Maintenance-Free Battery
This vehicle is equipped with a sealed
type maintenance-free battery. You
will never have to add water, nor is
periodic maintenance required.
WARNING!
•Battery fluid is a corrosive acid
solution and can burn or damage
the eyes. Do not allow battery fluid
to contact your eyes, skin, or
clothing. Do not lean with the face
over a battery. If acid splashes in
eyes or on skin, flush the area
immediately with large amounts of
water.
•Battery gas is flammable and
explosive. Keep flame or sparks
away from the battery. Do not use a
booster battery or any other booster
source with an output greater than
12 Volts. Do not allow cable clamps
to touch each other.
•Battery posts, terminals, and related
accessories contain lead and lead
compounds. Wash hands after
handling the battery.
•The battery in this vehicle has a vent
hose that should not be
disconnected and should only bereplaced with a component of the
same type (vented).
To Disconnect the Battery
The battery is fitted in the trunk
compartment.
To access the battery it is necessary to
remove the floor panel of the trunk
compartment and the inside covering
panel on the battery compartment as
already described in the chapter
"Auxiliary Jump-Start Procedure" in
section "In an Emergency".
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

CAUTION!
• Before disconnecting the battery,
open the trunk lid and lower the
windows by about 1.6-2 in (4-5
centimeters), to avoid damaging the
seal when opening and closing the
door. When the battery is connected,
this operation is performed
automatically when the door is
opened and closed. The windows
must remain lowered until the
charged battery is reconnected.
• If you need to disconnect the
battery, wait at least 30 seconds
from the last seat movement. If
disconnecting the battery before,
you will have to run the initialization
procedure described in the following
paragraph “To Reconnect the
Battery”.
• Never disconnect the battery from
the electrical system when the
engine is running.
• To temporarily disconnect the vehicle
electrical system from the battery,
simply remove the cable end with

quick coupling from the negative
pole (–) of the battery.
If the battery needs to be removed
from its compartment, you must first
detach the terminal clamp from
negative pole (–) and then the other
terminal clamp from positive pole (+),
after removing the protective cover.
Battery poles are marked positive (+)
and negative (–) and are identified on
the battery case.
Remove the metal clamp indicated in
the picture and then remove the
battery from the trunk compartment.
To Reconnect the Battery
NOTE:
When the battery cables have been
disconnected and the trunk lid has
been locked, it is necessary to pull the
emergency release cable in order to
re-open it. To access the trunk and
operate the emergency release (see
“Open and Close the Trunk Lid”
chapter in section “Before Starting”).
CAUTION!
• It is essential when replacing the
cables on the battery that the
positive cable is precisely attached to
the positive pole (+) and the
negative cable is attached to the
negative pole (–).
• Cable clamps should be tight on the
terminal poles and free of corrosion.
After the battery has been
disconnected and re-connected and
before starting the engine it is
necessary to proceed as follows:
• Unlock and lock the doors using the
radio control buttons on the key.
• Unlock the trunk lid with the radio
control button on the key and then
lock it manually.• Check the seats are working
correctly: in the event of
malfunction, carry out the
initialization operations described in
the chapter “Front Seats” of the
section “Understanding the Vehicle”.
• Initialize the climate control system
by activating the compressor as
described in chapter "Air
Conditioning Controls" of the section
“Dashboard Instruments and
Controls”.
• Turn on the MTC+ and set the date
and time (see “MTC+ Setting” in
section “Dashboard Instruments and
Controls”).
• Lift, release and lift again the lever
located next the shift lever to
initialize the electric parking brakes.
In this way the
warning light
on the instrument cluster will turn
off.
CAUTION!
• Every time the battery is
reconnected, wait at least 30 seconds
with the key in the ignition switch
turned toMAR (ON)position before
starting the engine, in order to allow
the electronic system that manages

flames are kept well away from the
battery while it is charging.
•Before using a charger to charge or
maintain the battery charge status,
carefully follow the instructions
provided to ensure the charger is
connected to the battery safely and
correctly.
It is possible to recharge the battery
without disconnecting the cables of
the vehicle electrical system.
• To access the battery remove the
floor panel from the trunk
compartment and remove the inside
covering panel on the battery
compartment as previously shown
(see “Auxiliary Jump-Start
Procedure” in section “In an
Emergency”).
• Remove the protection cover and
connect the terminal clamp of the
charger positive cable (typically in
red) to the positive pole (+) of the
battery, indicated in the picture.
• Connect the terminal clamp of the
charger negative cable (typically in
black) to the negative pole (–) of the
battery, indicated in the picture.• Turn the charger on and follow the
instructions on its user manual to
completely recharge the battery.
• When the battery is recharged, turn
off the battery charger before
disconnecting it from the battery.
• Disconnect first the terminal clamp
of the charger black cable from the
battery and then the terminal clamp
of the red cable.
• Reassemble the protection cover on
the battery positive pole and reinstall
the components removed for this
operation.
