STARTING THE ENGINE
Read all starting instructions carefully before you start your vehicle.
For temperatures below 32°F (0°C), the use of the correct grade engine
oil is essential for proper operation. Refer toEngine oil specifications
in theMaintenancechapter for more information.
Your vehicle may be equipped with a cold weather starting strategy that
prevents severe engine damage by assisting in engine lubrication
warm-up. In extremely cold ambient temperatures, this strategy activates
and prevents the accelerator pedal from being used for 30 seconds after
starting the vehicle. By not allowing the accelerator pedal to be used, the
engine oil is allowed to properly lubricate the bearings preventing engine
damage due to lack of proper lubrication. After the 30 second warm-up
period, the accelerator pedal will be operational again as long as the
pedal is not being pressed when the 30 second time limit expires. When
starting the engine in extremely cold temperatures (-15°F [–26°C]), it is
recommended to allow the engine to idle for several minutes before
driving the vehicle.
Make sure the gearshift lever is in P (Park) and the parking brake is fully
set before you turn the key. Do not press the accelerator during starting.
Cold Weather Starting
WARNING:Do not use starting fluid, such as ether, in the air
intake system (see air filter decal). Such fluid could cause
immediate explosive damage to the engine and possible personal injury.
WARNING:Do not add gasoline, gasohol or alcohol to diesel
fuel. This practice creates a serious fire hazard and causes
engine performance problems.
It is recommended that the engine block heater be used for starting
when the temperature is -10°F (-23°C) or colder. Refer toEngine block
heater (if equipped)in theStarting and Stopping the Enginechapter
of yourOwner’s Manual.
When operating in cold weather, Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from a reputable manufacturer may
be used as needed.

OCR precautions and safe exhaust position
WARNING:Failure to comply with the following instructions for
operator commanded regeneration (OCR) may result in fire,
serious injury, death and/or property damage.
Before you start OCR, observe/do the following:
•Place the vehicle in P (Park) with the parking brake set on stable,
level ground.
•The vehicle must not be parked in a structure.
•The vehicle must be 10 – 15 feet (3 – 5 meters) away from any
obstructions,
•and must be away from materials that can easily combust or melt such
as: paper, leaves, petroleum products, fuels, plastics and other dry
organic material, such as grass.
•Make sure there is a minimum of 1/8 tank of fuel.
•Make sure all fluids are at proper levels.
Make sure that the louvers (holes) located at the tip of the exhaust are
also clear of any obstructions as they are used to introduce fresh air into
the tailpipe to cool the exhaust gas as it leaves. SeeExhaustunder the
Cleaningchapter for more information.
How to start operator commanded regeneration (OCR)
WARNING:Stay clear of exhaust tip during regeneration. You or
others can be burned.
Note:OCR will not be allowed until DPF load percentage has reached
100% (Full). The DPF load percentage will fluctuate up and down when
driving your vehicle due to active and passive regenerations.
Note:During the use of OCR, you may observe a light amount of white
smoke. This is normal.
OCR will not be allowed to operate
if the service engine soon light is
illuminated

Multi-point Inspection
In order to keep your vehicle running right, it is important to have the
systems on your vehicle checked regularly. This can help identify
potential issues and prevent major problems. Ford Motor Company
recommends the following multi-point inspection be performed at every
scheduled maintenance interval to help make sure your vehicle keeps
running great.
Multi-point Inspection
Accessory drive belt(s) Horn operation
Battery performance Radiator, cooler, heater and A/C hoses
Engine air filter Suspension component for leaks or
damage
Exhaust system Steering and linkage
Exterior lamps and hazard
warning system operationTires (including spare) for wear and
proper pressure
**
Fluid levels*; fill if necessary Windshield for cracks, chips or pits
For oil and fluid leaks Washer spray and wiper operation
*Brake, coolant recovery reservoir, automatic transmission, power
steering and window washer.
**If your vehicle is equipped with a temporary mobility kit, check the tire
sealant expiration Use By date on the canister. Replace as needed.
Be sure to ask your dealership service advisor or technician about the
multi-point vehicle inspection. It is a comprehensive way to perform a
thorough inspection of your vehicle. It is your checklist that gives you
immediate feedback on the overall condition of your vehicle. You will
know what has been checked, what is okay, as well as those things that
may require future or immediate attention. The multi-point vehicle
inspection is one more way to keep your vehicle running great!
