Cruise control. It’s a feature in most modern cars that can significantly enhance your driving experience, especially on long journeys. But if you’re new to driving, or perhaps just haven’t used it before, navigating the controls might seem a little daunting. This guide provides a comprehensive overview of how to use cruise control effectively and safely, maximizing its benefits while minimizing potential risks.
Understanding Cruise Control: More Than Just Speed Holding
Cruise control is a system that automatically maintains a vehicle’s speed as set by the driver. It does this by taking over the accelerator, freeing your foot from constant pressure. This can lead to greater comfort, especially on long highway drives, and improved fuel efficiency in certain conditions. However, it’s crucial to understand its limitations and use it responsibly.
The Benefits of Cruise Control
One of the primary benefits is driver comfort. By eliminating the need to constantly depress the accelerator pedal, cruise control reduces fatigue, particularly on long trips. This can lead to a more alert and less stressed driver.
Another significant advantage is fuel efficiency. Maintaining a constant speed, especially on flat terrain, can optimize your vehicle’s fuel consumption. Rapid acceleration and deceleration consume more fuel, so a steady pace, facilitated by cruise control, can lead to savings.
Furthermore, cruise control can help you maintain legal speed limits. It can be easy to inadvertently creep over the speed limit, especially on monotonous highways. Cruise control ensures you stay within the set speed, reducing the risk of speeding tickets.
When Not to Use Cruise Control
While cruise control offers numerous benefits, it’s essential to recognize situations where its use is unsafe or inappropriate. These include:
- Heavy Traffic: Stop-and-go traffic requires constant adjustments in speed, rendering cruise control impractical and potentially dangerous.
- Inclement Weather: Rain, snow, ice, or fog can significantly reduce tire traction. Cruise control may lead to loss of control in these conditions.
- Winding Roads: Cruise control is best suited for straight, flat roads. On winding roads, it can lead to uncomfortable and potentially unsafe cornering.
- Unfamiliar Roads: Unexpected changes in road conditions, such as potholes or construction zones, can make cruise control a risky choice.
- Hilly Terrain: While some advanced cruise control systems can handle hills well, older systems may struggle to maintain a consistent speed, leading to inefficient gear changes and fuel consumption.
Locating and Identifying Cruise Control Controls
Before using cruise control, you need to identify where the controls are located in your vehicle. The placement varies depending on the make and model of your car.
Steering Wheel Controls
Most modern vehicles have cruise control buttons located on the steering wheel. These buttons typically include:
- On/Off or Cruise: This button activates and deactivates the cruise control system.
- Set or Set-/: This button sets the desired speed and engages the cruise control. It also lowers the set speed when cruise control is engaged.
- Resume or Res+: This button resumes the previously set speed after braking or deactivating the system. It also increases the set speed when cruise control is engaged.
- Cancel: This button temporarily deactivates the cruise control without erasing the set speed.
Stalk-Mounted Controls
In some older vehicles, the cruise control controls are located on a stalk extending from the steering column, often on the left side. The stalk typically has a rotating collar to turn the system on and off, and buttons or levers to set, resume, and cancel the speed.
Dashboard Indicator Lights
Once cruise control is engaged, an indicator light will illuminate on the dashboard. The icon varies depending on the vehicle, but it usually features a speedometer symbol. This light confirms that the system is active and maintaining the set speed.
Step-by-Step Guide to Activating and Using Cruise Control
Now that you understand the controls and their locations, let’s walk through the process of using cruise control.
Step 1: Activate the System
First, make sure you are driving on a suitable road with minimal traffic and good visibility. Accelerate to your desired speed. Once you reach the desired speed, press the “On/Off” or “Cruise” button to activate the cruise control system. This does not necessarily set the speed; it merely enables the system.
Step 2: Set Your Speed
With the system activated, press the “Set” or “Set-” button. This will set your current speed as the cruise control speed. You can then remove your foot from the accelerator pedal. The car will maintain the set speed automatically.
Step 3: Adjust Your Speed
Once cruise control is engaged, you can adjust your speed using the “Res+” and “Set-” buttons. Pressing “Res+” will increase your speed in small increments (typically 1-2 mph per press), while pressing “Set-” will decrease your speed. Some systems allow you to hold down the button for continuous adjustment.
Step 4: Deactivate Cruise Control
There are several ways to deactivate cruise control:
- Braking: Pressing the brake pedal will immediately disengage the cruise control system. This is the most common and safest way to deactivate the system in an emergency.
- Cancel Button: Pressing the “Cancel” button will temporarily deactivate the system without erasing the set speed.
