■When driving with dynamic radar cruise control with full-speed range
activated
Even when performing the following actions with the intent of e nabling engine
braking, engine braking will not occur because radar cruise con trol with full
speed range will not be canceled.
● While driving in D or S mode, downshifting to 5 or 4. (
P. 276)
● When switching the driving mode to sport mode while driving in the D posi-
tion. (
P. 340)
■ Restraining sudden start (Drive-start Control)
P. 198
■ Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the power switc h is in the ON
mode, the brake pedal is depressed and the shift release button is pushed.
■ If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted even though the brake peda l is depressed
and the shift release button is pushed, there may be a problem with the shift
lock system. Have the vehicle inspected by your Toyota dealer i mmediately.
The following steps may be used as an emergency measure to ensu re that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the power switch off.
Depress the brake pedal.
Pry the cover up with a flathead screw-
driver or equivalent tool.
To prevent damage to the cover, cover
the tip of the screwdriver with a rag.
Press and hold the shift lock override
button and then push the button on the
shift knob.
The shift lever can be shifted while both
buttons are pressed.

2244-2. Driving procedures
■If the S indicator does not come on or the D indicator is displayed even
after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission s ystem. Have
the vehicle inspected by your Toyota dealer immediately.
(In this situation, the transmission will operate in the same m anner as when
the shift lever is in D.)
WARNING
■ When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to se t the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of t he brake pedal
when the shift lock override button is pressed and the shift le ver is shifted
out of P, the vehicle may suddenly start, possibly leading to a n accident
resulting in death or serious injury.
NOTICE
■ Hybrid battery (traction battery) charge precaution
If the shift lever is in N, the hybrid battery (traction batter y) will not be
charged even when the engine is running. Therefore, if the vehi cle is left
with the shift lever in N for a long period of time, the hybrid battery (traction
battery) will discharge, and this may result in the vehicle not being able to
start.

■Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC,
and hill-start assist control systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the hybrid system is started or just after the
vehicle begins to move. This sound does not indicate that a mal function has
occurred in any of these systems.
● Any of the following conditions may occur when the above system s are
operating. None of these indicates that a malfunction has occur red.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a s top.
■ ECB operating sound
ECB operating sound may be heard in the following cases, but it does not
indicate that a malfunction has occurred.
● Operating sound heard from engine compartment when the brake pe dal is
operated.
● Motor sound of the brake system heard from the front part of th e vehicle
when the driver’s door is opened.
● Operating sound heard from the engine compartment when one or t wo min-
utes passed after the stop of the hybrid system.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) may be
heard. This does not indicate a malfunction.

WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctl y detect an obstacle. 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 ma y show an
abnormal display, or obstacles may not be detected.
● The sensor is covered in any way.
● The vehicle is leaning considerably to one side.
● On an extremely bumpy road, on an incline, on gravel, or on gra ss.
● 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.
● There is another vehicle equipped with parking assist sensors i n the vicin-
ity.
● The sensor is coated with a sheet of spray or heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is equipped with a fender pole or wireless antenna.
● Towing eyelets are installed.
● The bumper or sensor receives a strong impact.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● In harsh sunlight or intense cold weather.
● The area directly under the bumpers is not detected.
● If obstacles draw too close to the sensor.
● A non-genuine Toyota suspension (lowered suspension, etc.) is i nstalled.
● A backlit license plate is installed.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

■Situations in which the Intellige nt Clearance Sonar function ma y operate
even if there is no possibility of a collision
In some situations such as the following, the Intelligent Clear ance Sonar
function may operate even though there is no possibility of a c ollision.
● Vehicle surroundings
• When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parki ng lots).
• When driving on a narrow path surrounded by a structure, such as in a
tunnel or on an iron bridge
• When parallel parking
• When there is a rut or hole in the surface of the road
• When driving on a metal cover (grating), such as those used fo r drainage
ditches
• When driving on a steep slope
• If a sensor is hit by a large amount of water, such as when driving on a flooded road
● Weather
• If a sensor is covered with ice, snow, dirt, etc. (when cleared, the system
will return to normal)
• If heavy rain or water strikes a sensor
• When driving in inclement weather such as fog, snow or a sands torm
● Other ultrasonic waves sources
• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices
which produce ultrasonic waves are near the vehicle
• If a sticker or an electronic component, such as a backlit license plate (especially fluorescent type), fog lights, a fender pole or wir eless antenna
is installed near a sensor
• When driving on a narrow road
• When driving on a gravel road or in
an area with tall grass

3304-5. Using the driving support systems
●Other ultrasonic waves sources
• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices
which produce ultrasonic waves are near the vehicle
• If a sticker or an electronic component, such as a backlit license plate
(especially fluorescent type), fog lights, a fender pole or wir eless antenna
is installed near a sensor
● Changes in the vehicle posture
• If the vehicle is significantly tilted
• If the front of the vehicle is raised or lowered due to the ca rried load
• If the orientation of a sensor has been changed due to a collision or other impact
■ If a 12-volt battery terminal has been disconnected and reconne cted
The system needs to be initialized.
To initialize the system, drive the vehicle straight ahead for 5 seconds or more
at a speed of approximately 22 mph (35 km/h) or more.
■ If “ICS Unavailable” is displayed on the multi-information display and
the ICS OFF indicator is flashing
● A sensor may be covered with ice, snow, dirt, etc. Remove the ice, snow,
dirt, etc., from the sensor to return the system to normal.
Also, due to ice forming on a sensor at low temperatures, a war ning mes-
sage may be displayed or the sensor may not be able to detect an object.
Once the ice melts, the system will return to normal.
● If this message continues to be displayed even after cleaning the sensor, or
is displayed even though the sensor is clean, have the vehicle inspected by
your Toyota dealer.
● Initialization may not have been performed after a 12-volt batt ery terminal
was disconnected and reconnected. Initialize the system. (P. 330)

3424-6. Driving tips
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/coo ling) will be minimized, improving
the fuel economy. ( P. 340)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the needle of H ybrid
System Indicator within Eco area. ( P. 104)
◆Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift lever to P when parking. When using
the N, there is no positive effe ct on fuel consumption. In the N, the
gasoline engine operates but e lectricity cannot be generated. A lso,
when using the air conditioning s ystem, etc., the hybrid battery
(traction battery) power is consumed.
◆Accelerator pedal/brake pedal operation
● Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerat ion and deceleration will make
more effective use of the electric motor (traction motor) witho ut
having to use gaso line engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (tracti on battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
Hybrid vehicle driving tips
For economical and ecological dri ving, pay attention to the fol-
lowing points:

Driving
◆When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits a t
traffic lights, will lead to bad fuel economy. Check traffic re ports
before leaving and avoid delays as much as possible. When drivi ng
in a traffic jam, gently release the brake pedal to allow the v ehicle to
move forward slightly while avoid ing overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.
◆Highway driving
Control and maintain the vehicle at a constant speed. Before st op-
ping at a toll booth or similar, allow plenty of time to releas e the
accelerator and gently apply the brakes. A greater amount of el ec-
trical energy can be regenerated when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient tempe rature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system and reduce fuel consumption as well.
In winter: Because the gasolin e engine will not automatically cut out
until it and the interior of the vehicle are warm, it will cons ume fuel.
Also, fuel consumption can be improved by avoiding overuse of t he
heater.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Impr oper
tire inflation pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to poor fuel economy. Use tires that are app ro-
priate for the season.
