SAFETY 267
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nuts/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
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
exhau s

t 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/lift
-
gate/rear doors open, make sure that all
window s
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!
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 “Change Oil” or “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km). An authorized dealer will reset the oil change
indica

tor message after completing the scheduled
oil change.
NOTE:
Under no circumstances should oil change
inter v
als exceed 10,000 miles (16,000 km),
1 year or 350 hours of engine run time, whichever
c omes f

irst. The 350 hours of engine run or idle
time is generally only a concern for fleet
customers.
NOTE:
The Oil Change Indicator will not illuminate under
these
conditions. 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,
and brake master cylinder reservoir, and fill as
needed.
Check function of all interior and exterior lights.

294 SERVICING AND MAINTENANCE
CHECKING OIL LEVEL
To ensure proper engine lubrication, 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 i

mprove the accuracy of the oil level readings.

th arrow on the engine cover.

Oil Cap
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low
end of the range and MAX at the high end of the
range.
Crosshatched zone marked with dimples at the
MIN and the MAX ends of the range.
NOTE:
Always maintain the oil level within the crosshatch
marki n
gs on the dipstick.
Adding 1 quart (1.0 liter) of oil when the reading is
at the
low end of the dipstick range will raise the oil
level to the high end of the range marking.
ADDING WASHER FLUID
The windshield washer fluid reservoir is located in
the engine compartment, and the fluid level should
be checked at regular intervals. Fill the reservoir
with windshield washer solvent (not engine
coolant/ antifreeze) Ú page 293.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free
battery. You will never have to add water, and
periodic maintenance is not required.
1 — Oil Cap/Dipstick Arrow
2 — Engine Cover Arrow
CAUTION!
Overfilling or underfilling the crankcase will
cause 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 Ú page 279.

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 accesso -
ries contain lead and lead compounds. Wash

d s

after handling.

296 SERVICING AND MAINTENANCE
Materials Added To Engine Oil
The manufacturer strongly recommends against
the addition of any additives (other than leak
detection dyes) to the engine oil. Engine oil is an
engineered product and its performance may be
impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used engine
oil and oil filters from your vehicle. Used oil and oil
filters, indiscriminately discarded, can present a
problem to the environment. Contact an
authorized dealer, service station or governmental
agency for advice on how and where used oil and
oil filters can be safely discarded in your area.
ENGINE OIL FILTER
The engine oil filter should be replaced with a new
filter at every engine oil change.
Engine Oil Filter Selection
A full-flow type disposable oil filter should be used
for re p

lacement. The quality of replacement filters
varies considerably. Only high quality Mopar®
certified filters should be used.
ENGINE AIR CLEANER FILTER
For the proper maintenance intervals Ú page 287.
Engine Air Cleaner Filter Selection
The quality of replacement filters varies
consid e

rably. Only high quality Mopar® certified
filters should be used.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
NOTE:
Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi -
tioning system. Some unapproved refrigerants
are fl
ammable and can explode, injuring you.
Other unapproved refrigerants or lubricants can
cause the system to fail, requiring costly repairs.
Refer to the Warranty Information Book for
further warranty information.
Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi -
tioning system. Some unapproved refrigerants
are fl
ammable and can explode, injuring you.
Other unapproved refrigerants or lubricants can
cause the system to fail, requiring costly repairs.
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrig -
erant or any repair requiring lines to be discon -
nected should be done by an experienced
t echni

cian.
WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in the
case of engine backfire. Do not remove the air
induction system (air cleaner, hoses, etc.) unless
such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle
with the air induction system (air cleaner, hoses,
etc.) removed. Failure to do so can result in
serious personal injury.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.

SERVICING AND MAINTENANCE 299
(Continued)
Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
NOTE:
Intentional tampering with emissions control
syste m
s can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfu n

ctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to manufacturer's specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter
damag
e

:
Do not interrupt the ignition when the transmis -
sion is in gear and the vehicle is in motion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition compo -
nents disconnected or removed, such as when
diagn os
tic testing, or for prolonged periods
during very rough idle or malfunctioning oper -
ating conditions.
COOLING SYSTEM
Coolant Checks
Check engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather,
where
applicable). If the engine coolant is dirty or
rusty in appearance, the system should be
drained, flushed and refilled with fresh engine
coolant. 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.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.

Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued operation
of your vehicle with a severe malfunction could
cause the converter to overheat, resulting in
possible damage to the converter and vehicle.

WARNING!
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 open a
cooling system pressure cap when the radi -
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may
start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the igni -
tion to the OFF mode. The fan is temperature
c ontroll

ed and can start at any time the igni -
tion is in the ON mode.
WARNING!

SERVICING AND MAINTENANCE 301
damage. If HOAT and OAT coolant are mixed in
an emergency, have an authorized dealer drain,
flush, and refill with OAT coolant (conforming to
MS.90032) as soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank (if
equipped).
The cap should be inspected and cleaned if there
is an y

accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is
a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent
ingestion by animals or children, do not store
ethylene glycol-based coolant in open containers
or allow it to remain in puddles on the ground,
clean up any ground spills immediately. If ingested
by a child or pet, seek emergency assistance
immediately.
Coolant Level
The coolant expansion bottle provides a quick
visual method for determining that the coolant
level is adequate. With the engine off and cold, the
level of the coolant (antifreeze) in the bottle should
be between the “MAX” and “MIN” lines marked on
the bottle.
As long as the engine operating temperature is
satisf
actory, the coolant bottle need only be
checked once a month.
When additional coolant is needed to maintain the
proper

level, it should be added to the coolant
bottle. Do not overfill.
See an authorized dealer for service.
Cooling System Notes
NOTE:
When the vehicle is stopped after a few miles/kilo -
meters of operation, you may observe vapor
c oming

from the front of the engine compartment.
This is normally a result of moisture from rain,
snow, or high humidity accumulating on the
radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to
enter the radiator.
If an examination of your engine compartment
shows n

o evidence of radiator or hose leaks, the
vehicle may be safely driven. The vapor will soon
dissipate.
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro -
sion protection of your engine which contains
alumi n

um components.
WARNING!
Do not open hot engine cooling system. Never
add engine coolant (antifreeze) when the
engine is overheated. Do not loosen or
remove the cap to cool an overheated engine.
Heat causes pressure to build up in the
cooling system. To prevent scalding or injury,
do not remove the pressure cap while the
system is hot or under pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
