Operation of each component
■ When “Smart Entry & Start System Malfunction See Owner’s Manual” is
displayed on the multi-information display
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer
immediately.
■ Battery-saving function
The battery-saving function will be activated in order to prevent the electronic
key battery and the 12-volt battery from being discharged while the vehicle is
not in operation for a long time.
● In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.) of
the outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.
● If the smart entry & start system has not been used for 14 days or longer,
the doors cannot be unlocked at any doors except the driver’s door. In this
case, take hold of the driver’s door handle, or use the wireless remote con-
trol or the mechanical key, to unlock the doors.
■ Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.
Press twice while pressing and
holding . Confirm that the electronic
key indicator flashes 4 times.
While the battery-saving mode is set, the
smart entry & start system cannot be
used. To cancel the function, press any of
the electronic key buttons.

■Restraining the hybrid system output (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the
hybrid system output may be restrained.
●A warning message is displayed on the multi-information display while the
system is operating. (P. 729)
■“ECO Accelerator Guidance” (P. 239)
It is easier to drive in an Eco-friendly manner by driving while referring to the
“ECO Accelerator Guidance” display. Also, by using the “ECO Accelerator
Guidance”, it is easier to increase the Eco score evaluation.
●When starting off:
While staying within the “ECO Accelerator Guidance” range, gradually
depress the accelerator pedal and accelerate to the desired speed. If exces-
sive acceleration is avoided, the “Eco-Start” score will increase.
●When driving:
After accelerating to the desired speed, release the accelerator pedal and
drive at a stable speed within the “ECO Accelerator Guidance” range. By
keeping the vehicle within the “ECO Accelerator Guidance” range, the “Eco-
Cruise” score will increase.
●When stopping:
When stopping the vehicle, early releasing the accelerator pedal will cause
the “Eco-Stop” score to increase.
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is performed, the hybrid system out-
put may be restrained.
• When the shift position is shifted from R to D/B, D/B to R, N to R, P to D/
B
*, P to R* with the accelerator pedal depressed, a warning message
appears on the multi-information display. If a warning message is shown
on the multi-information display, read the message and follow the instruc-
tions.
• When the accelerator pedal is depressed too much while the vehicle is in
reverse.
●While Drive-Start Control is being activated, your vehicle may have trou-
ble escaping from the mud or fresh snow. In such case, deactivate TRC
(P. 561) to cancel Drive Start Control so that the vehicle may become
able to escape from the mud or fresh snow.
*: Depending on the situation, the shift position may not be changed.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When shifting the shift position
● Do not let the vehicle roll backward while a forward driving position is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
● Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift position to a driving position while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Changing the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hybrid system
disengaged.
● Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any position other than P or N may lead to
unexpected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
After changing the shift position, make sure to confirm the current shift
position displayed on the shift position indicator inside the meter.

Driving
Modes can be changed by pressing the power switch with the brake
pedal released. (The mode changes each time the switch is pressed.)
Off
The emergency flashers can be
used.
ACCESSORY mode
Some electrical components such
as the audio system can be used.
“Accessory” is displayed on the
main display.
ON mode
All electrical components can be
used.
“Ignition ON” is displayed on the
main display.
■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON
mode (the hybrid system is not operating) for more than an hour with the shift
position in P, the power switch will automatically turn off. However, this func-
tion cannot entirely prevent the 12-volt battery discharge. Do not leave the
vehicle with the power switch in ACCESSORY or ON mode for long periods
of time when the hybrid system is not operating.
■Sounds and vibrations specific to a hybrid vehicle
P. 106
■Electronic key battery depletion
P. 280
■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 -30C [-22F]) 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.
