Instructions for my truck - turn on (full set) turn on and off the emergency gang 3 times (leave in full set mode) . The instrument will report recalibration mode and a beep will sound to indicate that you have a lower trim. Wheel order: left front, left right, rear right, rear left. Hold the device directly to the right of the valve stem, press and hold until you hear a beep. After everything is done, turn off the car and you can start and drive. If this does not happen, switch the car from off to on (auxiliary mode) 3 times and finish by switching on. Cheap and easy to use. I prefer to service and repair my truck myself for a number of reasons. 1) I'm very good at how things are made, if I do it myself I know that everything will be done right and no rough edges will be trimmed. Magazines over-tighten the nuts or not at all. 2) I like tinkering with cars and building/fixing things. I used to work in shops and construction and grew up with my uncle who was a handyman. I ride the table because I make more money, so having a few cold drinks, listening to music and yelling at my dog to back off is a great day for me. Also, I'm leaving my wife for a while lol. 3) save money. It's very annoying that all automakers are building these new cars and trucks to force people to either take them to the dealer or shop for basic jobs like changing tires, rear brakes (electronic parking brake needs to be put into service mode before removing calipers ). ). It's a smart business move, but thanks to the internet, YouTube, and similar products, you can still do most things yourself. According to my manual, oil changes every 7.5km I think (I do 5km), synthetic compound (of course I use full) and tire changes. With 9 liters of fully synthetic oil and a tire change, the price is ridiculously high ($100+). I can give or take at home for $40.
