GAUGES
Base cluster with automatic transmission shown. Metric similar.
1. Engine oil pressure gauge: Indicates engine oil pressure. The
needle should stay in the normal operating range (between L and H). If
the needle falls below the normal range, stop the vehicle, turn off the
engine and check the engine oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked at your authorized dealer.
2. 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.
WARNING: Never remove the coolant reservoir cap while the
engine is running or hot.

Yellow area The transmission fluid is higher than normal operating
temperature. This can be caused by special operation conditions (i.e.
snowplowing, towing or off road use). Refer to Special operating
conditions in the scheduled maintenance information for instructions.
Operating the transmission for extended periods of time with the gauge
in the yellow area may cause internal transmission damage.
Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.
Red area The transmission fluid is overheating. Stop the vehicle to allow
the temperature to return to normal range.
If the gauge is operating in the yellow or red area, stop the vehicle and
verify the airflow is not restricted such as snow or debris blocking airflow
through the grill. If the gauge continues to show high temperatures, see
your authorized dealer.
4. Fuel gauge: Indicates approximately how much fuel is left in the fuel
tank (when the ignition is in the on position). The fuel gauge may vary
slightly when the vehicle is in motion or on a grade. The fuel icon and
arrow indicates which side of the vehicle the fuel filler door is located.
Refer to Filling the tank in the Maintenance and Specifications
chapter for more information.
5. Speedometer: Indicates the current vehicle speed.
6. Tachometer: Indicates the engine speed in revolutions per minute.
Driving with your tachometer pointer continuously at the top of the scale
may damage the engine.
Odometer and trip odometer: The odometer is displayed on the lower
line in the message center and registers the total accumulated distance
the vehicle has traveled. For trip odometer, refer to Standard message
center or Optional message center in this chapter.
STANDARD MESSAGE CENTER
Your vehicle’s message center is capable of monitoring many vehicle
systems and will alert you to potential vehicle problems and various
conditions with an informational message followed by a long indicator
chime.
The message center display is located in the instrument cluster and the
controls are located on the steering wheel.Instrument Cluster

The power point can switch to a fault mode when it is overloaded,
overheated, or shorted. For overloading and shorting conditions, unplug
your device and turn the ignition key off then on. For an overheating
condition, let the system cool off, then turn the ignition key off then on.
The 110V AC power point can provide power whenever the vehicle
ignition is in the on position and the power point green indicator light
located in the top left corner is turned on. Refer to the indicator light
code below for the power point status.
Indicator light codes
Green light is on — Power point is ready to supply power
Green light is off — Power point power supply is off. Ignition is not in
the on position
Green light is blinking — Power point is in fault mode
Note: The 110V AC power point will turn off after 13 minutes if the
ignition is in the on position without the engine running. Keep the
engine running or cycle the ignition before the 13 minute time-out to
keep the inverter on.
POWER WINDOWS (IF EQUIPPED)
WARNING: Do not leave children unattended in the vehicle and
do not let children play with the power windows. They may
seriously injure themselves.
WARNING: When closing the power windows, you should verify
they are free of obstructions and ensure that children and/or
pets are not in the proximity of the window openings.
Press and pull the window switches
to open and close windows.
• Press down (to the first detent)
and hold the switch to open.
• Pull up (to the first detent) and
hold the switch to close.
Rear Window Buffeting: When one or both of the rear windows are
open, the vehicle may demonstrate a wind throb or buffeting noise. This
noise can be alleviated by lowering a front window approximately 2–3 in.

Note: Ten or more switch activations within one minute, or repeated
fold/unfolding of the mirrors while holding the switch rearward during the
full travel may cause the system to disable the fold/unfold function to
protect the motors from overheating. Should this occur, wait approximately
3 1
2
minutes for the system to reset and function to return to normal.
Note: The power-fold mirrors are designed to operate while the vehicle
is stationary or traveling at moderate speeds. If you attempt to
power-fold the mirrors at high speeds, they may not fully fold
forward/rearward - slow down and power-fold or manually fold the
mirrors in order to complete the fold operation.
Note: If the power fold/telescope mirror glass appears loose or vibrates
when driving, it is possible that the mirrors have been manually folded or
telescoped. To minimize the vibration, ensure that the mirrors are
electronically folded and telescoped in/out with the switches on the door
trim panel. If the power fold mirrors are out of sync, electronically
power-fold the mirrors to re-sync the motors. This will cause a loud “click”
and the mirrors will jerk during re-synchronization. This is normal.
Telescoping mirrors (if equipped)
The telescoping feature allows the
mirror to extend approximately
2.75 inches (70 mm). This feature is
especially useful to the driver when
towing a trailer. Mirrors can be
manually pulled out or pushed in to
the desired telescopic position.
If equipped with PowerScope™
power telescoping mirrors, you can
simultaneously position both mirrors
using the power telescope switch
found on the door trim panel.
• To telescope the mirrors
outboard, press and hold the left
side of the power telescope switch until the mirrors reach their
desired position. When the end of travel is reached, it is normal to
hear the power telescoping motors running as long as you continue to
hold the switch.Driver Controls

