Toyota CH-R. Steps to take in an emergency

  1. Connect a positive jumper cable clamp to the positive (+) battery terminal on your vehicle.
  2. Connect the clamp on the other end of the positive cable to the positive (+) battery terminal on the second vehicle.
  3. Connect a negative cable clamp to the negative (-) battery terminal on the second vehicle.
  4. Connect the clamp at the other end of the negative cable to a solid, stationary, unpainted metallic point away from the battery and any moving parts, as shown in the illustration.

4. Start the engine of the second vehicle. Increase the engine speed slightly and maintain at that level for approximately 5 minutes to recharge the battery of your vehicle.

5. Vehicles with a smart key system: Open and close any of the doors of your vehicle with the engine switch off.

6. Vehicles without a smart key system: Maintain the engine speed of the second vehicle and turn the engine switch to the "ON" position, then start the vehicle's engine.

Vehicles with a smart key system: Maintain the engine speed of the second vehicle and turn the engine switch to IGNITION ON mode, then start the vehicle's engine.

7. Once the vehicle's engine has started, remove the jumper cables in the exact reverse order from which they were connected.

8. To install the engine cover, conduct the removal procedure in reverse. After installing, check that the fixed pins are inserted securely.

Once the engine starts, have the vehicle inspected at your Toyota dealer 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 air conditioning 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.

■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 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 replacing the battery

  • Use a battery that conforms to European regulations.
  • Use a battery that the case size is same as the previous one, 20 hour rate capacity (20HR) is equivalent or greater, and performance rating (CCA) is equivalent or greater.

    Check the label on top of the battery for the battery size and specifications (ex. LN2, 60Ah, 520A).

    •  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 discharge and the engine may not be able to start.
  • For details, consult your Toyota dealer.

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