NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads ªHº, pull
over and stop the vehicle with the engine at idle,
when safe. Turn the air conditioner off and wait until
the pointer drops back into the normal range. After
appropriate action has been taken, if the pointer
remains on the ªHº, turn the engine off immediately,
and call 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 a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to Section 7, Maintenance, of
this manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
AUTOMATIC TRANSAXLE OVERHEATING
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transaxle oil may
become too hot. If this happens, the transmission over-
heat indicator light will come on and the vehicle will
slow slightly until the automatic transaxle cools down
enough to allow a return to the requested speed. If the
high speed is maintained, the overheating will reoccur as
before in a cyclic fashion.

WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the proper equipment.
If you have any doubt about your ability to perform
a service job, take your vehicle to a competent
mechanic.
MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure 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 5
minutes after a fully warmed engine is shut off. Do not
check oil level before starting the engine after it has sat
overnight. Checking engine oil level when the engine is
cold will give you an incorrect reading.
Engine Oil Dipstick
MAINTAINING YOUR VEHICLE 245
7

Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings. Maintain the oil level between the
range markings on the dipstick. The range markings will
consist of a crosshatch zone that says SAFE or a cross-
hatch zone that says MIN at the low end of the range and
MAX at the high end of the range. Adding one quart of
oil when the reading is at the low end of the indicated
range will result in the oil level at the full end of the
indicator range.
CAUTION!
Do not overfill the engine. Overfilling the engine as
indicated by the range markings, as described above,
on the engine oil dipstick will cause oil aeration,
which can lead to loss of oil pressure and an increase
in oil temperature. This could damage your engine.
Change Engine Oil
Road conditions and your kind of driving affects the
interval at which your oil should be changed. Check the
following list to decide if any apply to you.
²Day and night temperatures are below 32ÉF (0ÉC).
²Stop and Go driving.
²Extensive engine idling.
²Driving in dusty conditions.
²Short trips of less than 10 miles (16 km).
²More than 50% of your driving is at sustained high
speeds during hot weather, above 90ÉF (32ÉC).
²Trailer towing.
²Taxi, Police or delivery service (commercial service).
²Off-Road or desert operation.
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first, and follow schedule ªBÐAll
Enginesº of the9Maintenance Schedules9section of this
manual.
246 MAINTAINING YOUR VEHICLE

If none of these apply to you, then change your engine
oil at every interval shown on schedule ªAº in the
maintenance schedule section of this manual.
NOTE:
Under no circumstances should oil change
intervals exceed 6000 miles (10 000 km) or 6 months
whichever comes first.
Engine Oil Selection - Non ACEA Categories
For best performance and maxi-
mum protection under all types of
operating conditions, the manu-
facturer only recommends engine
oils that are API certified and
meet the requirements of
DaimlerChrysler Material Stan-
dard MS-6395. Use Mopar or an
equivalent oil meeting the specifi-
cation MS-6395. These Certified Oils exhibit the Ameri-
can Petroleum Institute (API) Engine Oil Certification
Symbol on the front of the oil container. This symbol
means that the oil has been tested, certified and licensed
by the American Petroleum Institute (API) to meet the oil
standards required by the manufacturers.
Engine Oil Selection - ACEA Categories
For countries that use the ACEA European Oil Categories
for Service Fill Oils, use engine oils that meet the require-
ments of ACEA A1/B1, A3/B4 or A3/B3.
Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low tempera-
ture starting and vehicle fuel economy. Your engine oil
filler cap also states the recommended engine oil vis-
cosity grade for your engine.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, use only those oils that are certified by
the American Petroleum Institute (API) to display the
symbol on the front of the container or the proper ACEA
category and show the recommended SAE viscosity
grade. Follow the maintenance schedule that describes
your driving type.

Materials Added To Engine Oils
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it's performance may be impaired by supplemental ad-
ditives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
present a problem to the environment. Contact your
dealer, service station, or governmental agency for advice
on how and where used oil can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All of this manufacturers engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Mopar Engine Oil Filters are high
quality oil filters and are recommended.
Engine Oil Requirements Ð Diesel Engines
Checking Oil Level
To assure 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 5
minutes after a fully warmed engine is shut off or before
starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level between the MIN and MAX markings on the
dipstick. Adding 1qt (1 liter) of oil when the reading is at
the MIN mark will result in a MAX reading on these
engines.
248 MAINTAINING YOUR VEHICLE

Selecting Engine Oil
Viscosity:Grade 5W-40 is recommended.
Oil Quality:Use only Synthetic Diesel engine oils con-
forming to the most current version of ACEA A3/B4 or
A3/B4/C3.
Drive Belt Ð Check Condition
At the mileage shown in the maintenance schedules,
check the drive belt for condition.
Inspect the drive belt for evidence of cuts, cracks, or
glazing and replace belt if any sign of damage which
could result in belt failure.
The belt is self-tensioning and will not need adjustment.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Refer to the Engine data Label located under the
hood for the proper type of spark plug for use in your
vehicle.
Ignition Wiring System
The ignition cables should be kept clean and properly
connected. Terminals should be fully seated. Cracked,
damaged, or faulty cables should be replaced.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.

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.
WARNING!
²Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer
to Section 3 of the Warranty Information book for
further warranty information.
²The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced repairman.
Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, or Refrigerants.
Power Steering Ð Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.
