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; instead,
disengage overdrive or manually
shift to a lower gear. When
descending a steep hill, avoid
sudden hard braking as you could
lose control. When you brake hard,
the front wheels can’t turn and if
they aren’t turning, you won’t be
able to steer. The front wheels have to be turning in order to steer the
vehicle. Rapid pumping of the brake pedal will help you slow the vehicle
and still maintain steering control.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
“pump” the brakes.
Driving on snow and ice
Four–wheel drive vehicles have advantages over two–wheel drive
vehicles in snow and ice but can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although a four–wheel drive vehicle may
accelerate better than a two-wheel drive vehicle in snow and ice, it won’t
stop any faster, because as in other vehicles, braking occurs at all four
wheels. Do not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, apply the brake forcefully and
steadily. Do not “pump” the brakes. Refer to theBrakessection of this
chapter for additional information on the operation of the anti-lock brake
system.

Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.
POWER STEERING FLUID
Check the power steering fluid. Refer to thescheduled maintenance
informationfor the service interval schedules. If adding fluid is
necessary, use MERCONAT F.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the “MIN” and
“MAX” lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating range the performance of the system
could be compromised; seek service from your authorized dealer
immediately.
