How to Start the Envision When There's No Power?

[AngelinaDella]

Methods to start the Envision without power: The vehicle's battery is not a regular one but a specialized AGM battery for start-stop systems, requiring different charging methods. It needs to be removed for charging before restarting or wait for roadside assistance. Due to the frequent engine restarts by the start-stop system, the battery must support high-current discharges repeatedly, possess strong charge acceptance capabilities, and have high capacity to meet the electrical demands of in-car appliances when the engine is off. Taking the Envision 2021 532T Two-Wheel Drive Leading Model as an example, its body dimensions are 4694mm in length, 1839mm in width, and 1686mm in height, with a wheelbase of 2750mm. It is a 5-door, 5-seat SUV with a fuel tank capacity of 66 liters. The powertrain is equipped with a 1.5L inline four-cylinder turbocharged engine, delivering a maximum power of 124kW and a maximum torque of 250Nm.

Last time my Envision's battery was dead and couldn't start the car, it took me a long time to figure it out. The safest method is to find another working car for a jump start. Remember that the Envision's battery is located under the front passenger seat—just lift the carpet to see the terminals. When using jumper cables, always connect the positive terminal (red clamp) of the donor car first, then the positive terminal of the dead battery. Next, connect the negative terminal (black clamp) to the donor car's battery negative terminal, and finally attach the other end to a grounding point in the engine bay of the dead car. Never connect directly to the negative terminal of the dead battery! After connecting, wait two minutes to let the battery charge a bit before starting. Once the car is running, keep the engine on for at least twenty minutes. Always remember to turn off headlights and AC when parking. If installing a dashcam, it's best to connect it to the fuse box for constant power.

When encountering a completely dead battery, I usually start by checking the dashboard. If even the dashboard lights don't come on, it's almost certainly a battery issue. When jump-starting, pay special attention not to reverse the positive and negative terminals. If the Enclave's battery is inconvenient to access inside the vehicle, there are emergency terminals in the engine compartment. After a successful temporary jump-start, don't turn off the engine immediately—it's best to drive to an auto repair shop to test the battery's health. Typically, a battery lasts only three to five years. Prevention is more important; for long-term parking, it's recommended to start the engine for twenty minutes weekly or disconnect the negative terminal. Keeping an emergency power source in the car is quite practical—it's about the size of a power bank and can be a lifesaver in critical moments.

Last month, my Envision stalled in the underground garage, and I called the insurance company for roadside assistance. The technician brought a jump starter and directly clamped it onto the red positive terminal in the engine bay and a metal part of the car body—it started in just three seconds. If you're doing it yourself, make sure to use jumper cables with thick copper cores, as thin ones can overheat. When the rescue vehicle provides power, rev the engine to 2000 rpm for faster charging. After starting, don’t rush to turn off the AC or headlights—let the alternator charge the battery longer. Once, I successfully jump-started the car and drove for half an hour, but after turning it off to shop, it wouldn’t start again. Turns out the battery was too old to hold a charge.

Don't panic if your battery runs low! My go-to solution is using a roadside assistance app – it's a free service from my insurance, so why not use it? If you prefer DIY, ask a friend for a jump start. Remember, the Buick Enclave has a red cover marked with a '+' on the left side of the engine bay, specifically designed for jump-starting – much easier than removing seats. Opt for 3-meter-long jumper cables to avoid parking the cars too close together, and make sure the metal clamps don't touch during connection. After starting, turn off the AC and stereo to let the battery recharge, then drive to a repair shop to check the voltage. When replacing the battery, don't just go for the cheapest option – AGM start-stop batteries are more expensive but last longer.

When the battery is dead, first try using the mechanical key of the smart key to open the door. Once inside, press the start button. If the dashboard flashes but the engine doesn't turn over, it's likely a dead battery. I've tried three methods: calling the 4S store is the fastest but expensive, insurance company rescue is free but you have to wait, and the most convenient is to keep a coin-sized emergency power source plugged into the cigarette lighter. If the battery is completely dead and you can't even open the door, there's a mechanical switch under the small cover on the right side of the trunk. Special note for the Envision with auto start-stop: it requires a dedicated battery, as a regular battery will fail within six months. After starting, turn on the hazard lights and drive slowly to the repair shop, avoiding stalling along the way.
