Proceed in reverse order to reassemble the key
fob.
Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.

NOTE:

Once a key fob is programmed to a vehicle, it
cannot be repurposed and reprogrammed to
another vehicle.
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle.Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has never
been programmed.

NOTE:

When having the Engine Immobilizer system
serviced, bring all vehicle keys with you to an
authorized dealer.
Keys must be ordered to the correct key cut to
match the vehicle locks.
For Quadrifoglio models, if you need a
replacement key fob, contact an authorized
dealer.
ENGINE IMMOBILIZER
SYSTEM
The Engine Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed or
activated. Operation is automatic, regardless of
whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation.
Therefore, only key fobs that are programmed to the vehicle can be used to start and operate the
vehicle. The system will shut the engine off in two
seconds if an invalid key fob is used to start the
engine.
After placing the ignition switch in the ON/RUN
position, the Vehicle Security Light will turn on for
three seconds for a bulb check. If the light
remains on after the bulb check, it indicates that
there is a problem with the electronics. In
addition, if the light begins to flash after the bulb
check, it indicates that someone used an invalid
key fob to start the engine. Either of these
conditions will result in the engine being shut off
after two seconds.
If the Vehicle Security Light turns on during
normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there is
a fault in the electronics. Should this occur, have
the vehicle serviced as soon as possible by an
authorized dealer.
All of the key fobs provided with your new vehicle
have been programmed to the vehicle
electronics.

NOTE:
A key fob that has not been programmed is also
considered an invalid key
Ú
page 239.
WARNING!
The integrated key fob contains a coin cell
battery. Do not ingest the battery; there is a
chemical burn hazard. If the coin cell battery
is swallowed, it can cause severe internal
burns in just two hours and can lead to
death.
If you think a battery may have been
swallowed or placed inside any part of the
body, seek immediate medical attention.
Keep new and used batteries away from
children. If the battery compartment does
not close securely, stop using the product
and keep it away from children.
CAUTION!

The battery replacement operation must be done
with care, in order not to damage the key fob.

WARNING!
Always remove the key fobs from the vehicle
and lock all doors when leaving the vehicle
unattended.
Always remember to place the ignition in the
OFF position.
CAUTION!
The Engine Immobilizer system is not
compatible with some aftermarket Remote
Start systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.

Electronic Brake Force Distribution (EBD)
Failure
The simultaneous turning on of the
BRAKE (red) and ABS (amber) warning
lights with the engine on indicates
either a failure of the EBD system or
that the system is not available. In this case, the
rear wheels may suddenly lock and the vehicle
may swerve when braking abruptly.
Oil Temperature Warning Light
This warning light indicates engine oil
temperature is high.
Stop the vehicle and shut off the engine as soon
as possible. If the problem persists, contact an
authorized dealer.
AMBER WARNING LIGHTS
Anti-Lock Brake System (ABS) Warning
Light
This light monitors the ABS. The light will
turn on when the ignition is placed in
the ON/RUN position and may stay on
for as long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is required.
However, the conventional brake system will
continue to operate normally if the red BRAKE
warning light is not on. If the ABS light is on, the brake system should be
serviced as soon as possible to restore the
benefits of Anti-Lock Brakes. If the ABS light does
not turn on when the ignition is placed in the ON/
RUN position, have the light inspected by an
authorized dealer.
Electronic Stability Control (ESC)
Indicator Light — If Equipped
When the ignition is cycled to ON, the
indicator light illuminates, but should
turn off as soon as the engine is started.
ESC System Intervention : Intervention by the
system is indicated by the flashing of the
indicator light: it indicates that the vehicle is in
critical stability and grip conditions.
ESC System Failure: If the indicator light does not
turn off, or if it stays on with the engine running,
a failure was found in the ESC system.
Hill Start Assist System Failure : The illumination
of the indicator light indicates a Hill Start Assist
system failure.
In these cases, contact an authorized dealer as
soon as possible.
Electronic Stability Control (ESC) OFF
Indicator Light — If Equipped
When the ignition is cycled to ON, the
indicator light illuminates, but should
turn off as soon as the engine is started.
The indicator light illuminates to indicate that
some active safety systems have been partially or
totally deactivated

