When driving
PRIUS_U (OM47668U) U.S.A.
CAUTION
●
Do not let the vehicle roll backwards while the shift lever is in a driving
position, or roll forward while the shift lever is in “R”. 
Doing so may cause the hybrid system not to operate or lead to poor
brake and steering performance, resulting in an accident or damage to th\
e
vehicle.
● If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by your Toyota dealer
immediately.
● 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 "D" while the vehicle is moving backward. 
Doing so can damage the transmission and may result in a loss of vehicle\

control.
● Moving 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.
● During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
but the power assist to these systems will be lost. This will make it more
difficult to steer and brake, so you should pull over and stop the vehicle as
soon as it is safe to do so. 
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 496
● Use engine braking (“B”) to maintain a safe speed when driving down a
steep hill. 
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 173)

NOTICE
■
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually press the brake pedal to slow down the vehicle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds.
● The vehicle will behave abnormally.
Replace a flat tire with a new one. ( P. 527)
■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle.
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following.
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
system, transmission, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble) and the function of all joints, bearings, etc.

Transmission
Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
You can operate the shift lever only in “D”.
Keep the shift lever in “N” for a while after you shift it to that
position.
The shift lever always returns to this original position after shifting operation.

PRIUS_U (OM47668U) U.S.A.
Changing shift ranges to “P” positionPush the “P” position switch with
the brake pedal pressed down.
The “P” position icon is displayed
on the instrument cluster, and the
indicator on the “P” position
switch comes on.
You can only shift to other posi-
tions from “P” when the brake
pedal is depressed.
When parking, check that the “P”
position icon is displayed on the
instrument cluster, and release
the brake pedal gently after
applying the parking brake.
ITO21P107
■Using engine brake
To use the engine braking, shift the shift lever to “B” position.
● During high speed driving, you may feel that deceleration by engine brak-
ing is less than that of a typical 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
normal driving.
