Before driving
■The moon roof can be operated when
The “POWER” switch is in ON mode.
■Operating the moon roof after turning the hybrid system off
The moon roof can be operated for approximately 43 seconds even after the
“POWER” switch is turned to ACCESSORY mode or turned off. It cannot, how-
ever, be operated once either front door is opened.
■Jam protection function
If an object is detected between the moon roof and the frame while the moon roof is
closing or tilting down, travel is stopped and the moon roof opens slightly.
■To reduce moon roof wind noise
Drive with the moon roof opened to slightly before the fully open position as driving
with the moon roof opened fully will cause wind noise.
■Sunshade
The sunshade can be opened and closed manually. However, the sunshade will
open automatically when the moon roof is opened.
■Door lock linked moon roof operation
●The moon roof can be opened and closed using the mechanical key.*
(  P. 5 4 0 )

●No valuables or other personal items are left in the vehicle.
■Deactivating or stopping the alarm

2-1. Driving procedures
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (P. 5 5 8 )
■For efficient use
●Select the D position when driving.
In the N position, the gasoline engine op erates but electricity cannot be gener-
ated. The hybrid battery (traction battery) will discharge, requiring unnecessary
engine power to recharge.
●Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the electric motor (traction motor) with-
out having to use gasoline engine power.
●Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
●Select the P position when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the N position selected for an extended period of time may discharge
the hybrid battery. The vehicle cannot ru n if the hybrid battery is discharged.
■Eco-friendly driving
■Customization
Settings for Eco Driving Indicator Light can be changed.
(Customizable features P. 5 8 0 )
During Eco-friendly acceleration (Eco driv-
ing), Eco Driving Indicator Light will turn on.
When the accelerator pedal is depressed
excessively, and when the vehicle is stopped,
the light turns off.
Eco Driving Indicator Li ght will operate when
the vehicle is being driven with the shift posi-
tion in D at a speed of about 80 mph (130
km/h) or below. The indicator will not operate
when the vehicle is in power mode or EV
drive mode. ( P. 1 5 2 ,

2-1. Driving procedures
■Operation of the “POWER” switch
●When operating the “POWER” switch, one short, firm press is enough. If the
switch is pressed improperly, the hybrid system may not start or the “POWER”
switch mode may not change. It is not necessary to press and hold the switch.
●If attempting to restart the hybrid system immediately after turning the
“POWER” switch off, the hybrid system may not start in some cases. After turn-
ing the “POWER” switch off, please wait a few seconds before restarting the
hybrid system.
■Automatic P position selection function
●When the shift position is in a positi on other than P, pressing the “POWER”
switch with the vehicle stopped comple tely will cause the shift position to
change to P automatically, and then the “POWER” switch will turn off.
●When turning the “POWER” switch off from a position other than P, firmly
depress the brake pedal and confirm that the shift position* has changed to P
before slowly releasing the brake pedal.
*: Even after the instrument panel display has been turned off, the shift position
indicator will continue to be displayed for several seconds.
●If the P position control system malfun ctions, the “POWER” switch will not be
able to be turned off. In such a case, the switch can be turned off by applying the
parking brake.
When the system malfunctions, immediately have your vehicle serviced by your
Lexus dealer.
CAUTION
■When starting the hybrid system

When driving
■Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If it can-
not be turned on, a buzzer will sound and a message will be shown on the multi-
information display.
●Vehicle speed is about 19mph (30km/h) or more.
●The hybrid battery (traction battery) is low.
In general, the remaining battery level in dicated in the “Energy Monitor” display
is level 3 or lower. ( P. 3 3 )
● The temperature of the hybrid system is high.
The vehicle has been left in the sun, driv en on a hill, driven at high speeds, etc.
●The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 32°F (0°C) for a
long period of time etc.
●The gasoline engine is warming up.
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
●The windshield defogger is in use.
■Automatic cancellation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in
the following situations. When EV drive mo de is canceled, a buzzer will sound and
the EV drive mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low.
In general, the remaining battery level in dicated in the “Energy Monitor” display
is level 2 or lower. ( P. 3 3 )
●Vehicle speed becomes more than about 19 mph (30 km/h).
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
■ Possible driving distance when driving in EV drive mode
In EV drive mode, it is possible to drive up to about several hundred yards if driving
at a speed of about 19 mph (30 km/h) or less. (The distance that is possible
depends on the hybrid battery [traction battery] level and driving conditions.)

2-1. Driving procedures
■Fuel economy
HS250h is designed to achieve the best possible fuel economy during normal driv-
ing (using the gasoline engine and electric motor [traction motor]). Driving in EV
drive mode more than necessary may lower fuel economy.
CAUTION
■Caution while driving
When driving in EV drive mode, pay special attention to the area around the vehi-
cle. Because there is no engine noise, pedestrians, people riding bicycles or other
people and vehicles in the area may not be aware of the vehicle starting off or
approaching them, so take extra care while driving.

156
2-1. Driving procedures
■Shift position purpose
*: For good fuel economy and noise redu ction, the D position should usually
be used.
■ P position switch
The shift position can be changed to P through use of the P position
switch.
Fully stop the vehicle and keep
depressing the brake pedal, and
then press the P position switch.
When the shift position is
changed to P, the switch indica-
tor comes on.
Check that the P position indi-
cator is illuminated on the shift
position indicator.
●Changing the shift position from P to other positions:
• While depressing the brake pedal firmly, operate the shift lever. If the
shift lever is operated without depressing the brake pedal, the buzzer
will sound and the shifting operation will be disabled.
• The shift position cannot be changed from P to B directly.
