364 STARTING AND OPERATING
Refer to the “Maintenance Schedule” in Section 8 for the proper maintenance intervals. More frequent rotation is permissible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being performed.
NOTE: On Canadian vehicles only, if your vehicle is equipped with All-Season type tires on the front and ON/OFF Road type tires mounted on the rear, do not use a front-to-back rotation pattern. Instead, rotate your tires side-to-side at the recommended intervals.
Dual Rear Wheels
The tires used on dual wheel assemblies should be matched for wear to prevent overloading one tire in a set. To check if tires are even, lay a straight edge across all four tires. The straight edge should touch all the tires.
STARTING AND OPERATING 365
CAUTION!
3500 Dual Rear Tires have only one approved direc- tion of rotation. This is to accommodate the asym- metrical design (tread pattern) of the ON/OFF road tire and the use of Outline White Letter (OWL) tires. • When replacing a flat, the spare tire may have to be remounted on the rim, or installed at a different location, to maintain the correct placement of the tire on the wheel relative to the tire/wheel position on the truck. For example, if the spare is used to replace an outer rear tire it will have to be re- mounted on the rim so that the wheel is dished inward. That way the tread design of asymmetrical tires and the white writing of the OWL tires will maintain proper position.
366 STARTING AND OPERATING
TIRE PRESSURE MONITOR SYSTEM (TPMS) — IF EQUIPPED The Tire Pressure Monitoring System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold tire inflation placard pressure. The placard pressure is defined on the Tire and Loading Information label. The Tire and Loading Information label is located on the drivers side B-pillar. Vehicles equipped to be operated in either the “max load inflation pressure” condition described on the Tire and Loading Information label or the alternative “light load inflation pressure” condition described on the Supplemental Tire Pressure Information label, may also be equipped with a “Tire Light Load Inflation” switch to choose the appro- priate TPMS low pressure warning threshold levels based upon the vehicle load condition. The Supplemental Tire Pressure Information label is located on the rear face of the driver door. Operation of the “Tire Light Load Inflation” switch is described later in this manual section.
The tire pressure will vary with temperature by approxi- mately 1 psi (6.9 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure. This is defined as the tire pressure after a vehicle has not been driven for more than three hours, or driven less than 1 mile (1.6 km) after a three-hour period. For information on how to properly inflate the vehicle’s tires, refer to ”Tire Pressure” under “Tires – General Information” in this section. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure. The TPM System will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning threshold for any reason, including low tem- perature effects, or natural pressure loss through the tire.
The TPM System will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above recom- mended cold placard pressure. Once the low tire pressure warning has been illuminated, the tire pressure must be increased to the recommended cold placard pressure in order for the TPMS warning light to be turned off. The system will automatically update and the TPMS warning light will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) to receive this information.
STARTING AND OPERATING 367
As an example, assume your vehicle has a recommended cold tire inflation placard pressure (parked for more than 3 hours) of 35 psi (241 kPa). If the ambient temperature is 68°F (20°C) and the measured tire pressure is 30 psi (207 kPa), a temperature drop to 20°F (-7°C) will decrease the tire pressure to approximately 26 psi (179 kPa). This tire pressure is sufficiently low enough to turn ON the “Tire Pressure Monitoring Telltale Light.” Driving the vehicle may cause the tire pressure to rise to approxi- mately 30 psi (207 kPa), but the “Tire Pressure Monitor- ing Telltale Light” will still be ON. In this situation, the “Tire Pressure Monitoring Telltale Light” will turn OFF only after the tires have been inflated to the vehicle’s recommended cold tire placard pressure value.
368 STARTING AND OPERATING
CAUTION!
• The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. After-market wheels can cause sensor dam- age. Do not use aftermarket tire sealants or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result. • After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Moni- toring Sensor.
while adjusting your tire pressure.
NOTE: • The TPMS is not intended to replace normal tire care and maintenance, nor to provide warning of a tire failure or condition. • The TPMS should not be used as a tire pressure gauge • Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. • The TPMS is not a substitute for proper tire mainte- nance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the “Tire Pressure Monitoring Telltale Light.” • Seasonal temperature changes will affect tire pressure, and the TPM system will monitor the actual tire pressure in the tire.
Tire Pressure Monitor System (TPMS) Tire Light Load Inflation Switch Description – If Equipped
WARNING!
Never operate your vehicle with the TPMS and tire pressures set to the Light Load Inflation Pressure settings if carrying more than two occupants (150 lbs [68 kg] each) plus 200 pounds (91 kg) of cargo. The vehicle “Light Load Definition” is found in the Supplemental Tire Pressure Information Label which is located on the rear face of the driver door. Failure to do so may cause you to lose control resulting in an accident, causing serious or fatal injury.
The TPMS tire light load inflation switch will allow the driver to switch between the max load inflation pressure (cold) low pressure warning threshold and the light load inflation pressure (cold) low pressure warning threshold depending on the vehicle’s load condition. The Tire and Loading Information label defines the recommended front
STARTING AND OPERATING 369
and rear cold tire inflation pressures for the vehicle when operating in the Max Load condition. A Supplemental Tire Pressure Information label is also available defining Light Load tire inflation pressures when operating in the Light Load condition. When the tire light load inflation switch LED is ON, the TPMS is using the light load inflation pressure (cold) low inflation warning thresholds.
