SERVICING AND MAINTENANCE

All passenger vehicle tires must conform

to Federal safety requirements in

addition to these grades.

T

READWEAR

The Treadwear grade is a comparative

rating, based on the wear rate of the tire

when tested under controlled conditions

on a specified government test course.

For example, a tire graded 150 would

wear one and one-half times as well

on the government course as a tire

graded 100. The relative performance

of tires depends upon the actual

conditions of their use, however, and

may depart significantly from the norm

due to variations in driving habits,

service practices, and differences in

road characteristics and climate.

T

RACTION

G

RADES

The Traction grades, from highest to

lowest, are AA, A, B, and C. These grades

represent the tire's ability to stop on

wet pavement, as measured under

controlled conditions on specified

government test surfaces of asphalt

and concrete. A tire marked C may

have poor traction performance.

T

EMPERATURE

G

RADES

The Temperature grades are A (the

highest), B, and C, representing the tire's

resistance to the generation of heat and

its ability to dissipate heat, when tested

under controlled conditions on a

specified indoor laboratory test wheel.

Sustained high temperature can cause

the material of the tire to degenerate

and reduce tire life, and excessive

temperature can lead to sudden tire

failure. The grade C corresponds to a level

of performance, which all passenger

vehicle tires must meet under the Federal

Motor Vehicle Safety Standard No. 109.

Grades B and A represent higher levels of

performance on the laboratory test wheel,

than the minimum required by law.

WARNING!

The traction grade assigned to this tire is

based on straight-ahead braking traction

tests, and does not include acceleration,

cornering, hydroplaning, or peak traction

characteristics.

WARNING!

The temperature grade for this tire is

established for a tire that is properly inflated

and not overloaded. Excessive speed,

under-inflation, or excessive loading, either

separately or in combination, can cause heat

buildup and possible tire failure.

STORING THE VEHICLE

If you are storing your vehicle for more than

three weeks, we recommend that you take the

following steps to minimize the drain on your

vehicle's battery:



Disconnect the negative cable from battery.



Any time 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 setting. This will ensure adequate

system lubrication to minimize the possibility

of compressor damage when the system is

started again.

GENTS

Vehicle body care requirements vary according

to geographic locations and usage. Chemicals

that make roads passable in snow and ice and

those that are sprayed on trees and road

surfaces during other seasons are highly

corrosive to the metal in your vehicle. Outside

parking, which exposes your vehicle to airborne

contaminants, road surfaces on which the

vehicle is operated, extreme hot or cold weather

and other extreme conditions will have an

adverse effect on paint, metal trim, and

underbody protection.
The following maintenance recommendations

will enable you to obtain maximum benefit from

the corrosion resistance built into your vehicle.

What Causes Corrosion?

Corrosion is the result of deterioration or

removal of paint and protective coatings from

your vehicle.
The most common causes are:



Road salt, dirt and moisture accumulation.



Stone and gravel impact.



Insects, tree sap and tar.



Salt in the air near seacoast localities.



Atmospheric fallout/industrial pollutants.

Cleaning Headlights

Your vehicle is equipped with plastic headlights

and fog lights that are lighter and less

susceptible to stone breakage than glass

headlights.
Plastic is not as scratch resistant as glass and

therefore different lens cleaning procedures

must be followed.
To minimize the possibility of scratching the

lenses and reducing light output, avoid wiping

with a dry cloth. To remove road dirt, wash with

a mild soap solution followed by rinsing.
Do not use abrasive cleaning components,

solvents, steel wool or other aggressive

material to clean the lenses.

Washing



Wash your vehicle regularly. Always wash

your vehicle in the shade using Mopar Car

Wash, or a mild car wash soap, and rinse the

panels completely with water.



If insects, tar, or other similar deposits have

accumulated on your vehicle, use Mopar

Super Kleen Bug and Tar Remover to

remove.



Use a high quality cleaner wax, such as

Mopar Cleaner Wax to remove road film,

stains and to protect your paint finish.

Use precautions to not scratch the paint.



Avoid using abrasive compounds and power

buffing that may diminish the gloss or thin

out the paint finish.

Special Care



If you drive on salted or dusty roads or if you

drive near the ocean, hose off the undercar

-

riage at least once a month.



