(Continued)
The engine oil installed in the engine at the
factory is a high-quality energy conserving type
lubricant. Oil changes should be consistent with
anticipated climate conditions under which
vehicle operations will occur. For the recom -
mended viscosity and quality grades, refer to
“Fluids And Lubricants” in “Technical Specifica-
tions”.
NOTE:
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera -
tion. This should be considered a normal part of
the break-in and not interpreted as a problem.
Please check your oil level with the engine oil
indicator often during the break in period. Add
oil as required.PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied.
The parking brake lever is located on the
outboard side of the driver’s seat. To apply the
parking brake, pull the lever up as firmly as
possible. To release the parking brake, pull the
lever up slightly, push the release button with
your thumb, then lower the lever completely.
Parking Brake When the parking brake is applied with the igni
-
tion switch in the MAR (ACC/ON/RUN) position,
the Brake Warning Light in the instrument
cluster will illuminate.
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill
grade and away from the curb on an uphill
grade. The parking brake should always be
applied whenever the driver is not in the vehicle.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.

WARNING!
Never use the PARK position as a substi -
tute for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible
injury or damage.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Leaving
unattended children in a vehicle is
dangerous for a number of reasons. A child
or others could be seriously or fatally
injured.

STARTING AND OPERATING103
Power Steering Fluid Check
Checking the power steering fluid level at a
defined service interval is not required. The fluid
should be checked at every oil change if a leak
is suspected, abnormal noises are apparent,
and/or the system is not functioning as antici -
pated. Coordinate inspection efforts through an
authorized dealer. If necessary, add fluid to restore to the proper
indicated level. With a clean cloth, wipe any
spilled fluid from all surfaces. Refer to “Fluids
And Lubricants” in “Technical Specifications”
for further information.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
25 mph (40 km/h) up to the maximum speed of
100 mph (160 km/h).
The Speed Control lever is located on the left
side of the steering column.
Speed Control Lever NOTE:
In order to ensure proper operation, the Speed
Control system has been designed to shut down
if multiple Speed Control functions are operated
at the same time. If this occurs, the Speed
Control system can be reactivated by rotating
the Speed Control ON/OFF center ring and
resetting the desired vehicle set speed.
To Activate
Rotate the center ring upward on the Speed
Control lever to turn the system on. The Cruise
Indicator Light in the instrument cluster display
will illuminate. To turn the system off, rotate the
center ring upward a second time. The Cruise
Indicator Light will turn off. The system should
be turned off when not in use.WARNING!
Fluid level should be checked on a level
surface and with the engine off to prevent
injury from moving parts and to ensure
accurate fluid level reading. Do not overfill.
Use only manufacturer's recommended
power steering fluid.
CAUTION!
Do not use chemical flushes in your power
steering system as the chemicals can
damage your power steering components.
Such damage is not covered by the New
Vehicle Limited Warranty.
WARNING!
Leaving the Speed Control system on when
not in use is dangerous. You could
accidentally set the system or cause it to go
faster than you want. You could lose control
and have an accident. Always leave the
system off when you are not using it.

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door
on the left side of the vehicle. If the gas cap is
lost or damaged, be sure the replacement cap
is for use with this vehicle.
Fuel Filler
NOTE:
During fuel fill, nozzle position could affect the
flow of fuel. For best results, allow the nozzle to
rest naturally in the filler tube - do not raise the
handle to increase the fill angle. NOTE:When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap until you hear a
“clicking” sound. This is an indication that the
fuel filler cap is properly tightened.
If the gas cap is not tightened properly, the
MIL may come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a “Check fuel cap” message will be
displayed in the instrument cluster display.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information. Tighten the fuel filler cap
until a “clicking” sound is heard. This is an indi
-
cation that the fuel filler cap is properly tight -
ened. Refer to “Onboard Diagnostic System” in
“Getting To Know Your Instrument Panel” for
further information.
If the problem continues, the message will
appear the next time the vehicle is started. See
your authorized dealer as soon as possible.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the
“Malfunction Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu -
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn
on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.

