Driving
WARNING
■When driving the vehicle
●Do not drive if you 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 response 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 if the Acoustic Vehicle
Alerting System is operating,
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 if 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.
However, power assist for the
steering wheel may be lost mak-
ing it difficult to steer smoothly
before stopping the vehicle
depending on the remaining
charge in the 12-volt battery or
usage conditions. In this situa-
tion, 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 be comes impossible
to stop the vehicle in the normal
way:  P.547
●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.256)
●Do not adjust the position of the
steering wheel, the seat, inside
rear view mirror (if equipped),
Digital Rear-view Mirror (if
equipped) or outside rear view
mirrors while driving.
Doing so may resu lt 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.

2445-1. Before driving
WARNING
●Always apply the parking brake,
shift the shift position to P, stop
the hybrid system and lock the
vehicle.
Do not leave the vehicle unat-
tended while the “READY” indi-
cator is illuminated.
If the vehicle is parked with the
shift position in P but the park-
ing brake is not set, the vehicle
may start to move, possibly
leading to an accident.
●Do not touch the exhaust pipes
while the “READY” indicator is
illuminated or immediately after
turning the hybrid system off.
Doing so may cause burns.
■When taking a nap in the
vehicle
Always turn the hybrid system off.
Otherwise, if you accidentally shift
the shift position or depress the
accelerator pedal, this could
cause an accident or fire due to
hybrid system overheating. Addi-
tionally, if the vehicle is parked in
a poorly ventilated area, exhaust
gases may collect and enter the
vehicle, leading to death or a seri-
ous 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
brake system does not operate,
do not follow other vehicles
closely and avoid hills or sharp
turns that require braking.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing distance will increase. Have
your brakes fixed immediately.
●The brake system consists of 2
or more individual hydraulic sys-
tems; if one of the systems fails,
the other(s) will still operate. In
this case, the brake pedal
should be depressed more
firmly than usual and the brak-
ing distance will increase. Have
your brakes fixed immediately.
NOTICE
■When driving the vehicle
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the hybrid system out-
put.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■Avoiding damage to vehicle
parts
●Do not turn the steering wheel
fully in either direction and hold
it there for an extended period
of time.
Doing so may damage the
power steering.
●When driving over bumps in the
road, drive as slowly as possible
to avoid damaging the wheels,
underside of the vehicle, etc.

2545-2. Driving procedures
Modes can be changed by
pressing the power switch with
the brake pedal released. (The
mode changes each time the
switch is pressed.)
WARNING
■Stopping the hybrid system
in an emergency
●If you want to stop the hybrid
system in an emergency while
driving the vehicle, press and
hold the power switch for more
than 2 seconds, or press it
briefly 3 times or more in suc-
cession. (P.547)
However, do not touch the
power switch while driving
except in an emergency. Turn-
ing the hybrid system off while
driving will not cause loss of
steering or braking control.
However, power assist for the
steering wheel may be lost mak-
ing it difficult to steer smoothly
before stopping the vehicle
depending on the remaining
charge in the 12-volt battery or
usage conditions. In this situa-
tion, you should pull over and
stop the vehicle as soon as it is
safe to do so.
●If the power switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-information display
and a buzzer sounds.
●When restarting the hybrid sys-
tem after an emergency shut-
down, shift the shift position to
N and press the power switch
shortly and firmly.
■When parking
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time. If such a situation
cannot be avoided, park the
vehicle in an open space and
ensure that exhaust fumes do
not enter the vehicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem is operating, exhaust gases
may collect and enter the vehi-
cle.

within the lane to perform
evasive steering maneuvers
 The driver is operating the steering wheel
Vehicles with active steering
function: The brakes and steer-
ing are controlled to help avoid a
collision or reduce the impact of
a collision, regardless of the
evasive steering maneuvers
performed by the driver.
During assistance, the pre-colli-
sion warning will operate and a
message will be displayed to
warn the driver.
■Intersection collision avoid-
ance support (left/right
turn)
In situations such as the follow-
ing, if the system determines
that the possibility of a collision
is high, the pre-collision warning
and pre-collision braking will
operate.
Depending on the intersection,
assistance may not operate cor-
rectly.
