Warning LightWhat It Means What To Do
TIRE PRESSURE MONITORING INDICATOR LIGHT
The indicator light illuminates 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
above, the display will show the indications
corresponding to each tire in sequence.
Note:
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sudden braking and steering. Repair
immediately using the dedicated tire repair kit and
contact your authorized dealer as soon as possible.
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 Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
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
75

Warning LightWhat It Means What To Do
Caution!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.
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Immediately
restore the correct inflation pressure using the Tire
Repair Kit (refer to “Tire Repair Kit” in “In Case Of
Emergency”) and contact an authorized dealer as soon
as possible.
Tire Pressure Low
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", it is ESSENTIAL to refer to “Driving
Assistance Systems” in “Safety,” strictly complying with
the indications that you find there.

conditions require better traction, the
vehicle automatically goes to AWD
mode.
The driving mode, RWD or AWD, is
shown on the instrument cluster
display.
Note:If the system failure symbol
switches on, after starting the engine or
while driving, it means that the AWD
system is not working properly. If the
warning message activates frequently,
it is recommended to carry out the
maintenance operations.
Electronic Stability
Control (ESC) System
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system uses sensors installed
on the car to determine the path that
the driver intends to follow and
compares it with the car’s effective
path. When the real path deviates from
the desired path, the ESC system
intervenes to counter the vehicle’s
understeer or oversteer.
Oversteer occurs when the car is
turning more than it should according
to the angle of the steering wheel.
Understeer occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.
System Intervention
The intervention of the system is
indicated by the flashing of the ESC
warning light on the instrument panel,
to inform the driver that the vehicle
stability and grip are critical.
Warning!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESC
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
Vehicle modifications, or failure to
properly maintain your vehicle, may change
the handling characteristics of your vehicle,
and may negatively affect the performance
of the ESC system. Changes to the
steering system, suspension, braking system, tire type and size or wheel size
may adversely affect ESC performance.
Improperly inflated and unevenly worn tires
may also degrade ESC performance. Any
vehicle modification or poor vehicle
maintenance that reduces the effectiveness
of the ESC system can increase the risk of
loss of vehicle control, vehicle rollover,
personal injury and death.
Traction Control System
(TCS)
The system automatically operates in
the event of slipping, loss of grip on wet
roads (hydroplaning), and acceleration
on one or both drive wheels on roads
that are slippery, snowy, icy, etc.
Depending on the slipping conditions,
two different control systems are
activated:
If the slipping involves both drive
wheels, the system intervenes, reducing
the power transmitted by the engine.
If the slipping only involves one of the
drive wheels, the Brake Limited
Differential (BLD) function is activated,
automatically braking the wheel which
is slipping (the behavior of a self-locking
differential is simulated). This will
increase the engine torque transferred
to the wheel which isn't slipping.

Caution!
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.
After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which could
damage the TPMS sensor.
INSUFFICIENT TIRE PRESSURE
INDICATION
If an insufficient pressure value is
detected on one or more tires, the
warning light in the instrument
cluster will display alongside the
dedicated messages, the system will
highlight the tire or tires with insufficient
pressure graphically, and an acoustic
signal will be emitted. In this case, stop the car, check the
inflation pressure of each tire, and
inflate the necessary tire or tires to the
correct cold inflation pressure value,
shown on the display or in the
dedicated TPMS menu.
TPMS TEMPORARILY DISABLED
TPMS Check Message
When a system fault is detected, the
“Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds, and
then remain on solid. The system fault
will also sound a chime. If the ignition is
cycled, this sequence will repeat,
provided that the system fault still
exists. The “Tire Pressure Monitoring
Telltale Light” will turn off when the fault
condition no longer exists. A system
fault can occur due to any of the
following:
Jamming due to electronic devices
or driving next to facilities emitting the
same radio frequencies as the TPMS
sensors.
Installing some form of aftermarket
window tinting that affects radio wave
signals.
Lots of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors. After the punctured tire has been
repaired with the original tire sealant
contained in the TireKit, the previous
condition must be restored so that the
warning light is off during normal
driving.
TPMS Deactivation
The TPMS can be deactivated by
replacing all four wheel and tire
assemblies (road tires) with wheel and
tire assemblies that do not have TPMS
Sensors, such as when installing winter
wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first replace all
four wheel and tire assemblies (road
tires) with tires not equipped with Tire
Pressure Monitoring (TPM) Sensors.
Then, drive the vehicle for 10 minutes
above 15 mph (24 km/h). The TPMS
will chime, the "TPM Telltale Light" will
flash on and off for 75 seconds and
then remain on. The instrument cluster
will display the “SERVICE TPM
SYSTEM” message and then display
dashes (--) in place of the pressure
values.
Beginning with the next ignition switch
cycle, the TPMS will no longer chime or
display the “SERVICE TPM SYSTEM”
message in the instrument cluster.
Instead, dashes (--) will remain in place
of the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires)
with tires equipped with TPM sensors.

