■When installing the filter cover
Slide the recessed part of the fil-
ter cover on the upper surface of the
upper filter case as shown in the
figure, and attach it so that it is lifted
toward the insertion part of the
cover attachment.
■Checking interval
Inspect and replace the air condi-
tioning filter according to the mainte-
nance schedule. In dusty areas or
areas with heavy traffic flow, early
replacement may be required. (For
scheduled maintenance information,
please refer to the “Owner’s Manual
Supplement” or “Scheduled Mainte-
nance”.)
■If air flow from the vents
decreases dramatically
The filter may be clogged. Check
the filter and replace if necessary.
WARNING
■When replacing the air condi-
tioning filter
Observe the following precau-
tions. Failure to do so may result
in the air conditioning system
operating during the procedure,
possibly resulting in injury.
●Check that the charging con-
nector is not connected
●Do not use the Remote Air Con-
ditioning System
NOTICE
■When using the air condition-
ing system
●Make sure that a filter is always
installed. Using the air condi-
tioning system without a filter
may cause damage to the sys-
tem.
●The filter is replaceable. When
cleaning the filter, do not clean
with water or an air gun.
■To prevent damage to the fil-
ter cover
When moving the filter cover in
the direction of arrow to release
the fitting, pay attention not to
apply excessive force to the
claws. Otherwise, the claws may
be damaged.

When trouble arises
1 Steadily step on the brake
pedal with both feet and
firmly depress it.
Do not pump the brake pedal
repeatedly as this will increase the
effort required to slow the vehicle.
2Shift the shift position to N.
If the shift position is shifted to
N
3 After slowing down, stop the
vehicle in a safe place by the
road.
4 Stop the EV system.
If the shift position cannot be
shifted to N
3 Keep depressing the brake
pedal with both feet to reduce
vehicle speed as much as
possible.
4 To stop the EV system: Press
and hold the power switch for
2 consecutive seconds or more, or press it briefly 3
times or more in succession.
5 Stop the vehicle in a safe
place by the road.
■If emergency stopped
The functions of the air conditioning,
etc., may be partially limited in order
to reduce the power consumption of
the 12-volt battery.
If your vehicle has to
be stopped in an emer-
gency
Only in an emergency, such
as if it becomes impossible
to stop the vehicle in the
normal way, stop the vehi-
cle using the following pro-
cedure:
Stopping the vehicle
WARNING
■If the EV system has to be
turned off while driving
Turning the EV system off while
driving will not cause a loss of
steering or braking control. How-
ever, power assist for the steering
wheel may be lost making it diffi-
cult to steer smoothly before stop-
ping the vehicle depending on the
remaining charge in the 12-volt
battery or usage conditions.
Decelerate as mu ch as possible
before turning off the EV system.

When trouble arises
 Fluid leaks under the vehicle
(Water dripping from the air
conditioning after use is nor-
mal.)
 Flat-looking tires or uneven
tire wear
 Excessive tire squeal when
cornering
 Strange noises related to the
suspension system
 Other noises related to the EV
system
 Stumbling or running roughly
 Appreciable loss of power
 Vehicle pulls heavily to one
side when braking
 Vehicle pulls heavily to one

road
 Loss of brake effectiveness,
WARNING
■While towing
●When towing using cables or
chains, avoid sudden starts,
etc., which place excessive
stress on the towing eyelets,
cables or chains. The towing
eyelets, cables or chains may
become damaged, broken
debris may hit people, and
cause serious damage.
●Do not perform any of the fol-
lowing as doing so may cause
the parking lock mechanism to
engage, locking the front
wheels and possibly leading to
an accident resulting in death or
serious injury:
• Unfasten the driver’s seat belt and open the driver’s door.
• Turn the power switch off.
■Installing towi ng eyelets to
the vehicle
Make sure that towing eyelets are
installed securely. If not securely
installed, towing eyelets may
come loose during towing.
NOTICE
■To prevent damage to the
vehicle during emergency
towing
Do not secure cables or chains to
the suspension components.
If you think something
is wrong
If you notice any of the fol-
lowing symptoms, your
vehicle probably needs
adjustment or repair. Con-
tact your Toyota dealer as
soon as possible.

• If the front camera is hot, such as after the vehicle is parked in the
sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera
• If a sunshade was used when the vehicle was parked, depending on
its type, the sunlight reflected from
the surface of the sunshade may
cause the temperature of the front
camera to become excessively
high
• If the front camera is cold, such after the vehicle is parked in an
extremely cold environment, use
the air conditioning system to
increase the temperature around
the front camera

When trouble arises
6 Open and close any of the
doors of your vehicle with the
power switch OFF.
7 Maintain the engine speed of
the second vehicle and start
the EV system of your vehi-
cle by turning the power
switch to ON.
8 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
9 Once the EV system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
10 Close the positive (+) battery
terminal cover.
Once the EV system starts,
have the vehicle inspected at
your Toyota dealer as soon as
possible.
■Starting the EV system when
the 12-volt battery is dis-
charged
The EV system cannot be started by
push-starting.
■To prevent 12-volt battery dis-
charge
●Turn off the headlights, the air
conditioning system, the audio
system, etc. while the EV system
is off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■Charging the 12-volt battery
The electricity stored in the 12-volt
battery will discha rge gradually even
when the vehicle i s not in use, due
to natural dischar ge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the EV system may be
unable to start. (The 12-volt battery
recharges automatically while the
EV system is operating.)
■When the 12-volt battery is
removed or discharged
●Information stored in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at your Toyota dealer.
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the 12-
volt battery is discharged. Use the
wireless remote c ontrol or the
mechanical key to lock or unlock
the doors.
●The EV system may not start on
the first attempt a fter the 12-volt
battery has recharged but will start
normally after the second attempt.
This is not a malfunction.
●The power switch mode is memo-
rized by the vehicle. When the 12-
volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
If you are unsure what mode the
power switch was in before the
12-volt battery discharged, be
especially careful when recon-
necting the 12-volt battery.
●If the 12-volt battery discharges, it
may not be possible to shift the
shift position to o ther positions. In
this case, the vehicle cannot be
towed without lifting both front
wheels because the front wheels
will be locked.
●The power back door (if equipped)
