2018 FORD F-150 check engine

During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator lights when
the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See Fuel Quality (page 184).
Allowing water to stay in the fuel system,
after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.
Note: Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.

STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases. This helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer.
Note: You can crank the engine for a total
of 60 seconds (without the engine starting)
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each
time, without the engine starting, you
reached the 60-second time limit. A
message appears in the information display
alerting you that you exceeded the cranking
time. You cannot attempt to start the
engine for at least 15 minutes. After 15
minutes, you are limited to a 15-second
engine cranking time. You need to wait 60
minutes before you can crank the engine for
60 seconds again.
Before starting the engine, check the
following:
• Make sure all occupants have fastened
their seatbelts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on. •
Move the transmission selector lever
to position P.
• Turn the ignition key to on. If your
vehicle is equipped with a keyless
ignition, see the following instructions.
Vehicles with an Ignition Key
Note: Do not touch the accelerator pedal.
1. Fully depress the brake pedal.
2. Turn the key to start the engine. Release the key when the engine starts.
Note: The engine may continue cranking
for up to 15 seconds or until it starts.
Note: If you cannot start the engine on the
first try, wait for a short period and try again.
Vehicles with Keyless Start
Note: Do not touch the accelerator pedal.
Note: You must have your intelligent access
key in the vehicle in order to shift the
transmission out of position
P.
1. Fully depress the brake pedal.
2. Press the button.
The system does not function if:
• The key frequencies are jammed.
• The key battery has no charge.
If you are unable to start the engine, locate
the backup slot (A) in one of two positions:

Guarding Against Exhaust Fumes WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Important Ventilating Information
If you stop your vehicle and leave the
engine idling for long periods, we
recommend that you do one of the
following:
• Open the windows at least
1 in
(2.5 cm).
• Set your climate control to outside air.
STARTING A DIESEL 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 to
Engine oil specifications for more
information. See
Capacities and
Specifications (page 424).
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 your vehicle. A message will
appear in the information display as your
vehicle warms up. 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 and a
message will appear informing you the
vehicle is ok to drive.
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.
Before starting the engine check the
following:
• Make sure all occupants have fastened
their seatbelts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P).
Note: Do not press the accelerator during
starting.
Vehicles with Keyless Start
Note: Do not touch the accelerator pedal.
