Maintain coolant concentration within

It is very important to use prediluted

coolant approved to the correct

48% to 50%, which equates to a freeze

point between -34°C (-29°F) and -37°C

checked using a refractometer. We do not

recommend the use of hydrometers or

coolant test strips for measuring coolant

concentration.

specification in order to avoid plugging the

small passageways in the engine cooling

system. See Capacities and

Specifications (page 485). Do not mix

different colors or types of coolant in your

vehicle. Mixing of engine coolants or using

an incorrect coolant may harm the engine

or cooling system components and may

not be covered by the vehicle Warranty.

Adding Coolant

Note: If prediluted coolant is not available,

use the approved concentrated coolant

diluting it to 50/50 with distilled water. See

Capacities and Specifications (page 485).

Using water that has not been deionised

may contribute to deposit formation,

corrosion and plugging of the small cooling

system passageways.

Note: Coolants marketed for all makes and

models may not be approved to our

specifications and may cause damage to

the cooling system. Resulting component

damage may not be covered by the vehicle

Warranty.

WARNING: Do not add engine

coolant when the engine is on or the

cooling system is hot. Failure to follow

this instruction could result in personal

injury.

WARNING: Do not remove the

coolant reservoir cap when the engine is

on or the cooling system is hot. Wait 10

minutes for the cooling system to cool

down. Cover the coolant reservoir cap

with a thick cloth to prevent the

possibility of scalding and slowly remove

the cap. Failure to follow this instruction

could result in personal injury.

If the coolant level is at or below the

minimum mark, add prediluted coolant

immediately.

WARNING: Do not put coolant in

the windshield washer reservoir. If

sprayed on the windshield, coolant could

make it difficult to see through the

windshield.

To top up the coolant level do the

following:

1. Unscrew the cap slowly. Any pressure

escapes as you unscrew the cap.

2. Add prediluted coolant approved to

the correct specification. See

Capacities and Specifications (page

485).

Note: Do not use stop leak pellets, cooling

system sealants, or non-specified additives

as they can cause damage to the engine

cooling or heating systems. Resulting

component damage may not be covered by

prediluted engine coolant to bring the

coolant level to the correct level.

Severe Climates

If you have to add more than 1 L (1.1 qt) of

engine coolant per month, have your

vehicle checked as soon as possible.

Operating an engine with a low level of

coolant can result in engine overheating

and possible engine damage.

In case of emergency, you can add a large

amount of water without engine coolant

in order to reach a vehicle service location.

In this instance, qualified personnel:

If you drive in extremely cold climates:

•

It may be necessary to increase the

coolant concentration above 50%.

Coolant concentrations below 40%

decrease the overheat and corrosion

protection characteristics of the

coolant and may cause engine

damage.

Do not use the following as a coolant

substitute:

•

Alcohol.

Methanol.

Brine.

Vehicles driven year-round in non-extreme

climates should use prediluted coolant for

optimum cooling system and engine

protection.

Any coolant mixed with alcohol or

methanol antifreeze.

Coolant Change

Alcohol and other liquids can cause engine

damage from overheating or freezing.

Do not add extra inhibitors or additives to

the coolant. These can be harmful and

compromise the corrosion protection of

the coolant.

At specific mileage intervals, as listed in

the scheduled maintenance information,

the coolant should be changed. Add

prediluted coolant approved to the correct

specification. See Capacities and

Specifications (page 485).

Recycled Coolant

We do not recommend the use of recycled

coolant as an approved recycling process

is not yet available.

Note: Dispose of used coolant in the

appropriate manner.

2. Leave the engine running until the

coolant temperature gauge needle

returns to the normal position. If the

temperature does not drop after

several minutes, follow the remaining

steps.

WARNING: To reduce the risk of

crash and injury, be prepared that the

vehicle speed may reduce and the

vehicle may not be able to accelerate

with full power until the coolant

temperature reduces.

3. Switch the engine off and wait for it to

cool. Check the coolant level.

If you tow a trailer with your vehicle, the

engine may temporarily reach a higher

temperature during severe operating

conditions, for example ascending a long

temperatures.

4. If the coolant level is at or below the

minimum mark, add prediluted coolant

immediately.

5. If the coolant level is normal, restart

the engine and continue.

At this time, you may notice the coolant

temperature gauge moves toward the red

zone and a message may appear in the

information display.

