Why can't the rear window of the Excelle be fully lowered?

The reason why the rear window of the Excelle cannot be fully lowered is: the window cannot be lowered all the way, leaving about one-third of the glass exposed above. This is due to design and safety considerations, as the area below the rear door is often where the wheel is located. The lower door frame is inclined or curved, resulting in an irregular shape for the lower part of the rear door. This reduces the available space compared to the front door, preventing the window from being fully lowered. The Excelle has a body length, width, and height of 4419mm, 1814mm, and 1487mm respectively, with a wheelbase of 2685mm. It features the new family-style winged chrome grille, giving the front face a sharper and more rugged appearance. The combination of black piano vertical grille and high-gloss chrome winged grille focuses the visual center of the front on the car emblem.

What are the differences between Mitsubishi Lancer and Soueast Lancer?

The main differences between Mitsubishi Lancer and Soueast Lancer lie in their manufacturers - one is domestically produced while the other is imported. Their engines are quite similar with only minor modifications in some small areas. However, both are older models with limited interior space. Below are the key differences between Mitsubishi Lancer and Soueast Lancer: 1. Difference one: There is only Soueast Lancer, which was assembled by Soueast using Mitsubishi parts. Due to technical and craftsmanship limitations, the vehicle's performance and quality were subpar, failing to fully utilize Mitsubishi engine's potential. Moreover, since the design wasn't provided by Mitsubishi, the company has never acknowledged any association between this model and the Mitsubishi brand, fearing it might damage Mitsubishi's brand reputation. 2. Difference two: Soueast once replaced its logo with Mitsubishi's to attract market attention, which angered Mitsubishi. Consequently, Soueast stopped using Mitsubishi's logo and only displayed its own emblem. However, if buyers requested, they would assist in changing the logo, as the responsibility would then lie with consumers rather than Soueast.

Where is the Passat airbag circuit board located?

The airbag control module is generally located in front of or underneath the gear shift lever. Areas marked with AIRBAG in the vehicle indicate airbag locations. Use a diagnostic tool to scan the airbag system for faults and repair according to the fault codes. If no faults are detected, the system can simply clear any existing error codes. Airbag: An airbag is a vehicle occupant restraint system that uses a rapidly inflating and deflating cushion during collisions. It consists of an airbag cushion (flexible fabric bag), inflation module, and impact sensors. The purpose of airbags is to provide soft cushioning and restraint for occupants during collision events, reducing injuries between passengers and vehicle interior components. Vehicle Airbag Locations: Airbags provide energy-absorbing surfaces between vehicle occupants and the steering wheel, dashboard, body pillars, headliner, and windshield. Modern vehicles may contain multiple airbag module configurations including: driver, passenger, curtain, seat-mounted side-impact, knee bolster, inflatable seatbelt, front right-side, left-side sensors, and pedestrian airbag modules.

What does eco-smart mode mean?

Eco-smart refers to the energy-saving driving mode of a vehicle. It primarily involves comprehensive judgment and analysis of various factors affecting fuel consumption during vehicle movement, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The eco control unit calculates the optimal fuel quantity to be supplied to the engine for operation, effectively reducing fuel consumption compared to normal driving mode. The term 'eco' is derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). 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. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type 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 adjusting 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 dashboard eco indicator light 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 always activate the eco mode. Additionally, the eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the vehicle prioritizes speed, and the eco mode automatically deactivates. When the vehicle is idling or in N/P gear or manual mode, the eco mode may also deactivate. When high torque output is required, such as when climbing a slope, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the eco mode will not function under these conditions either.

Can the BMW X1 use 92 octane gasoline?

According to the official vehicle manual recommendation, the BMW X1 should use 95 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, you can also find it marked on the fuel tank cap of the BMW X1. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should choose 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should opt for 95 octane gasoline. However, with the application of some new technologies nowadays, the gasoline grade cannot be solely determined by the compression ratio. A high compression ratio can also be adjusted to use lower octane gasoline. This is because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane number, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the BMW X1 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended for low octane gasoline, using high octane gasoline will not cause damage, but the increase in octane value will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance as experienced by the driver. For vehicles recommended for high octane gasoline, using low octane gasoline can cause engine knocking. Due to the significantly lower octane value, the reduced ignition point of the gasoline may cause premature ignition during the compression stroke. If combustion occurs before the spark plug ignites during the compression stroke, resistance will arise during the upward stroke. This resistance can make the engine run very unstably. If the knocking is imperceptible, it may only increase noise without obvious damage to the engine. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear to pistons and cylinders, and in severe cases, cylinder scoring.

What is the speed range for third gear in a car?

Third gear corresponds to a speed range of 20-40 km/h. Generally, the optimal shifting point for most cars is when the engine reaches 2000 r/min, preferably not exceeding 2500 r/min. For high-displacement or high-power engines, the maximum efficiency range may extend further, so shifting around 3000 r/min can be considered. Different vehicles have varying engine and transmission performances. Drivers can identify the shifting point by listening to the engine sound. Typically, a dull engine sound indicates it's time to upshift. Driving in a lower gear at this point increases engine pressure, fuel consumption, and negatively impacts both the engine and transmission. Additionally, downshifting should be considered when the engine speed drops below around 1500 r/min. Upshifting timing: When the engine has ample power, it produces a dull humming sound. After upshifting, if there is no power deficiency or drivetrain vibration, and the vehicle accelerates smoothly and naturally, it indicates the upshifting timing is accurate. Downshifting timing: When both vehicle speed and engine speed continuously decrease, and the car feels sluggish with noticeable engine compartment vibration, it's time to downshift one gear. Downshifting too early will cause a noticeable jerk, wasting power and increasing fuel consumption while also affecting the engine and transmission lifespan. Downshifting too late will result in continued power deficiency even after shifting down, leading to persistent jerking. Misjudging the shifting timing will cause such irreparable consequences, inevitably affecting the driving experience.
