Number four on the wheel represents “direction.”
this is also called a paddle shifter, or an h-pattern. it repeats in forward and reverse directions. for example, when you are in drive mode, pressing #4 will cause the cars' speed to decrease, while pressing number 5 will increase it's speed. pressing down on the lever before engaging gear will allow one to disengage the clutch. the left side of this controller moves gears up and down; pressing right moves gears left and right.
each of these motions has an associated verbal command that gets mumbled by inexperienced drivers at high speeds: rack off! some people love them because they're faster than rotary controls (who often didn't go
what does 4d mean in a vehicle?
this is not a common term.
google search result for ‘4d': enhanced driver awareness to bring you more safety, convenience, and enjoyment—with less worry
backseat infotainment systems that offer up entertainment similar to what’s found in the front seat, with wireless headphones that allow passengers to control their own listening experience; responsive suspension systems with varying degrees of stiffness based on the car's speed; cameras mounted near each corner of the vehicle for optimal visibility around blind spots.
4d or 4 dimensions are put into play when any time there is a change in speed or direction by 10 mph. there should be no other major changes — other than transmission type (syncromesh over double declutch)
is 4d the same as 4wd?

what does 4d mean on a gear shift?
generally, the meaning of “4d” on a gear shift is that the driver can manually engage or disengage all of the gears.
the 4th gear in particular refers to a driving mode where engine torque and grip is most effectively used for holding a car on an even-speed downhill slope with exceeding low fuel consumption. gear shifting so as to keep speeds constant without too much braking or accelerating would be most efficient with this driving mode activated.

is 4d all wheel drive?
technically, it isn't.
4d all wheel drive is an ad-hoc term created to describe vehicles with four-wheel drive and a differential system that splits torque automatically to the front and rear axles without external intervention. these vehicles are not strictly speaking 4×4s because they still use limited slip differentials which limit how much torque can be distributed between the front and rear axles under harsh conditions. the manufacturers refer to these vehicles as 4wd or awd rather than 4d to avoid confusion with other types of four wheelers like quads, buggies, big rigs, etcetera.
a vehicle can technically be classified as a true ‘4d' if its traction control system moderates