Tire Light Load Inflation Switch
370 STARTING AND OPERATING
Tire Light Load Inflation Switch Operation – If Equipped • This vehicle may have different recommended tire pressure values between the front and rear tires as shown in both the Tire Loading Information Label and the Supplemental Tire Pressure Information Label. It is also equipped to be driven with tire pressures appro- priate to either a Light Load condition or the vehicle Max Load condition. • The tire light load inflation switch will allow the driver to change between the max load inflation pressure (cold) low pressure warning threshold and the light load inflation pressure (cold) low pressure warning threshold depending on the vehicle’s load condition. Refer to the “Supplemental Tire Pressure Information” label for the vehicle’s Light Load inflation pressures and “Tire and Loading Information” label for the vehicle’s Max Load inflation pressures.
Example Supplemental Tire Pressure Label
To switch from the max load inflation pressure (cold) low pressure warning threshold to the light load inflation pressure (cold) low pressure warning threshold, begin by placing the ignition switch in the RUN position. Next, lower all four road tire pressures to the Light Load Inflation Pressure values as listed on the Supplemental
Tire Pressure Information label. The Supplemental Tire Pressure Information label is located on the rear face of the driver door. Use an accurate tire gauge to check the tire pressures when lowering all four tire pressures. After all four tire pressures have been lowered to the Light Load inflation pressures, press the tire light load inflation switch. If the tire light load inflation switch’s amber colored LED turns ON, the TPMS is using the light load inflation pressure (cold) low pressure warning thresh- olds. If the tire light load inflation switch amber colored LED flashes on and off for 10 seconds, after all four tire pressures have been lowered to the Light Load inflation pressures, the pressure in any one of the four tires may not be at the light load inflation pressure (cold) values as indicated for the Light Load condition as defined on the Supplemental Tire Pressure Information label located on
STARTING AND OPERATING 371
the rear face of the driver door. Using an accurate tire pressure gauge, re-check the tire pressures for the light load inflation pressure (cold) value.
WARNING!
It is the driver’s responsibility to change to the max load inflation pressure (cold) low pressure warning threshold condition when not driving in the light load condition as defined as two occupants (150 lbs [68 kg] each) plus 200 pounds (91 kg) of cargo. The vehicle “Light Load Definition” is found in the Supplemental Tire Pressure Information label lo- cated on the rear face of the driver door. Failure to do so may cause you to lose control resulting in an accident, causing serious or fatal injury.
To switch back to the max load inflation pressure (cold) low pressure warning threshold, press the tire light load inflation switch. It is not necessary to first fill the tires to
372 STARTING AND OPERATING
the max load inflation pressure (cold) values to switch the TPMS system to the max load inflation pressure (cold) low pressure warning threshold. If after pressing the tire light load inflation switch, and tire pressures are below the max load inflation pressure (cold) low pressure warning thresholds, the TPMS low pressure warning telltale light (located in the instrument cluster) will turn ON and a chime will sound. The tire pressures are now required to be inflated to the max load inflation pressure (cold) values described on the Tire and Loading Informa- tion label. The Tire and Loading Information label is located on the drivers side B-pillar. If the tire light load inflation switch LED turns OFF, the TPMS has been reset and the TPMS is using the max load inflation pressure (cold) low pressure warning thresholds. Tire Pressure Monitor System Components The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the Receiver Module. It is particularly important, for you to check the NOTE: tire pressure in all of your tires regularly and to maintain the proper pressure. The Tire Pressure Monitoring System (TPMS) consists of the following components: • Receiver Module • Four Wheel Sensors • Two Trigger Modules (mounted in the front wheel- • Tire Light Load Inflation Switch (located in the instru- • Tire Pressure Monitoring Telltale Light

wells)
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will illuminate in the instrument cluster, and an au- dible chime will be activated when one or more of the four active road tire pressures are low. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your vehicle and inflate each tire to the vehicle’s recommended cold placard pressure value. The system will automatically update and the “Tire Pressure Monitoring Telltale Light” will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) to receive this information. Check TPMS Warnings The “Tire Pressure Monitoring Telltale Light” (located in the instrument cluster) will flash on and off for 75 sec- onds and will remain on solid when a system fault is detected. The system fault will also sound a chime. If the
STARTING AND OPERATING 373
ignition key is cycled, this sequence will repeat, provid- ing the system fault still exists. A system fault can occur by any of the following scenarios: 1. Signal interference due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the TPM sensors. 2. Installing aftermarket window tinting that affects ra- dio wave signals. 3. Accumulation of snow or ice around the wheels or wheel housings. 4. Using tire chains on the vehicle. 5. Using wheels/tires not equipped with TPM sensors. 6. Loss of communication with the trigger modules or tire pressure monitoring sensors. NOTE: Your vehicle is equipped with a non-matching full size spare wheel and tire assembly.
