241-1. For safe use
1-1.For safe use
Use only floor mats designed
specifically for vehicles of the
same model and model year as
your vehicle. Fix them securely
in place onto the carpet.
1Insert the retaining hooks
(clips) into the floor mat eye-
lets.
2 Turn the upper knob of each
retaining hook (clip) to secure
the floor mats in place.
Always align the marks . The shape of the retaining hooks
(clips) may differ from that shown in
the illustration.
Before driving
Observe the following
before starting off in the
vehicle to ensure safety of
driving.
Installing floor mats
WARNING
Observe the following precau-
tions.
Failure to do so may cause the
driver’s floor mat to slip, possibly
interfering with t
he pedals while
driving. An unexpectedly high
speed may result or it may
become difficult to stop the vehi-
cle. This could lead to an acci-
dent, resulting in death or serious
injury.
■When installing the driver’s
floor mat
●Do not use floor mats designed
for other models or different
model year vehicles, even if
they are Toyota Genuine floor
mats.
●Only use floor mats designed
for the driver’s seat.
●Always install the floor mat
securely using the retaining
hooks (clips) provided.
●Do not use two or more floor
mats on top of each other.
●Do not place the floor mat bot-
tom-side up or upside-down.

261-1. For safe use
Make sure that all occupants are
wearing their seat belts before
driving the vehicle. (P.27)
Use a child restraint system
appropriate for the child until the
child becomes large enough to properly wear the vehicle’s seat
belt. (
P.50)
Make sure that you can see
backward clearly by adjusting
the inside and outside rear view
mirrors properly. ( P.160, 161,
171)
WARNING
■For safe driving
Observe the following precau-
tions. Failure to do so may result
in death or serious injury.
●Do not adjust the position of the
driver’s seat while driving.
Doing so could cause the driver
to lose control of the vehicle.
●Do not place a cushion between
the driver or passenger and the
seatback. A cushion may pre-
vent correct pos ture from being
achieved, and reduce the effec-
tiveness of the seat belt and
head restraint.
●Do not place anything under the
front seats. Objects placed
under the front seats may
become jammed in the seat
tracks and stop the seat from
locking in place . This may lead
to an accident and the adjust-
ment mechanism may also be
damaged.
●Always observe the legal speed
limit when driving on public
roads.
●When driving over long dis-
tances, take regular breaks
before you start to feel tired.
Also, if you feel tired or sleepy
while driving, do not force your-
self to continue driving and take
a break immediately.

Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics differ
ent
from conventional vehicles. Be sure you are closely familiar
with the characteristics of your vehicle, and operate it with
care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction motor) according to driving condi-
tions, improving fuel efficiency and reducing exhaust emis-
sions.
System components

701-4. Hybrid system
electric motor (traction motor) is
used.
When the shift lever is in N, the
hybrid battery (traction battery)
is not being charged.
*: When the hybrid battery (traction battery) requires charging or the
engine is warming up, etc., the
gasoline engine will not automati-
cally stop. ( P. 7 0 )
■During normal driving
The gasoline engine is predomi-
nantly used. The electric motor
(traction motor) charges the
hybrid battery (traction battery)
as necessary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of
the hybrid battery (traction bat-
tery) is added to that of the gas-
oline engine via the electric
motor (traction motor).
■When braking (regenera-
tive braking)
The wheels operate the electric
motor (traction motor) as a
power generator, and the hybrid
battery (traction battery) is
charged.
■Regenerative braking
In the following si tuations, kinetic
energy is converted to electric
energy and deceleration force can
be obtained in conjunction with the
recharging of the hybrid battery
(traction battery).
●The accelerator pedal is released
while driving with the shift lever in D or S.
●The brake pedal
is depressed
while driving with t he shift lever in
D or S.
■EV indicator
The EV indicator comes on when
the vehicle is driven using only the
electric motor (traction motor) or the
gasoline engine is stopped.
■Conditions in which the gaso-
line engine may not stop
The gasoline engine starts and
stops automatically. However, it may
not stop automatic ally in the follow-
ing conditions:
●During gasoline engine warm-up
●During hybrid battery (traction bat-
tery) charging
●When the temperature of the
hybrid battery (traction battery) is
high or low
●When the heater is switched on
Depending on the circumstances,
the gasoline engine may also not
stop automatically in other situa-
tions.
■Charging the hybrid battery
(traction battery)
As the gasoline engine charges the
hybrid battery (trac tion battery), the
battery does not need to be charged
from an outside source. However, if
the vehicle is left parked for a long
time the hybrid battery (traction bat-
tery) will slowly dis charge. For this
reason, be sure to drive the vehicle
at least once every few months for
at least 30 minutes or 10 miles (16
km). If the hybrid battery (traction
battery) becomes fully discharged

and you are unable to start the
hybrid system, contact your Toyota
dealer.
■Charging the 12-volt battery
 P. 4 7 9
■After the 12-volt battery has dis-
charged or when the terminal
has been removed and installed
during exchange, etc.
The gasoline engine may not stop
even if the vehicle is being driven by
the hybrid battery (traction battery).
If this continues for a few days, con-
tact your Toyota dealer.
■Sounds and vibrations specific
to a hybrid vehicle
There may be no engine sound or
vibration even though the vehicle is
able to move with the “READY” indi-
cator is illuminated. For safety, apply
the parking brake and make sure to
shift the shift lever to P when
parked.
The following sounds or vibrations
may occur when the hybrid system
is operating and are not a malfunc-
tion:
●Motor sounds may be heard from
the engine compartment.
●Sounds may be heard from the
hybrid battery (traction battery)
under the second seats when the
hybrid system starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the hybrid battery (traction
battery), under the second seats,
when the hybrid system is started
or stopped.
●Sounds from the hybrid system
may be heard when the back door
is open.
●Sounds may be heard from the
transmission when the gasoline
engine starts or stops, when driv-
ing at low speeds, or during idling.
●Engine sounds may be heard
when accelerating sharply.
●Sounds may be heard due to
regenerative braking when the
brake pedal is depressed or as
the accelerator pedal is released.
●Vibration may be felt when the
gasoline engine starts or stops.
●Cooling fan sounds may be heard
from the air intake vents under the
second seats.
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do n ot dispose of the
vehicle yourself.
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of
the vehicle’s approach. The
sound will stop when the vehicle
speed exceeds approximately
22 mph (35 km/h).
■Acoustic vehicle alerting sys-
tem
In the following cases, the acoustic
vehicle alerting system may be diffi-
cult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the acoustic vehicle alerting
system is installed on the front of the
vehicle, it may be more difficult to
hear from the rear of the vehicle
compared to the front.

limited and the distance that the
vehicle can be driven using the
electric motor (traction motor) is
reduced, the fuel economy may
be reduced.
When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks the high voltage current
and stops the fuel pump to mini-mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. (
P.456)
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
The hybrid system may not start. In
this case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
NOTICE
■Hybrid battery (traction bat-
tery) air intake vent
●Make sure not to block the air
intake vent with anything, such
as a seat cover, plastic cover, or
luggage.
The input/output of the hybrid
battery (traction battery) may be
restricted, leading to a reduction
in hybrid battery (traction bat-
tery) output and a malfunction.
●Periodically clean the air intake
vents to prevent them from clog-
ging. ( P.420)
●Do not allow liquid or foreign
material to enter the air intake
vent as this may cause a short
circuit and damage the hybrid
battery (traction battery).
