When the mirror select switch is in the L or R position, the outside rear
view  mirrors  will  automatically  angle  downwards  when  the  vehicle  is
reversing in order to give a better view of the ground. 
To  disable  this  function,  move  the  mirror  select  switch  to  the  neutral
position (between L and R).
■Adjusting the mirror angle when the vehicle is reversing
With  the  shift  lever  in  R,  adjust  the  mirror  angle  at  a  desired  posi-
tion. The adjusted angle will be memo rized and the mirror will auto-
matically  tilt  to  the  memorized  angle  whenever  the  shift  lever  is
shifted to R from next time.
The memorized downward tilt position of the mirror is linked to the nor-
mal position (angle adjusted with the shift lever in other than R). There-
fore,  if  the  normal  position  is  changed  after  adjustment,  the  tilt  position
will also change.
When the normal position is changed, readjust the angle in reversing.

■Mirror angle can be adjusted when
Vehicles without a smart key system 
The engine switch is in the “ACC” or “ON” position. 
Vehicles with a smart key system 
The engine switch is in ACCESSORY or IGNITION ON mode.
■ When the mirrors are fogged up (vehicles with outside rear view mirror
defoggers)
The outside rear view mirrors can be  cleared using the mirror defoggers. Turn
on  the  rear  window  defogger  to  turn  on  the  outside  rear  view  mirror  defog-
gers. ( P. 412)
■ Automatic adjustment of the mirror angle (vehicles with driving position
memory)
A desired mirror face angle can be entered to memory and recalled automati-
cally by the driving position memory. (P. 169)
■ Auto anti-glare function (vehicles with auto anti-glare inside rear view
mirror)
When the anti-glare inside rear view mirr or is set to automatic mode, the out-
side  rear  view  mirrors  will  activate  in  conjunction  with  the  anti-glare  inside
rear view mirror to reduce reflected light. ( P. 179)
WARNING
■When driving the vehicle
Observe the following precautions while driving.
Failing  to  do  so  may  result  in  loss  of  control  of  the  vehicle  and  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.
■ When the mirror defoggers are opera ting (vehicles with outside rear
view mirror defoggers)
Do  not  touch  the  rear  view  mirror  surfaces,  as  they  can  become  very  hot
and burn you.

WARNING
Observe the following precautions. 
Failure to do so may result in death or serious injury.
■When driving the vehicle
●During  normal  driving,  do  not  turn  off  the  engine.  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 over and stop the vehicle as soon as it
is safe to do so. 
However, in  the  event of  an emergency, such  as if  it becomes  impossible
to stop the vehicle in the normal way:  P. 533
● Use  engine  braking  (downshift)  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. 234)
● Do  not adjust the  position 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, heads 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. Proceed with all
due caution if it becomes unavoidable to drive off-road.
● AWD models: Do not drive across a river or through other bodies of water.
This  may  cause  electric/electronic  components  to  short  circuit,  damage
the engine or cause other serious damage to the vehicle.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph ( 140 km/h) unless your vehicle has high-
speed  capability  tires.  Driving  over  85  mph  (140  km/h)  may  result  in  tire
failure,  loss  of  control  and  possible  injury.  Be  sure  to  consult  a  tire  dealer
to  determine  whether  the  tires  on  y our  vehicle  are  high-speed  capability
tires or not before driving at such speeds.

NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain the engine output.
● 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  shift  the  shift  lever  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 hold 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 possible 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.
Information on what to do in case of a flat tire. ( P. 566, 568)
■ When encounterin g flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes  in  quantity  and  quality  of  oil  and  fluid  used  for  the  engine,  tran-
saxle, transfer (AWD models), rear differential (AWD models), etc.
● Lubricant  condition  for  the  bearings  and  suspension  joints  (where  possi-
ble) and the function of all joints, bearings, etc.

●Reversing with a trailer attached is difficult and requires practice. 
Grip  the  bottom  of  the  steering  wheel  and  move  your  hand  to  the
left  to  move  the  traile r  to  the  left.  Move  your  hand  to  the  right  to
move the trailer to the right. (This is generally opposite to reversing
without  a  trailer  attached.)  Avoid  sharp  or  prolonged  turning.  Have
someone  guide  you  when  reversing  to   reduce  the  risk  of  an  acci-
dent.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle  distance  should  be  increa sed.  For  each  10  mph  (16  km/h)
of speed, allow at least one vehicle and trailer length.
● Avoid sudden braking as  you may skid, resulting in the trailer jack-
knifing and a loss of vehicle contro l. This is especially true on wet or
slippery surfaces.
● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making
a turn.
● Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a wider than normal turning radius.
● Slow down before making a turn, in crosswinds, on wet or slippery
surfaces, etc. 
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able  distance.  After  passing  a  vehicle,  do  not  forget  the  length  of
your  trailer,  and  be  sure  you  hav e  plenty  of  room  before  changing
lanes.
● To  maintain  engine  braking  effici ency  and  charging  system  perfor-
mance  when  using  engine  braking,  do  not  put  the  transmission  in
D. If in the S mode, transmission shift range position must be in 4 or
lower.
● Instability happens more  frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause th e brakes to overheat and result in
reduced braking efficiency.

■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due
to  the  additional  load.  (See  “Scheduled  Maintenance  Guide”  or  “Owner’s
Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
■ If trailer sway occurs
One  or  more  factors  (crosswinds,  passing  vehicles,  rough  roads,  etc.)  can
adversely affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead. 
Do not try to control trailer swaying by turning the steering wheel.
• Begin  releasing  the  accelerator  pedal  immediately  but  very  gradually  to reduce speed. 
Do not increase speed. Do not apply vehicle brakes.
If  you  make  no  extreme  correction  with  the  steering  or  brakes,  your  vehicle
and trailer should stabilize.
● After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer. 
Make sure the load has not shifted. 
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.  Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred
is beyond the limit of your particular vehicle-trailer combination. 
Drive  at  a  lower  speed  to  prevent  instability.  Remember  that  swaying  of  the
towing vehicle-trailer increases as speed increases.
