CAUTION
When installing a child restraint system
If other second seats interfere with the child restraint system when install-
ing a child restraint system in the second seat, adjust the seat cushions to
the same position and align the seatbacks at the same angle. Otherwise,
the child restraint system cannot be securely restrained and this may
cause death or serious injuries in the event of sudden braking, sudden
swerving or an accident.
When a junior seat is installed, always ensure that the shoulder belt is
positioned across the center of the child’s shoulder. The belt should be
kept away from the child’s neck, but not so that it could fall off the child’s
shoulder. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
Ensure that the belt and plate are securely locked and the seat belt is not
twisted.
Shake the child restraint system left and right, and forward and backward
to ensure that it has been securely installed.
After securing a child restraint system, never adjust the seat.
Follow all installation instructions provided by the child restraint system
manufacturer.
To correctly attach a child restraint system to the anchors
When using the ISOFIX rigid anchors, be sure that there are no foreign
objects around the anchors and that the seat belt is not caught behind the
child restraint system. Make sure the child restraint system is securely
attached, or it may cause death or serious injury to the child or other passen-
gers in the event of a sudden stop, sudden swerve or accident.

208 2-1. Driving procedures
PRIUS +_OM_OM47821E_(EE)
CAUTION
If you hear a squealing or scraping noise (brake pad wear indicators)
Have any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional check and replace the brake pads as soon as possi-
ble.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
When the vehicle is stopped
Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any shift position other than P or N, the vehicle may
accelerate suddenly and unexpectedly, causing an accident.
Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open 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 the “READY” indicator is on. Apply the
parking brake as necessary.
If the vehicle is stopped on an incline, in order to prevent accidents 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 may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

When driving
PRIUS +_OM_OM47821E_(EE)
CAUTION
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 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 electronically controlled assist function does not operate, do not fol-
low other vehicles closely and avoid downhill or sharp turns that require
braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the others will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. If this happens, do not continue to drive the vehicle. If the brake
system warning light (red indicator) comes on while driving, immediately
stop the vehicle in a safe place and contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.

232 2-1. Driving procedures
PRIUS +_OM_OM47821E_(EE)
NOTICE
Hybrid battery (traction battery) charge
If the shift position is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid leaving the N
position selected for an extended period of time.
Situations where P position control system malfunctions are possible
If any of the following situations occurs, P position control system malfunc-
tions are possible.
Immediately stop the vehicle in a safe place on level ground, apply the park-
ing brake, and then contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
When the “WHEN PARKING, APPLY PARKING BRAKE SECURELY”
warning message appears on the instrument cluster. (P. 473)
When the parking lock system warning light is illuminated.
When everything except the shift position indicator selection frame is illu-
minated.
When the shift position indicator remains off.
Notes regarding shift lever and P position switch operation
Avoid repeatedly operating the shift lever and P position switch in quick suc-
cession.
The system protection function may activate and it will not be temporarily
possible to shift the shift position other than P. If this happens, please wait
for a while before attempting to change the shift position again.

Cargo and luggage
Take notice of the following information about storage precautions,
cargo capacity and load:
Stow cargo and luggage in the luggage compartment whenever
possible.
Be sure all items are secured in place.
To maintain vehicle balance while driving, position luggage
evenly within the luggage compartment.
For better fuel economy, do not carry unnecessary weight.

318 2-5. Driving information
PRIUS +_OM_OM47821E_(EE)
CAUTION
Secure all items in the occupant compartment, as they may shift and injure
someone in the event of an accident or sudden braking.
When you fold down the rear seats, long items should not be place directly
behind the front seats.
Never allow anyone to ride in the luggage compartment. It is not designed
for passengers. They should ride in their seats with their seat belts prop-
erly fastened. Otherwise, they are much more likely to suffer death or seri-
ous bodily injury, in the event of sudden braking or an accident.
NOTICE
If luggage is loaded on the roof (vehicles with a panoramic roof)
Observe the following precautions. Failure to observe them could lead to the
roof rack being damaged or deformed, or the roof rack falling off.
Do not install a roof rack which inter-
feres with the panoramic roof.
Do not load luggage directly onto the
panoramic roof.