- On/Off Button: Pressing the “On/Off” or “Cruise” button will completely deactivate the system, erasing the set speed.
Step 5: Resume Your Speed
After deactivating the cruise control, you can resume your previously set speed by pressing the “Resume” or “Res+” button. The car will automatically accelerate to the set speed. However, be aware of the surrounding traffic and ensure it is safe to accelerate.
Advanced Cruise Control Systems: Adaptive Cruise Control (ACC)
Modern vehicles are increasingly equipped with adaptive cruise control (ACC), an advanced version of traditional cruise control. ACC uses radar or lidar sensors to detect the distance and speed of the vehicle in front.
How Adaptive Cruise Control Works
ACC automatically adjusts your car’s speed to maintain a safe following distance from the vehicle ahead. If the vehicle in front slows down, ACC will automatically decelerate your car. If the vehicle speeds up or changes lanes, ACC will accelerate back to your set speed.
Benefits of Adaptive Cruise Control
ACC offers several advantages over traditional cruise control:
- Increased Safety: By automatically maintaining a safe following distance, ACC reduces the risk of rear-end collisions.
- Reduced Driver Workload: ACC can significantly reduce driver fatigue, especially in moderate traffic conditions.
- Smoother Driving Experience: ACC provides a more natural and comfortable driving experience by mimicking human driving behavior.
Limitations of Adaptive Cruise Control
While ACC is a valuable safety feature, it’s crucial to understand its limitations:
- Sensor Limitations: ACC sensors can be affected by inclement weather, such as heavy rain, snow, or fog.
- Cut-Ins: ACC may not react quickly enough to vehicles that suddenly cut into your lane.
- Malfunctions: ACC systems are complex and can malfunction, so it’s essential to remain vigilant and be prepared to take over control of the vehicle.
- Not a Replacement for Attentive Driving: ACC is an assistance feature, not a substitute for attentive driving. Drivers must always remain alert and be ready to intervene if necessary.

Using cruise control responsibly requires awareness and adherence to safety guidelines.
Stay Alert and Attentive
Even with cruise control engaged, it’s crucial to remain alert and attentive to your surroundings. Monitor traffic conditions, road hazards, and other potential dangers.
Be Prepared to Take Over
Always be prepared to deactivate cruise control and take over control of the vehicle. Keep your foot close to the brake pedal and be ready to react quickly to changing conditions.
Avoid Distractions
Avoid distractions such as cell phones, eating, or adjusting the radio while using cruise control. Focus your attention on driving.
Regularly Check Your Speed
Occasionally check your speed to ensure that the cruise control is maintaining the desired speed and that you are not inadvertently exceeding the speed limit.
Practice Makes Perfect
Before using cruise control in challenging conditions, practice using it on familiar roads with minimal traffic. This will help you become comfortable with the controls and understand how the system responds.
Troubleshooting Common Cruise Control Issues
While cruise control systems are generally reliable, occasional issues may arise.
Cruise Control Not Engaging
If the cruise control fails to engage, check the following:
- System Activation: Ensure that the system is turned on using the “On/Off” or “Cruise” button.
- Speed Requirements: Cruise control typically requires a minimum speed (e.g., 25 mph) to engage.
- Brake Pedal Switch: A faulty brake pedal switch can prevent the cruise control from engaging.
- Vehicle Problems: Certain vehicle problems, such as engine malfunctions or transmission issues, can disable the cruise control system.
Cruise Control Disengaging Unexpectedly
If the cruise control disengages unexpectedly, consider these potential causes:
- Brake Pedal Contact: Accidentally brushing the brake pedal can disengage the system.
- Road Conditions: Bumps or potholes can sometimes trigger the system to disengage.
- System Malfunction: A fault in the cruise control system itself may cause it to disengage.
Cruise Control Not Maintaining Speed
If the cruise control fails to maintain a consistent speed, especially on hills, it could indicate a problem with the system or the vehicle’s engine.
Seeking Professional Assistance
If you encounter persistent problems with your cruise control system, it’s best to seek professional assistance from a qualified mechanic. They can diagnose the issue and perform the necessary repairs.
Mastering cruise control can significantly enhance your driving experience, providing comfort, convenience, and potential fuel savings. By understanding the system’s features, limitations, and safety guidelines, you can use it effectively and responsibly, making your journeys safer and more enjoyable. Always prioritize safety and remain attentive to your surroundings, even when cruise control is engaged.
What is cruise control and how does it work?