Ú
page 129.
When the active safety systems are reactivated,
the indicator light turns off.
WARNING!
If the warning light does not turn on when the
ignition is placed in the ON/RUN position or
if it stays on when driving (together with the
message on the display), there might be a
malfunction in the restraint systems; This
could mean the air bags or pretensioners
may not deploy in the event of an accident or,
they could deploy erroneously. This could
result in serious injuries or death. Have the
vehicle checked by qualified technician
immediately.
Driving a vehicle with a red brake warning
light on is dangerous. Part of the brake
system may have failed. It will take longer to
stop the vehicle in such circumstances. This
could result in a collision and serious injuries
or death. Have the vehicle checked by a
qualified technician immediately.
WARNING!
Driving a vehicle with a red brake warning light
on is dangerous. Part of the brake system may
have failed. It will take longer to stop the
vehicle in such circumstances. This could
result in a collision and serious injuries or
death. Have the vehicle checked by a qualified
technician immediately.

Tire Pressure Low Warning Light
The indicator light will illuminate to
indicate that the tire pressure is lower
than the recommended value and/or
that slow pressure loss is occurring. In
these cases, optimal tire duration and fuel
consumption may not be guaranteed.
In any situation in which the message on the
display is “See Manual”

Ú
page 142.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that
the tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire duration and fuel consumption may not be
guaranteed.
Should one or more tires be in the condition
mentioned previously, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi
-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
Rear Fog Lights
The indicator illuminates when the rear
fog light is activated.
Engine Check/Malfunction Indicator Light
(MIL)
In normal conditions, when the ignition
is cycled to ON, the indicator light
illuminates, but it should turn off as
soon as the engine is started.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair kit
and contact an authorized dealer as soon as
possible.
WARNING!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor
damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is
recommended that you take your vehicle to an
authorized dealership to have your sensor
function checked.

turns on while the engine is running.
Place the gear selector in the PARK (P) position
and the ignition in the off position: the warning
light should switch off. If the warning light stays
on with engine running, the vehicle can still be
driven.
If the warning light flashes with the engine
running, immediate intervention is required. A
loss of performance, irregular/high idling speed
or engine stopping might take place and the
vehicle may need to be towed.
Contact an authorized dealer as soon as possible
to have the failure eliminated.
Engine Coolant Temperature Too High
The telltale lights up when the engine
has overheated.
In normal driving conditions : stop the
car, turn off the engine and check that the coolant
level in the reservoir is not below the MIN mark.
In this case, wait for the engine to cool down, then
slowly and carefully open the cap, fill with coolant and check that the level is between the MIN and
MAX marks on the reservoir itself. Also check
visually for any fluid leaks. Contact an authorized
dealer if the telltale comes on when the engine is
started again.
If the vehicle is used under demanding conditions
(e.g. in high-performance driving):
slow down
and, if the warning light stays on, stop the vehicle.
Stop for two or three minutes with the engine
running and slightly accelerated to facilitate
better coolant circulation, then turn the engine
off. Check that the coolant level is correct as
described previously.
Hood Cap Not Properly Shut
The telltale turns on when the hood cap
is not properly closed, along with the
icon, an image of the vehicle with an
open hood cap appears on the display.
A buzzer is heard when the hood cap is open and
the vehicle is moving.
Close the hood properly.
Insufficient Engine Oil Level
The telltale turns on, along with the
related message on the display, to
indicate low engine oil level.
Contact an authorized dealer to have the system
checked.
Low Engine Oil Pressure

This telltale indicates low engine oil
pressure. If the telltale turns on while
driving, stop the vehicle and shut off the
engine as soon as possible. A chime will
sound when this telltale turns on. Do not operate
the vehicle until the cause is corrected. This telltale
does not indicate how much oil is in the engine.

CAUTION!
