direction as the halves rotate together.
If Your Vehicle Gets Stuck In Mud or
Snow
Note: Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute or damage to the transmission and
tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow,
you may rock it out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.

Four-wheel drive (when you select a 4WD
mode) uses all four wheels to power the
vehicle. This increases traction, enabling you
to drive over terrain and road conditions that
a conventional two-wheel drive vehicle
cannot.
Basic Operating Principles
•
Do not use 4X4 mode on dry, hard
surfaced roads. Doing so will produce
excessive noise, increase tire wear and
may damage drive components. 4X4
mode is only intended for consistently
slippery or loose surfaces.
• Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• When driving your vehicle on surfaces
made slippery by loose sand, water,
gravel, snow or ice proceed with care. If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce your
vehicle speed and avoid severe braking.
When your vehicle speed has been reduced
ease your vehicle back onto the road. Do
not turn the steering wheel sharply while
returning your vehicle to the road.
It may be safer to stay on the shoulder of the
road and slow down gradually before
returning to the road. You may lose control
if you do not slow down or if you turn the
steering wheel too sharply or abruptly.
It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than attempt
a sudden return to the road which could
cause your vehicle to slide sideways out of
control or roll over. Remember, your safety
and the safety of others should be your
primary concern. If your vehicle gets stuck WARNING
Do not spin the wheels at over 35 mph
(56 km/h). The tires may fail and injure
a passenger or bystander. Note:
Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, damage to the transmission and
tires may occur or the engine may overheat.
If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your vehicle
(i.e. turn the steering wheel only as rapidly
and as far as required to avoid the
emergency). Excessive steering can result

“Tread Lightly” is an educational program
designed to increase public awareness of
land-use regulations and responsibilities in
our nations wilderness areas. Ford Motor
Company joins the U.S. Forest Service and
the Bureau of Land Management in
encouraging you to help preserve our
national forest and other public and private
lands by “treading lightly”
.
Driving on Hilly or Sloping Terrain
Note: Avoid driving crosswise or turning on
steep slopes or hills.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you will use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer.
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down. When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn around
because this could cause vehicle roll over.
It is better to reverse back to a safe location.
Apply just enough power to the wheels to
climb the hill. Too much power will cause the
tires to slip, spin or lose traction, resulting in
loss of vehicle control. Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral. Disengage overdrive
or move the transmission selector lever to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could lose
control. The front wheels have to be turning
in order to steer your vehicle.
If your vehicle has anti-lock brakes, apply the
brakes steadily. Do not pump the brakes.
Driving on Snow and Ice
WARNING
If you are driving in slippery conditions
that require tire chains or cables, then
it is critical that you drive cautiously. Keep
speeds down, allow for longer stopping
distances and avoid aggressive steering to
reduce the chances of a loss of vehicle
control which can lead to serious injury or
death. If the rear end of your vehicle slides
while cornering, steer in the direction of the
slide until you regain control of your vehicle. 181

Before Towing a Trailer
Practice turning, stopping and backing up to
get the feel of your vehicle-trailer
combination before starting on a trip. When
turning, make wider turns so the trailer
wheels clear curbs and other obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph (113
km/h) during the first 500 miles (800
kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled 50 miles (80
kilometers).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position P to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off automatically when you are
towing on long, steep grades. •
Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and transmission
cooling.
• If your vehicle is equipped with
AdvanceTrac with RSC, this system may
turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed while towing may reduce
this tendency.
• If your vehicle is equipped with
Continuous Controlled Damping
Suspension (CCD Suspension), you can
select NORMAL or SPORT drive control
modes for better experience while towing
a trailer. See Information Displays (page
105
). •
If you are towing a trailer frequently in
hot weather, hilly conditions, at the gross
combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic gear
lubricant (if the axle is not already filled
with it).
See Capacities and
Specifications (page 328).
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in position
P.
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not included
with vehicle.)

