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.

WARNING
■TRAC may not operat e effectively when
Directional  control  and  power  may  not  be  achievable  while  driving  on  slip-
pery road surfaces, even if the TRAC system is operating.
Drive  the  vehicle  carefully  in  conditions  where  stability  and  power  may  be
lost.
■ Hill-start assist control (vehicles with a hill-start assist control system)
●Do  not  overly  rely  on  hill-start  assist  control.  Hill-start  assist  control  may
not operate effectively on steep inclines and roads covered with 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  attempt  to  use
hill-start  assist  control  to  hold  the  vehicle  on  an  incline,  as  doing  so  may
lead to an accident.
■ When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC syst ems are turned off
Be  especially  careful  and  drive  at  a  speed  appropriate  to  the  road  condi-
tions.  As  these  are  the  systems  to  help  ensure  vehicle  stability  and  driving
force, do not turn the TRAC/VSC systems off unless necessary.
■
Replacing tires
Make  sure  that  all  tires  are  of  the  specified  size,  brand,  tread  pattern
and total load capacity. In addition, make sure that the tires are inflated
to the recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not  function correctly if different
tires are installed on the vehicle.
Contact  your  Toyota  dealer  for  further  information  when  replacing  tires
or wheels.
■Handling of tires and suspension
Using  tires  with  any  kind  of  problem  or  modifying  the  suspension  will
affect the driving assist systems,  and may cause the system to malfunc-
tion.
■ Active Torque Control 4WD system (AWD models only)
●The  AWD  system  of  this  vehicle  is  intended  to  ensure  driving  stability  on
normal  roads.  It  is  not  designed  for  use  in  demanding  situations  such  as
rally driving.
● Take care when driving on slippery road surfaces.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing  to  do  so  may  result  in  a  loss  of  vehicle  control  and  cause  death  or
serious injury.
●Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do  not  drive  in  excess  of  75  mph  (120  km/h),  regardless  of  the  type  of
snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing  to  do  so  may  result  in  the  vehicle  being  unable  to  be  driven  safely,
and may cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being
used or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid  sudden  acceleration,  abrupt  steering,  sudden  braking  and  shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
■Repairing or replacing snow tires
Request  repairs  or  replacement  of  snow   tires  from  Toyota  dealers  or  legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
