Maserati GranTurismo 2024 Speed Limiter User Manual
Introduction
The Speed Limiter function has a number of advantages. It primarily encourages safer driving by assisting drivers in avoiding unintentionally going over the posted speed limit. Drivers can ensure they follow the posted speed limits and lower their risk of accidents by setting a maximum speed. The Speed Limiter can also improve fuel economy by promoting smoother, more controlled driving. Drivers can reduce their fuel consumption and make driving more environmentally friendly by avoiding abrupt acceleration and keeping their speed constant.
The speed limiter on the Maserati GranTurismo 2024 is a useful safety feature that encourages cautious and safer driving. It aids motorists in obeying speed limits, controlling speed under particular circumstances, and maximizing fuel economy. The GranTurismo’s Speed Limiter gives the driving experience an additional layer of control and assurance by fusing performance and safety.
Speed Limiter – SL
Using the controls located on the right side of the steering wheel, the driver can set a maximum speed limit (SL function) or maintain a constant cruise control
(CC function) speed without operating the accelerator pedal. If set, these
two functions SL and CC will exclude each other according to the driver’s manoeuvres.
SL allows the driver to set the maximum speed limit to be reached by the vehicle. It is possible to exceed the set maximum speed by firmly pressing on the accelerator pedal. After that, if the SL function is still active, once the driving speed returns under the set value, the SL function will continue to limit the speed.
Controls
The controls are located on the right side of the steering wheel.
Control configuration depends on which driver assist systems are installed to the vehicle (see “Controls on Steering Wheel” in section Dashboard and Instruments and Controls).
There is a specific button to engage and disengage the SL.
Control “pulse activation” buttons have the following functions:
ON/OFF “pulse activation” button to engage/disengage SL system.
Multifunction switch:
SET + / SET − : Increase /Decrease speed, set current speed
RES: Resume previously set speed when system is in paused status- CANC: Pause (SL disen-gaged). The set limit is not deleted (see paragraph
“Temporary Deactivation” in this chapter) - Displayed Information
Apart from the pop-up messages at the centre of the display, SL system status is represented by icons at the top right of the display, in the dedicated area. See Instrument cluster overview in section “Dashboard Instruments and Controls”. Displayed information depends on system status: ready, set, temporarily cancelled or override. - Activation
Push the ON/OFF button to engage the system. The white light in upper right sector of the display will illuminate and the last set speed is shown. 
- To disengage the system, push the same button a second time. The light will turn off and a new message pops up for 5 seconds, then the display returns to the previous setting.
When the SL function is activated, the system automatically disengage the CC function if it was active. See chapter
“Cruise Control – CC” in this section for further information.
NOTE:
- The system must be disengaged when not in use.

The ISA system, where provided, is combined with the Speed Limiter system and TSA (Traffic Sign Assist) system and suggests an automatic speed adjustment to the driver based on the speed limit for the road being travelled. You can decide whether to accept or reject the proposal to adjust the speed set by the SL to match the one suggested by the speed limit symbol, according to manual or automatic function set, by using the RES button located on the steering wheel. 
- A corresponding message will be shown on the instrument cluster display.
- Activation / Deactivation
Activation
The system can be activated/deactivated by the Setting list on the MIA screen (see “Functions of Settings Menu on MIA” in section
“Dashboard Instruments and Controls”).
Deactivation
The system is deactivated under the following conditions:
- When the Traffic Sign Recognition system is deactivated;
When the Speed Limiter device is deactivated.
NOTE:
Selecting “Traffic Sign Assist Sensitivity” it is possible to set the speed increment to which the ISA system will adjust, up to a maximum of 10 km/h above the speed limit sign detected by the system, or the speed decrement to which the ISA system will Driving and Driver Assistance Systems adjust, down to a minimum of 10 km/h
below the speed limit sign detected by the system. In these cases, the road sign information shown on the instrument panel display will remain that detected by the TSA system.
Indications on the Display
The system status is always shown by a dedicated green icon on the instrument cluster display, in the upper right of the screen.
Acceptance / Rejection of the Suggested Speed
The system can be activated if the driver has previously activated:
The Speed Limiter device;
The Traffic Sign Assist system.
When these systems are active, the instrument cluster display can show an icon that indicates the suggested speed (provided by the TSA system) which the driver can decide to accept or reject using the RES button on the steering wheel.
- To accept the proposed speed and consequently adjust the speed set by the Speed Limiter, push the RES button. If ISA is set in “Manual” mode on the MIA screen, RES button confirm the suggested speed. If ISA is set in
“automatic” mode on the MIA screen, the driver can push RES button within 5 seconds to reject the suggested speed; otherwise the system will adapt automatically the speed.
If the driver accepts the value suggested by the ISA or if the speed set using the Speed Limiter device is the same as the that detected by the Traffic Sign Assist system, the speed limit sign on the instrument cluster display will be highlighted with a green circle.