Shallow Standing Water
Although your vehicle is capable of driving
through shallow standing water, consider the
following Cautions and Warnings before doing
so.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
CAUTION!
Always check the depth of the standing
water before driving through it. Never drive
through standing water that is deeper than
the bottom of the tire rims mounted on the
vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when
driving through standing water. This will
minimize wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is
milky or foamy in appearance) after driving
through standing water. Do not continue to
operate the vehicle if any fluid appears
contaminated, as this may result in further
damage. Such damage is not covered by
the New Vehicle Limited Warranty.
Getting water inside your vehicle’s engine
can cause it to lock up and stall out, and
cause serious internal damage to the
engine. Such damage is not covered by the
New Vehicle Limited Warranty.
CAUTION!

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indi-
cator 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 in the
instrument cluster. This means that service is
required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, and
extremely hot or cold ambient temperatures will
influence when the “Oil Change Required”
message is displayed. Severe Operating Condi-
tions can cause the change oil message to illu -
minate as early as 3,500 miles (5,600 km)
since last reset. Have the vehicle serviced as
soon as possible, within the next 500 miles
(805 km). An authorized dealer will reset the oil change
indicator message after completing the sched
-
uled oil change. If a scheduled oil change is
performed by someone other than an autho -
rized dealer, the message can be reset by refer -
ring to the steps described under “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 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 predominately at idle or only very
low engine RPM. 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. Rotate at the
first sign of irregular wear, even if it occurs
before the oil indicator system turns on
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
Maintenance Plan
Required Maintenance Intervals
Refer to the maintenance plan on the following
pages for the required maintenance intervals.

20_VF_OM_EN_US_t.book Page 152

SERVICING AND MAINTENANCE157
Checking Oil Level — Gas Engine
To ensure proper lubrication of your vehicle's
engine, 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 about five
minutes after a fully warmed up engine is shut
off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Always maintain the oil level within
the SAFE zone on the dipstick. Adding one quart
of oil when the reading is at the bottom of the
SAFE zone will result in a reading at the top of
the safe zone on these engines.
Adding Washer Fluid
The fluid reservoir is located in the engine
compartment and should be checked at regular
intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze) and
operate the system for a few seconds to flush
out any residual water.
The washer fluid reservoir will hold a full gallon
of fluid when the Low Washer Fluid Light illumi -
nates.
After the engine has warmed, operate the
defroster for a few minutes to reduce the possi -
bility of smearing or freezing the fluid on the
cold windshield. Mopar All Weather Windshield
Washer Solution or equivalent, used with water
as directed on the container, aids cleaning
action, reduces the freezing point to avoid line
clogging, and is not harmful to paint or trim.
Maintenance-Free Battery
Your vehicle is equipped with a mainte-
nance-free battery. You will never have to add
water, nor is periodic maintenance required.
CAUTION!
Overfilling or underfilling will cause oil
aeration or loss of oil pressure. This could
damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water. Refer to “Jump
Starting Procedure” in “In Case Of Emer -
gency” for further information.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
Battery posts, terminals, and related acces -
sories contain lead and lead compounds.
Wash hands after handling.

192TECHNICAL SPECIFICATIONS
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
Wheel Mounting Surface
Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway).
Torque Patterns After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.
FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all
emissions regulations and provide
optimum fuel economy and perfor-
mance when using high quality
unleaded “Regular” gasoline having a posted
octane number of 87 as specified by the (R+M)/
2 method. The use of higher octane “Premium”
gasoline is not required, as it will not provide
any benefit over “Regular” gasoline in these
engines. While operating on gasoline with an octane
number of 87, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see your dealer immediately.
Use of gasoline with an octane number lower
than 87 can cause engine failure and may void
or not be covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “Refor
-
mulated Gasoline”. Reformulated gasoline
contains oxygenates and are specifically
blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recom -
mended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully
until the vehicle has been lowered. Failure to
follow this warning may result in personal
injury.
