Transmission slippage symptoms: 1. When starting, pressing the accelerator causes the engine speed to increase quickly, but the vehicle speed increases slowly; 2. While driving, pressing the accelerator increases the engine speed but the vehicle speed does not improve rapidly; 3. The vehicle lacks power when climbing a slope on level ground, and the engine speed is very high. For transmissions exhibiting slippage, first check the hydraulic oil level, inspect the quality of the hydraulic oil, conduct a road test to determine if the automatic transmission is slipping, and check which gear is slipping and the extent of slippage. Causes of transmission slippage: 1. Hydraulic oil level is too low; 2. Hydraulic oil level is too high; 3. Excessive wear or burning of clutch or brake friction plates and brake bands; 4. Excessive wear of the oil pump or main oil circuit leakage, resulting in low oil pressure; 5. One-way overrunning clutch slippage; 6. Damage to the clutch or brake piston seal ring.

How to Deal with Steering Wheel Misalignment?

Methods to handle steering wheel misalignment: 1. Before parking and turning off the engine, first return the steering wheel to its original position; 2. Adjust the left and right symmetrical tie rods. The adjustment methods for right deviation and left deviation are different. When adjusting right deviation, first turn the steering wheel fully to the right, then screw the left front wheel's tie rod downward, and also twist the right front wheel's tie rod downward, aiming to make the length of the left front wheel's tie rod consistent with that of the right front wheel's tie rod; 3. Finally, tighten the nuts. Steering wheels can be categorized into single-spoke, dual-spoke, three-spoke, and four-spoke types, and their function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft.

Precautions After Applying Film to a New Car

Precautions after applying film to a new car are as follows: 1. Avoid rolling the windows up and down for three days after applying the film. 2. Do not wash the car for three days. 3. For vehicles with sunroofs, avoid opening the sunroof while driving, especially at high speeds, for three days. 4. In winter, it is recommended not to roll the windows up and down or wash the car for one week after applying the film. The front and rear films may take about a month to fully dry. During the day, the front film should be exposed to sunlight. Most importantly, do not use the rear window defroster for one month, as turning it on after applying the film in winter can cause bubbles near the heating lines, which cannot be repaired and may lead to unnecessary losses and trouble. 5. If bubbles appear at the edges of the film, visit the installation site for repairs within 24 hours. After this period, the adhesive around the bubbles will have dried, and the film edges will no longer be movable, resulting in creases during the repair process.

Can You Sleep in the Car with the Heater On?

Sleeping in the car for an extended period can lead to dizziness, nausea, and even vomiting due to oxygen deprivation, and in severe cases, carbon monoxide poisoning. Here are some precautions to take when using the heater: 1. Leave a small gap in the window to allow air exchange between the inside and outside of the car; 2. Turn on the external circulation mode when using the air conditioning to promote air exchange; 3. Regularly check the vehicle's exhaust system for leaks to prevent exhaust fumes from entering the cabin and avoid poisoning; 4. Always turn off the engine and open the windows when resting in the car; 5. A comfortable temperature inside the car is around 22 degrees Celsius; 6. Be mindful of dryness when using the heater.