Cruise control is a system in a vehicle that automatically maintains a set speed as determined by the driver. Once engaged, the system controls the throttle of the engine to keep the vehicle traveling at the desired speed, allowing the driver to remove their foot from the accelerator pedal. This can reduce driver fatigue, especially on long highway drives.
The system typically uses sensors to monitor the vehicle’s speed. This data is fed to a control module which adjusts the throttle as needed to maintain the preset speed. If the vehicle encounters an incline, the system increases engine power to avoid slowing down. Conversely, when descending a hill, it may reduce power or even apply light braking to prevent the vehicle from exceeding the set speed.
When is it appropriate to use cruise control?
Cruise control is most effectively and safely used on long stretches of relatively flat, open highway with consistent traffic flow. Ideal conditions include minimal traffic congestion and limited need for frequent speed adjustments or lane changes. Maintaining a constant speed in these situations can improve fuel efficiency and reduce driver fatigue.
However, it’s crucial to avoid using cruise control in heavy traffic, inclement weather conditions (rain, snow, ice, fog), or on winding or hilly roads. These situations demand more active driver involvement and quick reactions, which can be hampered by relying on the automated system. Always prioritize situational awareness and the ability to react immediately to changing road conditions.
What are the benefits of using cruise control?
One major benefit of cruise control is its ability to reduce driver fatigue on long journeys. Maintaining a constant speed without constantly applying pressure to the accelerator pedal can significantly lessen strain on the driver’s leg and foot, leading to a more comfortable and less tiring driving experience. This is particularly beneficial for those who frequently travel long distances.
Furthermore, using cruise control can often lead to improved fuel efficiency. By maintaining a consistent speed, the vehicle’s engine operates more efficiently, minimizing unnecessary acceleration and deceleration. This steady state of operation reduces fuel consumption compared to fluctuating speeds controlled manually, resulting in potential cost savings over time.
What are the dangers of using cruise control?
One of the primary dangers associated with cruise control is a potential decrease in driver attentiveness. The automated nature of the system can lead to a sense of complacency, causing drivers to become less vigilant and responsive to changes in their surroundings. This diminished awareness can significantly increase the risk of accidents, particularly in unpredictable traffic situations.
Another significant risk is the delayed reaction time in emergency situations. When relying on cruise control, drivers may be slower to react to sudden braking or lane changes required by other vehicles. This delay stems from the time it takes to disengage the system and regain full manual control, which can be crucial in avoiding collisions. Always be prepared to override the system and take immediate action when necessary.
How do I properly engage and disengage cruise control?
To engage cruise control, first accelerate to the desired speed. Then, press the “set” or “cruise” button on your steering wheel. The vehicle will then maintain that speed. Ensure you are on a suitable road with appropriate conditions before engaging the system. Always familiarize yourself with your vehicle’s specific cruise control controls, as they can vary between manufacturers.
To disengage cruise control, you have several options. The most common method is to tap the brake pedal lightly, which will automatically deactivate the system. Alternatively, you can press the “cancel” or “off” button on the steering wheel. In some vehicles, pressing the accelerator pedal beyond a certain point may also disengage the cruise control, although this is less common.
What is adaptive cruise control and how does it differ from standard cruise control?
Adaptive cruise control (ACC) is an advanced version of standard cruise control that uses radar or lidar sensors to maintain a set speed and a safe following distance from the vehicle ahead. Unlike standard cruise control, which only maintains a fixed speed, ACC automatically adjusts the vehicle’s speed to match the flow of traffic. This helps to prevent rear-end collisions by automatically slowing down or even braking if the vehicle in front slows down.
The key difference lies in ACC’s ability to adapt to changing traffic conditions. Standard cruise control requires the driver to manually adjust the speed or disengage the system when encountering slower traffic. ACC, on the other hand, handles these adjustments automatically, making it a more convenient and safer option in moderate to heavy traffic. However, drivers must remain vigilant and be prepared to override the system if necessary.
What safety precautions should I take when using cruise control?
Always maintain a high level of alertness and situational awareness, even when using cruise control. Regularly scan your surroundings, monitor traffic patterns, and be prepared to take manual control of the vehicle if necessary. Never become complacent or rely solely on the system, as it is not a substitute for attentive driving.
Avoid using cruise control in adverse weather conditions such as rain, snow, ice, or fog. These conditions require more precise vehicle control and quicker reactions, which can be compromised when relying on automated systems. Similarly, avoid using cruise control on winding or hilly roads where frequent speed adjustments are necessary. Prioritize safety and exercise caution at all times.