374 STARTING AND OPERATING
1. This spare tire does not have a tire pressure monitor- ing sensor. Therefore, the TPMS will not monitor the tire pressure in the spare tire. 2. If you install the full size spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, a chime will sound and the “TPM Telltale Light” will still turn ON due to the low tire. 3. However, after driving the vehicle for up to 20 min- utes above 15 mph (25 km/h), the “TPM Telltale Light” will flash on and off for 75 seconds and then remain on solid. 4. For each subsequent ignition key cycle, a chime will sound and the “TPM Telltale Light” will flash on and off for 75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the full size spare tire, the TPMS will update automatically and the “TPM Telltale Light” will turn OFF, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. General Information This device complies with part 15 of the FCC rules and RSS 210 of Industry Canada. Operation is subject to the following conditions: • This device may not cause harmful interference. • This device must accept any interference received, including interference that may cause undesired operation.

The 5.7L engine is designed to meet all emissions regulations and provide satisfac- tory fuel economy and performance when using high-quality unleaded gasoline hav- ing an octane range of 87 to 89. The manu- facturer recommends the use of 89 octane for optimum performance. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines. 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.
STARTING AND OPERATING 375
Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms, try another brand of “regular” gasoline be- fore considering service for the vehicle. Over 40 auto manufacturers worldwide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, performance and durability for your vehicle. We recommend the use of gasolines that meet the WWFC specifications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline” Reformulated gasolines contain oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality.
376 STARTING AND OPERATING
The manufacturer supports the use of reformulated gaso- lines. Properly-blended reformulated gasolines will pro- vide excellent performance and durability of engine and fuel system components. Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxy- genates such as 10% ethanol, MTBE, and ETBE. Oxygen- ates are required in some areas of the country during the Winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting and drivability problems and may damage critical fuel system components.Problems that result from using methanol/gasoline or E85 Ethanol blends are not the responsibility of the manufacturer. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Methanol. E-85 Usage In Non-Flex Fuel Vehicles Non-FFV vehicles are compatible with gasoline contain- ing 10% ethanol (E10). Gasoline with higher ethanol content may void the vehicle’s warranty. If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms: • operate in a lean mode • OBD II “Malfunction Indicator Light” on • poor engine performance • poor cold start and cold drivability • increased risk for fuel system component corrosionTo fix a Non-FFV vehicle inadvertently fueled once with E-85 perform the following: • drain the fuel tank (see your authorized dealer) • change the engine oil and oil filter • disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged exposure to E-85 fuel. MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase octane. Gasoline blended with MMT provides no performance advantage beyond gasoline of the same octane number without MMT. Gasoline blended with MMT reduces spark plug
STARTING AND OPERATING 377
life and reduces emission system performance in some vehicles. The manufacturer recommends that gasoline without MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump, therefore, you should ask your gasoline retailer whether or not the gasoline contains MMT. It is even more important to look for gasolines without MMT in Canada, because MMT can be used at levels higher than those allowed in the United States. MMT is prohibited in Federal and California reformulated gasoline. Materials Added To Fuel All gasolines sold in the United States are required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions and would result in unnecessary cost. There- fore, you should not have to add anything to the fuel.
378 STARTING AND OPERATING
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s performance: • The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance, damage the emission control system. • An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your authorized dealer for service assistance.
• When pulling a heavy load or driving a fully-loaded vehicle when the humidity is low and the temperature is high, use a premium unleaded fuel to help prevent spark knock. If spark knock persists, lighten the load, or engine piston damage may result. • The use of fuel additives which are now being sold as octane enhancers is not recommended. Many of these products contain high concentrations of methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is not the responsibility of the manufacturer.
NOTE: systems can result against you.
Intentional tampering with emissions control in civil penalties being assessed
Carbon Monoxide Warnings
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 mainte- nance. Have the exhaust system inspected every time
STARTING AND OPERATING 379
the vehicle is raised. Have any abnormal conditions repaired promptly. Until repaired, drive with all side windows fully open.
ADDING FUEL The fuel tank filler tube has a restricting door about 2 in (50 mm) inside the opening. If using a portable fuel container, it should have a flexible nozzle long enough to force open the restricting door.
CAUTION!
• Damage to the fuel system or emissions control system could result from using an improper fuel tank filler tube cap (gas cap). A poorly fitting cap could let impurities into the fuel system. Also, a poorly-fitted aftermarket cap can cause the MIL (Malfunction Indicator Light) to illuminate due to fuel vapors escaping from the system.
(Continued)
380 STARTING AND OPERATING
CAUTION! (Continued)
• A poorly fitting gas cap may cause the MIL to turn • To avoid fuel spillage and overfilling, do not “top
on.
off” the fuel tank after filling.
NOTE: Tighten the gas cap 1/4 turn until you hear one click. This is an indication that the cap is properly tightened. If the gas cap is not tightened properly, the Malfunction Indicator Light will come on, Be sure the gas cap is tightened every time the vehicle is refueled.
NOTE: When the fuel nozzle “clicks” or shuts off the fuel tank is full.
WARNING!
WARNING!
• Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank filled. • Never add fuel to the vehicle when the engine is running. This is in violation of most state and federal fire regulations and will cause the MIL to turn on.
A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be burned. Always place gas containers on the ground while filling.
Loose Fuel Filler Cap (Gas Cap) Message
If the vehicle’s diagnostic system determines that the fuel filler cap in loose, improperly installed or damaged, a GASCAP message will be displayed in the instrument cluster. Tighten the gas cap until a “clicking” sound is heard. This is an indication that the gas cap is properly tightened. Press the odometer reset button to turn the message off. If the problem persists, the message will appear the next time the vehicle is started. This might indicate a damaged cap. If the problem is detected twice in a row, the system will turn on the MIL. Resolving the problem will turn the MIL off.
