WARNING
■Trailer Sway Control precaution
The Trailer Sway Control system is not
able to reduce trailer sway in all situa-
tions. Depending on many factors such
as the conditions of the vehicle, trailer,
road surface and driving environment,
the Trailer Sway Control system may not
be effective. Refer to your trailer owner’s
manual for information on how to tow
your trailer properly.
■If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or seri-
ous injury.
●Firmly grip the steering wheel. Steer
straight ahead. Do not try to control
trailer sway by turning the steering
wheel.
●Begin releasing the accelerator pedal
immediately but very gradually to
reduce speed. Do not increase speed.
Do not apply vehicle brakes.
If you make no extreme correction with
the steering or brakes, your vehicle and
trailer should stabilize. ( P.260)

■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air
mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a

lated air mode is used.
■When driving on dusty roads

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 recirculated air mode tem-
porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
●Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.
■Registering air conditioning settings to
electronic keys (vehicles with driving
position memory)
●Unlocking the vehicle using an electronic
key and turning the engine switch to
IGNITION ON mode will recall that
key’s registered air conditioning settings.
●When the engine switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
●The system may not operate correctly if
more than one electr onic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.
●The doors that can recall the air condi-
tioning setting when unlocked using the
smart access system with push-button
start can be changed.
* For details, con-
tact your Lexus dealer.
*: The doors that can recall the driving posi-
tion memory are changed at the same

■Operation of the air conditioning sys-
tem in Eco mode
●In the Eco mode, the air conditioning sys-
tem is controlled as follows to prioritize
fuel efficiency
• Engine speed and compressor operation
controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic
mode is selected
●To improve air conditioning performance,
perform the following operations
• Adjust the fan speed
• Adjust the temperature setting
• Turn off Eco mode
●Even when the driving mode is set to Eco
mode, the air conditioning eco mode can
be turned off by selecting the
