Why is there a plus and minus on my steering wheel?

In most modern cars, the plus (+) and minus (−) marks on or near the steering wheel indicate two common kinds of controls: paddle shifters for manual gear changes in an automatic transmission, and media or vehicle setting controls such as volume. The exact function depends on the model, so check your owner's manual if you’re unsure.

As cars have grown more feature-rich, these symbols can also appear on cruise-control interfaces or digital menus. This article explains the typical meanings and how to verify which applies to your vehicle, so you can use the controls safely and confidently.

Common meanings of the plus and minus on the steering wheel

What you see on the wheel generally falls into two main families. The precise layout varies by brand and trim.

Paddle shifters for manual gear changes

In many cars with automatic transmissions, you can manually shift gears using two paddles behind the steering wheel. The right paddle labeled “+” upshifts, while the left paddle labeled “−” downshifts. This mode is typically available when the transmission is set to manual, sport, or an equivalent mode and is indicated on the instrument cluster.

• Usually located behind the steering wheel within easy reach of your fingers.


• Active only when the car is in a manual or sport shift mode; the current gear is shown on the dashboard.

Note that not all automatics offer paddle shifters, and some models use these paddles differently or as part of a broader driving-mode system.

Media and other wheel controls

On many vehicles, the plus and minus controls adjust audio volume, while others use the same symbols to skip tracks or change radio presets when pressed in combination with other buttons. In some models, the symbols also control navigation or display brightness within the instrument cluster.

• Volume up (plus) and volume down (minus) control the cabin’s audio level.


• In some setups, these buttons may skip to the next/previous track or station when used with a modifier button.


• In other configurations, they navigate menus or adjust screen brightness inside the driver information display.

Because the exact function can vary widely, check the button icons and your owner's manual for your specific model and trim.

How to identify and use the controls in your car

To determine the exact function of the plus and minus on your steering wheel, follow these steps in a safe environment and with the car stationary if possible.

• Look for nearby icons or labels on the buttons (e.g., VOL, a speaker icon, or a car/gear emblem) which hint at their purpose.


• Check for behind-the-wheel paddles: two small levers behind the steering wheel are a common paddle-shift setup, usually with the right paddle marked “+” and the left marked “−”.


• Consult the owner’s manual or the manufacturer’s website for your exact model and trim; you’ll find a map of the controls there.


• If you’re unsure, contact a dealer or a qualified technician to avoid distractions or unintended actions while driving.

Accurately identifying the function helps you use the wheel controls safely and effectively in everyday driving.

What to do if something isn’t working or feels wrong

If the controls don’t respond as expected—such as the volume not changing when you press the plus or minus, or the paddles not shifting gears—the issue could be a setting, a software fault, or a blown fuse. Start with a quick infotainment-system reset, check for any available software updates, and consult the manual or a dealer if problems persist. Persistent faults should be inspected to ensure safe operation while driving.

Summary

The plus and minus marks on steering wheels serve multiple roles across different vehicles. They most commonly indicate paddle shifters for manual gear changes in automatics, and they can also control audio volume, track changes, or other display and cruise-control functions. By checking your model’s icons, testing in a safe setting, and consulting the owner’s manual, you can identify the exact purpose and use these controls safely on the road.

What are the plus and minus flaps on the steering wheel?

The plus (+) and minus (-) paddles on a steering wheel, also known as paddle shifters, allow a driver to manually change gears in an automatic transmission vehicle. The plus paddle, usually on the right, is for upshifting to a higher gear, while the minus paddle, usually on the left, is for downshifting to a lower gear.

How to use them

• Enter manual mode: First, put the car in manual mode, which is often done by moving the gear shift lever to the side of "D" for drive. 
• Upshift: Pull the right paddle marked with a "+" to shift to a higher gear. 
• Downshift: Pull the left paddle marked with a "-" to shift to a lower gear. 
• Automatic protection: The system will not allow you to shift into a gear that is too high or too low, which prevents potential damage to the engine. The indicator light may blink to let you know if a shift is not permitted.

Why you might use them

• More control: They provide greater control over the vehicle, especially in situations where an automatic transmission might not react as quickly as needed, such as going downhill or in slippery conditions. 
• Engine braking: Use the minus (-) paddle to downshift and slow the car down using the engine's power, which can be helpful on long descents and can help preserve brake pads. 
• Performance driving: They offer a more engaging and sporty driving experience, similar to a manual transmission, and can be used for quick acceleration by downshifting to a lower gear. 

What is the -+ on my shift gear for?

M is for Manual.
This position allows you to shift gears, manually giving you more control over the car's power. +/- Sign: This means the transmission can shift up or down.

What do the plus and minus mean on a steering wheel?

The plus (+) and minus (-) signs on a steering wheel are typically for paddle shifters, which allow you to manually change gears in an automatic transmission for more control. The minus (-) side, usually on the left, is for downshifting to a lower gear, while the plus (+) side, typically on the right, is for upshifting to a higher gear.

How to use paddle shifters

• Downshifting: Pull the left paddle (marked with "-") to downshift. This is useful for increasing engine braking on steep downhills, providing more torque when accelerating, or having more control in slippery conditions. 
• Upshifting: Pull the right paddle (marked with "+") to upshift. This can help with fuel economy on the highway or give you more power when needed. 
• Manual mode: When you use a paddle shifter, the car often enters a temporary manual mode, which may be indicated on the instrument panel with an "M". 
• Limitations: The car's computer will still prevent you from selecting a gear that is too high or too low for the current engine speed, which could damage the engine. 

Is it bad to use paddle shifters all the time?

No, it is not bad to use paddle shifters constantly, as the car's computer will not allow you to make a damaging shift. However, using them for daily, non-performance driving can cause more wear and tear than normal automatic operation, potentially leading to increased transmission and engine temperatures, so it's generally better to save them for spirited driving. 
How paddle shifters work

• Safety: The transmission's computer will prevent you from shifting into a gear that is too low for your speed or too high for the engine, which could cause damage.
• Computer control: The computer will also shift for you if you don't, for example, upshifting automatically to prevent the engine from hitting its redline. 

Potential downsides of constant use

• Increased wear: Frequent shifting, even with paddle shifters, can lead to extra wear on the transmission compared to simply letting the automatic transmission do its job. 
• Higher temperatures: Aggressive or frequent use can increase transmission fluid and engine temperatures. 
• Not a substitute for proper maintenance: While paddle shifters are safe, they don't negate the need for regular maintenance, which is crucial for the long-term health of the transmission. 

When to use paddle shifters

• Spirited driving: Use them when you want to maximize performance or control, like during a sporty drive on a winding road. 
• Engine braking: They are useful for controlling your speed on steep descents, as this can prevent brake fade from overheating. 
• Anticipating shifts: You can use them to downshift early to be ready for a light turning green, which can be more responsive than the automatic system.
