each tire to the vehicle’s recommended cold placard pressure value. The system will automatically update and the Tire Pressure Monitoring Lamp 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 seconds and will remain on solid when a system fault is detected. The system fault will also sound a chime. If the ignition

switch is cycled, this sequence will repeat, providing 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 TPMS 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 tire pressure moni- toring sensors. NOTE: Your vehicle is equipped with a non-matching full size spare wheel and tire assembly.

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 switch 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 switch 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.

422 STARTING AND OPERATING Tire Pressure Monitor System (TPMS) Tire Light Load Inflation Switch Description (2500 Models) – 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 and rear cold tire inflation pressures for the vehicle when operating in the Max Load condition. A Supple- mental Tire Pressure Information label is also available defining Light Load tire inflation pressures when oper- ating 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.

STARTING AND OPERATING 423

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.

Tire Light Load Inflation Switch

424 STARTING AND OPERATING

• 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 425
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

FUEL REQUIREMENTS

3.7L and 4.7L Engine

All engines (except 5.7L engines) are de- signed to meet all emissions regulations and provide excellent fuel economy and performance when using high quality un- leaded “regular” gasoline having an oc- tane rating of 87. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines. 5.7L Engine

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

STARTING AND OPERATING 427
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. Poor quality gasoline can cause problems such as hard starting, stalling, and hesitations. If you experi- ence these symptoms, try another brand of gasoline before considering service for the vehicle. Over 40 auto manufacturers worldwide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) which define fuel properties necessary to deliver enhanced emissions, performance, and durability for your vehicle. The manufacturer recom- mends the use of gasoline that meets the WWFC speci- fications if they are available.

428 STARTING AND OPERATING 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. The manufacturer supports the use of reformulated gaso- lines. Properly blended reformulated gasolines will pro- vide excellent performance and durability for the 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 gasoline 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 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 corrosion To 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

STARTING AND OPERATING 429
blended with MMT provides no performance advantage beyond gasoline of the same octane number without MMT. Gasoline blended with MMT reduces spark plug life and reduces emissions 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 his/her 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 gasoline sold in the United States is 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.

430 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 perfor- mance and 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.

(Continued)

CAUTION! (Continued)

• The use of fuel additives, which are now being sold as octane enhancers are not recommended. Most of these products contain high concentra- tions 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

STARTING AND OPERATING 431

WARNING! (Continued)

• Guard against carbon monoxide with proper maintenance. Have the exhaust system inspected every time the vehicle is raised. Have any abnor- mal conditions repaired promptly. Until repaired, drive with all side windows fully open.

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.

432 STARTING AND OPERATING FLEXIBLE FUEL (4.7L ENGINE ONLY) — IF EQUIPPED

E85 General Information The information in this section is for Flexible Fuel Ve- hicles (FFV) only. These vehicles can be identified by the unique fuel filler door label that states Ethanol (E85) or Unleaded Gasoline Only. This section 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.

E85 Fuel Cap

CAUTION!

Only vehicles with the E85 fuel filler door label can operate on E85.

STARTING AND OPERATING 433

WARNING!

Ethanol vapors are extremely flammable and could cause serious personal injury. Never have any smok- ing materials lit in or near the vehicle when remov- ing the fuel filler tube cap (gas cap) or filling the tank. Do not use E85 as a cleaning agent and never use it near an open flame.

Fuel Requirements If your vehicle is E85 compatible, it will operate on unleaded gasoline with an octane rating of 87, or E85
fuel, or any mixture of these two fuels. For best results, a refueling pattern that avoids alternat- ing between E85 and unleaded gasoline is recom- mended. When you do switch fuel types, it is recommended that: • you do not add less than 5 gal (19 L) when refueling

E85 Badge

Ethanol Fuel (E85) E85 is a mixture of approximately 85% fuel ethanol and 15% unleaded gasoline.

