Shifting the shift position from P to other positions
● While depressing the brake pedal f irmly, operate the shift lever. I f
the shift lever is operated withou t depressing the brake pedal, the
buzzer will sound and the shifting operation will be disabled.
● When selecting the shift position, make sure that the shift pos i-
tion has been changed to the desired position by checking the
shift position indica tor provided on the in strument cluster.
● The shift position cannot be changed from P to B directly.

■Daytime running light system
●The daytime running lights illuminate using the same lights as the head-
lights, and illuminate dimmer than the headlights.
● To make your vehicle more visible to other drivers during dayti me driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designe d for use at
night.)
• The hybrid system is operating
• The parking brake is released
• The headlight switch is in the (Canada only), , or
* position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, eve n if the park-
ing brake is set again.
● For the U.S.A.: Daytime running lights can be turned off by ope rating the
switch.
● Compared to turning on the headlights, the daytime running ligh t system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor (if equipped)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
Air conditioning operation may also be
interrupted.

■Dynamic radar cruise control wi th full-speed range can be set when
● The shift position is in D.
● Vehicle speed is at or above approximately 30 mph (50 km/h).
However, when a preceding vehicle is detected, the dynamic rada r cruise
control with full-speed range can be set even if the vehicle speed is at or
below approximately 30 mph (50 km/h).
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicl e distance
control mode, the vehicle speed may decrease below the set spee d in order
to maintain the distance to the preceding vehicle.
■ When the vehicle stops while follow-up cruising
●Pushing the lever up while the vehicle ahead stops will resume follow-up
cruising if the vehicle ahead starts off within approximately 3 seconds after
the lever is pushed up.
● If the vehicle ahead starts off within 3 seconds after your veh icle stops, fol-
low-up cruising will be resumed.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically cance led in the fol-
lowing situations:
● Actual vehicle speed falls at or below approximately 25 mph (40 km/h) when
there are no vehicles ahead.
● The preceding vehicle leaves the lane when your vehicle is following at a
vehicle speed at or below approximately 25 mph (40 km/h). Other wise, the
sensor can not properly detect the vehicle.
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● The sensor cannot detect correctly because it is covered in some way.
● Pre-collision braking is activated.
● Intelligent Clearance Sonar is operated. (if equipped)
● The parking brake is operated.
● The vehicle is stopped by system control on a steep incline.
● The following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes.
In this situation, the shift position may automatically switch to P. (P. 341)
If vehicle-to-vehicle distance control mode is automatically ca nceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

■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 case s, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a mal function dis-
play may appear or an obstacle may not be detected. If the sens or thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction” is displayed 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. 739)
WARNING
■When using intuitive parking assist
Observe the following precautions to avoid an unexpected accident.
● Do not exceed the speed limit of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle ( especially
the sides of the vehicle) for safety, and drive slowly, using t he brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.

WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen, the screen m ay show an
abnormal display, or obstacles may not be detected.
● The sensor is covered in any way.
● In harsh sunlight or intense cold weather
● On an extremely bumpy road, on an incline, on gravel, or on grass
● The vicinity of the vehicle is noisy due to vehicle horns, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● The sensor is splashed with water or drenched with heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is leaning considerably to one side.
● The vehicle is equipped with a fender pole or wireless antenna.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● The area directly under the bumpers is not detected.
● If obstacles draw too close to the sensor.
● The bumper or sensor receives a strong impact.
● A non-genuine Toyota suspension (lowered suspension etc.) is in stalled.
● There is another vehicle equipped with parking assist sensors i n the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate is installed.
In addition to the examples above, depending on the shape and c ondition of
obstacles, detection may not be possible, or the detection rang e may be
shortened.

Intelligent Clearance Sonar
The system operates in the follo wing situations when an obstacle is
detected in the traveling d irection of the vehicle.
◆The vehicle is driven at low speeds and the brake pedal is not
depressed, or is depressed too late
◆The accelerator pedal is depressed too far
: If equipped
When a collision may occur with an obstacle while parking or
traveling at low speeds, when the vehicle suddenly moves for-
ward due to mistaken accelerator pedal operation, or when the
vehicle moves due to the wrong shift position being selected,
the sensors detect obstacles to the front or rear in the travel ing
direction of the vehicle, and the system operates to lessen
impact with obstacles such as walls, and reduce resulting dam-
age.
