WARNING
●Do  not  rely  solely  upon  the  Simple  Intelligent  Parking Assist  System. As 
with  unequipped  vehicles,  move  forward  and  back  up  carefully  wh ile 
directly confirming the safety of your surroundings and the are a to the rear 
of the vehicle. 
● Do  not  back  up  while  viewing  the  multi-information  display.  Backing  up 
while only viewing the  monitor  screen may cause  a collision  or  lead to an 
accident,  as  the  image  displayed  on  the  monitor  screen  may  diff er  from 
actual  conditions.  Make  sure  to  visually  check  the  surrounding  areas  and 
the area to the rear of the vehicle with and without the mirror  while backing 
up. 
● Drive  slowly  while  adjusting  your  speed  by  depressing  the  brake  pedal 
when backing up or moving forward. 
● If  it seems  the vehicle may make  contact with  a pedestrian, another vehi- 
cle or any other obstacles, stop the vehicle by depressing the  brake pedal, 
and then press the S-IPA switch to turn off the system. 
● Use the system in a parking lot with a flat surface. 
● Observe  the  following  precautions,  as  the  steering  wheel  automatically 
turns during use. 
• There  is  risk  of  a  necktie,  scarf,  your  arm,  etc.,  being  caugh t  on  the 
steering wheel. Please do not allow your upper body to be close  to the 
steering wheel. Also, do not allow children close to the steeri ng wheel. 
• There is a possibility of injury when the steering wheel turns  if you have 
long fingernails. 
• In  case  of  emergency,  stop  the  vehicle  by  depressing  the  brake  pedal, 
and then press the S-IPA switch to turn off the system.

WARNING
●Make sure to observe the following precautions regarding the exit parallel 
parking assist mode. 
Exit parallel parking assist mode is a function used when depar ting from a 
parallel  parking  spot.  However,  this  function  may  not  be  usable   if  obsta- 
cles  or  people  are  detected  in  front  of  the  vehicle.  Only  use  t his  function 
when departing from a parallel parking spot. In the event that  the steering 
control operates, either turn the system off using the S-IPA sw itch or oper- 
ate the steering wheel to stop the control. 
● If exit parallel parking assist mode is mistakenly used in the following situ- 
ations, the vehicle may make contact with an obstacle. 
The  departure  function  is  operated  in  a  direction  where  an  obst acle  is 
present,  but  the  obstacle  is  not  detected  by  the  side  sensors  ( situations 
such as when the vehicle is directly beside a pole). 
● Observe  the  following  precautions,  as  the  sensors  may  stop  functioning 
properly which may lead to an accident. 
• Do  not  subject  the  sensor  to  strong  shocks  by  hitting  it,  etc.   The  sen- 
sors may not function properly. 
• When  using  a  high-pressure  washer  to  wash  the  vehicle,  do  not  spray 
water  directly  on  the  sensors.  Equipment  may  not  function  prope rly  if 
subjected  to  an  impact  from  strong  water  pressure.  If  the  vehic le 
bumper  strikes something,  equipm ent  may  not  operate  properly due  to 
a  sensor  malfunction.  Have  the  vehicle  inspected  at  any  authori zed 
Toyota retailer or Toyota author ized repairer, or any reliable repairer.

Driving assist systems
◆ECB (Electronically Controlled Brake System) 
The electronically controlled system generates braking force co rre- 
sponding to the brake operation 
◆ABS (Anti-lock Brake System) 
Helps to prevent wheel lock when the brakes are applied suddenl y, 
or if the brakes are applied while driving on a slippery road s urface
◆Brake assist 
Generates an increased level of braking force after the brake p edal 
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control) 
Helps  the  driver  to  control  skidding  when  swerving  suddenly  or 
turning on slippery road surfaces
To  keep  driving  safety  and  performance,  the  following  systems 
operate  automatically  in response  to  various  driving  situations . 
Be  aware,  however,  that  these  systems  are  supplementary  and 
should  not  be  relied  upon  too  heavily  when  operating  the  vehi-
cle.