VEHICLE LOADING
Certification Label
As required by National Highway Traffic
Safety Administration regulations, your
vehicle has a certification label affixed to
the driver's side door or pillar.
This label contains the month and year
of manufacture, Gross Vehicle Weight
Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and
Vehicle Identification Number (VIN). A
Month-Day-Hour (MDH) number is
included on this label and indicates the
Month, Day and Hour of manufacture.
The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating
(GVWR)
The GVWR is the total permissible
weight of your vehicle including driver,
passengers, vehicle, options and cargo.
The label also specifies maximum
capacities of front and rear axle
systems (GAWR). Total load must be
limited so GVWR and front and rear
GAWR are not exceeded.
Payload
The payload of a vehicle is defined as
the allowable load weight a truck can
carry, including the weight of the driver,
all passengers, options and cargo.
Gross Axle Weight Rating
(GAWR)
The GAWR is the maximum permissible
load on the front and rear axles. The
load must be distributed in the cargo
area so that the GAWR of each axle is
not exceeded.
Each axle GAWR is determined by the
components in the system with the
lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles
or suspension components sometimes
specified by purchasers for increased
durability does not necessarily increase
the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification
Label represents the actual tire size on
your vehicle. Replacement tires must be
equal to the load capacity of this tire
size.
Rim Size
This is the rim size that is appropriate
for the tire size listed.
Inflation Pressure
This is the cold tire inflation pressure for
your vehicle for all loading conditions up
to full GAWR.
Curb Weight
The curb weight of a vehicle is defined
as the total weight of the vehicle with all
fluids, including vehicle fuel, at full
capacity conditions, and with no
occupants or cargo loaded into the
vehicle. The front and rear curb weight
values are determined by weighing your
vehicle on a commercial scale before
any occupants or cargo are added.
Loading
The actual total weight and the weight
of the front and rear of your vehicle at
the ground can best be determined by
weighing it when it is loaded and ready
for operation.
The entire vehicle should first be
weighed on a commercial scale to
insure that the GVWR has not been
exceeded. The weight on the front and
rear of the vehicle should then be
determined separately to be sure that
the load is properly distributed over the
front and rear axle. Weighing the vehicle
may show that the GAWR of either the
front or rear axles has been exceeded
but the total load is within the specified
GVWR. If so, weight must be shifted
from front to rear or rear to front as
appropriate until the specified weight
limitations are met. Store the heavier
items down low and be sure that the
weight is distributed equally. Stow all
loose items securely before driving.

Caution!
If a transmission fluid leak occurs, visit your
authorized dealer immediately. Severe
transmission damage may occur. Your
authorized dealer has the proper tools to
adjust the fluid level accurately.
Replacing The Battery
If necessary, replace the battery with
another battery with the same
specifications. It is advised to contact
an authorized dealer for replacement.
Follow the battery manufacturer's
instructions for maintenance.
Note:
It will not be possible to open the trunk
with a key or by pressing the button in
the passenger compartment when the
battery is disconnected. So, always
position the manual trunk opening strap
on the trunk lock before disconnecting
the battery. The procedure is described
in the "Storing The Vehicle" section in
this chapter.
RAISING THE
VEHICLE
If the vehicle requires lifting, visit an
authorized dealer which is equipped
with shop jacks or jack arms.
The vehicle lifting points are marked on
the side skirts with the
symbols.
