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 stopped.
• 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 the battery is removed or discharged

• Information stored in the ECU is cleared. When the battery is depleted, have the vehicle inspected at your Lexus dealer.
  Some systems may require initialization.
  ( P.415)
  When removing the battery terminals When the battery terminals are removed, the information stored in the ECU is cleared. Before removing the battery terminals, contact your Lexus dealer.

Charging the battery
The electricity stored in the battery will dis-charge gradually even when the vehicle is not in use, due to natural discharge and the draining effects of certain 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 automatically during driving.)

When recharging or replacing the battery

In some cases, it may not be possible to unlock the doors using the smart access system with push-button start 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 dis-charged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-charged, be especially careful when reconnecting the battery.

When replacing the battery

• Use a battery that conforms to European regulations.
  Use a battery that the case size is same as the previous one (LN3), 20 hour rate capacity (20HR) is equivalent (70Ah) or greater, and performance rating (CCA) is equivalent (592A) or greater.
  • If the sizes differ, the battery cannot be properly secured.
  • If the 20 hour rate capacity is low, even if the time period where the vehicle is not used is a short time, the battery may dis-charge and engine may not be able to start.
• For details, consult your Lexus dealer.

WARNING
When removing the battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal contacts any metal in the surrounding area when the positive (+) terminal is removed, a spark may occur, leading to a fire in addition to electrical shocks and death or serious injury.

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 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 battery.

Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while related parts contain lead and lead compounds. Observe the following precautions 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, clothing or the vehicle body.
  Do not lean over the battery.

WARNING

• 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.

When replacing the battery
When the vent plug and indicator are close to the hold down clamp, the battery fluid (sulfuric acid) may leak.

NOTICE
When handling jumper cables
When connecting the jumper cables, ensure that they do not become entangled in the cooling fan or engine drive belt.

If your vehicle overheats
The following may indicate that your vehicle is overheating.

• The engine coolant temperature gauge (P.68, 71) is in the red zone or a loss of engine power is experienced. (For example, the vehicle speed does not increase.)

WARNING
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 fan and belts. Failure to do so may cause the hands or clothing to be caught, resulting in serious injury.
  While the engine and radiator are hot, do not loosen or remove the coolant inlet cap or coolant reservoir cap. High temperature 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 additive.