VEHICLE LOADING
Certification Label As required by National Highway Traffic Safety Admin- istration regulations, your vehicle has a certification label affixed to the driver’s side door or pillar.
STARTING AND OPERATING 381
This label contains the month and year of manufacture, Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR) front and rear, and Vehicle Identification Number (VIN). A Month-Day-Hour (MDH) number is included on this label and indicates the Month, Day and Hour of manufacture. The bar code that appears on the bottom of the label is your Vehicle Identification Number (VIN). Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options and cargo. The label also specifies maximum capacities of front and rear axle systems (GAWR). Total load must be limited so GVWR and front and rear GAWR are not exceeded. Payload The payload of a vehicle is defined as the allowable load weight a truck can carry, including the weight of the driver, all passengers, options and cargo.
382 STARTING AND OPERATING
Gross Axle Weight Rating (GAWR) The GAWR is the maximum permissible load on the front and rear axles. The load must be distributed in the cargo area so that the GAWR of each axle is not exceeded. Each axle GAWR is determined by the components in the system with the lowest load carrying capacity (axle, springs, tires or wheels). Heavier axles or suspension components sometimes specified by purchasers for in- creased durability does not necessarily increase the vehi- cle’s GVWR. Tire Size The tire size on the Label represents the actual tire size on your vehicle. Replacement tires must be equal to the load capacity of this tire size. Rim Size This is the rim size that is appropriate for the tire size listed.
Inflation Pressure This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR. Curb Weight The curb weight of a vehicle is defined as the total weight of the vehicle with all fluids, including vehicle fuel, at full capacity conditions, and with no occupants or cargo loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a commercial scale before any occupants or cargo are added. Loading The actual total weight and the weight of the front and rear of your vehicle at the ground can best be determined by weighing it when it is loaded and ready for operation. The entire vehicle should first be weighed on a commer- cial scale to insure that the GVWR has not been exceeded. The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is properly distributed over front and rear axle. Weighing the vehicle may show that the GAWR of either the front or rear axles has been exceeded but the total load is within the specified GVWR. If so, weight must be shifted from front to rear or rear to front as appropriate until the specified weight limitations are met. Store the heavier items down low and be sure that the weight is distributed equally. Stow all loose items securely before driving. Improper weight distributions can have an adverse effect on the way your vehicle steers and handles and the way the brakes operate.
STARTING AND OPERATING 383
CAUTION!
Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWR. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. This could cause you to lose control. Also overloading can shorten the life of your vehicle.
TRAILER TOWING In this section you will find safety tips and information on limits to the type of towing you can reasonably do with your vehicle. Before towing a trailer carefully re- view this information to tow your load as efficiently and safely as possible. To maintain warranty coverage, follow the requirements and recommendations in this manual concerning ve- hicles used for trailer towing.
384 STARTING AND OPERATING
Common Towing Definitions The following trailer towing related definitions will assist you in understanding the following information: Gross Vehicle Weight Rating (GVWR) The GVWR is the total allowable weight of your vehicle. This includes driver, passengers, cargo and tongue weight. The total load must be limited so that you do not exceed the GVWR. Gross Trailer Weight (GTW) The GTW is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or tem- porary) loaded in or on the trailer in its ⬙loaded and ready for operation⬙ condition. The recommended way to measure GTW is to put your fully loaded trailer on a vehicle scale. The entire weight of the trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR) The GCWR is the total permissible weight of your vehicle and trailer when weighed in combination. NOTE: The GCWR rating includes a 150 lbs (68 kg) allowance for the presence of a driver. Gross Axle Weight Rating (GAWR) The GAWR is the maximum capacity of the front and rear axles. Distribute the load over the front and rear axles evenly. Make sure that you do not exceed either front or rear GAWR.
WARNING!
It is important that you do not exceed the maximum front or rear GAWR. A dangerous driving condition can result if either rating is exceeded. You could lose control of the vehicle and have an accident.
Tongue Weight (TW) The tongue weight is the downward force exerted on the hitch ball by the trailer. In most cases it should not be less than 10% or more than 15% of the trailer load. You must consider this as part of the load on your vehicle. Frontal Area The frontal area is the maximum height and maximum width of the front of a trailer. Trailer Sway Control The trailer sway control is a telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable friction associated with the telescoping motion to dampen any unwanted trailer swaying motions while traveling. Weight-Carrying Hitch A weight-carrying hitch supports the trailer tongue weight, just as if it were luggage located at a hitch ball or some other connecting point of the truck. These kind of
STARTING AND OPERATING 385
hitches are the most popular on the market today and they’re commonly used to tow small- and medium-sized trailers. Weight-Distributing Hitch A weight-distributing system works by applying lever- age through spring (load) bars. They are typically used for heavier loads, to distribute trailer tongue weight to the tow vehicle’s front axle and the trailer axle(s). When used in accordance with the manufacturers’ directions, it provides for a more level ride, offering more consistent steering and brake control thereby enhancing towing safety. The addition of a friction / hydraulic sway control also dampens sway caused by traffic and crosswinds and contributes positively to tow vehicle and trailer stability. Trailer sway control and a weight distributing (load equalizing) hitch are recommended for heavier Tongue Weights (TW) and may be required depending on Vehicle and Trailer configuration / loading to comply with gross axle weight rating (GAWR) requirements.
