Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
Shift lever
Operate the shift lever gently
and ensure correct shifting
operation.When shifting to the D
or R positions, move the
shift lever along the shift
gate.
To shift to the N position,
slide the shift lever to the
left and hold it. The shift
position will change to N.
Shifting to B is only pos-
sible when shift position
D is selected.
The shift lever will
always return to this
position after a shifting
operation.
When shifting from P to D or R,
from D to R, or from R to D,
ensure that the brake pedal is
being depressed and the vehicle
is stationary.
Shift position indicator
When selecting the shift posi-
tion, make sure that the shift
position has been changed to
the desired position by checking
the shift position indicator pro-
vided on the instrument panel.
When any shift position other
than D or B is selected, the
arrow toward B disappears from
the shift position indicator.

■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.

■For the shift positions
●When the “POWER” switch is off, the shift position cannot be changed.
●When the “POWER” switch is in ON mode, the shift position can only be
changed to N.
●When the “READY” indicator is on, the shift position can be changed from P to
D, N o r R .
●The shift position can only be changed to B directly from D.
In addition, if the shift position is changed in any of the following situations, the
buzzer will sound and the shifting operation will be disabled or the shift position will
automatically change to N. When this happens, select an appropriate shift position.
● Situations where the shifting operation will be disabled:
• When the shift lever is changed from P to another position without depress-
ing the brake pedal.
• When the shift position is changed from P or N to B.
● Situations where the shift position will automatically change to N:
• When the P position switch is pressed while the vehicle is running.
• When shift position R is selected when the vehicle is moving forward.
• When shift position D is selected when the vehicle is moving in reverse.
• When the shift position is changed from R to B.
■Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift position is
in R.
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply engine
braking.
• When the vehicle is driven at high speeds, compared to ordinary gasoline- fueled vehicles, the engine braking deceleration is felt less than that of other
vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will become low.
Usually, select the D position.

■Power mode automatic deactivation
Power mode is automatically deactivated if the “POWER” switch is turned off after
driving in power mode.
■Customization
Settings (e.g. Reverse warning buzzer) can be changed.
(Customizable features →P. 5 74 )
CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in
an accident.
■For the shift lever
Do not hang anything on the shift lever.
Doing so could prevent the shift lever fr om returning to position, causing unex-
pected accidents to occur when the vehicle is in motion.
NOTICE
■Situations where P position control system malfunctions are possible
If any of the following situations occurs, P position control system malfunctions are
possible.
Immediately stop the vehicle in a safe place on level ground, apply the parking
brake, and then contact your Lexus dealer.
●When the “P Lock Malfunction” warning message appears on the multi-informa-
tion display. ( →P. 5 0 2 )
●When the P position switch indicator flashes.
●When the shift position symbols (such as P and R) are flashing on the shift posi-
tion indicator.
●When the shift position indicator remains off.
■When in heavy traffic
If shift position N is selected, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid leaving the N position
selected for an extended period of time.

Parking brake
■Parking brake engaged warning buzzer
The buzzer sounds to indicate that parking brake is still engaged (with the vehicle
having reached a speed of 3 mph [5 km/h]). (→P. 506)
■Usage in winter time
See “Winter driving tips” for parking brake usage in winter time. ( →P. 2 4 4 )
NOTICE
■Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components over-
heating, which may affect braking performance and increase brake wear.
To set the parking brake, fully
depress the parking brake pedal
with your left foot while
depressing the brake pedal with
your right foot.
(Depressing the pedal again
releases the parking brake.)

2-3. Operating the lights and windshield wipers
HS250h_U_75033U(Canada)Press the “ENTER” switch to
change to OFF.
The “AFS OFF” indicator will come
on.
Each pressing of the switch turns
AFS on and off.
Press the menu switch to change to
the normal display.
■Daytime running light system (if equipped)
●To make your vehicle more visible to other drivers, the headlights turn on auto-
matically (at a reduced intensity) whenever the hybrid system is started and the
parking brake is released. Daytime running lights are not designed for use at
night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.
■Headlight control sensor
■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 seconds
after a door is opened and closed if the “POWER” switch is turned to ACCES-
SORY mode or turned off. (The lights turn off immediately if on the key is
pressed after all the doors are locked.)
●When only the tail lights come on: The tail lights turn off automatically if the
“POWER” switch is turned to ACCESSORY mode or turned off and the
driver’s door is opened. The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

Driving in vehicle-to-vehicle distance control mode
This mode employs a sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead and to judge the distance between
your vehicle and those the vehicle ahead of you.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehi-
cle distance can also be set by operating the vehicle-to-vehicle distance con-
trol.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes. A warning tone warns you when the
system cannot decelerate sufficiently to prevent your vehicle from closing in
on the vehicle ahead.

2-4. Using other driving systems
HS250h_U_75033U(Canada)Example of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration
When there are no longer any vehicles ahead driving slower than the
set speed.
The system slowly accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via the cruise control is not possible, the display will
flash and the buzzer will sound to alert the driver. An example of this
would be if another driver cuts in front of you while you are following a
vehicle. Apply the brakes to ensure an appropriate vehicle-to-vehicle dis-
tance.
■Dynamic radar cruise can be set when
●The shift position is in D.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-vehicle
distance control mode has been used. The mode also cannot be switched from
constant speed control to vehicle-to-vehicle distance control mode. Turn the sys-
tem off by pressing the “ON-OFF” button, and turn it on again.
■Accelerating
The vehicle can be accelerated normally. After acceleration, the set speed resume.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may
decrease below the set speed in order to maintain the distance to the vehicle
ahead.
