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.

To fill the DEF tank, see an authorized dealer or do the following (before
filling the DEF tank in cold climates, seeFilling the DEF tank in cold
climateslater in this section):
DEF Bottle Fill with Spout
The following procedure applies to Motorcraft DEF or similar DEF
bottles. For other brands or bottle types, see the instructions on the
bottle label.
1. Remove the cap from the DEF
container and twist the spout onto
the container until the locking tab
engages.
2. Open the DEF filler port on your
vehicle by turning the blue cap
counterclockwise a quarter-turn.
3. Lift and hold the DEF container,
without tipping, and insert the
spout, into the DEF filler port.
4. Lift and tip the container to let
DEF flow into the tank. Pour DEF
until the container is empty or DEF
flow stops. DEF can be seen flowing
through the spout, but does not
completely fill the spout while
flowing. Air is trapped in the spout
while DEF is flowing. When the
DEF tank is full, DEF completely
fills the spout and displaces the air
in the spout.

Push the palm release lever (A) on
the parking brake handle (B) and
push down as far as possible to
release the brake. Driving with the
parking brake on causes the brakes
to wear out quickly and reduces
fuel economy.
We recommend you not use the parking brake to stop a moving vehicle.
However, if the normal brakes fail, you can use the parking brake to stop
your vehicle in an emergency. Since the parking brake only applies
retardation to the rear wheels, the vehicle’s stopping distance increases
greatly and the handling of your vehicle is adversely affected.
Power Park (Hydraulic Brake Vehicles Only)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, hydraulically released driveline parking brake.
The park brake dash-mounted, yellow knob-type switch controls the
Power Park Brake. The switch has three positions: apply (out), neutral
(central), and release (in). The switch is spring-loaded to return to the
neutral (central) position after pushing or pulling it.
There is no visual indication at the knob that the parking brake
is applied or released; check the instrument cluster. If the light
is illuminated, the parking brake is applied.
Applying the Parking Brake
Pull the yellow, dash-mounted parking brake knob. The parking brake
light illuminates indicating that the parking brake has been successfully
set.
Note:If the light blinks and a warning tone sounds when you pull the
control knob, the parking brake is not functioning properly. Seek
immediate service from your dealer. SeeParking brake warning
systemin this section.
Releasing the Parking Brake
WARNING:Hold the brake pedal down while moving the
gearshift lever from position to position. If the brake pedal is not
held down, the vehicle may move unexpectedly resulting in property
damage, personal injury or death.

If you install an electrical back up alarm, connect it to the backup lamp
circuit.
Parking
WARNING:When parking your vehicle, do not leave the
transmission in gear; if the key is in the on position and the
vehicle rolls, the engine could start. Failure to follow these instructions
could result in an unattended vehicle moving, possibly causing personal
injury or property damage.
Always use the parking brake. When parking on a grade, block the
wheels and turn the front wheels to one side so that if your vehicle rolls,
the front tires act against the curb to stop your vehicle. The front wheels
are more effective at stopping a rolling vehicle than the rear wheels.
Cold Weather
Note:Idling in cold weather does not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a build-up of heavy deposits of carbon and rust on valve stems causing
them to stick which, in turn, can cause valvetrain damage.
Note:We recommend against using winter fronts, or other air-restrictive
devices mounted in front of the radiator on vehicles with
chassis-mounted charge air coolers, unless extremely cold weather
conditions exist. Airflow restriction can cause high exhaust temperatures,
power loss, excessive fan usage and a reduction in fuel economy. If you
must use a winter front, the device should have a permanent opening of
at least 120 square inches (774 square centimeters) directly in line with
the fan hub.
For best engine operation in temperatures of 32°F (0°C) or lower:
•Make sure the batteries are the correct type and are fully charged.
Check other electrical components to make sure they are in optimum
condition.
•Use a permanent-type engine coolant to protect the engine against
damage from freezing.
•If your vehicle is equipped with a water-fuel separator, drain it daily.
Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Use the proper engine oil and maintain it at its proper level.

•At temperatures of –4°F (–20°C) or below, it is recommended that
you use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, air
conditioning condenser and accessories clean to avoid dirt build-up.
•You may experience above normal coolant temperatures while driving
in a transmission gear ratio that lugs the engine. To correct this
problem, increase engine speed by downshifting into the next lower
gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering your vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate your vehicle with the power steering pump fluid level
below the ADD mark on the MAX COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by an authorized dealer.
•Low power steering pump fluid levels may cause heavy or uneven
steering efforts. Check the power steering pump fluid level before
seeking service from an authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX HOT side of the power steering reservoir dipstick, as this
may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer your vehicle manually, but it takes more effort.

After first 500 and 1000 miles (800
and 1600 km), then every 500 and
1000 mile (800 and 1600 km)
interval after tire removal or
replacement.Tighten the wheel mounting nuts
