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.

■
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. 500), 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.

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.

Tips for using the back-in parking assist mode
●
Depending on the condition of the park-
ing 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 reachable.
Intended parking spot
Wall
●
Leave a gap of approximately 3.3 ft. (1
m) 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 vehi-
cles.
●
Stop so that the center of the target
parking spot is perpendicular to the vehi-
cle. Furthermore, only push the S-APGS
switch when the vehicle is at a complete
stop.
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 back-in park-
ing assist mode.
●
When parking in a narrow space, the vehicle will come close to adjacent
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 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.

Heating
●
In HV mode, the gasoline engine may operate in order to extract heat from
the engine coolant via the heater.
●
In EV mode, heating is done by a heat pump system.
• When the outside temperature is low or it is snowing, compared to con-
ventional vehicles, heating may be less effective and warm air may not
come out.
• If frost has formed on the outside heat exchanger, the heating perfor-
mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Air Conditioning System before driv-
ing (
P. 535). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When
is turned on, the heating is controlled optimally. Therefore,
the set heating performance may not be achieved even if the fan speed
setting is increased.
●
In the following situations the gasoline engine may operate in order to
extract heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approximately 14°F (-10°C) or low
•
is operating
■
Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after
is pressed.
■
Water droplets during air conditioning operation
• When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte-
rior. However, it is not a malfunction.
In this situation, the air temperature
from the outlets may not change even
though the set temperature is raised.
The outside heat exchanger, accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, it is not a malfunction.