386 STARTING AND OPERATING
WARNING!
• An improperly adjusted Weight Distributing Hitch system may reduce handling, stability, brak- ing performance, and could result in an accident. • Weight Distributing Systems may not be compat- ible with Surge Brake Couplers. Consult with your hitch and trailer manufacturer or a reputable Rec- reational Vehicle dealer for additional information.

Fifth-Wheel Hitch A special high platform with a coupling that mounts over the rear axle of the tow vehicle in the truck bed. Connects a vehicle and fifth-wheel trailer with a coupling king pin. Gooseneck Hitch The gooseneck hitch employs a pivoted coupling arm which attaches to a ball mounted in the bed of a pickup truck. The coupling arm connects to the hitch mounted over the rear axle in the truck bed. Trailer Hitch Classification The rear bumper is intended to tow trailers up to 2,000 lbs (907 kg) without added equipment or alter- ations to the standard equipment. Your vehicle may be factory equipped for safe towing of trailers weighing over 2,000 lbs (907 kg) with the optional Trailer Tow Prep Package. See your dealer for package content.

STARTING AND OPERATING 389
NOTE: For additional trailer towing information (maxi- mum trailer weight ratings) refer to the following website addresses: • http:// www.dodge.com/towing. • http:// www.dodge.ca (Canada). Trailer and Tongue Weight Always load a trailer with 60% to 65% of the weight in the front of the trailer. This places 10% to 15% of the Gross Trailer Weight (GTW) on the tow hitch of your vehicle. Loads balanced over the wheels or heavier in the rear can cause the trailer to sway severely side to side which will cause loss of control of vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents.
390 STARTING AND OPERATING
put in or on your vehicle.
Consider the following items when computing the weight on the rear axle of the vehicle: • The tongue weight of the trailer. • The weight of any other type of cargo or equipment • The weight of the driver and all passengers. NOTE: Remember that everything put into or on the trailer adds to the load on your vehicle. Also, additional factory-installed options, or dealer-installed options, must be considered as part of the total load on your vehicle. Refer to the Tire and Loading Information plac- ard in the “Tire Safety Information” section of this manual.
Towing Requirements To promote proper break-in of your new vehicle drive- train components the following guidelines are recom- mended:
CAUTION!
• Avoid towing a trailer for the first 500 miles (805 km) of vehicle operation. Doing so may dam- age your vehicle. • During the first 500 miles (805 km) of trailer
towing, limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this manual. When towing a trailer, never exceed the GAWR, or GCWR, ratings.
WARNING!
Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible: Make certain that the load is secured in the trailer and will not shift during travel. When trailering cargo that is not fully secured, dynamic load shifts can occur that may be difficult for the driver to control. You could lose control of your vehicle and have an accident. • When hauling cargo or towing a trailer, do not over- load your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transmission, steering, suspension, chas- sis structure or tires. • Safety chains must always be used between your vehicle and trailer. Always connect the chains to the

frame or hook retainers of the vehicle hitch. Cross the chains under the trailer tongue and allow enough slack for turning corners. • Vehicles with trailers should not be parked on a grade. When parking, apply the parking brake on the tow vehicle. Put the tow vehicle automatic transmission in PARK. With four-wheel-drive vehicles, make sure the transfer case is not in neutral. Always, block or ⬙chock⬙ the trailer wheels.
• GCWR must not be exceeded. • Total weight must be distributed between the tow vehicle and the trailer such that the following four ratings are not exceeded: 1. GVWR 2. GTW 3. GAWR
392 STARTING AND OPERATING
4. Tongue weight rating for the trailer hitch utilized (This requirement may limit the ability to always achieve the 10% to 15% range of tongue weight as a percentage of total trailer weight).
− When replacing tires, refer to “Tires–General Informa- tion” for proper tire replacement procedures. Replac- ing tires with a higher load carrying capacity will not increase the vehicle’s GVWR and GAWR limits.
Towing Requirements — Tires − Do not attempt to tow a trailer while using a compact
spare tire.
− Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to “Tires–General Information” for proper tire inflation procedures.
− Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to “Tires–General Infor- mation” for the proper inspection procedure.
Towing Requirements — Trailer Brakes − Do not interconnect the hydraulic brake system or vacuum system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury.
− An electronically actuated trailer brake controller is required when towing a trailer with electronically actuated brakes. When towing a trailer equipped with a hydraulic surge actuated brake system, an electronic brake controller is not required.
− Trailer brakes are recommended for trailers over 1,000 lbs (454 kg) and required for trailers in excess of 2,000 lbs (907 kg).
STARTING AND OPERATING 393
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg) loaded, it should have its own brakes and they should be of adequate capacity. Failure to do this could lead to accelerated brake lining wear, higher brake pedal effort, and longer stopping distances.
WARNING! (Continued)
• Towing any trailer will increase your stopping distance. When towing you should allow for addi- tional space between your vehicle and the vehicle in front of you. Failure to do so could result in an accident.
WARNING!
