What to Do When a Vehicle Stalls in Water

There are several scenarios when a vehicle encounters water: 1. Water enters the engine cylinders through the intake system. 2. Water enters the exhaust pipe. 3. The electrical system shorts due to water immersion. Key driving techniques when passing through waterlogged areas are: 1. Use high torque and low speed. Pass through waterlogged areas in first gear with moderate throttle (for automatic transmission vehicles, use L gear or first gear). Do not attempt to pass if the water level exceeds the lower edge of the bumper, as the vehicle's movement may create waves, allowing water to easily enter the engine cylinders through the intake system. Since water is incompressible, if it enters the engine cylinders during operation, the compressed water can generate tremendous counterforce, leading to connecting rod fractures, crankshaft deformation, or even engine block rupture. 2. If the engine speed is too low when passing through water, water may enter the exhaust pipe, causing poor exhaust flow and stalling. In this case, do not attempt to restart the engine. Immediately call for towing assistance, as water may have entered the engine cylinders. Forcing the engine to run could cause more severe damage. If the vehicle is submerged while parked, note the following: 1. First, assess the water level. If the water is about half the tire height, the engine is likely not affected. After the water recedes, start the vehicle and drive to a repair shop for chassis or exhaust pipe cleaning. 2. If the water exceeds half the tire height, both the engine compartment and passenger cabin may be flooded, potentially causing electrical system shorts. Do not start the engine. Wait for the water to recede and have the vehicle towed to a repair shop. Attempting to start the vehicle could result in serious damage.

Where to Place the ETC Tag?

The ETC installation position for passenger cars is generally in the upper middle section of the front windshield, while for large vehicles like trucks and buses, it is installed in the lower middle section. The appropriate installation position should be at a height no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic Toll Collection. To apply for ETC, the vehicle owner needs to provide original and photocopied versions of their valid ID card and vehicle registration certificate. If the application is handled by a non-owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed, and the vehicle must be registered under an individual aged between 18 and 60. Here are some precautions for ETC installation: Do not obstruct the driver's view. The best position is behind the rearview mirror: Many car models have windshields with a steep rearward angle, which can reduce the driver's field of vision. Installing the ETC without considering this may increase blind spots. Installing it on the right side behind the rearview mirror can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove the tag arbitrarily once installed: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing a single device. ETC usage tips: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle in front due to its faulty ETC device, maintain a distance of at least 10 meters from the vehicle ahead. The ETC lane recognizes vehicles at a speed of 20 km/h; driving too fast may result in failed fee deduction due to inability to read the vehicle's device information. When using a debit card linked to ETC, insufficient balance may also cause fee deduction failure.

What is needed for the first car maintenance?

Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; vehicle purchase invoice, to be taken to the designated first maintenance facility for the vehicle's initial service. Important note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after a new car has been driven, with the specific timing varying by vehicle, generally around 5,000 kilometers or six months. It is crucial to attend the first maintenance on time, neither early nor delayed. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven under standard load and normal speeds as required by the vehicle. The timing for the first maintenance is calculated from the date of vehicle pickup, with two indicator values: mileage and time. Whichever comes first serves as the standard. The first maintenance includes: oil change, oil filter replacement, cleaning the air filter, checking various fluid levels, inspecting the generator belt and wiper blades for damage, checking tire pressure, and examining tires for damage or bulges. Estimated time required: Approximately 2 hours to complete all tasks. The most critical aspects of a new car's first maintenance are the oil and oil filter change. When changing the oil, the oil filter must also be replaced. The choice of oil must refer to the "Vehicle Usage and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car body with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It is important to note that the interior should not be directly washed with water. If floor mats are dirty, use a vacuum cleaner or remove them to brush with detergent, dry, and then replace. The rubber mats under the driver's floor have many drainage holes. Water entering these areas will not dry but flow through the holes to corrode components like the gearbox. The best practice is to vacuum clean and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the car's antifreeze is low, it is recommended to drain the existing antifreeze and refill with the same brand from the start. Different brands of antifreeze have varying chemical properties, and mixing them can lead to corrosion due to incompatible inhibitors. Avoid mixing brands to prevent unnecessary issues. Do not lubricate wheel bolts and nuts: When bolts on a moving car rust, they are often oiled to function again. However, applying lubricant to wheel bolts and nuts can pose safety risks. At high speeds, bolts and nuts may loosen or even fall off, leading to driving hazards. Do not press the accelerator when starting an EFI (Electronic Fuel Injection) car: EFI cars differ from conventional vehicles, as their fuel injection control system can automatically adjust fuel supply based on the engine's temperature and operating conditions, ensuring smooth starting.

How to Turn on the Tesla Heater?

After starting the vehicle, wait for 5-10 minutes until the water temperature rises to the normal level, then you can turn on the heater. Adjust the car's air conditioning circulation mode to internal circulation to help the cabin heat up quickly. Later, switching to external circulation as needed will help with air circulation inside the cabin. When the heater is turned on, the fan will operate, slightly increasing fuel consumption. Do not press the AC button. Adjust the air conditioning to a suitable setting and direct the airflow as desired. Maintain the cabin's temperature, humidity, and cleanliness at optimal levels.

What to Do When Lithium Battery Range Decreases?

Compared to summer, the resistance increases in winter. To achieve the same power output, the current must be increased, making the battery appear to deplete faster. The internal resistance of lithium-ion batteries is related to temperature. The lower the temperature, the higher the internal resistance, which is why battery consumption is particularly rapid in winter. In summer, the maximum charging time can reach up to 12 hours. However, in winter, it is best not to exceed 8 hours, with 6 hours being optimal to avoid the risk of battery swelling. Gradual acceleration is recommended to maximize battery range and durability.
