Engine Oil Change Indicator System
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil changeindicator 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 turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the MENU button. To reset the oil change indica-
tor system (after performing the scheduled maintenance)
refer to the following procedure.
1. Turn the ignition switch to the ON position (Do not
start the engine).
2. Fully depress the accelerator pedal slowly three times
within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:
If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant, during summer, to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration is recommended. Refer to Fluids, Lubri-
cants, and Genuine Parts in Section 7 for the proper
coolant type.
When using the air conditioner in extremely heavy
traffic, in hot weather, especially when towing a trailer,
additional engine cooling may be required. If this situa-
tion is encountered, operate the transmission in a lower
gear to increase engine RPM, coolant flow and fan speed.
When stopped in heavy traffic, it may be necessary toshift into NEUTRAL and press the accelerator slightly for
fast idle operation to increase coolant flow and fan speed.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other
obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.

release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
onds before trying again.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the heater cord to
a ground-fault interrupter protected 110-115 Volt ACelectrical outlet with a grounded, three-wire extension
cord.
Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
The engine block heater cord is located:
•3.7L Engine — coiled and strapped to the engine oil
dipstick tube.
•5.7L Engine — bundled and fastened to the injector
harness.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 Volt AC electrical cord could
cause electrocution.

CAUTION!
When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering,
as a precaution, and check all fluids afterward. Driv-
ing through water may cause damage that may not be
covered by the new vehicle limited warranty.
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle. If you must
drive through water, try to determine the depth and the
bottom condition (and location of any obstacles) prior to
entering. Proceed with caution 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 in (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 in
(51 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed in 20 in (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 pre-
vent component damage.
262 STARTING AND OPERATING

Life of Tire
The service life of a tire is dependent upon various
factors including but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your
tires. The service description and load identification will
be found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.
300 STARTING AND OPERATING

•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer if the
gasoline contains MMT.
It is even more important to look for gasoline without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
