Maserati GranTurismo Coupe Owner's Manual page 36

If the minimum brake fluid
level warning light "BRAKE"
switches on, stop the vehicle
immediately and check the brake fluid
level in the tank: if the level is below
the minimum, top it up with the
prescribed fluid and contact your
Authorized Maserati Dealer to have
2 the system checked. In fact, any fluid
leaks from the hydraulic system will
jeopardize the operation of both the
standard braking and the ABS
systems.
36 ABS and EBD systems
The system's performance, in
terms of active safety, must
not lead the driver to take
unecessary futile and unjustified risks.
The vehicle must always be driven
suitably with regard to the weather
and road conditions, visibility and the
traffic.
The maximum deceleration
that can be reached always
depends on the tires' grip on
the road. Obviously, if there is snow or
ice on the road, the grip is greatly
reduced and therefore, in these
conditions the braking distance is
greater, even with the activation of
the ABS system.
