■When the ambient temperature is low, such as during winter driving con-
ditions
● When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indicator is steady
on, as steady means the vehicle is able to move.
● When the hybrid battery (traction battery) is extremely cold (below approxi-
mately -22°F [-30°C]) under the influence of the outside temperature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to
the outside temperature increase etc.

■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically whenever the hybrid system
is started and the parking brake is released with the headlight switch in the
/ / position. (Illuminate dimmer than the headlight lights.)
Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor (if equipped)
■ Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the power switch is turned to
ACCESSORY mode or turned off. (The lights turn off immediately if on
the key is pressed after all the doors are locked.)
● When only the tail lights come on: The tail lights turn off automatically if the
power switch is turned to ACCESSORY mode or turned off and the driver’s
door is opened.
To turn the lights on again, turn the power switch to ON mode, or turn th\
e light
switch off once and then back to or . 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 with full-speed range can be set when
● The shift position is in D.
● Vehicle speed is above approximately 30 mph (50 km/h).
However, when a preceding vehicle is detected, the dynamic radar 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-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■ Automatic cancelation of vehicle-t o-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations.
● Actual vehicle speed falls 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 below approximately 25 m ph (40 km/h). Otherwise, the sen-
sor 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 by pressing the VSC OFF
switch.
● The sensor cannot detect correctly because it is covered in some way.
● Pre-collision braking is activated.
● The parking brake is operated.
● Intelligent Clearance Sonar is operated. (if equipped)
● 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. 237)
If vehicle-to-vehicle distance control mode is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

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 will resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen, the screen may 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, motorcycle
engines, air brakes of large vehicles, or other loud noises producing 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 installed.
● There is another vehicle equipped with parking assist sensors in the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate is installed.
In addition to the examples above, depending on the shape and condition of
obstacles, detection may not be possible, or the detection range may be
shortened.

Intelligent Clearance Sonar∗
The system operates in the following situations when an obstacle is
detected in the traveling direction 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 traveling
direction of the vehicle, and the system operates to lessen
impact with obstacles such as walls, and reduce resulting dam-
age.
