vehicle as soon as it is safe to do so and
switch the engine off. Have your vehicle
checked as soon as possible. See Engine
Coolant Check (page 238). idk
Engine Oil Pressure
If it illuminates with the engine
running, or when you are driving,
this indicates a malfunction.
Stop your vehicle as soon as it is safe to

STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases helping to warm up the engine.
If the engine idle speed does not slow
down, have your vehicle checked as soon
as possible.
Before starting the engine check the
following:
• Make sure all occupants fasten their
seatbelts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P) or neutral (N).
• Turn the ignition key to the on position.
Note:Do not press the accelerator pedal.
1. Fully press the brake pedal.
2. Turn the key to the start position to
start the engine. Release the key when
the engine starts.
Note:The engine may continue cranking
for up to 15 seconds or until it starts.
Note:If you cannot start the engine on the
first try, wait for a short period and try again.
Failure to Start
If you cannot start the engine after three
attempts, wait 10 seconds and follow this
procedure:
1. Fully press the brake pedal.

your vehicle. A significant decrease in
steering assistance could also occur. The
steering does not lock, but higher effort
could be required to steer your vehicle.
When you switch the ignition off, some
electrical circuits, for example airbags,
also turn off. If you unintentionally switch
the ignition off, shift into neutral (N) and
restart the engine.
1. Switch the ignition off to stop the

Starting and Stopping the Engine

Gray: Indicates that the system is
temporarily unable to provide a warning
on the indicated side(s). This may be
because:
• Your vehicle is below the activation
speed.
• The direction indicator is active.
• Your vehicle is in a dynamic maneuver.
• The road has no or poor lane markings
in the camera field-of-view.
• The camera is obscured or unable to
detect the lane markings due to
environmental, traffic or vehicle
conditions. For example, significant sun
angles, shadows, snow, heavy rain or
fog, following a large vehicle that is
blocking or shadowing the lane or poor
headlamp illumination.See Troubleshooting for additional
information.
Green: Indicates that the system is
available or ready to provide a warning on
the indicated side(s).
Red: Indicates that the system is providing
or has just provided a lane keeping alert
warning.
You can temporarily disable the system at
any time by doing the following:
• Quick braking.
• Fast acceleration.
• Using your direction indicator.
• Evasive steering maneuver.
• Driving too close to the lane markings.
Troubleshooting
Why is the feature not available (line markings are gray) when I can see the lane markings
on the road?
Your vehicle speed is outside the operational range of the feature.
The sun is shining directly into the camera lens.
A quick intentional lane change has occurred.
Your vehicle stays too close to the lane markings.
Driving at high speeds in curves.
The last feature activation occurred a short time ago.
Ambiguous lane markings, for example in construction zones.
Rapid transition from light to dark, or from dark to light.
Sudden offset in lane markings.
ABS or AdvanceTrac™ is active.
There is a camera blockage due to dirt, grime, fog, frost or water on the windshield.
You are driving too close to the vehicle in front of you.
Transitioning between no lane markings to lane markings or vice versa.

Driving Aids

5. Turn the air conditioning (if equipped)
on and allow the engine to idle for at
least one minute.
6. Release the parking brake. With your
foot on the brake pedal and with the
air conditioning on, put the vehicle in
drive (D) and allow the engine to idle
for at least one minute.
• If you do not allow the engine to
relearn its idle trim, the idle quality
of your vehicle may be adversely
affected until the idle trim is
eventually relearned.
7. Drive the vehicle to complete the
relearning process
• The vehicle may need to be driven
10 mi (16 km) or more to relearn the
idle and fuel trim strategy along
with the ethanol content for flexible
fuel vehicles.
If the battery has been disconnected or a
new battery has been installed, the clock
and radio settings must be reset once the
battery is reconnected.
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 Management System (If
Equipped)
The battery management system (BMS)
monitors battery conditions and takes
actions to extend battery life. If excessive
battery drain is detected, the system may
temporarily disable certain electrical
features to protect the battery. Those
electrical accessories affected include the
rear defrost, heated/cooled seats, climate
control fan, heated steering wheel, audio
and navigation system. A message may be
shown in the information displays to alertthe driver that battery protection actions
are active. These messages are only for
notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
Electrical accessory installation
To ensure proper operation of the 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
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
which matches the electrical requirements
of the vehicle. After battery replacement,
or in some cases after charging the battery
with the external charger, the BMS requires
eight hours of vehicle sleep time (key off
with doors closed) to relearn the new
battery state of charge. Prior to relearning
the state of charge, the BMS may disable
electrical features (to protect the battery)
earlier than normal.
ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident, the
alignment of your headlamps should be
checked by your authorized dealer.

Center height of lamp to ground B
25 ft (7.6 m) C
Horizontal reference line D
Vertical Aim Adjustment Procedure
1. Park the vehicle directly in front of a
wall or screen on a level surface,
approximately 25 ft (7.6 m) away.
2. Measure the height of the headlamp
bulb center from the ground and mark
an 8 ft (2.4 m) horizontal reference line
on the vertical wall or screen at this
height.
Note:To see a clearer light pattern for
adjusting, you may want to block the light
from one headlamp while adjusting the
other.
3. Turn on the low beam headlamps to
illuminate the wall or screen and open
the hood.
E142465
4. On the wall or screen you will observe
a flat zone of high intensity light
located at the top of the right hand
portion of the beam pattern. If the top
edge of the high intensity light zone is
not at the horizontal reference line, the
headlamp will need to be adjusted.

5. Locate the vertical adjuster on each
headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in order
to adjust the vertical aim of the
headlamp.
6. Repeat Steps 3 thru 5 to adjust the
other headlamp.
7. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
