Activating cruise control and setting your speed

Cruise control lets you hold a steady speed without keeping your foot on the gas pedal. To turn it on, look for the cruise control button or stalk on your steering wheel—it may be labeled "CRUISE" or show a speedometer symbol. Press the button to set up the system; you'll usually see a light on your dashboard confirming it's ready.

Once cruise control is active, accelerate to the speed you want to maintain using the gas pedal as normal. When you reach that speed, press the "SET" or "COAST" button (location varies by car model). The system will now hold that exact speed without you touching the pedal. You can adjust the set speed up or down using the plus and minus buttons on the stalk or steering wheel controls.

Different cars have different button layouts. Some use a stalk you pull or push; others have buttons on the wheel itself. Check your owner's manual or look at the steering wheel controls to find your specific setup. The dashboard display will show your set speed once it's locked in.

Key Takeaways

  • set up cruise control with the main button on your steering wheel, then accelerate to your desired speed and press SET to lock it in.
  • Use the plus and minus buttons to adjust your set speed up or down without touching the gas pedal.
  • Cruise control only works safely on highways and open roads where traffic moves at a constant speed.
  • Pressing the brake pedal, clutch pedal, or the CANCEL button will when ready turn off cruise control.
  • Never use cruise control on wet roads, in heavy traffic, on hills, or when you feel drowsy.

When cruise control is safe to use

Cruise control works best on long, straight highways with steady traffic flow and clear visibility. Use it during daytime driving or well-lit nighttime conditions when you can see the road clearly ahead. The system is designed for situations where you can maintain the same speed for several minutes without needing to brake or accelerate.

Avoid cruise control in rain, snow, or fog. Wet roads reduce tire grip, and your car may not slow down quickly enough if you need to brake suddenly. Heavy traffic, stop-and-go driving, and congested city streets are also poor conditions for cruise control—you'll be turning it off and on constantly, which defeats the purpose.

Do not use cruise control on steep hills or mountain roads. Your engine may struggle to maintain speed going uphill, and the system can cause your car to accelerate dangerously on downhill sections. Hills require active pedal control to stay safe.

Disengaging cruise control

You can turn off cruise control three ways. The easiest is to press the brake pedal—braking when ready cancels cruise control on every car. You can also press the CANCEL button on your steering wheel controls, which disengages the system but keeps your current speed in memory. Pressing the main cruise control button again will turn the entire system off.

If you press CANCEL, your set speed stays stored. When you accelerate back to that speed and press SET again, the system will resume holding that speed. This is useful if you briefly need to slow down for traffic, then want to return to your previous cruising speed. Pressing the brake pedal, however, clears the stored speed on most vehicles.

Adaptive cruise control and distance settings

Many newer cars have adaptive cruise control, which automatically slows your car if traffic ahead slows down. Instead of a straightforward SET button, you'll see controls for following distance—usually shown as bars or numbers on your dashboard. Use the plus and minus buttons to choose how many car lengths you want between you and the vehicle ahead.

Adaptive systems maintain your set speed when the road is clear, then reduce speed to match traffic automatically. When traffic clears, the car speeds back up to your set speed. This is safer in moderate traffic than standard cruise control, but you still need to stay alert and ready to brake. Never rely on adaptive cruise control to stop your car completely—it's designed to reduce speed, not replace your attention.

Check your owner's manual to learn your car's specific distance settings. Some cars show distance in seconds (typically 1 to 3 seconds of following time), while others use numbered levels. Shorter distances mean you'll follow closer; longer distances give you more reaction time.

Common mistakes and safety reminders

The biggest mistake is using cruise control when you're tired or drowsy. Cruise control removes the physical feedback of the gas pedal, which can make it easier to zone out. If you feel your attention drifting, turn off cruise control and pull over to rest. Drowsy driving is dangerous regardless of what features your car has.

Do not set cruise control and then remove your hands from the wheel or look away from the road. You still need to steer, watch for hazards, and be ready to brake at any moment. Cruise control only controls your speed—it does not drive the car for you. Stay engaged and alert at all times.

Another common error is forgetting that cruise control is still on. If you slow down for traffic and then the road clears, your car will suddenly accelerate back to your set speed. Always be aware of whether cruise control is active, and check your dashboard to confirm your set speed before using it.

Troubleshooting cruise control problems

If cruise control won't turn on, check that your car is moving at least 25 miles per hour—most systems require a minimum speed to set up. Also verify that the main cruise button is actually on; some cars require you to press it first, then press SET. If the light on your dashboard doesn't appear, the system may not be engaged.

If cruise control turns off unexpectedly, you may have accidentally bumped the CANCEL button or brake pedal. Some cars also disable cruise control if they detect a problem with the braking system or engine. Check your owner's manual for warning lights related to cruise control, or have a mechanic inspect the system if it keeps shutting off.

If your adaptive cruise control isn't slowing down for traffic ahead, the sensors may be dirty or blocked. Clean the front of your car where the radar or camera sensors are located. If the problem continues, the sensors may need professional calibration or repair.

Frequently Asked Questions

Can I use cruise control in the rain?

No. Wet roads reduce tire grip, and your car may not brake quickly enough if you need to stop suddenly. Cruise control removes your active control of speed, which is unsafe when traction is reduced. Wait until the road is dry before using cruise control.

What happens if I press the gas pedal while cruise control is on?

Your car will accelerate, and cruise control will disengage. Once you release the gas pedal and return to your set speed, you can press SET again to re-engage cruise control at that speed. On some cars, the system stays in memory and will resume automatically.

Is adaptive cruise control the same as self-driving?

No. Adaptive cruise control only controls your speed and following distance. You must steer the car, watch the road, and be ready to brake at any time. It is not a self-driving system and does not replace your attention or control of the vehicle.

Can I use cruise control on city streets?

Not safely. City driving involves frequent stops, turns, and speed changes. You'll be turning cruise control off and on constantly, which makes it pointless and distracting. Cruise control is designed for highways and open roads with steady traffic flow.

Why did my cruise control stop working after I hit the brakes?

That's normal. Pressing the brake pedal disengages cruise control on every car. Your set speed may still be stored in memory, so you can accelerate back to that speed and press SET to resume. If cruise control won't turn back on at all, check that you're going at least 25 miles per hour and that the main cruise button is activated.