434 STARTING AND OPERATING

• you drive the vehicle immediately after refueling for at

least 5 miles (8 km)

Observing these precautions will avoid possible hard starting and/or significant deterioration in driveability during warm up. NOTE: • Use seasonally adjusted E85 fuel (ASTM D5798). With non-seasonally adjusted E85 fuel, you may experience hard starting and rough idle following start up even if the above recommendations are followed, especially when the ambient temperature is below 32°F (0°C). • Some additives used in regular gasoline are not fully compatible with E85 and may form deposits in your engine. To eliminate driveability issues that may be caused by these deposits, a supplemental gasoline additive, such as MOPAR威 Injector Cleanup or Techron may be used.

Selection Of Engine Oil For Flexible Fuel Vehicles (E85) and Gasoline Vehicles FFV vehicles operated on E85 require specially formu- lated engine oils. These special requirements are included in MOPAR威 engine oils, and in equivalent oils meeting Chrysler Specification MS-6395. The manufacturer only recommends engine oils that are API Certified and meet the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex- tensive fleet testing, to provide additional protection to Chrysler Group LLC engines. Use MOPAR威 or an equivalent oil meeting the specification MS-6395. Starting The characteristics of E85 fuel make it unsuitable for use when ambient temperatures fall below 0°F (-18°C). In the range of 0°F (-18°C) to 32°F (0°C), you may experience an increase in the time it takes for your engine to start, and a deterioration in driveability (sags and/or hesitations) until the engine is fully warmed up.

NOTE: Use of the engine block heater (if equipped) is beneficial for E85 startability when the ambient tempera- ture is less than 32°F (0°C). Cruising Range Because E85 fuel contains less energy per gallon/liter than gasoline, you will experience an increase in fuel consumption. You can expect your miles per gallon (mpg)/miles per liter and your driving range to decrease by about 30%, compared to gasoline operation. Replacement Parts Many components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that your vehicle is serviced with correct ethanol com- patible parts.

STARTING AND OPERATING 435

CAUTION!

Replacing fuel system components with non-ethanol compatible components can damage your vehicle.

Maintenance If you operate the vehicle using E85 fuel, follow the maintenance schedule section of this manual.

CAUTION!

Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect driveability.

436 STARTING AND OPERATING ADDING FUEL The fuel filler cap (gas cap) is located behind the fuel filler door, on the left side of the vehicle. Open the fuel door and remove the fuel cap by turning it counter- clockwise.

If the vehicles 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/felt. 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.

438 STARTING AND OPERATING 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. 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 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. 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.

STARTING AND OPERATING 439
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 the front and rear axle. Weigh- ing 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.

440 STARTING AND OPERATING

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 review 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.

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.

STARTING AND OPERATING 441

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

442 STARTING AND OPERATING 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 manufacturer’s directions, it pro- vides 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 GAWR requirements.

NOTE: For additional trailer towing information (maxi- mum trailer weight ratings) refer to the following website addresses: • http:// www.dodge.com. • 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 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 the vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents.

• 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 “Tire Safety Information/Tire and Loading In- formation Placard” in “Starting and Operating” for fur- ther information.

Consider the following items when computing the weight on the rear axle of the vehicle: • The tongue weight of the trailer

Towing Requirements To promote proper break-in of your new vehicle drive- train components the following guidelines are recom- mended:

CAUTION!

• Do not tow a trailer at all during the first 500 miles (805 km) the new vehicle is driven. The engine, axle or other parts could be damaged. • Then, during the first 500 miles (805 km) that a trailer is towed, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This helps the engine and other parts of the vehicle wear in at the heavier loads.

STARTING AND OPERATING 447

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 overload your vehicle or trailer. Overloading can cause a loss of control, poor performance or dam- age to brakes, axle, engine, transmission, steering, suspension, chassis structure or tires.

448 STARTING AND OPERATING

WARNING! (Continued)

• 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 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 so that the following four ratings are not exceeded:

sures before trailer usage.

• Check for signs of tire wear or visible tire damage before towing a trailer. Refer to “Tires – General Information” in “Starting and Operating” for the proper inspection procedure. • When replacing tires, refer to “Tires – General Infor- mation” in “Starting and Operating” for proper tire replacement procedures. Replacing tires with a higher load carrying capacity will not increase the vehicle’s GVWR and GAWR limits.

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).

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.

• 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. • 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.

