What does the main button do on a Honda CRV?

In most modern Honda CR-Vs, the main button is the engine start/stop (Power) button. When a valid key fob is inside the vehicle, pressing the button starts or stops the engine without turning a key, as part of Honda’s keyless ignition system.

How the push-button ignition works in daily use

The button, often labeled Start/Stop or Power, works with a proximity fob. With the fob inside the car, you start the engine by pressing the brake pedal and then pressing the Start/Stop button. To turn the engine off, you typically come to a complete stop, put the transmission in Park, and press the button again.

Key levers: proximity fob and safety features

These systems rely on the proximity of the fob rather than a physical key. If the car doesn’t detect the fob, the engine won’t start. Many CR-Vs require the transmission to be in Park before shutting the engine off, and the vehicle’s electronic systems cooperate to prevent accidental shutdown while driving.

To help readers navigate practical usage, below are the typical steps used by many CR-V owners.

Starting the engine using the main button

1. With the key fob inside the vehicle and your foot on the brake, press the Start/Stop button once to start the engine.


2. Allow the instruments to initialize, then shift into Drive or Reverse and proceed as needed.

Concluding guidance for starting the engine

These steps cover most modern CR-V models that feature a push-button ignition. If the engine doesn’t start, check the fob battery, make sure the car acknowledges the fob, and ensure the brake pedal is firmly pressed.

Stopping the engine and securing the vehicle

1. Come to a complete stop and shift the transmission to Park.


2. Press the Start/Stop button again to turn the engine off. The car may default to accessories or remain in a parked state until you remove the fob.

Concluding guidance for stopping the engine

Turning off the engine is typically done when parked and the vehicle is secure. If you’re leaving the car, remove the fob and engage the parking brake as an additional precaution.

Common issues and quick troubleshooting

What to check if the main button doesn’t respond as expected:

• The key fob battery is dead or outside the detection range.


• The brake pedal isn’t fully depressed when starting.


• The 12V battery or electrical system is weak, preventing theStart/Stop system from activating.


• Vehicle safety features (such as requiring Park) aren’t met, blocking shutdown or startup.

Concluding guidance for issues and next steps

If the button still won’t respond, consult the owner's manual for model-specific instructions or contact a Honda dealer for a diagnostic check of the smart key system and the car’s electrical network.

Variations by model year, trim, and powertrain

Most Honda CR-Vs produced in recent years use a push-button Start/Stop system across trims, including hybrids. However, some very early or base models in certain markets may still rely on a traditional ignition switch with a physical key. Hybrid CR-Vs also use a Start/Stop button, though engine behavior during startup and shutdown can differ slightly due to hybrid power management.

Older CR-Vs and traditional ignition

Earlier generations or specific regional variants may feature a conventional ignition cylinder instead of a push-button. In those cases, starting the engine requires inserting a physical key and turning it, rather than pressing a button.

Hybrid CR-Vs

Hybrid versions use the same Start/Stop button concept, but the system coordinates gasoline and electric motors. You may notice different startup sounds or brief idle behavior as the vehicle transitions between power sources, especially when the battery state of charge is low.

Summary

The main Start/Stop button in a Honda CR-V is part of a keyless ignition system designed for quick, keyless access to the engine. With the fob inside the car, you start the engine by pressing the brake and then the button, and you stop it by parking and pressing the button again. If the button doesn’t respond, check the fob, power supply, and safety conditions, and consult the manual for model-specific instructions. Across recent models and trims, this button replaces the traditional key, streamlining ignition while maintaining safety and security.

Where is the main button on a Honda CRV?

Press the MAIN button on the right side of your steering wheel.

What is the power button in a Honda CRV?

The POWER button may be used to turn the power system off due to an emergency situation even while driving. If you must turn the power system off, do either of the following operations: Press and hold the POWER button for about two seconds.

What is the cruise main button on a Honda?

The "CRUISE MAIN" button on a Honda is the master switch for the cruise control system that activates the system and makes it ready to set a speed. When you press it, a "CRUISE MAIN" message appears on the dashboard, but the car will not automatically maintain a speed until you press the "SET/-" button after reaching your desired speed. This two-step process is a safety feature to prevent accidental activation.

How to use it

• To activate the system: Press the "CRUISE" or "MAIN" button on the steering wheel. A "CRUISE MAIN" message will appear on your dashboard, indicating the system is on but not yet active. 
• To set a speed: Accelerate to your desired speed, then press the "SET/-" button. The system will then maintain that speed. 
• To cancel: You can deactivate the system by pressing the "CANCEL" button, pressing the "MAIN" button again, or by pressing the brake pedal.

What does the econ button on a Honda CRV do?

The "Econ" button on a Honda CR-V optimizes the vehicle's systems to improve fuel efficiency by adjusting the throttle response, transmission shift points, and air conditioning. When pressed, it makes the engine more sluggish to save gas, shifts the transmission at lower RPMs, and reduces the power and frequency of the A/C. It is most effective for improving gas mileage during city driving or steady highway cruising.
 
How ECON mode works

• Throttle response: It makes the acceleration less sensitive, so less gas is needed for a given amount of pedal input. 
• Transmission: It changes the shift points, causing the transmission to shift up sooner and hold a higher gear to keep engine RPMs lower. 
• Air conditioning: The system is adjusted to reduce cooling power and cycles the compressor less frequently to reduce the energy load on the engine. 
• Cruise control: When on a hill, the system will be more reluctant to downshift to maintain speed, which can result in the vehicle slowing down slightly. 

When to use ECON mode

• Best for: City driving, steady highway speeds, and stop-and-go traffic. 
• Avoid for: Performance-oriented driving or situations where you need maximum power, such as climbing a steep hill or merging quickly. It is also less effective on very hot days, as the reduced A/C performance may make the cabin uncomfortable.