BREAKING-IN
You need to break in new tires for
approximately 300 miles (480 kilometers).
During this time, your vehicle may exhibit
some unusual driving characteristics.
Avoid driving too fast during the first 1000
miles (1600 kilometers). Vary your speed
frequently and change up through the gears
early. Do not labor the engine.
Do not tow during the first 1000 miles (1600
kilometers).
REDUCED ENGINE PERFORMANCE
WARNING
Continued operation will increase the
engine temperature and cause the
engine to shut down completely. If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating. See Gauges (page
99). You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine will continue to operate with limited
power for a short time.
If the engine temperature continues to rise,
the fuel supply to the engine will reduce. The
air conditioning will switch off and the engine
cooling fan will operate continually.
1. Reduce your speed gradually and stop
your vehicle as soon as it is safe to do
so.
2. Switch the engine off immediately to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Engine
Coolant Check (page 269).
5. Have your vehicle checked by an authorized dealer as soon as possible. ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving(When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
235
Navigator (TB5) Canada/United States of America, enUSA, First Printing Driving Hints

3. Refill with engine coolant as soon as
possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.
• Brine.
• Any engine coolant mixed with alcohol
or methanol antifreeze or coolant.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
engine coolant.
When adding coolant:
1. Unscrew the cap slowly. Any pressure will escape as you unscrew the cap.
2. Add prediluted engine coolant meeting the correct specification. See Capacities
and Specifications (page 328). 3. Check the coolant level in the coolant
reservoir the next few times you drive
your vehicle.
4. If necessary, add enough prediluted engine coolant to bring the coolant level
to the proper level.
Recycled Engine Coolant
We do not recommend the use of recycled
engine coolant as an approved recycling
process is not yet available.
Used engine coolant should be disposed of
in an appropriate manner. Follow your
community’ s regulations and standards for
recycling and disposing of automotive fluids. Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to have an
authorized dealer increase the coolant
concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection. Engine
coolant concentrations above 60%
decrease the overheat protection
characteristics of the engine coolant and
may cause engine damage.
If you drive in extremely hot climates:
• It may be necessary to have an
authorized dealer decrease the coolant
concentration to 40%.
• A coolant concentration of 40% provides
improved overheat protection. Engine
coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the engine
coolant and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine protection.

What You Should Know About Fail-Safe
Cooling
If you deplete the engine coolant supply,
fail-safe cooling allows you to temporarily
drive your vehicle before you incur
incremental component damage. The
fail-safe distance depends on ambient
temperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge will move to the
red (hot) area and:
the coolant temperature warning
light will illuminate
the service engine soon indicator
will illuminate.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine. When this occurs, your vehicle will still
operate. However:
•
The engine power will be limited.
• This will disable the air conditioning
system.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start your engine. Take your vehicle to an
authorized dealer as soon as possible to
minimize engine damage.
When Fail-Safe Mode Is Activated WARNINGS
Fail-safe mode is for use during
emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in a
safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will have
limited power, will not be able to maintain WARNINGS
high-speed operation, and may completely
shut down without warning, potentially losing
engine power, power steering assist, and
power brake assist, which may increase the
possibility of a crash resulting in serious
injury. Never remove the coolant reservoir
cap while the engine is running or hot.
You have limited engine power when in the
fail-safe mode, so drive your vehicle with
caution. Your vehicle will not maintain
high-speed operation and the engine will
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch off the engine.
2. Tow your vehicle to an authorized dealer.
3. If this is not possible, wait a short period
for the engine to cool.
4. Check the coolant level and add if low.
272
Navigator (TB5) Canada/United States of America, enUSA, First Printing Maintenance

5.
Re-start the engine and drive your vehicle
to an authorized dealer.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Contact an authorized dealer as soon as
possible.
Engine Fluid Temperature Management (If
Equipped) WARNINGS
To reduce the risk of crash 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. Never remove the coolant reservoir
cap while the engine is running or hot.
Your vehicle can pull a trailer, but because
of the added load, your 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 high temperatures. At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED TO
LOWER TEMP message may appear in the
information display.
You may notice a reduction in vehicle speed
caused by reduced engine power. In order
to manage the engine fluid temperatures,
your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on many factors such as vehicle
loading, towing, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to drive
your vehicle 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
normal operating temperature, the air
conditioning will turn on once again. If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:
1. Pull off the road as soon as safely
possible and shift the transmission into
P
.
2. Leave the engine running until the coolant temperature gauge needle
moves away from the red (hot) area. After
several minutes, if the temperature does
not drop, follow the remaining steps.
3. Switch the engine off and wait for it to cool before checking the coolant level.
4. If the coolant level is normal, restart your
engine and continue.
5. If the coolant is low, add coolant, and restart the engine. See
Adding Engine
Coolant or How Fail-Safe Cooling Works
in this chapter for more information.
