ENGINE OIL DIPSTICK MINA
MAXB ENGINE OIL CHECK
To check the engine oil level consistently
and accurately, do the following:
1.
Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
2. Run the engine until it reaches normal operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes
for the oil to drain into the oil pan.
Checking the engine oil level too soon
after you switch the engine off may result
in an inaccurate reading.
5. Open the hood.
See Opening and
Closing the Hood (page 377). 6. Remove the dipstick and wipe it with a
clean, lint-free cloth.
See Under Hood
Overview (page 379).
7. Reinstall the dipstick and remove it again
to check the oil level.
See Engine Oil
Dipstick (page 380).
8. Make sure that the oil level is between the maximum and minimum marks. If the
oil level is at the minimum mark, add oil
immediately.
See Capacities and
Specifications (page 440).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.

2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, 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
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 539).
The automatic transmission does not have
a transmission fluid dipstick. Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
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.

Tire Change Procedure WARNING: Only use replacement
tires and wheels that are the same size,
load index, speed rating and type (such as
P-metric versus LT-metric or all-season
versus all-terrain) as those originally
provided by Ford. The recommended tire
and wheel size may be found on either the
Safety Compliance Certification Label
(affixed to either the door hinge pillar,
door-latch post, or the door edge that
meets the door-latch post, next to the
driver's seating position), or the Tire Label
which is located on the B-Pillar or edge of
the driver's door. If this information is not
found on these labels, then you should
contact your authorized dealer as soon as possible. Use of any tire or wheel not
recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of
loss of vehicle control, vehicle rollover,
personal injury and death.
WARNING:
To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park (P),
set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel, place
an appropriate block or wheel chock on
the right rear wheel. WARNING: Do not attempt to change
a tire on the side of the vehicle close to
moving traffic. Pull far enough off the road
to avoid the danger of being hit when
operating the jack or changing the wheel. WARNING: Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. If you
are unsure if the jack capacity is adequate,
contact the authorized dealer.

WARNING: Switch off the running
boards before jacking or placing any object
under your vehicle. Never place your hand
between the extended running board and
your vehicle. A moving running board may
cause injury. WARNING: Only use the spare wheel
carrier to stow the wheel provided with
your vehicle. Other wheel sizes could
cause the spare wheel carrier to fail if it
does not fit securely or is too heavy. 1.
Park the vehicle on firm, level ground and
activate the hazard flashers. 2. Apply the parking brake, place the
transmission in park (P) and switch the
ignition off.
3. Block the wheels diagonally opposite the
flat tire, for example, if the left front tire
is flat, block the right rear wheel.
Removing the Jack and Tools
Note: Pay close attention to the orientation
of the jack and tool kit bag, because it needs
to be reinstalled after changing the tire.
1. Open the liftgate and lift the load floor behind the third row seat. If your vehicle
has an access panel, you need to then
unlatch and remove this panel.
2. Remove the wing nut by turning it counterclockwise.
3. Remove the jack and tool kit bag from the bracket, loosen the straps and
remove the tool bag from the jack. Removing the Spare Tire
1.
Remove the swivel wrench from the tool
kit bag, open the spare tire winch access
plug at the bottom of the compartment
for the jack and tools tray.
2. Insert the swivel wrench through the access hole in the floor to engage the
winch. Turn the handle counterclockwise
until the tire lowers to the ground and
the cable is slightly slack.
