Warning and Indicator Lights on Analogue Instruments
Low Fuel Indicator on Fuel Gauge
The illumination of the red indicator inside the gauge indicates that there are approximately 18 litres (4 UK gal) of fuel in the tank.
If the pointer positions on “0” (beginning of scale) and the fuel reserve indicator flashes, there is a system malfunction. In this case, contact the Service Network to have the system checked.
Telltales on Speedometer
Following telltales are displayed on the fuel level gauge and speedometer, and related messages are visible for 10 seconds on the central sector of the display, unless otherwise indicated. The telltales indicated with (*) are also displayed on the TFT display (see “TFT Display” paragraph in this chapter).
Charging System Warning Light
This warning light shows the status of the electrical charging system. If the light stays on or comes on while driving, turn off some of the vehicle’s non-essential electrical devices or increase engine speed (if at idle). If the charging system warning light remains on, the vehicle is experiencing a problem with the charging system. Require IMMEDIATE service at the Service Network. If jump-starting is required, refer to “Jump Start Procedures” in the section “In an Emergency”. 
Malfunction Indicator Light
The Malfunction Indicator Light (MIL) is part of an on-board diagnostic system that monitors engine and automatic transmission control systems. Under normal conditions, this indicator light should switch on when the key in the ignition switch is in the MAR position and switch off as soon as the engine is started. This is a sign that the indicator light working properly. If the indicator remains lighted up or switches on while driving, there is a failure in the fuel supply/ignition and emission control systems. The failure could cause high exhaust emissions, loss of performance, poor vehicle handling and high consumption levels. Under these conditions, you can proceed slowly without forcing the engine or driving at high speeds. The indicator light will switch off if the problem is solved. The error will be registered by the system in any case.
CAUTION!
- When the key in the ignition switch is in the MAR position and if the indicator light does not switch on or if it switches on while driving, contact the Service Network as soon as possible.
- Prolonged driving with the MIL on could cause damage to the engine control system. It also could affect fuel economy and drivability. If the MIL is flashing, severe catalytic converter damage and power loss will soon occur. Immediate service is required.
Parking Lights Indicator
With the key removed from the ignition switch, it indicates that the parking lights are on.
Transmission Failure Warning Light
Depending on the message displayed it signals:
- a transmission failure. If the failure permits, slowly drive to the nearest Centre of the Service Network;
- a too-high temperature of the transmission oil. In this case, slow down until the temperature goes down to the normal values for use (the warning light goes off).
For further information see the chapter “Automatic Transmission” in the section “Driving”.
CAUTION!
Continuous driving with the transmission temperature warning light illuminated will eventually cause severe transmission damage or failure.
WARNING!
If the transmission temperature warning light is illuminated and you continue operating the vehicle, in some circumstances you could cause the fluid to boil over, come in contact with hot engine or exhaust components and cause a fire.
High Beam Indicator
This indicator lights up when the high beams are switched on or when blinking.
Low Oil Pressure Warning Light
Under normal conditions, the warning light illuminates when the key in the ignition switch is turned to MAR position and goes off as soon as the engine is started. If the warning light stays or turns on while driving, the engine oil pressure is too low. The warning light is combined with a displayed message. In this case, turn the engine off immediately and carry out the necessary checks. Do not operate the vehicle until the problem has been solved. This light does not indicate the oil level. The engine oil level must be checked with the dipstick located under the hood (see “Maintenance Procedures” in the section “Maintenance and Care”). If the problem persists, contact the Service Network.
Headlight On Indicator
This indicator will illuminate when the position lights or headlights are turned on. For further details, see “Lights” in the section “Understanding the Vehicle”.
Left Turn Signal Indicator Light
The indicator lights up when the left direction indicators or the hazard lights are turned on. The indicator light will flash at the same frequency of the turn indicators and is controlled by the left multifunction lever. If the vehicle electronics senses that the vehicle drives for more than 1.6 km (1 mile) with either turn signal on, a continuous sound will alert the driver to turn the signal off. If the indicator flashes at a rapid rate, check for a defective exterior light bulb.
Rear Fog Light Indicator
This indicator lights up when the rear fog lights are switched on.
Tyre Pressure Monitoring Light
This warning light is connected to the Tire Pressure Monitoring System (TPMS). Under normal conditions, the warning light should illuminate when the key in the ignition switch is in MAR position and should go off as soon as the engine is started.
If the warning light remains lit or illuminates while driving, the pressure of one or more tires is too low: the related message will be displayed. If the warning light flashes before it is on, it indicates that the system is temporarily unavailable. This warning light illuminates even when you calibrate the TPMS and remains lit until the system is calibrated.
Please refer to “Tire Pressure Monitoring System (TPMS)” in the section “Driving” for further information.
Telltales on Tachometer
Following telltales are displayed on the tachometer and related messages are visible for 10 seconds on the central sector of the display unless otherwise indicated (see “TFT Display” in this chapter).
Anti-Lock Brake Light
This light, and its related message, indicate possible malfunctions of the Anti-Lock Brake System (ABS). The light will turn on when the key in the ignition switch is in the MAR position and may stay on for 4 seconds. If the ABS light remains lit or turns on while driving, the Anti-Lock portion of the brake system is not functioning and requires service. However, the conventional brake system will continue to operate normally if the
warning light is switched off. If the ABS light turns on while driving, or if it does not switch on when the key in the ignition switch is in the MAR position, please visit as soon as possible a Service Center to restore the Anti-Lock Brakes functions.
Seat Belt Reminder Light
When the key in the ignition switch is in MAR position, the seat belt reminder light will light up for a few seconds as a bulb check. During the bulb check, you will hear an acoustic signal if one or both front seat belts are unbuckled. After the bulb check or while driving, if the driver or front passenger seat belt is unbuckled, together with the acoustic signal the seat belt reminder light will light up.
WARNING!
Maserati urges you to use the seat belts correctly fastened and adjusted at all times. Correct use of seat belts can help reduce the risk of serious injury in the event of an accident. Do not pass seat belts over sharp edges: they could tear. Do not pin anything to the seat belts. This could reduce their initial strength and cause them to tear in the event of a crash.
Refer to “Occupants Restraint Systems” in the section “Before Starting” for further information.
Low Brake Fluid Warning Light
This warning light illuminates when the brake fluid level drops below the minimum level. If accompanied by a specific message, it indicates an EBD system failure. In this case, do not apply the brakes suddenly, since this may cause an early locking of the rear wheels. Driving extremely carefully, immediately go to the nearest Service Network centre to have the system checked.
WARNING!
If the warning light illuminates while driving, immediately check the brake fluid level. If the fluid is below the minimum level, there may be a leakage in the circuit. Contact the Service Network before driving further.
