can be operated to select
whether you would like to park to
the left or right.
The system cannot be used
when the parking space is nar-
row or there is not a sufficient
enough area for assist control to
operate. Please refer to the infor-
mation shown on the multi-infor-
mation display to use a different
parking space.
2 Assume an ordinary driving pos-
ture, rest your hands lightly on
the steering wheel without
applying any force, directly con-
firm the safety of the area to the
front and around the vehicle and
slowly proceed forward while
adjusting your speed by
depressing the brake pedal.
When this is done, a
high-pitched beep is emitted
and an indicator on the meter
illuminates at the same time,
after which assist control will
start.
When the steering wheel auto
operation starts, the steering
wheel auto operation display and
assistance level indicator
( P.331) will be shown in the
display area.
To stop assist control, press the
S-IPA switch.
When the vehicle speed is too
high, a sharp beeping sound is
emitted and assist control is
stopped. ( P.332)
If the space turns out to be too
narrow after assist control starts,
a sharp beeping sound is emitted
and assist control is stopped.
3 When a level beep is emitted
and the stop display ( P.331) is
shown on the display, stop the
vehicle.
4 Change the shift lever to R.
5 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 the vehicle cannot be

sary, proceed to step 6.
When multi-turn maneuvering is
not necessary, proceed to step
12 .
6 When a level beep is emitted
and the stop display ( P.331) is
shown on the display, stop the
vehicle.
7 Change the shift lever to D or M.
When you would like to end assist con-
trol at your current position, change the
shift lever to P.
8 Assume an ordinary driving pos-
ture, rest your hands lightly on
the steering wheel without
applying any force, directly con-
firm the safety of the area to the
front and around the vehicle and
slowly proceed forward while
adjusting your speed by
depressing the brake pedal.
9 When a level beep is emitted
and the stop display ( P.331) is
shown on the display, stop the
vehicle.
10 Change the shift lever to R.
11 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 slowly back up while
adjusting your speed by
depressing the brake pedal.
Depending on the condition of the park-
ing space, steps 6 to 11 may need to
be repeated.
12 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 ( P.331),
stop the vehicle.
This completes the back-in parking
assist mode.
For safety, the buzzer sounds
slightly before the vehicle is com-
pletely entered within the target
parking spot. Furthermore, at
that point, system operation will
also finish. Firmly hold the steer-
ing 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 check-
ing the area to the front and rear
of the vehicle directly and by
using the mirrors.
■Back-in parking assist mode oper-
ating conditions
●In order to operate the function cor-
rectly, drive slowly (at a speed at which the vehicle can be quickly
stopped). Come to a full stop so that
the center of the parking space is nearly perpendicular to the vehicle,
and then operate the S-IPA switch.
●The function cannot be used when the
vehicle speed is approximately 30
km/h (19 mph) 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.353), guidance is not issued.
●If there are no parked vehicles, the parking spot cannot be determined.
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.
●Depending on the condition of the parking space, if there is not enough
space in front of the vehicle required
to perform the parking operation, the target parking spot may not be reach-
able.

■Tips for using the back-in parking assist mode
1 Leave a gap of approximately 1 m
(3.3 ft.) from any parked vehicles
and approach the target parking spot. If the gap between your vehicle
and any parked vehicles is too large,
the front side sensors and rear side sensors may not be able to detect
the parked vehicles.
1 m (3.3 ft.)
2 Stop so that the center of the target parking spot is perpendicular to the
vehicle. Furthermore, only push the
S-IPA switch when the vehicle is at a complete stop.

When the Simple Intelligent Parking Assist System cannot be operated, or
when operation is stopped, canceled, etc., the one of the following mes-
sage is displayed on the multi-information display. Take appropriate action
according to the display.
■When it is not possible to operate
NOTICE
■When using the back-in parking
assist mode
●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 park-
ing spot. In these cases, do not use
the back-in parking assist mode.
●When parking in a narrow space,
the vehicle will come close to adja-
cent vehicles. If it seems the vehicle may make contact, stop the vehicle
by depressing the brake pedal.
●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.
●Depending on the surrounding envi-
ronment, such as other parked vehicles, the vehicle may be parked
at an angle or may deviate from the
parking spot. Manually adjust vehi- cle alignment as necessary.
