Cruise control is not useful when braking. When the driver steps on the brake, the cruise control function will automatically turn off. After activating the vehicle's cruise control and setting the desired speed, the driver no longer needs to press the accelerator pedal with their right foot, as the vehicle will automatically maintain the preset speed. Cruise control is designed to maintain a constant vehicle speed. Once the car is set to cruise mode, the engine's fuel supply is controlled by the computer, which continuously adjusts the fuel injection based on road conditions and driving resistance to keep the vehicle at the set speed without throttle input. Currently, cruise control systems have become standard equipment in mid-to-high-end cars.

What is the wading depth of the Tesla Model 3?

Tesla Model 3, although an electric vehicle, has a certain wading capability. The maximum safe wading depth for Tesla is approximately 138mm, which just submerges the chassis battery. However, the limited wading depth is not solely due to the battery. Even if the entire new energy vehicle is submerged in water, the battery will not encounter issues within 30 minutes. More relevant information is as follows: Note 1: Since the Tesla Model 3 lacks an exhaust system, it can be considered that submerging up to the chassis is the maximum wading depth. However, reaching the chassis is already the limit. If the water level rises above the chassis to the lower gaps of the doors, water will enter the cabin. Note 2: According to current standards, new energy vehicles can only ensure safety during brief wading. If a new energy vehicle remains submerged in water for an extended period, there is still a risk of spontaneous combustion. For new energy vehicles, the repair costs for the entire vehicle can be very high.

How are the Equinox and Kodiaq evaluated?

1. Body Dimensions: Both are positioned as mid-size SUVs, so there is relatively little difference in body dimensions, being at the same level overall. Specifically, the Kodiaq leads in length, width, and wheelbase, while the Equinox slightly leads in height. However, both are generally at the upper-middle level in their class. 2. Interior: The Equinox undoubtedly offers a more outstanding first impression. However, upon closer inspection, the Equinox uses a lot of hard plastics in its interior, resulting in a poorer tactile feel. Although the Kodiaq's interior may look somewhat dull, the design of its interior panels is quite stylish. 3. Powertrain: Unlike the Kodiaq, which only offers a 2.0-liter engine, the Equinox provides both 1.5 and 2.0-liter engines, both turbocharged. More impressively, the Equinox's 1.5T engine delivers 180 horsepower, only 6 horsepower less than the Kodiaq's lower-powered 2.0-liter engine. The Equinox's 2.0T engine even leads the Kodiaq by a full 40 horsepower.

What Causes a Tiguan to Suddenly Fail to Start Despite Having Fuel and Power?

Incorrect gear position. For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start the engine. If it's in R (Reverse) or D (Drive), the car won't start. Some manual transmission vehicles may also fail to start if the clutch isn't depressed. Apart from improper operation, potential causes include a faulty starter motor, fuel pump or injector issues, or sensor malfunctions. These complex situations require professional attention. Additional considerations include: 1. Fuel quality issues: During repairs, tanks have been found containing water and mud—using such fuel inevitably damages the car. Always refuel at reputable gas stations; when traveling, use a gauze over the nozzle to filter impurities. 2. Lack of antifreeze: Using water or substandard antifreeze can freeze the entire cooling system in extreme cold, cracking the engine block, disabling the water pump, preventing startup, and damaging other engine components. 3. Excessive carbon buildup: Too much carbon deposit can also prevent the car from starting. Regular highway driving helps reduce carbon accumulation.

Is Charging Free at Tesla Service Centers?

If you purchase Tesla Model S and Model X, you can enjoy unlimited free Supercharging services. As the more affordable Model 3 is more popular among users, the sales of these two more expensive models have significantly declined. Tesla may be using this service to incentivize users to purchase Model S and Model X. More relevant information is as follows: Note 1: Charging is completely free when the vehicle is being serviced at a 4S store. Another method is through the owner referral reward program. When recommending a friend to purchase a new Tesla, both the owner and the friend will each receive 1,500 kilometers of free Supercharging credit. Note 2: The mileage credit will expire 6 months after issuance. For each additional successful referral, the validity period is extended by 6 months, with a cumulative maximum of 36 months. If all mileage credits under one account are used up before the expiration date, the validity period for the next successful referral will be reset to 6 months.
