Amber Warning Lights
Warning LightWhat It Means What To Do
ANTI-LOCK BRAKE (ABS) INDICATOR LIGHT
This light monitors the Anti-Lock Brake System (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 brake indicator 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.Drive carefully and contact an authorized dealer as soon as
possible.
TIRE PRESSURE MONITORING INDICATOR 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
above, the display will show the indications corresponding
to each tire in sequence.
Continue driving for up to 50 miles (80 km) at a speed no
higher then 50 mph (80 km/h). Contact an authorized dealer
to have the tire repaired.

GETTING TO KNOW YOUR INSTRUMENT PANEL

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 pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation 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
under-inflation 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 approximately 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.
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.
69

Warning LightWhat It Means What To Do
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 “Auxiliary
Driving Systems” in “Safety,” strictly complying with the
indications that you find there.
ELECTRONIC STABILITY CONTROL (ESC) INDICATOR
LIGHT
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. In these cases, contact an authorized dealer as soon as
possible.
Hill Start Assist System Failure : The illumination of the
indicator light indicates a Hill Start Assist system failure.

GETTING TO KNOW YOUR INSTRUMENT PANEL

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 20 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.
Then, drive the vehicle for up to
20 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 turn off. The instrument cluster will
display the “SERVICE TPM SYSTEM”
message and then display pressure
values in place of the dashes. On the next ignition switch cycle the "SERVICE TPM
SYSTEM" message will no longer be
displayed, as long as no system fault
exists.
Note:
The TPMS is not intended to replace
normal tire care and maintenance, or to
provide warning of a tire failure or
condition.
The TPMS should not be used as a
tire pressure gauge while adjusting your
tire pressure.
Driving on a significantly
underinflated tire will cause 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.
The TPMS is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain
correct tire pressure using an accurate
tire pressure gauge, even if
underinflation has not reached the level
to trigger illumination of the “Tire
Pressure Monitoring Telltale Light”.
Seasonal temperature changes will
affect tire pressure, and the TPMS will
monitor the actual tire pressure in the
tire.

Tires
Examine tires for excessive tread wear
and uneven wear patterns. Check for
stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect
the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness.
Check the tires (including spare) for
proper cold inflation pressure.
Lights
Have someone observe the operation of
brake lights and exterior lights while you
work the controls. Check turn signal and
high beam indicator lights on the
instrument panel.
Door Latches
Check for proper closing, latching, and
locking.
Fluid Leaks
Check area under the vehicle after
overnight parking for fuel, coolant, oil, or
other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid
leaks are suspected. The cause should be
located and corrected immediately.
Warning!
To prevent SERIOUS INJURY or DEATH when
using “Track-Use” parts and equipment:
NEVER use any “Track-Use” equipment on
public roads. FCA US LLC does not authorize
the use of “Track-Use” equipment on public
roads.
The intended use of “Track-Use” parts is
for race vehicles on race tracks. To help
ensure the safety of the race driver,
engineers should supervise the installation
of “Track-Use” parts.
FCA US LLC does not authorize the
installation or use of any part noted as
“Track-Use” on any new vehicle prior to its
first retail sale.
Warning!
To prevent SERIOUS INJURY or DEATH:ALWAYS remove any “Track-Use”
equipment before driving on public roads.
ALWAYS properly use your three-point
seat belts when driving on public roads.
In a collision, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the
interior of your vehicle or other passengers,
or you can be thrown out of the vehicle.
129

Warning!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the MIL to
turn on.
A fire may result if gasoline is pumped
into a portable container that is inside of a
vehicle. You could be burned. Always place
gas containers on the ground while filling.
Note: If the filler compartment is
washed with a pressure washer, keep it at
a distance of at least 8 inches (20 cm).
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.

