You may notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to
drive your vehicle.
The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.
If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park (P).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue. AUTOMATIC TRANSMISSION
FLUID CHECK
The transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
for example if the transmission slips, shifts
slowly or if there are signs of fluid loss.
The transmission fluid and filter on your
vehicle must be replaced at the specified
service interval. See
Scheduled
Maintenance (page 320).
Automatic transmission fluid expands
when warmed. To check the fluid level
consistently and accurately, do the
following:
1. Drive the vehicle until it reaches normal
operating temperature. This may take
up to
20 mi (30 km).
2. Make sure that your vehicle is on level ground.
3. With the engine running, parking brake
engaged and your foot on the brake
pedal, move the gearshift lever through
all of the gear ranges. Allow sufficient
time for each gear to engage.
4. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N) and leave the engine
running.
5. Open the hood. See
Opening and
Closing the Hood (page 186).
6. Remove the dipstick and wipe it with a clean, lint-free cloth. See
Under
Hood Overview (page 189).
7. Replace the dipstick and remove it again to check the fluid level.
8. If the fluid level is correct, replace the dipstick and make sure it is fully seated.
Note: If the fluid level is between the
maximum and minimum marks, the fluid
level is acceptable. Do not add fluid.

Transmission Fluid Level
Low Fluid Level
If the fluid level is at or below the minimum
mark, add fluid immediately. See
Capacities and Specifications (page
269).
Note: If there is no indication of fluid on the
dipstick, have your vehicle checked
immediately.
Correct Fluid Level Make sure that the fluid level is between
the maximum and minimum marks. High Fluid Level
Do not add fluid further than the maximum
mark. Fluid levels above the maximum
mark may cause shift or engagement
concerns and possible damage.
Note:
High fluid levels can be caused by an
overheating condition.
Adding Transmission Fluid
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components and could lead to
transmission damage that may not be
covered by the vehicle Warranty.
Use only recommended transmission fluid
that meets our specifications. See
Capacities and Specifications
(page
269).
Note: Use of a non-approved automatic
transmission fluid may cause internal
transmission component damage.
If necessary, add fluid in
8 fl oz (250 ml)
increments through the filler tube until the
level is correct.
If an overfill occurs, excess fluid should be
removed, have your vehicle checked as
soon as possible.

4.
While the engine idles, turn the steering
wheel left and right several times.
5. Switch the engine off.
6. Recheck the fluid level in the reservoir. Do not add fluid if the level is between
the MIN and MAX range.
7. If the fluid is low, add the proper type of fluid in small amounts, continuously
checking the level until it is between
the MIN and MAX range. See
Capacities and Specifications (page
269). Be sure to put the cap back on the
reservoir.
WASHER FLUID CHECK WARNING
If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze
protection. Failure to use washer fluid with
antifreeze protection in cold weather could
result in impaired windshield vision and
increase the risk of injury or accident. Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See Capacities and
Specifications (page 255).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system. DRAINING THE FUEL FILTER
WATER TRAP - 6.7L DIESEL
Your vehicle is equipped with a diesel fuel
conditioner module located on the
frame-rail under the driver-side floorboard
near the transmission. You should drain water from the
module assembly whenever the
warning light comes on and the
message center directs you to drain the
water separator. This will occur when
approximately 8.45 fl oz (250 ml) of water
accumulates in the module. If you allow
the water level to exceed this level, the
water may pass through to the engine and
may cause fuel injection equipment
damage.
Draining the Diesel Fuel
Conditioner Module (DFCM) WARNING
Do not drain the water-in-fuel
separator while the engine is running.
Failure to follow this warning may
result in fire, serious injury, death or
property damage. Note:
If you drain the diesel fuel conditioner
module while the system is running air will
enter into the fuel system. The engine will
not operate properly if air enters the system.
Note: With fuel tank levels above 3⁄4 tank
it may be necessary to loosen the bowl three
turns before opening the drain. This will
actuate an anti-siphon valve at the fuel and
water separator inlet and prevent the fuel
from siphoning out of the tank.
Note: A loose drain valve can allow air to
enter the fuel system and cause drivetrain
issues. The engine will not operate properly.
Be sure that you fully tighten the drain valve.

•
Maintaining proper steering gear and
power steering pump lubricant levels.
• Checking steering column joint bolts
and steering linkage, particularly for
body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check
steering column joint bolt tightness every
60,000 mi (96,000 km) or annually,
whichever occurs first. Do not overtighten
the bolts.
Hydraulic System
Whenever draining and refilling the power
steering's hydraulic system for any reason,
bleed air from the system before returning
the vehicle to service. Failure to bleed the
hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware
of the proper procedures for filling and
bleeding the system.
SUSPENSION SYSTEM
INSPECTION
Note: Do not adjust air suspension height
to any setting other than the specified
setting. Altering the height setting changes
the driveline angle and may result in
unwarrantable component damage, such
as transmission component damage.
Verify drive axle air suspension height and
height control valve performance at engine
oil change intervals.
Periodically check:
• Condition of spring leaves for evidence
of fatigue, bending or breakage.
• Condition of suspension mounting
brackets and bushings.
• Torque rod mounting fasteners for
tightness. •
For proper suspension alignment.
Maintain proper alignment at all times.
• U-bolts. After the chassis has been
operating under load for
1,000 mi
(1,600 km) or six months (whichever
comes first), the U-bolt nuts must be
re-torqued. Re-torque the U-bolt nuts
every
37,000 mi (60,000 km)
thereafter. Clean and lubricate the
U-bolt and nut threads and seats to
make sure a like new condition when
re-torqueing. See
Spring U-Bolt
Check (page 228).
FRAME AND TOW HOOK
INSPECTION
Your vehicle's chassis is manufactured
with frame rails of either HSLA steel or
heat-treated steel. Handle each in a
specific manner to make sure maximum
service life. Consult the service manual or
an authorized dealer before attempting
frame repair or modification.
It is important, particularly on vehicles that
use tow hooks frequently, to inspect the
front and rear tow hooks for damage or a
loose mounting.
REAR AXLE FLUID CHECK
Your rear axle may have an optional
synthetic lubricant that allows the use of
extended service intervals. A tag on the
filler plug identifies the use of the synthetic
lubricant.
Only use a lubricant that meets
manufacturer specifications. Only use a
lubricant that meets manufacturer
specifications. Use of a non-approved rear
axle lubricant may cause internal axle
component damage. See Capacities and
Specifications
(page 269).

immediate feedback on the overall
condition of your vehicle.
NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™
(Diesel Engine Only)
Your diesel engine is equipped with an
Intelligent Oil-Life Monitor that determines
when you should change the engine oil
based on how your vehicle is used. By using
several important factors in its
calculations, the monitor helps reduce the
cost of owning your vehicle and reduces
environmental waste at the same time. This means you do not have to remember
to change the oil on a mileage-based
schedule. Your vehicle lets you know when
an oil change is due by displaying a
message in the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.
When to expect the OIL CHANGE REQUIRED Message
Vehicle Use and Example
Interval
Normal
7,500– 10,000 mi
(12,000– 16,000 km) Normal commuting with highway driving
No, or moderate, load or towing
