CAUTION!
Never use Non-Detergent Oil or Straight Min-
eral Oil in the engine or damage may result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as a problem.
SAFETY TIPS
Transporting PassengersNEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
WARNING!
•Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
(Continued)
WARNING!(Continued)
•It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
•Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
•Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They con-
tain carbon monoxide (CO), which is color-
less and odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:

WARNING!(Continued)
•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 con-
trol 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 heat-
ing or cooling controls to force outside air
into the vehicle. Set the blower at high
speed.
The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained 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 a competent mechanic inspect the com-

•The Speedometer shows the vehicle
speed in miles per hour (MPH) and kilo-
meters per hour (km/h).
NOTE:
A chime will sound when the vehicle speed
is above 120 km/h.
Odometer Display / Trip Odometer Dis-
playThis display indicates the total dis-
tance the vehicle has been driven.
2. Tachometer
•This gauge measures engine revolutions
per minute (RPM x 1000). Before the
pointer reaches the red area, ease up on
the accelerator to prevent engine damage.
3. Temperature Gauge
•The temperature gauge shows engine
coolant temperature. Any reading within
the normal range indicates that the engine
cooling system is operating satisfactorily.
•The gauge pointer will likely indicate a
higher temperature when driving in hot
weather or up mountain grades. It shouldnot be allowed to exceed the upper limits
of the normal operating range.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the tempera-
ture gauge reads “H” pull over and stop the
vehicle. Idle the vehicle with the air condi-
tioner turned off until the pointer drops back
into the normal range. If the pointer remains
on the “H”, turn the engine off immediately
and call an authorized dealer for service.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by
steam or boiling coolant. You may want to
call an authorized dealer for service if your
vehicle overheats. If you decide to look un-
der the hood yourself, see “Maintaining Your
Vehicle”. Follow the warnings under the

any mode. The blower
speed increases as you
move the control to the
right from the “O” (OFF)
position. There are
seven blower speeds.
Temperature Control
Rotate this control to
regulate the tempera-
ture of the air inside the
passenger compart-
ment. Rotating the dial
left into the blue area of
the scale indicates
cooler temperatures,
while rotating right into
the red area indicates warmer temperatures.NOTE:
If your air conditioning performance seems
lower than expected, check the front of the
A/C condenser located in front of the radia-
tor for an accumulation of dirt or insects.
Clean with a gentle water spray from behind
the radiator and through the condenser.
Fabric front fascia protectors may reduce
airflow to the condenser, reducing air con-
ditioning performance.
Air Conditioning Control
Push this button to en-
gage the Air Condition-
ing. A light will illuminate
when the Air Condition-
ing system is engaged.
Rotating the dial left into
the blue area of the
scale indicates cooler
temperatures, while ro-
tating right into the red
area indicates warmer temperatures.NOTE:
The air conditioning compressor will not
engage until the engine has been running
for about 10 seconds.

Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. A solution of 50%
OAT (Organic Additive Technology) coolant that
meets the requirements of FCA Material Stan-
dard MS.90032 and 50% water is recom-
mended. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant
selection.
Winter Operation
Use of the air Recirculation Mode during winter
months is not recommended because it may
cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
settings. This will ensure adequate system lu-
brication to minimize the possibility of compres-
sor damage when the system is started again.Window Fogging
Interior fogging on the windshield can be quickly
removed by turning the mode selector to De-
frost. The Defrost/Floor mode can be used to
maintain a clear windshield and provide suffi-
cient heating. If side window fogging becomes a
problem, increase blower speed. Vehicle win-
dows tend to fog on the inside in mild but rainy
or humid weather.
NOTE:
Recirculate without A/C should not be used
for long periods as fogging may occur.
Side Window Demisters
A side window demister outlet is located at each
end of the instrument panel. These non-
adjustable outlets direct air toward the side
windows when the system is in the FLOOR,
MIX, or DEFROST mode. The air is directed at
the area of the windows through which you view
the outside mirrors.Outside Air Intake
Make sure the air intake, located directly in front
of the windshield, is free of obstructions such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the plenum,
they could plug the water drains. In winter
months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter — If Equipped
The A/C Filter prevents most dust and pollen
from entering the cabin. The filter acts on air
coming from outside the vehicle and recircu-
lated air within the passenger compartment.
Refer to “Maintenance Procedures” in “Main-
taining Your Vehicle” for A/C Air Filter service
information or see your authorized dealer for
service. Refer to “Maintenance Schedules” in
“Maintaining Your Vehicle” for filter service inter-
vals.

