Trailer
If you are pulling a trailer, perform an inspection of the trailer similar to
that of the tractor. The inspection should follow trailer manufacturer
recommendations and should include at a minimum: general condition,
landing gear, doors, sides, lights, reflectors, suspension, brakes, tires,
wheels, cargo placement, stability and tie-downs.
Transmission
WARNING:If the unit starts in gear and/or the neutral start
switch is not functioning correctly, the vehicle may inadvertently
move which could result in property damage, personal injury or death.
If your vehicle is equipped with an automatic transmission, regularly
inspect the transmission’s neutral start switch. The engine should only
start in positionNorP.
Inspect the transmission fluid level and shift linkage for proper
operation.

HEATED SEATS (IF EQUIPPED)
WARNING:Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes, spinal cord
injury, medication, alcohol use, exhaustion, or other physical conditions,
must exercise care when using the seat heater. The seat heater may
cause burns even at low temperatures, especially if used for long
periods of time. Do not place anything on the seat that insulates against
heat, such as a blanket or cushion, because this may cause the seat
heater to overheat. Do not puncture the seat with pins, needles, or
other pointed objects because this may damage the heating element
which may cause the seat heater to overheat. An overheated seat may
cause serious personal injury.
Note:Do not do the following:
•Place heavy objects on the seat.
•Operate the seat heater if water or any other liquid is spilled on the
seat. Allow the seat to dry thoroughly.
•Operate the heated seats unless the engine is running. Doing so could
drain your vehicle’s battery.
Press to cycle through the various heat settings and off.
Warmer settings are indicated by more indicator lights.

IGNITION SWITCH
Note:When you switch the ignition off and leave your vehicle, do not
leave your key in the ignition. This could discharge your vehicle battery.
A.Accessory:Allows the electrical accessories, such as the radio, to
operate while the engine is not running.
B.Lock:Locks the automatic transmission gearshift lever, if equipped
with positionP,and allows key removal.
C.Off:Shuts off the engine and all accessories.
D.On:All electrical circuits are operational. Warning lights are
illuminated. Key position when driving.
E.Start:Cranks the engine. Release the key as soon as the engine
starts.
STARTING A GASOLINE ENGINE
When the engine starts, the idle RPM runs faster to warm the engine. If
the engine idle speed does not slow down automatically, have your
vehicle checked.
Before starting your vehicle:
•Make sure all occupants buckle their safety belts.
•Make sure the headlamps and electrical accessories are off.
•Make sure the parking brake is set.
•Make sure the gearshift is in positionP.
•Turn the key to on without turning the key to start.
Some warning lights briefly illuminate.
Note:Do not touch the accelerator pedal.

Owners Guide gf(ownloose), 1st Printing, December 2013

Keep a record for at least one month and record the type of driving (city
or highway). This provides an accurate estimate of your vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter shows how temperature impacts fuel
economy. In general, lower temperatures mean lower fuel economy.
SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM (DIESEL
ENGINE ONLY)
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of Maintaining the DEF Level
In order for the SCR system to operate properly, you must maintain the
DEF level. Generally, you should fill the DEF tank before the DEF gauge
in the instrument cluster reaches the first low level warning (see
Warning messages and vehicle operations).
The engine control unit monitors the amount of fluid available in the
DEF tank. Failure to maintain an adequate amount of DEF in the system
generates warning messages that appear in the information display and,
unless you refill the DEF tank, leads to a forced reduction of engine
operations.
Warning Messages and Vehicle Operations
The instrument cluster contains a DEF gauge and indicator lights to alert
you to any low DEF level conditions. The indicator lights illuminate if the
DEF gauge level drops below 1 gallon (3.8 liters) in the 5-gallon
(19.0 liters) DEF tank or 2 gallons (7.6 liters) in the 10-gallon
(34.0 liters) DEF tank.
Upon filling the DEF tank after a low-level warning, normal operation
resumes when you restart your vehicle.

Safety Chains
Note:Do not attach safety chains to the bumper.
Always connect the trailer’s safety chains to the frame or hook retainers
of your vehicle hitch.
To connect the trailer’s safety chains, cross the chains under the trailer
tongue and allow enough slack for turning tight corners. Do not allow the
chains to drag on the ground.
Trailer Brakes
WARNING:Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not have
enough braking power and your chances of having a crash greatly
increase.
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if you install them properly and adjust them to the manufacturer’s
specifications. The trailer brakes must meet local and federal regulations.
The rating for the tow vehicle’s braking system operation is at
the gross vehicle weight rating, not the gross combined weight
rating.
Trailer Lamps
WARNING:Never connect any trailer lamp wiring to the
vehicle’s tail lamp wiring; this may damage the electrical system
resulting in a fire. Contact an authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing up to get the feel of your
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels clear curbs and other obstacles.
When Towing a Trailer
•Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).

4. Make sure the coupler release lever is in the locked position.
5. Charge the trailer brake system. Set the trailer brakes, with either
the hand valve or tractor protection valve. Pull against the trailer for
an extra check of proper hook-up. Do not pull hard enough to
damage or strain the equipment.
6. Set the tractor parking brakes and fully raise the trailer landing gear.
See theBrakeschapter for proper operation of the parking brake
and trailer brakes.
7. Check the operation of all trailer lights and correct any lights that
may be faulty.
Un-hook
1. Try to keep the tractor and trailer in a straight line.
2. Apply the parking brakes.
3. Lower the trailer landing gear, making sure it is on solid, level
ground. The weight of the trailer is to be on the landing gear.
4. Block the trailer wheels.
5. Disconnect the brake hoses and light cords. Be sure hoses and cords
are clear.
6. Pull coupler release lever to disengage the fifth wheel jaws.
7. Release the tractor parking brakes.
8. Pull out from the trailer slowly, allowing the landing gear to take the
load gradually.
WRECKER TOWING
WARNING:To reduce the risk of personal injury or property
damage when manually releasing the spring brakes, be sure to
block the wheels so the vehicle cannot move once the brakes are
released.
Note:Make sure to connect your vehicle securely to the tow vehicle and
that the tow vehicle’s parking brakes are set before releasing the disabled
vehicle’s spring brakes.
Before moving the disabled vehicle, check for adequate road clearance of
vehicle components. If possible, unload the disabled vehicle before
towing. This reduces any abnormal load to the vehicle components
resulting from the towing procedures. Before towing, make sure to
release the parking brake fully. You can reset the spring-actuated type
parking brake by recharging the air system with at least 64 psi (441 kPa)
of air. If the brake system does not retain air pressure, then you must
release the spring brakes manually. SeeParking brakein theBrakes
chapter.