• Do not connect trailer brakes to your vehicle’s hydraulic brake lines. It can overload your brake system and cause it to fail. You might not have brakes when you need them and could have an accident.
(Continued)
Towing Requirements — Trailer Lights & Wiring Whenever you pull a trailer, regardless of the trailer size, stop lights and turn signals on the trailer are required for motoring safety. The Trailer Tow Package may include a 4 and 7–pin wiring harness. Use a factory approved trailer harness and connector. NOTE: Do not cut or splice wiring into the vehicles wiring harness.
394 STARTING AND OPERATING
The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.

5 — Ground 6 — Left Stop/Turn 7 — Running Lamps
WARNING!
Any work done to the vehicles electrical system, or wiring, should be performed by a qualified automo- tive technician, if done improperly it may cause damage to the electrical system wiring and could result in serious or fatal injury.
Towing Tips Before setting out on a trip, practice turning, stopping and backing the trailer in an area away from heavy traffic. Automatic Transmission The “DRIVE” range can be selected when towing. How- ever, if frequent shifting occurs while in this range, the “TOW HAUL” or “OD/OFF” range should be selected.
STARTING AND OPERATING 395
NOTE: Using the “TOW HAUL” or “OD/OFF” range while operating the vehicle under heavy operating con- ditions will improve performance and extend transmis- sion life by reducing excessive shifting and heat build up. This action will also provide better engine braking. The automatic transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. Refer to the “Main- tenance Schedule” in Section 8 for the proper mainte- nance intervals. NOTE: Check the automatic transmission fluid level before towing. Tow/Haul — If Equipped To reduce potential for automatic transmission overheat- ing, turn the “TOW HAUL OD/OFF” feature ON when driving in hilly areas or shift the transmission to Drive position 2 on more severe grades.
396 STARTING AND OPERATING
Electronic Speed Control — If Equipped − Do not use in hilly terrain or with heavy loads. − When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you can get back to cruising speed.
− Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System To reduce potential for engine and transmission over- heating, take the following actions: NOTE: Engine power may be temporarily reduced in order to maintain oil and coolant temperatures under extreme trailer tow operating conditions. − City Driving When stopped for short periods of time, put transmission in neutral and increase engine idle speed.
− Highway Driving Reduce speed. − Air Conditioning Turn off temporarily.
SNOWPLOW Snowplow Prep Packages are available as a factory- installed option. These packages include components necessary to equip your vehicle with a snowplow. NOTE: Before installation of a snowplow, it is highly recommended that the owner/installer obtain and follow the recommendations contained within the current Dodge Body Builder’s Guide. See your authorized dealer, installer or snowplow manufacturer for this information. There are unique electrical systems that must be con- nected to properly assure operator safety, and to prevent overloading vehicle systems.
WARNING!
Attaching a snowplow to this vehicle could adversely affect performance of the airbag system in an acci- dent. Do not expect that the airbag will perform as described earlier in this manual

face. Lightly tighten the nuts. To avoid risk of forcing the vehicle off the jack, do not fully tighten the nuts until the vehicle has been lowered. 6. Using the wheel wrench, finish tightening the nuts using a crisscross pattern. The correct nut tightness is 135 ft lbs (183 N·m) torque for 2500/3500 single-rear wheel (SRW) models, and 145 ft lbs (197 N·m) for 3500
dual rear-wheel models. If in doubt about the correct tightness, have them checked with a torque wrench by your authorized dealer or at a service station.WARNING!
A loose tire or jack thrown forward in a collision or hard stop could injure someone in the vehicle. Al- ways stow the jack parts and the extra tire and wheel in the places provided.
7. Install wheel center cap and remove wheel blocks. Do not install chrome or aluminum wheel center caps on the spare wheel. This may result in cap damage. 8. Lower the jack to its fully closed position. If the bottle jack will not lower by turning the dial (thumbwheel) by hand, it may be necessary to use the jack drive tube in order to lower the jack. Stow the replaced tire, jack, and tools as previously described. 9. Adjust the tire pressure when possible. NOTE: Do not oil wheel studs. For chrome wheels, do not substitute with chrome plated wheel nuts. Hub Caps/Wheel Covers The hub caps must be removed before raising the vehicle off the ground. For 2500/3500 single rear-wheel (SRW) models, use the blade on the end of the lug wrench to pry the hub cap off.
Insert the blade end into the pry-off notch and carefully pop off the hub cap with a back-and-forth motion. On 3500 models with dual rear wheels (DRW), you must first remove the hub caps. The jack handle driver has a hook at one end that will fit in the pry off notch of the rear hub caps. Position the hook and pull out on the ratchet firmly. The hub cap should pop off. The wheel skins can now be removed. For the front hub cap on 3500
models use the blade on the end of the lug wrench to pry the caps off. The wheel skin can now be removed.CAUTION!
• Use a back-and-forth motion to remove the hub cap. Do not use a twisting motion when removing the hub cap, damage to the hub cap finish may occur.
(Continued)
WHAT TO DO IN EMERGENCIES 415
CAUTION! (Continued)
• The rear hub caps on the dual rear wheel has two pry-off notches. Make sure that the hook of the jack handle driver is located squarely in the cap notch before attempting to pull off.
