²National Lubricating Grease Institute (NLGI)
API SERVICE GRADE CERTIFIED
Use an engine oil that is API Certified (GF-3).
Mopartprovides engine oils, meeting Material Stan-
dard MS-6395, that meet or exceed this requirement.
SAE VISCOSITY
An SAE viscosity grade is used to specify the vis-
cosity of engine oil. Use only engine oils with multi-
ple viscosities such as 5W-30 or 10W-30. These are
specified with a dual SAE viscosity grade which indi-
cates the cold-to-hot temperature viscosity range.
Select an engine oil that is best suited to your par-
ticular temperature range and variation (Fig. 2).
ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for
gasoline engines. The designation of ENERGY CON-
SERVING is located on the label of an engine oil con-
tainer.
CONTAINER IDENTIFICATION
Standard engine oil identification notations have
been adopted to aid in the proper selection of engine
oil. The identifying notations are located on the front
label of engine oil plastic bottles and the top of
engine oil cans (Fig. 3).
This symbol means that the oil has been certified
by the American Petroleum Institute (API). Diamler-
Chrysler only recommends API Certified (GF-3)
engine oils that meet the requirements of Material
Standard MS-6395. Use Mopartor an equivalent oil
meeting the specification MS-6395.
SYNTHETIC ENGINE OILS
There are a number of engine oils being promoted
as either synthetic or semi-synthetic. If you chose touse such a product, useonlythose oils that meet the
American Petroleum Institute (API) and SAE viscos-
ity standard. Follow the service schedule that
describes your driving type.
ENGINE OIL ADDITIVES/SUPPLEMENTS
The manufacturerdoes not recommendthe addi-
tion of any engine oil additives/supplements to the
specified engine oil. Engine oil additives/supplements
should not be used to enhance engine oil perfor-
mance. Engine oil additives/supplements should not
be used to extend engine oil change intervals. No
additive is known to be safe for engine durability and
can degrade emission components. Additives can con-
tain undesirable materials that harm the long term
durability of engines by:
²Doubling the level of Phosphorus in the engine
oil. The ILSAC (International Lubricant Standard
Approval Committee) GF-2 and GF-3 standards
require that engine oil contain no more than 0.10%
Phosphorus to protect the vehicles emissions perfor-
mance. Addition of engine oil additives/supplements
can poison, from the added sulfur and phosphorus,
catalysts and hinder efforts to guarantee emissions
performance to 80,000 miles.
²Altering the viscosity characteristics of the
engine oil so that it no longer meets the require-
ments of the specified viscosity grade.
²Creating potential for an undesirable additive
compatibility interaction in the engine crankcase.
Generally it is not desirable to mix additive packages
from different suppliers in the crankcase; there have
been reports of low temperature engine failures
caused by additive package incompatibility with such
mixtures.
GEAR LUBRICANTS
SAE ratings also apply to multigrade gear lubri-
cants. In addition, API classification defines the
lubricants usage. Such as API GL-5 and SAE 75W-
90.

LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 4) on the label. At the bottom of the
NLGI symbol is the usage and quality identification
letters. Wheel bearing lubricant is identified by the
letter ªGº. Chassis lubricant is identified by the letter
ªLº. The letter following the usage letter indicates
the quality of the lubricant. The following symbols
indicate the highest quality.
SPECIALIZED LUBRICANTS AND OILS
Some maintenance or repair procedures may
require the use of specialized lubricants or oils. Con-
sult the appropriate sections in this manual for the
correct application of these lubricants.
DESCRIPTION - ENGINE COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL
BASE COOLANT AND IS HARMFUL IF SWAL-
LOWED OR INHALED. IF SWALLOWED, DRINK
TWO GLASSES OF WATER AND INDUCE VOMIT-
ING. IF INHALED, MOVE TO FRESH AIR AREA.
SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT
STORE IN OPEN OR UNMARKED CONTAINERS.
WASH SKIN AND CLOTHING THOROUGHLY AFTER
COMING IN CONTACT WITH ETHYLENE GLYCOL.
