Most drivers never think twice about how their car changes gears, largely because nearly all modern vehicles sold in the U.S. use automatic transmissions. According to SlashGear, less than 1% of new cars sold in the country have manual transmissions, also known as stick shifts.
Still, many automatic vehicles include a feature that lets drivers take more control when needed. If you’ve noticed a “+/-” symbol near your gear shift, here’s what it means and when Texas drivers might actually use it.
What does the +/- mean on a car gear shift?
The “+/-” symbols on an automatic car’s gear selector allow drivers to manually control gear changes without driving a traditional manual transmission. Kelley Blue Book says this feature is commonly called manual mode, sport mode or Tiptronic, depending on the manufacturer.
Moving the shifter toward the “+” shifts the car into a higher gear. Moving it toward the “-” shifts it into a lower gear.
When should you use the +/- feature?
Most drivers can leave their vehicle in standard drive mode all the time. But manually changing gears can help in certain situations common for Texas drivers.
Driving uphill
Shifting into a lower gear with the “-” can give the engine more power and torque when climbing steep roads in the Texas Hill Country without straining the vehicle.
Towing or hauling
Many Texans tow boats, campers or work trailers. Using the “+” to shift into higher gears can help reduce strain on the engine while hauling heavy loads.
Passing another vehicle
Dropping into a lower gear can provide a quick burst of acceleration when passing slower traffic on Texas highways. Drivers can shift back up afterward for better fuel efficiency.
Driving in snow or ice
During icy weather or freezing conditions on bridges and overpasses, manually controlling gear changes can help drivers maintain traction and reduce slipping.
Do you have to use the +/- controls?
No.
In most automatic vehicles, the transmission handles gear changes automatically. The “+/-” controls are optional and designed for drivers who want more control in specific driving conditions.
What are the benefits of driving a manual transmission?
Most auto experts say driving a manual vehicle comes with distinct advantages once you've mastered how to drive one.
