engine FORD E SERIES 2012 4.G Service Manual

WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracwith RSCsystem. In addition, installing any
stereo loudspeakers may interfere with and adversely affect the
AdvanceTracwith RSCsystem. Install any aftermarket stereo
loudspeaker as far as possible from the front center console, the
tunnel, and the front seats in order to minimize the risk of interfering
with the AdvanceTracwith RSCsensors. Reducing the effectiveness
of the AdvanceTracwith RSCsystem could lead to an increased risk
of loss of vehicle control, vehicle rollover, personal injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracwith RSCsystem is an indication that
at least some of the tires have exceeded their ability to grip the road;
this could reduce the operator’s ability to control the vehicle,
potentially resulting in a loss of vehicle control, vehicle rollover,
personal injury and death. If your AdvanceTracwith RSCsystem
activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracwith RSCsystem, the stability control light and
TCS OFF light will illuminate steadily. Verify that the AdvanceTrac
with RSCsystem is not manually disabled. Press the TCS OFF button
located on the center of the instrument panel. If the stability control
light still illuminates steadily, have the system serviced by an
authorized dealer immediately. Operating your vehicle with
AdvanceTracwith RSCdisabled could lead to an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
The AdvanceTracwith RSCsystem automatically enables each time
the engine is started. All features of the AdvanceTracwith RSCsystem
(TCS, ESC, and RSC) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.

The AdvanceTracwith RSC
system includes a TCS OFF button
on the center of the instrument
panel, a stability control light and a
TCS OFF light in the instrument
cluster. The stability control light in
the instrument cluster will
illuminate temporarily during start-up as part of a normal system
self-check, or during driving if a driving situation causes the
AdvanceTracwith RSCsystem to operate. If the stability control light
and TCS OFF light illuminate steadily, verify that the AdvanceTracwith
RSCsystem is not manually disabled by pressing the TCS OFF button
located on the center stack of the instrument panel. If the stability
control light and TCS OFF light remain steadily illuminated, or if the
message center (if equipped) displays SERVICE RSC NOW, have the
system serviced by an authorized dealer immediately.
When AdvanceTracwith RSCperforms a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTracwith RSCyou may
experience the following:
•A slight deceleration of the vehicle
•The stability control light will flash.
•A vibration in the pedal when your foot is on the brake pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction control system (TCS)
Traction control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem; engine traction control and brake traction
control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction control is most active at low speeds.
Driving

Owners Guide, 1st Printing
USA(fus)

During traction control events, the stability control light in the
instrument cluster will flash.
If the TCS is activated excessively in a short period of time, the braking
portion of the system may become temporarily disabled to allow the
brakes to cool down. In this situation, TCS will use only engine power
reduction or transfer to help control the wheels from over-spinning.
When the brakes have cooled down, the system will regain all features.
Anti-lock braking, RSC, and ESC are not affected by this condition and
will continue to function during the cool-down period.
The engine traction control and brake traction control system may be
deactivated in certain situations. SeeSwitching off AdvanceTracwith
RSC.
Electronic stability control (ESC)
Electronic stability control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During ESC events, the stability control light in the instrument cluster
will flash.
Certain adverse driving maneuvers may activate the ESC system, which
include but are not limited to:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter).
Roll Stability Control™ (RSC)
Roll Stability Control™ (RSC) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSCoperates by detecting the
vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.
Driving

During an event that activates the RSC, the stability control light in the
instrument cluster will flash.
Certain adverse driving maneuvers may activate the RSCsystem, which
include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
Traction control
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off the traction control system may be beneficial
because the wheels are allowed to spin. This will restore full engine
power and will enhance momentum through the obstacle. To switch off
the traction control, press the TCS OFF button below 20 mph (32 km/h).
Full features of the traction control system can be restored by pressing
the TCS OFF button again or if the vehicle is above 20 mph (32 km/h) or
by turning off and restarting the engine.
If you switch off the traction control system below 20 mph (32 km/h),
the TCS OFF light will illuminate steadily. Pressing the TCS OFF button
again or if the vehicle is above 20 mph (32 km/h) will turn off the TCS
OFF light. The switch will not allow partial traction control system
disabling above 20 mph (32 km/h).
In R (Reverse), ABS and the engine traction control and brake traction
control features will continue to function; however, ESC and RSCare
disabled.

STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(If the fluid level is below the FULL COLD range on the dipstick).
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark, as
this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.

AUTOMATIC TRANSMISSION OPERATION
Understanding the gearshift positions of the 4–speed automatic
transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage during coasting or deceleration. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
This vehicle is equipped with an adaptive transmission shift strategy.
Adaptive transmission shift strategy offers the optimal transmission
operation and shift quality. When the vehicle’s battery has been
disconnected for any type of service or repair, the transmission will need
to relearn the normal shift strategy parameters, much like having to reset
your radio stations when your vehicle battery has been disconnected.
The adaptive transmission shift strategy allows the transmission to
relearn these operating parameters. This learning process could take
several transmission upshifts and downshifts; during this learning
process, slightly firmer shifts may occur. After this learning process,
normal shift feel and shift scheduling will resume.
P (Park)
This position locks the transmission and prevents the rear wheels from
turning.
To put your vehicle in gear:
1. Start the engine
2. Press the brake pedal
3. Move the gearshift lever into the desired gear
To put your vehicle in P (Park):
1. Come to a complete stop
2. Move the gearshift lever and securely latch it in P (Park)

With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Overdrive) with Tow/Haul off
D (Overdrive) with tow/haul off is the normal driving position for the
best fuel economy. The overdrive function allows automatic upshifts and
downshifts through gears one through five.
D (Overdrive) with Tow/Haul on
The tow/haul feature improves transmission operation when towing a
trailer or a heavy load. All transmission gear ranges are available when
using tow/haul.
Driving

To activate tow/haul, press the
button on the end of the gearshift
lever.
The TOW HAUL indicator light will
illuminate in the instrument cluster.
Tow/haul delays upshifts to reduce frequency of transmission shifting.
Tow/haul also provides engine braking in all forward gears when the
transmission is in the D (Overdrive) position; this engine braking will
slow the vehicle and assist the driver in controlling the vehicle when
descending a grade. Depending on driving conditions and load
conditions, the transmission may downshift, slow the vehicle and control
the vehicle speed when descending a hill, without the accelerator pedal
being pressed. The amount of downshift braking provided will vary based
upon the amount the brake pedal is depressed.
To deactivate the tow/haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The TOW HAUL light
will no longer be illuminated.
When you shut-off and restart the engine, the transmission will
automatically return to normal D (Overdrive) mode (Tow/Haul OFF).
WARNING:Do not use the tow/haul feature when driving in icy
or slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.
3 (Third)
Transmission starts and operates in third gear only.
Used for improved traction on slippery roads. Selecting 3 (Third)
provides engine braking.
2 (Second)
Use 2 (Second) to start-up on slippery roads or to provide additional
engine braking on downgrades.
