It indicates an issue with the vehicle's four-wheel drive system. 4lo is the fault indicator light for the 4WD system. Here is relevant information: 1. When this light illuminates, you must have a mechanic use a diagnostic scanner to read the trouble code and identify the cause of the fault for targeted repairs. After completing the repairs, clear the trouble codes. 2. When the vehicle switches to low-speed cruise mode in 4WD, the 4lo light flashing is a relatively common issue. The faults causing the 4lo light to flash are complex and cannot be self-diagnosed - only by reading system data can abnormalities be detected. The fault light will turn off only after the issue is resolved.

What Freebies Should You Ask for When Buying a New Car?

When purchasing a new car, the recommended freebies to ask for include: maintenance labor hour cards, maintenance vouchers, fuel cards, car window films, floor mats, mud flaps, undercoating, warning triangles, fire extinguishers, navigation systems, seat covers, rain guards, steering wheel covers, car air fresheners, and throw pillows. The proper break-in method for a new car is: 1. Warm up the engine before starting; 2. Avoid long-distance trips; 3. Choose smooth road surfaces for driving; 4. Prevent excessive vibration, impact, or emergency braking; 5. Do not remove the speed limiter prematurely; 6. Avoid maintaining a single gear for extended periods; 7. Gently press the accelerator and shift gears at low RPMs; 8. Adhere to the scheduled first maintenance date; 9. Keep engine RPMs within reasonable limits.

How to inspect the car when taking delivery?

When taking delivery of the car, the inspection methods are: 1. Check the body surface for scratches or dents; 2. Look for signs of repainting in the engine compartment and the edges under the car; 3. Check if the gaps on both sides of the doors and the front hood are symmetrical and if there are any excessively large or small gaps; 4. When opening the doors, check the coordination between the key and the lock, test if the doors open smoothly, the opening should not be too strenuous, and listen carefully for any noise from the door hinges; 5. Check if the windshield is intact and free of cracks, and also pay attention to whether the glass is original when inspecting the exterior, as there are markings at the bottom of the glass; 6. Inspect vehicle accessories such as the battery, wipers, engine oil, and other consumables to see if they are aged, and check the working condition of the chassis, wheels, shock absorbers, and suspension.

Is it necessary to replace the oil filter when changing the engine oil?

It is necessary to replace the oil filter when changing the engine oil. Here is the relevant content introduction: 1. The oil filter can filter out impurities in the engine oil flowing through the lubrication system. After the engine operates for a period of time, some impurities will be produced. These impurities mainly fall into two categories: one is metal shavings worn off from engine parts during operation, and the other is black sludge-like organic matter produced by chemical changes when the engine oil is in a high-temperature state during engine operation. These impurities will mix with the engine oil and circulate through the lubrication system. 2. The filtering performance of the oil filter will weaken over time until it fails. Road dust and high-temperature-oxidized carbides mix with moisture and enter the engine oil, and these useless substances are filtered by the oil filter.

Where Can I Inflate My Car Tires If the Pressure Is Insufficient?

You can inflate your car tires at auto repair shops or 4S stores if the tire pressure is insufficient. Here is the relevant information: Tire pressure refers to the air pressure inside the tires. The hazards of insufficient tire pressure are as follows: 1. Increases the friction coefficient with the road surface. 2. Causes the steering wheel to feel heavy and prone to deviation. 3. Increases the movement of various parts of the tire, leading to excessive rolling and abnormal heating of the tire. 4. Reduces the functionality of the cords and rubber, causing delamination or cord breakage, and excessive friction with the wheel hub, resulting in damage to the bead area. 5. May lead to tire blowouts during high-speed driving. 6. Increases the tire's contact area with the ground, accelerating wear on the tire shoulders.

Can You Make a U-Turn in a Highway Service Area?

U-turns are not allowed in highway service areas, and the entire highway prohibits U-turns. To make a U-turn, you must exit at the next interchange and then turn around. Important considerations for highway driving include: 1. Both the driver and front-seat passenger must fasten their seat belts, and the driver should not use a mobile phone; 2. Avoid sudden steering wheel movements while driving at high speeds; 3. Do not change lanes arbitrarily—always use turn signals in advance when changing lanes or overtaking; 4. Only use adjacent lanes for overtaking, and return to the original lane immediately after overtaking. Do not drive straddling or pressing against lane dividers; 5. No reversing, driving against traffic, crossing the central divider for U-turns or turns, test driving, or operating a training vehicle. Do not overtake or park on ramps; 6. Maintain a following distance of at least 100 meters. When speed is below 100 km/h, the distance can be appropriately reduced but should never be less than 50 meters.

What Causes the Steering Wheel to Shake When Braking?

The reasons for the steering wheel shaking when braking are: 1. Brake disc failure; 2. Wheel hub damage. The function of the brake is to reduce speed or bring the vehicle to a stop. Its working principle involves converting the kinetic energy of the moving vehicle into heat energy through the friction between the brake pads and the brake drum, as well as between the tires and the ground, thereby slowing down or stopping the vehicle. The causes of brake failure include: 1. Impurities in the brake master cylinder or poor sealing; 2. Failure of the vacuum booster pump; 3. Contaminated brake fluid; 4. Leakage in the brake master cylinder or wheel cylinder; 5. Air leakage from the air reservoir or pipeline connections; 6. Severe overloading; 7. Carbonization of the brake drum; 8. Insufficient brake fluid in the brake master cylinder; 9. Wear of the piston in the brake master cylinder.