Integrated Trailer Brake Module – If Equipped Your vehicle may have a Integrated Trailer Brake Module for electric trailer brakes. NOTE: This module is designed for only electric trailer brakes. To determine the type of brakes on your trailer, check with your trailer manufacturer or dealer.

1 — GAIN/Brake Output Power Display 2 — Manual Brake Control Lever 3 — Trailer Brake Status Indicator Light 4 — GAIN Adjustment Buttons The user interface consists of the following: GAIN/ Brake Output Power Display Shows the current GAIN setting.

This display may also be used to display diagnostic information, if needed. • SC — Short Circuit to Ground • Sb — Short to Battery • CF — Controller Fault – If this message appears on the

display, see your authorized dealer.

When the vehicle brakes are applied, the display will no longer show GAIN and will change to the output to the trailer brakes. Manual Brake Control Lever Slide the manual brake control lever to the right to activate power to the trailer’s electric brakes independent of the tow vehicle’s brakes. If the manual brake control lever is activated while the brake is also applied, the greater of the two inputs determines the power sent to the trailer brakes.

STARTING AND OPERATING 451
The trailer and the vehicle’s brake lamps will come on when either vehicle braking or manual trailer brakes are applied. Trailer Brake Status Indicator Light This light indicates the trailer electrical connection status. If no electrical connection is detected after the ignition is turned on, pressing the GAIN adjustment button or sliding the manual brake control lever will display the GAIN setting for 10 seconds and the “Trailer Brake Status Indicator Light” will not be displayed. If a fault is detected in the trailer wiring or the Integrated Trailer Brake Module (ITBM), the “Trailer Brake Status Indicator Light” will flash. GAIN Adjustment Buttons (+/-) Pressing these buttons will adjust the brake control power output to the trailer brakes in 0.5 increments. The

452 STARTING AND OPERATING GAIN setting can be increased to a maximum of 10 or decreased to a minimum of 0 (no trailer braking). GAIN The GAIN setting is used to set the trailer brake control for the specific towing condition and should be changed as towing conditions change. Changes to towing condi- tions include trailer load, vehicle load, road conditions and weather. Adjusting GAIN NOTE: This should only be performed in a traffic free environment at speeds of approximately 20–25 mph (30–40 km/h). 1. Make sure the trailer brakes are in good working condition, functioning normally, and properly adjusted. See your trailer dealer if necessary. 2. Hook up the trailer and make the electrical connec- tions according to the trailer manufacturer’s instructions.

3. When a trailer with electric brakes is plugged in, the GAIN setting will illuminate. 4. Use the GAIN adjustment (+/-) buttons to increase or decrease the GAIN setting to the desired starting point. A GAIN setting of 6 is a good starting point for heavier loads. 5. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20–25 mph (30–40 km/h) and squeeze the manual brake control lever completely. 6. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels turn freely, increase the GAIN setting. Repeat Steps 5 and 6 until the GAIN setting is at a point just below trailer wheel lockup. If towing a heavier trailer, trailer wheel lockup may not be attainable even with the maximum GAIN setting of 10.

EVIC Display Messages The trailer brake control interacts with the Electronic Vehicle Information Center (EVIC). Display messages, along with a single chime, will be displayed when a malfunction is determined in the trailer connection, trailer brake control, or on the trailer. Refer to “Electronic Vehicle Information Center” in “Understanding Your Instrument Panel” for further information.

CAUTION!

Connecting a trailer that is not compatible with the ITBM system may result in reduced or complete loss of trailer braking. There may be a increase in stop- ping distance or trailer instability which could result in damage to your vehicle, trailer, or other property.

STARTING AND OPERATING 453

WARNING!

Connecting a trailer that is not compatible with the ITBM system may result in reduced or complete loss of trailer braking. There may be a increase in stop- ping distance or trailer instability which could result in personal injury.

NOTE: A aftermarket controller may be available for use with trailers with air or electric-over-hydraulic trailer brake systems. To determine the type of brakes on your trailer and the availability of controllers, check with your trailer manufacturer or dealer. Towing Requirements – Trailer Lights and Wiring Whenever you pull a trailer, regardless of the trailer size, stop lights and turn signals on the trailer are required for motoring safety.

