2020 MASERATI GRANTURISMO auxiliary battery

Engine Start Failure
CAUTION!
• Do not attempt to push or tow your
vehicle to get it started. Vehicles
equipped with an automatic
transmission cannot be started this
way.
• If the vehicle battery is dead, booster
cables may be used to obtain a start
from a booster battery or the
battery in another vehicle. This type
of start can be dangerous if done
improperly. See “Auxiliary Jump
Start Procedure” in section “In an
Emergency” for further information.
Starting by cold engine
Start-off slowly, avoiding sudden
acceleration and rev the engine up at
low medium speeds. High-
performance driving should be
avoided until the engine temperature
reaches 65-70°C (149-158°F).
Engine Turn-Off
• Place the shift lever in P (Park) (see
“Automatic Transmission” in this
section).
• With the engine at idle, turn the key
in the ignition switch toSTOP (OFF)position. A burst on the accelerator
pedal before turning off the engine
has no purpose and increases fuel
consumption.
WARNING!
Never leave a vehicle out of the P
(Park) position, as it could move.
The key can only be removed from the
ignition switch when the transmission
is in P (Park) position and within 30
seconds after turning the key toSTOP
(OFF)position. If you do not remove
the key within 30 seconds, you will
need to turn it back toMAR (ON)and
then toSTOP (OFF)position to have a
further 30 seconds within which to
remove the key from the ignition
switch.
In the event that the key unlocking
system fails or if it is not possible to
shift the transmission to P (Park)
position, to remove the key you must
turn it toSTOP (OFF)position, then
remove the cap shown in picture using
a pen or sufficiently pointed tool.
Then press the button just uncovered
and at the same time extract the key
from the ignition switch. Once the key
has been removed, refit the removed
cap.

emergency starting, only use an
auxiliary battery.
• While driving, if the engine does not
run smoothly, you may continue
driving but reducing engine
performance to a minimum; you
should then contact theAuthorized
Maserati Dealeras soon as possible.
• Never run the engine, even if only
for testing, with one or more spark
plugs disconnected.
• Do not warm up the engine letting it
idle before starting off, except in the
event that the external temperature
is very low and, even then, for no
longer than 30 seconds.
Catalytic Converter Warnings
During normal operation the catalytic
converter produces high temperatures.
Failure to comply with following rules
can create fire hazards.
• Do not park the vehicle on
flammable materials (e.g. grass, dry
leaves, pine needles, etc.).
• Do not install heat guards and do
not remove those already fitted to
the catalytic converter and to the
exhaust manifold.
• Do not spray anything on the
catalytic converter, Oxygen sensor
and exhaust manifold.In addition to the catalytic converter
system, the vehicles are equipped with
a system for controlling fuel vapor
emissions. This system, called ORVR,
has been designed to help reduce
atmospheric pollution by the
evaporation from the fuel system
during the refueling process. Also,
specific to these vehicles is the fuel
filler neck which comes equipped with
a sealed plug that is grounded to
avoid possible sparking during
re-fueling.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more
information go to:www.P65Warnings.ca.gov/passenger-
vehicle
Other Tips
• Do not warm up the engine when
the vehicle is stationary: in these
conditions the engine heats up much
more slowly, thus increasing fuel
consumption and emissions. It is
advisable to move off slowly,
avoiding high engine rpm.
• As soon as traffic conditions and the
route permit it, use a higher gear.
• Avoid depressing the accelerator
repeatedly during stops at traffic
lights or before turning off the
engine.
• Keep your speed as regular as
possible, avoiding unnecessary
braking and acceleration, which
cause fuel wastage and strongly
increase exhaust emissions.
• Turn the engine off if the vehicle
remains stationary for a long time.
• Check the tire pressure regularly: if
the pressure is too low, fuel
consumption increases and the tires
are damaged.
• Do not transport unnecessary heavy
objects in the trunk compartment.

Auxiliary Jump-Start
Procedure
If your vehicle has a discharged battery
it can be jump-started using a set of
jumper cables and a battery of another
vehicle or by using a portable battery
booster. It is necessary to have proper
jumper cables in order to connect the
booster battery to the remote posts of
the discharged battery. Booster cables
have usually positive and negative
terminal clamps and are identified by a
different sheath color (red = positive,
black = negative). Maserati provides
on request jumper cables created for
its models and content in a practical
case.
NOTE:
TheAuthorized Maserati Dealercan
provide you with information about
the “Maserati Jumper Cables Kit”,
available in the “Genuine Accessories”
range.
Jump-starting can be dangerous if
done improperly so please follow the
procedures in this section carefully.NOTE:
When using a portable battery booster
pack, follow the battery
manufacturer’s operating instructions
and precautions.
CAUTION!
• To jump start a vehicle do not use a
portable battery, a booster pack or
any other booster source with a
system voltage greater than 14 Volts
or damage to the battery, starter
motor, alternator or electrical system
of the vehicle with the discharged
battery may occur.
• Do not use a battery charger for
emergency starting under any
circumstances. You could damage the
electronic systems, particularly the
control units managing the ignition
and fuel supply functions.
• If the battery is completely
discharged when the windows are
fully raised, open the door with the
utmost care; do not close the door
again until it is possible to lower the
window.
WARNING!
•Using booster packs that have not
been checked, which could therefore
release a too high charging voltage
(higher than 14 V), in extreme
environmental conditions (for
example: closed areas or without
proper ventilation and temperatures
higher than 122°F/50°C or lower
than -4°F/-20°C) create the right
conditions for ignition which could
then cause the battery to explode.
Therefore you shall always perform
jump-starting operations using the
adequate tools and in the best
environmental conditions, taking all
necessary precautions.
•Do not attempt jump-starting if the
discharged battery is frozen. It could
rupture or explode during jump start
and cause personal injury.
•Do not carry out this procedure if
you have not done it before:
incorrect maneuvers can originate
high electrical discharges and even
cause the battery to explode.
•To avoid the risk of explosion or fire,
do not approach the battery with