CAUTION!(Continued)
water. Water can cause permanent damage
to engine, driveline or other vehicle compo-
nents and your brakes will be less effective
once wet and/or muddy.
Before You Cross Any Type Of Water
As you approach any type of water, you need to
determine if you can cross it safely and respon-
sibly. If necessary, get out and walk through the
water or probe it with a stick. You need to be
sure of its depth, approach angle, current and
bottom condition. Be careful of murky or muddy
waters; check for hidden obstacles. Make sure
you will not be intruding on any wildlife, and you
can recover the vehicle if necessary. The key to
a safe crossing is the water depth, current and
bottom conditions. On soft bottoms, the vehicle
will sink in, effectively increasing the water level
on the vehicle. Be sure to consider this when
determining the depth and the ability to safely
cross.Crossing Puddles, Pools, Flooded Areas
Or Other Standing Water
Puddles, pools, flooded or other standing water
areas normally contain murky or muddy waters.
These water types normally contain hidden
obstacles and make it difficult to determine an
accurate water depth, approach angle, and
bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior
to entering. This makes for a faster, cleaner and
easier vehicle recovery. If you are able to deter-
mine you can safely cross, than proceed using
the low and slow method.
CAUTION!
Muddy waters can reduce the cooling sys-
tem effectiveness by depositing debris onto
the radiator.
After Driving Off-RoadOff-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to check
for damage. That way you can get any problemstaken care of right away and have your vehicle
ready when you need it.
•Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, and exhaust system for dam-
age.
•Inspect the radiator for mud and debris and
clean as required.
•Check threaded fasteners for looseness, par-
ticularly on the chassis, drivetrain compo-
nents, steering, and suspension. Retighten
them, if required, and torque to the values
specified in the Service Manual.
•Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.
•After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the radia-
tor, fan, brake rotors, wheels, brake linings,
and axle yokes inspected and cleaned as
soon as possible.

Towing TipsBefore setting out on a trip, practice turning,
stopping and backing the trailer in an area away
from heavy traffic.
Manual Transmission — If Equipped
If using a manual transmission vehicle for trailer
towing, all starts must be in first gear to avoid
excessive clutch slippage.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing.
However, if frequent shifting or changes in
engine speed occur while in DRIVE, use the
AutoStick shift control to manually select a
lower gear ratio.
NOTE:
Using a lower gear ratio while operating the
vehicle under heavy loading conditions, will
improve performance and extend transmis-
sion life by reducing excessive shifting and
heat buildup. This action will also provide
better engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then
change the transmission fluid and filter asspecified for"police, taxi, fleet, or frequent
trailer towing."Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
AutoStick
•When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent downshifts.
For example, choose"4"if the desired speed
can be maintained. Choose"3"or"2"if
needed to maintain the desired speed.
•To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid ex-
tended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
•When using the speed control, if you experi-
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.•Use speed control in flat terrain and with light
loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift the
transmission into NEUTRAL and increase en-
gine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
222

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located
on the instrument panel below the climate
controls.
Push the switch to turn on the Hazard
Warning flasher. When the switch is
activated, all directional turn signals
will flash on and off to warn oncoming traffic of
an emergency. Push the switch a second time
to turn off the Hazard Warning flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled and
it is creating a safety hazard for other motorists.
When you must leave the vehicle to seek assis-
tance, the Hazard Warning flashers will con-
tinue to operate even though the ignition is
placed in the OFF position.
NOTE:
With extended use the Hazard Warning
flashers may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
•On the highways — slow down.
•In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease engine idle speed.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
•If your air conditioner (A/C) is on, turn it
off. The A/C system adds heat to the
engine cooling system and turning the
A/C off can help remove this heat.
•You can also turn the temperature control
to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine cooling system.CAUTION!
Driving with a hot cooling system could dam-
age your vehicle. If the pointer rises to the
H(red) mark, the instrument cluster will
sound a chime. When safe, pull over and
stop the vehicle with the engine at idle. Turn
off the air conditioning and wait until the
pointer drops back into the normal range. If
the pointer remains on theH(red) mark for
more than a minute, turn the engine off
immediately and call for service.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam com-
ing from under the hood, do not open the
hood until the radiator has had time to cool.
Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.

JUMP-STARTING
PROCEDURES
If your vehicle has a discharged battery it can be
jump-started using a set of jumper cables and a
battery in another vehicle or by using a portable
battery booster pack. Jump-starting can be dan-
gerous if done improperly so please follow the
procedures in this section carefully.
NOTE:
When using a portable battery booster pack
follow the manufacturer’s operating instruc-
tions and precautions.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or elec-
trical system may occur.
WARNING!
Do not attempt jump-starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
Preparations For Jump-StartThe battery in your vehicle is located in the front
of the engine compartment below the air intake
duct. To access the battery remove the air
intake duct by turning the two finger screws,
located on the radiator support.
WARNING!
•Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
•Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.

NOTE:
Intentional tampering with emissions con-
trol systems can result in civil penalties
being assessed against you.
In unusual situations involving grossly malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst over-
heating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, includ-
ing a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
•Do not shut off the engine or interrupt the
ignition, when the transmission is in gear and
the vehicle is in motion.
•Do not try to start the engine by pushing or
towing the vehicle.
•Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunction-
ing operating conditions.Cooling System
WARNING!
•When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition switch to the OFF position. The
fan is temperature controlled and can start
at any time the ignition switch is in the ON
position.
•You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine cool-
ant (antifreeze) is dirty or rusty in appearance,
the system should be drained, flushed, and
refilled with fresh engine coolant (antifreeze).Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the coolant recovery bottle tubing for
brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the bottle and radiator.
Inspect the entire system for leaks.
Cooling System – Drain, Flush, And Refill
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
If the engine coolant (antifreeze) is dirty or
contains a considerable amount of sediment,
clean and flush with a reliable cooling system
cleaner. Follow with a thorough rinsing to re-
move all deposits and chemicals. Properly dis-
pose of old engine coolant (antifreeze).
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
