— Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low.
— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
This warning light will illuminate when the
ignition is in the ON/RUN position before
engine start. If the bulb does not come on
when turning the ignition switch from OFF to
ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced by an authorized dealer as
soon as possible if this occurs.WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
— AdBlue® (UREA) Injection System
Failure Warning Light — If Equipped
This warning light will illuminate along with a
dedicated message on the display (If
Equipped) if an unknown fluid not conform-
ing with acceptable characteristics is in-
serted, or if an average consumption of
AdBlue
®(UREA) over 50% is detected. Con-
tact an authorized dealer as soon as possible.
If the problem is not solved, a specific mes-
sage will appear on the Instrument Cluster
Display whenever a certain threshold is
reached until it will no longer be possible to
start the engine.
When about 125 mi (200 km) are remaining
before the AdBlue
®tank is empty, a continu-
ous dedicated message will appear on the
instrument panel, accompanied by a buzzer
sound (If Equipped).
SERV4WD— Service 4WD Warning Light — If
Equipped
This warning light will illuminate to signal a
fault with the 4WD system. If the light stays
on or comes on during driving, it means that
the 4WD system is not functioning properlyGETTING TO KNOW YOUR INSTRUMENT PANEL

CAUTION!
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Servicing
And Maintenance” in your Diesel Supple-
ment for further information, which can be
found with your online Owner’s Informa-
tion.
3. The system will automatically engage the
starter to crank the engine. If the vehicle
fails to start, the starter will disengage
automatically after 25 seconds.
4. If you wish to stop the cranking of the
engine prior to the engine starting, push
the button again.
5. Check that the oil pressure warning light
has turned off.
6. Release the parking brake.NOTE:
Only press one pedal at a time while driving
the vehicle. Torque performance of the ve-
hicle could be reduced if both pedals are
pressed at the same time. If pressure is
detected on both pedals simultaneously, a
warning message will display in the instru-
ment cluster. For further information, refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel”.
STOP/START SYSTEM — IF
EQUIPPED
The Stop/Start function is developed to re-
duce fuel consumption. The system will stop
the engine automatically during a vehicle
stop if the required conditions are met. Re-
leasing the brake pedal or pressing the accel-
erator pedal will automatically re-start the
engine.
This vehicle has been upgraded with a heavy
duty starter, enhanced battery, and other up-
graded engine parts, to handle the additional
engine starts.
Automatic Mode
The Stop/Start feature is enabled
after every normal customer en-
gine start. At that time, the sys-
tem will go into STOP/START
READY and if all other conditions are met,
can go into a STOP/START AUTOSTOP AC-
TIVE “Autostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
• The system must be in STOP/START
READY state. A STOP/START READY mes-
sage will be displayed in the instrument
cluster display within the Stop/Start sec-
tion. Refer to “Instrument Cluster” in “Get-
ting To Know Your Instrument Panel” in
your Owner’s Manual for further informa-
tion.
• The vehicle must be completely stopped.
• The shifter must be in a forward gear and
the brake pedal depressed.
STARTING AND OPERATING
150

This wearing in occurs mainly during the first
500 miles (805 km) and continues through
the first oil change interval.
It is recommended for the operator to observe
the following driving behaviors during the
new vehicle break-in period:
0 to 100 miles (0 to 161 km):
• Do not allow the engine to operate at idle
for an extended period of time.
• Depress the accelerator pedal slowly and
not more than halfway to avoid rapid accel-
eration.
• Avoid aggressive braking.
• Drive with the engine speed less than
3,500 RPM.
• Maintain vehicle speed below 55 mph
(88 km/h) and observe local speed limits.
100 to 300 miles (161 to 483 km):
• Depress the accelerator pedal slowly and
not more than halfway to avoid rapid accel-
eration in lower gears (1st to 3rd gears).
• Avoid aggressive braking.• Drive with the engine speed less than
5,000 RPM.
• Maintain vehicle speed below 70 mph
(112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shifting
manually (paddles or gear shift) at higher
rpms when possible.
• Do not perform sustained operation with
the accelerator pedal at wide open throttle.
• Maintain vehicle speed below 85 mph
(136 km/h) and observe local speed limits.
For the first 1500 miles (2414 km):
• Do not participate in track events, sport
driving schools, or similar activities during
the first 1500 mi (2414 km).
NOTE:
Check engine oil with every refueling and add
if necessary. Oil and fuel consumption may
be higher through the first oil change inter-
val. Running the engine with an oil level
below the add mark can cause severe engine
damage.AUTOMATIC
TRANSMISSION
WARNING!
•Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when exiting the ve-
hicle to guard against vehicle movement
and possible injury or damage.
•Your vehicle could move and injure you and
others if it is not in PARK. Check by trying
to move the transmission gear selector out
of PARK with the brake pedal released.
Make sure the transmission is in PARK
before exiting the vehicle.
•The transmission may not engage PARK if
the vehicle is moving. Always bring the
vehicle to a complete stop before shifting
to PARK, and verify that the transmission
gear position indicator solidly indicates
PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the
PARK position is properly indicated, before
exiting the vehicle.

Your vehicle is equipped with an engine oil
that has been thoroughly developed and
tested in order to meet the requirements of
the Scheduled Servicing Plan. Constant use
of the prescribed lubricants guarantees the
fuel consumption and emission specifica-
tions. Lubricant quality is crucial for engine
operation and duration. If lubricants con-
forming to the specific request are not avail-able, products that meet the indicated speci-
fications can be used to top up, in this case
optimal performance of the engine is not
guaranteed.

FUEL CONSUMPTION AND
CO
2EMISSIONS
The fuel consumption and CO2emission fig-
ures declared by the manufacturer are deter-
mined on the basis of the type-approval tests
laid down by the applicable standards in the
country where the vehicle is registered.
The type of route, traffic conditions, weather
conditions, driving style, general condition of
the vehicle, trim level/equipment/ accesso-
ries, use of the climate control system, ve-
hicle load, presence of roof racks and other
situations that adversely affect the aerody-
namics or wind resistance lead to different
fuel consumption values than those mea-
sured.The fuel consumption will only become more
regular after driving the first 1,864 miles
(3000 km).
To find the specific fuel consumption and
CO
2emission figures for this vehicle, please
refer to the data in the Certificate of Confor-
mity (if equipped), and the related documen-
tation that accompanies the vehicle (if
equipped).
