Is the spare tire the same as the original tire?

Spare tires are not the same as original tires. The differences between spare tires and original tires are as follows: The diameter and width of a car's spare tire are slightly smaller than those of the original tire, and most spare tires are not full-size tires. Prolonged use can affect driving safety. Original tires are perfectly matched to the vehicle and are suitable for long-distance driving. Precautions for using spare tires: 1. Adjust the tire pressure when using a spare tire; 2. Spare tires should not be used for an extended period; 3. Spare tires should not be involved in tire rotation; 4. The lifespan of a spare tire is about 4 years; 5. Regularly inspect the spare tire. Additionally, oil products should not be stored together with spare tires. The main component of tires is rubber, which can easily be eroded when mixed with oil products. If oil comes into contact with the tire, it should be rinsed off promptly.

The spare tire is completely different from the original tire in most cases, as I discovered when I changed a tire myself before. The original tire is designed for daily driving, with the exact size matching your car model, providing smooth handling and grip. What about the spare tire? It's often a temporary solution, smaller in size, like those narrow and flat T-type spare tires, with rims prone to rust and made of cheaper materials. Manufacturers do this to save costs and trunk space, but it poses several risks for users: you can't drive too fast, usually limited to below 80 km/h, and it's only meant for short distances, like within 50 km, otherwise it could damage the suspension system. The spare tire also has weaker load-bearing capacity; if overloaded, it might blow out. Spare tires generally have a shorter lifespan and can age and crack if left unused for several years without replacement. My advice is to replace the spare with the original tire at a repair shop as soon as possible after an emergency, keep the spare tire properly inflated, and check it monthly for safety.

What type of engine oil is suitable for the Haval H5?

Haval H5 is suitable for fully synthetic engine oil. There are three types of engine oils used in vehicles: mineral oil, fully synthetic oil, and semi-synthetic oil. Different engine types require different types of engine oil. Compared to semi-synthetic and mineral oils, fully synthetic oil offers better performance and a longer service life. The Haval H5 is a compact SUV launched by Haval. The dimensions of this vehicle are 4645mm in length, 1800mm in width, and 1775mm in height, with a wheelbase of 2700mm. The front face features a new hexagonal grille with horizontal chrome accents, and the headlights on both sides adopt a new wing-shaped design, integrated with LED daytime running lights, giving the front face a higher level of recognition.

Where is the clutch and brake located?

The clutch is the first pedal from left to right, and the brake is the second pedal from left to right; manual transmission cars have three pedals, arranged from left to right as the clutch pedal, brake pedal, and accelerator pedal. Normally, the left foot controls the clutch, while the right foot controls the brake and accelerator. The clutch pedal is used to engage and disengage to transmit an appropriate amount of power. The clutch consists of friction plates, spring plates, pressure plates, and a power output shaft, and is located between the engine and the transmission. It transmits the torque stored on the engine flywheel to the transmission, ensuring that the vehicle delivers the appropriate driving force and torque to the drive wheels under different driving conditions, falling under the category of the powertrain.

What does the AVH Auto Hold System mean

Auto Hold refers to an automatic braking function. After activating this feature, such as when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of manual or electronic parking brakes. For automatic transmission models, it also reduces the need for frequent shifting between D to N or D to P. The functions of the Auto Hold system include: 1. Preventing rollback: When stopping briefly at a traffic light, the system automatically applies the brakes to the wheels after the vehicle comes to a complete stop to prevent rolling. 2. Preventing backward sliding: During uphill starts, the system automatically brakes to prevent backward sliding, and releases the wheels automatically when starting to move forward. 3. Automatic braking: Some models automatically apply the brakes to the wheels when the vehicle is parked and locked, eliminating the need to pull the handbrake. Working principle of Auto Hold: When the vehicle is temporarily stopped and needs to restart shortly after, the parking function is handled by the ESP-controlled brakes. The computer uses a series of sensors to measure the vehicle's levelness and wheel torque, determines any tendency for the vehicle to move, and applies an appropriate braking force to the wheels to keep the vehicle stationary. This braking force is just enough to prevent movement without being excessive, ensuring a smooth start when the accelerator is pressed again. If the temporary stop exceeds a certain duration, the braking system switches to mechanical rear-wheel parking (activating the electronic parking brake) instead of the previous four-wheel hydraulic braking. When the vehicle is ready to move forward, the electronic system detects the accelerator pedal pressure and, for manual transmission models, the clutch pedal travel to determine whether to release the brakes.

Where is the cabin air filter located in the old Mazda 3?

The cabin air filter in the old Mazda 3 is located beneath the glove compartment on the passenger side, and the fuse box needs to be removed for access. The old Mazda 3 is a model series under Changan Mazda, available in two variants: a 5-door hatchback and a 4-door sedan. The domestic version is equipped with a 1.6-liter gasoline engine. The old Mazda 3 features advanced safety systems similar to other models in the Mazda family, including HBC (High Beam Control) automatic headlight system, AFS (Adaptive Front-lighting System) active headlights, HLA (Hill Launch Assist) hill start assist, ESS (Emergency Stop Signal) emergency brake alert system, RVM (Rear Vehicle Monitoring) blind spot detection, and LDWS (Lane Departure Warning System) lane departure warning.

How to Handle a Car That Hasn't Been Driven for a Long Time?

Methods for handling a car that hasn't been driven for a long time: 1. Thoroughly clean the car's paint and interior before parking to prevent damage to the paint during storage. After cleaning, it is recommended to wax the car for better protection; 2. Remove the car battery to maintain sufficient charge; 3. Protect the tires. If the car remains stationary for a long time, the part of the tires in contact with the ground may deform or lose air. The owner should move the vehicle or drive it for a while; 4. Check the fluids. Cars have various fluids, and if the vehicle is parked for an extended period, it's necessary to inspect the condition of all fluids and replace them in time to prevent deterioration; 5. Find a suitable parking spot, cover the car with a car cover to properly protect the paint.

What are the symptoms of a broken engine turbocharger?

Symptoms of a broken engine turbocharger: The car's exhaust pipe emits blue or white smoke, decreased power, increased fuel consumption, increased engine oil, and unstable turbo pressure. When the car is idling, the exhaust pipe emits blue or white smoke due to poor sealing of the turbocharger impeller shaft. When the turbocharger malfunctions, the car's power will noticeably decrease, and fuel consumption will rise accordingly. If the exhaust gas recirculation pipe is blocked, stepping on the accelerator will not only produce blue smoke but also accelerate engine oil consumption. It is important to note that after starting the engine, you should not drive immediately. Instead, let the engine idle for 2 to 3 minutes to allow the turbocharger to be fully lubricated before driving. During long-distance driving, if the engine has been running at high speed for an extended period, do not turn it off immediately. Sudden shutdown can cause the residual oil in the turbocharger to overheat and damage the bearings.
