CAUTION
When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not depress
the accelerator pedal while starting the hybrid system under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Caution while driving
If hybrid system failure occurs while the vehicle is moving, do not lock or open
the doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting in death or
serious injury.
Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehi-
cle, press and hold the power switch for more than 2 seconds, or press it briefly
3 times or more in succession. (P. 499)
However, do not touch the power switch while driving except in an emergency.
Turning the hybrid system off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop the
vehicle as soon as it is safe to do so.
NOTICE
To prevent 12-volt battery discharge
Do not leave the power switch in ACCESSORY or ON mode for long periods
of time without the hybrid system on.
If “ACCESSORY” or “IGNITION ON” is displayed on the meters while the
hybrid system is not operating, the power switch is not off. Exit the vehicle
after turning the power switch off.
Do not stop the hybrid system when the shift lever is in a position other than
P. If the hybrid system is stopped in another shift lever position, the power
switch will not be turned off but instead be turned to ACCESSORY mode. If
the vehicle is left in ACCESSORY mode, 12-volt battery discharge may
occur.
When starting the hybrid system
Do not depress the accelerator pedal unnecessarily.
If the hybrid system becomes difficult to start, have your vehicle checked by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional immediately.
Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional immediately.

Driving
IS300h_EE(OM53B95E)
This system allows the headlights and front position lights to be turned on
for 30 seconds when the power switch is off.
Pull the lever toward you and
release it with the light switch is in
or after turning the power
switch off.
Pull the lever toward you and release
it again to turn off the lights.
Daytime running light system
To make your vehicle more visible to other drivers, the front position lights turn
on automatically (at an increased intensity) whenever the hybrid system is started
and the parking brake is released. Daytime running lights are not designed for
use at night.
Headlight control sensor
Automatic light off system
When the light switch is in or : The headlights and front fog lights turn
off automatically if the power switch is turned to ACCESSORY mode or turned
off.
When the light switch is in : The headlights and all lights turn off automati-
cally if the power switch is turned to ACCESSORY mode or turned off.
To turn the lights on again, turn the power switch to ON mode, or turn the light
switch off once and then back to or .

Follow me home system
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 detect-
ing the level of ambient light and may cause
the automatic headlight system to malfunc-
tion.

2464-5. Using the driving support systems
IS300h_EE(OM53B95E)
To change the set speed, operate the lever until the desired set speed is
obtained.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily move
the lever in the desired direction.
Large adjustment: Hold the lever in
the desired direction.
The set speed will be increased or decreased as follows:
Fine adjustment: By approximately 1.6 km/h (1 mph) each time the lever is
operated.
Large adjustment: The set speed can be increased or decreased continually
until the lever is released.
Pulling the lever toward you can-
cels the constant speed control.
The speed setting is also canceled
when the brakes are applied.
Pushing the lever up resumes the
constant speed control.
Resuming is available when the
vehicle speed is more than approxi-
mately 40 km/h (25 mph).

Pressing the button changes the
vehicle-to-vehicle distance as fol-
lows:
Long
Medium
Short
The vehicle-to-vehicle distance is set
automatically to long mode when the
power switch is turned to ON mode.
If a vehicle is running ahead of you, the preceding vehicle mark will also be
displayed.
Select a distance from the table below. Note that the distances shown cor-
respond to a vehicle speed of 80 km/h (50 mph). Vehicle-to-vehicle dis-
tance increases/decreases in accordance with vehicle speed.
Pulling the lever toward you can-
cels the cruise control.
The speed setting is also canceled
when the brakes are applied.
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
Resuming is available when the
vehicle speed is more than approxi-
mately 40 km/h (25 mph).

Driving
IS300h_EE(OM53B95E)
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 120 m (400 ft.) ahead, determines the current vehicle-to-
vehicle following distance, and operates to maintain a suitable following
distance from the vehicle ahead.
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 neces-
sary, the system applies the brakes. A warning tone warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on
the vehicle ahead.
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 distance
set by the driver.
Example of acceleration
When there are no longer any vehicles ahead driving slower than the
set speed

2544-5. Using the driving support systems
IS300h_EE(OM53B95E)The system accelerates until the set speed is reached. The system then returns
to constant speed cruising.
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.
Warnings may not occur when
In the following instances, there is a possibility that the warnings will
not occur:
When the speed of the vehicle ahead matches or exceeds your vehi-
cle speed
When the vehicle ahead is traveling at an extremely slow speed
Immediately after the cruise control speed was set
At the instant the accelerator is applied
When constant speed control mode is selected, your vehicle will maintain
a set speed without controlling the vehicle-to-vehicle distance. Select this
mode only when vehicle-to-vehicle distance control mode does not func-
tion correctly due to dirt etc.
Press the “ON/OFF” button to
activate the cruise control.
Press the button again to deactivate
the cruise control.
Switch to constant speed control
mode.
(Push the lever forward and hold
for approximately 1 second.)
Constant speed control mode indicator will come on.
When in constant speed control mode, to return to vehicle-to-vehicle distance
control mode, push the lever forward again and hold for approximately 1 sec-
ond.
After the desired speed has been set, it is not possible to return to vehicle-to-
vehicle distance control mode.
