All cars are so individual that when buying a new car, you will have to get used to its technical features for some time. And in order to save yourself from unpleasant surprises, be sure to ask the seller in detail about all the nuances of driving and maintaining the car.
When buying a car, be sure to ask the manager or former owner about all the features of the car. For example, it happens that the car must run on 92 gasoline, but the owner filled only 95. In this case, you will have to follow the established tradition to avoid problems. It happens that some cars categorically do not "tolerate" some gas stations, after refueling at which they begin to twitch and "sneeze" due to their sensitivity to low-quality gasoline. It is better to learn about all these nuances in advance.
If the car has an alarm, ask where the valet alarm button is located. You should be given two keys and two key fobs from the alarm. But in any case, find the instructions for using the alarm and reprogram the key fobs. In this case, it will no longer be possible to open the car with old alarm consoles.
Open the hood and ask to be shown where the antifreeze, windscreen washer fluid, oil is poured. Some car owners have incidents when water is poured into the coolant tank, or in the worst case, an “anti-freeze” for glass. If you want to change the oil to a better one, you can only do this with a planned replacement. And you can add only the one that is already in use.
Sit in the salon and check the operation of all units. Ask to be shown how the dimensions, low and high beams are turned on. Ask if you need to turn them off when you get out of the car or if they turn off automatically (Fiat, Skoda).
You should be explained the principle of operation of the on-board computer (if any), the multimedia system. Be sure to ask how the brushes work. After all, they have several positions and several speed modes.
If the car has a robotic gearbox, you need to remember all the nuances of switching to the "mechanics" mode.
