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 lever in order to
re-open it. To access the trunk and
operate the emergency release fold
one of the rear seatbacks (see “Cargo
Area” chapter in section
“Understanding the Vehicle”).
CAUTION!
• It is essential when replacing the
cables on the battery that the
positive cable is attached to the
positive post (+) and the negative
cable is attached to the negative
post (–).
• Cable clamps should be tight on the
terminal posts 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
Key fob RKE Transmitter.
• Close manually the boot lid, unlock it
with the key fob RKE transmitter and
then lock it manually one more time. If the vehicle is equipped with Power
Boot Lid/Hand Free, manually
perform the complete closure. Then
move the lid automatically, using the
buttons on the lid itself, performing
a complete cycle of opening and
closing.
• Initialize the climate control system
by activating the system and pressing
the “AUTO” control as described in
chapter “Air Conditioning Controls”
in section “Dashboard Instruments
and Controls”.
• Turn on the MTC+ and set the date
and time (see “MTC+ Settings” in
section “Dashboard Instruments and
Controls”).
• Lift, release and lift again the lever
on the central console to initialize
the electric parking brake. Following
this operation the
warning light
on the instrument cluster will turn
off.
• For correct activation of the
approach lights on the external
mirrors, press at least once the tilt
button on the driver's door panel so
that the door mode recognizes the
mirrors position. CAUTION!
• Every time the battery is
reconnected, wait at least 30 seconds
with the ignition switch turned to
RUN before starting the engine, in
order to allow the electronic system
that manages the motor-driven
throttles to run a self-learning cycle.
At the same time, you can run the
date and time set up procedure for
the MTC+.
• Every time the battery is reconnected
the warning light
flash for about
10 seconds and then go off.

Useful Advice to Extend
Battery Life When parking the vehicle, make sure
that the doors, front, rear lids and
flaps are properly closed. All interior
lights should be off.
When the engine is turned off, do not
keep the connected devices switched
on for a long time (such as radio,
hazard warning flashers, fan, etc.).
CAUTION!
If the battery charge remains below
50% for a long period of time, it will
be damaged due to sulfation; its
performance and starting power will
be reduced and it will be more subject
to freezing.
We recommend you to have the
battery
charge condition
checked,
preferably at the beginning of the
cold season, to prevent the electrolyte
from freezing. This check should be carried out more
frequently if the vehicle is used mainly
for short trips or if it is equipped with
power-absorbing devices that remain
permanently on even when the
ignition switch is off. This applies
above all if these devices have been
retrofitted ("Aftermarket" services).
If the vehicle is not used for long
periods of time, please see “Vehicle
Stored for Long Periods” in this
section.
Battery Recharge WARNING!
The process of charging or recharging
the battery produces hydrogen, a
flammable gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all
times.
• Before using a charger device
always check that this tool is
suitable for the installed battery,
with constant voltage (lower than
14.0 V) and low amperage
(maximum limit 15 A).
• Recharge the battery in a
well-ventilated environment. • Never charge or recharge a frozen
battery.
• Ensure that any sparks or open
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 lift the ground
coverage of the trunk compartment
and remove the access cover as
previously shown (see paragraph “To
Disconnect the Battery" in this
chapter.
• Remove the protection cover and
connect the terminal clamp of the
charger positive cable (typically in
red) to the positive post (+) of the
battery.
• Connect the terminal clamp of the
charger negative cable (typically in
black) to the nut located by the
negative post (-) on the battery,
indicated in the picture.Maintenance and Care

The vehicle is equipped with an IBS
(Intelligent Battery Sensor) sensor able
to measure charging and discharging
currents and to calculate the state of
charge and state of health of the
battery. This sensor is located at the
negative post (-) of the battery.
For a successful charge/recharge
operation, the charging current must
flow through the IBS sensor as shown
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 post and the
other parts removed for this
operation.
