Your vehicle may be equipped with an engine oil change
indicator system. The “Oil Change Required” message will
display in the instrument cluster display for five seconds
after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil change indi-
cator system is duty cycle based, which means the engine
oil change interval may fluctuate, dependent upon your
personal driving style.
Unless reset, this message will continue to display each
time you place the ignition in the ON/RUN position. To
turn off the message temporarily, push and release the OK
button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the fol-
lowing procedure.
Oil Life Reset
1. Without pushing the brake pedal, place the ignition in the ON/RUN mode (do not start the engine).
2. Navigate to Oil Lifesubmenu in Vehicle Info in the
instrument cluster display.
3. Push and hold the OKbutton until the gauge resets to
100%.

Secondary Method For Oil Change Reset Procedure

GETTING TO KNOW YOUR INSTRUMENT PANEL 139

Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust system each time the vehicle is raised for lubrication
or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision
if they have been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch is first turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving,
have the system inspected at an authorized dealer as
soon as possible. After the bulb check, this light will
illuminate with a single chime when a fault with the Air
Bag System has been detected. It will stay on until the
fault is removed. If the light comes on intermittently or
remains on while driving, have an authorized dealer
service the vehicle immediately.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See an autho-
rized dealer for service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only
use a floor mat that does not interfere with the operation of
the accelerator, brake or clutch pedals. Only use a floor mat
that is securely attached using the floor mat fasteners so it
cannot slip out of position and interfere with the accelera-
tor, brake or clutch pedals or impair safe operation of your
vehicle in other ways.
246 SAFETY

WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
ENGINE BREAK-IN RECOMMENDATIONS — 3.6L &
5.7L ENGINES
A long break-in period is not required for the drivetrain
(engine, transmission, clutch, and rear axle) in your new
vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
However, wide-open throttle acceleration in low gear can
be detrimental and should be avoided.The engine oil, transmission fluid, and axle lubricant
installed at the factory is high-quality and energy-
conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under
which vehicle operations will occur. For the recommended
viscosity and quality grades, refer to “Fluids And Lubri-
cants” in
Technical Specifications”.

withcaution and maintain a steady controlled speed less than
5 mph (8 km/h) in deep water to minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off),
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing water avoid
depths in excess of 9 inches (23 cm). The flowing water can
erode the streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are downstream
of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 20 inches
(51 cm), and reduce speed appropriately to minimize wave
effects. Maximum speed in 20 inches (51 cm) of water is
less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary.
Refer to “Four-Wheel Drive Operation” in “Starting and
Operating” for further information. Do not shift to a lower
gear than necessary to maintain forward motion. Over-
revving the engine can spin the wheels and traction will be
lost.
Avoid abrupt downshifts on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE: Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.

STARTING AND OPERATING 387

SCHEDULED SERVICING
Scheduled Servicing — Gasoline Engine
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 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), 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) or 350 hours of
engine run time if the vehicle is operated in a dusty and
off-road environment, or is operated predominantly 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, brake
master cylinder and fill as needed.
• Check function of all interior and exterior lights
