If the engine, transmission, AWD system components or axles are
submerged in water, their fluids should be checked and changed, if
necessary.
Driving through deep water may damage the engine or
transmission.
If the front or rear axle is submerged in water, the axle lubricant and
PTU (Power Transfer Unit) lubricant should be checked and changed if
necessary.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
“Tread Lightly” is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest Service and the Bureau of Land
Management in encouraging you to help preserve our national forest and
other public and private lands by “treading lightly.”
Driving on hilly or sloping terrain
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down.Avoid driving crosswise or turning on steep
slopes or hills.A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
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.

TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, i.e., if the transmission slips or
shifts slowly or if you notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic
during hot weather or pulling a trailer, the vehicle should be
turned off until normal operating temperatures are reached to
allow the fluid to cool before checking. Depending on vehicle use,
cooling times could take up to 30 minutes or longer.
WARNING:The dipstick cap and surrounding components may
be hot; gloves are recommended.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow a minimum of 10 seconds for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer toIdentifying components in the engine compartment
in this chapter for the location of the dipstick. (For vehicles with the
EcoBoost™ engine, move the air filter assembly aside to access the
transmission dipstick).
WARNING:Use gloves when moving the air filter assembly;
components will be hot.
For vehicles equipped with the EcoBoost™ engine, do the
following:
A. Shut the engine off.

H. Rotate the air filter assembly 90
degrees counterclockwise and
reinstall into the rubber hose.
I. Tighten the clamp (1).
J. The transmission fluid level indicator can now be accessed.
WARNING:Do not run engine with the air filter disconnected.
Start the engine and continue with Step 6.
6. Install the dipstick making sure it is fully seated in the filler tube by
turning it to the locked position.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the designated areas for normal operating temperature.
Low fluid level
If the fluid level is below the MIN
range of the dipstick, add fluid to
reach the hash mark level.Note:If
the fluid level is below the MIN
level, do not drive the vehicle. An underfill condition may cause shift
and/or engagement concerns and/or possible damage.
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 180°F-200°F (82°C-93°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.

The transmission fluid level should
be targeted within the cross-hatch
area if at normal operating
temperature 180°F-200°F
(82°C-93°C).
High fluid level
If the fluid level is above the MAX
range of the dipstick, remove fluid
to reach the hashmark level.Note:
Fluid level above the MAX level may
cause shift and/or engagement concerns and/or possible damage.
High fluid levels can be caused by an overheating condition. If your
vehicle has been operated for an extended period at high speeds, in city
traffic during hot weather or pulling a trailer, the vehicle should be
turned off until normal operating temperatures are reached. Depending
on vehicle use, cooling times could take up to 30 minutes or longer.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in the
Maintenance product specifications and capacitiessection in this
chapter.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 1/2 pint
(250 ml) increments through the
filler tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
An overfill condition of
transmission fluid may cause shift and/or engagement concerns
and/or possible damage.
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.

Be sure to ask your Ford or Lincoln Mercury dealership service advisor
or technician about the multi-point vehicle inspection. It’s a
comprehensive way to perform a thorough inspection of your vehicle. It’s
your checklist that gives you immediate feedback on the overall
condition of your vehicle. You’ll know what’s been checked, what’s okay,
as well as those things that may require future or immediate attention.
The multi-point vehicle inspection is one more way to keep your vehicle
running great!
Mutli-point inspection - Recommended at every visit
❑Check and top-up fluid levels: brake, coolant recovery reservoir, manual and automatic transmission (if equipped with an
underhood dipstick), power steering (if equipped) and window washer
❑Inspect tires for wear and check air pressure, including spare.
❑Check exhaust system for leaks, damage, loose parts and foreign material.
❑Check battery performance.
❑Check operation of horn, exterior lamps, turn signals and hazard warning lights.
❑Check radiator, coolers, heater and air conditioning hoses.
❑Inspect windshield washer spray and wiper operation.
❑Check windshield for cracks, chips and pitting.
❑Inspect for oil and fluid leaks.
❑Inspect engine air filter.
❑Inspect half shaft dust boots, if equipped.
❑Check shocks and struts and other suspension components for leaks and damage.
❑Inspect steering and linkage.
❑Inspect accessory drive belt(s).
❑Inspect clutch operation, if equipped.
