wheel  bearing ),  Toyota  rec-
ommends  that  you  do  not  tow  a  trailer  until  the  vehicle  has  bee n  driven  for
over 500 miles (800 km). 
After  the  vehicle  has  been  driven  for  over  500  miles  (800  km),  you  can  start
towing. However, for the next 500 miles (800 km), drive the veh icle at a speed
of  less  than  50  mph  (80  km/h)  when  towing  a  trailer,  and  avoid  full  throttle
acceleration.

4-2. Driving procedures
WARNING
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do  not depress the
accelerator pedal while starting the engine under any circumsta nces.
Doing so may cause an accident resulting in death or serious in jury.
■ Caution while driving
If the vehicle begins to slide due to engine failure or other c ircumstances, do
not  lock  or  open  the  doors  until  the  vehicle  reaches  a  safe  and   complete
stop.  Activation  of  the  steering  lock  in  this  circumstance  may  lead  to  an
accident, resulting in death or serious injury.
■ Stopping the engine in an emergency
If  you  want  to  stop  the  engine  in  an  emergency  while  driving  th e  vehicle,
press and hold the engine switch for more than 2 seconds, or pr ess it briefly
3 times or more in succession. ( P. 463)
However,  do  not  touch  the  engine  switch  while  driving  except  in   an  emer-
gency. Turning the engine off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be  lost. This will
make  it  more  difficult  to  steer  and  brake,  so  you  should  pull  o ver  and  stop
the vehicle as soon as it is safe to do so.
NOTICE
■ To prevent battery discharge
● Do  not  leave  the  engine  switch  in ACCESSORY  or  IGNITION  ON  mode
for long periods of time without the engine running.
● If the indicator on the engine switch is illuminated, the engin e switch is not
off. When exiting the vehicle, always check that the engine swi tch is off.
● Do not stop the engine when the shift lever is in a position ot her than P. If
the engine is stopped in another shift lever position, the engi ne switch will
not be turned off but instead be turned to ACCESSORY mode. If t he vehi-
cle is left in ACCESSORY mode, battery discharge may occur.
■ When starting the engine
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently,  have the engine
checked immediately.
■ Symptoms indicating a malf unction with the engine switch
If the engine switch seems to be operating somewhat differently  than usual,
such as the switch sticking slightly, there may be a malfunctio n. 
Contact your Toyota dealer immediately.