You must use the flat end of the lug wrench to pry off the wheel skins. Insert the flat tip completely and using a back-and-forth motion, loosen the wheel skin. Repeat this procedure around the tire until the skin pops off. Replace the wheel skins first using a rubber mallet. When replacing the hub caps, tilt the cap retainer over the lugnut bolt circle and strike the high side down with a rubber mallet. Be sure that the hub caps and wheel skins are firmly seated around the wheel.
416 WHAT TO DO IN EMERGENCIES
8-Stud — Dual Rear Wheels Dual wheels are flat-mounted and 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.
Oiling Location
Slots in the wheels will assist in properly orienting the inner and outer wheels. Align these slots when assem- bling the wheels for best access to the tire valve on the inner wheel. The tires of both dual wheels must be completely off the ground when tightening, to ensure wheel centering and maximum wheel clamping. Dual wheel models require a special heavy-duty lug nut tightening adapter (included with the vehicle) to cor- rectly tighten the lug nuts. Also, when it is necessary to remove and install dual rear wheels, use a proper vehicle lifting device. NOTE: When installing a spare tire as part of a dual rear wheel end combination, the tire diameter of the two individual tires must be compared. If there is a significant difference, the larger tire should be installed in a front location. The correct direction of rotation for dual tire installations must also be observed.
These dual rear wheels should be tightened as follows:
Tightening Pattern
1. Tighten the wheel nuts in the numbered sequence to a snug fit.
WHAT TO DO IN EMERGENCIES 417
2. 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 specifications at 100 miles (160 km) and after 500 miles (800 km). 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. Wheel Nuts All wheel nuts should be tightened occasionally to elimi- nate 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 nuts should first be firmly seated against the wheel. The nuts should then be tightened to recommended torque. Tighten the nuts to final torque in increments. Progress around the bolt

For convenience in checking the spare tire inflation, stow with the valve stem toward the rear of the vehicle. Attach the wheel wrench to the extension tube. Rotate the winch mechanism until the wheel is drawn into place against the underside of the vehicle. Continue to rotate until you feel the winch mechanism slip, or click three or four times. It cannot be overtightened. Push against the tire several times to be sure it is firmly in place.
HOISTING A conventional floor jack may be used at the jacking locations. Refer to the graphics that show jacking loca- tions. However, a floor jack or frame hoist must never be used on any other parts or the underbody.
CAUTION!
Never use a floor jack directly under the differential housing of a loaded truck or damage to your vehicle may result.
JUMP-STARTING PROCEDURES Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic transmis- sion cannot be started this way. Also, there is a greater risk of an accident when a vehicle is being pushed or towed. If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly, so follow this procedure carefully.

WHAT TO DO IN EMERGENCIES 421
FREEING A STUCK VEHICLE If the vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the shift lever rhythmically between DRIVE and REVERSE, while ap- plying slight pressure to the accelerator. In general, the least amount of accelerator pedal pressure to maintain the rocking motion without spinning the wheels or racing the engine, is most effective. Racing the engine or spinning the wheels, due to the frustration of not freeing the vehicle, may lead to transmission over- heating and failure. Allow the engine to idle with the shift lever in NEUTRAL for at least one minute after every five rocking-motion cycles. This will minimize overheating and reduce the risk of transmission failure during prolonged efforts to free a stuck vehicle.

EMERGENCY TOW HOOKS — IF EQUIPPED Your vehicle may be equipped with emergency tow hooks. NOTE: For off-road recovery, it is recommended to use both of the front tow hooks to minimize the risk of damage to the vehicle.
WARNING!
• Chains are not recommended for freeing a stuck vehicle. Chains may break, causing serious injury or death. • Stand clear of vehicles when pulling with tow hooks. Tow straps and chains may break, causing serious injury.
CAUTION!
Tow hooks are for emergency use only to rescue a vehicle stranded off-road. Do not use tow hooks for tow truck hookup or highway towing. You could damage your vehicle.
TOWING A DISABLED VEHICLE Proper towing or lifting equipment is required to prevent damage to your vehicle. Use only tow bars and other equipment designed for the purpose, following equip- ment manufacturer’s instructions. Use of safety chains is mandatory. Attach a tow bar or other towing device to the main structural members of the vehicle, not to bumpers or associated brackets. State and local laws applying to vehicles under tow must be observed.
4-Wheel Drive Vehicles
CAUTION!
To avoid damage to the transfer case while towing, always use one of the following methods. • The transfer case must be in the neutral position, and the transmission must be in PARK to tow a 4-Wheel Drive vehicle with one end of the vehicle raised. • The manufacturer recommends towing with all wheels OFF the ground. Acceptable methods are to tow the vehicle on a flatbed or with one end of vehicle raised and the opposite end on a towing dolly.
WHAT TO DO IN EMERGENCIES 423
2–Wheel Drive Vehicles Provided that the transmission is operable, tow with the transmission in NEUTRAL and the ignition key in the OFF position along with the front wheels raised and the rear wheels on the ground. Speed must not exceed 30 mph (50 km/h) and distance must not exceed 15 miles (25 km). If the vehicle is to be towed faster than 30 mph (50 km/h) or more than 15 miles (25 km) the vehicle must be towed with the rear wheels raised and the front wheels on the ground. It may also be towed on a flatbed or with the front wheels raised and the rear wheels on a dolly.
CAUTION!
