SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury and prevent possible
damage to others, your vehicle and its equipment? In this guide, answers
to such questions are contained in comments highlighted by the warning
triangle symbol. These comments should be read and observed.
Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,600 km (1,000 miles) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle for at least 800 km (500 miles) before towing a
trailer or snowplowing.
Do not add friction modifier compounds or special break-in oils during
the first few thousand kilometers (miles) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and specificationschapter for more information on oil
usage.

Transmission fluid temperature gauge (automatic transmission
only):If the gauge is in the:
White area(normal) - the
transmission fluid is within the
normal operating temperature
(between“H”and“C”).
Yellow area(warning)—the
transmission fluid is higher than
normal operating temperature. This
can be caused by special operation
conditions (i.e. snowplowing, towing
or off road use). Refer toSpecial
Operating Conditionsin the
scheduled maintenance guide for
instructions. Operating the
transmission for extended periods of
time with the gauge in the yellow
area may cause internal transmission damage.
Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.
Red area(over temperature)—
the transmission fluid is overheating.
Stop the vehicle to allow the
temperature to return to normal
range.
If the gauge is operating in the
Yellow or Red area, stop the vehicle
and verify the airflow is not
restricted such as snow or debris
blocking airflow through the grill. If
the gauge continues to show high
temperatures, see your Ford dealer.

Clearance lamps (if equipped)
Illuminates when the headlamps or
parking lamps are switched on.
This provides additional visibility of
your vehicle to other drivers on the
road.
Fold-away mirrors
The mirrors can be manually folded forward or backwards for narrow
spaces like driving through an automatic car wash or backing out of a
garage with the trailer tow mirror.
The telescoping feature (if equipped) allows the mirror to extend
approximately 76 mm (3 inches). This feature is especially useful to the
driver when towing a trailer.

Driver Controls

Page 120 of 280

N (Neutral)
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.
(Overdrive)
The normal driving position for the
best fuel economy. Transmission
operates in gears one through four.
(Overdrive) can be deactivated
by pressing the transmission control
switch on the end of the gearshift
lever.
This transmission control indicator
light (TCIL) will illuminate on the
end of the gearshift.
Note:If the Overdrive OFF light
flashes steadily at any time, have
the system serviced immediately.
Drive (not shown)
Drive is activated when the transmission control switch is pressed.
•This position allows for all forward gears except overdrive.
•O/D OFF lamp is illuminated.
•Provides engine braking.
•Use when driving conditions cause excessive shifting from O/D to
other gears. Examples: city traffic, hilly terrain, heavy loads, trailer
towing and when engine braking is required.
•To return to O/D (overdrive mode), press the transmission control
switch. The O/D OFF lamp will not be illuminated.
•O/D (Overdrive) is automatically returned each time the key is turned
off regardless of last mode of operation.

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.
To activate Tow/Haul, press the
button on the end of the gearshift
lever.
The ON light on the end of the
gearshift lever will illuminate when
it is activated.
The TOW HAUL indicator light will illuminate on the end of the gearshift
lever.
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 ON 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).
3 (Third)
Transmission operates up to third gear only.

slipping.
Shifting from 4H (4WD High) to 2H (2WD High)
Move the transfer case lever to 2H
(2WD High) at a stop or any forward
speed up to 88 km/h (55 mph).
With the vehicle at complete stop,
disengage the locking hubs
(optional) by rotating the hub lock
control from LOCK to FREE.

Using the electronic shift 4WD system (if equipped)
Positions of the electronic shift system
The electronic shift 4WD system is designed to allow up to 45
seconds before a shift command is performed. In the event that
conflicting shift commands are selected, allow up to 45 seconds
for the shift command to be performed prior to reporting any
shift concerns to your dealer.
Note:Some noise may be heard as the 4WD system shifts or engages.
This is normal.
2H (2WD High)–For general on-road driving. Sends power to the rear
wheels only.
4H (4WD High)–For winter and off-road conditions. Sends power to
front and rear wheels.
4L (4WD Low)–For low-speed off-road applications that require extra
power such as steep grades, deep sand or pulling a boat out of the water.
Sends power to front and rear wheels.
