•Optional instrument cluster
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, refer toWhat you
should know about fail-safe
coolingin theMaintenance and specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot.
Odometer:Registers the total miles (kilometers) of the vehicle.

MANUAL HEATING AND AIR CONDITIONING SYSTEM
(IF EQUIPPED)
1.Fan speed adjustment:Controls
the volume of air circulated in the
vehicle.
2.Temperature selection:
Controls the temperature of the
airflow in the vehicle.
3.Air flow selections:Controls the direction of the airflow in the
vehicle. See the following for a brief description on each control.
MAX A/C:Uses recirculated air to cool the vehicle. Air flows from the
instrument panel vents only. This mode will help prevent unpleasant
odors from entering the vehicle.
NORM A/C:Uses outside air to cool the vehicle. Air flows from the
instrument panel vents only.
VENT: Distributes outside air through the instrument panel vents.
OFF: Outside air is shut out and the fan will not operate.
FLOOR: Distributes outside air through the floor vents.
MIX: Distributes outside air through the windshield defroster vents, floor
vents and side window demisters.
:Distributes outside air through the windshield defroster vents and
the side window demisters.
Operating tips
•To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•To reduce humidity build up inside the vehicle: do not drive with the
air flow selector in the OFF or MAX A/C position.
•Under normal weather conditions, do not leave the air flow selector in
MAX A/C or OFF when the vehicle is parked. This allows the vehicle
to “breathe” using the outside air inlet vents.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.

If the indicator light(s) underneath the house icon blink rapidly for two
seconds and then turn to a continuous light, proceed with steps 6
through 8 to complete programming of a rolling code equipped device.
6. At the garage door opener receiver (motor-head unit) in the garage,
locate the “learn” or “smart” button (usually near where the hanging
antenna wire is attached to the unit).
7. Press and release the “learn” or “smart” button. (The name and color
of the button may vary by manufacturer.)
Note:There are 30 seconds in which to initiate step eight.
8. Return to the vehicle and firmly press, hold for two seconds and
release the HomeLinkbutton. Repeat the press/hold/release sequence
again, and, depending on the brand of the garage door opener (or other
rolling code equipped device), repeat this sequence a third time to
complete the programming.
HomeLinkshould now activate your rolling code equipped device. To
program additional HomeLinkbuttons begin with step 2 in the
“Programming” section. For questions or comments, please contact
HomeLink atwww.homelink.comor1–800–355–3515.
Gate operator & Canadian programming
During programming, your hand-held transmitter may automatically stop
transmitting — not allowing enough time for HomeLinkto accept the
signal from the hand-held transmitter.
After completing steps 1 and 2 outlined in the “Programming” section,
replace step 3 with the following:
Note:If programming a garage door opener or gate operator, it is
advised to unplug the device during the “cycling” process to prevent
overheating.
•Continue to press and hold the
HomeLinkbutton (note step 3
in the “Programming” section)
while you press and release —
every two seconds(“cycle”)
your hand-held transmitter until
the frequency signal has been
accepted by the HomeLink. The
message CHANNEL “X” (1,2 or 3)
TRAINING will appear on the
display.
•Proceed with step 4 in the “Programming” section.

To adjust the front seatback using
the manual recliner:
•Lift and hold the handle located
on the side of the seat.
•Lean against the seatback to
adjust it to your desired position.
You can recline the seat back or
bring it forward.
•Release the handle when the desired position has been reached.
Using the power lumbar support (if equipped)
The power lumbar control is located
on the outboard side of the seat.
Press one side of the control to
adjust firmness.
Press the other side of the control to adjust softness.
Heated seats (if equipped)
To operate the heated seats:
•Push the indicated side of the
control for maximum heat.
•Push again to deactivate.
•Push the indicated side of the
control for minimum heat.
•Push again to deactivate.
The heated seat module resets at every ignition run cycle. While the
ignition is in the ON position, activating the high or low heated seat
switch enables heating mode. When activated, they will turn off
automatically when the ignition is turned to the OFF position.
The indicator light will illuminate when the heated seats have been
activated.

Starting the engine
1. Turn the key to 3 (ON) without
turning the key to 4 (START).
2. Turn the key to 4 (START), then
release the key as soon as the
engine starts. Excessive cranking
could damage the starter.
Note:If the engine does not start within five seconds on the first try,
turn the key to OFF, wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.
Using the engine block heater (if equipped)
Use of an engine block heater is strongly recommended if you live in a
region where temperatures reach -10°F (-23°C) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.
To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.

Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
Do not put engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
•Add Motorcraft Premium Gold Engine Coolant
(yellow-colored), VC-7–A (U.S., except CA, OR and NM),
VC-7–B (CA, OR and NM), meeting Ford Specification
WSS-M97B51–A1.
Note:Use of Motorcraft Cooling System Stop Leak Pellets, VC-6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
•Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Specialty Orange Engine Coolant, VC-2 and VC-3
(US) or CXC-209 (Canada), meeting Ford specification
WSS-M97B44–D with the factory-filled coolant.Mixing Motorcraft
Specialty 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, 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.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the “FULL COLD” level. For all other vehicles which have a
