Toyota 4Runner Owners Manual / When trouble arises / If the engine will not start / If the vehicle battery is discharged
The following procedures may be used to start the engine if the vehicle's battery is discharged.
You can also call your Toyota dealer or a qualified repair shop.
If you have a set of jumper (or booster) cables and a second vehicle with a 12-volt battery, you can jump start your vehicle by following the steps below.
Connect the jumper cables according to the following procedure:
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.
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 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.
When the battery is removed or discharged
Make sure that the key is not inside the vehicle when recharging or replacing the battery. The key may be locked in the vehicle if the alarm is activated.
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.)
Precautions when the battery is discharged (vehicles with a smart key system)
· In some cases, it may not be possible to unlock the doors using the smart key 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 START STOP” 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 START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” 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 terminal.
· 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.
NOTICE
When handling jumper cables
When connecting the jumper cables, ensure that they do not become entangled in the cooling fans or belt.
丰田4Runner：如果汽车电池已放电
Toyota 4Runner用户手册/出现故障时/如果发动机无法启动/如果车辆电池已放电
如果车辆的电池电量已耗尽，可以使用以下过程来启动发动机。
您也可以致电丰田经销商或合格的维修店。
如果您有一组跨接电缆（或增强电缆）和另一辆带有12伏电池的车辆，则可以按照以下步骤快速启动车辆。
按照以下步骤连接跨接电缆：
1.将正极跨接电缆夹连接到车辆的正极（+）电池端子。
2.将正极电缆另一端的线夹连接至第二辆汽车的正极（+）电池端子。
3.将负极电缆夹连接到第二辆汽车的负极（-）电池端子上。
4.如图所示，将负极电缆另一端的线夹连接到远离电池和任何移动部件的坚固，固定，未上漆的金属点。
启动第二个引擎
车辆。稍微提高发动机转速，并保持在该水平约5分钟，即可为车辆的电池充电。
配备智能钥匙系统的车辆
仅：在关闭“发动机启动停止”开关的情况下打开和关闭车辆的任何车门。
保持发动机转速
通过将“ ENGINE START STOP”（发动机启动停止）开关转到“点火开启”模式（带有智能钥匙系统的车辆）或将引擎开关转到“ ON”位置（没有智能钥匙系统的车辆）来启动第二辆车辆并启动车辆的发动机。
一旦汽车的引擎
首先，按照与连接时完全相反的顺序卸下跨接电缆。
发动机启动后，请尽快在丰田经销商处对车辆进行检查。
电池放电后启动发动机
不能通过强制启动来启动引擎。
为防止电池放电
·发动机关闭时，关闭大灯和音响系统。
·当车辆长时间低速行驶（例如，交通繁忙）时，请关闭所有不必要的电气组件。
取出电池或放电后
给电池充电或更换电池时，请确保钥匙不在车内。如果激活了警报，则钥匙可能会锁定在车辆中。
给电池充电
由于自然放电和某些电器的排泄作用，即使在不使用车辆时，存储在电池中的电量也会逐渐放电。如果车辆长时间搁置，电池可能会放电，发动机可能无法启动。 （电池在行驶过程中会自动充电。）
电池放电时的注意事项（带智能钥匙系统的车辆）
·在某些情况下，电池放电后，可能无法使用智能钥匙系统解锁门。使用无线遥控器或机械钥匙锁定或解锁门。
·电池充电后，发动机可能不会在第一次尝试时启动，但会在第二次尝试后正常启动。这不是故障。
·车辆存储“ ENGINE START STOP”开关模式。
重新连接电池后，系统将返回到电池放电之前的模式。断开电池连接之前，请关闭“发动机启动停止”开关。
如果不确定在电池放电之前“ ENGINE START STOP”开关处于哪种模式，请在重新连接电池时特别小心。
警告
避免电池起火或爆炸
请遵守以下预防措施，以防止意外点燃电池可能散发出的可燃气体：
·确保每条跨接电缆都连接到正确的端子，并且不要无意中与预期的端子接触。
·请勿使跨接电缆的+和-夹相互接触。
·请勿吸烟，使用火柴，点烟器或在电池附近放明火。
电池注意事项
电池包含有毒和腐蚀性的酸性电解液，而相关零件则包含铅和铅化合物。处理电池时，请遵守以下注意事项：
·使用电池时，请始终戴上安全眼镜，并注意不要使任何电池液体（酸）接触皮肤，衣服或车身。
·请勿将电池倾斜。
·如果电池液接触到皮肤或眼睛，请立即用水冲洗患处并寻求医疗救护。
将湿海绵或布放在患处上，直到可以就医。
·处理电池支架，端子和其他与电池有关的零件后，请务必洗手。
·请勿让儿童靠近电池。
