1 Vehicle maintenance and periodic battery checks
The specifics on the maintenance of the vehicles in stock are reported as usual in the dedicated
circular letter, which undergoes periodic updates (See MAS004488 MCL 25-15 MGNT And MAINT Of
Instock Vehicles or newer for details.) In particular, the new Maserati GranTurismo features require
more restrictive 12V battery charge status control logistics than other models in the Maserati family.
The checks involve:
-

Performing a Battery test using the E-XTEQ MAXIMUS at PDI.
Performing a Battery test using the E-XTEQ MAXIMUS during the entire storage period.

1.1

12V Battery Inspection at PDI

Performing a Battery test following the procedures outlined in bulletin “MAS004655 MCL 25-21
Battery Policy for “E-XTEQ” Maximus charger tester (Or Newer)”.

1.2 Check/ restore 12V battery State Of Charge (SOC)

Contents

The following chapter includes a list of best practices and technical notes for Maserati Grecale
Service; this vehicle’s features require precautions that may otherwise not be noticed or highlighted
While the car is undergoing normal operations in the workshop.

2.1 Lifting the vehicle
The position of the lifting points is indicated by an inverted triangle stamped on the edge of the
body; there are also vehicle side pads for interfacing the axle positioning.

Front pad

Rear pad

Be careful about the axle geometry to prevent damaging the vehicle during the lifting operation. We
recommend removing all possible loads from the vehicle (passengers, luggage, spare tire, etc.) to
increase the distance from the ground (in case there are no air springs ).

We recommend using lift plates with a diameter no greater than 125mm for the front axle and
centering the plate on the lifting dowel as well as possible to prevent contact with the car’s floor trim.

Transmission Park Release

If you need to move the car with the engine off, the “Car Wash” mode can be activated.
As shown below:

Put the transmission in N (Neutral) by using the control on the dashboard

-

Turn the engine off by pressing the START/STOP button.

The driver’s door must be shut during these steps. This condition must be maintained for about 15
minutes, after which the transmission moves to P (Park).

released manually as follows:
