Cold Weather Operation
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking
when the ambient temperature is less than –22° F (–30° C)
and the oil temperature sensor reading indicates an engine
block heater has not been used. An externally-powered
electric engine block heater is available as optional equip-
ment or from your authorized dealer.
The message “plug in engine heater” will be displayed
in the instrument cluster when the ambient temperature
is below 5° F (–15° C) at the time the engine is shut off
as a reminder to avoid possible crank delays at the next
cold start.
CAUTION!
Use of the recommended SAE 5W-40 synthetic
engine oil and adhering to the prescribed oil change
intervals is important to prevent engine damage
and ensure satisfactory starting in cold conditions.
Extended Park Starting
NOTE:Extended Park condition occurs when the ve-
hicle has not been started or driven for at least 30 days.
1. Install a battery charger or jumper cables to the battery to ensure a full battery charge during the
crank cycle.
2. Cycle the ignition in the START position and release it when the engine starts.
3. If the engine fails to start within 10 to 15 seconds, cycle the ignition to the STOP (OFF/LOCK) position,
wait five seconds to allow the starter to cool, then
repeat the Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least 10 minutes, then repeat
the procedure.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.

Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time
to check the engine oil level is approximately five
minutes after a fully warmed engine is shut off. Do not
check oil level before starting the engine after it has sat
overnight. Checking engine oil level when the engine is
cold will give you an incorrect reading.
Checking the oil while the vehicle is on level ground,
and approximately five minutes after a fully warmed
engine is shut off, will improve the accuracy of the oil
level readings. Maintain the oil level between the range
markings on the dipstick. The safe range is indicated by
a crosshatch zone. Adding 1 quart (0.9 Liters) of oil
when the reading is at the low end of the indicated
range will result in the oil level at the full end of the
indicator range.
CAUTION!
Do not overfill the engine with oil. Overfilling the
engine with oil will cause oil aeration, which can
lead to loss of oil pressure and an increase in oil
temperature. This loss of oil pressure and increased
oil temperature could damage your engine.
Change Engine Oil
The oil change indicator system will remind you that it
is time to take your vehicle in for scheduled mainte-
nance. Refer to the “Maintenance Schedule” for further
information.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), twelve
months or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle time is
generally only a concern for fleet customers.
Engine Oil Selection
For best performance and maximum protection for
turbocharged engines under all types of operating
conditions, the manufacturer recommends synthetic
engine oils that are API Certified and meet the require-
ments of FCA Material Standard MS-12991.

5. Lower the wiper blade and snap the pivot cap intoplace.
Adding Washer Fluid
The windshield washer fluid reservoir is located in the
engine compartment, and the fluid level should be
checked at regular intervals. Fill the reservoir with
windshield washer solvent (not engine coolant/ anti-
freeze). Refer to “Engine Compartment” in this section
for further information.
WARNING!
Commercially available windshield washer sol-
vents are flammable. They could ignite and burn
you. Care must be exercised when filling or work-
ing around the washer solution.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine ex-
haust system.
If you notice a change in the sound of the exhaust
system; or if the exhaust fumes can be detected inside
the vehicle; or when the underside or rear of the vehicle is damaged; have an authorized technician inspect the
complete exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit exhaust
fumes to seep into the passenger compartment. In
addition, have the exhaust system inspected each time
the vehicle is raised for lubrication or oil change.
Replace as required.
WARNING!
•
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you unconscious
and can eventually poison you. To avoid breath-
ing CO, refer to “Safety Tips/Exhaust Gas” in
“Things To Know Before Starting Your Vehicle”
for further information.
• A hot exhaust system can start a fire if you park
over materials that can burn. Such materials
might be grass or leaves coming into contact with
your exhaust system. Do not park or operate your
vehicle in areas where your exhaust system can
contact anything that can burn.7

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
service is required for your vehicle. Operating condi-
tions such as frequent short-trips, trailer tow, extremely
hot or cold ambient temperatures, and E85 fuel usage
will influence when the “Change Oil” message is dis-
played. 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 indica-
tor message after completing the scheduled oil change.
If a scheduled oil change is performed by someone
other than your authorized dealer, the message can be
reset by referring to the steps described under “Instru-
ment Cluster Display” in “Understanding Your Instru-
ment Panel” for further information.NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), twelve
months or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle time is
generally only a concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the
vehicle is operated in a dusty and off road environment
or is operated predominately at idle or only very low
engine RPM’s. 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 and brake
master cylinder as needed.
Check function of all interior and exterior lights.
