WARNING
■When folding the rear seatbacks down
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Do not fold the seatbacks down while driving.
● Stop the vehicle on level ground, set the parking brake and shi ft the shift
lever to P.
● Do not allow anyone to sit on a folded seatback or in the lugga ge compart-
ment while driving.
● Do not allow children to enter the luggage compartment.
● For vehicles with split rear seats, do not allow anyone sit on the rear center
seat if the rear right seat is folded down, as the seat belt bu ckle for the rear
center seat belt is then concealed under the folded seat and ca nnot be
used.
● Be careful not to catch your hand when folding the rear seatbac ks.
● If it is necessary to detach the head restraints, remove it from the vehicle
or store it securely in the luggage compartment. This will prev ent it from
injuring passengers in the event of sudden braking, sudden swer ving or an
accident.
● Adjust the position of the front seat before folding down the rear seatbacks
so that the front seat does not interfere with the rear seatbacks when fold-
ing down the rear seatbacks.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is stopped
● Do not depress the accelerator pedal unnecessarily.
If the shift lever is in any position other than P or N, the vehicle may accel-
erate suddenly and unexpectedly, causing an accident.
● Do not leave the vehicle with the hybrid system on for a long t ime.
If such a situation cannot be avoided, park the vehicle in an o pen space
and check that exhaust fumes do not enter the vehicle interior.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indic ator is
illuminated, and apply the parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent ac cidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped m ay cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this 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
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this ma y cause
one side of the vehicle to brake differently than the other sid e. Also, the
parking brake may not securely hold the vehicle.
● If the electronically controlled brake system does not operate, do not fol-
low other vehicles closely and avoid hills or sharp turns that require brak-
ing.
In this case, braking is still possible, but the brake pedal sh ould be
depressed more firmly than usual. Also, the braking distance wi ll increase.
Have your brakes fixed immediately.
● The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In t his case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.
NOTICE
■ When driving the vehicle
● Do not depress the accelerator and brake pedals at the same tim e during
driving, as this may restrain the hybrid system output.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always set the parking brake, and shift the shift lever to P. F ailure to do so
may cause the vehicle to move or the vehicle may accelerate sud denly if
the accelerator pedal is accidentally depressed.

As shown in the example above, if the number of occupants
increases, the cargo and luggage load will be reduced by an amount
that equals the increased weight due to the additional occupant s. In
other words, if an increase in the number of occupants causes a n
excess of the total load capacity (combined weight of occupants plus
cargo and luggage load), you must reduce the cargo and luggage on
your vehicle.
WARNING
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-
ment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed pr operly,
may block the driver’s vision, or may result in items hitting t he driver or
passengers, possibly causing an accident.
●Stow cargo and luggage in the luggage compartment whenever poss i-
ble.
●Do not stack cargo and luggage in the luggage compartment highe r
than the seatbacks.
●Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or rea r seats (when stacking items)
• On the luggage cover (if equipped)
• On the instrument panel
• On the dashboard
●Secure all items in the occupant compartment.
●When you fold down the rear seats, long items should not be pla ced
directly behind the front seats.
●Never allow anyone to ride in the luggage compartment. It is no t
designed for passengers. They should ride in their seats with t heir seat
belts properly fastened.

●The immobilizer system may not have been deactivated. ( P. 88)
Contact your Toyota dealer.
■ Steering lock
After turning the power switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
power switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system . After about 10
seconds, the steering lock motor will resume functioning. ● Check that the shift lever is securely set
in P. The hybrid system may not start if
the shift lever is not securely in the P
position. “SHIFT INTO P POSITION TO
START” will be displayed on the multi-
information display.
“STEERING LOCK ACTIVE” will be dis-
played on the multi-information display.
Check that the shift lever is set in P.

2224-4. Refueling
PRIUS c_U
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, tou ch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks re sulting from
static electricity can cause fuel vapors to ignite while refuel ing.
● Always hold the grips on the fuel tank cap and turn it slowly t o remove it.
A whooshing sound may be heard when the fuel tank cap is loosen ed.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a p ossible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing f rom the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically click s off.
● Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission c ontrol
system to operate abnormally or damaging fuel system components or the
vehicle's painted surface.