454 STARTING AND OPERATING The Trailer Tow Package will include a four and seven- pin wiring harness. Use a factory approved trailer har- ness and connector. NOTE: Do not cut or splice wiring into the vehicle’s wiring harness. The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.

Four-Pin Connector 4 — Park 5 — Left Stop/Turn 6 — Right Stop/Turn

STARTING AND OPERATING 455

WARNING!

Any work done to the vehicle’s 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 up 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, select “TOW/HAUL” mode (if equipped) or select a lower gear using the Electronic Range Select (ERS) feature.

1 — Battery 2 — Backup Lamps 3 — Right Stop/Turn 4 — Electric Brakes

Seven-Pin Connector 5 — Ground 6 — Left Stop/Turn 7 — Running Lamps

456 STARTING AND OPERATING NOTE: Using “TOW/HAUL” mode or a lower gear range while operating the vehicle under heavy operating conditions will improve performance and extend trans- mission 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 “Mainte- nance Schedule” for the proper maintenance intervals. NOTE: Check the automatic transmission fluid level before towing. Tow/Haul To reduce potential for automatic transmission overheat- ing, turn the “TOW/HAUL” feature ON when driving in hilly areas, or select a lower gear range (using the Electronic Range Select (ERS) feature) on more severe grades.

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: − City Driving When stopped for short periods of time, shift the trans- mission into NEUTRAL and increase engine idle speed. − Highway Driving Reduce speed.

− Air Conditioning Turn off temporarily.

SNOWPLOW

1500 Models Only

NOTE: Do not use this model vehicle for snowplow applications.

WARNING!

Snowplows and other aftermarket equipment should not be added to the front end of your vehicle. The airbag crash sensors may be affected by the change in the front end structure. The airbags could deploy unexpectedly or could fail to deploy during a colli- sion resulting in serious injury or death.

STARTING AND OPERATING 457

CAUTION!

Using this vehicle for snowplow applications can cause damage to the vehicle.

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

2500/3500 Models Only 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

458 STARTING AND OPERATING Dodge Body Builders 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 prevent overloading vehicle systems.

Snowplow Prep Package Model Availability For Information about snowplow applications visit www.dodge.com or refer to the current Dodge Body Builders Guide. 1. The maximum number of occupants in the truck should not exceed two.

2. The total GVWR or the Front GAWR or the Rear GAWR should never be exceeded. 3. Cargo capacity will be reduced by the addition of options or passengers, etc. The loaded vehicle weight, including the snowplow system, all aftermarket accessories, driver, passengers, options, and cargo, must not exceed either the Gross Vehicle Weight (GVWR) or Gross Axle Weight (GAWR) ratings. These weights are specified on the Safety Com- pliance Certification Label on the driver’s side door opening. NOTE: Detach the snowplow when transporting pas- sengers. Vehicle front end wheel alignment was set to specifica- tions at the factory without consideration for the weight of the plow. Front end toe-in should be checked and reset

STARTING AND OPERATING 459
if necessary at the beginning and end of the snowplow season. This will help prevent uneven tire wear. The blade should be lowered whenever the vehicle is parked. Maintain and operate your vehicle and snowplow equip- ment following the recommendations provided by the specific snowplow manufacturer. Over the Road Operation With Snowplow Attached The blade restricts air flow to the radiator and causes the engine to operate at higher than normal temperatures. Therefore, when transporting the plow, angle the blade completely and position it as low as road or surface conditions permit. Do not exceed 40 mph (64 km/h). The operator should always maintain a safe stopping distance and allow adequate passing clearance.

460 STARTING AND OPERATING Operating Tips Under ideal snow plowing conditions, 20 mph (32 km/h) should be maximum operating speed. The operator should be familiar with the area and surface to be cleaned. Reduce speed and use extreme caution when plowing unfamiliar areas or under poor visibility. NOTE: During snowplow usage on vehicles equipped with outside temperature display, the display may show higher temperatures than the outside ambient tempera- ture. The higher displayed temperature is due to blocked or reduced airflow to the underhood ambient tempera- ture sensor caused by the snowplow. In addition, on vehicles equipped with Automatic Temperature Control (ATC), it is suggested that the interior cabin temperature be manually controlled should the system not perform as desired while in automatic mode. Both the outside tem- perature display and ATC operation will return to nor- mal when the snowplow is removed.

