Engine coolant
temperature gauge:
Indicates engine
coolant temperature. At
normal operating temperature, the needle will be in
the normal range (between“H”and“C”). If it enters
the red section, the engine is overheating. Stop the
vehicle as soon as safely possible, switch off the
engine and let the engine cool.
Never remove the coolant reservoir cap
while the engine is running or hot.
Odometer:Registers
the total kilometers
(miles) of the vehicle.
Trip odometer:
Registers the
kilometers (miles) of
individual journeys.
Press and release the
reset button until a“T”
appears in the display.
Press and hold the button for three seconds to reset.

Do not rock the vehicle for more than a minute
or damage to the transmission and tires may
occur, or the engine may overheat.
MANUAL TRANSMISSION OPERATION
(IF EQUIPPED)
Using the clutch
The manual transmission has a starter interlock that
prevents cranking the engine unless the clutch pedal
is fully depressed.
To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the floor, then put the
gearshift lever in the neutral position.
3. Start the engine, then press the brake pedal and
release the parking brake.
4. Move the gearshift lever to the desired gear, then
slowly release the clutch pedal while slowly pressing
on the accelerator.
During each shift, the clutch pedal must be fully
depressed to the floor. Failure to fully depress the
clutch pedal to the floor may cause increased shift
efforts and prematurely wear components in the
transmission. Make sure the floor mat is properly
positioned so it doesn’t interfere with the full
extension of the clutch pedal.
Do not drive with your foot resting on the clutch
pedal or use the clutch pedal to hold your vehicle at

Mixing Motorcraft Speciality Orange Engine Coolant
or any orange-colored extended life product with
your factory filled coolant can result in degraded
corrosion protection.
•A large amount of water without engine coolant
may be added, in case of emergency, to reach a
vehicle service location. In this instance, the
cooling system must be drained and refilled with a
50/50 mixture of engine coolant and distilled
water as soon as possible. Water alone (without
engine coolant) can cause engine damage from
corrosion, overheating or freezing.
•Do not use alcohol, methanol or brine or any
engine coolants mixed with alcohol or
methanol antifreeze (coolant).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
engine coolant.
To reduce the risk of personal injury, make
sure the engine is cool before unscrewing
the coolant pressure relief cap. The cooling system
is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
If you must remove the pressure relief cap or
radiator cap (depending upon engine application),
follow these steps to avoid personal injury:
1. Before you remove the cap, turn the engine off
and let it cool.
2. When the engine is cool, wrap a thick cloth
around the cap. Slowly turn cap counterclockwise
until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been
released, use the cloth to turn it counterclockwise
and remove the cap.

If the concentration is not 50/50 (protection to
–34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and
additions to obtain a 50/50 coolant concentration.
Whenever coolant has been added, the coolant level
in the coolant reservoir should be checked the next
few times you drive the vehicle. If necessary, add
enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper
level.
If you have to add more than 1.0 liter (1.0 quart) of
engine coolant per month, have your dealer check
the engine cooling system. Your cooling system may
have a leak. Operating an engine with a low level of
coolant can result in engine overheating and possible
engine damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use
of recycled engine coolant in vehicles originally
equipped with Motorcraft Premium Gold Engine
Coolant since a Ford-approved recycling process is
not yet available.
Used engine coolant should be disposed of in
an appropriate manner. Follow your community’s
regulations and standards for recycling and disposing
of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling
system can hold, refer toRefill capacitiesin this
chapter.
Fill your engine coolant reservoir as outlined in
Adding engine coolantin this chapter.
Severe climates
If you drive in extremely cold climates (less than
–36°C[–34°F]):
•It may be necessary to increase the coolant
concentration above 50%.

•NEVER increase the coolant concentration
above 60%.
•Increased engine coolant concentrations
above 60% will decrease the overheat
protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container
to ensure the coolant concentration in your
vehicle will provide adequate freeze
protection at the temperatures in which you
drive in the winter months.
If you drive in extremely hot climates:
•It is still necessary to maintain the coolant
concentration above 40%.
•NEVER decrease the coolant concentration
below 40%.
•Decreased engine coolant concentrations
below 40% will decrease the corrosion
protection characteristics of the engine
coolant and may cause engine damage.
•Decreased engine coolant concentrations
below 40% will decrease the freeze
protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container
to ensure the coolant concentration in your
vehicle will provide adequate protection at
the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates
should use a 50/50 mixture of engine coolant and
distilled water for optimum cooling system and
engine protection.
