Due to the lack of power, related electric functions are restricted. When the car battery is dead, the trunk can still be opened using the emergency switch. Below is relevant information about the car trunk: 1. Maintenance: Keep the trunk clean and use the side mesh pockets correctly. Most cars come equipped with these pockets to store items that are prone to rolling, such as flashlights or small fire extinguishers. They don’t take up much space, but it’s not advisable to pile items together, as they may fall out of the mesh pockets due to bumps during driving. 2. Precautions: Flammable and explosive items are prohibited. The interior of a car is a relatively enclosed space, and in summer, after exposure to the sun, the temperature inside can become very high. Storing flammable or explosive items in the trunk may lead to spontaneous combustion or explosions due to the high temperature.

A dead car battery causing the trunk to not open is a very common issue, mainly because many modern cars use electronic locks. Once the battery is dead, the trunk lock becomes completely inoperable. I've experienced this problem myself, and I remember how frantic I was at the time. Later, I discovered a hidden mechanical keyhole on the trunk lid—just insert the small metal piece from the key fob, twist it, and the trunk pops open. I recommend checking your vehicle's manual; some cars even have a passage behind the rear seats where you can reach in and open the trunk. Looking back, I regret not keeping an emergency jump starter cable on hand—these cost just a few dozen dollars and can save you from such embarrassing situations. Also, remember to regularly check your battery's condition, especially if it's over three years old. Old batteries can fail suddenly, so don’t wait until you're stranded to panic.

Where is the oil filter located on the Atenza?

The oil filter of the Atenza is located on the side of the engine intake pipe. Below is some relevant information: 1. The Atenza comes with 2.0 and 2.5 displacement options, combined with the SKYACTIV engine, making it suitable for young people with financial capability who pursue fashion. The predecessor of the Atenza was the highly popular Mazda6, so its exterior design carries some resemblance to its predecessor. 2. The Atenza is also the first model in the Mazda brand to feature ALH adaptive LED headlights, which offer variable light distribution. This provides ideal illumination for drivers at night, significantly improving visibility in dark environments and maximizing driving safety. 3. In terms of body dimensions, the Atenza measures 4870/1840/1451 mm in length, width, and height, with a wheelbase of 2830 mm. Even though it focuses on handling, the Atenza still meets the seating space requirements of B-segment car users without compromising on either aspect.

What kind of engine oil should be used for Changan CS75?

Changan CS75 should use engine oil that meets the GB11121 standard with a quality grade of SL or above and a viscosity grade of 5W-30, depending on the temperature. Below is the relevant introduction: 1. Engine oils on the market can be simply divided into mineral oil and synthetic oil based on their base oil. Synthetic oils are further divided into: full synthetic and semi-synthetic. 2. Among them, full synthetic oil is the highest grade. The main differences between them are: synthetic oil can be used in a wider temperature range, has a longer service life, and is more expensive; for the same oil film requirements, synthetic oil can achieve the goal with lower viscosity, while mineral oil requires a relatively higher viscosity to meet the same requirements. 3. Depending on the actual usage, consider adding combustion improvers and additives such as fuel system cleaners to help remove carbon deposits.

What is Eco Pro Mode?

Eco-Pro is the energy-saving driving mode for vehicles. ECO is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard illuminates, it indicates that the vehicle's economy mode has been activated. The Eco mode is categorized into active and non-active types. The difference lies in the fact that the active mode has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light immediately illuminates, and the vehicle automatically begins to adjust settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard illuminates, it serves merely as a reminder function. The Eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most vehicles employ the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the Eco mode. However, it is unnecessary to enable Eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of Eco mode but also affect the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following conditions: When the vehicle speed exceeds 120 kilometers per hour, the system prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function under these circumstances either.

What Are the Types of Vehicle Jacks?

Common vehicle jacks mainly come in two types: one is the ratchet jack, and the other is the screw jack. More information about the two types of jacks is as follows: 1. Both types of jacks are compact and space-saving, making them suitable for placement in the trunk of a car. 2. The ratchet jack has two structures: the A-frame structure and the diamond structure. (1) A-frame structure: The ratchet jack has a relatively low load-bearing capacity and is mainly equipped on small cars. (2) Diamond structure: Currently, most household cars are equipped with ratchet jacks, whose support structure is more stable and reliable than the A-frame jack. (3) Screw jack: It relies on its own threaded structure for self-locking to support the vehicle, and its load-bearing capacity is greater than that of the ratchet jack.

What to Do If the Handbrake Button Cap Falls Off?

Repair it as soon as possible, as the handbrake is crucial. Functions of the car handbrake: 1. The handbrake is used to keep the car stationary when pulled up during parking, preventing the car from rolling downhill. 3. In emergencies, the handbrake can serve as a brake. Usage of the handbrake when starting and stopping the car: 1. Starting: Press the clutch, shift to 1st gear, release the handbrake, then release the clutch and press the accelerator to start. 2. Stopping: Press the brake, stop the car, shift to neutral, and pull the handbrake tight. Correct usage of the handbrake: 1. When stuck in traffic on a slope, remember to pull the handbrake. 2. When driving at high speed, the handbrake cannot replace the foot brake. 3. Driving with the handbrake on causes significant brake wear.