◆VSC + (Vehicle Stability Control +) 
Provides  cooperative  control  of  the  ABS,  TRC,  VSC  and  EPS. 
Helps  to  maintain  directional  stability  when  swerving  on  slippe ry 
road surfaces by controlling steering performance.
◆TRC (Traction Control)  
Helps  to  maintain  drive  power  and  prevent  the  drive  wheels  from 
spinning when starting the vehicle or accelerating on slippery  roads
◆Active Cornering Assist (ACA) 
Helps  to  prevent  the  vehicle  from  drifting  to  the  outer  side  by   per- 
forming  inner  wheel  brake  control  when  attempting  to  accelerate 
while turning.
◆Hill-start assist control 
Helps to reduce the backward movement of the vehicle when start - 
ing on an uphill
◆EPS (Electric Power Steering)  
Employs an electric motor to reduce the amount of effort needed  to 
turn the steering wheel
◆Trailer Sway Control 
Helps the driver to control trailer sway by selectively applyin g brake 
pressure  for  individual  wheels  and  reducing  driving  torque  when 
trailer sway is detected.

■ Active Cornering Assist operation sounds and vibrations 
When  the Active  Cornering Assi st  is  operated,  operation  sounds and  vibra- 
tions may be generated from the brake system, but this is not a  malfunction. 
■ EPS operation sound 
When the steering wheel is operated, a motor sound (whirring so und) may be 
heard. This does not indicate a malfunction. 
■ Automatic reactivation of TRC, Trailer Sway Control and VSC systems 
After  turning  the  TRC,  Trailer  Sway  Control  and  VSC  systems  off ,  the  sys- 
tems will be automatically re- enabled in the following situations: 
● When the power switch is turned off 
● If  only  the  TRC  system  is  turned  off,  the  TRC  will  turn  on  when  vehicle 
speed increases 
If both the TRC and VSC systems are turned off, automatic re-en abling will 
not occur when vehicle speed increases. 
■ Operating conditions of Active Cornering Assist 
The system operates when the following occurs: 
● TRC/VSC can operate 
● The driver is attempting to accelerate while turning 
● The system detects that the vehicle is drifting to the outer side 
● The brake pedal is released 
■ Reduced effectiveness of the EPS system 
The  effectiveness  of  the  EPS  system is reduced  to prevent  the  s ystem  from 
overheating when there is frequent steering input over an exten ded period of 
time. The steering wheel may feel heavy as a result. Should thi s occur, refrain 
from  excessive  steering  input  or  stop  the  vehicle  and  turn  the  hybrid  system 
off. The EPS system should return to normal within 10 minutes. 
■ Operating conditions of hill-start assist control 
When  the  following  four  conditions  are  met,  the  hill-start  assi st  control  will 
operate: 
● The  shift  lever  is  in  a  position  other  than  P  or  N  (when  starting  off  forward/ 
backward on an upward incline) 
● The vehicle is stopped 
● The accelerator pedal is not depressed 
● The parking brake is not engaged

WARNING
■Hill-start assist control does not operate effectively when 
● Do  not  overly  rely  on  hill-start  assist  control.  Hill-start  assist  control  may 
not operate effectively on steep inclines and roads covered wit h ice. 
● Unlike the parking brake, hill-start assist control is not intended to hold the 
vehicle  stationary  for  an  extended  period  of  time.  Do  not  attem pt  to  use 
hill-start  assist  control  to  hold  the  vehicle  on  an  incline,  as   doing  so  may 
lead to an accident. 
■ When the TRC/ABS/VSC/Trailer Sway Control is activated 
The slip indicator light flashes. Always drive carefully. Reckl ess driving may 
cause an accident. Exercise particular care when the indicator  light flashes. 
■ When the TRC/VSC/Trailer Sway Control systems are turned off 
Be  especially  careful  and  drive  at  a  speed  appropriate  to  the  r oad  condi- 
tions. As  these  are  the  systems  to  help  ensure  vehicle  stabilit y  and  driving 
force,  do  not  turn  the  TRC/VSC/Trailer  Sway  Control  systems  off   unless 
necessary. 
Trailer Sway Control is part of the VSC system and will not ope rate if VSC is 
turned off or experiences a malfunction. 
■ Replacing tires 
Make  sure  that  all  tires  are  of  the  specified  size,  brand,  trea d  pattern  and 
total  load  capacity.  In  addition,  make  sure  that  the  tires  are  inflated  to  the 
recommended tire inflation pressure level. 
The ABS, TRC, Trailer Sway Control and VSC systems will not fun ction cor- 
rectly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized rep airer, or any 
reliable repairer for further information when replacing tires  or wheels.