General Maintenance Snowplows should be maintained in accordance with the plow manufacturer’s instructions. Keep all snowplow electrical connections and battery terminals clean and free of corrosion. When plowing snow, to avoid transmission and drive- train damage, the following precautions should be ob- served. • Operate with transfer case in 4L when plowing small or congested areas where speeds are not likely to exceed 15 mph (24 km/h). At higher speeds operate in 4H. • Vehicles with automatic transmissions should use 4L range when plowing deep or heavy snow for extended periods of time to avoid transmission overheating.

• Do not shift the transmission unless the engine has returned to idle and wheels have stopped. Make a practice of stepping on the brake pedal before shifting the transmission.

RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.)

CAUTION!

Front or rear wheel lifts should not be used. Internal damage to the transmission or transfer case will occur if a front or rear wheel lift is used when recreational towing.

Raising the vehicle higher than necessary can make the vehicle unstable and cause an accident. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire.

5. Remove the wheel nuts and pull the wheel off. On single rear-wheel (SRW) trucks, install the spare wheel and wheel nuts with the cone shaped end of the wheel nuts toward the wheel. On 3500 dual rear-wheel models (DRW) the wheel nuts are a two-piece assembly with a flat face. Lightly tighten the wheel nuts. To avoid the risk of forcing the vehicle off the jack, do not fully tighten the wheel nuts until the vehicle has been lowered. 6. Using the wheel wrench, finish tightening the wheel nuts using a crisscross pattern. The correct wheel nut tightness is 130 ft lbs (177 N·m) torque (1500 Series), 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 tight- ness, 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 the wheel center cap and remove the 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 — If Equipped 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.

488 WHAT TO DO IN EMERGENCIES

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. • 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 lug nut 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.

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 wheel nuts should first be firmly seated against the wheel. The wheel nuts should then be tightened to recom- mended 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 tight- ened until final torque is achieved. Recommended torques are shown in the following chart.

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

WHAT TO DO IN EMERGENCIES 489
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.

490 WHAT TO DO IN EMERGENCIES These dual rear wheels should be tightened as follows:

Tightening Pattern

1. Tighten the wheel nuts in the numbered sequence to a snug fit. 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. To Stow The Flat Or Spare

NOTE: Vehicles equipped with aluminum wheels can- not be stored under the vehicle because the wheel retainer will not fit through the wheel pilot hole. Secure the flat tire in the bed of the truck. Have the flat tire repaired or replaced immediately.

WARNING!

A loose tire thrown forward in a collision or hard stop could injure the occupants in the vehicle. Have the deflated (flat) tire repaired or replaced immedi- ately.

Turn the wheel so that the valve stem is down. Slide the wheel retainer through the center of the wheel and position it properly across the wheel opening. 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 If your vehicle has a discharged battery it can be jump- started using a set of jumper cables and a battery in another vehicle or by using a portable battery booster pack. Jump-starting can be dangerous if done improperly so please follow the procedures in this section carefully.

492 WHAT TO DO IN EMERGENCIES NOTE: When using a portable battery booster pack follow the manufacturer’s operating instructions and precautions.

CAUTION!

Do not use a portable battery booster pack or any other booster source with a system voltage greater than 12 Volts or damage to the battery, starter motor, alternator or electrical system may occur.

WARNING!

When temperatures are below the freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump-starting because the battery could rup- ture or explode and cause personal injury. Battery temperature must be brought above the freezing point before attempting a jump-start.

Preparations for Jump-Start The battery in your vehicle is located in the front of the engine compartment, behind the left headlight assembly. NOTE: The positive battery post is covered with a protective cap. Lift up on the cap to gain access to the positive battery post.

Positive Battery Post

WARNING!