KEEP OUT OF REACH OF CHILDREN. DISPOSE OF
GLYCOL BASE COOLANT PROPERLY, CONTACT
YOUR DEALER OR GOVERNMENT AGENCY FOR
LOCATION OF COLLECTION CENTER IN YOUR
AREA. DO NOT OPEN A COOLING SYSTEM WHEN
THE ENGINE IS AT OPERATING TEMPERATURE OR
HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN
ENGINE COMPARTMENT RELATED SERVICE IS
PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene Glycol based coolants
is not recommended, as they provide less freeze
protection and less boiling protection.The cooling system is designed around the coolant.
The coolant must accept heat from engine metal, in
the cylinder head area near the exhaust valves and
engine block. Then coolant carries the heat to the
radiator where the tube/fin radiator can transfer the
heat to the air.
The use of aluminum cylinder blocks, cylinder
heads, and water pumps requires special corrosion
protection. MopartAntifreeze/Coolant, 5
Year/100,000 Mile Formula (MS-9769), or the equiva-
lent ethylene glycol base coolant with hybrid organic
corrosion inhibitors (called HOAT, for Hybrid Organic
Additive Technology) is recommended. This coolant
offers the best engine cooling without corrosion when
mixed with 50% Ethylene Glycol and 50% distilled
water to obtain a freeze point of -37ÉC (-35ÉF). If it
loses color or becomes contaminated, drain, flush,
and replace with fresh properly mixed coolant solu-
tion.
The green coolantMUST NOT BE MIXEDwith
the orange or magenta coolants. When replacing cool-
ant the complete system flush must be performed
before using the replacement coolant.
CAUTION: MoparTAntifreeze/Coolant, 5
Year/100,000 Mile Formula (MS-9769) may not be
mixed with any other type of antifreeze. Doing so
will reduce the corrosion protection and may result
in premature water pump seal failure. If non-HOAT
coolant is introduced into the cooling system in an
emergency, it should be replaced with the specified
coolant as soon as possible.
DESCRIPTION - FLEXIBLE FUEL ENGINE OIL
The information in this section is for Flexible Fuel
Vehicles (FFV) only. These vehicles can be identified
by the unique Fuel Filler Door Label that states
Ethanol (E-85) or Unleaded Gasoline Only. This sec-
tion only covers those subjects that are unique to
these vehicles. Please refer to the other sections of
this manual for information on features that are
common between Flexible Fuel and gasoline only
powered vehicles.
ETHANOL FUEL (E-85)
E-85 is a mixture of approximately 85% fuel etha-
nol and 15% unleaded gasoline.
WARNING: Ethanol vapors are extremely flammable
and could cause serious personal injury. Never
have any smoking materials lit in or near the vehi-
cle when removing the fuel filler tube cap (gas cap)
or filling the tank. Do not use E-85 as a cleaning
agent and never use it near an open flame.

FLUID TYPES (Continued)

FUEL REQUIREMENTS
The vehicle will operate on both unleaded gasoline
with an octane rating of 87, or E-85 fuel, or any mix-
ture of these two.
For best results, a refueling pattern that alternates
between E-85 and unleaded gasoline should be
avoided. When you do switch fuels, it is recom-
mended that
²you do not switch when the fuel gauge indicates
less than 1/4 full
²you do not add less than 5 gallons when refuel-
ing
²you operate the vehicle immediately after refuel-
ing for a period of at least 5 minutes
Observing these precautions will avoid possible
hard starting and/or significant deterioration in
driveability during warm up.
FFV STARTING
The characteristics of E-85 fuel make it unsuitable
for use when ambient temperatures fall below 0ÉF. In
the range of 0ÉF to 32ÉF, you may experience an
increase in the time it takes for your engine to start,
and a deterioration in driveability (sags and/or hesi-
tations) until the engine is fully warmed up.
