Why does the tire pressure warning light still appear after replacing with a spare tire?

After replacing with a spare tire, the tire pressure warning light may still appear generally because the spare tire is underinflated or the tire pressure system hasn't been reset. If no visible damage is found, simply inflate the tire to normal pressure and reset the tire pressure monitoring system. If inspection reveals the spare tire has been punctured, drive promptly to a tire shop for repair, then reinflate it. If the low pressure warning reappears after inflation without any puncture, it might be caused by air leakage due to wheel rim deformation. It's recommended to check the wheel rim and replace if necessary. Low tire pressure can cause heavy steering, vehicle drift and other factors detrimental to driving safety. It also reduces the functionality of tire cords and rubber, leading to delamination or cord breakage, causing excessive friction between the tire and rim which damages the bead area and causes abnormal wear. Moreover, friction between the tire and road surface increases exponentially, causing rapid temperature rise that softens the tire and drastically reduces its strength. This may lead to tire blowouts during high-speed driving.

What is the 0-100 km/h acceleration time of the Reiz?

According to official data, the Reiz is available in two engine displacements: 2.5L and 3.0L. The 2.5L model accelerates from 0-100 km/h in 9 seconds, while the 3.0L model takes 9.1 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time include: Torque: Torque, in simple terms, represents the strength of the force. The greater the torque, the stronger the force pushing the vehicle, resulting in faster acceleration. The Reiz 2.5L has a maximum torque of 236 Nm and accelerates from 0-100 km/h in 9 seconds. In comparison, the LaCrosse has a torque of 250 Nm but takes 9.6 seconds for the same acceleration. Transmission efficiency: The transmission acts as a medium for power transfer, inevitably involving power loss. Higher transmission efficiency leads to better acceleration performance. Generally, transmission efficiency ranks as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Reiz is equipped with a 6-speed automatic transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is called the power-to-weight ratio (unit: Hp/T). A higher power-to-weight ratio results in faster acceleration. The Reiz 2.5L has a power-to-weight ratio of 126.97 Hp/T and accelerates from 0-100 km/h in 9 seconds. The LaCrosse has a power-to-weight ratio of 110 kg/PS and takes 9.6 seconds for the same acceleration.

What is the fuel consumption per kilometer for the Changan Oshan X7?

Changan Oshan X7 has a total of 9 models. Among them, the 2021 1.5T manual Luxury, Comfort, and Elite models are equipped with a 178 horsepower engine, consuming 0.07L per kilometer. The 2021 1.5T automatic Navigation, Geeker, and Premium models, among six others, are equipped with a 178 horsepower engine, consuming 0.074L per kilometer. The fuel tank capacity of the Changan Oshan X7 is 55L. The distance each model can travel on a full tank is as follows: 2021 1.5T manual Luxury, Comfort, and Elite models can travel 55/0.07=785km on a full tank. 2021 1.5T automatic Navigation, Geeker, and Premium models, among six others, can travel 55/0.074=743km on a full tank. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger displacement generally consume more fuel than those with smaller displacement because larger displacement usually means higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperature: When the engine block is cold, the injected gasoline does not atomize easily, requiring more gasoline to burn, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer controls higher RPMs to warm up the car, which also increases fuel consumption.

What are the precautions for picking up a car?

Precautions for picking up a car: 1. Body paint surface: Mainly inspect the external paint surface of the car body. Park the car in a well-lit area, walk around the car, and check whether the paint color is uniform, and whether there are any bulges, scratches, etc. If necessary, you can also touch it with your hand. 2. Window glass: Check all the glass for damage and scratches, with a focus on the visual effect of the front windshield. The front windshield must have good light transmittance and should not have bubbles or areas with abnormal refractive index. 3. Tire inspection: When checking the tires, look at whether the tire tread is clean, whether there are scratches on the wheel rim surface, and whether the tire burrs are excessively worn (short-distance driving generally causes less wear to the tire burrs). If necessary, also check whether the tire pressure is normal. 4. Engine inspection: Open the hood, check the manufacturing date, see if all parts of the engine are clean, especially in the nooks and crannies (these areas in used cars can easily accumulate dirt and are hard to clean). Then pull out the dipstick to check the oil level and cleanliness. 5. Chassis inspection: If conditions permit, drive the car into the warehouse and use a lift to check whether there are any scratches or dents on the chassis, and whether there are any obviously unreasonable parts in the pipelines.

How to Use the S Gear in Corolla Hybrid?

To engage the S gear in the Corolla Hybrid, simply press and hold the lock button while pulling the gear lever into the S position. The vehicle is also equipped with paddle shifters on the steering wheel. In S gear, you can manually switch between 6 gears using the paddle shifters. This manual mode differs slightly from the manual control transmission shifting found in conventional gasoline engine models. The primary function of the manual mode is engine-assisted braking, providing additional energy recovery during long downhill drives and similar conditions. Below are some related details: 1. It's important to note that the S gear in the Corolla Hybrid is not a sport mode; instead, it is a forced kinetic energy recovery mode, which enhances fuel efficiency. The S gear is not a single position but ranges from S1 to S6, with varying levels of braking force from strong to weak. Additionally, the braking force is partially recovered, so simply releasing the throttle in S gear will generate braking force. 2. During normal driving, after shifting to D gear, you can directly switch to S gear by moving the gear lever without any additional steps. To switch, move the lever to the right and then downward to engage S gear. You can shift directly from D gear to S gear, but you cannot shift directly from N gear to S gear. Similarly, you can shift directly from S gear back to N gear.

What do 4H and 4L mean in cars?

4L stands for four-wheel drive low gear mode, which provides high torque for tackling complex road conditions such as climbing slopes or off-roading. 4H stands for four-wheel drive full gear mode, used for normal driving with powerful performance and top-notch handling, but it consumes more fuel than 2H mode. Below is more information about 4H and 4L in cars: 1. 4H and 4L are two modes available in four-wheel drive vehicles. 4H is the four-wheel drive high-speed mode, while 4L is the four-wheel drive low-speed mode. These two drive modes differ in terms of transmission control and are used in different scenarios. Properly utilizing the four-wheel drive mode based on terrain can not only improve the vehicle's off-road capability but also reduce fuel consumption to some extent. 2. The 4H mode is ideal for driving on snowy or slippery roads, as it ensures sufficient drive wheels while avoiding excessive driving force that could cause wheel slippage. The 4L mode, with its high driving force, is not suitable for such conditions but can be used when climbing steep slopes or off-roading to maximize the vehicle's power. 3. High-speed four-wheel drive (4H) is not suitable for highway driving. For part-time four-wheel drive vehicles, dry paved roads are not appropriate for 4H or 4L modes; only 2H mode should be selected. 4. The full name of 4H is 4WD-HIGH, where the gear ratio in the transfer case is smaller, allowing the vehicle to maintain high-speed movement. The full name of 4L is 4WD-LOW, where the gear ratio in the transfer case is larger, maximizing torque but limiting speed. This mode is typically used for extremely harsh road conditions.
