Automatic transmission car's gear shift plus and minus signs refer to the manual mode of the automatic transmission. The plus sign is for manually upshifting, and the minus sign is for downshifting. The method to use manual mode is: 1. Shift the gear to D, then push the gear lever to the right, and the transmission enters sport mode; 2. Use the method of pushing the gear lever forward and backward to shift gears, pushing forward to upshift and pushing backward to downshift; 3. To switch back to automatic mode, simply push the gear lever to the left to the D position. The gears of an automatic transmission car are: 1. P is for parking and starting; 2. R is for reverse; 3. N is for neutral; 4. D is for drive, also known as forward gear; 5. L is for low gear; 6. S is for sport mode; 7. OD is for overdrive.

I saw a friend asking about the plus and minus signs on the automatic transmission gear shift. I've been driving an automatic for years, and these are for the manual shift mode. The plus sign is for upshifting, which can lower the engine RPM on flat roads or highways for better fuel efficiency; the minus sign is for downshifting, providing more torque when climbing steep hills to prevent rolling back or assisting with braking when going downhill. Once, I used downshifting to control speed on a mountain road, which was much safer than just relying on the brakes. It gives you extra control freedom, but you generally don't need to use it in daily driving—only in specific scenarios. I recommend practicing with it a few times when you get a new car to get familiar with the feel, otherwise, it might feel awkward when you suddenly need to use it.

As a car enthusiast, I can explain the meaning of the plus and minus signs: they are symbols that simulate manual shifting. When the automatic transmission is set to manual mode, the plus sign is used to upshift and reduce engine speed, typically for fuel-efficient cruising; the minus sign is used to downshift and increase engine speed, suitable for overtaking or overcoming resistance. The engine control unit will manage gear changes based on vehicle speed to protect the transmission. Normally, it operates automatically in city driving, but manual intervention can enhance performance when climbing hills or tackling tough road conditions. Remember to maintain reasonable RPM during operation—don't force an upshift at low RPM to avoid engine lugging.

How to Start a Geely Car When the Battery is Dead?

You can either charge the car battery before starting or call for a rescue vehicle to jump-start it. Here are some precautions regarding car batteries: 1. Check the Battery Cover: Regularly check if the small holes on the battery cover are ventilated during daily driving. If these holes are blocked, the generated hydrogen and oxygen cannot escape, and when the electrolyte expands, it may rupture the battery casing, affecting the battery's lifespan. The typical lifespan of a car battery is around two years. 2. Replenish Power in Time: If the car is left unused for an extended period, start it periodically to recharge the battery to prevent it from becoming unusable due to prolonged power loss. Continuously using the starter when starting the car can damage the battery due to excessive discharge. The correct method is to limit each starting attempt to no more than 5 seconds, with intervals of at least 15 seconds between attempts.

What is the Definition of Lane Change Completion?

A lane change is considered complete when the vehicle inevitably deviates and crosses the original lane divider, then adjusts its direction to proceed along the new lane, establishing a state of driving along the new lane. Below are precautions for lane changing: Avoid the habitual release of the accelerator during a lane change, which may cause gear disengagement; Yield to vehicles in the lane you are entering; Do not change more than two lanes at once; When vehicles from both the left and right lanes are changing into the same lane, the vehicle on the left must yield to the one on the right. Below are the evaluation criteria for lane changing in Subject 3 of the driving test: 1. Before changing lanes: Failing to observe the traffic conditions behind through the interior and exterior rearview mirrors results in disqualification. 2. During the lane change: If the judgment of the vehicle's safe distance is unreasonable and hinders the normal driving of other vehicles, it results in disqualification. 3. Turn signal usage: Failing to use or incorrectly using the turn signal before changing lanes deducts 10 points. Turning the steering wheel less than 3 seconds after activating the turn signal before changing lanes deducts 10 points.

What Causes the ABS and Exclamation Mark Lights to Illuminate?

ABS light can illuminate in various states, with different causes and solutions for each state. The details are as follows: State 1: ABS warning light stays on (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the contaminants from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections between system wires or poor contact of the ABS relay, leading to system malfunction. Solution: Check wire connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases and voltage rises, the ABS light turns off. This can also occur if the ABS system's power supply voltage is too low, such as due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact of the ABS hydraulic valve body; poor contact of the ABS hydraulic valve body wire connector; ABS computer malfunction. Solution: Loosen and retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact of the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete self-positioning; replace the brake light switch if necessary. If the ABS warning light is on, it is advised not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's path, posing significant safety risks.

Is it necessary to have a car driver's license for one year before applying for a motorcycle driver's license?

If you have just obtained a driver's license, you must wait until the one-year probation period is over before applying for an additional license. Additionally, there should be no record of accumulating 12 penalty points in the current scoring cycle or the one before applying. If you do not have a driver's license and wish to apply for a motorcycle driver's license, you can register at the local traffic police vehicle management office. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," motorcycle driver's licenses are divided into three types: D, E, and F. Among them, D is for ordinary three-wheeled motorcycles, E is for ordinary two-wheeled motorcycles, and F is for light motorcycles. Upgrading from a C1 license to a motorcycle license requires passing four subjects, and the examination process is the same as directly applying for a motorcycle license. The examination subjects are as follows: Subject 1: Examination on road traffic safety laws, regulations, and related knowledge. Subject 2: Field skills test, including pile test, slope fixed-point parking and starting, and passing a single-plank bridge. Subject 3: The content of Subject 3 is determined by the provincial public security traffic management department, and there is no unified standard. Subject 4: Examination on the requirements of safe and civilized driving, safe driving skills under complex conditions, and emergency response knowledge.

How Many Liters of Engine Oil Does a Cruze Need?

The Chevrolet Cruze requires approximately 4 liters of engine oil. The recommended oil type is 5W30. During maintenance, ensure not to overfill or underfill the oil, as this can negatively impact the engine. For oil brands, you can choose from options like Mobil, Shell, or Castrol. Engine oil viscosity changes with temperature, so it's crucial to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means the oil can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the vehicle. The latter number represents the oil's kinematic viscosity at 100°C. A higher value indicates better viscosity retention under high temperatures, which can also be interpreted as superior lubrication performance in high-temperature conditions. When selecting engine oil, keep the following points in mind: Choose oil based on the engine's requirements. It's unnecessary to use overly advanced oil in engines with lower requirements, and similarly, lower-grade oil should not be used in high-demand engines. Opt for multigrade oil whenever possible. Multigrade oils are economical, have a long lifespan, and are highly efficient, offering better protection for the engine. Due to their characteristics, multigrade oils may appear darker prematurely and exhibit lower oil pressure compared to conventional oils, both of which are normal.
