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 le vel for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Open and close any of th e doors of your vehicle with the “START STOP
ENGINE” switch off.
Maintain the engine speed of the seco nd 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 wh ich they were connected.
Once the engine starts, have the vehi cle 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 compon ents 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
■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 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.
