When driving
PRIUS_U (OM47668U) U.S.A.
CAUTION
■
When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, you may accidentally move the
shift lever or depress the accelerator pedal, which could cause an accident
or fire due to hybrid system overheating. Additionally, if the vehicle is parked
in a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
■ When braking the vehicle
● When the brakes are wet, drive more cautiously. 
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other
vehicles closely and avoid downhill or sharp turns that require braking. 
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
● The brake system consists of 3 individual hydraulic systems: if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and braking distance
becomes longer. 
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.

■No-handed driving warning
If the steering wheel is not operated for about 15 seconds on a straight road
or about 5 seconds on a curve, the buzzer will beep twice, indicators on the
multi-information display will flash, and the lane keeping assist function will
be temporarily canceled. If you drive the vehicle with your hands lightly
touching the steering wheel, this may also be detected as no-handed driv-
ing.
■ When the vehicle has been parked in the sun
The LKA system functions may not be available for a while after driving has
started. In such cases, turn the LKA system off and turn it on again after nor-
mal temperature returns. When the temperature in the cabin decreases and
the temperature around the camera sensor becomes suitable for its opera-
tion, the functions will begin to operate.
CAUTION
■Before using the LKA system
Do not rely on the LKA system to remain within a selected lane. The LKA
system is not designed to enable inattentive driving. The steering wheel
should be operated by the driver to mainta in the vehicle in a suitable position
within its lane. Always drive carefully.

Hill-start assist control
■Hill-start assist control operating conditions
The system operates in the following situations:
• The shift position is in other than “P”.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
■ Hill-start assist control
● While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
● Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
● If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicl e to roll backward) and then firmly
depress it again. If the system still does not operate, check that the oper-
ating conditions explained above have been met.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

■Hill-start assist control buzzer
● When hill-start assist control is activated, the buzzer will sound once.
● In the following situations, hill-start assist control will be canceled and the
buzzer will sound twice.
• No attempt is made to drive the vehicle within approximately 2 seconds
of releasing the brake pedal.
• The “P” position switch is pressed.
• The parking brake is applied.
• The brake pedal is depressed again.
■ If the slip indicator comes on...
It may indicate a malfunction in the system. Contact your Toyota dealer.
CAUTION
■Hill-start assist control
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on extremely st eep inclines or roads covered in ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline for an extended
period of time, as doing so may lead to an accident.

PRIUS_U (OM47668U) U.S.A.Towing eyelet
ITO51P107
■
Emergency towing procedure
Release the parking brake.
Turn the “POWER” switch to ON mode.
Put the shift lever in “N”.
CAUTION
■While towing
● Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelet and the cable or chain.
● If the hybrid system is not operating, the power assist for the brakes and
steering will not function, making steering and braking more difficult.
NOTICE
■To prevent causing serious dama ge to the transmission
Never tow this vehicle from the rear with the four wheels on the ground. 
This may cause serious damage to the transmission.

CAUTION
■When the spare tire is attached
The vehicle speed may not be correctly detected, and the following sys-
tems may not operate correctly:
●ABS & Brake assist
●Enhanced VSC
●Navigation system (if equipped)
●TRAC
●Dynamic radar cruise control (if equipped)
●Cruise control (if equipped)
●PCS (if equipped)
●LKA (if equipped)
●Rear view monitor system (if equipped)
●Advanced parking guidance system (if equipped)
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their
storage location to reduce the possibility of personal injury during a collision
or sudden braking.
■ When stowing the flat tire
● Make sure the rear seats are in their original position.
● Secure it using a tire tie-down belt. Otherwise, the flat tire may fly out in
case of the sudden braking or an accident, resulting in death or serious
injury.
