The method to use the cruise control on the C5 is as follows: 1. Press the ON/OFF key to activate the cruise control system, at which point the cruise control indicator on the dashboard will light up. 2. Accelerate to the desired speed, then press the SET key and release the accelerator pedal with your right foot to lock the speed at the current rate. 3. For minor speed adjustments, use the "RES" and "SET-" buttons. The main functions of the cruise control include: "SET" (set speed), "— or COAST" (decrease set speed), "RES" (resume set speed), "+ or ACCEL" (increase speed), "CANCEL" (cancel set speed), and "ON/OFF or CRUISE" (cruise control master switch). 4. To deactivate cruise control, press the brake or the cancel button. Press the RES key to return to the previously set cruise control speed.

To activate the cruise control in the C5, you need to be driving as usual and first ensure your speed is above 40 km/h—that's the basic requirement, or the system won't respond. I usually test it on the highway: press the cruise control switch button on the steering wheel (typically marked with a small speedometer icon) to turn it on. Then, accelerate to your desired speed, say 80 km/h, and press the Set or Res button to lock the current speed—the car will then maintain it automatically! To adjust speed later, use the + or - buttons on the steering wheel. To cancel cruise control, just lightly tap the brake or press the Cancel button—super easy. I often use this on long drives—it saves fuel and effort, sparing my foot from constant acceleration and helping me stay focused. But remember, don’t use it in congested city traffic; the system isn’t foolproof, and you’ll need quick reflexes in emergencies. Cruise control is smartly designed to ease driver stress, perfect for a lazy daily commute. Just familiarize yourself with the vehicle manual beforehand, as details may vary by model. Try it a couple of times, and you’ll get the hang of it.

What to Do About Engine Oil Burning?

Automobile oil burning can be resolved by repairing the engine, cleaning carbon deposits inside the engine, replacing damaged parts, and changing valve stem seals. If the situation is severe, a major engine overhaul may be necessary. It is important to address oil burning promptly when it occurs. Below are the reasons for automobile oil burning: 1. Poor valve sealing: Valves prevent oil from leaking into the combustion chamber, but over time, wear and aging can lead to poor sealing, allowing oil to enter the combustion chamber more easily. 2. Increased piston clearance: Over long-term operation, carbon deposits form on the pistons, and some wear occurs. As time passes, the piston clearance increases, making it easier for oil to enter the combustion chamber. 3. Low oil viscosity: Using oil with too low viscosity can also cause oil burning. When oil viscosity is too low, it flows more easily and can enter the cylinder, participating in combustion. 4. Excessive oil volume: High oil pressure can force some oil into the cylinder, leading to oil burning.

What Causes Engine Shaking After Cleaning the Throttle Body?

The reason for engine shaking after cleaning the throttle body is the lack of data matching. Below are the specific causes and solutions for engine shaking: 1. Carbon deposits in the car causing difficulty in ignition. At idle, it may also be accompanied by slight shaking; cleaning the throttle body and fuel injectors can resolve this. 2. Weak ignition energy from the spark plugs. If spark plugs are not replaced after the maintenance cycle, their ignition energy decreases severely, leading to misfires. 3. Insufficient fuel pressure in the low-pressure fuel circuit. Low fuel pressure directly causes the engine to misfire; specifically check the fuel pressure regulator, fuel pump, fuel filter, and internal fuel lines. 4. Weak battery. Jump-starting the car or using another battery can solve this issue. 5. Incorrect engine timing. Mismatched engine timing or skipping teeth when replacing the alternator belt in certain engine models can cause difficulty in ignition.

How old can a car's manufacturing date be to still be considered new?

Generally, a new car's manufacturing date should not exceed two months. The manufacturing date can be checked by the 10th character of the vehicle's VIN (Vehicle Identification Number). Below are the specific details about the VIN: 1. Among the 17 characters of the VIN, the first 3 characters represent the country of manufacture, the manufacturer, and the vehicle type, respectively. 2. Characters 4 to 8 of the VIN indicate vehicle characteristics, such as the vehicle category, body type, engine type, and gross vehicle weight rating. 3. The 9th character is a check digit used to verify the accuracy of the VIN. 4. The 10th character indicates the model year, which proves the year the vehicle was manufactured. 5. The 11th character represents the assembly plant, with '0' indicating original factory assembly. 6. Characters 12 to 17 of the VIN are the production sequence number, used by manufacturers to recall vehicles with quality issues based on this sequence.

What is the difference between V and H tires?

Tire V and H main differences: 1. Different speed ratings: H indicates a maximum safe speed of 210 km/h; V indicates a maximum safe speed of 240 km/h. 2. Different performance: The higher speed-rated tire V represents stronger tire performance. It's important to know that when tires roll at high speeds, they generate heat due to squeezing and deformation, so the higher-grade tire V naturally has superior resistance. Additional information: The tire shoulders and tread patterns are reinforced to reduce the likelihood of deformation, and the tire's wet grip performance is also improved.

Is it serious if a sedan's chassis is hit?

The severity of a sedan's chassis impact depends on the extent of the collision. Here are specific methods to protect the sedan's chassis: 1. Apply chassis armor coating. The protective area of the engine guard plate is too small, so applying a layer of chassis armor to the vehicle's chassis is recommended. 2. Install an engine guard plate. The engine guard plate can protect the engine from being hit by road debris and scraped by foreign objects, but this feature is not available on all models. While the guard plate can reduce damage to the engine from scraping the bottom, it may affect engine heat dissipation and could hinder the engine's downward movement during a collision, creating safety hazards. Therefore, when selecting a guard plate, it is important to choose a qualified product. 3. Be aware of the vehicle's ground clearance. Try to avoid scraping the bottom as much as possible.
