What are the benefits of using high-octane gasoline?

Using high-octane gasoline has no benefits, and here are the reasons: 1. If you use high-octane gasoline when low-octane gasoline should be used, it may lead to insufficient compression ratio, resulting in incomplete combustion, sluggish acceleration, and delayed ignition. 2. The octane number of gasoline refers to its anti-knock performance; the higher the octane number, the better the anti-knock performance. 3. Manufacturers have already preset parameters such as the engine's compression ratio and ignition timing in the vehicle's computer. The appropriate octane level for a car should be determined based on the manufacturer's specifications.

How to turn off the rear wiper on a BMW X5?

Lifting the wiper control lever upwards sprays washer fluid to clean the front windshield, while pressing it downwards activates the rear wiper; resetting it stops the rear wiper. More related information is as follows: 1. The rear wiper can be activated by moving the wiper lever forwards or backwards, which differs from the up-and-down operation of the front wiper switch. Moving the lever forwards or backwards controls the rear wiper's on/off function, intermittent operation, automatic mode, and washer fluid spray. 2. It is generally recommended to replace the wipers once a year. However, if the wipers are still effective and show no signs of aging, the replacement interval can be extended. The most important factor is the condition of the wipers themselves. If they show signs of ineffective cleaning within less than a year, they should be replaced. 3. Wiper maintenance mainly involves keeping the wiper blades clean, avoiding excessive dirt or debris on the rubber strips. If debris is trapped in the wipers, they will not clean effectively, accelerate the aging of the rubber strips, and potentially scratch the windshield. The correct approach is to remove any debris or dirt from the wiper rubber strips during each car wash or periodically. It is best to rinse with water first, then wipe the wiper strips with a cotton cloth or tissue. This ensures effective cleaning and extends the wipers' lifespan.

What does the +- next to the automatic transmission mean?

Automatic transmission's +- refers to gear shifting. Generally, there is an "M" letter next to the +-, which is the abbreviation of the English word "manual". "+" means upshift, representing a manual upshift, similar to the fourth and fifth gears in manual transmission vehicles; "-" means downshift, similar to the first and second gears in manual transmission vehicles, which is more suitable for uphill and downhill driving. When the vehicle is in manual mode, the transmission cannot shift gears automatically and remains in a fixed gear for driving. It will only upshift when the engine speed exceeds the limit of 6000 rpm, and downshift when the engine speed is below 1200-1400 rpm. Manual mode switching method: For an automatic manual transmission, the driver first presses the brake and pulls the gear lever down to the "D" gear, then pushes the gear lever to the left or right (some vehicles require a direct downward pull). At this time, the dashboard will display the "M" gear, and the vehicle enters manual mode.
