■Function summary
If a parking space can be detected, you will be guided forward until
you reach the assist control star ting position, and then the parallel
parking assist mode can be us ed. Furthermore, depending on the
parking space and other conditions, multi-turn maneuvering assi st
control is also prov ided 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 wher e 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 oper ation begins.
If the detected parking space or road width (distance to the si de 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 t he
parking space, guidance to starting points for moving forward and back-
ing up, as well as the steering wheel auto operation, are repea ted any
time multi-turn maneuvering is necessary following step from the
time the vehicle begins backing up until parking completes.

■Function summary
Stop so that the center of the target parking spot appears near ly
perpendicular to the vehicle. If the space is detectable, the f orward
guidance function can be used. Furthermore, depending on the
parking space and other conditions, multi-turn maneuvering assi st
control is also prov ided 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-

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 st arting
points for moving forward and backing up, as well as the steeri ng wheel
auto operation, are repeated any time multi-turn maneuvering is neces-

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.
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.

This information has been prepared in accordance with regulations
issued by the National Highway Tr affic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with info rmation on uniform ti re quality grading.
Your Toyota dealer will help answer any questions you may have as
you read this information.
■DOT quality grades
All passenger vehicle tires must conform to Federal Safety Requ ire-
ments in addition to these grades. Quality grades can be found
where applicable on the tire sidewall between tread shoulder an d
maximum section width.
For example: Treadwear 200 Traction AA Temperature A
■Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a s peci-
fied government t est course.
For example, a tire graded 150 would wear one and a half (1 - 1 /2)
times as well on the governmen t course as a tire graded 100.
The relative performance of tires depends upon the actual condi -
tions of their use. Performance ma y differ significantly from the norm
due to variations in driving habits, service practices and diff erences
in road characteristics and climate.
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C ,
and they represent the tire’s ability to stop on wet pavement a s
measured under controlled conditions on specified government te st
surfaces of asphalt and concrete.
A tire marked C may have p oor traction performance.
Warning: The traction grade assigned to this tire is based on b raking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
