2023 TOYOTA PRIUS PRIME tires

2425-1. Before driving
WARNING
●Do not drive across a river or
through other bodies of water.
This may cause electric/elec-
tronic components to short cir-
cuit, damage the hybrid system
or cause other serious damage
to the vehicle.
●Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 85 mph (140 km/h)
unless your vehicle has high-
speed capability tires. Driving
over 85 mph (140 km/h) may
result in tire failure, loss of con-
trol and possible injury. Be sure
to consult a tire dealer to deter-
mine whether the tires on your
vehicle are high-speed capabil-
ity tires or not before driving at
such speeds.
■When driving on slippery
road surfaces
●Sudden braking, acceleration
and steering may cause tire
slippage and reduce your ability
to control the vehicle.
●Sudden acceleration, engine
braking due to shifting, or
changes in engine speed could
cause the vehicle to skid, result-
ing in an accident.
●After driving through a puddle,
lightly depress the brake pedal
to make sure that the brakes
are functioning properly. Wet
brake pads may prevent the
brakes from functioning prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.
■When shifting the shift posi-
tion
●Do not let the vehicle roll back-
ward while a fo rward driving
position is selected, or roll for-
ward while the shift position is in
R.
Doing so may result in an acci-
dent or damage to the vehicle.
●Do not shift the shift position to
P while the vehicle is moving.
Doing so can damage the trans-
mission 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
a driving position while the vehi-
cle is moving backward. Doing
so can damage the transmis-
sion and may result in a loss of
vehicle control.
●Changing the shift position to N
while the vehicle is moving will
disengage the hybrid system.
Regenerative braking is not
available with the hybrid system
disengaged.
●Do not shift the shift position
with the accelerator pedal
depressed. Changing the shift
position to any positions other
than P or N may lead to unex-
pected rapid acceleration of the
vehicle that may cause an acci-
dent and result in death or seri-
ous injury.
After changing the shift position,
make sure to confirm the cur-
rent shift position displayed on
the shift position indicator inside
the meter.

Driving
■The system can be operated
when
●The power switch is in ON.
●The intuitive parking assist func-
tion is on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●The shift position is in a position
other than P.
■If “Parking Assist Unavailable
Sensor Blocked” is displayed
on the multi-information display
A sensor may be covered with ice,
snow, dirt, etc. Remove the ice,
snow, dirt, etc., from the sensor to
return the system to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal. If an abnormality is displayed even
though there are no water droplets,
ice, snow or dirt, the sensor may be
operating abnormally. Have the
vehicle inspected by your Toyota
dealer.
■If “System Stopped See
Owner’s Manual” is displayed
on the multi-information display
Water may be continuously flowing
over the sensor surf ace, such as in
a heavy rain. When the system
determines that it is normal, the sys-
tem will return to normal.
■If “System Malfunction Visit
Your Dealer” is displayed on
the multi-info rmation display
There may be a sensor or voltage
malfunction. Have the vehicle
inspected by your Toyota dealer.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’s front and rear bumpers.
●Certain vehicle conditions and the
surrounding environment may
affect the ability of a sensor to cor-
rectly detect an object.
●Objects may not be detected if
they are too close to the sensor.
●There will be a short delay
between object detection and dis-
play. Even at low speeds, there is
a possibility that the object will
come within the sensor’s detection
areas before the display is shown
and the warning beep sounds.
●It might be difficult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
●It may be difficult to hear the
buzzer if buzzers for other sys-
tems are sounding.
●If the meter malfunctions, the
buzzer may not sound.
WARNING
●Keep your tires properly
inflated.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area. Doing so ma y result in the
sensor malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.
