POWER STEERING FLUID
CHECK Note:
The power steering cap has both a
cold and hot indicator on the dipstick.
1. Start the engine and let it run until it reaches normal operating temperature
(the engine coolant temperature gauge
indicator will be near the center of the
normal area between H and C).
2. While the engine idles, turn the steering
wheel left and right several times.
3. Turn the engine off.
4. Check the fluid level on the dipstick. It should be between the arrows in the
FULL range on the side of the dipstick
with the words MAX. HOT at the top.
Do not add fluid if the level is within
this range.
5. If the fluid is low, add fluid in small amounts, continuously checking the
level until it reaches the FULL range.
Be sure to put the dipstick back in the
reservoir.
Steering linkage lubrication points
There are nine lubrication points on the
steering linkage: See Capacities and
Specifications (page 156).

Note:
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after handling.
Your vehicle is equipped with a
Motorcraft® maintenance-free battery
which normally does not require additional
water during its life of service.
For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
It is recommended that the negative
battery cable terminal be disconnected
from the battery if you plan to store your
vehicle for an extended period of time.
To ensure proper operation of the battery
management system (BMS), any electrical
devices that are added to the vehicle
should not have their ground connection
made directly at the negative battery post.
A connection at the negative battery post
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: Electrical or electronic accessories
or components added to the vehicle by the
dealer or the owner may adversely affect
battery performance and durability and may
also affect the performance of other
electrical systems in the vehicle.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
that matches the electrical requirements
of the vehicle. Note:
Always dispose of automotive
batteries in a responsible manner. Follow
your local authorized standards for disposal.
Call your local authorized recycling center
to find out more about recycling automotive
batteries.
Battery relearn
When the battery is disconnected or a new
battery installed:
• The transmission must relearn its
adaptive strategy. As a result of this,
the transmission may shift firmly. This
operation is considered normal and will
not affect function or durability of the
transmission. Over time the adaptive
learning process will fully update
transmission operation to its optimum
shift feel.
• The clock and the preset radio stations
must be reset once the battery is
reconnected.
• Your vehicle ’s engine is electronically
controlled by a computer, some control
conditions are maintained by power
from the battery, the engine must
relearn its idle and fuel trim strategy.
When the battery is disconnected or a new
battery is installed, begin the battery
relearn process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift lever in P (Park), turn
off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one
minute.

5. Turn the A/C on and allow the engine
to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven
to relearn the idle and fuel trim
strategy.
FUEL FILTER
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.

Stripes or Graphics (If Equipped)
Hand washing your vehicle is preferred
however, pressure washing may be used
under the following conditions:
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than
179°F
(82°C).
• Use a spray with a 40 degree wide
spray angle pattern.
• Keep the nozzle at a
12 in (305 mm)
distance and 90 degree angle to your
vehicle's surface.
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
Underbody
Regularly clean the underside of your
vehicle using water. Keep body and door
drain holes free of debris or foreign
material.
Under Hood
For removing black rubber marks from
under the hood we recommend Motorcraft
Wheel and Tire Cleaner or Motorcraft Bug
and Tar Remover.
CLEANING THE 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 on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
Note: If your vehicle has an engine cover
remove the cover before application of
Motorcraft Engine Shampoo and Degreaser.
Immediately rinse away any over spray.
• Never wash or rinse the engine while it
is hot or 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.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE WHEELS
1. Regularly clean them with a wheel cleaner. We recommend that you use
Ford approved wheel cleaner if
available.
2. Remove dirt and brake dust with a sponge.
3. Remove tar and grease with a bug and
tar remover. We recommend that you
use Ford approved bug and tar remover
if available.
4. Thoroughly rinse the wheels with water
after cleaning.
131
2021 Motorhome (TY3) Canada/United States of America, enUSA, Edition date: 202010, Second-Printing Vehicle Care

If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before doing so. This
reduces the risk of corrosion of the brake
discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note:
Some car washes could damage
wheel rims and covers.
Note: Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers.
VEHICLE STORAGE
If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make
sure your vehicle stays in good operating
condition.
We engineer and test all motor vehicles
and their components for reliable, regular
driving. Under various conditions,
long-term storage may lead to degraded
engine performance or failure unless you
use specific precautions to preserve engine
components.
General
• Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage. Body
•
Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with
a light grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
Engine
• Change the engine oil and filter prior to
storage because used engine oil
contains contaminates which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast
idle with the climate controls set to
defrost until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
