How to Use the +/- in D Gear?

Manual-automatic transmission is a type of automatic transmission that essentially adds the function of manual gear shifting. The '+' sign indicates shifting up one gear. Parking gear, starting gear. When the vehicle is parked and not in use, the gear is in this position, at which point the wheels are mechanically locked to prevent rolling. Reverse gear. Used when reversing. Neutral gear. Used when temporarily stopping the vehicle. Note that this gear position indicates neutral, and to prevent the vehicle from rolling on a slope, the brake must be engaged.

I just used this feature to deal with traffic congestion the other day. The plus and minus signs next to the D gear are actually the manual mode. When stuck in traffic, push the minus gear forward, and the transmission will lock in a lower gear, preventing the car from jerking when you release the throttle while following other vehicles. Last month, it was even more useful on mountain roads—during long downhill sections, I kept pushing the minus gear to drop to 2nd gear, using engine braking to control speed, and the brake discs didn’t even smoke. Remember, if the RPM exceeds the redline, it will automatically upshift to protect the engine, so even beginners don’t have to worry about mistakes. Want to switch back to automatic mode? Just pull it back to D gear—much more convenient than paddle shifters, and you can even operate it with barbecue sauce on your hands.

Anyone who has driven on mountain roads knows how life-saving this feature is. That time when I was driving my friend's SUV downhill, I pushed the downshift button three times in a row, and the dashboard showed M3 gear. The engine roared, slowing down the car, and I didn't touch the brakes the entire way. On the return trip climbing a steep slope, I pushed the minus button to maintain 2nd gear, keeping the RPM steady at 3000, and the car felt particularly powerful. When overtaking, quickly pressing the minus button twice in a row allowed for a smooth downshift and acceleration. Just be careful not to stay in a low gear with high RPM on flat roads for too long—when the dashboard flashes a yellow warning, it's time to upshift. After all, it's not a manual transmission; the system will automatically take over if it detects dangerous RPM levels.

I always use this function when dropping off and picking up the kids from school. Remember that steep slope at the school gate? I shift to M1 gear in advance and let the car roll down slowly, which is much more stable than braking. Once, the rear wheels slipped after a snowfall, and I immediately downshifted to use the engine's traction to get out of trouble. When queuing to pay at the supermarket basement, I shift to M2 gear to avoid the jerky feeling of frequent gear changes in automatic mode. The best part is that you don't need to remember the gear positions like with paddle shifters—the dashboard numbers turn red to remind you to upshift, which is especially friendly for middle-aged drivers. Remember, you can switch gears anytime while driving in D mode, and you can even free up your hands to take care of a child who suddenly feels sick.

Which Has More Space, Compact SUV or Small SUV?

Compact SUVs generally offer more space than small SUVs. Small SUVs typically have a vehicle length ranging between 3850-4350mm and a wheelbase of less than 2670mm. Compact SUVs, on the other hand, usually measure between 4300-4750mm in length with a wheelbase of 2600-2760mm. Compact SUVs fundamentally leverage the multi-functional carrying capacity of SUV models. Advantages of SUV models include: 1. Spaciousness: SUVs in the same class are significantly larger than sedans. Besides ample legroom, due to their body shape and higher center of gravity, SUVs provide more lateral space and headroom compared to sedans of the same class, resulting in a more comfortable ride and better visibility. 2. Superior Off-road Capability: SUVs have better off-road performance than sedans. With frequent road construction and some areas having unpaved roads, choosing an SUV helps avoid damage to the undercarriage. 3. Better Long-distance Visibility: SUV drivers sit higher, offering a more expansive view of the road ahead. 4. Practical Trunk Space: As hatchback-style vehicles, SUVs not only make it easier to access items in the trunk but also provide more usable cargo space.

Is it no longer necessary to display the annual inspection and compulsory insurance stickers?

Compulsory insurance stickers are not required in regions where electronic insurance policies have been implemented; additionally, annual inspection stickers were fully digitized in 2020 and replaced by electronic inspection certificates, so annual inspection stickers no longer need to be displayed. 1. The role of compulsory insurance: The compulsory insurance for motor vehicles primarily protects non-passengers and non-insured parties in the event of a traffic accident, providing compensation for personal injuries, deaths, and property damage within specified limits. It can also be understood as insurance that protects everyone except the vehicle owner and passengers. 2. Information on the annual inspection sticker: The motor vehicle inspection certificate includes the certificate number, vehicle license plate number, inspection agency, inspection validity period, and whether the vehicle is exempt from safety technical inspections (i.e., whether it qualifies for the six-year exemption from on-site inspections). Different motor vehicle inspection certificates come in different colors, including yellow, green, and blue.

Why Do Diesel Vehicles Need to Add Urea?

Diesel vehicles add urea to reduce exhaust emissions and protect the atmospheric environment. Urea is used to convert harmful nitrogen oxides in the exhaust into nitrogen and water. The exhaust emitted by diesel engines is highly polluting to the atmosphere. With increasingly stringent environmental regulations, exhaust treatment systems are required to ensure compliance. The primary harmful substances in diesel exhaust are nitrogen oxides and particulate matter. The exhaust treatment system helps reduce particulate emissions. Once urea is used in the vehicle, it is injected into the exhaust treatment system whenever the engine is running. Under high temperatures, urea decomposes into ammonia gas.

How to Check the Engine Oil in a Volvo S90?

Volvo S90 Engine Oil Checking Method: Enter the car status interface to view the engine oil level. Note that the oil level display is not a common progress bar but a vertical line, which requires careful observation to see clearly as it is not very obvious on the surface. The Volvo S90 is a luxury sedan under the Volvo brand. In terms of safety features, the Volvo S90 comes standard with the City Safety system, which now includes emergency braking functionality to avoid oncoming vehicles. The Pilot Assist autonomous driving assistance system provides steering support, distance keeping, and speed control assistance in slow, congested traffic conditions and on long-distance highways at speeds up to 130 km/h.

What is the maximum speed limit for trucks on highways?

On highways, the maximum speed limit for trucks must not exceed 100 kilometers per hour. Highway speed limit regulations: 1. Minimum speed: When driving normally on highways, the minimum speed for motor vehicles must not be lower than 60 km/h. 2. Two lanes in the same direction: The minimum speed for the left lane is 100 km/h. 3. Three or more lanes in the same direction: The minimum speed for the far-left lane is 110 km/h, while the middle lane has a minimum speed of 90 km/h. 4. Small passenger vehicles: The maximum speed limit for small passenger vehicles on highways must not exceed 120 km/h, while other motor vehicles must not exceed 100 km/h, and motorcycles must not exceed 80 km/h.

What to Do When the Tire Pressure Monitoring Warning Light Comes On?

The tire pressure monitoring warning light comes on should slow down the speed, find a safe place to pull over, turn off the engine, wait for 1 to 2 minutes and then restart the vehicle. After the vehicle runs stably, check the tire pressure value displayed on the dashboard. If the tire pressure light is on due to insufficient or excessive tire pressure, adjustments can be made on the spot. The appropriate tire pressure is 2.4 to 2.5 bar. You should regularly check whether the tire pressure is normal in daily life. The hazards of excessive tire pressure: 1. The friction and adhesion of the tire will be reduced, affecting the braking effect; 2. It will cause steering wheel vibration and deviation, reducing driving comfort; 3. It will accelerate the local wear of the tread pattern in the center of the tire, reducing the tire's service life; 4. The vibration of the car body will increase, indirectly affecting the service life of other components.
