NOTICE
●If the road surface has any dips or inclines, the target parking spot cannot
be correctly set. Therefore, the vehicle may be parked at an an gle or may
deviate from the parking spot. In these cases, do not use the parallel park-
ing assist mode.
● When  there  is  a  wall  or  other  obstacle  on  the  inner  side  of  the   parking
space, or when another parked vehicle extends into the road fro m its park-
ing  spot,  the  target  parking  spot  may  be  set  in  a  position  that   juts  out
slightly into the road.
● Depending  on  the  surrounding  environment,  such  as  other  parked  vehi-
cles, the vehicle may be parked at an angle or may deviate from  the park-
ing spot. Manually adjust vehicle alignment as necessary.
● The system provides assistance to guide the vehicle based on po sition of
adjacent  vehicles,  even  if  there  are  obstacles,  bumps,  drops  or  curb
stones in the parking space.
If  it  seems  the  vehicle  may  make  contact,  stop  the  vehicle  by  d epressing
the brake pedal, and then press the S-APGS switch to turn off t he system.
● It may not be possible to detect objects that are low to the gr ound. Directly
confirm  the  safety  of  your  surroundings  and,  if  it  seems  the  vehicle  may
make  contact  with  an  obstacle,  stop  the  vehicle  by  depressing  the  brake
pedal.
● When  the  other  parked  vehicle  is  nar-
row  or  parked  extremely  close  to  the
curb,  assist  control  will  also  guide  the
vehicle to a position close to the curb. 
If  it  seems  the  vehicle  may  make  con-
tact  with  the  curb  or  any  other  obsta-
cles,  or  if  it  seems  the  tire  position  will
deviate  from  the  intended  parking  spot,

where take-off is possible and operates the steering wheel, ass ist control is
stopped at that position.
● Assist control cannot be used if there are no parked vehicles a head, or if the
gap  between  the  front  of  your  vehicle  and  the  vehicle  parked  ahead  is  too
large.

confirm the safety of the area to the rear and around the vehic le
slowly  back  up  while  adjusting  your  speed  by  depressing  the
brake pedal.
Depending  on  the  condition  of  the  parking  space,  steps    to    may
need to be repeated.
When the vehicle is almost entire ly within the target parking spot,
a  high-pitched beep is  emitted  and the  stop  display  is  shown  on
the display ( P. 390), stop the vehicle.
This completes the back-in parking assist mode.
● For  safety,  the  buzzer  sounds  slightly  before  the  vehicle  is
completely  entered  within  the  target  parking  spot.  Further-
more,  at  that  point,  system  operation  will  also  finish.  Firmly
hold  the  steering  wheel  and  slowly  back  up  while  adjusting
your speed by depressing the brake pedal to reach the desired
parking spot.
● Be  sure  to  back  up  while  checking  the  area  to  the  front  and
rear of the vehicle direct ly and by using the mirrors.
■Back-in parking assist m ode operating conditions
● In  order  to  operate  the  function  correctly,  drive  slowly  (at  a  speed  at  which
the vehicle can be quickly stopped).
● In  order  to  operate  the  function  correctly,  drive  slowly  (at  a  speed  at  which
the vehicle can be quickly stopped). Come to a full stop so tha t the center of
the  parking  space  is  nearly  perpendicular  to  the  vehicle,  and  t hen  operate
the S-APGS switch.
● The  function  cannot  be  used  when  the  vehicle  speed  is  approxima tely
19 mph (30 km/h) or higher.
● The  front  side  sensors  and  rear  side  sensors  are  used  to  detect   parked
vehicles  and  determine  the  parking  spot.  Therefore,  when  detection  is  not
possible ( P. 419), guidance is not issued.
● If  there  are  no  parked  vehicles,  the  parking  spot  cannot  be  det ermined.
Therefore, the back-in parking assist mode cannot be operated.
● If  unable  to  detect  the  environment  surrounding  the  parking  space,  the
back-in parking assist mode may not be able to operate.
