Where is the tire pressure reset button for the Patrol?

The Patrol does not have a separate tire pressure reset button; the tire pressure reset must be performed via a computer. However, if all four tires in use are confirmed to have tire pressure monitoring devices, balancing the air pressure in all four tires can achieve a reset. What to do if the tire pressure is insufficient: If no damage is visible on the car's tires, simply inflate them to the normal tire pressure and then reset the tire pressure system. If a puncture is found upon inspecting the car's tires, drive to a repair shop promptly to have the tire patched before reinflating it. If the tire pressure warning appears again some time after inflation but there is no puncture, it might be due to air leakage caused by a deformed wheel rim. It is recommended to check the wheel rim and replace it if necessary. The working principle of the tire pressure monitoring system is: It uses pressure sensors installed inside the tires to measure the tire pressure and wireless transmitters to send the pressure information from inside the tire to a central receiver module.
As someone who has driven a Patrol for four or five years, I've studied the button location several times. If you're driving the new Y62 model, after starting the car, there's a small button on the side of the dashboard below the steering wheel, marked with a tire and exclamation point icon. When the tire pressure warning light comes on, simply press and hold it for 3-5 seconds to reset. For older models, it might be hidden near the fuse box inside the glove compartment. Once after fixing a flat tire, I specifically opened the glove box and felt a raised round button near the right plastic clip. If you still can't find it, you can open the hood and check the backup button on the firewall on the driver's side. Just remember, the operation only works when the ignition is on, and the reset is successful when the flashing light on the dashboard goes off. Also, after fixing the tire, wait a few minutes for the system to relearn the tire pressure values before resetting, or else it's all for nothing.
Last time at my shop, we just fixed this issue on a Patrol. First, turn the ignition on but don't start the engine, then crouch near the driver's seat and feel below the steering wheel to the left. There's a rubber button about the size of a fingernail at the triangular junction between the center console and steering column - press it and you'll hear a beep as the warning light turns off. If you can't find it, there's another method: open the glove compartment, remove two screws from the right inner plastic panel, and you'll find a backup reset button on the black control box. Actually, the tire pressure monitoring system is particularly sensitive to improper operation - after inflating tires, always confirm all four tires reach around 2.5bar before resetting, otherwise it could be dangerous at highway speeds.
