Charging system: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.
•Standard instrument cluster
•Optional instrument cluster
Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range. Check the oil level
and add oil if needed. Refer to
Engine oilin theMaintenance and Specificationschapter.
Engine coolant temperature:Illuminates when the engine coolant
temperature is high. Stop the vehicle as soon as possible, switch off the
engine and let cool. Refer toEngine coolantin theMaintenance and
Specificationschapter.
•Standard instrument cluster
•Optional instrument cluster
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.

TIRE PRESSURE SENSOR FAULT— Displayed when a tire pressure
sensor is malfunctioning, or your spare tire is in use. For more
information on how the system operates under these conditions, refer to
Understanding your Tire Pressure Monitoring System (TPMS)in the
Tires, Wheels and Loadingchapter. If the warning stays on or
continues to come on, contact your authorized dealer as soon as
possible.
BRAKE FLUID LEVEL LOW— Indicates the brake fluid level is low
and the brake system should be inspected immediately. Refer toBrake
fluidin theMaintenance and Specificationschapter.
WASHER FLUID LEVEL LOW— Indicates the washer fluid reservoir
is less than one quarter full. Check the washer fluid level. Refer to
Windshield washer fluidin theMaintenance and Specifications
chapter.
OIL LIFE CHANGE SOON— Displayed when the engine oil life
remaining is 10% or less.
OIL CHANGE REQUIRED— Displayed when the oil life left reaches
0%.
LIFTGATE / GLASS AJAR— Displayed when the liftgate or the
liftgate glass is not completely closed.
TRAILER SWAY REDUCE SPEED— Displayed when your trailer
starts to sway when towing. Refer toTrailer sway controlin the
Drivingchapter for more information.
FOR 4X4 LOW STOP VEHICLE (if equipped)— Displayed when
4X4 LOW is selected while the vehicle is moving. For more information,
refer toUsing the Control Trac 4WD systemin theDrivingchapter.
FOR 4X4 LOW SHIFT TO N (if equipped)— Displayed when 4X4
LOW is selected and the vehicle is stopped. For more information, refer
toUsing the Control Trac 4WD systemin theDrivingchapter.
TO EXIT 4X4 LOW STOP VEHICLE (if equipped)— Displayed
when 2WD is selected while the vehicle is operating in 4X4 LOW. For
more information, refer toUsing the Control Trac 4WD systemin the
Drivingchapter.
TO EXIT 4X4 LOW SHIFT TO N (if equipped)— Displayed when
2WD is selected while the vehicle has been stopped in 4X4 LOW. For
more information, refer toUsing the Control Trac 4WD systemin the
Drivingchapter.

ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The high
pressure fluid could penetrate the sealed parts and cause damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean. In Canada use
Motorcraft Engine Shampoo (CXC-66-A).
•Cover the highlighted areas to prevent water damage when cleaning
the engine.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
•Never wash or rinse any ignition coil, spark plug wire or spark plug
well, or the area in and around these locations.

What you should know about fail-safe cooling
(4.6L V8 engine only)
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.
Fail-safe cooling and engine oil overheat mode (4.6L V8 only)
If the engine coolant and/or engine oil overheat, the vehicle’s fail-safe
modes will reduce engine power to limit engine damage, even with a
total loss of coolant. The vehicle’s range and/or speed will be reduced,
depending on vehicle load, terrain, and outside temperatures.
The instrument cluster provides warnings for each mode.
•Fail-Safe Cooling Mode:The
(Service engine
soon),
(Engine oil pressure), and(Engine coolant
temperature) indicators will be on.
Along with these warning indicators, the engine coolant temperature
gauge will read in the Hot (H) area.
If the engine coolant reaches even hotter temperatures, fail-safe
cooling mode limits engine power more and disables air conditioning.
The engine will switch to alternating cylinder operation to help cool
the engine. The engine will run rough in this mode.
If continued operation increases the engine coolant temperature to a
critical range, the engine will shut down. Steering and braking effort
will increase. Once engine coolant temperature cools, the engine can
be restarted.
•Engine Oil Overheat Mode:The
(Engine coolant temperature)
indicator will be on. The instrument cluster has no separate oil
temperature indicator.
Along with the
(Engine coolant temperature) indicator, the engine
coolant temperature gauge will read in the Hot (H) area.
Oil overheat can be triggered in severe driving conditions, such as
towing heavy loads over mountainous terrain in extreme hot
temperatures. As oil temperature increases, engine and vehicle speed
will be limited. The transmission will also shift differently.
When the engine oil has cooled, the vehicle will perform normally.

•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between the top gears occurs. Unnecessary
shifting of this type could result in reduced fuel economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example; bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
