Ford 2014 Fusion Hybrid v.1 Manuel d'utilisateur télécharger pdf (Page 251)

Vehicles driven year-round in non-extreme

climates should use prediluted coolant

meeting the Ford specification for

optimum cooling system and engine

protection.

What You Should Know About Fail-

Safe Cooling

If the engine coolant supply is depleted,

this feature allows the vehicle to be driven

temporarily before incremental component

damage is incurred. The “fail-safe”

distance depends on ambient

temperatures, vehicle load and terrain.

How Fail-Safe Cooling Works

If the engine begins to overheat, the engine

coolant temperature gauge will move to

the red (hot) area and:

The coolant temperature

warning light will illuminate.

The service engine soon

indicator will illuminate.

If the engine reaches a preset

over-temperature condition, the engine

will automatically switch to alternating

cylinder operation. Each disabled cylinder

acts as an air pump and cools the engine.

When this occurs the vehicle will still

operate. However:

• The engine power will be limited.

• The air conditioning system will be

disabled.

Continued operation will increase the

engine temperature and the engine will

completely shut down, causing steering

and braking effort to increase.

Once the engine temperature cools, the

engine can be re-started. Take your vehicle

to an authorized dealer as soon as possible

to minimize engine damage.

When Fail-Safe Mode Is Activated

WARNINGS

Fail-safe mode is for use during

emergencies only. Operate the

vehicle in fail-safe mode only as long

as necessary to bring the vehicle to rest in

a safe location and seek immediate repairs.

When in fail-safe mode, the vehicle will

have limited power, will not be able to

maintain high-speed operation, and may

completely shut down without warning,

potentially losing engine power, power

steering assist, and power brake assist,

which may increase the possibility of a

crash resulting in serious injury.

Never remove the coolant reservoir

cap while the engine is running or hot.

Note: Driving the vehicle without repairing

the engine problem increases the chance of

engine damage. Take your vehicle to an

authorized dealer as soon as possible.

You have limited engine power when in the

fail-safe mode, so drive the vehicle with

caution. The vehicle will not be able to

maintain high-speed operation and the

engine will run rough. Remember that the

engine is capable of completely shutting

down automatically to prevent engine

damage, therefore:

1. Pull off the road as soon as safely

possible and turn off the engine.

2. Arrange for the vehicle to be taken to

an authorized dealer.

3. If this is not possible, wait a short

period for the engine to cool.

4. Check the coolant level and replenish

if low.

5. Re-start the engine and take your

vehicle to an authorized dealer.
