Ford 2014 F-550 v.3 Manuel d'utilisateur télécharger pdf (Page 139)

We recommend regular unleaded gasoline

with a pump (R+M)/2 octane rating of 87.

Some stations offer fuels posted as regular

with an octane rating below 87, particularly

in high altitude areas. We do not

recommend fuels with an octane rating

below 87.

Do not be concerned if your engine

sometimes knocks lightly. However, if it

knocks heavily under most driving

conditions while you are using fuel with the

recommended octane rating, see your

authorized dealer to prevent any engine

damage.

RUNNING OUT OF FUEL

Avoid running out of fuel because this

situation may have an adverse effect on

powertrain components.

If you have run out of fuel:

• You may need to cycle the ignition from

off to on several times after refueling

to allow the fuel system to pump the

fuel from the tank to the engine. On

restarting, cranking time will take a few

seconds longer than normal. With

keyless ignition, just start the engine.

Crank time will be longer than usual.

• Normally, adding 1 gallon (3.8 liters) of

fuel is enough to restart the engine. If

the vehicle is out of fuel and on a steep

grade, more than 1 gallon (3.8 liters)

may be required.

• The service engine soon indicator may

come on. For more information on the

service engine soon indicator, See

Warning Lamps and Indicators

(page 77).

Refilling With a Portable Fuel

Container

WARNINGS

The fuel system may be under

pressure. If the fuel filler cap is

venting vapor or if you hear a hissing

sound, wait until it stops before completely

removing the fuel filler cap. Otherwise, fuel

may spray out and cause personal injury.

Do not try to pry open or push open

the fuel system with foreign objects.

This could damage the fuel system

and its seal and cause personal injury to

you or others.

Use the following directions when filling

from a portable fuel container:

1. Remove the fuel cap from the fuel filler

pipe by rotating it counter clockwise.

2. Slowly insert the portable fuel

container into the fuel filler opening.

3. Fill the vehicle with fuel from the

portable fuel container.

4. 4. When done, remove the portable

fuel container nozzle and reinstall fuel

cap. Insert fuel cap into fuel filler

opening and turn clockwise until a click

is heard.

REFUELING

WARNINGS

Fuel vapor burns violently and a fuel

fire can cause severe injuries.

Read and follow all the instructions

on the pump island.

Turn off your engine when you are

refueling.

Do not smoke if you are near fuel or

refueling your vehicle.
