How to Turn on the Cold Air in an Automatic Transmission Car?

What is the reason for the car's genie lamp lighting up?

The genie lamp symbol is the oil pressure warning light, which serves as an indicator to check the car's oil level. Below are the relevant introduction and problem description of the oil pressure warning light: 1. Oil pressure warning light: The oil pressure warning light is used to display the oil pressure condition inside the engine. It is red in color and monitored via a pressure switch installed on the engine lubrication system's oil passage. 2. Reasons for lighting up: (1) Insufficient oil: A low oil level reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure. This insufficient lubrication causes increased wear on the crankshaft and bearings, as well as the cylinder liners and pistons. (2) Engine temperature too high: Excessive engine temperature accelerates the aging, deterioration, and thinning of the oil. This results in oil leakage through the gaps between components, lowering the pressure and triggering the oil warning light.

What is the wading depth of the Focus?

The wading depth of the Focus is 50cm. Here are the precautions for driving through water: 1. Assess the water depth: Determine the depth of the water. If the water does not exceed half the wheel height, it is safe to drive; otherwise, it is not advisable to continue. 2. Use snow mode: After entering a waterlogged section, slow down and drive carefully. For automatic transmission vehicles, it is best to use first gear and preferably switch to snow mode to prevent wheel slippage. 3. Continuous braking: After exiting the waterlogged section, apply the brakes several times in succession to evaporate the water from the brake discs to avoid affecting the vehicle's braking performance.

What are the reasons why a jack cannot be lifted?

Rust spots and peeling appear on the inner wall of the hydraulic cylinder of the hydraulic jack, affecting the sealing performance. Below are specific details about jacks: 1. Types: A-frame jacks, which have lower load-bearing capacity due to their structure, are mainly equipped on small vehicles. Diamond-shaped jacks have a more robust support structure compared to A-frame jacks. Screw jacks rely on their own threaded structure for self-locking to support the vehicle. 2. Precautions: Secure the vehicle properly, implement safety warning measures, ensure the base of the jack is firmly fixed, align it with the vehicle's chassis support points, and placing a spare tire under the car for added safety.

Does Parking on Damp Ground Have Any Impact?

Erosion of the chassis: In humid environments, the oxidation rate of metal accelerates. The failure rate of chassis components will increase. Below is relevant information: 1. Prevention methods: First, avoid driving on saline-alkali road sections: Saline-alkali substances (such as lime) easily react with metal, corroding the metal parts of the vehicle's chassis. Vehicles should avoid driving on such road sections or wash the body as soon as possible after driving on these sections. Second, avoid driving on beaches: Driving off-road on beaches, with wheels splashing sun-reflecting waves, may seem romantic, but long-term driving in such conditions will cause the vehicle's chassis to succumb to the salt corrosion of seawater, leading to rapid rusting. Then, avoid driving on gravel roads: When a vehicle passes over gravel roads, flying stones continuously hit the underside of the vehicle, damaging the anti-rust coating on the surface of chassis components, reducing the anti-rust capability of metal parts, shortening their service life, and increasing the owner's maintenance costs. Finally, avoid parking in damp areas: In poorly ventilated underground or cave-like parking lots, the moisture content in the air is extremely high, and the humidity is significant. Long-term parking of vehicles in these areas will accelerate the rusting of the chassis and body, affecting the vehicle's resale value. 2. Solutions: If rust occurs, remove the rust first. Rust removal can be done directly by polishing to eliminate the rust, followed by selecting some high-quality anti-rust and waterproof coatings to repair rusted holes.
