4-5. Using the driving support systems
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal will resume fol-
low-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

■Obstacle warning function
■ Obstacle detection in side areas
●Obstacles in the side areas are detected while driving by scanning the side
areas with the side sensors. Recognized obstacles are retained in memory
for up to approximately 2 minutes.
● Obstacles may not be detected in the side areas until the scan completes.
After the power switch is turned on, scanning completes after driving the
vehicle for a short period of time.
● When an obstacle such as another vehicle, pedestrian or animal is detected
by the side sensors, the obstacle may continue to be detected even after it
has left the side sensor detection area.
■ If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction” is di splayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: →P. 748)
When an obstacle in the side areas is
within the vehicle course while the vehicle
is moving forward or backward, this func-
tion inform the driver by the display and
the buzzer.

■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.

4-5. Using the driving support systems
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 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. 391), 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.
