Function summary

If a parking space can be detected, you will be guided forward until
you reach the assist control starting position, and then the parallel
parking assist mode can be used. Furthermore, depending on the
parking space and other conditions, multi-turn maneuvering assist
control is also provided if necessary.

Continue  moving  forward
with  the  vehicle  parallel  to
the curb or road, and stop so
that  the  center  of  the  target
parking  spot  appears  nearly
perpendicular  to  the  vehicle.
Then  press  the  S-APGS
switch  1  time  to  select  the
parallel parking assist mode.
Travel  straight  ahead  paral-
lel  with  the  road  or  curb  so
that  the  parking  space  is
detected.
A sound is issued and a display is shown to notify you when the
vehicle  reaches  a  position  where  assist  control  can  be  used  to
begin  backing  up  from,  and  then  when  the  shift  position  is
changed according to guidance provided by the system, steering
wheel auto operation begins.

If the detected parking space or road width (distance to the side of the
road across from the parking space) is narrow, or if there are obstacles
in front of the vehicle, guidance will not be issued.

Parking is complete

This completes the assist mode. Depending on the condition of the
parking space, guidance to starting points for moving forward and back-
ing up, as well as the steering wheel auto operation, are repeated any
time multi-turn maneuvering is necessary following step

from the

time the vehicle begins backing up until parking completes.

Parking

Stop so that the center of the target parking spot appears nearly
perpendicular to vehicle. Then press the S-APGS switch 1 time
and check that the display on the multi-information display
switches to “Parallel Parking”.

●

The mode switches each time the S-APGS switch is pressed.
(

P. 465)

●

When the vehicle speed is approximately 19 mph (30 km/h) or
higher, pressing the S-APGS switch will not cause the screen
to switch to the “Parallel Parking” display.

Travel  straight  ahead  paral-
lel  with  the  road  (or  curb),
and  maintain  a  gap  of
approximately  3.3  ft.  (1  m)
from any parked vehicles.

●

Proceed slowly.

●

The system will begin
searching for a parking
space.

●

While searching for a
space, the turn signal lever
(

P. 345) can be operated

to select a parking space
on the left or right.

●

When  stopping  the  func-
tion,  press  the  S-APGS
switch  once  to  turn  the
function off.

When a beep sounds once
and the stop display (

P. 466)

is shown on the display, stop
the vehicle.

When the shift position is changed to R, a high-pitched beep is
emitted and assist control will start.

●

When the steering wheel auto operation starts, the steering
wheel auto operation display (

P. 466) and assistance level

indicator (



P. 466) will be shown in the display area.

●

To stop assist control, press the S-APGS switch.

Assume  an  ordinary  posture  for  backing  up,  rest  your  hands
lightly on the steering wheel without applying any force, directly
confirm the safety of the area to the rear and around the vehicle,
confirm  that  there  are  no  obstacles  in  the  parking  space,  and
slowly  back  up  while  adjusting  your  speed  by  depressing  the
brake pedal.

●

When backing up too quickly, a sharp beeping sound is emit-
ted and assist control is stopped. (



P. 489)

●

When the vehicle cannot be cleanly entered within the target
parking spot on the first try and multi-turn maneuvering is nec-
essary, proceed to step

When multi-turn maneuvering is not necessary, proceed to
step

may

need to be repeated.

When the vehicle is almost entirely within the target parking spot,
a high-pitched beep is emitted and the stop display is shown on
the display, stop the vehicle.
This completes the parallel parking assist mode.

●

After stopping, feel free to maneuver the vehicle to reach the
desired parking spot.

●

Be sure to back up while checking the area to the front and
rear of the vehicle directly and by using the mirrors.

■

Parallel parking assist mode operating conditions

●

In order to operate the parallel parking assist mode correctly, drive slowly (at
a speed at which the vehicle can be quickly stopped) parallel to the road (or
shoulder) while maintaining a distance of approximately 3.3 ft. (1 m) to any
parked vehicles.

●

The function cannot be used when the vehicle speed is approximately
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. 495), guidance is not issued.

●

If there are no parked vehicles, the parking spot cannot be determined.
Therefore, the parallel parking assist mode cannot be operated.

●

If unable to detect the environment surrounding the parking space, the par-
allel parking assist mode may not be able to operate.

●

Guidance will continue until the vehicle speed meets or exceeds approxi-
mately 19 mph (30 km/h) or the function is turned off using the S-APGS
switch.

■

Timing for pressing the S-APGS switch

In the following cases, the assist mode may also operate during the steps
taken to park using the parallel parking assist mode. However, in these
cases, conduct parking procedures according to the information on the multi-
information display.

●

In step   the S-APGS switch is pressed after already passing over the tar-
get parking spot.
If the vehicle is not stopped in step  , pressing the S-APGS switch 1 time
while  the  vehicle  is  in  motion  allows  you  to  select  “Parallel  Parking”  and
proceed directly to step  .

●

The vehicle is moved up to the position in step

without the S-APGS

switch being pressed. Then the S-APGS switch is pressed after having
changed the shift position to R.

474

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 angle 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 from 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 position 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 depressing
the brake pedal, and then press the S-APGS switch to turn off the system.

●

It may not be possible to detect objects that are low to the ground. 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,
stop  the  vehicle  by  depressing  the
brake  pedal,  and  then  press  the
S-APGS switch to turn off the system.

Exit parallel parking assist mode

●

During assist control, if the driver determines that they are at a position
where take-off is possible and operates the steering wheel, assist control is
stopped at that position.

●

Assist control cannot be used if there are no parked vehicles ahead, or if the
gap between the front of your vehicle and the vehicle parked ahead is too
large.

●

When using the exit parallel parking assist mode, the assist mode may not
be able to operate depending on the surrounding environment.

NOTICE

●

The detection range of the sensors (



P. 445) is limited. Directly confirm

the safety of your surroundings, and if there is a possibility of a contact
accident, stop the vehicle by depressing the brake pedal.
