CHANGE ENGINE OIL — IF EQUIPPED
Your vehicle is equipped with an engine oil
change indicator system. The “Change Engine
Oil” message will display in the instrument
cluster display. The engine oil change indicator
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, push and release the
MODE
button . To reset the oil change indicator 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 push 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.

Brake Warning Light, which will turn on when
the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Electronic
Brake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn
on along with the ABS Light. Immediate repair to
the ABS system is required. Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two
seconds. The light should then turn off unless
the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
Vehicle Security Warning Light — If
Equipped
This light will flash at a fast rate for
approximately 15 seconds when the
vehicle security system is arming, and
then will flash slowly until the vehicle
is disarmed.
YELLOW WARNING LIGHTS
Immobilizer Fail / VPS Electrical Alarm
Indicator Light
This telltale will illuminate when the
vehicle security system system has
detected an attempt to break into the
vehicle.
NOTE:
After cycling the ignition to the ON/RUN posi -
tion, the Vehicle Security Warning Light could
illuminate if a problem with the system is
detected. This condition will result in the engine
being shut off after two seconds.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may
have failed. It will take longer to stop the
vehicle. You could have a collision. Have the
vehicle checked immediately.

58STARTING AND OPERATING
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 cord to a standard 110-115 Volt AC
electrical outlet with a grounded, three-wire
extension cord. The engine block heater must be plugged in at
least one hour to have an adequate warming
effect on the engine.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle) in
your 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. Wide-open throttle
acceleration in low gear can be detrimental and
should be avoided.
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
recommended viscosity and quality grades see
Ú
page 268.
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.
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 Úpage 203.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds
before trying again.
WARNING! (Continued)
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.

21_VF_OM_EN_USC_t.book Page 58

STARTING AND OPERATING67
NOTE:
Increased noise levels at the end of the
steering wheel travel are considered normal
and do not indicate that there is a problem
with the power steering system.
Upon initial start-up in cold weather, the
power steering pump may make noise for a
short amount of time. This is due to the cold,
thick fluid in the steering system. This noise
should be considered normal, and it does not
in any way damage the steering system.
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
anticipated. 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 Ú
page 270.
CRUISE CONTROL — IF EQUIPPED
When engaged, the Cruise 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 Cruise Control lever is located on the left
side of the steering column.

Cruise Control Lever

NOTE:
In order to ensure proper operation, the Cruise
Control system has been designed to shut down
if multiple Cruise Control functions are operated
at the same time. If this occurs, the Cruise
Control system can be reactivated by rotating
the Cruise Control ON/OFF center ring and
resetting the desired vehicle set speed.
CAUTION!
Prolonged operation of the steering system at
the end of the steering wheel travel will
increase the steering fluid temperature and it
should be avoided when possible. Damage to
the power steering pump may occur.
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 FCA 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.

Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause
should be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
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 an authorized dealer 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, inspect the exhaust system each time
the vehicle is raised for lubrication or oil
change. Replace as required.
CARBON MONOXIDE WARNINGS
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 breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at
high speed.
WARNING! (Continued)
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
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 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
Conditions can cause the change oil message to
illuminate 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
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, the message can be reset by
referring to the steps described under
Instrument Cluster Display Ú
page 45.
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

Vehicles that are operated in a dusty and off-road
environment, or predominately at idle or very low
engine RPM are known as Severe Duty vehicles.
It is recommended that you change the engine oil
at 4,000 miles (6,500 km) or 350 hours of
engine run time.

Once A Month Or Before A Long Trip:
Check engine oil level
Check windshield washer fluid level
Check the tire 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

areas and very short trip driving. In some extreme conditions, additional maintenance not specified in the maintenance schedule may be required.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter.
Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
Inspect battery and clean and tighten terminals as required.
Inspect the CV/Universal joints.
Inspect brake pads, shoes, rotors, drums, hoses and park brake.
Inspect engine cooling system protection and hoses.
Inspect exhaust system.
Inspect engine air cleaner if using in dusty or off-road conditions.
Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty
conditions.
