You can switch between the main and auxiliary fuel tanks using the toggle button on the driver's left control panel. Below is a detailed explanation of how to switch from the main tank to the auxiliary tank: 1. For regular vehicles: The main/auxiliary fuel tank toggle button usually features a "SUB+fuel pump" symbol. Pressing this button will switch the vehicle to the auxiliary tank, and fuel supply will then be provided by the auxiliary tank. 2. For some trucks: The main/auxiliary fuel tank toggle button in certain trucks is labeled "AUXILIARY-FUEL-TANK." Pressing this button will activate fuel supply from the auxiliary tank.

What are the reasons for the failure of the Excelle compressor?

Excelle car compressor failure is mainly due to the following reasons: Damage to the air conditioning pipeline pressure switch: When the air conditioning pipeline pressure switch is damaged, causing the pipeline pressure to be too high, the compressor load increases continuously, exceeding the transmission capacity of the belt. This leads to belt slippage, friction-generated heat, and smoke, ultimately resulting in compressor damage. Poor heat dissipation performance: If the air conditioning condenser has poor heat dissipation performance or the condenser cooling fan is faulty, it reduces heat exchange, leading to increased pressure and higher compressor load. This can cause belt slippage, friction, and smoke. It is recommended to promptly visit a 4S store or a professional auto repair shop to have a technician inspect the issue.

Where to Get Maintenance After Opel's Exit?

Maintenance will continue as before, but there will be long waits for spare parts in the future. Powertrain: The Opel Ampera uses plug-in hybrid technology, combining a 1.4L gasoline engine with an electric motor powered by lithium-ion batteries. The total output of the powertrain is 152 horsepower (111 kW), with a peak torque of 370 Nm. It accelerates from 0 to 100 km/h in about 9 seconds and has a top speed of 161 km/h. Like the Chevrolet Volt, the Opel Ampera is equipped with a 16 kWh battery, allowing for an 80 km range in pure electric mode. In hybrid mode, the maximum range extends to 500 km. Driving Modes: The Opel Ampera offers four driving modes to adapt the hybrid system to different conditions. "Normal Mode" is suitable for everyday hybrid driving. "Sport Mode" enhances driving enjoyment. "Mountain Mode" adjusts the power supply of the hybrid battery system based on terrain. "City Mode" recovers energy during braking and keeps the battery fully charged.

Should Infiniti Use 92 or 95 Octane Gasoline?

Infiniti vehicles require a minimum of 95 octane gasoline. Not recommended to switch to lower octane fuel: Under normal circumstances, it is not advisable to switch to a fuel with an octane rating lower than the standard specified in the vehicle's manual. Using lower octane fuel may cause premature combustion, leading to engine knocking. Additionally, incomplete combustion can increase carbon deposits, potentially clogging the fuel injectors and intake manifold, while also reducing engine performance and increasing fuel consumption. Follow the manufacturer's fuel recommendation: In summary, always use the fuel grade printed on the fuel filler cap or a higher grade, but never use a lower grade than recommended.

How many cylinders does the Outlander engine have?

According to the manufacturer's vehicle specifications, the new Mitsubishi Outlander is equipped with a 4-cylinder engine. Exterior Features: The front of the Outlander appears very solid, with the inverted triangular bulge on the engine hood extending down to the top of the bumper, and the front air intake is split into two sections. The slightly protruding design of the lower body gives it a full and robust look. However, compared to the original version, the modifications claimed by BAIC to suit Chinese conditions can be understood as cost-cutting measures—features like the sunroof and roof rack are missing. At the very least, the sunroof should have been offered as an optional extra. Interior Features: Sitting inside the Outlander, you experience a more spacious and comfortable feeling than in a typical sedan. Due to its higher body, the driver enjoys better visibility, and the seats provide good support, reducing fatigue. The steering wheel features a currently popular four-spoke design with tilt adjustment, but for drivers around 1.7 meters tall, this design can sometimes block the turn signal indicators on the dashboard. The circular air vents and T-shaped instrument panel echo Outlander's "unique" design philosophy, which can be considered a highlight.
