What you will need
- Jumper Cables or Jump Box
- A car that runs
Follow the below-mentioned steps to jump-start your Lexus:
- Remove the emergency metal key from the keyfob and use it to open the driver’s door manually. Some Lexus cars have the keyhole on the driver’s door covered. Insert the metal key in the small slot below the door handle and pry out the cover.
- Park the vehicle that you are using to jump-start next to your Lexus. Keep the vehicles close so that the jumper cables can reach both batteries. Vehicles should not touch each other.
- Ensure that the ignition is off on both vehicles.
- Pull the hood release under the dashboard and open it.
- Go to the front of the car and slide your hand under the hood. You need to be near the Lexus logo.
- Locate the battery on your Lexus. Typically, in the engine bay, the driver’s side. If the battery is covered with a plastic cover, remove it to access the battery.
- Connect the red clamp to the battery positive (+) terminal.
- Attach the other red clamp to the car’s positive terminal (+) with a good battery.
Connect the black clamp to the car’s negative terminal (-) with a good battery.
- Connect the other black clamp on the unpainted bolt or the engine block. Engine block or strut tower bolts work best. Keep the clamp at least a foot away from the dead battery. It is not recommended to connect the black clamp directly to the dead battery’s negative (-) terminal.
- Start the engine with a good battery and run it up to 1500 rpm for around five minutes.
- Start your Lexus. If the vehicle has a Start/Stop button, press it with the keyfob.
- Remove the attached cables in reverse order as soon as your Lexus starts. Drive the vehicle for around 30 minutes before you turn off the engine.
If your lights turn on, but you hear a click when you press Start, the battery in your Lexus needs to charge. You need to take safety precautions before you start to jump-start your Lexus. Normally, the jumper cables have a set of clamps marked black and red. The red one should be used for positive and the black marked for negative.
Your Lexus battery is usually marked with ‘+’ for positive and ‘–‘ for the negative terminal. If the battery is dirty, you might need to wipe off the grime to check for the signs. Locate the jumper cables and ensure that the cables are in good condition. It is advisable to keep the jumper cables in your car along with a flashlight, first aid kit, and jacket.
Ways to Take Care of Your Car’s Battery
- Perform regular maintenance on your car’s electrical system, like cleaning the terminals from corrosion.
- Avoid short trips as much as possible to allow the battery to charge through your car’s charging system.
- Limit parasitic drain by having your electrical accessories disconnected when storing the vehicle.
- Limit extreme temperature exposure to reduce the strain on the batteries.
- You can install a battery disconnect switch when storing the vehicle to avoid draining the battery.
In conclusion, jump-starting a Lexus with a dead battery is a simple and effective solution for returning to the road. Whether you have a traditional gasoline-powered Lexus, a hybrid like the Lexus 450h or UX250h, or a luxury model like the Lexus RX350 or GS450h, the process of jump-starting is the same. Following the steps outlined in this guide, you can jump-start your Lexus quickly and easily. It is also important to take proper safety precautions, such as wearing gloves and ensuring the vehicles are not touching, to prevent electrical hazards. After jump-starting your Lexus, it is advisable to drive it for a while to allow the battery to recharge and to have it checked by a mechanic to determine the cause of the dead battery and prevent future incidents. With these tips, you can jump-start your Lexus confidently and keep your vehicle running smoothly, no matter the model.