It is important that the drain holes in the

lower edges of the doors, rocker panels, and

trunk be kept clear and open.



If you detect any stone chips or scratches in

the paint, touch them up immediately.



If your vehicle is damaged due to a collision

or similar cause that destroys the paint and

protective coating, have your vehicle repaired

as soon as possible.



If you carry special cargo such as chemicals,

fertilizers, de-icer salt, etc., be sure that such

materials are well packaged and sealed.



If a lot of driving is done on gravel roads,

consider mud or stone shields behind each

wheel.



BRAKE SYSTEM

If power assist is lost for any reason (for

example, repeated brake applications with

the engine off), the brakes will still function.

However, you will experience a substantial

increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses

normal braking capability, the remaining system

will still function with some loss of overall braking

effectiveness. This will be evident by increased

pedal travel during application, greater pedal

force required to slow or stop, and activation of

WHEEL AND TIRE TORQUE SPECIFICATIONS

Proper lug nut/bolt torque is very important to

ensure that the wheel is properly mounted to the

vehicle. Any time a wheel has been removed and

reinstalled on the vehicle, the lug nuts/bolts

should be torqued using a properly calibrated

torque wrench using a six sided (hex) deep wall

socket.

**Use only authorized dealer recommended

lug nuts/bolts and clean or remove any dirt or

oil before tightening.

Inspect the wheel mounting surface prior to

mounting the tire and remove any corrosion or

loose particles.

NOTE:

Dual wheels are flat mounted, center piloted.

The lug nuts are a two-piece assembly. When

the tires are being rotated or replaced, clean

these lug nuts and add two drops of oil at the

interface between the hex and the washer.

Ensure that the socket is fully engaged on the

lug nut/bolt (do not insert it half way).

Oil Interface Location

Do not oil wheel studs. For chrome wheels, do

not substitute with chrome plated wheel nuts.

Wheel Mounting Surface

Retighten the wheel nuts in the same sequence

to the torques listed in the table. Go through the

sequence a second time to verify that specific

torque has been achieved. Retighten to

8/10 Lug Nuts/Bolts Torque Patterns

It is recommended that wheel stud nuts be kept

torqued to specifications at all times. Torque

wheel stud nuts to specifications at each

lubrication interval.
All wheel nuts should be tightened occasionally

to eliminate the possibility of wheel studs being

sheared or the bolt holes in the wheels becoming

elongated. This is especially important during the

first few hundred miles/kilometers of operation

to allow the wheel nuts to become properly set.

All wheel nuts should first be firmly seated

against the wheel. The wheel nuts should then be

tightened to recommended torque. Tighten the

wheel nuts to final torque in increments.

Progress around the bolt circle, tightening the

wheel nut opposite to the wheel nut just

previously tightened until final torque is

achieved.

FUEL REQUIREMENTS — GASOLINE ENGINE

While operating on gasoline with the required

octane number, hearing a light knocking sound

from the engine is not a cause for concern.

However, if the engine is heard making a heavy

knocking sound, see a dealer immediately. Use

of gasoline with a lower than recommended

octane number can cause engine failure and

may void or not be covered by the New Vehicle

Limited Warranty.
Poor quality gasoline can cause problems such as

hard starting, stalling, and hesitations. If you

experience these symptoms, try another brand of

gasoline before considering service for the vehicle.

FUEL REQUIREMENTS – DIESEL ENGINE

Use good quality diesel fuel from a reputable

supplier in your vehicle. Federal law requires

that you must fuel this vehicle with Ultra Low

Sulfur Highway Diesel fuel (15 ppm Sulfur

maximum) and prohibits the use of Low Sulfur

Highway Diesel fuel (500 ppm Sulfur maximum)

to avoid damage to the emissions control

system.
For most year-round service, Number 2 diesel

fuel meeting ASTM (formerly known as the

American Society for Testing and Materials)

specification D-975 Grade S15 will provide

good performance. If the vehicle is exposed

to extreme cold (below 20°F or -7°C), or is

required to operate at colder-than-normal

conditions for prolonged periods, use climatized

Number 2 diesel fuel or dilute the Number 2

diesel fuel with 50% Number 1 diesel fuel. This

will provide better protection from fuel gelling or

wax-plugging of the fuel filters.

