The main display area will normally display the main
menu or the screens of a selected feature of the main
menu. The main display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. Ex-
amples of this message type are “Right Front Turn Signal
Lamp Out” and “Low Tire Pressure”.
•Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).
•Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition

418 STARTING AND OPERATING

WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
•If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
Clearing A Flooded Engine (Using ENGINE
START/STOP Button)
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather#proce-
dures, it may be flooded. To clear any excess fuel:
1. Press and hold the brake pedal.
2. Press the accelerator pedal all the way to the floor and
hold it.
3. Push and release the ENGINE START/STOP button
once.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release
the accelerator pedal and the brake pedal, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.

STARTING AND OPERATING 425

When you do switch fuel types it is recommended that:
•You do not add less than 5 gallons (19 Liters) when
refueling.
•You drive the vehicle immediately after refueling for at
least 5 miles (8 km).
Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
during warm up.
NOTE:
•Use seasonally adjusted E-85 fuel (ASTM D5798). With
non-seasonally adjusted E-85 fuel, you may experience
hard starting and rough idle following start up even if
the above recommendations are followed, especially
when the ambient temperature is below 32°F (0°C).
•Some additives used in regular gasoline are not fully
compatible with E-85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline
additive, such as MOPAR® Injector Cleanup or
Techron may be used.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) And Gasoline Vehicles
FFV vehicles operated on E-85 require specially formu-
lated engine oils. These special requirements are included
in MOPAR® engine oils, and in equivalent oils meeting
Chrysler Specification MS-6395. The manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex-
tensive fleet testing, to provide additional protection to
Chrysler Group LLC engines. Use MOPAR® or an
equivalent oil meeting the specification MS-6395.
534 STARTING AND OPERATING

American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
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
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Chrysler Material Standard MS-6395.
Engine Oil Viscosity — 3.6L Engine
MOPAR® SAE 5W-20 engine oil approved to Chrysler
Material Standard MS-6395 such as Pennzoil®, Shell
Helix® or equivalent is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the “Engine Com-
partment” illustration in this section.
608 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment. This
type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
•Check engine oil level
•Check windshield washer fluid level
•Check the tire inflation pressures and look for unusual
wear or damage
•Check the fluid levels of the coolant reservoir, brake
master cylinder and power steering, and fill as needed.
•Check function of all interior and exterior lights
