4-1. Before driving
WARNING
■Cross rail adjustment
Make  sure  the  cross  rails  are  locked  securely  by  pushing  forward  and
rearward them.
Failure to do so may cause an unexpected accident.
■When loading cargo
To use the roof rails as a roof luggage  carrier, you must fit the roof rails
with two or more genuine Toyota cross rails or their equivalent. 
When you load cargo on the roof luggage carrier, observe the following:
●Place  the  cargo  so  that  its  weight  is  distributed  evenly  between  the
front and rear axles.
●If  loading  long  or  wide  cargo,  never  exceed  the  vehicle  overall  length
or width. ( P. 600)
●Before  driving,  make  sure  the  cargo  is  securely  fastened  on  the  roof
luggage carrier.
●Loading cargo on the ro of luggage carrier will make  the center of grav-
ity of the vehicle higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failu re to operate this vehicle correctly
and result in death or serious injury.
●If  driving  for  a  long  distance,  on  rough  roads,  or  at  high  speeds,  stop
the  vehicle  now  and  then  during  the  trip  to  make  sure  the  cargo
remains in its place.
●Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo (vehicles with moon roof)
Be careful not to scratch the surface of the moon roof.

4-5. Using the driving support systems
■Screen description
The  rear  view  monitor  system  screen  will  be  displayed  if  the  shift
lever  is  shifted  to  R  while  the  engi ne  switch  is  in  the  “ON”  position
(vehicles without a smart key syst em) or IGNITION ON mode (vehi-
cles with a smart key system).
Vehicle width guide line
The  line  indicates  a  guide  path  when  the  vehicle  is  being  backed  straight
up.
The displayed width is wider than the actual vehicle width.
Vehicle center guide line
These lines indicate the estimated vehicle center on the ground.
Distance guide line
The  line  shows  distance  behind  the  vehicle,  a  point  approximately  1.5  ft.
(0.5 m) (red) from the edge of the bumper.
Distance guide line
The  line  shows  distance  behind  the  vehicle,  a  point  approximately  3  ft.
(1 m) (blue) from the edge of the bumper.

4-5. Using the driving support systems
■Rear view monitor system camera
The  camera  for  the  rear  view
monitor  system  is  located
above the license plate.
●Using the camera
If  dirt  or  foreign  matter  (such  as  water  droplets,  snow,  mud  etc.)
is  adhering  to  the  camera,  it  cannot  transmit  a  clear  image.  In
this case, flush it with a large quantity of water and wipe the cam-
era lens clean with a soft and wet cloth.
■Differences between the screen and the actual road
The distance guide lines and the vehicle width guide lines may not
actually be parallel with the dividing  lines of the parking space, even
when they appear to be so. Be sure to check visually.
The  distances  between  the  vehicle  width  guide  lines  and  the  left
and right dividing lines of the pa rking space may not be equal, even
when they appear to be so. Be sure to check visually.
The  distance  guide  lines  give  a  distance  guide  for  flat  road  sur-
faces.  In  any  of  the  following  situations,  there  is  a  margin  of  error
between  the  fixation  guide  lines  on  the  screen  and  the  actual  dis-
tance/course on the road.

4-5. Using the driving support systems
●When any part of the vehicle sags
When  any  part  of  the  vehicle
sags  due  to  the  number  of
passengers  or  the  distribu-
tion  of  the  load,  there  is  a
margin  of  error  between  the
fixation  guide  lines  on  the
screen  and  the  actual  dis-
tance/course on the road.
■When approaching thre e-dimensional objects
The  distance  guide  lines  are  displa yed  according  to  flat  surfaced
objects (such as the road). It is  not possible to determine the posi-
tion  of  three-dimensional  objects  (such  as  vehicles)  using  the  dis-
tance  guide  lines.  When  approachi ng  a  three-dimensional  object
that  extends outward  (such as  the  flatbed  of  a  truck),  be careful  of
the following.
● Vehicle width guide lines
Visually  check  the  surround-
ings  and  the  area  behind  the
vehicle. In the case shown in
the  illustration ,  the  truck
appears  to  be  outside  of  the
vehicle  width  guide  lines  and
the vehicle does not look as if
it hits the truck. However, the
rear  body  of  the  truck  may
actually  cross  over  the  vehi-
cle  width  guide  lines.  In  real-
ity  if  you  back  up  as  guided
by  the  vehicle  width  guide
lines,  the  vehicle  may  hit  the
truck.

Maintenance and care
Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use  only  Toyota  wheel  nuts  and  wrenches  designed  for  use  with
your aluminum wheels.
● When  rotating,  repairing  or  changi ng  your  tires,  check  that  the
wheel nuts are still tight after  driving 1000 miles (1600 km).
● Be  careful  not  to  damage  the  aluminum  wheels  when  using  tire
chains.
● Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
■When replacing wheels
The  wheels  of  your  vehicle  are  equipped  with  tire  pressure  warning
valves  and  transmitters  that  allow  the  tire  pressure  warning  system  to
provide advanced warning in the event of a loss in tire inflation pressure.
Whenever  wheels  are  replaced,  tire  pressure  warning  valves  and  trans-
mitters must be installed. ( P. 497)
If a wheel is bent, cracked or  heavily corroded, it should be
replaced.
Otherwise, the tire may separate from the wheel or cause a loss
of handling control.
