2013 Lexus IS300h door lock

5508-2. Steps to take in an emergency
IS300h_EE(OM53B95E)
Ensure that the shift lever is in P and depress the brake pedal.
Touch the Lexus emblem side of
the electronic key to the power
switch.
When the electronic key is detected,
a buzzer sounds and the power
switch will turn to ON mode.
When the smart entry & start system
is deactivated in customization set-
ting, the power switch will turn to
ACCESSORY mode.
Firmly depress the brake pedal and check that is shown on the
multi-information display.
Press the power switch.
In the event that the hybrid system still cannot be started, contact any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
Stopping the hybrid system
Shift the shift lever to P and press the power switch as you normally do when
stopping the hybrid system.
Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the elec-
tronic key battery be replaced immediately when the battery is depleted. (P.
472)
Alarm (if equipped)
Using the mechanical key to lock the doors will not set the alarm system.
If a door is unlocked using the mechanical key when the alarm system is set, the
alarm may be triggered.
Changing power switch modes
Release the brake pedal and press the power switch in step above.
The hybrid system does not start and modes will be changed each time the switch
is pressed. (P. 210)
When the electronic key does not work properly
Make sure that the smart entry & start system has not been deactivated in the
customization setting. If it is off, turn the function on.
(Customizable features P. 575)
Check if battery-saving mode is set. If it is set, cancel the function. (P. 150)

When trouble arises
IS300h_EE(OM53B95E)
Once the hybrid system has started, remove the jumper cables in the
exact reverse order from which they were connected.
Once the hybrid system starts, have the vehicle inspected at any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped
professional as soon as possible.
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
To prevent 12-volt battery discharge
Turn off the headlights and the audio system while the hybrid system is off.
Turn off any unnecessary electrical components when the vehicle is running at
a low speed for an extended period, such as in heavy traffic.
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the 12-volt battery
may discharge, and the hybrid system may be unable to start. (The 12-volt bat-
tery recharges automatically while the hybrid system is operating.)
When recharging or replacing the 12-volt battery
For vehicles with an alarm: Make sure that the key is not inside the vehicle
when recharging or replacing the 12-volt battery. The key may be locked in the
vehicle if the alarm is activated. (P. 98)
In some cases, it may not be possible to unlock the doors using the smart entry
& start system when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
The hybrid system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a mal-
function.
The power switch mode is memorized by the vehicle. When the 12-volt battery
is reconnected, the system will return to the mode it was in before the 12-volt
battery was discharged. Before disconnecting the 12-volt battery, turn the
power switch off.
If you are unsure what mode the power switch was in before the 12-volt battery
discharged, be especially careful when reconnecting the 12-volt battery.

Vehicle customization
When the speed-detecting automatic door lock and shift-linked automatic door
lock are both on, the door lock operates as follows.
• When shifting the shift lever to any position other than P, all the doors will
be locked.
• If the vehicle is started with all doors locked, the speed-detecting automatic
door lock will not operate.
• If the vehicle is started with any door unlocked, the speed-detecting auto-
matic door lock will operate.
When the smart entry & start system is off, the entry unlock function cannot be
customized.
When the doors remain closed after unlocking the doors and the timer activated
automatic door lock function activates, signals will be generated in accordance
with the operation buzzer volume and operational signal (Emergency flashers)
function settings.
When customizing using the Remote Touch or Lexus Display Audio controller
Stop the vehicle in a safe place, apply the parking brake, and shift the shift lever
to P. Also, to prevent 12-volt battery discharge, leave the hybrid system operating
while customizing the features.
CAUTION
During customization
As the hybrid system needs to be operating during customization, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may col-
lect and enter the vehicle. This may lead to death or a serious health hazard.
NOTICE
During customization
To prevent 12-volt battery discharge, ensure that the hybrid system is operating
while customizing features.
