INSTALLATION OF RADIO TRANSMITTING

EQUIPMENT

Special design considerations are incorporated into this vehi-cles electronic system to provide immunity to radio frequencysignals. Mobile two-way radios and telephone equipment mustbe installed properly by trained personnel. The following mustbe observed during installation.

The positive power connection should be made directly to thebattery and fused as close to the battery as possible. Thenegative power connection should be made to body sheetmetal adjacent to the negative battery connection. This con-nection should not be fused.

Antennas for two-way radios should be mounted on the roof orthe rear area of the vehicle. Care should be used in mountingantennas with magnet bases. Magnets may affect the accu-racy or operation of the compass on vehicles so equipped.

The antenna cable should be as away from the vehicle wiring wshielded coaxial cable.

Carefully match the antenna andlow Standing Wave Ratio (SWR).

Mobile radio equipment with outmal may require special precautio

All installations should be checkbetween the communications e

electronic systems.

A MESSAGE FROM CHRYSLER GROUP LLCChrysler Group LLC and Cummins welcome you as aCummins turbocharged diesel-powered truck owner.Your diesel truck will sound, feel, drive, and operatedifferently from a gasoline-powered truck. It is important

that you read and understand this manual.

Almost 100% of the heavy duty trucks in the UnitedStates and Canada are diesel-powered because of the fueleconomy, rugged durability, and high torque which per-mits pulling heavy loads. Cummins engines power wellover half of these trucks. Now this same technology andproven performance is yours in your truck equippedwith the Cummins turbocharged diesel engine.

You may find that some of the starting, operating, andmaintenance procedures are different. However, they aresimple to follow and careful adherence to them willensure that you take full advantage of the features of thisengine.

To Release The Steering Wheel Lock

Insert the key fob into the ignition switch and start theengine. If the key fob is difficult to turn, move the wheelslightly to the right or left to disengage the lock.

The Cummins

turbocharged diesel engine does notrequire a break-in period due to its construction. Normaloperation is allowed, providing the following recommen-dations are followed:

Warm up the engine before placing it under load.

Do not operate the engine at idle for prolongedperiods.

Use the appropriate transmission gear to preventengine lugging.

Observe vehicle oil pressure and temperature indica-tors.

Check the coolant and oil levels frequently.

STARTING PROCEDURESBefore starting your vehicle, adjust your seat, adjust bothinside and outside mirrors, and fasten your seat belts.

The starter should not be operated for more than 15-second intervals. Waiting a few minutes between such

intervals will protect the starter from overheating.

WARNING!

Do not leave children or animals inside parkedvehicles in hot weather. Interior heat build up maycause serious injury or death.

Leaving children in a vehicle unattended is dan-gerous for a number of reasons. A child or others

could be seriously or fatally injured. Childrenshould be warned not to touch the parking brake,brake pedal or the shift lever. Do not leave the keyin the ignition. A child could operate power win-dows, other controls, or move the vehicle.

WARNING!

Starting fluids or flammable liquids are never to beused in the Cummins diesel engine (see Warninglabel). Never pour diesel fuel, flammable liquid,starting fluids (ether) into the air cleaner canister, air

Battery Blanket UsageA battery loses 60% of its cranking power as the batterytemperature decreases to 0F (-18C). For the same de-crease in temperature, the engine requires twice as muchpower to crank at the same RPM. The use of 120 VACpowered battery blankets will greatly increase starting

capability at low temperatures. Suitable battery blanketsare available from your authorized MOPAR dealer.

Engine Warm-UpAvoid full throttle operation when the engine is cold.When starting a cold engine, bring the engine up tooperating speed slowly to allow the oil pressure tostabilize as the engine warms up.

NOTE: High-speed, no-load running of a cold enginecan result in excessive white smoke and poor engineperformance. No-load engine speeds should be keptunder 1,200 RPM during the warm-up period, especiallyin cold ambient temperature conditions.

Stopping The EngineIdle the engine a few minutes before routine shutdown.After full load operation, idle the engine three to fiveminutes before shutting it down. This idle period will

allow the lubricating oil and coolant to carry excess heataway from the combustion chamber, bearings, internalcomponents, and turbocharger. This is especially impor-tant for turbocharged, charge air-cooled engines.

The torque converter clutch will not engage, and thetransmission will not shift to sixth gear, until thetransmission fluid and engine coolant are warm [usu-ally after 1 to 3 miles (1.6 to 4.8 km) of driving].Because sixth gear is disabled, and engine speed is

higher when the torque converter clutch is not en-gaged, it may seem as if the transmission is notshifting properly when cold. This is normal. Using theElectronic Range Select (ERS) feature, when the trans-mission is sufficiently warm, will demonstrate that thetransmission is able to shift into and out of Overdrive.

If the vehicle has not been driven for several days, thefirst few seconds of operation after shifting the trans-

mission into gear may seem sluggish. This is due to thefluid partially draining from the torque converter intothe transmission. This condition is normal and will notcause damage to the transmission. The torque converterwill refill within five seconds after starting the engine.

performance.

The purpose of the SCR system is to reduce levels of NOx(oxides of nitrogen emitted from engines) that are harm-ful to our health and the environment to an almostnear-zero level. Small quantities of Diesel Exhaust Fluid(DEF) are injected into the exhaust upstream of a catalystwhere, when vaporized, convert smog-forming nitrogenoxides (NOx) into harmless nitrogen (N2) and watervapor (H2O), two natural components of the air webreathe. You can operate with the comfort that yourvehicle is contributing to a cleaner, healthier worldenvironment for this and generations to come.

Do not use a booster battery or any other boostersource that has a greater than 12 Volt system, i.e.,do not use a 24 Volt power source.

NOTE: Replacement batteries should both be of equalsize to prevent damage to the vehicles charging system.

Do not connect the cable to the negative post of thedischarge battery. The resulting electrical spark

could cause the battery to explode. During cold weather when temperatures are be-