BRAKE FLUID CHECK

You may notice a reduction in vehicle

speed caused by reduced engine power in

order to manage the engine coolant

temperature. Your vehicle may enter this

mode if certain high-temperature and

high-load conditions take place. The

amount of speed reduction depends on

vehicle loading, grade and ambient

temperature. If this occurs, there is no

need to stop your vehicle. You can

continue to drive.

The air conditioning may automatically

turn on and off during severe operating

conditions to protect the engine from

overheating. When the coolant

temperature decreases to the normal

operating temperature, the air conditioning

turns on.

WARNING: Do not use any fluid

other than the recommended brake fluid

as this will reduce brake efficiency. Use

of incorrect fluid could result in the loss

of vehicle control, serious personal injury

or death.

WARNING: Only use brake fluid

from a sealed container. Contamination

with dirt, water, petroleum products or

other materials may result in brake

system damage or failure. Failure to

adhere to this warning could result in the

loss of vehicle control, serious personal

injury or death.

WARNING: Do not allow the fluid

to touch your skin or eyes. If this

happens, rinse the affected areas

immediately with plenty of water and

contact your physician.

If the coolant temperature gauge moves

fully into the red zone, or if the coolant

CHANGING THE 12V BATTERY

WARNING: A fluid level between

the MAX and MIN lines is within the

normal operating range and there is no

need to add fluid. A fluid level not in the

normal operating range could

compromise the performance of the

system. Have your vehicle checked

immediately.

WARNING: Batteries normally

produce explosive gases which can

cause personal injury. Therefore, do not

allow flames, sparks or lighted

substances to come near the battery.

When working near the battery, always

shield your face and protect your eyes.

Always provide correct ventilation.

WARNING: When lifting a

plastic-cased battery, excessive pressure

on the end walls could cause acid to flow

through the vent caps, resulting in

personal injury and damage to the

vehicle or battery. Lift the battery with a

battery carrier or with your hands on

opposite corners.

WARNING: Keep batteries out of

reach of children. Batteries contain

sulfuric acid. Avoid contact with skin,

eyes or clothing. Shield your eyes when

working near the battery to protect

against possible splashing of acid

solution. In case of acid contact with skin

or eyes, flush immediately with water for

a minimum of 15 minutes and get prompt

medical attention. If acid is swallowed,

call a physician immediately.

E170684

To avoid fluid contamination, the reservoir

cap must remain in place and fully tight,

unless you are adding fluid.

Only use fluid that meets Ford

specifications. See Capacities and

Specifications (page 476).

WARNING: Battery posts,

terminals and related accessories

contain lead and lead compounds. Wash

hands after handling.

battery. It does not require additional

water during service.

If the vehicle battery has a cover, make

sure you correctly install it after cleaning

or replacing the battery.

For longer, trouble-free operation, keep the

top of the battery clean and dry and the

battery cables tightly fastened to the

battery terminals. If any corrosion is

present on the battery or terminals, remove

the cables from the terminals and clean

with a wire brush. You can neutralize the

acid with a solution of baking soda and

water.

We recommend that you disconnect the

negative battery cable terminal from the

battery if you plan to store your vehicle for

an extended period.

Note: If you only disconnect the negative

battery cable terminal, make sure it is

isolated or placed away from the battery

terminal to avoid unintended connection or

arcing.

To maintain correct operation of the

battery management system, if you add

any electrical devices to your vehicle, do

not connect the ground connection directly

to the negative battery terminal. A

connection at the negative battery terminal

can cause inaccurate measurements of

the battery condition and potential

incorrect system operation.

Remove and Reinstall the Battery

To disconnect or remove the battery, do

the following:

1. Apply the parking brake and switch the

ignition off.

2. Switch all electrical equipment off, for

example lights and radio.

3. Wait a minimum of two minutes before

disconnecting the battery.

Note: The engine management system has

a power hold function and remains powered

for a period of time after you switch the

ignition off. This is to allow diagnostic and

adaptive tables to be stored. Disconnecting

the battery without waiting can cause

damage not covered by the vehicle

Warranty.

4. Disconnect the negative battery cable

terminal.

5. Disconnect the positive battery cable

terminal.

6. Remove the battery securing clamp.

7. Remove the battery.

Note: If you add electrical accessories or

components to your vehicle this may

adversely affect battery performance,

durability and the performance of other

electrical systems on your vehicle.

If you replace the battery make sure it

matches the electrical requirements of

your vehicle.

8. To install, reverse the removal

procedure.

Note: Before reconnecting the battery,

make sure the ignition remains switched off.

Note: Make sure the battery cable terminals

are fully tightened.