• Take care to avoid the radiator cooling fan when- ever the hood is raised. It can start anytime the ignition switch is on. You can be injured by moving fan blades. • Remove any metal jewelry such as watch bands or bracelets that might make an inadvertent electrical contact. You could be seriously injured. • Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep open flames or sparks away from the battery.

1. Set the parking brake, shift the automatic transmission into PARK and turn the ignition to LOCK. 2. Turn off the heater, radio, and all unnecessary electri- cal accessories.

WHAT TO DO IN EMERGENCIES 493
3. If using a another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the ignition is OFF.

WARNING!

Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result.

Jump-Starting Procedure

WARNING!

Failure to follow this procedure could result in per- sonal injury or property damage due to battery ex- plosion.

494 WHAT TO DO IN EMERGENCIES

CAUTION!

WARNING!

Failure to follow these procedures could result in damage to the charging system of the booster vehicle or the discharged vehicle.

1. Connect the positive (+) end of the jumper cable to the positive (+) post of the discharged vehicle. 2. Connect the opposite end of the positive (+) jumper cable to the positive (+) post of the booster battery. 3. Connect the negative end (-) of the jumper cable to the negative (-) post of the booster battery. 4. Connect the opposite end of the negative (-) jumper cable to a good engine ground (exposed metal part of the discharged vehicle’s engine) away from the battery and the fuel injection system.

Do not connect the cable to the negative post (-) of the discharged battery. The resulting electrical spark could cause the battery to explode and could result in personal injury.

5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start the engine in the vehicle with the discharged battery. Once the engine is started, remove the jumper cables in the reverse sequence: 6. Disconnect the negative (-) jumper cable from the engine ground of the vehicle with the discharged battery. 7. Disconnect the negative end (-) of the jumper cable from the negative (-) post of the booster battery.

8. Disconnect the opposite end of the positive (+) jumper cable from the positive (+) post of the booster battery. 9. Disconnect the positive (+) end of the jumper cable from the positive (+) post of the discharged vehicle. If frequent jump-starting is required to start your vehicle you should have the battery and charging system in- spected at your authorized dealer.

CAUTION!

Accessories that can be plugged into the vehicle power outlets draw power from the vehicle’s battery, even when not in use (i.e., cellular phones, etc.). Eventually, if plugged in long enough, the vehicle’s battery will discharge sufficiently to degrade battery life and/or prevent the engine from starting.

WHAT TO DO IN EMERGENCIES 495

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. Allow the engine to idle with the transmission 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 pro- longed efforts to free a stuck vehicle.

496 WHAT TO DO IN EMERGENCIES

CAUTION!

• When “rocking” a stuck vehicle by moving be- tween 1st and REVERSE, do not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may result. • Revving the engine or spinning the wheels too fast may lead to transmission overheating and failure. It can also damage the tires. Do not spin the wheels above 30 mph (48 km/h).

WARNING!

Fast spinning tires can be dangerous. Forces gener- ated by excessive wheel speeds may cause damage, or even failure, of the axle and tires. A tire could explode and injure someone. Do not spin your vehi- cle’s wheels faster than 30 mph (48 km/h) or for longer than 30 seconds continuously without stop- ping when you are stuck and do not let anyone near a spinning wheel, no matter what the speed.

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

WHAT TO DO IN EMERGENCIES 497
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. Four-Wheel Drive Vehicles The transfer case must be in the neutral position and the transmission must be in PARK to tow a four-wheel drive vehicle with one end of the vehicle raised. Refer to “Recreational Towing” in “Starting and Operating” for further information. 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.

498 WHAT TO DO IN EMERGENCIES

CAUTION!

CAUTION!

Failure to follow these towing methods could result in damage to the transfer case. Such damage is not covered by the New Vehicle Limited Warranty.

Two-Wheel Drive Vehicles Provided that the transmission is operable, tow with the transmission in NEUTRAL and the ignition key in the LOCK position along with the front wheels raised and the rear wheels on the ground. Speed must not exceed 30 mph (50 km/h) and the distance must not exceed 15 miles (25 km).

Towing faster than 30 mph (50 km/h) or for more than 15 miles (25 km) can cause severe damage to the transmission. Such damage is not covered by the New Vehicle Limited Warranty.

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.
