How to Operate Turns in the Driving Test (Subject 3)?

The steps for making a left turn in Subject 3 are as follows: 1. When you hear "Turn left at the intersection ahead," turn on the left turn signal in advance (you must wait for the signal to be on for 3 seconds before turning left). 2. Observe the traffic conditions behind you on the left, and after ensuring safety, change lanes to the leftmost turning lane (usually the innermost lane in the test). 3. After confirming safety, turn on the left turn signal again, then turn widely at low speed through the intersection. 4. If you encounter a red light, when you hear "Left turn encountering a red light," remember to brake to slow down and shift to a lower gear. 5. When about to stop, press the brake and clutch (many people get nervous and only press the brake, causing the engine to stall), smoothly stop the vehicle, and wait for the red light countdown to end. 6. When the red light countdown reaches about 10 seconds, get ready by turning on the turn signal, pressing the clutch to engage 1st gear, keeping the brake pressed, and when the light turns green, release the handbrake, release the brake, lift the clutch, and accelerate to move. After the speed increases, shift to 2nd gear, and if the surrounding traffic conditions are good, you can turn widely and pass quickly. 7. After completing the turn, enter the straight lane, accelerate quickly to shift to 3rd gear, and prepare for the next test item.

Does the Roewe i5 have a heated rearview mirror function?

The Roewe i5 is equipped with a heated rearview mirror function. The switch for the heated rearview mirror is located on the center console, next to the front windshield defogger switch, and is marked with an icon featuring three curved upward arrows alongside a rectangle. The heated rearview mirror is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rain or fog, eliminating the need for the driver to manually wipe the mirror frequently, thereby reducing driving hazards. How to use the heated rearview mirror function: There are generally two ways to activate the heated rearview mirror function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as there is an adjustment button on the driver's side. Principle of the heated rearview mirror function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees Celsius. Heat is then emitted from both left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface become smaller, and fog gradually dissipates, effectively heating the mirror and removing frost. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the heated rearview mirror function: The principle of the heated rearview mirror involves adding electric heating wires to the mirror, which consume a significant amount of power. When using this function, ensure the car is in an active state (engine running). Avoid activating the heated rearview mirror when the car is stationary to prevent draining the car battery, which could then fail to provide sufficient power for starting the vehicle. Other methods for defogging the rearview mirror include: Opening windows for air circulation: Crack open the side windows slightly to create airflow between the inside and outside of the car, reducing the temperature difference and allowing the fog to dissipate gradually. Adjusting the car's air conditioning to the appropriate setting can also help defog the mirror by blowing warm air.

What Does an Exclamation Mark Indicate When Driving?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. Many warning lights on the car dashboard feature an exclamation mark, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and windshield wiper fault indicator. Below is a detailed explanation of the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circled parenthesis. This represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Anomaly: An exclamation mark with a horizontal line below a parenthesis. This is the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, signaling a fault in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. Steering System Fault Indicator: A yellow circle with a steering wheel symbol and a yellow exclamation mark next to it. This indicates looseness in the power steering system connections, leading to steering fluid leakage. Other possible causes include excessive wear of the steering gear piston cylinder, poor sealing of oil seals, control valve sticking or damage, excessive air in the power steering system causing abnormal steering, or foreign objects in the steering hydraulic line causing the steering pump flow control valve to stick. Solution: If low on fluid, replenish it promptly. Replace oil pipes, power steering pump, or power steering gear. Inspect all connection points of the oil pipes and tighten the bolts. Check the steering gear, steering pump control valve, oil cup filter, steering fluid, and clean the entire power steering system. Windshield Wiper Fault Indicator: This fan-shaped indicator light signals a fault in the wiper system. Inspect the wipers for issues. In addition, during daily vehicle use, the fault lights displayed on the dashboard are categorized into yellow and red for different levels of severity: Yellow indicates a fault in the corresponding system that is not very severe. Reduce speed and proceed to a repair shop to eliminate potential safety hazards. Red indicates a very serious issue in the corresponding system. In such cases, do not continue driving. Pull over safely and seek professional assistance to prevent unpredictable risks to the vehicle and personal safety. Note: When the car is started, all lights will illuminate for an automatic system check and will turn off after the check is completed. If a light does not illuminate when the ignition is turned on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection and elimination of safety hazards.

What is the normal tire pressure for the Emgrand GS?

The normal tire pressure range for the Emgrand GS is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The Emgrand GS's tire pressure monitoring system only displays a warning symbol on the dashboard below the driver's seat when the tire pressure is abnormal. To check the tire pressure, you can find the standard value on the B-pillar or the inside of the left front door, and use a tire pressure gauge to compare the measured tire pressure with the standard value to determine if it is high or low. Generally, a tire pressure above 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Typically, it will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, the tire needs to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to come on. Simply reset the tire pressure to resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire valve. If the sensor is damaged due to impact while driving, the tire pressure warning light will come on. For sensor damage, the only solution is to replace it with a new one.

How to Tell When Tires Need Replacement

Methods to determine if tires need replacement: 1. Tread wear approaching wear indicators: All tire brands have wear indicators at the bottom of tread grooves. Passenger car tires typically have wear indicator height of 1.6mm, while truck tires have 2.4mm; 2. Visible tire damage: This includes tread cracks, bulges, missing rubber chunks, or severe sidewall wear; 3. Expired service life: Tires generally last about 5 years. Beyond this period, aging occurs primarily through surface hardening and cracking. As one of a vehicle's critical components, tires directly contact road surfaces and work with suspension systems to absorb driving impacts.

What is an Automatic Clutch?

An automatic clutch, also known as an automatic clutch control system, is an intelligent clutch control system developed for manual transmission vehicles. Without altering the original gearbox and clutch, it adds an independent system controlled by a microcomputer to manage the engagement and disengagement of the clutch, thereby achieving the effect of driving without stepping on the clutch. When the engine speed decreases during high-speed driving, if the vehicle's speed exceeds the engine speed, the clutch disc and the engine flywheel will automatically separate, allowing the car to continue high-speed driving using its own inertia. When the vehicle's speed drops to match the engine speed, the clutch disc and the engine flywheel will automatically re-engage, entering the driving state.
