Driving
up, and the road could be slip-
pery.
●Drive carefully when it starts to
rain, as the road surface could be
especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■ECO Accelerator Guidance
(  P.108)
It is easier to drive in an Eco-friendly
manner by driving while referring to
the ECO Accelerator Guidance dis-
play. Also, by using the ECO Accel-
erator Guidance it is easier to
increase the “Eco Score” evaluation.
●When starting off:
While staying within the ECO
Accelerator Guidance range,
gradually depress the accelerator
pedal and accelerate to the
desired speed. If excessive accel-
eration is avoid ed, the “Start”
score will increase.
●When driving:
After accelerating to the desired
speed, release the accelerator
pedal and drive at a stable speed
within the ECO Acce lerator Guid-
ance range. By keeping the vehi-
cle within the E CO Accelerator
Guidance range, the “Cruise”
score will increase.
●When stopping:
When stopping the vehicle, early
releasing the accelerator pedal
will cause the “Stop” score to
increase.
■Restraining the hybrid system
output (Brake Override System)
●When the accelerator and brake
pedals are depressed at the same
time, the hybrid system output
may be restrained.
●A warning message is displayed
on the multi-information display and head-up display (if equipped)
while the system is operating.
(
 P.469)
■Restraining sudden start (Drive-
Start Control)
●When the following unusual oper-
ation is performed, the hybrid sys-
tem output may b e restrained.
• When the shift lever is shifted from
R to D, D to R, N to R, P to D
*, or
P to R* (D includes S) with the
accelerator pedal depressed, a
warning message appears on the
multi-information display and
head-up display (i f equipped). If a
warning message is shown on the
multi-information display and
head-up display (if equipped),
read the message and follow the
instructions.
• When the accelerator pedal is
depressed too much while the
vehicle is in reverse.
*: Depending on the situation, the
shift position may not be changed.
●When the TRAC is turned off
( P.337), sudden start restraint
control also does not operate. If
your vehicle have trouble escap-
ing from the mud or fresh snow
due to the sudden start restraint
control operation, deactivate
TRAC ( P.337) so that the vehi-
cle may become able to escape
from the mud o r fresh snow.
■Breaking in your new Toyota
To extend the life of the vehicle,
observing the following precautions
is recommended:
●For the first 200 miles (300 km):
Avoid sudden stops.
●For the first 500 miles (800 km):
Do not tow a trailer.
●For the first 600 miles (1000 km):
• Do not drive at extremely high
speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.

2124-1. Before driving
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a for-
eign country
Comply with the relevant vehicle
registration laws and confirm the
availability of the correct fuel.
(  P.518)
WARNING
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■When starting the vehicle
Always keep your foot on the
brake pedal while stopped with
the “READY” indicator is illumi-
nated. This prevents the vehicle
from creeping.
■When driving the vehicle
●Do not drive if y ou are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to a
difficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the
brake pedal using your left foot
may delay respon se in an emer-
gency, resulting in an accident.
●The driver should pay extra
attention to pedestrians when
the vehicle is powered only by
the electric motor (traction
motor). As there is no engine
noise, the pedestrians may mis-
judge the vehicle’s movement.
Even though the vehicle is
equipped with the Acoustic
Vehicle Alerting System, drive
with care as pedestrians in the
vicinity may still not notice the
vehicle if the surrounding area
is noisy.
●Do not drive the vehicle over or
stop the vehicle near flammable
materials such as leaves, paper
or rags.
The exhaust system and
exhaust gases can be
extremely hot. These hot parts
may cause a fire i f there is any
flammable material nearby.
●During normal driving, do not
turn off the hybrid system. Turn-
ing the hybrid s ystem off while
driving will not cause loss of
steering or braking control, how-
ever, power assist to the steer-
ing will be lost. This will make it
more difficult to steer smoothly,
so you should pull over and stop
the vehicle as soon as it is safe
to do so. In the event of an
emergency, such as if it
becomes impossible to stop the
vehicle in the normal way:
 P.457
●Use engine braking (downshift)
to maintain a safe speed when
driving down a steep hill.
Using the brakes continuously
may cause the brakes to over-
heat and lose effectiveness.
( P.241)

Driving
WARNING
●Do not adjust the position of the
steering wheel, the seat, or the
inside or outside rear view mir-
rors while driving.
Doing so may result in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, head or other parts
of their body are not outside the
vehicle.
●AWD models: Do not drive the
vehicle off-road. This is not an
AWD vehicle designed for off-
road driving. Drive with due care
if it becomes unavoidable to
drive off-road.
●AWD models: Do not drive
across a river or through other
bodies of water. This may cause
electric/electronic components
to short circuit, damage the
engine 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 b efore 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.
●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 lever
●Do not let the vehicle roll back-
ward while a fo rward driving
position is selected, or roll for-
ward while the shift lever is in R.
Doing so may result in an acci-
dent or damage to the vehicle.
●Do not shift the shift lever 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 sh ift lever to R
while the vehicle is moving for-
ward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to a
driving position while the vehicle
is moving backward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Moving the shift lever to N while
the vehicle is moving will disen-
gage the hybrid system. Engine
braking is not a vailable with the
hybrid system disengaged.

2144-1. Before driving
WARNING
●Be careful not to shift the shift
lever with the accelerator pedal
depressed.
Shifting the shift lever to a gear
other than P or N may lead to
unexpected rapid acceleration
of the vehicle that may cause an
accident and result in death or
serious injury. Doing so can
damage the transmission and
may result in a loss of vehicle
control.
■If you hear a squealing or
scraping noise (brake pad
wear limit indicators)
Have the brake pads checked and
replaced by your Toyota dealer as
soon as possible.
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 t he accelerator
pedal unnecessarily.
If the vehicle is in any gear other
than P or N, the vehicle may
accelerate suddenly and unex-
pectedly, causing an accident.
●In order to prev ent accidents
due to the vehicle rolling away,
always keep depressing the
brake pedal while stopped with
the “READY” indicator is illumi-
nated, and apply the parking
brake as necessary.
●If the vehicle is stopped on an
incline, in order to prevent acci-
dents caused by the vehicle roll-
ing 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 the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray cans, or soft
drink cans in the vehicle when it
is in the sun.
Doing so may result in the fol-
lowing:
• Gas may leak from a cigarette lighter or spray can, and may
lead to a fire.
• The temperature inside the vehicle may cause the plastic
lenses and plastic material of
glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray
over the interior of the vehicle,
and may also cause a short cir-
cuit in the vehicle’s electrical
components.
●Do not leave cigarette lighters in
the vehicle. If a cigarette lighter
is in a place such as the glove
box or on the floor, it may be lit
accidentally when luggage is
loaded or the se at is adjusted,
causing a fire.
●Do not attach adhesive discs to
the windshield or windows. Do
not place containers such as air
fresheners on the instrument
panel or dashboard. Adhesive
discs or containers may act as
lenses, causing a fire in the
vehicle.
