Engine fluid temperature management (EcoBoost engine only)
WARNING:To reduce the risk of collision and injury, be
prepared that the vehicle speed may reduce and the vehicle may
not be able to accelerate with full power until the fluid temperatures
reduce.
Your vehicle has been designed to pull a trailer, but because of the added
load, the vehicle’s engine may temporarily reach higher temperatures
during severe operating conditions such as ascending a long or steep
grade while pulling a trailer in hot ambient temperatures.
At this time, you may notice your engine coolant temperature gauge
needle move toward the H (hot) and the POWER REDUCED TO LOWER
TEMP message may appear on the message center.
You may notice a reduction in the vehicle’s speed caused by reduced
engine power. Your vehicle has been designed to enter this mode if
certain high temperature/high load conditions take place in order to
manage the engine’s fluid temperatures. The amount of speed reduction
will depend on the vehicle loading, towing, grade, ambient temperature,
and other factors. If this occurs, there is no need to pull off the road.
The vehicle can continue to be driven while this message is active.
The air conditioning may also cycle on and off during severe operating
conditions to protect overheating of the engine. When the engine coolant
temperature decreases to a more normal operating temperature, the air
conditioning will turn on once again.
If you notice any of the following:
•the engine coolant temperature gauge moves fully into the red (hot)
area
•the coolant temperature warning light illuminates
•the service engine soon indicator illuminates
1. Pull off the road as soon as safely possible and place the vehicle in P
(Park).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After several minutes, if this does not
happen, follow the remaining steps.

CHECKING THE WIPER BLADES
Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.
CHANGING THE WIPER BLADES
1. Pull the wiper arm away from the
vehicle. Turn the blade at an angle
from the wiper arm. Press the lock
tab to release the blade and pull the
wiper blade down toward the
windshield to remove it from the arm.
2. Attach the new wiper to the wiper
arm and press it into place until a
click is heard.
Replace wiper blades at least once per year for optimum performance.
Poor wiper quality can be improved by cleaning the wiper blades and the
windshield.
To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.
Changing rear window wiper blade
To replace the rear wiper blade:
1. Grab the wiper arm with one
hand close to the arm/blade joint
and pull it as far away from the
glass as possible. Do not use
excessive force because it can break
the wiper arm at the heel. Hold it
there until the next step.

Changing the air filter element
3.5L V6 engine
3.5L V6 EcoBoost engine
1. On the passenger’s side of the air filter housing, release the two
clamps from the air filter housing cover.
2. Lift the passenger’s side of the cover and push
the cover toward the passenger’s side. Release the
three tabs on the cover from the three slots in the
driver’s side of the housing.
3. Carefully separate the cover from the housing.
4. Remove the air filter element from the housing.
5. Wipe the cover and the housing clean to remove
any dirt or debris and to make sure the cover seals
to the housing.
6. Install a new air filter element. Be careful not to crimp the filter element
edges between the housing and the cover. This could cause filter damage
and allow unfiltered air to enter the engine if not properly seated.
7. Lower the driver’s side of the cover and slide the three tabs on the
cover into the three slots in the housing.
8. Lower the passenger’s side of the cover. Engage the two clamps to
secure the cover to the housing.
