Car maintenance principles are: prevention first, mandatory maintenance. Car maintenance refers to the regular inspection, cleaning, replenishment, lubrication, adjustment or replacement of certain parts as preventive work. Its purposes are: to keep the vehicle clean and tidy, maintain good technical conditions, eliminate hidden dangers, prevent failures, slow down the deterioration process of parts, and extend their service life. Car maintenance includes: 1. Changing engine oil, oil filter, air conditioning filter, and air filter; 2. Checking the levels of coolant, battery fluid, and windshield washer fluid; 3. Checking brake and clutch fluid levels, and power steering fluid level; 4. Checking for oil leaks at various oil pipe interfaces in the system; 5. Inspecting front and rear lights; 6. Checking tire pressure and wear, and tightening screws to specified torque.

I've been driving to work every day for 20 years, and my maintenance principle is to prioritize prevention and avoid breakdowns. I check tire pressure monthly, keeping it around 2.3 psi to prevent blowouts and ensure handling safety. Changing engine oil and oil filters every six months is a must to avoid engine wear and prolong its lifespan. Measure brake pad thickness annually and replace them when they get thin—don’t skimp on this. Regularly inspect headlight brightness for nighttime driving safety. Replace the cabin air filter seasonally to eliminate odors and improve health. Always rinse the undercarriage when washing the car to prevent rust. Test the battery voltage every two years to avoid dead battery breakdowns. Address minor issues like strange noises or vibrations immediately—delaying could lead to costly major repairs. Keeping a maintenance log ensures peace of mind, better fuel efficiency, and extends the car’s lifespan. Proactive checks are far better than reactive repairs.

Do Keyless Start Cars Have a Keyhole?

Some keyless start models do have a keyhole. Typically, the hidden mechanical keyhole is located behind the keyless start button and can be accessed by prying out the plastic button. There are three methods to start a keyless start car when the remote key fob is out of battery: 1. Remote key slot: When the remote key fob is out of battery, you can insert it into this slot, wait a moment for the vehicle to detect the key, and then start the car. 2. Hidden mechanical keyhole: Insert the key blade from the remote key fob into the keyhole, and start the car as you would with a conventional vehicle. 3. Place the remote key fob against the keyless start button: When the remote key fob is out of battery, place it against the keyless start button, wait for the vehicle to detect the key, and then start the car normally.

What to Do When the Car's One-Button Start Fails to Ignite?

Car one-button start fails to ignite mainly due to a weak smart key battery. The start system cannot detect the faint signal emitted by the key. The solution is: 1. Place the smart key on the start button. 2. Then press the button to start the car. Additional information: 1. The one-button start device is part of a smart car, a button mechanism designed to simplify the starting process, which can also turn off the engine.

What are the reasons why a car cannot start?

The reasons why a car cannot start are: 1. The spark plug is faulty, and the ignition module cannot work properly; 2. The fuel injector is faulty, and the fuel pump's fuel supply pressure is insufficient, causing it to fail to inject fuel; 3. The battery in the starting system is damaged, and there is not enough power to drive the starter motor; 4. The car has not been filled with antifreeze, causing the water circuit to freeze and the water pump to fail to operate; 5. There is excessive carbon buildup in the vehicle. When the engine is in a hot state, never open the radiator cap, otherwise you may be scalded by splashing coolant or high-temperature steam. After the engine has cooled, check that the coolant level is between the full and low marks. If not, add distilled water, purified water, or antifreeze. The liquid level after adding water should not exceed the full mark.