Engine Operating on E-85 Fuel
If vehicle operates on E-85 fuel either full or part-
time, use only MopartFlexible Fuel 5W-30 engine oil
or an equivalent that meets DaimlerChrysler Stan-
dard MS-9214. Equivalent commercial Flexible Fuel
engine oils may be labeled as Multi-Fuel, Variable
Fuel, Flexible Fuel, etc. These engine oils may be
satisfactory if they meet the DaimlerChrysler Stan-
dard.
SAE 5W-30 engine oil is preferred for use in Flex-
ible Fuel engines.
CAUTION: If Flexible Fuel engine oil is not used
when using E-85 fuel, engine wear or damage may
result.
CRUISING RANGE
Because E-85 fuel contains less energy per gallon
than gasoline, you will experience an increase in fuel
consumption. You can expect your MPG and your
driving range to decrease by about 30% compared to
gasoline operation.
DESCRIPTION - AUTOMATIC/MANUAL
TRANSAXLE FLUID
NOTE: Refer to the maintenance schedules for the
recommended maintenance (fluid/filter change)
intervals for these transaxles.NOTE: All transaxles have a common transmission
and differential sump. Filling the transaxle accom-
modates the differential as well.
TRANSMISSION FLUID
MopartATF+4 (Automatic Transmission Fluid) is
required in the 41TE automatic and T850 manual
transaxles. Substitute fluids can induce transmission
problems and/or failure.
MopartATF+4 (Automatic Transmission Fluid)
when new is red in color. The ATF is dyed red so it
can be identified from other fluids used in the vehicle
such as engine oil or antifreeze. The red color is not
permanent and is not an indicator of fluid condition.
As the vehicle is driven, the ATF will begin to look
darker in color and may eventually become brown.
This is normal.ATF+4 also has a unique odor that
may change with age. Consequently,odor and color
cannot be used to indicate the fluid condition
or the need for a fluid change.
FLUID ADDITIVES
DaimlerChrysler strongly recommends against the
addition of any fluids to the transmission, other than
those automatic transmission fluids listed above.
Exceptions to this policy are the use of special dyes
to aid in detecting fluid leaks.
Various ªspecialº additives and supplements exist
that claim to improve shift feel and/or quality. These
additives and others also claim to improve converter
clutch operation and inhibit overheating, oxidation,
varnish, and sludge. These claims have not been sup-
ported to the satisfaction of DaimlerChrysler and
these additivesmust not be used.The use of trans-
mission ªsealersº should also be avoided, since they
may adversely affect the integrity of transmission
seals.
DESCRIPTION - FUEL REQUIREMENTS
Your engine is designed to meet all emissions reg-
ulations and provide excellent fuel economy and per-
formance when using high quality unleaded gasoline
having an octane rating of 87. The use of premium
gasoline is not recommended. The use of premium
gasoline will provide no benefit over high quality reg-
ular gasoline, and in some circumstances may result
in poorer performance.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued heavy
spark knock at high speeds can cause damage and
immediate service is required. Engine damage result-
ing from operation with a heavy spark knock may
not be covered by the new vehicle warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling and hesitations. If you experi-

DIESEL ENGINE
WARNING: DO NOT USE ALCOHOL OR GASOLINE
AS A FUEL BLENDING AGENT. THEY CAN BE
UNSTABLE UNDER CERTAIN CONDITIONS AND
HAZARDOUS OR EXPLOSIVE WHEN MIXED WITH
DIESEL FUEL.
Use good quality diesel fuel from a reputable sup-
plier. For most year-round service, number 2 diesel
fuel meeting DIN EN 590 (Class0-4)will provide
good performance. If the vehicle is exposed to
extreme cold (below -18ÉC/0ÉF) or is required to oper-
ate at colder than normal conditions for prolonged
periods, use climatize No. 2 diesel fuel or dilute the
No. 2 diesel fuel with 50% No. 1 diesel fuel as long as
it meets ASTM D 975: 1D and 2D and the quality of
lubrication behavior is in accordance with DIN EN
590. This will provide better protection from fuel gel-
ling or wax plugging of the fuel filters.
Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, including fuel line freez-
ing in winter, drain the accumulated water from the
fuel/water separator using the fuel/water separator
drain provided. If you buy good quality fuel and fol-
low the cold weather advice above, fuel conditioners
should not be required in your vehicle. If available in
your area, a high cetane ªpremiumº diesel fuel may
offer improved cold starting and warm up perfor-
mance.
DESCRIPTION - ENGINE OIL - DIESEL
ENGINES
Use only Diesel Engine Oil meeting standardMIL-

CAUTION: Low viscosity oils must have the proper
API quality or the CCMC G5 designation.
To assure of properly formulated engine oils, it is
recommended that SAE Grade 10W-40 engine oils
that meet Chrysler material standard MS-6395, be
used in accordance to ACEA B3, B4 specification.
European Grade 10W-40 oils are also acceptable.
Oils of the SAE 5W-40 grade number are preferred
when minimum temperatures consistently fall below
-15ÉC.

MAINTENANCE SCHEDULES (Continued)

If the vacuum supply is 12 inches Hg (40.5 kPa) or
more, the power brake booster is defective and must
be replaced. If the vacuum supply is below 12 inches
Hg, continue on with this BASIC TEST.
(6) Shut off the engine.
(7) Connect the vacuum gauge to the vacuum ref-
erence port on the engine intake manifold.
(8) Start the engine and observe the vacuum
gauge.
If the vacuum is still low, check the engine tune
and repair as necessary. If the vacuum is above 12
inches Hg, the hose or check valve to the booster has
a restriction or leak.
Once an adequate vacuum supply is obtained,
repeat the BASIC TEST.
VACUUM LEAK TEST
(1) Disconnect the vacuum hose on the vacuum
check valve, then place a vacuum gauge in line
between the vacuum hose and the valve.
(2) Start the engine.
(3) Allow the engine to warm up to normal operat-
ing temperature and engine idle.
(4) Using vacuum line pliers, close off the vacuum
supply hose near the booster, but before the vacuum
gauge, then observe the vacuum gauge.
If the vacuum drop exceeds 1.0 inch Hg (3.3 kPa)
in one minute, repeat the above steps to confirm the
reading. The vacuum loss should be less than 1.0
inch Hg in one minute time span. If the loss is more
than 1.0 inch Hg, replace the power brake booster. If
it is not, continue on with this test.
(5) Remove the pliers from the hose temporarily.
(6) Apply light effort (approximately 15 lbs. of
force) to the brake pedal and hold the pedal steady.
Do not move the pedal once the pressure is applied
or the test results may vary.
(7) Have an assistant reattach the vacuum line
pliers to the vacuum supply hose.
(8) Allow 5 seconds for stabilization, then observe
the vacuum gauge.
If the vacuum drop exceeds 3.0 inches Hg (10 kPa)
in 15 seconds, repeat the above steps to confirm the
reading. The vacuum loss should be less than 3.0
inches Hg in 15 seconds time span. If the loss is
more than 3.0 inches Hg, replace the power brake
booster. If it is not, the booster is not defective.
(9) Remove the pliers and vacuum gauge.
REMOVAL
REMOVAL - LHD
CAUTION: Reserve vacuum in power brake booster
must be pumped down (removed) before removing
master cylinder from booster. This is necessary toprevent booster from sucking in any contamination
as master cylinder is removed. This can be done
simply by pumping the brake pedal, with the vehi-
cle's engine not running, until a firm feeling brake
pedal is achieved.
(1) With engine not running, pump the brake
pedal until a firm pedal is achieved (4-5 strokes).
(2) Remove negative battery cable terminal from
battery.
(3) Remove positive battery cable terminal from
battery.
(4) Remove battery thermal guard shield.
(5) Remove battery clamp, nut and battery from

The ABS warning lamp will also be on for up to 5
seconds after the ignition is turned on. When the
vehicle is first driven off, a humming may be heard
or felt by the driver at approximately 20±40 kph
(12±25 mph). All of these conditions are a normal
function of ABS as the system is performing a diag-
nosis check.