STARTING AND OPERATING

SUGGESTIONS FOR DRIVING
Saving Fuel
Below are some suggestions which may
help you save fuel and lower the amount
of harmful emissions released into the
atmosphere.
Vehicle Maintenance
Checks and operations should be carried
out in accordance with the Maintenance
Plan. Refer to "Scheduled Servicing" in
"Servicing And Maintenance" for further
information.
Tires
Check the tire pressures at least once
every four weeks: if the pressure is too
low, consumption levels increase as
resistance to rolling is higher.
Unnecessary Loads
Do not travel with an overloaded trunk.
The weight of the vehicle and its
arrangement greatly affect fuel
consumption and stability.
Electric Devices
Use electrical systems only for the
amount of time needed. The rear window
defroster, additional headlights,
windshield wipers and heater blower fan
require a considerable amount of energy;
increasing the current uptake increases
fuel consumption (by up to +25% when
city driving).Climate Control System
Using the climate control system will
increase consumption: use standard
ventilation when the temperature
outside permits.
Devices for Aerodynamic Control
The use of non-certified devices for
aerodynamic control may adversely
affect air drag and consumption levels.
Driving Style
Starting
Do not warm up the engine at low or high
revs when the vehicle is stationary; this
causes the engine to warm up more
slowly, thereby increasing fuel
consumption and emissions. It is
therefore advisable to drive off
immediately, slowly, avoiding high
speeds: by doing this the engine will
warm up more quickly.
Unnecessary Actions
Avoid revving up when starting at traffic
lights or before stopping the engine.
This action is unnecessary and causes
increased fuel consumption and pollution.
Gear Selection
Use a high gear when traffic and road
conditions allow it. Using a low gear for
faster acceleration will increase fuel
consumption. Improper use of a high gear
increases consumption, emissions and
engine wear.Max. Speed
Fuel consumption considerably increases
as speed increases. Maintain a constant
speed, avoiding unnecessary braking and
acceleration, which cost in terms of both
fuel consumption and emissions.
Acceleration
Accelerating violently severely affects
consumption and emissions: acceleration
should be gradual and should not exceed
the maximum torque.
Conditions Of Use
Cold Starting
Short trips and frequent cold starts will
not allow the engine to reach optimum
operating temperature. This results in a
significant increase in consumption
levels (from +15 to +30% in city driving)
and emissions.
Traffic And Road Conditions
High fuel consumption is caused by heavy
traffic, for instance when travelling in
traffic with frequent use of low gears or
in cities with many traffic lights. Winding
mountain roads and rough road surfaces
also adversely affect consumption.
Stops In Traffic
During prolonged stops (e.g. railway
crossings) turn off the engine.

a series of checks and services for your
vehicle at fixed intervals based on
distance and time, as described in the
Scheduled Servicing Plan.
Before each service, it is always
necessary to carefully follow the
instructions in the Scheduled Servicing
Plan (e.g. periodically check level of
fluids, tire pressure, etc.).
Scheduled Servicing is offered by an
authorized dealer according to a set time
schedule. If, during each operation, in
addition to the ones scheduled, the need
arises for further replacements or
repairs, these may be carried out with the
owner’s explicit consent only.
Note:Scheduled Servicing intervals are
required by the Manufacturer. Failure to
have them carried out may invalidate the
New Vehicle Limited Warranty.
You are advised to inform your
authorized dealer of any small operating
irregularities without waiting for the next
service.
Periodic Checks

( 1,000 km) or before long trips check
and, if necessary, top off:
Engine coolant level.
Brake fluid level (if insufficient, see an
authorized dealer as soon as possible).
Windshield washer fluid level.
Tire inflation pressure and condition.
Operation of lighting system
(headlights, direction indicators, hazard
warning lights, etc.).
Operation of windshield
washing/wiping system and
positioning/wear of wiper blades.
Every 2,000 miles ( 3,000km), check and
top off if required:
Engine oil level.
Heavy Usage Of The Vehicle
If the vehicle is used under one of the
following conditions:
Dusty roads.
Short, repeated journeys less than
4 miles (7-8 km) at sub-zero outside
temperatures.
Engine often idling or driving long
distances at low speeds or long periods
of inactivity.
In the event of a long period of inactivity.
The following checks must be carried out
more often than indicated in the
Scheduled Servicing Plan:
Check cleanliness of hood and trunk
locks, cleanliness and lubrication of
linkage.
Visually inspect conditions of: engine,
transmission, pipes and hoses
(exhaust/fuel system/brakes) and rubber
elements (sleeves/bushes, etc.).
Check battery charge and battery fluid
level (electrolyte).

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential
to the safe and satisfactory operation of
your vehicle. Four primary areas are
affected by improper tire pressure:
Safety and Vehicle Stability
Economy
Tread Wear
Ride Comfort
Safety
Warning!
Improperly inflated tires are dangerous
and can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result in
tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
Both under-inflation and over-inflation
affect the stability of the vehicle and can
produce a feeling of sluggish response or
over responsiveness in the steering.
Note:
Unequal tire pressures from side to
side may cause erratic and
unpredictable steering response.
Unequal tire pressure from side to
side may cause the vehicle to drift left or
right.
Fuel Economy
Underinflated tires will increase tire
rolling resistance resulting in higher fuel
consumption.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and
reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the driver's side B-Pillar or rear
edge of the driver's side door.
At least once a month:
Check and adjust tire pressure with a
good quality pocket-type pressure gauge.
Do not make a visual judgement when
determining proper inflation. Tires may
look properly inflated even when they are
under-inflated.
Inspect tires for signs of tire wear or
visible damage.
Caution!
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 valve stem.
Inflation pressures specified on the
placard are always “cold tire inflation
pressure”. Cold tire inflation pressure is
defined as the tire pressure after the
vehicle has not been driven for at least
three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of
three hours. The cold tire inflation
pressure must not exceed the maximum
inflation pressure molded into the tire
sidewall.
