How to Set Up Car Alarm?

Car alarm setup instructions are as follows: 1. Speed limit alarm setting: Use the up and down keys on the right lever to navigate to -/KM/H, then press the button on the lower right of the right lever for about 3 seconds. —— starts flashing, adjust to your desired number using the up and down keys. 2. Anti-theft alarm setting: The vehicle itself comes with an anti-theft function, so when locked, the vehicle's anti-theft function will automatically activate. When the vehicle experiences vibration, it will emit an alarm sound, and the hazard lights will automatically turn on. Vehicle alarm sensitivity adjustment instructions are as follows: 1. Unlock the vehicle and enter, then press and hold the unlock button on the key for 5 seconds until the turn signals stay on. 2. This indicates that the vehicle has entered the alarm sensitivity setup program. Then, without pressing the brake, press the one-touch start button. 3. Sensitivity is divided into five levels, with level one being the lowest and level five the highest. Each press of the start button increases the sensitivity by one level.

What are the solutions for timing belt noise?

Here are the solutions for timing belt noise: 1. Identify the cause of abnormal noise: When abnormal noise is detected from the timing belt, first determine whether the noise is caused by the belt itself or by damage to the timing belt tensioner or idler pulley. 2. Belt cracking: Open the cover of the timing belt to expose the belt and pour water on it. If the noise disappears or significantly decreases, it can be confirmed that the noise is from the timing belt. Inspect both sides of the timing belt for fine cracks. If the mileage exceeds 60,000 kilometers and cracks are present, replace the timing belt directly. If the mileage is low and there are no signs of cracking, adjust the belt tensioner to tighten the belt. 3. Pulley noise: If noise persists after pouring water on the belt, the noise is not from the belt. Remove the outer cover of the belt and use a stethoscope to check if the noise is from the belt tensioner or idler pulley. The pulleys have bearings that are prone to damage and noise. Replace the problematic pulley.

Is it serious to have engine oil in the intercooler?

Generally, it is not serious to have engine oil in the intercooler, but it needs to be analyzed based on specific conditions. The following are the reasons for engine oil in the intercooler intake pipe: 1. Internal reasons: prolonged engine idling, clogged or deformed crankcase ventilation system, and coking of lubricating oil in the turbocharger intermediate housing. 2. External reasons: driving conditions and maintenance can cause engine oil to enter the intercooler intake pipe. Below is an introduction to the intercooler: 1. Function: The intercooler's role is to reduce the intake air temperature of the engine. The exhaust gas from the engine is very hot, and the heat conduction from the turbocharger increases the intake air temperature. As air is compressed, its density increases, but this also raises the temperature of the air discharged by the turbocharger. While air pressure increases, oxygen density decreases, thereby affecting the engine's effective charging efficiency. 2. Classification: Intercoolers are usually made of aluminum alloy. Based on the cooling medium, common intercoolers can be divided into two types: air-cooled and water-cooled.

What is the Difference Between Discounted Cars and New Cars?

Here are the differences between discounted cars and new cars: 1. Price: As the name suggests, discounted cars have special prices, often due to manufacturer promotions to attract customers or the launch of new models or updated versions. 2. Sales period: Clearing inventory generally refers to cars that have remained unsold for over three months by the manufacturer, which can then be sold as discounted cars. 3. Quality: New cars come with quality guarantees and are the latest models, providing owners with high-quality after-sales service. Below is additional information about the main items covered in a new car's first maintenance: 1. Engine oil: Replace the engine oil and oil filter. 2. Brake system: Inspect the operation of the brake system. 3. Drive belts: Tighten bolts across various systems and inspect and adjust the drive belts. 4. Tires: Inspect and adjust tire balance and alignment. 5. Inspection: Check and top up various fluids, and inspect the operation of components such as lights, the battery, and shock absorbers.

How to Solve Parking Brake Failure?

To address parking brake failure, it is essential to first identify the cause of the issue before proceeding with repairs. Below are specific reasons for different parking brake failures: 1. Unusual Noises: If knocking sounds are heard from the parking brake while driving, stop the vehicle and inspect it. Check for loose fastening screws, control levers, or fixing pins, and adjust or repair them promptly. 2. Parking Brake Lever Not Staying Fixed: When using the parking brake, if the lever does not stay in the braking position, first release the lever head and check if the lever is bent, stuck, or if the spring is broken. 3. Parking Brake Malfunction: For this issue, inspect whether the gap between the friction pads and the brake drum is too large, if there is oil contamination or severe wear on the friction pads and brake drum, exposed rivets, or surface hardening, which may cause the malfunction.

Is the Roewe e950 a plug-in hybrid?

Roewe e950 is a plug-in hybrid. Plug-in hybrid electric vehicles (PHEVs) are a type of new energy vehicle that bridges the gap between pure electric vehicles and conventional fuel-powered cars. They incorporate both the traditional car components such as engine, transmission, drivetrain, fuel system, and fuel tank, as well as the electric vehicle components including battery, electric motor, and control circuitry. The Roewe e950 is equipped with a 1.4-liter turbocharged engine delivering a maximum power of 112 kW and peak torque of 235 N·m, with maximum power achieved at 5,600 rpm and maximum torque available between 1,600 to 4,000 rpm. The electric motor paired with it produces a total power output of 56 kW and maximum torque of 318 N·m. The vehicle dimensions measure 4,996 mm in length, 1,857 mm in width, and 1,507 mm in height, with a wheelbase of 2,837 mm.
