ECU MASERATI GHIBLI 2019 Service Manual

safety system and is not designed to
prevent accidents.
The ACC allows driver to keep Cruise
Control active in limited or moderate
traffic conditions with no need to
constantly restore the Cruise Control.
The ACC uses a radar sensor, located
on the front grille behind the trident,
and the forward-facing camera behind
the internal rear-view mirror to detect
the presence of a vehicle ahead at a
close distance and moving in the same
direction.
This vehicle, in this chapter, will be
indicated as "target vehicle" or
"vehicle ahead".
NOTE:
• If the sensor detects no vehicle
ahead, the ACC system will maintain
set steady speed.
• If the ACC sensor detects a vehicle ahead, the ACC system automatically
kicks in by slightly accelerating or
braking (to avoid exceeding the
initially set speed) so that the vehicle
keeps present distance, trying to
adapt to the speed of the detected
vehicle ahead.
WARNING!
• The Adaptive Cruise Control (ACC) is
designed to increase vehicle driving
comfort. It must not be considered
as a means of replacing the required
attention of the driver. The driver is
always required to drive carefully.
The driver is always required to pay
utmost attention to driving
conditions (road, traffic, weather)
and style (speed, distance from
sensed vehicle ahead, brake use).
Driver has the full responsibility of
the vehicle therefore his attention is
crucial to keeping vehicle control, in
particular when approaching curves
and situations with heavy traffic.
Failure to follow these warnings can
result in a collision and death or
serious personal injury.
• In some driving scenarios, the ACC
could have detection problems. In
such cases, the ACC could kick in late or unexpectedly. The driver must be
careful since his/her intervention
could be necessary.
• It is always the driver’s responsibility
to obey speed limits and to keep
minimum legal distance to the
preceding vehicle.
• ACC system can decelerate only with
limited braking, it cannot execute
emergency braking.
The ACC system:
•
Does not activate/react in the
presence of pedestrians, bicycles,
incoming traffic from the opposite
direction and steady objects such as a
vehicle stuck in a traffic jam.
• Is meant for the use on highways and
well-built roads, not for city traffic or
mountain roads.
• May not have enough time to react
and/or decelerate sufficiently on
vehicles when lane is changed too
quickly or the relative speed is too
high. In such cases the driver has to
react appropriately and without any
acoustic/visual and warning.
• Cannot consider road, traffic and
weather conditions and might prove
limited when visibility is poor.
• Does not always fully recognize
complex driving conditions and thisDriving

• Pull the release cable moderately to
avoid its possible break. It's not
possible to feel or hear the unlocking
of the fuel filler door actuator.
• Then open normally the fuel filler
door. Driving Conditions Before the Trip Check the following at regular
intervals and always before long trips:
• tire pressure and condition;
• levels of fluids and lubricants;
• conditions of the windshield wiper
blades;
• clean the glass on the external light
and all other glass surfaces;
• proper operation of the indicator
lights and of the external lights.
CAUTION!
It is however advisable to perform
these checks at least every 600 mi
(1000 km) and always following the
maintenance schedule reported in
section “Maintenance and Care”.
Before you drive:
•
adjust seat position, steering wheel,
adjustable pedals (if equipped with)
and rearview mirrors in order to have
the best driving position;
• ensure that nothing (mat covers, etc.)
is obstructing the pedals movement;
• carefully arrange and secure any
objects in the trunk, to prevent them from moving forward in case of
sudden stops;
• avoid heavy meals before a trip. A
light snack helps keep your reflexes
sharp. In particular, avoid drinking
alcohol.
WARNING!
Passengers must only travel seated in
the vehicle seats, with the seat belts
fastened. Always check that the driver
and all passengers have the seat belts
correctly fastened.
Safe Driving Although the vehicle is equipped with
active and passive safety devices, the
driver's conduct is always a decisive
factor for road safety.
Some simple rules for traveling safely
in different conditions are listed
below. Some of them will probably
already sound familiar but, in any case,
it would be useful to read them
carefully.
Driving at Night
The main guidelines to follow when
driving at night are set out below.

Brake Fluid Level Check
Check
the fluid level immediately if
the brake system warning light
(USA) and the related message
turn on indicating a low level of brake
fluid.
• Remove the brake fluid reservoir
access cover. • Clean the top of the master cylinder
reservoir before removing the cap.
• Add fluid to bring the level up to the
“MAX” mark on the side of the
master cylinder reservoir. Use only
manufacturer's recommended brake
fluid (see “Refillings” in section
“Features and Specifications”).
• Once the correct level is reached,
firmly close the cap.
Normal brake pad wear could cause
the fluid level to fall. However, low
fluid level may be caused by a leak
too, and requires accurate checkup of
the braking system.
CAUTION!
The symbol
on the tank cap
identifies the synthetic type of brake
fluid, distinguishing it from the
mineral type. Using mineral fluids damages the special rubber linings of
the brake system irreparably.
WARNING!
• To avoid contamination from foreign
materials or moisture, use only new
brake fluid or fluid that has been in
a tightly closed container. Keep the
master cylinder reservoir cap
secured at all times.
• Overfilling the brake fluid reservoir
can result in spilling brake fluid.
Brake fluid can also damage painted
and vinyl surfaces, make sure it does
not spill over these surfaces.
• Do not allow petroleum based fluid
to contaminate the brake fluid.
Brake seal components could be
damaged.
Adding Washer Fluid
The
reservoir on
the left side of the
engine compartment contains the
fluid to wash the windshield.
During scheduled services or when the
message of low level of the washer
fluid appears together with the
related telltale
add more fluid as
soon as possible.Maintenance and Care