PREMATURE ABS CYCLING
Symptoms of premature ABS cycling include: click-
ing sounds from the solenoid valves; pump/motor
running; and pulsations in the brake pedal. Prema-
ture ABS cycling can occur at any braking rate of the
vehicle and on any type of road surface. Neither the
red BRAKE warning lamp, nor the amber ABS warn-
ing lamp, illuminate and no fault codes are stored in
the CAB.
Premature ABS cycling is a condition that needs to
be correctly assessed when diagnosing problems with
the antilock brake system. It may be necessary to use
a DRB scan tool to detect and verify premature ABS
cycling.
Check the following common causes when diagnos-
ing premature ABS cycling: damaged tone wheels;
incorrect tone wheels; damaged steering knuckle
wheel speed sensor mounting bosses; loose wheel
speed sensor mounting bolts; excessive tone wheel
runout; or an excessively large tone wheel-to-wheel
speed sensor air gap. Give special attention to these
components when diagnosing a vehicle exhibiting
premature ABS cycling.
After diagnosing the defective component, repair or
replace it as required. When the component repair or
replacement is completed, test drive the vehicle to
verify that premature ABS cycling has been cor-
rected.
OPERATION - ELECTRONIC VARIABLE BRAKE
PROPORTIONING
Upon entry into EVBP the inlet valve for the rear
brake circuit is switched on so that the fluid supply
from the master cylinder is shut off. In order to
decrease the rear brake pressure, the outlet valve for
the rear brake circuit is pulsed. This allows fluid to
enter the low pressure accumulator (LPA) in the
hydraulic control unit (HCU) resulting in a drop in
fluid pressure to the rear brakes. In order to increase
the rear brake pressure, the outlet valve is switched
off and the inlet valve is pulsed. This increases the
pressure to the rear brakes. This back-and-forth pro-
cess will continue until the required slip difference is
obtained. At the end of EVBP braking (brakes
released) the fluid in the LPA drains back to themaster cylinder by switching on the outlet valve and
draining through the inlet valve check valve. At the
same time the inlet valve is switched on in case of
another brake application.
The EVBP will remain functional during many
ABS fault modes. If both the red BRAKE and amber
ABS warning indicators are illuminated, the EVBP
may not be functioning.
OPERATION - TRACTION CONTROL SYSTEM
The traction control module monitors wheel speed.
During acceleration, if the module detects front
(drive) wheel slip and the brakes are not applied, the
module enters traction control mode. Traction control
operation proceeds in the following order:
(1) Close the normally open isolation valves.
(2) Start the pump/motor and supply volume and
pressure to the front (drive) hydraulic circuit. (The
pump/motor runs continuously during traction con-
trol operation.)
(3) Open and close the build and decay valves to
maintain minimum wheel slip and maximum trac-
tion.
The cycling of the build and decay valves during
traction control is similar to that during antilock
braking, except the valves work to control wheel spin
by applying the brakes, whereas the ABS function is
to control wheel skid by releasing the brakes.
If the brakes are applied at anytime during a trac-
tion control cycle, the brake lamp switch triggers the
controller to switch off traction control.
HYDRAULIC SHUTTLE VALVES
Two pressure relief hydraulic shuttle valves allow
pressure and volume to return to the master cylinder
reservoir when not consumed by the build and decay
valves. These valves are necessary because the
pump/motor supplies more volume than the system
requires.
TRACTION CONTROL LAMP
The traction control system is enabled at each igni-
tion cycle. It may be turned off by depressing the
Traction Control Off switch button when the ignition
is in the ON position. The traction control function
lamp (TRAC OFF) illuminates immediately upon
depressing the button.
The traction control function lamp illuminates dur-
ing a traction control cycle, displaying TRAC.
If the CAB calculates that the brake temperatures
are high, the traction control system becomes inoper-
ative until a time-out period has elapsed. During this
ªthermo-protection mode,º the traction control func-
tion lamp illuminates TRAC OFF; note that no trou-
ble code is registered.
