PRIUS PHV_OM_OM47C99E_(EE)■Restraining 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. 686)
■“ECO Accelerator Guidance” (P. 232)
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. 520) 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.

3605-2. Driving procedures
PRIUS PHV_OM_OM47C99E_(EE)■Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift
position is in R.
■Restraining sudden start (Drive-Start Control)
P. 338
■Automatic P position selection function
●If the power switch is on and the shift position is not already P, completely
stopping the vehicle and pressing the power switch causes the shift position
to automatically switch to P and the power switch to turn off
*.
●The shift position may also automatically switch to P if one of the following
conditions is detected while the vehicle is stopped by dynamic radar cruise
control with full-speed range.
• Driver’s seat belt is not fastened
• Driver’s door is opened
• Approximately 3 minutes elapse after the vehicle stopped
*: If the power switch is pressed when driving at very low speeds (for exam-
ple, just before the vehicle stops), the shift position may automatically
switch to P. Press the power switch after completely stopping the vehicle to
prevent unexpected sudden stopping of the vehicle.
■If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. (P. 712)
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
●When the vehicle is driven at high speeds, compared to ordinary gasoline-
fueled vehicles, the engine braking deceleration is felt less than that of other
vehicles.
●The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, select the D position.
■After recharging/reconnecting the 12-volt battery

The Toyota Safety Sense consists of the following drive assist
systems and contributes to a safe and comfortable driving expe-
rience:
WARNING
■ Toyota Safety Sense
The Toyota Safety Sense is designed to operate under the assumption that
the driver will drive safely, and is designed to help reduce the impact to the
occupants and the vehicle in the case of a collision or assist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’s surround-
ings and driving safely.

PRIUS PHV_OM_OM47C99E_(EE)
Dynamic radar cruise controlwith full-speed
range
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates, decelerates and stops to match the speed changes of the
preceding vehicle even if the accelerator pedal is not depressed. In
constant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on free-
ways and highways.

WARNING
■Before using dynamic radar cruise control with full-speed range
Driving safely is the sole responsibility of the driver. Do not rely solely on the
system, and drive safely by always paying careful attention to your sur-
roundings.
The dynamic radar cruise control wi th full-speed range provides driving
assistance to reduce the driver’s burden. However, there are limitations to
the assistance provided.
Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, t he driver must always remain alert,
assess the danger of each situation and drive safely. Relying solely on this
system or assuming the system ensures safety while driving can lead to an
accident, resulting in death or serious injury.
■ Cautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or serious injury.
● Assisting the driver to measure following distance
The dynamic radar cruise control with full-speed range is only intended to
help the driver in determining the fo llowing distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mecha-
nism that allows careless or inattentive driving, and it is not a system that
can assist the driver in low-visibility conditions. It is still necessary for
driver to pay close attention to the vehicle’s surroundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control with full-speed range determines
whether the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead is within a set range. It is not capable
of making any other type of judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigila nt and to determine whether or not there
is a possibility of danger in any given situation.
● Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range does not include
functions which will prevent or avoid collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any possibility of danger, the driver must
take immediate and direct control of the vehicle and act appropriately in
order to ensure the safety of all involved.

WARNING
■To avoid inadvertent dynamic radar cruise control with full-speed
range activation
Switch the dynamic radar cruise control with full-speed range setting to off
using the “ON-OFF” button when not in use.
■ Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclers, etc.
● In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
● At entrances to freeways and highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● During emergency towing
● When an approach warning buzzer is heard often
