2023 TOYOTA HIGHLANDER ECO mode

3104-5. Using the driving support systems
■AWD system operation sounds
and vibrations when switching
between AWD and front wheel
drive (if equipped)
When the vehicle switches from
AWD to front wheel drive and vice
versa, operation sounds and vibra-
tions may be generated, but this is
not a malfunction.
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the engine
off. The EPS syst em should return
to normal within 10 minutes.
■Automatic reactivation of
TRAC, Trailer Sway Control and
VSC systems
After turning the TRAC, Trailer
Sway Control and VSC systems off,
the systems will be automatically
re-enabled in the following situa-
tions:
●When the engine switch is turned
OFF
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when
vehicle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■If a message about AWD is
shown on the multi-information
display (AWD models)
Perform the following actions.
●“AWD System Over-heated
Switching to 2WD Mode.” AWD
system is overheated. Stop the
vehicle in a safe place with the
engine running.
*
If the message disappears after a
while, there is no problem. If the
message remains, have the vehi-
cle inspected by your Toyota
dealer immediately.
●“AWD System Over-heated 2WD
Mode Engaged.” AWD system
has been temporarily released
and switched to front-wheel drive
due to overheating. Stop the vehi-
cle in a safe place with the engine
running.
*
If the message disappears after a
while, AWD system will automati-
cally recover. If the message
remains, have the vehicle
inspected by your Toyota dealer
immediately.
●“AWD system Malfunction 2WD
Mode Engaged Visit Your Dealer.”
A malfunction occurs in the AWD
system. Have the vehicle
inspected by your Toyota dealer
immediately.
*: When stopping the vehicle, do not stop the engine until the display
message has turned off.
■Secondary Collision Brake
operating conditions
The system operates when the SRS
airbag sensor de tects a collision
while the vehicle is in motion.
However, the system does not oper-
ate when the components are dam-
aged.

3255-1. Using the air conditioning system and defogger

Interior features
recirculated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up
by the vehicle is still drawn into the
vehicle after closing the windows, it
is recommended that the air intake
mode be set to outside air mode and
the fan speed to any setting except
off.
■Outside/recirculated air mode
●Setting to the r ecirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to c ool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air co nditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode ( P.300)
■When the outside temperature
is low
The dehumidification function may
not operate even when the “A/C”
switch is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning system to the outside air
mode.
●During use, various odors from
inside and outside the vehicle may enter into and accumulate in the
air conditioning system. This may
then cause odor
to be emitted
from the vents.
●To reduce potential odors from
occurring:
• It is recommended that the air conditioning system be set to out-
side air mode prior to turning the
vehicle off.
• The start timing of the blower may
be delayed for a short period of
time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.
■Air conditioning system opera-
tions when the engine is
stopped due to the Stop & Start
system (vehicles with Stop &
Start system)
When the engine is stopped due to
Stop & Start system operations, the
automatic air conditioning cooling,
heating and dehumidification func-
tions turn off and the fan speed is
decreased according to the outside
temperature etc. or air blowing
stops. To stop the air conditioning
system from turning off, press the
Stop & Start cancel switch and
refrain from using the Stop & Start
system.
■When the windshield is fogged
up and the engine is stopped
due to the Stop & Start system
(vehicles with Stop & Start sys-
tem)
Press the windshield defogger
switch to restart the engine and
defog the windshield.
If the windshield continuously fogs
up, press the Stop & Start cancel
switch and refrain from using the
Stop & Start system.

■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
In order to reduce t he air condition-
ing power consumption, the air con-
ditioning system may switch to
recirculated air mode automatically.
This may also reduce fuel consump-
tion.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning “A/C” on will dehu-
midify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows
may fog up more easily.

switch, eco air conditioning mode
turns on.
When a drive mode other than Eco
drive mode is sele cted, eco air con-
ditioning mode may turn off.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air co nditioning perfor-

begins to operate. Air outlets and
fan speed are automatically
adjusted according to the tempera-
ture setting and humidity.
2 Adjust the temperature set-
ting. 3
To stop the operation, press
the “OFF” switch.
If the fan speed setting or air
flow modes are operated, the
automatic mode indicator goes
off. However, automatic mode
for functions other than that
operated is maintained.
■Using automatic mode
Fan speed is adjusted automati-
cally according to the temperature
setting and the am bient 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.
This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. Unnecessary air
conditioning is suppressed, con-
tributing to increased fuel effi-
ciency.
Front seat concentrated airflow
mode operates in the following
situations.
 No passengers are detected
in the rear seats
 The windshield defogger is
not operating
While operating, the indicator illumi-
nates on the S-FLOW mode switch.
