The acceleration programs can be changed using the two arrow buttons on the top of the device. By selecting the desired acceleration program in each mode, the driver can fine-tune each mode per their driving style (e.g. select SPORT 9 & RACE 5). Sprint Booster modes and programs are transmission type specific for better function and performance. The driver can select the transmission type through a slide switch located on the right side of the device. The device will then automatically adjust the programs according the type of transmission selected. There are 36 programs in total (18 for manual transmissions and 18 for automatic transmissions). Valet mode limits the acceleration of the vehicle by 55%, 65%, or 75% (comes in three selectable levels). It is activated and deactivated with a three-digit PIN. By limiting the acceleration, there will be a significant reduction in the vehicle's performance. The Pedal Lock mode provides extra protection against unauthorized vehicle use. The driver can deactivate the acceleration ability of the vehicle through a 3 digit PIN. The menu for Valet and Pedal Lock mode is accessed when the vehicle is stationary and the Sprint Booster is off, by pressing the two arrow buttons simultaneously. In addition to increased throttle response for effortless downshifts and safer overtaking, there is also a noticeable improvement to the transmission’s shifts (on vehicle’s equipped with automatic transmissions).
