Maintenance and care
CAUTION
■Replacing light bulbs
●Turn off the lights. Do not attempt to replace the bulb immediately after turning
off the lights.
The bulbs become very hot and may cause burns.
●Do not touch the glass portion of the light bulb with bare hands. Hold the bulb by
the plastic or metal portion.
If the bulb is scratched or dropped, it may blow out or crack.
●Fully install light bulbs and any parts used to secure them. Failure to do so may
result in heat damage, fire, or water entering the headlight unit. This may damage
the headlights or cause condensation to build up on the lens.
■Discharge headlights (if equipped)
●Contact your Lexus dealer before replacing the discharge headlights (including
light bulbs).
●Do not touch the discharge headlight’s high voltage socket when the headlights
are turned on.
An extremely high voltage of 25000 V will be discharged and could result in
death or serious injury by electric shock.
●Do not attempt to take apart or repair the headlight bulbs, connectors, power
supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
■To prevent damage or fire
●Make sure bulbs are fully seated and locked.
●Check the wattage of the bulb before installing to prevent heat damage.

Refuel the vehicle.
●There may be a malfunction in the immobilizer system. ( →P. 8 2 )
●There may be a malfunction in the steering lock system.
●The hybrid system may be malfunctioning due to an electrical problem
such as electronic key battery depletion or a blown fuse. However,
depending on the type of malfunction, an interim measure is available
to start the hybrid system. ( →P. 8 0 0 )
One of the following may be the cause of the problem:
●The 12-volt battery may be discharged. ( →P. 8 0 9 )
●The 12-volt battery terminal connections may be loose or corroded.
Reasons for the hybrid system not st arting vary depending on the situa-
tion. Check the following and perform the appropriate procedure:
The hybrid system will not start even though the correct starting
procedure is being followed. ( →P. 2 0 4 )
The interior lights and headlights are dim, or the horn does not

8067-2. Steps to take in an emergency
ES350 300h_OM_OM33A01U_(U)
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.
■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 engine may be unable to start. (The 12-volt battery recharges
automatically during driving.)

When trouble arises
■Starting the hybrid system when the 12-volt battery is discharged

■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

■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 the key is not inside the vehicle when recharging or replacing the 12-volt
battery to prevent the doors from being locked with the key left inside the vehicle
when the alarm operates.
●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.