When climbing a steep slope or hill,
start in a lower gear rather than
downshifting to a lower gear from a
higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of stalling.
If you do stall out, do not try to
turn around because you might roll
over. It is better to back down to a
safe location.
Apply just enough power to the
wheels to climb the hill. Too much
power will cause the tires to slip,
spin or lose traction, resulting in
loss of vehicle control.
Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral; instead,
manually shift to a lower gear. Your
vehicle has anti-lock brakes, apply
the brakes steadily. Do not “pump”
the brakes.
Driving on snow and ice
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions. Driving

Note: During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.
• DO NOT MIX different colors or types of coolant in your vehicle.
Mixing of engine coolants may harm your engine’s cooling system.
Only use engine coolant that meets the Ford specification. Generic
coolants for all makes and models may not meet the Ford
specification. The use of an improper coolant may harm engine and
cooling system components and may void the warranty. See
Capacities and Specifications for more information.
• In case of emergency, a large amount of water without engine coolant
may be added in order to reach a vehicle service location. In this
instance, the cooling system must be drained, chemically cleaned, and
refilled with prediluted engine coolant as soon as possible per the
instructions in the Workshop Manual. 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 and a non-pressurized
cap on the coolant recovery system, add prediluted engine coolant to
the FULL COLD level on the coolant recovery reservoir when the engine
is cool.
For vehicles with overflow coolant systems and a pressure relief
cap on the radiator, follow these steps to add engine coolant:
1. Turn off the engine and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the radiator.
3. Slowly turn the coolant pressure relief cap counterclockwise until
pressure begins to release.
4. Step back while the pressure releases.
5. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap. Maintenance and Specifications

6. Remove the cap from the engine coolant reservoir.
7. Fill the coolant reservoir slowly with prediluted engine coolant to the
FULL COLD level, or between the MIN and MAX marks, or the COLD
FILL RANGE, as listed on the engine coolant reservoir (depending upon
application).
8. Add prediluted engine coolant to the radiator until the coolant is
visible and the radiator is almost full.
9. Install the cap to the engine coolant reservoir. Tighten the cap in
order to prevent coolant loss.
10. Install the pressure relief cap to the radiator. Tighten the cap in
order to prevent coolant loss.
For vehicles which have a coolant degas system with a
pressurized cap on the coolant reservoir, follow these steps to add
engine coolant:
1. Turn off the engine and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir.
3. Slowly turn the coolant pressure relief cap counterclockwise until
pressure begins to release.
4. Step back while the pressure releases.
5. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
6. Fill the coolant reservoir slowly with prediluted engine coolant to
within the FULL COLD level, or between the MIN and MAX marks, or
the COLD FILL RANGE, as listed on the engine coolant reservoir
(depending upon application).
Whenever you add coolant, check the coolant concentration. See
Checking the engine coolant in this chapter. If the concentration is not
50%, drain some coolant and adjust the concentration. It may take
several drains and additions to obtain a 50% coolant concentration.
The next few times you drive the vehicle, check the coolant level in the
coolant reservoir. If necessary, add enough prediluted engine coolant to
bring the coolant level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized 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.Maintenance and Specifications

What you should know about fail-safe cooling (if equipped)
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.
WARNING: If fail-safe cooling activates, pull off the road as
soon as safely possible and turn the engine off. The engine may
automatically shut off while driving without further indication.
How fail-safe cooling works
If the engine begins to overheat:
• The engine coolant temperature gauge will move to the red (hot)
area.
• The message center will indicate the engine is overheating.
• 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 restarted. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.
When fail-safe mode is activated
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.Maintenance and Specifications
