When trouble arises
Depress the brake pedal.
Touch the Lexus emblem side of
the electronic key to the power
switch.
If any of the doors is opened or
closed while the key is being
touched to the switch, an alarm will
sound to indicate that the start func-
tion cannot detect the electronic key.
Press the power switch within 10 seconds of the buzzer sounding,
keeping the brake pedal depressed.
In the event that the hybrid system still cannot be operated, contact any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
Stopping the hybrid system
Set the parking brake, shift the shift position 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.
530)
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. (P. 9 3 )
Changing power switch modes
Within 10 seconds of the buzzer sounding, release the brake pedal and press the
power switch.
The hybrid system does not start and modes will be changed each time the switch
is pressed. (P. 198)

Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Open and close any of the doors of your vehicle with the power switch
off.
Maintain the engine speed of the second vehicle and start the hybrid
system of your vehicle by turning the power switch to ON mode.
Make sure the “READY” indicator comes on. If the indicator light
does not come on, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Once the hybrid system has started, remove the jumper cables in the
exact reverse order from which they were connected.
Close the exclusive jump starting terminal cover, and reinstall the fuse
box cover to its original position.
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.
When the 12-volt battery is removed or discharged
The hybrid system may not start. (P. 507)
If the 12-volt battery discharges while the shift position is in P, it may not be
possible to shift the shift position to other positions. In this case, the vehicle
cannot be towed without lifting both front wheels because the front wheels will
be locked. (P. 562)
When the 12-volt battery is reconnected, start the hybrid system and confirm
that the shift position can be changed to each position using the shift position
indicator.
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 acti-
vated. (P. 9 3 )