Diesel fuel is seldom completely free of water.

To prevent fuel system trouble, drain the

accumulated water from the fuel/water

separator using the fuel/water separator drain

provided on both fuel filters. If you buy good

quality fuel and follow the cold weather advice

above, fuel conditioners should not be required

in your vehicle. If available in your area, a high

cetane “premium” diesel fuel may offer improved

cold-starting and warm-up performance.

that you understand and comply with these

requirements. Failure to comply with Oil Change

requirements for vehicles operating on

biodiesel blends up to B20 will result in

premature engine wear. Such wear is not

covered by the New Vehicle Limited Warranty.
Biodiesel is a fuel produced from renewable

resources typically derived from animal fat,

rapeseed oil (Rapeseed Methyl Ester (RME)

base), or soybean oil (Soy Methyl Ester (SME or

SOME) base). Biodiesel fuel has inherent

limitations which require that you understand

and adhere to the following requirements if you

use blends of biodiesel greater then 5% but not

greater than 20% (B6-B20). There are no

unique restrictions for the use of B5. Use of

blends greater than 20% is not approved. Use of

blends greater than 20% can result in engine

damage. Such damage is not covered by the

New Vehicle Limited Warranty.

Fuel Quality — Must Comply With ASTM

Standards

The quality of biodiesel fuel may vary widely.

Only fuel produced by a BQ9000 supplier to the

following specifications may be blended to

meet biodiesel blend (B6–B20) fuel meeting

ASTM specification D-7467:



Petrodiesel fuel meeting ASTM specification

D-975 and biodiesel fuel (B100) meeting

ASTM specification D-6751.

Fuel Oxidation Stability — Must Use Fuel

Within Six Months Of Manufacture

Biodiesel fuel has poor oxidation stability which

can result in long term storage problems. Fuel

produced to approved ASTM standards, if

stored properly, provides for protection against

fuel oxidation for up to six months.

TECHNICAL SPECIFICATIONS

Fuel Water Separation — Must Use Mopar/

Cummins Approved Fuel Filter Elements

You must use Mopar/Cummins approved fuel

filter elements in both your engine mounted

filter and frame mounted filter.
Biodiesel fuel has a natural affinity to water and

water accelerates microbial growth. Your

Mopar/Cummins filtration system is designed

to provide adequate fuel water separation

capabilities.

Bio-Diesel Fuel Properties — Low Ambient

Temperatures

Biodiesel fuel may gel or solidify at low ambient

temperatures, which may pose problems for

both storage and operation. Precautions can be

necessary at low ambient temperatures, such

as storing the fuel in a heated building or a

heated storage tank, or using cold temperature

additives.

Fuel In Oil Dilution — Must Adhere To

Required Oil Change Interval

Fuel dilution of lubricating oil has been observed

with the use of biodiesel fuel. Fuel in oil must not

exceed 5%. To ensure this limit is met your oil

change interval must be maintained to the

following schedule:

In ambient temperatures above 0°F (-18°C), we recommend you use 10W-30 engine oil such

as Mopar, Shell Rotella and Shell Rimula that meets FCA Material Standard MS-10902 and the

API CK-4 engine oil category is required. Products meeting Cummins CES 20081 may also be

used. The identification of these engine oils is typically located on the back of the oil container.
In ambient temperatures below 0°F (-18°C), we recommend you use 5W-40 synthetic engine

oil such as Mopar, Shell Rotella and Shell Rimula that meets FCA Material Standard MS-10902

and the API CK-4 engine oil category is required.

Engine Oil Filter

We recommend you use a Mopar Engine Oil Filter. If a Mopar Engine Oil Filter is unavailable

only use filters that meet or exceed SAE/USCAR-36 Filter Performance Requirements.

Fuel Filters

We recommend you use Mopar Fuel Filter. Must meet 3 micron rating (engine mounted filter).

Must meet 5 micron rating (chassis mounted filter). Using a fuel filter that does not meet the

manufacturer’s filtration and water separating requirements can severely impact fuel system

life and reliability.

Crankcase Ventilation Filter

We recommend you use Mopar CCV Filter.
