When trouble arises
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks and tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with a tire
pressure warning valve and transmitter. If a tire goes flat, the tire pressure warning
light will not turn off even though the flat tire has been replaced with the spare tire.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure
warning valve and transmitter. The tire pressure warning light will turn on if the tire
inflation pressure of the spare tire is low. If a tire goes flat, the tire pressure warning
light will not turn off even though the flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly
→P. 7 0 7
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1 minute when
the “START STOP ENGINE” <“POWER”> switch is turned to IGNITION ON
mode, have it checked by your Lexus dealer.
■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the warn-
ing buzzer may sound.
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an audio
sound.

Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the pos-
itive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery terminal
on the second vehicle.
Connect the clamp at the other end of the negative cable to a solid,
stationary, unpainted metallic point away from the 12-volt battery
and any moving parts, as shown in the illustration.
Start the engine of the second ve hicle. 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 “START STOP
ENGINE” switch off.
Maintain the engine speed of the second vehicle and start the engine of
your vehicle by turning the “START STOP ENGINE” switch to IGNI-
TION ON mode.
Once the vehicle’s engine has started, remove the jumper cables in the
exact reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at your Lexus dealer as
soon as possible.
■Starting the engine when the 12-volt battery is discharged
The engine cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the engine 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 trouble arises
■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 certain elec-
trical appliances. If the vehicle is left for a long time, the 12-volt battery may dis-
charge, and the hybrid system may be unable to start. (The 12-volt battery recharges
automatically while the hybrid system is operating.)
■When recharging or replacing the 12-volt battery
●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. 8 7 )
●In some cases, it may not be possible to unlock the doors using the smart access
system with push-button start when the 12-volt battery is discharged. Use the wire-
less 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 malfunction.
●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 bat-
tery 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.
