2023 TOYOTA MIRAI climate control

3285-6. Driving tips
Owners Manual_USA_M62064_en
Perform the following according
to the driving conditions:
Do not try to forcibly open a
window or move a wiper that
is frozen. Pour warm water
over the frozen area to melt
the ice. Wipe away the water
immediately to prevent it from
freezing.
 To ensure proper operation of
the climate control system
fan, remove any snow that
has accumulated on the air
inlet vents in front of the wind-
shield.
 Check for and remove any
excess ice or snow that may
have accumulated on the
exterior lights, outside rear
view mirrors, windows, vehi-
cle’s roof, chassis, around the
tires or on the brakes.
 Remove any snow or mud
from the bottom of your shoes
before getting in the vehicle.
Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions. 
Turn automatic mode of the
parking brake off. Otherwise,
the parking brake may freeze
and not be able to be
released automatically.
Also, avoid using the following
as the parking brake may
operate automatically, even if
automatic mode is off.
• Brake hold system
Park the vehicle and shift the
shift position to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing it from being
released. If the vehicle is
parked without setting the
parking brake, make sure to
block the wheels.
Failure to do so may be dan-
gerous because it may cause
the vehicle to move unexpect-
edly, possibly leading to an
accident.
 When the parking brake is in
automatic mode, release the
parking brake after shifting
the shift position to P.
( P.192)
 If the vehicle is parked without
setting the parking brake,
confirm that the shift position
cannot be moved out of P.
 If the vehicle is left parked
with the brakes damp in cold
temperatures, there is a pos-
sibility of the brakes freezing.

*: If equipped
Touch “All auto” on the air condi-
tioning control screen.(P.346)
The indicator on the “All auto” con-
trol screen illuminates, and the
automatic air conditioning system,
seat heaters and v entilators, and
heated steering wheel operate in
automatic mode.
If any of the system is operated
manually, the indicator turns off.
However, all other functions con-
tinue to operate in automatic mode.
■Automatic air conditioning
system ( P.340)
The temperature can be
adjusted independently for each
seat.
■Seat heaters (if equipped)
and seat ventilators (if
equipped) ( P.351)
Heating or ventilation is auto-
matically selected according to
the set temperature of the air
conditioning system, the out-
side temperature, etc.

Interior features
■Using automatic mode
Fan speed is adjusted automati-
cally according to the temperature
setting and the ambient conditions.
Therefore, the fan may stop for a
while until warm or cool air is ready
to flow immediately after the auto-
matic mode switch is pressed.
Vehicles with DUAL-ZONE
climate control
To turn on the “DUAL” mode,
select the “SYNC” switch on the
air conditioning control screen.
The driver’s side temperature con-
trol switches can be used to adjust
the temperature for the driver’s and
passenger’s side. To enter individ-
ual mode, operate t he passenger’s
side temperature control switches
or select the “SYNC” switch again.
When the “SYNC” mode is on, the
indicator illuminates on the “SYNC”
switch.
Vehicles with 3-ZONE cli-
mate control
To turn on the “3-ZONE” mode,
select the “SYNC” switch on the
air conditioning control screen.
The driver’s side temperature con-
trol switches can be used to adjust
the temperature for the driver’s and
passenger’s side. To enter individ-
ual mode, operate t he passenger’s
side temperature control switches
or select the “SYNC” switch again. When the “SYNC” mode is on, the
indicator illuminates on the “SYNC”
switch.
This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats.
Vehicles with 3-ZONE climate
control: When the front passen-
ger seat is not occupied, airflow
may switch to only the driver’s
seat.
Unnecessary air conditioning is
suppressed, contributing to
increased fuel efficiency.
Front seat concentrated airflow
mode operates in the following
situations.

started, if passengers move
around inside or enter/exit the
vehicle, the system cannot accu-
rately detect the presence of pas-
sengers and automatic airflow
control will not operate.
■Operation of manual airflow
control
Even if the function is manually
switched to directi ng airflow to only
the front seats, whe n a rear seat is
occupied, it may automatically direct
airflow to all seats.

Vehicle specifications
tration of the U.S. Department of
Transportation.
It provides the purchasers
and/or prospective purchasers
of Toyota vehicles with informa-
tion on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
■DOT quality grades
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades. Quality grades
can be found where applicable
on the tire sidewall between
tread shoulder and maximum
section width.
For example: Treadwear 200 Trac-
tion AA Temperature A
■Treadwear
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course.
For example, a tire graded 150
would wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative perfo rmance of tires
depends upon the actual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
■Traction AA, A, B, C
The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
