GS350/250_EE (OM30C36E)Connect the jumper cables according to the following procedure:
Connect a positive jumper cable clamp to the positive (+) bat-
tery terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery ter-
minal 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 bat-
tery and any moving parts, as shown in the illustration.
Start the engine of the second vehicle. Increase the engine speed

When trouble arises
GS350/250_EE (OM30C36E)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 any authorized
Lexus dealer or repairer, or another duly qualified and equipped
professional as soon as possible.
Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
To prevent 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 battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges auto-
matically during driving.)
When recharging or replacing the battery
For vehicles with an alarm: make sure the key is not inside the vehicle when
recharging or replacing the 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
entry & start system when the battery is discharged. Use the wireless
remote control or the mechanical key to lock or unlock the doors.
The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.
The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch
off.
If you are unsure what mode the engine switch was in before the battery
discharged, be especially careful when reconnecting the battery.

CAUTION
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the
flammable gas that may be emitted from the 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 termi-
nal.
Do not allow the other end of the jumper cable connected to the “+” termi-
nal 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
battery.
Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery:
When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, cloth-
ing or the vehicle body.
Do not lean over the battery.
In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
Do not allow children near the battery.
