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.

Tri-Fold Soft Tonneau Cover Care — If

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.

Fascia/Bumper Care

The customer is responsible to clean and maintain

the chrome components of the vehicle. Washing

away road debris and salt using an automotive

soap. Fascia/bumpers should be cleaned regularly

using mild (neutral Ph) soap and water to maintain

their luster and to prevent corrosion.
Your fascia/bumpers are susceptible to

deterioration caused by salt, sodium chloride,

magnesium chloride, calcium chloride, etc., and

other road chemicals used to melt ice or control

dust on dirt roads. Do not use harsh chemicals or

a stiff brush. They can stain or damage the

protective coating that helps keep them from

corroding and tarnishing.

CAUTION!



Do not use abrasive or strong cleaning mate

-

rials such as steel wool or scouring powder

that will scratch metal and painted surfaces.



Use of power washers exceeding 1,200 psi

(8,274 kPa) can result in damage or removal

of paint and decals.

Special Care



If you drive on salted or dusty roads or if you

drive near the ocean, hose off the undercarriage

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 protec

-

tive 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.



Use Mopar® Touch Up Paint on scratches as

soon as possible. An authorized dealer has

touch up paint to match the color of your

vehicle.

Spray-On Bedliner – If Equipped

During ownership, the shine and luster of the

Spray-On Bedliner can fade from oxidation, road

dirt, heavy-duty hauling and hard water stains.

Weathering and UV exposure will lead to fading,

dulling, and loss of gloss over time.
To help maintain the appearance of your Spray-On

Bedliner, the manufacturer recommends you

periodically rinse all loose dirt from your truck bed

and clean your truck at least twice per year using

the Mopar® Spray-On Bedliner Conditioner

available at a local authorized dealer.

To Help Maintain The Appearance Of Your

Spray-On Bedliner, Follow The Steps Below:
1. Rinse your truck bed out with water to remove

any loose dirt and debris.

2. Mix a mild soap or detergent with water with a

soft cloth or brush.

3. Rinse bedliner with water.
4. Once dry, apply a small amount of Mopar®

Spray-On Bedliner Conditioner to a moist towel

or sponge and wipe over the entire surface of

the truck bedliner.

Spray-On Bedliners are chemically-resistant to

many different types of chemicals (including

gasoline, oil, hydraulic fluids) for short periods of

time. If a spill occurs on your Spray-On Bedliner,

rinse the truck out as soon as possible to avoid

permanent damage.

CAUTION!

Do not use scouring pads, steel wool, a bristle

brush, metal polishes, or oven cleaner. These

products may damage the fascia/bumper’s

protective finish. Such damage is not covered by

the New Vehicle Limited Warranty. Only car wash

soap, Mopar® Chrome Cleaner, or equivalent is

recommended.
Avoid products or automatic car washes that use

acidic solutions, strong alkaline additives, or

harsh brushes. Many aftermarket cleaners and

automatic car washes may damage the fascia/

bumper’s protective finish. Such damage is not

covered by the New Vehicle Limited Warranty.

Only car wash soap, Mopar® Chrome Cleaner, or

equivalent is recommended.

WARNING!

Do not use silicon-based protection products to

clean your bedliner. Silicon-based products can

become slippery and may result in personal

injury.

SERVICING AND MAINTENANCE

Repairing The Spray-On Bedliner
While extremely tough, it is possible to damage a

Spray-On Bedliner. One common condition is when

loading a heavy pallet and dragging that pallet

across the floor of the bed. If a nail or sharp point

is exposed under the weight of the pallet a scratch

or tear is possible. While not covered by your new

vehicle warranty, a cosmetic fix to cover the metal

exposed by the scratch is required. To repair a tear

or gouge, follow the directions provided in the

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 the

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 No. 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.

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.

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.

Biodiesel 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:

Fuel Selection

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

specification D-975 Grade S15 will provide good performance.
If climatized or diesel Number 1 ULSD fuel is not available, and you are

operating below (20°F/-6°C), in sustained arctic conditions, Mopar®

Premium Diesel Fuel Treatment (or equivalent) is recommended to avoid

gelling.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel

meeting ASTM specification D-975. Pickup models configured with optional
