When selecting a shift position, make sure that the shift position
has been changed to the desired position by checking the shift
position indicator provided on the instrument panel.
When a shift position other than D or B is selected, the arrow
toward B disappears from the shift position indicator.
Shift position purpose
*: For good fuel economy and noise reduction, the D position should usu-
ally be used.
Shift positionFunction
PParking the vehicle or starting the hybrid system
RReversing
NNeutral
DNormal driving*
BApplying moderate engine braking when driving
down hills or on steep slopes

Using engine braking
To use engine braking, select the B position.
During high speed driving, you may feel that deceleration by engine brak-
ing is less than that of a conventional vehicle.
Do not continue normal driving with the transmission in B for a long time.
This may cause decreased fuel economy. To prevent this, use D for nor-
mal driving.
Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift
lever is in R.
Eco drive mode
When the accelerator pedal is depressed in Eco drive mode, it may take
more time to accelerate than usual. This is normal operation.
Alarms
If the shift position is changed in any of the following situations, a buzzer will
sound and the shifting operation will be disabled or the shift position will
automatically change to N. When this happens, select an appropriate shift
position.
Situations where the shifting operation will be disabled:
• When the shift lever is changed from P to another position without
depressing the brake pedal.
• When the shift position is changed from P or N to B.
Situations where the shift position will automatically change to N:
• When the P position switch is pushed while the vehicle is moving.
• When shift position R is selected while the vehicle is moving forward.
• When shift position D is selected while the vehicle is moving in reverse.
• When the shift position is changed from R to B.

CAUTION
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.
Shift lever precautions
Do not hang anything on the shift lever.
Doing so could prevent the shift lever from returning to position, causing
unexpected accidents to occur when the vehicle is in motion.
NOTICE
Situations where P position control system malfunctions are possible
If any of the following situations occurs, P position control system malfunc-
tions are possible.
Immediately stop the vehicle in a safe place on level ground, apply the park-
ing brake, and then contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
When a warning message indicating malfunction appears on the multi-
information display. (P. 437)
When the P position switch indicator flashes.
When the shift position symbols (such as P and R) are flashing on the shift
position indicator.
When the shift position indicator remains off.
When in heavy traffic
If shift position N is selected, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid leaving the N
position selected for an extended period of time.

Hybrid System Indicator
Eco Driving Indicator Light
During Eco-friendly acceleration (Eco
driving), Eco Driving Indicator Light will
turn on.
Eco Driving Indicator Light will not oper-
ate in the following conditions:
• The shift position is anything other
than D.
• The driving mode is set to power
mode or EV-Drive Mode.
(P. 180, 186)
• The vehicle speed is approximately
130 km/h (80 mph) or higher.
Power area
Shows that the driving power is more
than the upper limit of Eco driving
(during full power driving etc.).
Eco area
Shows that the vehicle is driving in
Eco-friendly.
Hybrid Eco area
Shows that gasoline engine power is
not being used very often.
The gasoline engine will automatically
stop and restart under various condi-
tions.
Charge area
Shows regenerative charging.

By keeping the indicator needle within Eco area, more Eco-friendly driv-
ing can be achieved.
Charge area indicates regeneration* status. Regenerated energy will be
used to charge the battery.
Eco Driving Indicator Light can be enabled or disabled. (P. 203)
*: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.
NOTICE
To prevent damage to the hybrid system and its components
The hybrid system may be overheating if the top segments of the engine
coolant temperature gauge are flashing. In this case, immediately stop the
vehicle in a safe place, and check the hybrid system after it has cooled com-
pletely. (P. 481)

Sensor detection information
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 sensor will resolve
this problem.)
• The sensor is frozen. (Thawing the sensor will resolve this problem.)
• The sensor is covered in any way.
• In harsh sunlight or intense cold weather.
• When driving bumpy, sloped or gravel roads, or over grass.
• If there is something producing ultrasonic waves nearby, such as
another vehicle’s horn, motorcycle engine noise, air braking sound
from heavy-duty vehicles, or another vehicle using the park assist sys-
tem.
• In heavy rain, or if water is splashed on the sensors.
• The vehicle is leaning considerably to one side.
• If a commercial fender pole or radio antenna is installed.
• If moving towards a high curb or a curb corner.
• If towing eyelet is installed on your vehicle.
• The bumper or sensor receives a strong impact.
• A non-genuine Toyota suspension (lowered suspension etc.) is
installed.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensors to be
closer than they are.
The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles.
• Thin objects such as wire, fencing or rope.
• Objects that absorb sound waves, such as cotton or snow.
• Objects with sharp corners.
• Low objects.
• Objects where the upper section projects out over the lower section.

When the VSC/TRC systems are operating
If the vehicle is in danger of slip-
ping or the front wheels spin, the
indicator flashes to indicate that
the VSC/TRC systems have
been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed repeatedly, or 1 - 2 minutes after the hybrid system is
stopped. This sound does not indicate that a malfunction has occurred in
any of these systems.
Any of the following conditions may occur when the above systems are
operating. None of these indicate that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the hybrid system off.
The system should return to normal within 10 minutes.
