rized dealer for service.
EVIC Amber Telltale LightsThis area will show reconfigurable amber cau-
tion telltales. These telltales include:
•Forward Collision Warning (FCW) OFF
This light warns the driver of a
potential collision with the vehicle
in front and prompts the driver to
take action in order to avoid the
collision. For further information,
refer to “Adaptive Cruise Control
(ACC)” in “Understanding The Features Of Your
Vehicle.”
• Wait To Start Light — Diesel Only
This light will illuminate when the igni-
tion switch is first turned to the RUN
position. Wait until the light turns off
before starting the vehicle. Refer to “Starting
Procedures” in “Starting And Operating”. •
Water In Fuel Indicator — Diesel Only
This light indicates water has col-
lected in the fuel filter and should
be drained immediately. See your
authorized dealer for service.
• Air Suspension Up
The air suspension up telltale will
illuminate when the air suspension
is in use. For further information,
refer to “Starting And Operating”.
• Air Suspension Down
The air suspension down telltale
will illuminate when the air suspen-
sion is in use. For further informa-
tion, refer to “Starting And Operat-
ing”.
• Low Fuel Light
When the fuel level reaches approxi-
mately 3.0 gal (11.0 L) this light will turn
on, and remain on until fuel is added. •
Loose Gascap Indicator
If the vehicle diagnostic system
determines that the fuel filler cap is
loose, improperly installed, or
damaged, a loose gascap indica-
tor will display in the telltale display
area. Tighten the fuel filler cap
properly and press the SELECT button to turn
off the message. If the problem continues, the
message will appear the next time the vehicle is
started.
A loose, improperly installed, or damaged fuel
filler cap may also turn on the Malfunction
Indicator Light (MIL).
• Windshield Washer Fluid Low Indicator
This light will turn on to indicate the
windshield washer fluid is low.
• SERV 4WD
The SERV 4WD light monitors the
electric shift 4WD system. If the
SERV 4WD light stays on or comes
on during driving, it means that the

Materials Added to Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives
are recommended. Using gasolines that have
these additives will help improve fuel economy,
reduce emissions, and maintain vehicle perfor-
mance.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these ma-
terials intended for gum and varnish removal
may contain active solvents or similar ingredi-
ents. These can harm fuel system gasket and
diaphragm materials.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to pre-
vent carbon monoxide poisoning:(Continued)
WARNING!(Continued)
• Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the ve-
hicle is stopped in an open area with the
engine running for more than a short pe-
riod, adjust the ventilation system to force
fresh, outside air into the vehicle.
• Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions re-
paired promptly. Until repaired, drive with
all side windows fully open.
• Keep the liftgate closed when driving your
vehicle to prevent carbon monoxide and
other poisonous exhaust gases from enter-
ing the vehicle.FUEL REQUIREMENTS — DIESEL
ENGINE
Use good quality diesel fuel from a reputable
supplier. For most year-round service, No. 2
diesel fuel, meeting ASTM specification D-975
Grade S15, will provide good performance. If
the vehicle is exposed to extreme cold (below
20° F or -7° C), or is required to operate at
colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or
dilute the No. 2 diesel fuel with 50% No. 1
diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel
filters. This vehicle must only use premium
diesel fuel that meets the requirements of
EN 590. Biodiesel blends that meet EN 590
may also be used.
CAUTION!
The manufacturer requires that you must fuel
this vehicle with Ultra Low Sulfur Highway
Diesel fuel (15 ppm Sulfur maximum) and
prohibits the use of Low Sulfur Highway Die-
sel fuel (500 ppm Sulfur maximum) to avoid
damage to the emissions control system.

CAUTION!
Do not use chemical flushes in your engine oil
as the chemicals can damage your engine.
Such damage is not covered by the New
Vehicle Limited Warranty.
Engine Oil Selection – ACEA Categories
For countries that use the ACEA European Oil
Categories for Service Fill Oils, use engine oils
that meet the requirements of ACEA C3, and
that are approved to MB 229.31 or MB 229.51.
Engine Oil Viscosity – 3.6L Engine
SAE 5W-30 engine oil is recommended for all
operating temperatures. This engine oil im-
proves low temperature starting and vehicle
fuel economy.
The engine oil filler cap also shows the recom-
mended engine oil viscosity for your vehicle.
For information on engine oil filler cap location,
refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information. Engine Oil Viscosity – 5.7L Engine
SAE 5W-20 engine oil is recommended for all
operating temperatures. This engine oil im-
proves low temperature starting and vehicle
fuel economy.
The engine oil filler cap also shows the recom-
mended engine oil viscosity for your vehicle.
For information on engine oil filler cap location,
refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information.
NOTE:
SAE 5W-30 engine oil approved to MB
229.31 or MB 229.51 may be used when SAE
5W-20 engine oil is not available.
Engine Oil – Diesel Engine
Engine Oil Selection
For best performance and maximum protection
under all types of operating conditions, the
manufacturer recommends engine oils that
meet the requirements of Chrysler Material
Standard MS-11106, and that are approved to
Mercedes Benz MB 229.31 or MB 229.51 and
ACEA C3.Engine Oil Viscosity
CAUTION!
Your vehicle is equipped with an advanced
technology Diesel Engine and an emission
device designed to limit Diesel Particulate
Emissions from being released into the atmo-
sphere. The durability of your engine and life
expectancy of this diesel particulate filter
emission device is highly dependent on the
use of the correct engine oil.
SAE 5W-30 Synthetic Low Ash Engine Oil is
recommended for all operating temperatures.
This engine oil improves low temperature start-
ing and vehicle fuel economy.
The engine oil filler cap also shows the recom-
mended engine oil viscosity for your engine.

At Each Stop for Fuel
•Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required. Once a Month
•
Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required.
• Check the fluid levels of the coolant reser-
voir, brake master cylinder, power steering
and transmission (5.7L only) and add as
needed.
• Check all lights and other electrical items for
correct operation. At Each Oil Change
•
Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.

† This maintenance is recommended by the
manufacturer to the owner, but is not required
to maintain emissions warranty.
WARNING!
You can be badly injured working on or around
a motor vehicle. Do only that service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your
vehicle to a competent mechanic.
Maintenance Schedule – Diesel
Engine
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service intervals
that are required to keep your vehicle operating
properly and safely.
The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your dealer-
ship know your vehicle best, and have access
to factory trained information, genuine
MOPARparts, and specially designed elec- tronic and mechanical tools that can help pre-
vent future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.
NOTE:
Under no circumstances should oil change
intervals exceed 12,500 miles (20 000 km) or
12 months, whichever comes first.
At Each Stop for Fuel
•
Check the engine oil level about 15 minutes
after a fully warmed engine is shut off.
