6828-2. Steps to take in an emergency
ES350_300h_OM_OM33B99U_(U)
■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 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 9 )
●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 engine may not start on the first atte mpt after the 12-volt battery has recharged
but will start normally after the second attempt. This is not a malfunction.
●The “START STOP ENGINE” 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 “START STOP ENGINE” switch off.
If you are unsure what mode the “START STOP ENGINE” switch was in before the
12-volt battery discharged, be especially careful when reconnecting the 12-volt
battery.
CAUTION
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prev ent accidentally igniting the flammable
gas that may be emitted from the 12-volt battery:
●Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to
come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with
each other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the 12-
volt battery.

■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 9 )
●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 fir st 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 disconnectin g 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.

CAUTION
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the
steam has subsided. The engine compartment may be very hot.
●Keep hands and clothing (especially a tie, a scarf or a muffler) away from the fans
and belts. Failure to do so may cause the hands or clothing to be caught, resulting
in serious injury.
●Do not loosen the radiator cap or the coolant reservoir cap while the engine and
radiator are hot. High temperatur e steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding cool
coolant to a hot engine too quickly can cause damage to the engine.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust etc.).
●Do not use any coolant additives.

When trouble arises
Start the hybrid system and check for the multi-information display.
If the message does not disappear:
Stop the hybrid system and contact your Lexus dealer.
If the message is not displayed:
Have the vehicle inspected at the nearest Lexus dealer.
CAUTION
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the
steam has subsided. The engine compartment may be very hot.
●After the hybrid system has been turned off, check that the indicator on the
“POWER” switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automatically
start, or the cooling fan may suddenly oper ate even if the gasoline engine stops.
Do not touch or approach rotating parts such as the fan, which may lead to fin-
gers or clothing (especially a tie, a scarf or a muffler) getting caught, resulting in
serious injury.
●Do not loosen the radiator cap or the coolant reservoir cap while the hybrid sys-
tem and radiator are hot. High temper ature steam or coolant could spray out.

■Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditio ns on a specified indoor labora-
tory test wheel.
Sustained high temperature can cause th e material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger car tires
must meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly inflated
and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.

ATTENTION
■Précautions relatives aux coussins gonflables SRS
●Ne touchez à aucun composant des coussins gonflables SRS immédiatement
après leur déploiement (gonflage), car ils pourraient être chauds.
●Si vous avez de la difficulté à respirer après le déploiement des coussins gonfla-
bles SRS, ouvrez une portière ou une glace pour laisser entrer l’air, ou quittez le
véhicule si vous pouvez le faire en toute sécurité. Dès que possible, nettoyez tous
les résidus afin d’éviter les irritations cutanées.
●Si les emplacements de stockage des coussins gonflables SRS, notamment le
tampon de volant et les garnitures des montants avant et arrière, sont endomma-
gés ou fissurés, faites-les remplacer par votre concessionnaire Lexus.
■Modification et mise au rebut des compos ants du système de coussins gonflables
SRS
Ne mettez pas le véhicule au rebut et n’effectuez aucune des modifications suivan-
tes sans d’abord consulter votre conces sionnaire Lexus. Les coussins gonflables
SRS pourraient fonctionner de manière in correcte ou se déployer (gonfler) acci-
dentellement, ce qui serait susceptible d’occasionner des blessures graves, voire
mortelles.
●Installation, retrait, démontage et ré paration des coussins gonflables SRS
●Réparations, modifications, retrait ou re mplacement du volant, du bloc d’instru-
mentation, du tableau de bord, des sièges ou du capitonnage des sièges, des
montants avant, latéraux ou arrière et des longerons du toit
