Maserati Grecale 2023 Speed Limiter (SL) User Manual
Introduction
Dual-zone or multi-zone climate control: It is quite likely that the Grecale will include a dual-zone or multi-zone climate control system that will let the driver, front passenger, and maybe rear passengers set the temperature to their liking. You can expect to see controls for adjusting the temperature, often in the form of knobs, buttons, or a touchscreen interface. You can choose your side of the car’s desired temperature with these controls. Using the air conditioning controls, you should be able to change the fan speed to increase or decrease the quantity of airflow inside the cabin. You can often control the airflow’s direction by selecting floor vents, face vents, or a mix of the two.
In order to encourage cautious driving and respect to posted speed restrictions, speed limiters might be very helpful. They can decrease the likelihood of accidents, increase fuel efficiency, and make driving more comfortable by limiting excessive speeds. Commercial vehicles and fleet management systems frequently use speed limiters to maintain regulatory compliance and improve overall safety. It’s important to note that specific information about the Maserati Grecale 2023’s speed limiter features, such as its capabilities or precise implementation, would require the most recent data from Maserati or official sources. For exact information on the Grecale model’s speed restriction features, it is advised to refer to the most recent official literature or to Maserati directly.
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 maneuvers. 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 disengaged). The set limit is not deleted (see paragraph “Temporary Deactivation” in this chapter)
Displayed Information
Apart from the pop-up messages at the center 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 canceled 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.
Speed Range of Use
| Speed | mph (km/h) |
| Minimum | 0 |
| Engaged/activated | 18 (30) |
| Maximum | 155 (250) |
Setting
Turn on the SL function when the vehicle has reached the desidered speed, push the button (SET-) and the system sets and visualizes beside the green light the current speed limit (in the example shown 30 mph).
Pushing the button (SET +) or (SET -) once, or long pressing it will enable to increase or decrease the set speed by one unit (1 mph or 1 km/h). If the car is equipped with ADAS Systems, the short press of the button will increase or decrease the set speed of 1 mph or 1 km/h; a long pressure of the same will increase or decrease the set speed of 5 mph or 10 km/h. Release the button when the desired speed is reached, and the new set speed will be visualized beside the green light. The set speed memory can only be erased by pressing the ON/OFF button or by turning the ignition off.
Temporary Deactivation
A press of the button (CANC), with SL function on, erases temporarily the set speed memory, that will remain displayed beside the white light.
Pushing the button (SET +) or (SET -) once, or long pressing it will enable to increase or decrease the set speed by one unit (1 mph or 1 km/h). To resume the set speed, read the next paragraph.
Resume Speed
To resume a previously set speed, push the button (RES) and release it. If you resume the set speed, but driving at a higher speed, the message shown in the picture below appears on the display and a buzzer alerts the driver.
The system cuts the engine torque and the green light with beside the set speed will turn on.
Drive Override
If the driver presses the accelerator pedal to overtake another vehicle and exceeds the set speed limit, the set speed and the green light will blink until the speed returns below the set speed. It is possible to do so at any driving speed, considering that it is possible to set a minimum speed of 18 mph (30 km/h).
Intelligent Speed Assist – ISA (OPT )
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 5 mph or 10 km/h above the speed limit sign detected by the system, or the speed decrement to which the ISA system will adjust, down to a minimum of 5 mph or 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.
FAQs
- What is a Speed Limiter (SL)?
A speed limiter (SL) is a tool or system used to cap the top speed of a car and keep it from going over a set limit. - How does a Speed Limiter work?
In order to monitor the vehicle’s speed, a speed limiter typically uses sensors. When the predetermined speed limit is reached, the limiter intervenes to keep the vehicle’s speed below the limit by reducing engine power or applying force to the brakes. - Why would I need a Speed Limiter?
A speed limiter can be helpful for a number of reasons, such as enhancing road safety by ensuring that cars don’t go faster than the posted speed limit, lowering fuel consumption, and reducing wear and tear on the car. - Can I override or disable the Speed Limiter?
Depending on the particular vehicle and system, a Speed Limiter may be overridden or disabled. Although there may occasionally be a method or device to either temporarily or permanently disable the limiter, doing so is generally not recommended for safety reasons. - Is a Speed Limiter the same as a Cruise Control system?
No, a cruise control system is not the same as a speed limiter. A speed limiter limits the vehicle’s top speed and stops it from exceeding a predetermined limit, whereas cruise control allows the driver to set and maintain a desired speed. - Can I adjust the Speed Limiter’s set speed?
The set speed of a speed limiter can usually be changed by the driver. Usually, the adjustment is made using options or settings found in the dashboard of the car. - Are Speed Limiters standard in all vehicles?
Not all cars come equipped with speed limiters as standard. The vehicle manufacturer and local laws determine their accessibility and inclusion. - Can I set different speed limits for different driving conditions?
The particular Speed Limiter system will determine whether it is possible to set various speed limits for various driving circumstances. This feature may be available on some cutting-edge systems, enabling drivers to change the speed limit according to their preferences or the particular road conditions. - Can I use the Speed Limiter to set a minimum speed limit?
The main purpose of speed limiters is to prevent vehicles from traveling faster than the limits allowed. Setting a minimum speed restriction is not a Speed Limiter’s typical job. - Is a Speed Limiter the same as a Speedometer?
A speedometer and a speed limiter are two distinct parts. A speedometer is a device that shows the vehicle’s current speed, whereas a speed limiter is a device that caps the top speed. - Can I use the Speed Limiter to monitor the driving behavior of others?
A speed limiter’s main function is to control the vehicle it is installed in’s speed. It is not meant to keep an eye on or regulate other people’s driving habits. - Are Speed Limiters adjustable while driving?
Depending on the system and vehicle, a speed limiter may or may not be able to be changed while driving. While some systems might permit adjustments while the vehicle is moving, others might need the car to be stopped for safety reasons. - Can a Speed Limiter be retrofitted into older vehicles?
Older vehicles may be able to retrofit a Speed Limiter, but it depends on a number of variables, including the compatibility of the vehicle and the availability of suitable aftermarket systems. For questions about retrofitting, speaking with an automotive expert or authorized dealer is advised.
