IS300h_EE(OM53C61E)
■Battery-saving function (vehicles with entry function)
The battery-saving function will be activated in order to prevent the electronic key bat-
tery and the 12-volt battery from being discharged while the vehicle is not in operation
for a long time.
●In the following situations, the smart entry & start system may take some time to unlock
the doors.
• The electronic key has been left within approximately 2 m (6 ft.) of the outside of the
vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.
●If the smart entry & start system has not been used for 14 days or longer, the doors can-
not be unlocked at any door except the driver’s door. In this case, hold the driver’s door
handle, or use the wireless remote control or mechanical key, to unlock the doors.
■Electronic Key battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
Press twice while pressing and holding
. Confirm that the electronic key indica-
tor flashes 4 times.
While the battery-saving mode is set, the smart
entry & start system cannot be used. To cancel
the function, press any of the electronic key but-
tons.

1944-1. Before driving
IS300h_EE(OM53C61E)
■For efficient use
●Shift the shift lever to D when driving.
In the N position, the gasoline engine operates but electricity cannot be generated. 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 deceleration
will make more effective use of the electric motor (traction motor) without 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.
●Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time may discharge
the hybrid battery (traction battery). The vehicle cannot be driven if the hybrid battery
(traction battery) is discharged.

Driving
IS300h_EE(OM53C61E)
If the hybrid system is stopped with the shift lever in a position other than P, the
power switch will not be turned off but instead be turned to ACCESSORY
mode. Perform the following procedure to turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that “Turn Power OFF” is displayed on the multi-information display
and then press the power switch once.
Check that “Turn Power OFF” on the multi-information display is off.
■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON mode (the
hybrid system is not operating) for more than an hour with the shift lever in P, the power
switch will automatically turn off. However, this function cannot entirely prevent 12-volt
battery discharge. Do not leave the vehicle with the power switch in ACCESSORY or
ON mode for long periods of time when the hybrid system is not operating.

Driving
IS300h_EE(OM53C61E)
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 vehicle, press
and hold the power switch for more than 2 seconds, or press it briefly 3 times or more
in succession. (→P. 4 9 5 )
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,
however, power assist to the steering will be lost. This will make it more difficult to steer
smoothly, 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 profes-
sional 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.

CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehicle
skidding to the side or spinning.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid battery (traction battery) will not be charged even
when the engine is running. Therefore, if the vehicle is left with the shift lever in N for a
long period of time, the hybrid battery (traction battery) will discharge, and this may
result in the vehicle not being able to start.

■Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY mode
and the driver’s door is opened while the lights are turned on.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■Operation guide display (vehicles with rain-sensing windshield wipers only)
When the headlight switch is operated to and from the “AUTO” position, the current sta-
tus is displayed on the meters for a few seconds to show that AUTO mode is activated/
deactivated. (→P. 1 1 8 )
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: →P. 5 7 9 )
NOTICE
