HS250h_U_75033U(Canada)
■Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco mode
Suitable for improving the fuel
economy, because the torque
corresponding to the accelera-
tor pedal depression amount
can be generated more
smoothly than it is in normal
conditions and the operation of
the air conditioning system will
be minimized.
When the Eco mode switch is
pressed, the “ECO MODE”
indicator comes on in the meter.
Po w e r m o d e
Suitable when the vehicle needs
to drive powerfully or travels in
mountainous areas.
When the power mode switch is
pressed, the “PWR MODE”
indicator comes on in the meter.

■Air conditioning system settings
When the “POWER” switch is turned on, the air conditioning system settings will be
set to those that were in use the last time the “POWER” switch was turned off.
●Air conditioning system settings are memorized individually on each electronic
key, so the settings reproduced will be specific to the key that is used.
●This feature is customizable at your Lexus dealer.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and ambi-
ent conditions. As a result, the following may occur:
●The system may switch automatically to recirculated air mode when the coolest
temperature setting is selected when the ambient temperature is high.
●Immediately after the button is pressed, the fan may stop for a while until warm
or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
