■Function summary
Stop so that the center of the target parking spot appears nearly
perpendicular to the vehicle. If t he space is detectable, the forward
guidance function can be used. Furthermore, depending on the
parking space and other condition s, multi-turn maneuvering assist
control is also provided if necessary.
Stop so that the center of the
target parking spot appears
nearly perpendicular to the
vehicle. Then press the
S-APGS switch 2 times to
select back-in parking assist
mode.
Steering wheel auto opera-
tion starts when the vehicle
begins to move.
A sound is issued and a dis-
play is shown to notify you
when the vehicle reaches the
position to start backing up
from.
If the detected parking space or
road width (distance to the side
of the road across from the park-
ing space) is narrow, or if there
are obstacles in front of the vehi-
cle, 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 backing up, as well as the steering wheel
auto operation, are repeated any time multi-turn maneuvering is neces-
sary following step from the time the vehicle begins backing up until
parking completes.

■Function summary
If a parking space can be detected, you will be guided forward until
you reach the assist c ontrol starting position, and then the parallel
parking assist mode can be used. Furthermore, depending on the
parking space and other condition s, 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 dis-
play 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 pro-
vided by the system, steering
wheel auto operation begins.
If the detected parking space or road width (distance to the side of th\
e
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.

The S-APGS switch is operated in an area with no
parking spaces, or operated in an area where the
road width for parking is narrow.
→Assist control cannot be used, as there is no
parking space. Proceed to a parking space
which width is approximately 8.5 ft. (2.6 m) or
larger.
→ Assist control cannot be used, as the road
width is narrow. Proceed to a parking space
where the road width is approximately 15 ft.
(4.5 m) or larger.
The S-APGS switch is operated at a space that is
too narrow for the vehicle to park in.
→Assist control cannot be used, as there is no
parking space. Proceed to a parking space
that is approximately 8.5 ft. (2.6 m) or larger.
The S-APGS switch is operated in an area where
there are obstacles to the front, and the vehicle can-
not move forward to the starting point for backing
up.
→Assist control cannot be used, as there are
obstacles in front of the vehicle. Use parking
spaces that have no obstacles in front of
them.
The S-APGS switch is operated when there is not
enough space to the front and rear of the vehicle
when departing from a parallel parking spot.
→ The vehicle cannot depa rt using assist con-
trol as there is not enough space to the front
and rear of the vehicle . Confirm the safety of
your surroundings before departing.
The S-APGS switch is operated in an area where
there are no obstacles to the front of the vehicle, or
there are obstacles to the sides and the vehicle can-
not depart from the parallel parking spot.
→ Assist control cannot be used for departure,
as there are obstacles to the sides of the vehi-
cle or departure can easily be performed man-
ually. Confirm the safety of your surroundings
before departing.

■Screen description
The rear view monitor system scr een will be displayed if the shift
lever is shifted to R while the power switch is in ON mode.
Vehicle width extension guide line
Displays a guide path when the vehicle is being backed straight up.
The displayed width is wider than the actual vehicle width.
Vehicle center guide line
This line indicates the estimated vehicle center on the ground.
Distance guide line
Displays a point approximately 1.5 ft. (0.5 m) (red) from the edge of the
bumper.
Distance guide line
Displays a point approximately 3 ft. (1 m) (blue) from the edge of the
bumper.

■Rear view monitor system camera
The camera for the rear view
monitor system is located as
shown in the illustration.
● Using the camera
If dirt or foreign matter (such as water droplets, snow, mud etc.)
is adhering to the camera, it cannot transmit a clear image. In
this case, flush it with a large quantity of water and wipe the cam-
era lens clean with a soft and wet cloth.
■Differences between the screen and the actual road
The distance guide lines and the v ehicle width guide lines may not
actually be parallel with the dividi ng lines of the parking space, even
when they appear to be so. Be sure to check visually.
The distances between the vehicle width guide lines and the left
and right dividing lines of the parking space may not be equal, even
when they appear to be so. Be sure to check visually.
The distance guide lines give a distance guide for flat road sur-
faces. In any of the following situations, there is a margin of error
between the fixed guide lines on the screen and the actual dis-
tance/course on the road.

●When any part of the vehicle sags
When any part of the vehicle
sags due to the number of
passengers or the distribu-
tion of the load, there is a
margin of error between the
fixed guide lines on the
screen and the actual dis-
tance/course on the road.
■When approaching thre e-dimensional objects
The distance guide lines are displayed according to flat surfaced
objects (such as the road). It is not possible to determine the posi-
tion of three-dimensional objects (s uch as vehicles) using the vehi-
cle width guide lines and distance guide lines. When approaching a
three-dimensional object that extends outward (such as the flatbed
of a truck), be careful of the following.
● Vehicle width guide lines
Visually check the surround-
ings and the area behind the
vehicle. In the case shown
below, the truck appears to
be outside of the vehicle
width guide lines and the
vehicle does not look as if it
hits the truck. However, the
rear body of the truck may
actually cross over the vehi-
cle width guide lines. In real-
ity if you back up as guided
by the vehicle width guide
lines, the vehicle may hit the
truck.

Maintenance and care
Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance we ights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.
