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. 598)
●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.

Use the correct trailer ball for your application.Trailer ball load rating
Matches  or  exceeds  the  gross
trailer weight rating of the trailer.
Ball diameter
Matches the size of the trailer cou-
pler.  Most  couplers  are  stamped
with the required trailer ball size.
Shank length
Protrudes  beyond  the  bottom  of  the  lock  washer  and  nut  by  at  least  2
threads.
Shank diameter
Matches the ball mount hole diameter size.

4-1. Before driving
●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.
