1999 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS brake

WARNING LIGHTS AND CHIMES
Low fuel
Illuminates as an early reminder of a
low fuel condition indicated on the
fuel gauge. The light comes on when
there is approximately 1/16th of a
tank indicated on the fuel gauge
(refer toFuel Gaugein this chapter for more information). The ignition
must be in the ON position for this lamp to illuminate. The lamp will also
illuminate for several seconds after the ignition is turned to the ON
position regardless of the fuel level.
Oil pressure/Engine coolant
This light will come on when the
key is in the ON position and the:
•engine coolant temperature is
very high
•engine oil pressure is low
The light serves as a notice that a system needs your attention and to
check the engine coolant temperature gauge and the engine oil pressure
gauge.
Refer toEngine coolant temperature gaugeandEngine oil pressure
gaugein this chapter for more information.

Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON
position, the engine is off and the
parking brake is engaged. If the
brake warning lamp does not
illuminate at this time, seek service immediately. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately.
Safety belt
Momentarily illuminates when the
ignition is turned ON to remind you
to fasten your safety belts.
Brake reserve system warning (if equipped)
Illuminates to indicate normal
Hydromax booster reserve system
activation when the engine is OFF
and the service brake pedal is
applied, or when the ignition is in
the ON or START position.
This light may also illuminate momentarily if the engine is running and
the driver turns the steering wheel fully in one direction while braking.
If the light remains on while the engine is running, this indicates
inadequate hydraulic booster pressure or reserve pump system failure.
Safely stop the vehicle as soon as possible and seek service immediately.

3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly installing and securely tightening
the gas cap. After three driving cycles without these or any other
temporary malfunctions present, theService Engine Soonlight should
turn off. (A driving cycle consists of a cold engine startup followed by
mixed city/highway driving.) No additional vehicle service is required.
If theService Engine Soonlight remains on, have your vehicle serviced
at the first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
The Transmission Control Indicator
Light (TCIL), which is located on
the gearshift lever (the word OFF),
may flash steadily if a transmission
malfunction has been detected. It
the TCIL is flashing, contact your Ford dealer as soon as possible. If this
condition persists, damage to the transmission may occur.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned on and the engine
is off. If the light remains on,
continues to flash or fails to
illuminate, have the system serviced
immediately.
Normal is braking is still effective unless the brake warning light(s) also
illuminate(s) with the ignition turned to ON.

GAUGES
Fuel gauge
Displays approximately how much
fuel is in the fuel tank (when the
key is in the ON position). The
ignition should be in the OFF
position while the vehicle is being
refueled. When the gauge first
indicates empty, there is a small
amount of reserve fuel in the tank.
When refueling the vehicle from
empty indication, the amount of fuel
that can be added will be less than the advertised capacity due to the
reserve fuel.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the “L” and “H”).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
Add oil if needed (refer toEngine
oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle checked at your
dealership or by a qualified technician.

To set a speed
•Press SET/SET ACC/SET ACCEL.
For speed control to operate, the
speed control must be ON and
the vehicle speed must be greater
than 48 km/h (30 mph).
If you drive up or down a steep hill, your vehicle speed may vary
momentarily slower or faster than the set speed. This is normal.
Speed control cannot reduce the vehicle speed if it increases above the
set speed on a downhill. If your vehicle speed is faster than the set
speed while driving on a downhill, you may want to shift to the next
lower gear or apply the brakes to reduce your vehicle speed.
If your vehicle slows down more than 16 km/h (10 mph) below your set
speed on an uphill, your speed control will disengage. This is normal.
Pressing RES/RSM/RESUME will re-engage it.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
To set a higher set speed
•Press and hold SET/SET
ACC/SET ACCEL. Release the
control when the desired vehicle
speed is reached or
•Press and release SET/SET
ACC/SET ACCEL. Each press will
increase the set speed by
1.6 km/h (1 mph) or
•Accelerate with your accelerator
pedal. When the desired vehicle
speed is reached, press and release SET/SET ACC/SET ACCEL.

You can accelerate with the accelerator pedal at any time during speed
control usage. Releasing the accelerator pedal will return your vehicle to
the previously programmed set speed.
To set a lower set speed
•Press and hold CST/COAST.
Release the control when the
desired speed is reached or
•Press and release CST/COAST.
Each press will decrease the set
speed by 1.6 km/h (1 mph) or
•Depress the brake pedal. When
the desired vehicle speed is
reached, press SET/SET ACC/
SET ACCEL.
To disengage speed control
•Depress the brake pedal.
Disengaging the speed control will
not erase the previously
programmed set speed.

Make sure the corresponding lights illuminate briefly. If a light fails to
illuminate, have the vehicle serviced.
•If the driver’s safety belt is fastened, the
light may not illuminate.
STARTING THE ENGINE
1. Turn the key to 5 (START)
without pressing the accelerator
pedal and release as soon as the
engine starts. The key will return to
4 (ON).
2. If the temperature is above –12°C (10°F) and the engine does not
start within five seconds on the first try, turn the key to OFF, wait ten
seconds and try again.
3. If the temperature is below –12°C (10°F) and the engine does not
start in fifteen seconds on the first try, turn the key OFF and wait ten
seconds and try again. If the engine does not start in two attempts,
depress the accelerator and start the engine while holding the
accelerator down to the floor. Release the accelerator when the engine
starts.
4. After idling for a few seconds, apply the brake and release the parking
brake.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach –23°C
(–10°F) or below.
For best results, plug the heater in at least three hours before starting
the vehicle. Using the heater for longer than three hours will not harm
the engine, so the heater can be plugged in the night before starting the
vehicle.
