WARNING
■To avoid accident or injury
●Do not use cruise control when towing.
● Slow  down  and  downshift  before  descending  steep  or  long  downhill
grades.  Do  not  make  sudden  downshifts  while  descending  steep  or  long
downhill grades.
● Vehicle-trailer  instability  is  more  likely  on  steep  long  downhills.  Before
descending  steep  or  long  downhill  grades,  slow  down  and  downshift.  Do
not  make  sudden  downshifts  when  descending  steep  or  long  downhill
grades.  Avoid  holding  the  brake  pedal  down  too  long  or  applying  the
brakes too frequently.  This  could cause  the  brakes  to overheat and result
in reduced braking efficiency.
● Vehicles  with  compact  spare  tire:  Do  not  tow  a  trailer  when  the  compact
spare tire is installed on your vehicle.
■ Hitch
Trailer hitch assemblies have different weight capacities established by the
hitch  manufacturer.  Even  though  the  vehicle  may  be  physically  capable  of
towing  a  higher  weight,  the  operator  must  determine  the  maximum  weight
rating  of  the  particular  hitch  assembly  and  never  exceed  the  maximum
weight rating specified  for the trailer-hitch. Exceeding the maximum weight
rating  set  by  the  trailer-hitch  manufacturer  can  cause  an  accident  resulting
in death or serious personal injuries.
■ When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
●If  the  gross  trailer  weight  exceeds  unbraked  TWR,  trailer  brakes  are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never  tap  into  your vehicle’s  hydraulic system,  as  this  will  lower the  vehi-
cle’s braking effectiveness.
● Never  tow  a  trailer  without  using  a  safety  chain  securely  attached  to  both
the  trailer  and  the  vehicle.  If  damage  occurs  to  the  coupling  unit  or  hitch
ball, there is danger of the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
Use  only  the  position  recommended  by  your  Toyota  dealer.  Do  not  install
the trailer hitch on the bumper; this may cause body damage.
■ Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage
your vehicle’s electrical system and cause a malfunction.

Driving
The fixed guide lines are very far out of alignment
The  camera  position  is  out  of  align-
ment.Have  the  vehicle  inspected  by  your
Toyota dealer.
• The  vehicle  is  tilted  (there  is  a
heavy  load  on  the  vehicle,  tire
pressure is low due to a tire punc-
ture, etc.)
• The vehicle is used on an incline.If this happens due to these causes,
it does not indicate a malfunction.
Back  up  while  visually  checking  the
vehicle’s surroundings.
WARNING
■ When using the rear  view monitor system 
The  rear  view  monitor  system  is  a  supplemental  device  intended  to  assist
the  driver  when  backing  up.  When  backing  up,  be  sure  to  check  visually
behind and all around the vehicle before proceeding.
Observe  the  following  precautions  to  avoid  an  accident  that  could  result  in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be  sure  to  back  up  slowly,  depressing  the  brake  pedal  to  control  vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic  conditions,  road  surface  conditions,  vehicle  condition,  etc.  when  park-
ing.  It  is  necessary  to  be  fully  aware  of  this  before  using  the  rear  view
monitor system. 
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire (if equipped)
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes.

Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as  excessive wear on one side of the
tread. Check the spare tire condi tion and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” marks,
etc., molded into the sidewall of each tire. 
Replace the tires if the treadwear indicators are showing on a tire.
Rotate  the  tires  in  the  order
shown.
To  equalize  tire  wear  and  extend
tire  life,  Toyota  recommends  that
tire  rotation  is  carried  out  at  the
same interval as tire inspection.
Replace or rotate tires in acco rdance with maintenance sched-
ules and treadwear.

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses
tire  pressure  warning  valves  and  tr ansmitters  to  detect  low  tire  infla-
tion pressure before serious problems arise. ( P. 547)
Vehicles  with  compact  spare  tire :  The  compact  spare  tire  is  not
equipped with the tire pressure warning valve and transmitters.
◆Installing tire pressure warning valves and transmitters
When  replacing  tires  or  wheels,  tire  pressure  warning  valves  and
transmitters must also be installed.
When  new  tire  pressure  warning  valves  and  transmitters  are
installed,  new  ID  codes  must  be  registered  in  the  tire  pressure
warning  computer  and  the  tire  pr essure  warning  system  must  be
initialized.  Have  tire  pressure  warning  valve  and  transmitter  ID
codes registered by your Toyota dealer. ( P. 498)
◆Initializing the tire pressure warning system
When  the  tire  size  is  changed,  the  tire  pressure  warning  system
must be initialized.
When the tire pressure warning system is initialized,  the current tire
inflation pressure is set as the benchmark pressure.
■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot  be performed while the vehicle is moving.
Adjust the tire inflation pressure to  the specified cold tire inflation
pressure level. ( P. 606)
Make  sure  to  adjust  the  tire  pressu re  to  the  specified  cold  tire infla-
tion  pressure  level.  The  tire  pressure  warning  system  will  operate
based on this pressure level.
Turn  the  engine  switch  to  the  “ON”  position  (vehicles  without  a
smart key system) or IGNITION ON mode (vehicles with a smart
key system).

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train, as well as dangerous han-
dling characteristics, which may lead to an accident resulting in death or
serious injury.
●Do not mix tires of different ma kes, models or tread patterns. 
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do  not  mix  differently  constructed  ti res  (radial,  bias-belted  or  bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have b een used on another vehicle. 
Do not use tires if you do not know how they were used previously.
●Vehicles  with  a  compact  spare  tire:  Do  not  tow  if  your  vehicle  has  a
compact spare tire installed.
■When initializing the tire pressure warning system
Do  not  operate  the  tire  pressure  warning  reset  switch  without  first
adjusting the tire inflation pressure to the specified level. Otherwise, the
tire  pressure  warning  light  may  not  come  on  even  if  the  tire  inflation
pressure  is  low,  or  it  may  come  on  when  the  tire  inflation  pressure  is
actually normal.
