Brake system warning light
To confirm the brake system warning light is functional, it will
momentarily illuminate when the ignition is turned to the on
position when the engine is not running, or in a position
between on and start, or by applying the parking brake when the ignition
is turned to the on position.
If it illuminates when you are driving, check that the parking brake is not
engaged. If the parking brake is not engaged, this indicates low brake
fluid level or a brake system malfunction. Have the system checked
immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer as soon as possible.
Driving extended distances with the parking brake engaged can cause
brake failure and the risk of personal injury.
Charging system (RTT)
Illuminates when the battery is not charging properly. If it stays
on while the engine is running, there may be a malfunction with
the charging system. Contact your authorized dealer as soon as
possible. This indicates a problem with the electrical system or a related
component.
Door ajar (RTT)
Displays when the ignition is on and any door is not completely
closed.
Engine oil pressure (RTT)
Illuminates when the oil pressure falls below the normal range.
Engine coolant temperature (RTT)
Illuminates when the engine coolant temperature is high. Stop
the vehicle as soon as possible, switch off the engine and let
cool.

found in the table under theSettingssection later in this chapter.
Regardless of display mode chosen, when SelectShift Automatic™
transmission (SST) is activated, the cluster will change to the round
tachometer if not already selected. After the round tachometer
displays, other display modes with the bar tachometer can also be
chosen.
•XXX mi (km) to empty: Shows approximate fuel level before the fuel
tank reaches empty. The value is dynamic and can change (raise or
lower) depending on driving style.
•Fuel gauge: Indicates approximately how much fuel is left in the fuel
tank. The fuel gauge may vary slightly when the vehicle is in motion
or on a grade. When the fuel level becomes low, the level indicator will
change to amber. When the fuel level becomes critically low (0 miles
[0 km] to empty), the level indicator will change to red.
Note:When a MyKey® is in use, low fuel warnings will display earlier.
The fuel icon and arrow indicates which side of the vehicle the fuel
filler door is located.
•Bar/Round 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. During SelectShift Automatic™
transmission (SST) use, the currently selected gear will appear in the
display. Refer toTransmissionchapter.
•Engine coolant temperature gauge: Indicates engine coolant
temperature. At normal operating temperature, the level indicator will
be in the normal range. If the engine coolant temperature exceeds the
normal range, stop the vehicle as soon as safely possible, switch off
the engine and let the engine cool.
•Intelligent 4WD (if equipped): displays power distribution between the
front and rear wheels. More power to either front or rear wheels will
be displayed by more area filled in. Also displays the currently
selected terrain management mode.

2.If your vehicle has a keyless start system,move the transmission
selector lever to positionNand use the brakes to bring your vehicle
to a safe stop. When your vehicle has stopped, move the transmission
selector lever to positionPand switch the ignition off by pressing
and holding the button for one second, or pressing it three times
within two seconds.
3. Apply the parking brake.
Guarding Against Exhaust Fumes
WARNING:If you smell exhaust fumes inside your vehicle, have
this checked immediately. Do not drive your vehicle if you smell
exhaust fumes. Carbon monoxide is present in exhaust fumes. Take
precautions to avoid its dangerous effects.
Important Ventilating Information
If you stop your vehicle and leave the engine idling for long periods, we
recommend that you do one of the following:
•Open the windows at least 1 inch (2.5 centimeters).
•Set your climate control to outside air.
ENGINE BLOCK HEATER (IF EQUIPPED)
WARNING:Failure to follow engine block heater instructions
could result in property damage or personal injury.
WARNING:Do not use your heater with ungrounded electrical
systems or two-pronged (cheater) adapters. There is a risk of
electrical shock.
Note:The heater is most effective when outdoor temperatures are below
0°F (-18°C).
The heater acts as a starting aid by warming the engine coolant. This
allows the climate control system to respond quickly. The equipment
includes a heater element (installed in the engine block) and a wire
harness. You can connect the system to a grounded 120–volt A/C
electrical source.

•A coolant concentration of 60% will provide improved freeze point
protection. Engine coolant concentrations above 60% will decrease the
overheat protection characteristics of the engine coolant and may
cause engine damage.
If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
freeze and corrosion protection characteristics of the engine coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme climates should use prediluted
engine coolant for optimum cooling system and engine protection.
Engine Fluid Temperature Management (If Equipped)
WARNING:To reduce the risk of collision and injury, be prepared
that the vehicle speed may reduce and the vehicle may not be able
to accelerate with full power until the fluid temperatures reduce.
Your vehicle has been designed to pull a trailer, but because of the added
load, the vehicle’s engine may temporarily reach higher temperatures
during severe operating conditions such as ascending a long or steep
grade while pulling a trailer in hot ambient temperatures.
At this time, you may notice your engine coolant temperature gauge
needle move toward the H and the POWER REDUCED TO LOWER
TEMP message may appear in the information display.
You may notice a reduction in the vehicle’s speed caused by reduced
engine power. Your vehicle has been designed to enter this mode if
certain high temperature/high load conditions take place in order to
manage the engine’s fluid temperatures. The amount of speed reduction
will depend on the vehicle loading, towing, grade, ambient temperature,
and other factors. If this occurs, there is no need to pull off the road.
The vehicle can continue to be driven while this message is active.
The air conditioning may also cycle on and off during severe operating
conditions to protect overheating of the engine. When the engine coolant
temperature decreases to a more normal operating temperature, the air
conditioning will turn on once again.

If you notice any of the following:
•the engine coolant temperature gauge moves fully into the red (hot)
area
•the coolant temperature warning light illuminates
•the service engine soon indicator illuminates
1. Pull off the road as soon as safely possible and place the vehicle inP
(Park).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After several minutes, if this does not
happen, follow the remaining steps.
3. Turn the engine off and wait for it to cool before checking the coolant
level.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
4. If the coolant level is normal, you may restart your engine and
continue on.
5. If the coolant is low, add coolant, restart the engine and take your
vehicle to an authorized dealer. SeeAdding engine coolantin this
chapter for more information.
Refer to fail-safe cooling for additional information.
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.