Towing faster than 30 mph (50 km/h) or for more than 15 miles (25 km) can cause severe damage to the transmission.

428 MAINTAINING YOUR VEHICLE
ONBOARD DIAGNOSTIC SYSTEM (OBD II) Your vehicle is equipped with a sophisticated onboard diagnostic system called OBDII. This system monitors the performance of the emissions, engine, and automatic transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emis- sions well within current government regulations. If any of these systems require service, the OBD II system will turn on the Malfunction Indicator Light (MIL). It will also store diagnostic codes and other information to assist your service technician in making repairs. Al- though your vehicle will usually be drivable and not need towing, see your authorized dealer for service as soon as possible.
CAUTION!
• Prolonged driving with the MIL on could cause further damage to the emission control system. It could also affect fuel economy and drivability. The vehicle must be serviced before any emissions tests can be performed. • If the MIL is flashing, severe catalytic converter damage and power loss will soon occur. Immedi- ate service is required.
Loose Fuel Filler Cap Message
If the vehicle’s diagnostic system determines that the fuel filler cap in loose, improperly installed, or damaged, a GASCAP message will be displayed in the instrument cluster. Tighten the gas cap until a “clicking” sound is heard. This is an indication that the gas cap is properly tightened. Press the odometer reset button to turn the message off. If the problem persists, the message will
appear the next time the vehicle is started. This might indicate a damaged cap. If the problem is detected twice in a row, the system will turn on the MIL. Resolving the problem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS In some localities, it may be a legal requirement to pass an inspection of your vehicle’s emissions control system. Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte- nance (I/M), this check verifies the Malfunction Indicator Light (MIL) is functioning and is not on when the engine is running, and that the OBD II system is ready for testing. Normally, the OBD II system will be ready. The OBD II system may not be ready if your vehicle was recently
MAINTAINING YOUR VEHICLE 429
serviced, recently had a dead battery or a battery replace- ment. If the OBD II system should be determined not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition key-actuated test, which you can use prior to going to the test station. To check if your vehicle’s OBD II system is ready, you must do the following: 1. Insert your ignition key into the ignition switch. 2. Turn the ignition to the ON position, but do not crank or start the engine. 3. If you crank or start the engine, you will have to start this test over. 4. As soon as you turn your key to the ON position, you will see the MIL symbol come on as part of a normal bulb check.
430 MAINTAINING YOUR VEHICLE
5. Approximately 15 seconds later, one of two things will happen:
a. The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is not ready and you should not proceed to the I/M station. b. The MIL will not flash at all and will remain fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is ready and you can proceed to the I/M station.
If your OBD II system is not ready, you should see your authorized dealer or repair facility. If your vehicle was recently serviced or had a battery failure or replacement, you may need to do nothing more than drive your vehicle as you normally would in order for your OBD II system to update. A recheck with the above test routine may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is ready or not, if the MIL is illuminated during normal vehicle operation you should have your vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL is on with the engine running.
REPLACEMENT PARTS Use of genuine MOPAR威 parts for normal/scheduled maintenance and repairs is highly recommended to en- sure the designed performance. Damage or failures caused by the use of non-MOPAR威 parts for maintenance and repairs will not be covered by the manufacturer’s warranty.
DEALER SERVICE Your authorized dealer has the qualified service person- nel, special tools and equipment to perform all service operations in an expert manner. Service Manuals are available which include detailed service information for
your vehicle. Refer to these manuals before attempting any procedure yourself. NOTE: systems can result against you.
Intentional tampering with emissions control in civil penalties being assessed
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 the required maintenance services determined by the engineers who designed your vehicle.
MAINTAINING YOUR VEHICLE 431
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 lubrication of your vehicle’s engine, the engine oil must be maintained at the correct level. The best time to check the engine oil level is about five minutes after a fully warmed up 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. Always maintain the oil level within the SAFE zone on the
432 MAINTAINING YOUR VEHICLE
dipstick. Adding one quart of oil when the reading is at the bottom of the SAFE zone will result in a reading at the top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause oil aeration or loss of oil pressure. This could damage your engine.
Change Engine Oil Refer to the “Maintenance Schedule” in Section 8 for the proper maintenance intervals. Engine Oil Selection For best performance and maximum protection under all types of operating conditions, the manufacturer only recommends engine oils that are API Certified and meet the requirements of Chrysler Material Standard MS-6395.
American Petroleum Institute (API) Engine Oil Identification Symbol
This symbol means that the oil has been certified by the American Petroleum Institute (API). The manufacturer only recommends API Certified engine oils.
Engine Oil Viscosity (SAE Grade) SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. The engine oil filler cap also shows the recommended engine oil viscosity for your engine. For information on engine oil filler cap location, refer to “Engine Compartment” in this section.
NOTE: For 2500/3500 trucks with a 5.7L engine oper- ating under a gross combined weight rating of 14,000 lbs (6 350 kg) or greater, SAE 5W-30 engine oil is recom- mended for all operating temperatures. 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 You may use synthetic engine oils if the recommended oil quality requirements are met, and the recommended maintenance intervals for oil and filter changes are followed. Materials Added to Engine Oil Do not add any supplemental materials, other than leak detection dyes, to the engine oil. Engine oil is an engi- neered product and its performance may be impaired by supplemental additives.
