F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Introduction

We recommend the use of Top Tier Diesel
fuel where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance. Look for
the Top Tier logo at the station. For
additional information, visit
www
.t op tier g a s. c om .
Note: The vehicle Warranty does not cover
damage caused by using an improper type
of fuel or fuel additive.
Note: Do not blend used engine oil with
diesel fuel under any circumstances.
Blending used oil with the fuel significantly
increases exhaust emissions and reduces
engine life due to increased internal wear. Using low sulfur diesel fuel with
16-500 ppm or high sulfur diesel
fuel with greater than 500 ppm
in your diesel engine will cause certain
emission components to malfunction,
which could also cause the service engine
soon light to illuminate, indicating an
emissions-related concern.
Diesel fuel is adjusted seasonally for cold
temperature. For best results at
temperatures below 19°F (-7°C), it is
recommended to use a diesel fuel which
has been seasonally adjusted for the
ambient conditions.
Fuel Requirements - Choosing The
Right Fuel: Vehicles Operated
Where Ultra Low Sulfur Diesel Fuel
Is Not Required
For the engine to operate reliably on
low-sulfur or high-sulfur diesel fuel, the
engine must be a factory built high-sulfur
engine, available as a dealer order option
for select markets, or an ultra low sulfur
diesel fuel configured engine that has been
retrofitted for high-sulfur diesel fuel using
authorized dealer service parts. Failure to use retrofit components other than those
available through your authorized dealer
will result in coolant system damage,
engine overheating, selective catalyst
reduction system or diesel particulate filter
damage and possible base engine damage.
Use only a diesel engine configured for use
with high sulfur diesel fuel in markets with
diesel fuel that has sulfur content greater
than 15 ppm. Using low sulfur diesel fuel
with 16–500 ppm or high sulfur diesel fuel
with greater than 500 ppm in a diesel
engine requiring only Ultra Low Sulfur
Diesel fuel could result in damage to
engine emission control devices and the
aftertreatment system, potentially
rendering the vehicle inoperable.
Vehicles with engines configured for use
with high sulfur diesel fuel are only
available for sale in countries where ultra
low sulfur diesel fuel is generally not
available or mandated by the government.
Vehicles originally sold in a ultra low sulfur
diesel fuel market that are subsequently
exported to non- ultra low sulfur diesel fuel
markets will need to be retrofitted at the
customer
’s expense using authorized
dealer service parts in order to be reliably
operated on non- ultra low sulfur diesel
fuel.
Biodiesel WARNING:
Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.

F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Fuel and Refueling

Filling the Fuel Tank
For consistent results when refueling:
•
Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate
(low-medium-high) each time the tank
is filled.
• Allow no more than one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1,000 mi (1,600 km) of driving (this is
your engine ’s break-in period). A more
accurate measurement is obtained after
2,000 mi (3,200 km)
to 3,000 mi
(4,800 km). Also, fuel expense, frequency
of fill ups or fuel gauge readings are not
accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the fuel tank, record the amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per
gallon) fuel consumption, divide miles
traveled by gallons used. 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. Keeping records during
summer and winter will show how
temperature impacts fuel economy.
Conditions
•
Heavily loading your vehicle reduces
fuel economy.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.

Servicing a Vehicle with an
Electronic Locking Differential
Turn the engine off and raise all drive
wheels of the locker differential axle to
prevent your vehicle from moving when
servicing the wheels, tires or brakes. Axles
equipped with a driver-controlled
differential deliver power to both wheels
even when only one wheel is on the ground.
WARNING: Failure to raise all drive
wheels with this type of differential could
cause the vehicle to move unexpectedly,
resulting in property damage, personal
injury or death.
2-SPEED REAR AXLE (IF EQUIPPED) WARNING: Never shift a
two-speed axle when descending a
steep grade as this may cause loss of
vehicle control and result in personal
injury.
Note: Do not shift between ranges when
the speed control is on.
A two-speed rear axle allows the driver to
select a low range for greater pulling power
and a high range for greater road speed
and fuel economy. You can also use these
ranges to provide extra steps between
transmission shifts when driving on steep
grades or fuel economy may be factors. Axle Shifting Note:
Do not shift the axle to LOW when
your vehicle is moving. Use LOW when you
drive a fully loaded vehicle on a severe grade
or in congested traffic. Use HIGH for all
normal driving conditions with a lightly
loaded or partially loaded vehicle.
Note: The axle is set to HIGH by default.
To shift the axle between HIGH and LOW
with the vehicle stopped, place the
transmission in position N, then press and
hold the button for two seconds.

There are three types of maintenance
intervals for general vehicle environments:
On-Highway, City and Severe Service. In
all applications, monitoring miles
(kilometers) and time and when the engine
is due for an oil change determine the
actual interval. When the engine oil change
is required before the truck lubrication
interval, perform the lubrication at the
same time in order to reduce your vehicle
’s
time out of service.
Air Brake Adjustment WARNING: Failure to maintain
proper air brake adjustment can result
in reduction or loss of braking ability.
A qualified service technician, keeping to
the instructions in the service manual,
should perform air brake inspection and
adjustment or repairs.
Cam Brakes - Automatic Slack
Adjusters WARNING: Do not manually adjust
the automatic slack adjusters to correct
excessive push rod stroke as it may result
in reduced brake effectiveness and a
vehicle crash. Excessive push rod stroke
indicates that a problem exists with the automatic adjuster, with the installation
of the adjuster, or with foundation brake
components that manual adjustment
does not remedy. Seek service from a
qualified facility for excessive push rod
stroke.
Inspect standard air brakes equipped with
automatic slack adjusters for proper brake
adjustment as listed in the maintenance
schedule charts.
However, inspect the brakes more
frequently when subjecting them to heavy
use or adverse operating conditions such
as:
• Frequent brake applications while fully
loaded.
• Operation on hilly or mountainous
terrain.
• Frequent operation on dirt, gravel or
mud.
Some aftermarket brake linings also
require more frequent inspections.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check Every Month
